## Key facts

| Fact | Value |
| --- | --- |
| Deployment | SaaS |
| Hosting regions | Unknown |
| Australian region | Unknown |
| Assurance | ISO/IEC 42001:2023 (badge on the product page states Thomson Reuters 'achieves ISO 42001 certification for Responsible AI'; the Australian AI campaign page states it was achieved 'for Westlaw and CoCounsel'; certificate, certifying body and scope statement not read) |
| Training on customer content | Unknown |
| Retention | No retention period is published for Westlaw Precision Australia. The Thomson Reuters Privacy Statement (last updated 31 July 2026) says personal information is retained under an enterprise records retention schedule that varies by Service, business function, country, record class and record type, and states no period. The CoCounsel Australia FAQ says retention of user content and prompts is configurable at organisation level with a Thomson Reuters client manager and that users can delete their own content and prompts in-product; that answer is about CoCounsel, not this tier. |
| Integrations | CoCounsel, Practical Law Australia, Microsoft 365 Copilot, HighQ |
| Legal content coverage | Westlaw's Australian collection as described on the product page: authorised law reports covering the High Court, the Federal Court, the Fair Work Commission and state superior courts, including the Commonwealth Law Reports; The Laws of Australia across 320-plus topics and every Australian jurisdiction; the Australian Law Journal; and forms and precedents (Australian Commercial, NSW and Victorian), across 21 practice areas. AI-Assisted Research is described as grounded in primary law content 'including all the Authorised Law Reports'. KeyCite is the citator, and the page states advanced KeyCite features trace precedents and the authority of cases within the Commonwealth Law Reports. Which collections sit in a subscription is set by the plan. |
| Pricing | No price is published for Westlaw Precision Australia. The Thomson Reuters Australia store publishes Westlaw Australia plans for 1-3 practitioners (Essentials from $133 per month and Essentials plus 2 Practice Areas from $340 per month, each a 12-month subscription for one practitioner) and a quote-based Enterprise plan for 4 or more practitioners, with practice areas, authorised law reports and journals sold as add-on subscriptions or pay-per-view; that page names no Precision tier and no Precision price, and the only calls to action on the Precision page are a demo request and a contact form. |
| Australian presence | Yes. The Australian contracting entity for Westlaw Precision Australia is not published and no ACN or ABN was found. Thomson Reuters' Australian modern slavery transparency statement (fiscal year ending 31 December 2021, approved 3 May 2022) is made by two Australian entities, Thomson Reuters (Australia) Pty. Limited and Thomson Reuters (Professional) Australia Ltd., described there as indirect wholly owned subsidiaries of Thomson Reuters Corporation, an Ontario corporation listed on the Toronto and New York stock exchanges; that statement carries no ACN or ABN and does not say which entity contracts for Westlaw. The only contract documents published on the Australian site are a website terms of use and a ProView content licence agreement for e-books; the privacy statement linked from the Australian site is the global Thomson Reuters Privacy Statement, which has supplements for California, the EU/UK/Switzerland, China and US government data but no Australian supplement and no reference to the Privacy Act 1988 (Cth). Customers named: a testimonial on the product page is attributed to a partner at Henry William Lawyers referring to Westlaw Precision Australia and CoCounsel, and a testimonial on the Australian AI campaign page is attributed to a research lead at MinterEllison referring to Westlaw Precision and Search and Summarise in Practical Law. |

## What the research found

| Topic | Status | Finding | Open question | Sources |
| --- | --- | --- | --- | --- |
| Which tier this covers and how it differs from the sibling tier | Public claim only | The product page presents Westlaw Precision Australia as the Australian legal research platform combining Thomson Reuters' Australian content with generative AI, and lists five advanced features: AI-Assisted Research, Litigation Document Analyser, KeyCite Cited With, Outline Builder, and Keep list / Hide details (read 2026-09-27). The Westlaw Advantage Australia FAQ states both tiers 'provide accurate and trusted answers to your legal questions based on expert legal content' while Advantage 'takes things a step further by employing agentic AI to conduct multistep processes without being prompted'. Both tiers are live and separately marketed as at 2026-09-27; this is not a former name of the Advantage tier. Whether Precision is a separate SKU or an uplift on Westlaw Australia is not published. | On our order form, is Westlaw Precision Australia a separate subscription or an uplift on Westlaw Australia, is it being superseded by Westlaw Advantage Australia, and what happens to our Precision entitlements if it is? | [Westlaw Precision Australia - product page, advanced features and FAQ, including the Retrieval Augmented Generation statement and the vendor's verification caveat](https://www.thomsonreuters.com.au/en-au/products/westlaw-precision-australia.html); [Westlaw Advantage Australia - product overview and FAQ, including the vendor's answer on the difference between the Advantage and Precision tiers](https://www.thomsonreuters.com.au/en-au/products/westlaw-advantage-australia.html) |
