Australian presenceYes — Local AI and legal specialist team claimed. AU FAQ states all customer prompts, content and output are stored and processed in Australia for CoCounsel Core. IRAP assessment 22 June 2026 at PROTECTED. Allens has been reported as adopting CoCounsel alongside another tool; that report was not re-verified on a Thomson Reuters page in this pass.

Product and intended use

Define the configuration, people, information and tasks being assessed.

Australian configuration versus other editions

Public claim only

The AU product page describes CoCounsel as integrating with Westlaw Advantage Australia, Practical Law Australia, HighQ and Microsoft 365. Outlook security FAQ is written for CoCounsel Core v2 and names OpenAI GPT and Google Gemini. US/global CoCounsel Legal pages must not be treated as the AU contract.

Ask: Which CoCounsel edition, Westlaw/Practical Law collections and add-ins are on our order form, and do Outlook/Word use the same AU Core processing path?

Australian hosting

Public claim only

AU FAQ: all customer prompts, content and output are currently stored and processed in Australia. That is a vendor statement about the current Core configuration, not a signed data-map covering add-ins, telemetry, backups, failover or support.

Ask: In the agreement, confirm AU storage and inference and list every exception for support, telemetry, backups, failover and Microsoft Graph transfers.

Skills and connected products

Public claim only

AU page: legal research intelligence grounded in Westlaw and Practical Law; Microsoft Word, Outlook, Teams, SharePoint and iManage logos; HighQ. Related product: Westlaw Precision Australia generative research. Exact skill list on the contracted SKU is not published as a schedule.

Ask: List enabled skills (research, drafting, timelines, comparison, deposition) and which are generally available in Australia.

Australian legal content

Public claim only

Westlaw Precision Australia describes generative research over Australia's legal database, including Commonwealth Law Reports, authorised reports of the High Court, Federal Court, Fair Work Commission and state superior courts, and The Laws of Australia across every Australian jurisdiction. Currency and KeyCite-equivalent behaviour must be confirmed for AI answers.

Ask: Which collections and jurisdictions are in our licence, and how does CoCounsel show currency and negative treatment on each citation?

Adoption and implementation

Record the practical work needed to introduce and maintain the software.

Licence and pricing

Not confirmed

No public CoCounsel seat price. Research-publisher generative layers are commonly bundled into Westlaw/Practical Law contracts. GTCs for the AU subscription were not inspected in this pass.

Ask: Itemise CoCounsel, Westlaw Advantage Australia, Practical Law and add-ins for year one and year two, including user minimums and renewal uplift.

Microsoft 365 and DMS

Public claim only

AU page shows Word, Outlook, Teams, SharePoint and iManage. Outlook FAQ: Microsoft Graph REST APIs transfer email content with first-use consent; permissions usually managed in Entra. Graph security of M365 does not by itself prove CoCounsel's destination permission boundary.

Ask: What Graph permissions are required, what leaves M365, where is it retained in Australia, and are matter restrictions enforced after transfer?

Local support

Public claim only

AU page claims a local team of AI and legal specialists. No public support SLA, security contact or Australian-hours matrix was found on that page.

Ask: Provide AU support hours, severity response times and the security notice address for our account.

Quality and human effort

Compare complete work at the required quality, including checking and correction.

Quality and hallucination testing

Public claim only

AU FAQ: Trust Team of lawyers runs 1,500+ tests nightly; prompting confined to vetted Thomson Reuters sources rather than the open internet. Vals Legal AI Report (Feb 2025) scored CoCounsel on four tasks (including Document Q&A 89.6% and summarisation 77.2%); that study was not an Australian-corpus trial. Stanford RegLab 2024 evaluated Westlaw AI-Assisted Research separately and found material hallucination rates on US legal questions.

Ask: Share Australian-content evaluation results for our edition and allow a trial on our de-identified documents with citation checking.

Task fit

Public claim only

Fit is strongest for research and document Q&A over subscribed Australian sources, summarisation and extraction. Court documents citing authority and affidavits remain lawyer-led. Open-web answering is described as off for GenAI outputs confined to vetted databases.

Ask: Map each of our tasks to a CoCounsel skill and show 'no source found' behaviour on Australian questions outside the licensed collections.

