AI Ethics for Legal Professionals: Competence, Confidentiality, and Candor in the Age of AI

The American Bar Association and most state bars have begun issuing formal guidance on the professional responsibility implications of AI use in legal practice. Three rules are most directly implicated: Rule 1.1 (competence, including technological competence), Rule 1.6 (confidentiality of client information), and Rule 3.3 (candor toward the tribunal). Understanding how these rules apply to AI use is now a baseline professional responsibility for every licensed attorney.

Rule 1.1: The duty of technological competence

Comment 8 to Model Rule 1.1 states that competent practice includes keeping abreast of changes in the law and its practice, including the benefits and risks associated with relevant technology. This means attorneys who use AI tools in practice have an obligation to understand how those tools work, where they fail, and how to supervise their outputs. An attorney who submits an AI-generated brief with fabricated citations has not merely made an error — they have failed their duty of technological competence.

Rule 1.6: Confidentiality and AI tools

1. 1Client information entered into a public AI tool may be used to train the model or retained by the vendor
2. 2Many state bars have issued guidance that using a public AI tool with client data without informed consent may violate Rule 1.6
3. 3Enterprise AI tools with appropriate data processing agreements and no-training commitments offer a more defensible path
4. 4Some bars require client disclosure before any AI tool is used on their matter
5. 5Check your jurisdiction's specific guidance — it is evolving rapidly

Rule 3.3: Candor toward the tribunal

Some courts have begun requiring disclosure when AI is used in preparing filings. Rule 3.3 prohibits knowingly making false statements of law or fact to a tribunal. Submitting an AI-generated citation that the attorney has not verified — and that turns out to be fabricated — is a knowing false statement once the attorney has been put on notice that AI tools hallucinate. The safe practice: verify every citation, and follow any applicable court rules on AI disclosure.

The big idea: professional responsibility obligations do not pause for AI. Competence, confidentiality, and candor all apply — and courts are beginning to enforce them.