| Release stage and Australian launch date | Not confirmed | The five features are presented as available with no beta or preview labelling (read 2026-09-27). No press release or dated release note establishing the Australian launch date of AI-Assisted Research was read. A cached Thomson Reuters Australia products index carries the line 'Legal research will take a leap forward in July 2024 as generative AI combines with Australia's most trusted legal database', which points to a July 2024 Australian availability date but is marketing copy rather than a dated release note, so the date is not recorded as established. | State the Australian general-availability date of AI-Assisted Research and of Litigation Document Analyser on this tier, and give us the release notes channel we will be subscribed to. | [Westlaw Precision Australia - product page, advanced features and FAQ, including the Retrieval Augmented Generation statement and the vendor's verification caveat](https://www.thomsonreuters.com.au/en-au/products/westlaw-precision-australia.html); [Westlaw Advantage Australia - product overview and FAQ, including the vendor's answer on the difference between the Advantage and Precision tiers](https://www.thomsonreuters.com.au/en-au/products/westlaw-advantage-australia.html) |
| What the AI features are described as doing | Public claim only | AI-Assisted Research is described as 'the generative AI grounded in trusted primary law content, including all the Authorised Law Reports': the user asks a conversational question and receives AI-generated summaries that can be validated 'with in-line links to original sources'. Litigation Document Analyser is described as 'using AI to verify legal research and ensure all references are accurate and complete'. KeyCite Cited With is described as identifying frequently cited cases relevant to the research 'even if each case doesn't directly cite the other'. Outline Builder and Keep list / Hide details are described as non-AI research tools (drag-and-drop outlines, bookmarking up to 50 documents, hiding reviewed documents). All read 2026-09-27 on the vendor's own page; none is independently measured, and the Litigation Document Analyser description on this page is one sentence shorter and less specific than the description of the feature of the same name on the Advantage features page. | Demonstrate AI-Assisted Research and Litigation Document Analyser on our own questions and drafts, and tell us whether the Litigation Document Analyser on this tier is the same feature as the one described on the Westlaw Advantage features page or a narrower version. | [Westlaw Precision Australia - product page, advanced features and FAQ, including the Retrieval Augmented Generation statement and the vendor's verification caveat](https://www.thomsonreuters.com.au/en-au/products/westlaw-precision-australia.html); [Westlaw Advantage Australia - product overview and FAQ, including the vendor's answer on the difference between the Advantage and Precision tiers](https://www.thomsonreuters.com.au/en-au/products/westlaw-advantage-australia.html) |
| Deployment model | Public claim only | The product is presented only as a hosted platform reached through the vendor's site, with a demo request and a contact form as the routes to buy (read 2026-09-27). No private cloud, on-premises or self-hosted option is published, and no hosting region is stated. | Confirm there is no deployment option other than your multi-tenant cloud for this tier, and name the cloud provider and region that serves Australian subscribers. | [Westlaw Precision Australia - product page, advanced features and FAQ, including the Retrieval Augmented Generation statement and the vendor's verification caveat](https://www.thomsonreuters.com.au/en-au/products/westlaw-precision-australia.html); [Westlaw Australia plan options - Thomson Reuters Australia store](https://store.thomsonreuters.com.au/products/westlaw/plan-options.aspx) |
| Australian legal content and currency | Public claim only | The page states coverage of authorised law reports for the High Court, the Federal Court, the Fair Work Commission and state superior courts, The Laws of Australia across 320-plus topics and every Australian jurisdiction, the Australian Law Journal, and Australian Commercial, NSW and Victorian precedents, across 21 practice areas, and states AI-Assisted Research is grounded in primary law content 'including all the Authorised Law Reports' (read 2026-09-27). No update interval is published for any collection, and the store sells practice areas and law reports as add-ons, so coverage depends on the plan. | Which Australian collections will be in our licence, what is the publication lag for each, and does AI-Assisted Research answer only from the collections we license? | [Westlaw Precision Australia - product page, advanced features and FAQ, including the Retrieval Augmented Generation statement and the vendor's verification caveat](https://www.thomsonreuters.com.au/en-au/products/westlaw-precision-australia.html); [Westlaw Australia plan options - Thomson Reuters Australia store](https://store.thomsonreuters.com.au/products/westlaw/plan-options.aspx) |
| How the tier is licensed and charged | Public claim only | The Thomson Reuters Australia store publishes Westlaw Australia plans for 1-3 practitioners (Essentials from $133 per month and Essentials plus 2 Practice Areas from $340 per month, each a 12-month subscription for one practitioner, with a 30-day guarantee) and a quote-based Enterprise plan for organisations with 4 or more practitioners including law firms, bar chambers, government, courts and academic institutions; add-on content is bought as an add-on subscription or pay-per-view once Essentials is held (read 2026-09-27). Neither the store page nor the product page states a price or a licence metric for the Precision tier. Unverified, not applied (2026-10-10): pricing claim From $133 per month12 month subscription for 1 practitioner (https://store.thomsonreuters.com.au/products/westlaw/plan-options.aspx). not a price for this product. Unverified, not applied (2026-10-10): pricing claim From $340 per month12 month subscription for 1 practitioner (https://store.thomsonreuters.com.au/products/westlaw/plan-options.aspx). not a price for this product. | Quote Westlaw Precision Australia for year one and year two: the licence metric, user minimum, any cap on AI-Assisted Research queries or Litigation Document Analyser uploads, and the renewal uplift. | [Westlaw Australia plan options - Thomson Reuters Australia store](https://store.thomsonreuters.com.au/products/westlaw/plan-options.aspx); [Westlaw Precision Australia - product page, advanced features and FAQ, including the Retrieval Augmented Generation statement and the vendor's verification caveat](https://www.thomsonreuters.com.au/en-au/products/westlaw-precision-australia.html) |
