AI Liability Insurance for Law Firms

What AI liability insurance is

AI liability insurance covers a risk that lacks a clean home in the existing policy stack: financial liability when a regulated professional uses artificial intelligence in client-facing work. For licensed attorneys, the risk lands first against the lawyers professional liability (LPL) policy. That is the malpractice-cover form most US firms carry. Whether the LPL policy actually pays an AI-driven claim is the load-bearing question. In 2026, the answer is bifurcated.

Two related cover concepts are emerging. The first is silent AI cover: an existing professional liability or errors and omissions form has not been amended for AI, so the carrier adjudicates an AI-related claim under pre-existing policy language. The second is affirmative AI cover: a separate product or endorsement that explicitly covers AI-related claims. Affirmative cover typically conditions on documented governance practices and an AI risk assessment.

Through 2024 and 2025, almost all US law firms operated under silent AI cover by default, and most still do. The change so far shows up in broker-reported underwriter questions, one reported manuscript exclusion on a non-standard lawyers program, and a small affirmative-coverage market, not in the printed LPL application forms: of those reviewed for this site, only AmTrust's asks about AI. Sections below describe what has been filed publicly, what remains unannounced, and how a firm can reduce exposure on either side at renewal.

Does my LPL policy cover AI mistakes?

The honest answer: "it depends on your policy and your carrier, and the market is starting to move." WTW's Insurance Marketplace Realities 2026, Errors and Omissions outlook (October 2025), reports that as lawyers' AI use increases, LPL underwriters are concerned with oversight, compliance with professional ethical standards, and "tight controls over AI selection and use to ensure accuracy," and are focused on training and supervision. Outside LPL, AI exclusions are already on filed forms in management liability and general liability, and a small affirmative-coverage market has opened.

For a firm at renewal, the assumption "I have LPL, so AI is covered" is no longer a reliable default. Suppose a claim alleges that a lawyer cited a hallucinated case to a tribunal. Or suppose confidential client information was disclosed through a self-learning tool. The carrier will analyze the claim against the actual policy form on the date of the alleged act. That form may be silent on AI, may have an exclusion endorsement attached, or may have an affirmative coverage grant. Three carriers writing the same LPL line can land in three different places.

For law firms, the evidence of underwriter attention to AI comes from broker reporting, not from the application forms. Sean Burke, a senior broker at Jencap, told IA Magazine in March 2026 that agents "can tell their law firm clients what to expect from underwriters by asking 'How are you utilizing AI?' on renewals," and added:

"For now, it remains largely a check-the-box inquiry as underwriters continue to monitor how AI adoption evolves."
Sean Burke, Jencap, in IA Magazine, March 2026.

Burke expects firms without documented protocols to fall out of preferred-risk tiers over the next 12 to 18 months. The printed forms have not caught up: the public LPL applications of The Bar Plan, TLIE, WILMIC, FLMIC, and ALPS, re-checked September 28, 2026, ask nothing about AI, and AmTrust's is the only one reviewed for this site that does. The accounting-firm market shows the same early stage. Stan Sterna, a risk control lead at Aon (which administers the AICPA Member Insurance Program), told Digital Insurance in April 2026 that professional liability underwriters are asking CPA firms "Do you use AI? Do you police it? Do you have protocols in place?", while noting that, unlike cyber underwriters, they do not yet work from a set list of AI questions: "It's not like that yet with AI, at least on the professional liability framework."

Which carriers have AI exclusion endorsements?

As of September 2026, the headline is narrower than trade-press coverage suggests. No filed AI exclusion on a lawyers professional liability form has been located in the admitted market, from the large writers (CNA, Travelers, Chubb, Hartford, Markel, ALPS) or from any state mutual. The AI exclusions located sit on adjacent lines: management liability (D&O, EPL, Fiduciary) and general liability. The one located LPL example is a reported manuscript endorsement on an unnamed carrier's non-standard lawyers program, with its admitted or surplus-lines status undisclosed and no filed form located, which is why the accurate statement is "no filed exclusion located in the admitted market," not "no AI exclusion on any LPL form."

