EU-level rules also apply — Practice Direction HC 142 (signed 29 Jul 2026, in operation 1 Sep 2026) requires affidavits and witness statements to carry a declaration that generative AI was not used to generate substantive content, and expert reports either a no-substantive-use declaration or disclosure of AI use. The Court of Appeal in Guerin v O'Doherty [2026] IECA 48 (26 Mar 2026) had already set out five principles including disclosure of AI use.

Ireland moved from guidance to a binding court rule in 2026. High Court Practice Direction HC 142, in operation from 1 September 2026, requires independent human verification of every AI-assisted citation and a no-substantive-use declaration in affidavits and witness statements. The Judicial Council has issued judges' guidelines and the Law Society solicitors' guidance.
As of 2026-09-04, Ireland has 7 binding rules, official guidance in 8 categories, 0 proposals and 0 positions set only by case law across the 20 categories in the map. Binding rules cover disclosure of AI use in filings, duty to verify AI output, self-represented litigants, consumer AI legal services, horizontal AI statute, sanctions for AI misuse, mandatory AI training. In 2 categories we found nothing; in 3 the position is not yet determined.

The rules, category by category
PD HC 142: every AI-assisted citation or proposition must be independently verified by a human, and checking with another AI tool is expressly insufficient. Reinforced by the Judicial Council guidelines for judges and by the Law Society guidance v4.
PD HC 142 applies to litigants and parties as well as lawyers. Two 2026 Court of Appeal judgments concern self-represented litigants: Guerin v O'Doherty [2026] IECA 48 (Costello P; appeal dismissed, five principles laid down) and Von Geitz v Kelly [2026] IECA 29 (Allen J; submissions with 'a few non-existent cases', appeals dismissed, verification held to be the litigant's own responsibility).
The Solicitors Acts and the Legal Services Regulation Act 2015 reserve specified legal activities and are technology-neutral. No Irish ruling or regulation specific to consumer AI legal products found as of 4 September 2026.
The EU AI Act applies directly, with Annex III point 8(a) covering judicial-support AI; the Law Society guidance carries the Article 4 literacy duty into practice. Ireland's designation of national competent authorities was not verified against an official instrument in this pass.
PD HC 142 sets out the sanctions expressly: rejection of documents, adverse or personal costs orders, strike-out and referral to the regulator. Before it, the Court of Appeal dismissed both Guerin v O'Doherty [2026] IECA 48 and Von Geitz v Kelly [2026] IECA 29 on submissions containing non-existent authorities.
Article 4 of the EU AI Act binds Irish firms as deployers from 2 Feb 2025 and the Law Society guidance v4 tells firms to address it for staff. No mandatory AI CPD hours.
Judicial Council of Ireland, 'Guidelines for Judges: The Use of Generative Artificial Intelligence', dated June 2024 and published November 2025 as a living document: routine and administrative tasks only, verify all output, no confidential case material in public tools.
Judicial Council guidelines: AI must not be used to determine outcomes or draft judicial reasoning. Not a statute or court rule.
Law Society of Ireland guidance v4 (12 Nov 2025): client confidential information must not be entered into tools without adequate safeguards; the guidance lists suitable and unsuitable uses.
Law Society guidance v4 addresses competence and requires firms to meet the Article 4 EU AI Act literacy obligation for staff.
No dedicated supervision rule. The Law Society guidance puts responsibility on firms to set the AI literacy and control framework for staff; PD HC 142 makes the person signing the document responsible for verification.
Law Society guidance v4: solicitors should be transparent with clients about material AI use. No consent requirement.
Law Society of Ireland, 'Use of Generative AI: Guidance for the Legal Profession', version 4 dated 12 November 2025. No equivalent Bar of Ireland or LSRA document was verified in this pass.
Law Society guidance v4 addresses safeguards required before client information enters a tool; no dedicated Irish vendor due-diligence rule found.
No Irish rule on authenticating AI-generated or deepfake evidence. PD HC 142 regulates the preparation of witness statements and expert reports but does not address admissibility of AI-generated material as evidence.
No Irish rule, guidance or reported case on billing for AI-assisted work found as of 4 September 2026.
Not researched — no published Courts Service policy on institutional AI deployment identified before the search budget was exhausted.
Not researched — no Data Protection Commission guidance specific to AI in legal services was checked in this pass; the GDPR and the DPC's general AI work apply.
Not researched — no Irish arbitral institution AI rule identified.