| Connected products | Public claim only | The product page states the tier connects with 'other leading AI solutions like CoCounsel, Practical Law and Microsoft 365 CoPilot' (read 2026-09-27). The Australian AI campaign page states Thomson Reuters AI connects to 'Westlaw Precision, Practical Law, Microsoft 365, and DMS partners like iManage, netdocuments and more'; the DMS statement is made about the portfolio rather than about this tier. The CoCounsel Australia page lists Westlaw Precision Australia as a related product. No integration documentation, permission model or configuration guide was found for this tier. | For Westlaw Precision Australia specifically, what does the Microsoft 365 Copilot connection do, what content passes between the two, and is a document-management integration included or separately licensed? | [Westlaw Precision Australia - product page, advanced features and FAQ, including the Retrieval Augmented Generation statement and the vendor's verification caveat](https://www.thomsonreuters.com.au/en-au/products/westlaw-precision-australia.html); [Thomson Reuters Australia - AI campaign page ('Professional-grade AI'), including the ISO/IEC 42001 statement for Westlaw and CoCounsel](https://www.thomsonreuters.com.au/en-au/c/ai-lawyers-trust.html); [CoCounsel (Australia) - product page and FAQ, including training, retention, encryption and Australian residency answers](https://www.thomsonreuters.com.au/en-au/products/cocounsel.html) |
| Australian support | Not confirmed | No support hours, severity matrix, service-level commitment or security contact for Westlaw Precision Australia was found on the product page, the store pages or the Australian terms of use (all read 2026-09-27). The CoCounsel Australia page claims 'a local team of AI and legal specialists'. Thomson Reuters Australia publishes support and product-training pages, which were not read. | Give us the Australian support hours, severity definitions and response times for Westlaw Precision Australia, and the address for security and privacy notices on our account. | [Westlaw Precision Australia - product page, advanced features and FAQ, including the Retrieval Augmented Generation statement and the vendor's verification caveat](https://www.thomsonreuters.com.au/en-au/products/westlaw-precision-australia.html); [Westlaw Australia plan options - Thomson Reuters Australia store](https://store.thomsonreuters.com.au/products/westlaw/plan-options.aspx); [CoCounsel (Australia) - product page and FAQ, including training, retention, encryption and Australian residency answers](https://www.thomsonreuters.com.au/en-au/products/cocounsel.html) |
| What the vendor offers as evidence of quality | Public claim only | The FAQ sets out an architectural statement rather than a measurement: 'Westlaw Precision Australia employs a Retrieval Augmented Generation (RAG) approach, grounding the Large Language Model (LLM) in Thomson Reuters' content when generating a response. Responses include source citations, enhancing transparency and allowing users to easily verify the underlying language supporting the response.' The same answer records the vendor's own caveat to 'still conduct additional verification and follow-up research as you would with a skilled trainee or paralegal assisting you today' (read 2026-09-27). The Australian AI campaign page adds '2.6x' on document review and contract drafting and '85%' of users finding more key information, footnoted to 'Thomson Reuters customer surveys and U.S. usage data, 2024'. The CoCounsel Australia FAQ describes a Trust Team running over 1,500 automated tests nightly, stated for CoCounsel. No Australian-corpus evaluation, error rate or citation-accuracy measurement for AI-Assisted Research was found. The page's superlative claims about the database and about which AI to choose are the vendor's own characterisations and are not carried into this record as findings. | Provide measured citation-accuracy and error-rate results for AI-Assisted Research on Australian law, and let us run a trial on our own questions with the citations checked against KeyCite. | [Westlaw Precision Australia - product page, advanced features and FAQ, including the Retrieval Augmented Generation statement and the vendor's verification caveat](https://www.thomsonreuters.com.au/en-au/products/westlaw-precision-australia.html); [Thomson Reuters Australia - AI campaign page ('Professional-grade AI'), including the ISO/IEC 42001 statement for Westlaw and CoCounsel](https://www.thomsonreuters.com.au/en-au/c/ai-lawyers-trust.html); [CoCounsel (Australia) - product page and FAQ, including training, retention, encryption and Australian residency answers](https://www.thomsonreuters.com.au/en-au/products/cocounsel.html) |
| What the published description supports | Public claim only | On the published description the output is an AI-generated summary answering a conversational question, with in-line links to the source documents, plus a check of references in a draft. Both are intermediate work product that a lawyer must verify: the vendor's own FAQ says so. Whether this suits a given task in a given firm is a judgement that firm makes on its own evidence; nothing published here settles it. | For each task we name, show a worked Australian example end to end, including what the in-line links resolve to and what the product does when the licensed collections do not answer the question. | [Westlaw Precision Australia - product page, advanced features and FAQ, including the Retrieval Augmented Generation statement and the vendor's verification caveat](https://www.thomsonreuters.com.au/en-au/products/westlaw-precision-australia.html) |
