Aipedia: Barristers
Barristers can use AI, but the BSB treats it as a tool governed by the existing Core Duties, so counsel remains personally responsible for every output. That matters because a self-employed barrister's errors fall on their own compulsory BMIF cover and their own regulatory record.
Part of: AI in Barristers
In short
The BSB's Guidance on the use of AI and Other Technologies, valid from 18 May 2026, applies the existing Core Duties and conduct rules to AI rather than creating new rules. The Bar Council's November 2025 considerations are expressly non-regulatory but say ultimate responsibility stays with the barrister. Ayinde and MS (Bangladesh) show that fictitious citations lead to wasted costs and BSB referral. Self-employed barristers must insure with BMIF on minimum terms of at least £500,000 each and every claim, and the closed list of permitted exclusions says nothing about AI.
Generative AI chatbots, legal research platforms with built-in AI features and transcription tools are now part of everyday practice at the Bar. Counsel use them to find and summarise authorities, produce first drafts of skeleton arguments, pleadings and opinions, condense trial bundles and transcripts, review disclosure, plan cross-examination and run chambers administration such as diaries and fee notes.
The BSB's guidance is frank about the limits. It says AI is "likely to generate false citations when asked a legal question", that errors go beyond citations to flawed reasoning and missed issues, and that outputs should be verified "via independent alternative sources" even when a legal-specific tool is used. Its sixth principle is a reminder that clients, instructing solicitors and opponents are using AI too, so counsel may be checking other people's AI output as well as their own.
| Body | Document | Status | Key points |
|---|---|---|---|
| Bar Standards Board | Guidance on the use of AI and Other Technologies, valid from 18 May 2026 | Regulator's guidance on existing Handbook duties | Six principles; free public tools "unlikely" to meet confidentiality conditions; agentic AI with "absolute caution"; verify outputs independently |
| Bar Council | considerations on generative AI for the Bar, updated 26 November 2025 | Not regulatory and not Handbook guidance | Ultimate responsibility stays with the barrister; hallucinations, bias, confidentiality, cyber security and IP risks |
| Courts | Judicial AI guidance (October 2025) and the CJC consultation on AI in court documents | Judicial guidance; CJC proposals pending | Proposed declaration for trial witness statements; no new rule for skeletons or statements of case where the responsible lawyer is named |
| Bar Standards Board | Minimum Terms of Cover for the Self-Employed Bar, from 1 July 2019 | Binding | £500,000 each and every claim; defence costs in addition; closed list of exclusions |
The BSB maps AI risk onto Core Duties CD1 to CD10 and onto specific rules: rC9 (not misleading the court, no unsupported contentions), rC15 (confidentiality), rC19 (transparency with clients), rC20 (personal responsibility), rC86 (AI treated as outsourcing), rC87 and rC89 (managing practice and chambers) and rC123 (Public Access). Our walkthrough of the BSB AI guidance sets these out rule by rule.
The leading case is R (Ayinde) v LB Haringey [2025] EWHC 1383 (Admin), decided by the Divisional Court on 6 June 2025. Judicial review grounds settled by a pupil barrister cited five fictitious cases. Wasted costs of £2,000 were ordered against counsel and against the law centre, the court found the contempt threshold met but did not pursue it, and counsel was referred to the BSB. At ¶9 the court said heads of chambers must take "practical and effective measures", and at ¶82 that guidance alone is not enough.
In MS (Bangladesh) [2025] UKUT 305 (IAC) a barrister who used a generative AI chatbot cited a non-existent case and was referred to the BSB. In Munir [2026] UKUT 81 (IAC) the Upper Tribunal said that uploading confidential documents to an open AI tool places them in the public domain. As at October 2026 we have not found a published BSB disciplinary tribunal outcome for AI misuse.
Data protection sits alongside all of these. Self-employed barristers are typically their own data controllers for the ICO's purposes, so the choice of tool, where it processes data and how long it keeps prompts are the barrister's own decisions. New UK GDPR rules on automated decision-making, inserted by the Data (Use and Access) Act 2025, came into force on 5 February 2026. On the consumer side, the Legal Services Board's June 2026 research found binding standards for AI legal tools "nearly nonexistent", and counsel may meet clients who arrive with AI-generated research of uncertain quality.
The BSB's PI page says anyone holding a self-employed practising certificate must be a member of BMIF and pay premiums promptly, with a waiver only for barristers practising solely in another jurisdiction and fully insured there. The minimum terms require cover of at least £500,000 each and every claim, with defence costs in addition, and allow only a closed list of exclusions. None of those exclusions refers to AI or technology, so in Apex's reading an AI exclusion is not available in the compulsory layer, although one could appear in top-up or excess cover bought on the open market.
Two gaps matter. BSB and other regulator fines are a permitted exclusion, and whether a wasted costs order is covered depends on the wording. The minimum terms also do not require first-party cyber cover. See barristers' PI and the BSB, whether BMIF covers AI mistakes and PI for AI-using professionals.
Apex arranges PI for barristers and sets of chambers. A broker can review any top-up cover above your BMIF layer, check how each layer treats AI-assisted work and look at chambers-level cover alongside it.
Yes. The BSB's guidance, valid from 18 May 2026, does not ban AI. It explains how the existing Core Duties apply: protect confidentiality, verify outputs through independent sources, be transparent with clients where AI materially affects the service, and keep your own professional judgement. Free public tools should be limited to the lowest-risk tasks.
The BSB minimum terms for the self-employed Bar contain a closed list of permitted exclusions and none of them mentions AI or technology. A negligence claim arising from AI-assisted work is therefore usually treated like any other claim, subject to the policy terms. Regulatory fines are excluded and wasted costs depend on the wording.
The BSB says tell clients where AI materially affects the nature or scope of the service (rC19); low-risk, non-sensitive use may not need disclosure. It notes judicial guidance says there is generally no reason a representative must refer to AI use before the court, depending on context. Always answer court or BSB enquiries honestly.
A pupil barrister settled judicial review grounds citing five cases that did not exist. The Divisional Court ordered £2,000 wasted costs against counsel and against the law centre, found the contempt threshold met but did not pursue it, and referred counsel to the BSB. It also called on heads of chambers to take practical and effective measures.
