Summary

Maine has no formal or informal bar ethics opinion on attorney AI use, and neither the Maine Supreme Judicial Court nor the U.S. District Court for the District of Maine has issued AI-specific standing orders. Maine has separately enacted a consumer-facing AI chatbot disclosure law (10 M.R.S. § 1500-DD, effective September 23, 2025) that applies to law firms using AI in client-facing communications, and a state AI Task Force issued a 34-recommendation policy report in October 2025.

Carrier Implications

Maine does not require attorneys to carry malpractice insurance. Carriers including ALPS factor AI use into underwriting; the W.R. Berkley "absolute AI exclusion" (2025-2026 E&O filings) eliminates coverage for claims arising from AI use without a verification carve-back. The 2026-2027 renewal cycle is the practical moment many Maine firms will face AI underwriting questions.

Maine is among the minority of states with no formal or informal bar ethics guidance on attorney AI use as of 2026-04-23. The Maine Board of Overseers of the Bar and its Professional Ethics Commission have published no AI opinion, and no AI-specific standing orders exist for Maine state or federal courts. Maine attorneys remain bound by the existing Maine Rules of Professional Conduct, which apply fully to AI use, and ABA Formal Opinion 512 (July 2024) is the closest available interpretive framework.

Two adjacent Maine developments matter for firms. First, 10 M.R.S. § 1500-DD (effective September 23, 2025) requires any business using an AI chatbot in trade or commerce with a consumer to provide clear and conspicuous disclosure that the consumer is not engaging with a human, enforceable as a Maine Unfair Trade Practices Act violation. Maine law firms using AI chat widgets, intake assistants, or AI answering services with prospective or current clients must comply. Second, Governor Mills’s AI Task Force delivered a 34-recommendation policy report in October 2025.

Bottom line for a 5-50 attorney Maine firm: No Maine-specific AI ethics opinion or court order exists to follow. Firms should treat ABA Formal Opinion 512 as the current interpretive floor, document compliance with MRPC 1.1, 1.6, 1.4, 3.3, 5.1, and 5.3, and adopt a written AI use policy before the malpractice carrier begins underwriting questions at renewal.