| Checked for vendor content directing how AI describes the product | Not confirmed | Checked deliberately on 2026-09-27: the Westlaw Precision Australia page, the Westlaw Advantage Australia page, the Australian AI campaign page and the CoCounsel Australia page contain no section addressed to AI models, assistants, crawlers or LLMs, and no 'Instructions for AI Assistants' heading. A site map run over thomsonreuters.com.au on 2026-09-27 returned no /ai-info, /for-ai or llms.txt path, and no such URL was guessed at. | Do you publish any page or block of content that tells AI models, assistants or crawlers how to describe Westlaw Precision Australia? | [Westlaw Precision Australia - product page, advanced features and FAQ, including the Retrieval Augmented Generation statement and the vendor's verification caveat](https://www.thomsonreuters.com.au/en-au/products/westlaw-precision-australia.html); [Westlaw Advantage Australia - product overview and FAQ, including the vendor's answer on the difference between the Advantage and Precision tiers](https://www.thomsonreuters.com.au/en-au/products/westlaw-advantage-australia.html); [Thomson Reuters Australia - AI campaign page ('Professional-grade AI'), including the ISO/IEC 42001 statement for Westlaw and CoCounsel](https://www.thomsonreuters.com.au/en-au/c/ai-lawyers-trust.html); [CoCounsel (Australia) - product page and FAQ, including training, retention, encryption and Australian residency answers](https://www.thomsonreuters.com.au/en-au/products/cocounsel.html) |
| The product FAQ answers a comparative question with its own product | Public claim only | The product page's FAQ opens with the question 'Which AI is best for legal research?' and answers 'The best Al for legal research is Westlaw Precision Australia', closing with 'Westlaw Precision is the AI legal research tool to choose' (checked 2026-09-27). The page cites no comparison, test or measurement in support. The same page carries superlative claims about the underlying database. A firm weighing the vendor's other public statements should know that this FAQ is written as an answer to a comparative search question and is marketing content, not a contractual document or a measurement. | What comparison or measurement, if any, supports the FAQ's answer that this is the product to choose, and will you warrant any of the FAQ's statements in our agreement? | [Westlaw Precision Australia - product page, advanced features and FAQ, including the Retrieval Augmented Generation statement and the vendor's verification caveat](https://www.thomsonreuters.com.au/en-au/products/westlaw-precision-australia.html) |
| Client authority to put matter material into the product | Not confirmed | No matter-exclusion control, client-notification template or engagement-letter guidance for Westlaw Precision Australia was found on the product page, the Australian website terms of use or the Privacy Statement (all read 2026-09-27). The CoCounsel Australia FAQ states a customer's content and prompts 'remain yours to the extent you hold ownership rights' and that, subject to applicable law and Thomson Reuters' terms and conditions, the customer owns the outputs; it says nothing about the authority a firm needs before putting client material in. Litigation Document Analyser on this tier is described as verifying references in the firm's own research or documents, so the question is live even if AI-Assisted Research takes only a typed question. | Can we exclude named clients or matters from Litigation Document Analyser, does a typed research question ever carry client-identifying facts into your logs, and what wording do you recommend for Australian engagement letters? | [Westlaw Precision Australia - product page, advanced features and FAQ, including the Retrieval Augmented Generation statement and the vendor's verification caveat](https://www.thomsonreuters.com.au/en-au/products/westlaw-precision-australia.html); [CoCounsel (Australia) - product page and FAQ, including training, retention, encryption and Australian residency answers](https://www.thomsonreuters.com.au/en-au/products/cocounsel.html); [Thomson Reuters Australia - website terms of use](https://www.thomsonreuters.com.au/en-au/terms-of-use.html) |
| Which model answers a query | Not confirmed | The FAQ states that a Retrieval Augmented Generation approach grounds 'the Large Language Model (LLM)' in Thomson Reuters' content, but names neither the model nor its provider or version, and the page names no provider anywhere (read 2026-09-27). The CoCounsel Australia FAQ names OpenAI GPT and states Thomson Reuters' third-party AI partner is contractually prohibited from training on customer data. The 24 August 2026 press release states Thomson Reuters' own model, Thomson, is first deployed in Tabular Analysis in CoCounsel Legal, with plans to extend Thomson models across the portfolio. Which model serves AI-Assisted Research on this tier is not published and is not inferred here. | Name the model, provider, version and region behind AI-Assisted Research and Litigation Document Analyser on our subscription, and tell us whether the Thomson model will replace it and on what notice. | [Westlaw Precision Australia - product page, advanced features and FAQ, including the Retrieval Augmented Generation statement and the vendor's verification caveat](https://www.thomsonreuters.com.au/en-au/products/westlaw-precision-australia.html); [CoCounsel (Australia) - product page and FAQ, including training, retention, encryption and Australian residency answers](https://www.thomsonreuters.com.au/en-au/products/cocounsel.html); [Thomson Reuters launches its own frontier model, Thomson - press release, 24 August 2026](https://www.thomsonreuters.com.au/en-au/press-releases/2026/august/thomson-reuters-leverages-its-world-class-data-assets-to-launch-its-own-frontier-model.html) |
