Fill-in declarations required by High Court Practice Direction HC 142 from 1 September 2026: the opening declaration for affidavits and witness statements, the expert report declaration, and the expert's disclosure of GenAI use.

## Key facts

- Kind: Court document. A document filed or served in a court or tribunal.
- Practice area: [Commercial Litigation & Dispute Resolution](https://ailawframework.com/precedents/commercial-litigation-and-dispute-resolution.md)
- Jurisdictions: Ireland
- AI level: Green. The tool writes the first draft inside a template you have already tested. You check it. Without that test, first drafting starts at Yellow.
- Law stated as at: 2026-11-07
- Status: Maintained. Checked on 2026-11-07 against the authority it cites, for Ireland.

## When to use it

Use in any High Court of Ireland proceeding for affidavits, witness statements and expert reports prepared on or after 1 September 2026. Other court documents need disclosure only where the Court directs (para 21), so keep a record of GenAI use in case the Court asks.

## How AI may be used

A tool may lay out the HC 142 statement and fill in facts the signer gives it. The signer decides what to say about the AI use and makes the checks the statement describes.

**AI may:**

- Insert the tool name, version and uses the signer has recorded
- Insert only a version of the statement that the rule or order provides and that matches the signer's account of AI use
- Check that the statement sits where the rule or order says it must

**AI must not:**

- Must not state that citations, quotations or facts were checked; only the signer can say that after doing it
- Must not describe the AI use more narrowly than the file record shows
- Must not put prompts, privileged material or confidential client information in the statement
- Must not generate the substantive content of a witness's evidence and then use the paragraph 27 declaration

**The lawyer checks:**

- The current HC 142 rule or order has been opened on the court's own site and matches the words used
- Every citation and quotation was checked by a person against an official or recognised source
- The statement is placed and signed as the rule requires, by the person the rule names
- Any expert GenAI use is disclosed in enough detail for the Court to assess reliability, independence and weight (para 30)
