Maine AI Ethics Rules for Lawyers

No AI-specific instrument yet

This jurisdiction had issued no AI-specific ethics opinion, court rule, or formal guidance as of our last review. That does not make AI use ungoverned here: the existing rules of professional conduct — competence, confidentiality, supervision, and candor — apply to generative AI the way they apply to any other tool, and ABA Formal Opinion 512 is the reference point most bars borrow in the meantime. The breakdown below covers what that means in practice; the changelog will record the week anything official issues.

Two clean checks, one dated conclusion

Maine’s negative is double-sourced. First, the lawyer-regulation side: the Professional Ethics Commission, which issues Maine’s ethics opinions under the Board of Overseers of the Bar, has an opinions index that we inspected on July 1, 2026, and it runs through Opinion No. 228 without an artificial-intelligence entry. Second, the court side: the Maine Judicial Branch’s published rules and administrative orders came up clean through January 2026 in the same review. Put together, as of July 1, 2026 Maine had no AI-specific instrument for lawyers from either its bar-regulation apparatus or its courts, and both halves of that sentence carry inspection dates because the tracker treats undated negatives as rot waiting to happen, per the methodology.

An executive branch in motion

Maine is not ignoring AI; it is working on it from the wrong branch for our purposes. A state task force on artificial intelligence, an executive-branch body, delivered its report on October 31, 2025. Executive AI governance can shape procurement, agency practice, and public policy, but it does not reach the professional conduct of lawyers, so the report is adjacent context here, not an instrument. The same goes for the legislature’s chatbot statute: statutes about AI systems generally are law of the state, not law of lawyering, and this dataset counts only authority addressed to attorneys, the line the state comparison table holds nationwide. If Maine’s bench or bar converts any of this energy into something attorney-facing, it gets added the week the primary source verifies.

The per-courtroom caveat that survives every statewide negative

A statewide zero never means zero rules in the room. Maine judges retain authority over their own dockets, and nationally the chambers-level layer of AI orders is where requirements tend to appear first, which is why the court orders guide belongs in every Maine filing checklist and why the Ropes & Gray order tracker earns its place in our sources. Add the client-side duties that exist regardless of geography, and the practical Maine posture is nearly complete: verify before filing per the hallucination survey, analyze the tool before client data enters it per the confidentiality guide, and bill actual time per the fee ethics analysis.

A one-page Maine policy, and what would change this page

For an office-level answer, the supervision rules plus the policy template produce a defensible written policy in an afternoon, with ABA Formal Opinion 512 as the reasoning behind each control and the solo and small-firm starter as the lighter-weight version. Three developments would convert this page into a deep-dive: a Professional Ethics Commission opinion on AI, an AI provision in the Maine rules or administrative orders, or formal attorney-facing bar guidance. Each would be checked against its primary source before anything here changes, and the changelog records the conversion the week it happens.