| Subprocessors and their locations | Not confirmed | No subprocessor list or schedule for Westlaw Precision Australia was found, and no subprocessor page exists on the Australian site (checked 2026-09-27, including a site map). The Privacy Statement (last updated 31 July 2026) says personal information may be shared with 'third-party service providers and partners that support our business, such as our content and other partners, vendors and subcontractors, analytics providers, advertising and marketing agencies, credit agencies, and other third parties we engage', naming none and giving no country; it also states it does not apply where Thomson Reuters acts as a processor for a customer. | Provide the dated subprocessor schedule for Westlaw Precision Australia including the model provider, each subprocessor's country, and the notice period and objection right when you add or change one. | [Thomson Reuters Privacy Statement (global statement linked from the Australian site), last updated 31 July 2026](https://www.thomsonreuters.com.au/en/privacy.html); [Westlaw Precision Australia - product page, advanced features and FAQ, including the Retrieval Augmented Generation statement and the vendor's verification caveat](https://www.thomsonreuters.com.au/en-au/products/westlaw-precision-australia.html) |
| Whether our queries and documents train or improve models | Not confirmed | Nothing on the Westlaw Precision Australia page says whether research questions or documents put through Litigation Document Analyser are used to train or improve any model (read 2026-09-27). The Privacy Statement lists 'the content of your queries on our Services, such as artificial intelligence prompts' among the personal information collected, and says some Services 'may use artificial intelligence, machine learning, automation, analytics, or similar technologies to provide, improve, personalize, secure, or support our Services'. The CoCounsel Australia FAQ states Thomson Reuters does not use customer content or prompts to train or enhance CoCounsel or any third-party LLM and that customer information is not stored by OpenAI GPT; that answer is about CoCounsel. The 24 August 2026 press release says customer data is not used to train the Thomson model 'without explicit consent'. | Warrant in our agreement that our AI-Assisted Research questions and any documents we submit are not used to train, fine-tune, evaluate or improve any Thomson Reuters or third-party model, including embeddings and evaluation sets, and tell us what 'explicit consent' to train the Thomson model would look like on our account. | [Westlaw Precision Australia - product page, advanced features and FAQ, including the Retrieval Augmented Generation statement and the vendor's verification caveat](https://www.thomsonreuters.com.au/en-au/products/westlaw-precision-australia.html); [Thomson Reuters Privacy Statement (global statement linked from the Australian site), last updated 31 July 2026](https://www.thomsonreuters.com.au/en/privacy.html); [CoCounsel (Australia) - product page and FAQ, including training, retention, encryption and Australian residency answers](https://www.thomsonreuters.com.au/en-au/products/cocounsel.html); [Thomson Reuters launches its own frontier model, Thomson - press release, 24 August 2026](https://www.thomsonreuters.com.au/en-au/press-releases/2026/august/thomson-reuters-leverages-its-world-class-data-assets-to-launch-its-own-frontier-model.html) |
| Usage data, feedback ratings and evaluation sets | Not confirmed | Nothing is published for Westlaw Precision Australia. The CoCounsel Australia FAQ states Thomson Reuters 'analyses de-identified usage metrics to monitor account health, forecast capacity needs, and inform the product roadmap' without defining de-identified, and separately that a Trust Team compares CoCounsel outputs to expert-crafted answers and uses those results 'to train an LLM for ongoing automated evaluations'. No statement was found about what happens to a rating a user gives an AI-Assisted Research answer (all read 2026-09-27). | Can our question text or answer text appear in de-identified usage data or in the evaluation sets used to train your evaluation model, and is a feedback rating stored with the underlying question? | [CoCounsel (Australia) - product page and FAQ, including training, retention, encryption and Australian residency answers](https://www.thomsonreuters.com.au/en-au/products/cocounsel.html); [Westlaw Precision Australia - product page, advanced features and FAQ, including the Retrieval Augmented Generation statement and the vendor's verification caveat](https://www.thomsonreuters.com.au/en-au/products/westlaw-precision-australia.html) |
| How long questions, answers and submitted documents are kept | Not confirmed | No retention period is published for Westlaw Precision Australia (checked 2026-09-27). The Privacy Statement says personal information is retained under an enterprise records retention schedule that 'varies by Service, business function, country, record classes, and record types' and states no period. The CoCounsel Australia FAQ says retention of user content and prompts is configurable at organisation level with a Thomson Reuters client manager; whether that setting reaches research history on this tier is not published. Backups are addressed nowhere. | State the retention period that will apply to our research questions, AI-generated answers, saved outlines and any documents submitted to Litigation Document Analyser, including logs and backups, and whether we can set it to zero retention. | [Thomson Reuters Privacy Statement (global statement linked from the Australian site), last updated 31 July 2026](https://www.thomsonreuters.com.au/en/privacy.html); [CoCounsel (Australia) - product page and FAQ, including training, retention, encryption and Australian residency answers](https://www.thomsonreuters.com.au/en-au/products/cocounsel.html); [Westlaw Precision Australia - product page, advanced features and FAQ, including the Retrieval Augmented Generation statement and the vendor's verification caveat](https://www.thomsonreuters.com.au/en-au/products/westlaw-precision-australia.html) |
