Massachusetts: AI Ethics Guidance for Law Firms

Bottom line for a 5-50 attorney Massachusetts firm: No formal Massachusetts ethics opinion exists, but the SJC Standing Advisory Committee’s late-2025 finding that existing RPCs provide “ample guidance” means the competence, confidentiality, and supervision framework has applied all along, with no grace period. Two Superior Court sanctions cases in 15 months (Smith v. Farwell and Dastou v. Holmes) establish that Mass. R. Civ. P. 11 verification duties extend to AI-generated content. The biggest risk is personal Rule 11 exposure that standard LPL policies generally do not cover, compounded by Ch. 93H data security obligations when client data passes through AI tools.

Start with: a written AI use policy, a citation verification step before any court filing, and a vendor diligence record covering 201 CMR 17.00 data security.

What governs by default

No formal numbered ethics opinion on attorney use of generative AI has issued from the Massachusetts Bar Association or the Board of Bar Overseers. Massachusetts Rules of Professional Conduct apply directly. At the page level, the applicable-rules block carries the AI-relevance gloss; the rules themselves are not Massachusetts-AI-specific.

In late 2025, the SJC Standing Advisory Committee on the Rules of Professional Conduct found that existing Massachusetts RPCs provide “ample guidance” on attorney AI use and recommended no rule amendments. The committee left open the possibility of future revision. Firms cannot argue they were operating in a regulatory gap; existing competence (Rule 1.1), confidentiality (Rule 1.6), and supervision (Rules 5.1 and 5.3) rules have applied since the framework took effect.

Two BBO Office of Bar Counsel practice articles read on the question without creating new rules. “The Wild West of Artificial Intelligence” (Afton Pavletic, 2024) walks through Mass. RPC 1.1, 1.6, 5.1, and 5.3 in the AI context. A 2025 follow-up by Assistant Bar Counsel Heather L. LaVigne, listed on the BBO articles-on-ethics page, documents escalating sanctions for AI hallucinations. It reinforces that attorneys cannot disclaim responsibility for AI-generated content filed with a court. Both are educational, not binding.

ABA Formal Opinion 512 (July 2024) is persuasive but not endorsed by any Massachusetts authority; treat it as a reference point, not the operative standard.

What federal courts in Massachusetts require for AI use in filings

No D. Mass. district-wide AI standing order has been confirmed as of April 2026. The operative federal default is Fed. R. Civ. P. 11: factual contentions must have evidentiary support and legal contentions must be warranted. Individual judges may impose AI disclosure requirements through chambers practices or scheduling orders that are not separately published. At the opening of each new federal matter, firms should review the assigned judge’s individual standing orders and case management orders directly at mad.uscourts.gov.

What Massachusetts state courts require for AI use in filings

No statewide attorney-facing AI rule applies to Massachusetts state court filings (Superior Court, Appeals Court, or SJC). The SJC Interim Guidelines for Use of Generative AI were announced by Chief Justice Kimberly Budd in her December 2025 State of the Judiciary address. They govern court personnel only: judges, clerks, registers, recorders, employees, law clerks, interns, and contractors. The Guidelines permit GenAI for administrative tasks using only public information and prohibit tools that retain or train on entered information. They explicitly do not govern attorney conduct or require attorney AI disclosure in filings. Chief Justice Budd described them as “a modest first step,” signaling that attorney-facing rules may follow.

Has anyone been sanctioned for AI use in Massachusetts?

Smith v. Farwell, Massachusetts Lawyers Weekly No. 12-007-24 (Norfolk Super. Ct. Feb. 12, 2024). Associate Justice Brian A. Davis sanctioned plaintiff’s counsel $2,000 for filing three memoranda containing at least four wholly fictitious AI-generated case citations. Under Mass. R. Civ. P. 11 and Rule 7, the court held, all attorneys are obligated to know whether AI is being used in preparation of court papers, and to verify the truthfulness and accuracy of AI-generated content before filing. Reliance on unverified output produced by junior associates was treated as a Rule 5.1 supervision failure, not an excuse. As the court warned, “blind acceptance of AI-generated content by attorneys undoubtedly will lead to other sanction hearings in the future, but a defense based on ignorance will be less credible.” See Boston Globe coverage.

Dastou v. Holmes, Middlesex Super. Ct. Civ. Action No. 2381CV02212 (June 25, 2025). Justice Keren E. Goldenberg sanctioned attorney Samantha Kemp after she formatted model jury instructions using ChatGPT and produced output containing a fictitious legal concept, a fictitious case citation, and a footnote that did not support the cited proposition. Sanctions: mandatory completion of an MCLE online program on drafting jury instructions, and a prohibition on billing the client for time spent preparing the defective materials. Per the court: “any document filed with the court must be reviewed thoroughly to ensure accuracy and the protection of client interest.” The opinion noted that “overreliance on AI risks deskilling legal practitioners.”

