Our Take
This is regulatory clarification, not a new rule—the BSB is saying existing duties already cover AI misuse, which means the burden shifts to practitioners to prove they understand what they're deploying.
Why it matters
Barristers now face documented expectations around AI competence whether or not they use the tools themselves. The bar has set a compliance floor just as AI errors in legal work are surfacing in case law.
Do this week
Compliance: audit your AI use against Core Duty 7 (competent service) and document your risk assessment before the end of this month so you can demonstrate reasoned adoption, not reactive adoption.
The BSB closes the ambiguity gap
The Bar Standards Board released guidance mapping its Core Duties in the BSB Handbook to AI and technology use. The move responds to rising AI adoption across legal practice, recent cases flagging misuse risks, and the Ayinde v London Borough of Haringey judgment.
The guidance does not introduce new rules. Instead, it translates seven existing core duties into practical technology terms. Core Duty 7 (competent standard of work) now explicitly requires barristers to maintain sufficient technology and AI awareness, whether or not they adopt those tools. Core Duty 1 (you must observe your duties under the BSB Handbook) now covers proper IT systems and data governance.
The framework includes good-practice checkpoints: evaluate risks and benefits before deploying a tool; maintain basic AI literacy; ensure client confidentiality and data protection; recognise that opposing counsel and clients may use AI, and barristers must understand those implications; and detect potential errors in AI-generated submissions.
Ewen MacLeod, director of strategy, policy and insights at the BSB, framed the guidance as enabling adoption while preserving professional obligations. The regulator is not banning AI. It is saying the rules already constrain it.
Competence now includes things you don't use
This shifts the compliance burden. A barrister who ignores AI tools entirely still faces a duty to understand their risks and benefits. The judgment standard is no longer "did you use it well" but "did you make an informed decision about whether to use it at all."
The timing matters. Hallucinations in AI-generated legal submissions have already surfaced in courts (most visibly in the U.S.). The BSB is pre-emptively anchoring compliance to documented awareness, not just outcomes. A practitioner who can show they evaluated AI risks and made a deliberate choice—to adopt, avoid, or restrict use—has a defensible posture. One who cannot may face complaints on competence grounds alone.
Three steps this week
First, read the guidance as a compliance checklist, not a feature list. The BSB is not endorsing any AI tool. It is saying: if you use one, you must show you understood what it does, what it cannot do, and what your client data might be exposed to.
Second, document your technology choices. Write a brief statement for each AI tool you use or decline to use. Why did you evaluate it? What risks did you identify? What safeguards did you put in place? File this as part of your firm's records. If a complaint arises, you have a paper trail.
Third, flag AI-generated submissions from opposing counsel. The guidance calls out the need to detect errors in AI output. If you receive a brief or argument that smells synthetic, raise it early with your opponent or the court. The onus is now shared, but the regulator expects you to notice.