| Deletion on request and certification | Not confirmed | No in-product deletion or certified-deletion statement was found for Westlaw Precision Australia (checked 2026-09-27). The CoCounsel Australia FAQ says users can delete their own content and prompts in the product at any time. The Privacy Statement's access, correction and erasure rights are framed around personal information and exercised through a data subject rights portal, not as a commitment about research history or matter documents held as processor. | Can a user delete their research history and any submitted document from Westlaw Precision immediately and irreversibly, how long do copies persist in backups and at any subprocessor, and will you certify deletion in writing? | [Thomson Reuters Privacy Statement (global statement linked from the Australian site), last updated 31 July 2026](https://www.thomsonreuters.com.au/en/privacy.html); [CoCounsel (Australia) - product page and FAQ, including training, retention, encryption and Australian residency answers](https://www.thomsonreuters.com.au/en-au/products/cocounsel.html) |
| Who can read our questions and documents | Not confirmed | The CoCounsel Australia FAQ states that, where applicable, Thomson Reuters has 'established systemic controls to turn off third parties' abuse-monitoring solutions to ensure there is no human access to Thomson Reuters customers' data', and that requests to model providers are sent under the 'Thomson Reuters' identity without identifying the customer; that is stated for CoCounsel. Nothing is published about which Thomson Reuters staff or contractors can read Westlaw Precision research questions, answers or submitted documents, whether such access is logged, or which countries support staff work from. The Privacy Statement's only geographic statement is that personal information 'may be stored in and accessed from multiple countries, including the United States'. All read 2026-09-27. | Who at Thomson Reuters or its contractors can read our research questions and any submitted documents, in which countries do they sit, is each access logged, and will you give us the log on request? | [CoCounsel (Australia) - product page and FAQ, including training, retention, encryption and Australian residency answers](https://www.thomsonreuters.com.au/en-au/products/cocounsel.html); [Thomson Reuters Privacy Statement (global statement linked from the Australian site), last updated 31 July 2026](https://www.thomsonreuters.com.au/en/privacy.html) |
| Identity, single sign-on and deprovisioning | Not confirmed | No SAML or single sign-on, multi-factor authentication or SCIM provisioning documentation for Westlaw Precision Australia was found on the product page, the store pages or the Australian terms of use (checked 2026-09-27). The store's self-service purchase flow creates a Westlaw Australia account from user details entered at purchase. The Australian terms of use contains no account security clause. | Does our tier support SAML single sign-on, enforced multi-factor authentication and SCIM deprovisioning, can AI-Assisted Research be restricted by role, and how quickly does a departing lawyer lose access to saved research? | [Westlaw Precision Australia - product page, advanced features and FAQ, including the Retrieval Augmented Generation statement and the vendor's verification caveat](https://www.thomsonreuters.com.au/en-au/products/westlaw-precision-australia.html); [Westlaw Australia plan options - Thomson Reuters Australia store](https://store.thomsonreuters.com.au/products/westlaw/plan-options.aspx); [Thomson Reuters Australia - website terms of use](https://www.thomsonreuters.com.au/en-au/terms-of-use.html) |
| Encryption in transit and at rest | Not confirmed | Nothing product-specific is published (checked 2026-09-27). The Privacy Statement says Thomson Reuters 'work[s] to implement technical and organizational measures designed to protect the security of personal information' and that no method of transmission or electronic storage is completely secure; it names no algorithm and says nothing about key management. The CoCounsel Australia FAQ states data is encrypted in transit using TLS 1.2 and at rest with AES 256 and that all interactions with generative AI model providers use zero-retention APIs; those statements are about CoCounsel. | Confirm in writing the in-transit and at-rest encryption applied to Westlaw Precision research questions, answers and submitted documents, whether it covers logs, search indexes and backups, and whether the model calls use a zero-retention endpoint. | [Thomson Reuters Privacy Statement (global statement linked from the Australian site), last updated 31 July 2026](https://www.thomsonreuters.com.au/en/privacy.html); [CoCounsel (Australia) - product page and FAQ, including training, retention, encryption and Australian residency answers](https://www.thomsonreuters.com.au/en-au/products/cocounsel.html) |
| Certifications and assessments, and their scope | Public claim only | The product page carries a badge stating 'Thomson Reuters achieves ISO 42001 certification for Responsible AI' with the sentence 'We are committed to responsible AI development, risk management, and ethical decision-making' (read 2026-09-27). The Australian AI campaign page states the ISO/IEC 42001:2023 certification was achieved 'for Westlaw and CoCounsel'. The CoCounsel Australia page adds that CoCounsel (Australia) was IRAP assessed on 22 June 2026 against PROTECTED classification level controls, naming CoCounsel only. No certificate, certifying body, scope statement, SOC 2 report, ISO 27001 certificate or IRAP letter was read, and the badge is stated at Thomson Reuters level rather than evidenced for this product. The Privacy Statement's only named regime is US FedRAMP Moderate 'In Process' status on certain products, which concerns US government hosting. ISO 42001: the vendor's own page states "aw-precision-australia/demo.html) AAR ![](https://play.vidyard.com/T8twY9UmdJekvcr4mTZBNL.jpg) ![ISO42001](https://www.thomsonreuters.com.au/en-au/products/westlaw-precision-australia/_" (https://www.thomsonreuters.com.au/en-au/products/westlaw-precision-australia.html, checked 2026-10-10).