Data, controls and requirements

Compare the actual configuration with firm, client and jurisdiction requirements, supported by evidence.

Client authority

Not confirmed

No public matter-exclusion or client-facing disclosure template was found. Output ownership is claimed for the customer subject to TR terms. The firm still needs client authority to put matter data into a third-party processor.

Ask: Can we exclude named clients or matters, and what wording do you recommend for Australian engagement letters?

Model providers

Public claim only

AU FAQ refers to OpenAI GPT and zero-retention APIs under the Thomson Reuters identity. Outlook Core v2 FAQ names OpenAI GPT and Google Gemini and says content is not stored by those providers. Do not treat that as a complete, current, AU-specific model register.

Ask: Provide the current model and endpoint register for our AU Core and Outlook add-in, including region and ZDR contract scope.

Training

Public claim only

AU FAQ: Thomson Reuters does not use content or prompts to train or enhance CoCounsel or any third-party LLMs; the AI partner is contractually prohibited from training; abuse-monitoring is turned off where applicable. Outlook FAQ table: User Content, Prompts and AI Outputs are not used to train or to improve the product; Usage Information is used to improve the product but not to train. These are FAQ statements, not the signed DPA extract.

Ask: Point to the signed clause covering prompts, outputs, uploads and embeddings for our AU edition, including Outlook Graph transfers.

Deletion

Public claim only

Users can delete content and prompts in-product; organisation deletion follows the customer's schedule. Exit deletion, certification and subprocessor purge were not in the FAQ.

Ask: On termination, what is deleted from TR and subprocessors, within how many days, and will you certify including backups?

Human access at model providers

Public claim only

AU FAQ: systemic controls turn off third parties' abuse-monitoring so there is no human access to customer data at those providers. TR staff access for support is not described. Outlook FAQ: sensitive-data use cases may be escalated to a Model Ethics Committee internally.

Ask: Who at Thomson Reuters can read our prompts, is that logged, and is abuse-monitoring off for every AU endpoint we use?

Assurance

Public claim only

AU page: ISO/IEC 42001:2023 certification; IRAP assessed 22 June 2026 against PROTECTED classification-level controls for CoCounsel (Australia). Outlook FAQ: penetration testing in 2025 for the add-in. SOC 2 for the CoCounsel AU system was not stated on that page. Reports were not inspected.

Ask: Provide the IRAP letter of completion, ISO 42001 certificate scope, SOC 2 if held, and the 2025 pen-test summary for AU CoCounsel and Outlook.

Contract and DPA

Not confirmed

AU FAQ says outputs are owned by the customer subject to applicable law and Thomson Reuters terms. The master terms, DPA, liability cap and law/forum for the AU subscription were not inspected in this pass.

Ask: Provide the AU DPA, liability caps, governing law and output-ownership clause that will apply to our order.

Cross-border disclosure

Public claim only

AU FAQ asserts storage and processing of prompts, content and output in Australia. Outlook uses Microsoft Graph, which may involve Microsoft 365 processing under the customer's M365 tenancy (often Australia for AU firms, but not proven here). Model-provider region is not named beyond ZDR APIs.

Ask: List every country for inference, Graph, support and telemetry on our AU Core and Outlook configuration.

Product and model changes

Not confirmed

No contractual model-change notice was found. Skills and models can change under a research-publisher subscription.

Ask: What notice do we get before model, skill or processing-location changes, and can we decline a change?

Exit

Not confirmed

In-product deletion of content and prompts is described. Export formats, post-termination window and certified deletion were not.

Ask: How do we export prompts, outputs and audit logs, and what is deleted on exit including Graph-transferred mail?

Open web

Public claim only

AU FAQ: prompting guardrails confine GenAI outputs to vetted Thomson Reuters databases and not the open internet. That does not prove every skill or add-in is closed-corpus.

Ask: Confirm no skill in our licence sends prompts to the open web, including Outlook and any agent features.

Human review

Public claim only

Westlaw Precision AU: validate AI-generated summaries with in-line links to original sources. CoCounsel is described as surfacing sources and reasoning. Lawyer verification remains the firm's duty; TR's nightly tests are not a substitute.

Ask: Show Australian sample outputs with pinpoint citations and unsupported-answer behaviour for our tasks.