What AI-related rules are pending in Massachusetts?

While leaving open the possibility of future RPC amendments as technology evolves, the SJC Standing Advisory Committee recommended none in late 2025. No Massachusetts legislation specific to attorney professional conduct and AI is pending. The SJC Interim Guidelines for court personnel are subject to revision per Chief Justice Budd’s December 2025 framing.

Operative now is the April 16, 2024 Massachusetts AG Advisory on AI. It applies Ch. 93A consumer protection law, Ch. 93H and 201 CMR 17.00 data security requirements, breach notification obligations, and G.L. Ch. 151B and 272 anti-discrimination law to “developers, suppliers, and users” of AI. Law firms handling client personal information through AI tools fall within “users.”

How do malpractice carriers in Massachusetts treat AI use?

No Massachusetts-specific dominant LPL carrier has published AI guidance the research note independently confirms. Substantive carrier-relevant signals come from the two Superior Court sanctions cases: Mass. R. Civ. P. 11 sanctions imposed personally on counsel are generally outside standard LPL coverage, and the Dastou no-billing remedy does not foreclose a separate malpractice claim if the underlying defective work harms the client. Under the AG Advisory, Ch. 93H exposure for client data entered into non-compliant AI tools may fall outside standard LPL policies and may require separate cyber coverage. Confirm coverage scope directly with the firm’s carrier.

What does my Massachusetts malpractice carrier ask about AI at renewal?

Massachusetts carriers have not, in materials the research note independently confirms, published the specific items they will request on AI-related applications. Substantively, the standard is set by the SJC Standing Advisory Committee finding (existing RPCs apply), the two Superior Court sanctions cases, and the AG Advisory’s data security overlay. Firms should be ready to produce a written AI use policy, citation verification records, training logs, vendor due diligence under 201 CMR 17.00, and an incident response procedure under Rules 3.3 and 1.4. Confirm specific application items directly with the carrier or broker.

What documentation should a Massachusetts firm keep on file?

Month one (foundational)

1. (Owner: managing partner + firm administrator) Written AI use policy (Mass. RPC 1.1, 1.6, 5.1, 5.3). Enumerate approved tools. Prohibit entering confidential client data into non-compliant platforms. Require human review before any AI-generated content is filed or sent to clients. Assign output-verification responsibility. Directly responsive to the supervision failures sanctioned in Smith v. Farwell and Dastou v. Holmes.
2. (Owner: litigation lead) Citation verification checklist for court filings (Mass. R. Civ. P. 11; Mass. RPC 3.3). Pre-filing step requiring independent verification of every case citation against Westlaw, Lexis, or equivalent, with the signing attorney attesting to accuracy. Smith v. Farwell makes this mandatory as a practical matter.
3. (Owner: matter lead attorney) Court-specific workflow check (Mass. R. Civ. P. 11; Fed. R. Civ. P. 11). For each new federal matter, review the assigned D. Mass. judge’s individual standing orders and case management orders for AI disclosure requirements; for state court matters, document that no statewide AI rule applies.

Months two and three (operational documentation)

1. (Owner: firm administrator + outside IT) Vendor review record (Mass. RPC 1.6; Ch. 93H; 201 CMR 17.00). For each AI platform: documented review of data privacy terms, training-data opt-out status, retention, and Massachusetts security standard compliance. The AG Advisory makes this a Ch. 93H question, not just an ethics question.
2. (Owner: firm administrator) Attorney and staff training log (Mass. RPC 1.1, 5.1, 5.3). Capture date, attendees, and AI training content: hallucination risks, candor obligations under Rule 3.3, the firm’s AI use policy, and confidentiality obligations under Rule 1.6. Dastou ordered MCLE as a remedy; prior training records are a mitigant.

Months four to six (per-matter discipline)

These are recurring practices, not one-time projects: each new matter exercises them.

1. (Owner: matter lead attorney) Per-matter AI use notes (Mass. RPC 1.1, 3.3). On any matter where AI generated research, drafted pleadings, or produced filed content, a brief attorney note: which tool, what tasks, how output was verified.
2. (Owner: managing partner) Incident response procedure for AI errors (Mass. RPC 3.3, 1.4). Defined process if AI-generated content is filed in error. Include prompt disclosure to the tribunal under Rule 3.3 and client notification under Rule 1.4.
3. (Owner: billing partner) Billing review for AI-assisted work (Mass. RPC 1.5). The Dastou no-billing sanction targeted defective AI work. Bills should reflect actual attorney time, and any AI tool cost pass-through should be disclosed in the engagement letter.