| Contract, data processing terms and governing law | Not confirmed | No subscription agreement, master terms or data processing addendum for Westlaw Precision Australia is published. The only contract documents found on the Australian site are a website terms of use, which governs use of the website only, states 'We may amend the Terms at any time by posting the amended terms on this site', disclaims all warranties on an 'as is' and 'as available' basis, and contains no governing-law, forum or liability provision for a product subscription, and a ProView content licence agreement for e-books; a site map run over thomsonreuters.com.au on 2026-09-27 returned no other Australian product terms. The CoCounsel Australia FAQ refers to 'Thomson Reuters' terms and conditions' without linking them. | Send the Westlaw Precision Australia subscription agreement and data processing addendum, naming the contracting Thomson Reuters entity and its ACN, the governing law and forum, the liability cap, and how liability is allocated for a wrong or fabricated citation in an AI-Assisted Research answer. | [Thomson Reuters Australia - website terms of use](https://www.thomsonreuters.com.au/en-au/terms-of-use.html); [CoCounsel (Australia) - product page and FAQ, including training, retention, encryption and Australian residency answers](https://www.thomsonreuters.com.au/en-au/products/cocounsel.html); [Westlaw Australia plan options - Thomson Reuters Australia store](https://store.thomsonreuters.com.au/products/westlaw/plan-options.aspx); [Westlaw Precision Australia - product page, advanced features and FAQ, including the Retrieval Augmented Generation statement and the vendor's verification caveat](https://www.thomsonreuters.com.au/en-au/products/westlaw-precision-australia.html) |
| Where the data goes, and whether inference runs in Australia | Not confirmed | No hosting region, processing location or Australian data residency statement was found for Westlaw Precision Australia (checked 2026-09-27), and none is inferred from the product's Australian branding or its .com.au address. Two published statements bear on it and neither is about this tier: the Privacy Statement says personal information 'may be transferred outside of your home country and may be stored in and accessed from multiple countries, including the United States', asks the user to acknowledge the risk of transfer to countries with weaker protection and says Thomson Reuters 'may not be able to prevent government authorities in some countries from accessing your personal information'; the CoCounsel Australia FAQ says that for CoCounsel Core 'all customer prompts, content, and output are currently stored and processed in Australia', qualified by the word 'currently'. | List every country in which Westlaw Precision Australia questions, answers, submitted documents, logs, backups and support access are processed, state whether inference for AI-Assisted Research runs in Australia, and put any Australian residency commitment in the contract rather than an FAQ. | [Thomson Reuters Privacy Statement (global statement linked from the Australian site), last updated 31 July 2026](https://www.thomsonreuters.com.au/en/privacy.html); [CoCounsel (Australia) - product page and FAQ, including training, retention, encryption and Australian residency answers](https://www.thomsonreuters.com.au/en-au/products/cocounsel.html); [Westlaw Precision Australia - product page, advanced features and FAQ, including the Retrieval Augmented Generation statement and the vendor's verification caveat](https://www.thomsonreuters.com.au/en-au/products/westlaw-precision-australia.html) |
| Security incident notification | Not confirmed | No breach or security-incident notification commitment, timeline or notice address for Westlaw Precision Australia was found (checked 2026-09-27). The Privacy Statement contains no incident-notification clause and the Australian website terms of use contains none. No incident history is published. | What contractual notice period applies from your discovery of a security incident affecting our Westlaw Precision data, who is notified and how, and will you give us a summary of incidents affecting the platform over the last 24 months? | [Thomson Reuters Privacy Statement (global statement linked from the Australian site), last updated 31 July 2026](https://www.thomsonreuters.com.au/en/privacy.html); [Thomson Reuters Australia - website terms of use](https://www.thomsonreuters.com.au/en-au/terms-of-use.html) |
| Notice of changes to the product, the model or the terms | Public claim only | The published change mechanics are unilateral. The Australian website terms of use states 'We may amend the Terms at any time by posting the amended terms on this site.' The Privacy Statement states 'We reserve the right to update it at any time for any reason', with notice given by updating the last-updated date and posting the revised statement. The Australian AI campaign page says customers 'Continually benefit from the latest breakthroughs in legal AI, with automatic access to new capabilities as they become available'. No notice period for a change of model, retrieval behaviour or processing location was found, and the 24 August 2026 press release shows the model layer under active change. All read 2026-09-27. | What written notice will we get before the model or the retrieval behaviour behind AI-Assisted Research changes, or before this tier is superseded by Westlaw Advantage, and can we decline a change or terminate without penalty? | [Thomson Reuters Australia - website terms of use](https://www.thomsonreuters.com.au/en-au/terms-of-use.html); [Thomson Reuters Privacy Statement (global statement linked from the Australian site), last updated 31 July 2026](https://www.thomsonreuters.com.au/en/privacy.html); [Thomson Reuters Australia - AI campaign page ('Professional-grade AI'), including the ISO/IEC 42001 statement for Westlaw and CoCounsel](https://www.thomsonreuters.com.au/en-au/c/ai-lawyers-trust.html); [Thomson Reuters launches its own frontier model, Thomson - press release, 24 August 2026](https://www.thomsonreuters.com.au/en-au/press-releases/2026/august/thomson-reuters-leverages-its-world-class-data-assets-to-launch-its-own-frontier-model.html) |
| Export and what happens on termination | Not confirmed | No export format, post-termination data window or deletion-on-exit term for Westlaw Precision Australia was found (checked 2026-09-27). The store describes 12-month subscriptions with a 30-day guarantee and add-on content bought as add-on subscriptions or pay-per-view, with no termination or data-return terms. Outline Builder and Keep list hold the firm's own research work product inside the platform, which makes export the live question on exit. | On termination, how do we export saved research, outlines, keep lists and AI-generated answers and in what format, what is deleted from Thomson Reuters and its subprocessors and within how many days, and will you certify it? | [Westlaw Australia plan options - Thomson Reuters Australia store](https://store.thomsonreuters.com.au/products/westlaw/plan-options.aspx); [Westlaw Precision Australia - product page, advanced features and FAQ, including the Retrieval Augmented Generation statement and the vendor's verification caveat](https://www.thomsonreuters.com.au/en-au/products/westlaw-precision-australia.html) |