The exclusions most often cited at renewal, and what each one actually is:

• W. R. Berkley, Form PC 51380 00 (06-24), Artificial Intelligence Exclusion (Absolute), amending Berkley's management liability base policy family. Hosted publicly via Hunton's regulatory tracking. Does not on its face attach to LPL forms.
• Hamilton (attribution unresolved). Law firm client alerts attribute a generative AI exclusion, defining generative AI to include ChatGPT, Bard, Midjourney, and DALL-E, to Hamilton Insurance Group; other commentary names Hamilton Select. No form number, filing, or carrier-hosted document has been located for either entity, and the exclusion language itself traces to the Vanguard Specialty report below.
• Verisk / ISO, CG 40 47, CG 40 48, CG 35 08: advisory general-liability exclusion endorsements with a January 2026 edition date, reported in trade press. Insurers adopt ISO forms state by state, so their presence on any given policy is not established by the forms themselves. Not LPL.
• Unnamed non-standard LPL program. On September 30, 2024, program manager Vanguard Specialty reported that a competitor to its Non-Standard Lawyers Professional Liability Program "is now attaching a manuscript endorsement" excluding any claim based upon any actual or alleged use of generative AI by the law firm. L Squared Insurance Agency republished the same report on October 7, 2024 under the byline of Stephen Van Wert of Vanguard Specialty, so the two postings describe one program, not two. The carrier is not named. Treat it as a market signal, not a single carrier's policy.

Existing LPL exclusions can already deny coverage on AI facts in four ways: the professional services definition, intentional acts, breach of confidentiality, and unauthorized practice. ALPS' August 2025 framework sets out the analysis. For the form-by-form breakdown, plus FY2025 10-K language from Travelers, Chubb, Markel, CNA, Hanover, and Berkley, see the carrier renewal documentation page. The carrier tracker has the per-carrier published-position breakdown.

Which carriers offer affirmative AI coverage?

Affirmative AI coverage is a separate product or endorsement that explicitly covers AI-related claims. It usually sells alongside (not in place of) the firm's existing LPL policy; one LPL product now builds it in. Carriers offering affirmative cover in 2026:

• Armilla AI with Lloyd's syndicate Chaucer (1084) and Axis Capital. Affirmative AI liability insurance, launched April 2025 and since raised to limits of up to USD 25M, expanded February 10, 2026 into "Vanguard AI" bundling cyber, technology E&O, and AI. Armilla's product pages describe no law-firm-specific form.
• Counterpart, US managing general agent. Launched Lawyers Professional Liability insurance on September 1, 2026, for firms of up to 100 lawyers, with its Professional Liability Affirmative AI Coverage included in the LPL policy. Earlier: affirmative AI coverage on miscellaneous professional liability (November 26, 2025), extended to every professional liability policy it writes (July 2026).
• Coalition. AI Coverage product within its cyber program; most relevant for cyber-adjacent AI exposure.
• Munich Re aiSure. Performance-warranty product for AI providers and corporate users, including aiSure-General Liability for bias and discrimination claims.
• Hiscox. Affirmative AI cover within its technology professional indemnity book.
• Beazley. Public posture is "no AI exclusion planned" (Bob Wice, February 2025), meaning silent AI cover by explicit choice, not by default.

Most of these products operate parallel to, not inside, traditional LPL. When a firm buys affirmative AI cover from Armilla or Munich Re, it sits on top of the existing LPL policy, not as a substitute. Counterpart's LPL product is the exception: as marketed, the AI grant is part of the malpractice product itself (the policy form was not reviewed). Underwriting requires a documented AI risk assessment as a precondition. Documentation that satisfies an existing LPL underwriter at renewal generally satisfies the affirmative-cover carrier too, which is the operational case for documenting once.

The per-carrier breakdown, including Lloyd's capacity, named broker channels, and the LMA International Professional Indemnity Committee report (September 2025), is on the carrier renewal documentation page.

What to ask your underwriter at renewal

Seven questions a firm can put to its broker or underwriter at renewal. None are unusual. If the carrier cannot answer them, that is the signal that it has not yet formed a posture.

