Can lawyers use AI? The rules, explained.

Short answer: yes. Lawyers can — and increasingly do — use AI tools, including generative AI. What the rules require is not abstinence but competent, supervised, confidential use. Here is how the core duties map onto everyday AI practice.

The duty of competence (Model Rule 1.1)

ABA Model Rule 1.1 requires competent representation, and Comment 8 extends competence to "the benefits and risks associated with relevant technology." For AI, that means understanding — at a working level — what a tool does, where it fails, and how to check its output. You don't need to build models; you do need to know that a general-purpose chatbot can fabricate citations and that its training data has a cutoff.

Confidentiality (Model Rule 1.6)

Entering client information into a tool can be a disclosure. Before you paste anything sensitive, know where the data goes, whether it is used for training, and who can see it. Many enterprise and legal-specific tools offer no-training, contractual data-handling terms; consumer chatbots often do not. When in doubt, anonymize or get informed consent.

Supervision (Model Rules 5.1 and 5.3)

AI output is the work of a non-lawyer assistant in everything but name. Partners and supervising lawyers remain responsible for work produced with AI, just as they are for a paralegal's draft. That means review workflows, not blind trust.

Candor to the tribunal (Model Rule 3.3)

You are responsible for every authority you cite. Submitting AI-generated cases without verifying they exist — and stand for what you claim — can violate the duty of candor and Rule 11. (See our companion piece on AI hallucinations in legal filings.)

Reasonable fees (Model Rule 1.5)

If AI makes a task dramatically faster, billing as though it took the old number of hours raises fairness questions. The emerging norm: bill for the value and the verification, not for time the tool saved you.

A practical checklist

• Know the tool — its purpose, data handling, and failure modes.
• Protect the client — no confidential data into tools that train on or expose it.
• Verify everything — treat output as a first draft, never as authority.
• Supervise — a responsible lawyer signs off on AI-assisted work.
• Be transparent — with clients and, where required, the court.