| Connectors and what leaves our systems | Public claim only | The product page states connections with CoCounsel, Practical Law and Microsoft 365 Copilot (read 2026-09-27). The Australian AI campaign page states Thomson Reuters AI connects to Microsoft 365 and 'DMS partners like iManage, netdocuments and more', a portfolio statement rather than a connector list for this tier. No connector permission model, no statement of what content is copied out of a source system and no administrator control over connectors was found for Westlaw Precision Australia. | For Westlaw Precision Australia, list each connector, what content passes in each direction, whether document-management or Microsoft 365 permissions are enforced at query time, and whether we can disable each connector by role. | [Westlaw Precision Australia - product page, advanced features and FAQ, including the Retrieval Augmented Generation statement and the vendor's verification caveat](https://www.thomsonreuters.com.au/en-au/products/westlaw-precision-australia.html); [Thomson Reuters Australia - AI campaign page ('Professional-grade AI'), including the ISO/IEC 42001 statement for Westlaw and CoCounsel](https://www.thomsonreuters.com.au/en-au/c/ai-lawyers-trust.html) |
| Whether anything reaches the open web | Public claim only | The FAQ states that a Retrieval Augmented Generation approach grounds the language model 'in Thomson Reuters' content when generating a response', with source citations (read 2026-09-27). The CoCounsel Australia FAQ states prompting guardrails confine generative outputs to vetted sources such as Thomson Reuters' own content databases 'and not the open internet'; that is stated for CoCounsel. Neither page states that no step of AI-Assisted Research or Litigation Document Analyser queries an open-web source, and neither describes what the product does when the licensed collections do not contain an answer. | Confirm in writing that no step of AI-Assisted Research or Litigation Document Analyser sends our question or document text to an open-web search engine or to any source outside the Westlaw collections we license, and show us the no-answer behaviour. | [Westlaw Precision Australia - product page, advanced features and FAQ, including the Retrieval Augmented Generation statement and the vendor's verification caveat](https://www.thomsonreuters.com.au/en-au/products/westlaw-precision-australia.html); [CoCounsel (Australia) - product page and FAQ, including training, retention, encryption and Australian residency answers](https://www.thomsonreuters.com.au/en-au/products/cocounsel.html) |
| What the product can do without a person | Public claim only | The published behaviour is question-and-answer over a content set plus reference checking; the vendor's own comparison with Westlaw Advantage states that the Advantage tier, not this one, 'employ[s] agentic AI to conduct multistep processes without being prompted', which distinguishes this tier as prompted rather than autonomous. Nothing describes this tier writing to, sending from or changing any other system, and no action catalogue or administrator control list is published. All read 2026-09-27. | Confirm that no Westlaw Precision feature can write to, send from or change a connected system - CoCounsel, Microsoft 365, a document management system - without a person clicking, and tell us what the Microsoft 365 Copilot connection is permitted to do. | [Westlaw Advantage Australia - product overview and FAQ, including the vendor's answer on the difference between the Advantage and Precision tiers](https://www.thomsonreuters.com.au/en-au/products/westlaw-advantage-australia.html); [Westlaw Precision Australia - product page, advanced features and FAQ, including the Retrieval Augmented Generation statement and the vendor's verification caveat](https://www.thomsonreuters.com.au/en-au/products/westlaw-precision-australia.html) |
| Verification and what the citations prove | Public claim only | The vendor states its own verification expectation in the FAQ on hallucinations: responses include source citations 'allowing users to easily verify the underlying language supporting the response', and 'It is important that you still conduct additional verification and follow-up research as you would with a skilled trainee or paralegal assisting you today' (read 2026-09-27). The product page separately describes validating AI-generated summaries 'with in-line links to original sources'. Citations and in-line links make verification possible; they do not establish that an answer is complete or that the cited passage supports the proposition, and the lawyer's duty to the court and the client is unaffected. | Show us Australian sample answers with pinpoint in-line links, show how negative treatment and currency are surfaced on each cited authority, and show what the product does when it cannot support a proposition from the licensed collections. | [Westlaw Precision Australia - product page, advanced features and FAQ, including the Retrieval Augmented Generation statement and the vendor's verification caveat](https://www.thomsonreuters.com.au/en-au/products/westlaw-precision-australia.html) |

## Notes

The capability record for this tier is solid and the architecture statement is unusually specific, but Australian contractual and security facts are not published for it, so most of the 20 critical controls end not_verified. Read today: the product page and its FAQ, the Westlaw Advantage Australia page (for the vendor's own comparison of the two tiers), the CoCounsel Australia page and FAQ, the Thomson Reuters Privacy Statement served on the Australian site, the Australian website terms of use, the Australian AI campaign page, the Australian modern slavery transparency statement, the Westlaw Australia store plan options, and the 24 August 2026 frontier-model press release; a site map run over thomsonreuters.com.au returned no other Australian product terms. NOT REACHED because it is not published anywhere found: any Westlaw Precision Australia subscription agreement, master terms or data processing addendum; a subprocessor list; the Australian contracting entity's ACN or ABN; the hosting region and whether inference runs in Australia for this tier; and the model or provider behind AI-Assisted Research, which the FAQ describes only as a large language model grounded in Thomson Reuters content. The Westlaw Precision Australia features page (features.html) was captured in the saved URL list but not scraped, and the ISO/IEC 42001 certificate and its scope statement were not read. Deliberately not inferred: the CoCounsel Australia FAQ statements on Australian storage and processing, no-training, zero-retention model APIs and TLS 1.2/AES-256 are answers about CoCounsel Core and are recorded as such, not carried across to this tier. Also unresolved: whether the Litigation Document Analyser named on both this page and the Advantage page is one feature available on two tiers or two implementations. Capability list updated 2026-09-27 when the controlled vocabulary was extended from 19 to 38 values: added citation-verification. Values already present were kept, because they remain true descriptions of what the product does. Recheck 2026-10-10: 4 claims left unverified and not applied. Confidence raised from low to medium on 2026-10-10 because a security or hosting quote on the vendor's own domain was applied.