1. Is silent AI cover still in effect on this policy form, or has it been amended for the renewal? If "amended," ask for the endorsement language in writing before binding.
2. Has the carrier filed any AI-specific exclusion endorsement on this line, in this state? The answer may be "not on this line yet"; that answer is informative because it tells you the form-side trajectory.
3. If an AI exclusion is added at any future renewal, what is the scope? The Berkley form is "absolute": any use, any deployment, any development. Some carriers will offer narrower carve-outs (specific tools, specific use cases). The scope question matters because absolute exclusion is materially different from a tool-list exclusion.
4. Does the carrier require an AI risk assessment, governance documentation, or training records as a precondition for renewal? If yes, ask for the specific documents the carrier wants to see, not just the categories. The list is the renewal binder.
5. Are there premium adjustments tied to AI use? No AI-specific rate or credit was located among the carriers reviewed, but Jencap expects firms without documented protocols to fall out of preferred-risk tiers, so ask how AI documentation affects tier placement.
6. If a claim involving AI arises, what notice triggers and timing requirements apply? AI-related claims may not fit cleanly into the policy's existing claim definition. Confirm the notice mechanics before a claim arises, not after.
7. Does the carrier offer affirmative AI cover as a separate product, and at what price point? Even if the answer is no, the conversation surfaces whether the carrier expects to.

A small number of carriers, particularly the state-affiliated mutuals, are ahead of the broader market on AI-specific risk-management content. Camille Stell at Lawyers Mutual of North Carolina (the LMLIC mutual that writes LPL for the NC bar) is one example. She has authored multiple practice-side AI articles since 2024 and published an AI Use Policy template in December 2025. If your carrier offers a published AI policy template, treat it as the starting point for the renewal conversation. The carrier has, in effect, told the firm what documentation it expects.

How to document AI use for renewal

Documentation a carrier wants at renewal in 2026 is not different in kind from what a regulator or a sanctioning court would want. ABA Formal Opinion 512 is the national baseline ethics opinion on generative AI for lawyers. It maps directly to nine renewal-readiness artifacts. A firm that can produce all nine has what the carrier is most likely to request, plus a defensible record if a claim arises.

• Written firm AI policy (Rules 5.1, 5.3): a current policy, dated within the last 12 months, naming approved tools, prohibited uses, and supervisory responsibility.
• Vendor due-diligence file (Rules 1.1, 1.6): for each approved tool, terms of use, privacy policy, data retention, and training-on-input behavior reviewed and recorded.
• Tool-specific informed-consent language (Rule 1.6): for any self-learning tool into which client information is input, client-facing consent language that meets Opinion 512's "not boiler-plate" standard.
• Training and CLE records (Rules 1.1, 5.1, 5.3): every attorney and staff member using an approved tool has completed tool-specific training, logged by date.
• Pre-filing verification log (Rule 3.3): any filing that used AI research assistance is logged with the citation-verification step documented by the reviewing attorney.
• Usage log (Rules 5.1, 5.3): cross-matter register of who used which AI tool on which matter.
• Incident response procedure (Rule 1.6): a written procedure for AI-related confidentiality incidents, including client notification and bar reporting.
• Quarterly attestation (Rule 5.1): managing-partner sign-off, every quarter, that the program is current.
• Renewal-ready audit report: one-page status memo summarizing the program, suitable as the cover document for the carrier submission.

Each artifact is available as a free template on this site. A firm that adopts all nine has the renewal binder. The Opinion 512 compliance guide maps each rule to the artifact that documents it. State-specific overlays appear in the state tracker; where state guidance is stricter than Opinion 512, the state rule controls.

What is changing in 2026 and 2027

Three forward indicators are worth tracking from a firm's perspective.

• Claim volume is climbing. Generative AI-related US lawsuits rose 978% from 2021 to 2025. More than 700 cumulative cases were reported as of early 2026. Gartner has forecast more than 2,000 "death by AI" legal claims by year-end 2026 across all lines.
• The first publicly reported LPL claim denial citing an AI exclusion has not yet landed. When it does, expect underwriting questions to harden quickly. Document AI governance now, before that pressure arrives.
• State regulatory action is uneven. The NAIC AI Model Bulletin (December 2023) and the NY DFS Circular Letter No. 7 govern insurers' own use of AI in underwriting and pricing, not exclusion language in professional lines. As of May 2026, no state insurance regulator has issued a circular letter specifically addressing AI exclusions in professional liability.

Three things follow for a firm planning 2026 and 2027 renewals. Assume silent AI cover will not last indefinitely. Expect the affirmative-coverage market to expand and require documented governance as a precondition. Watch for the first publicly reported LPL claim denial as the trigger event for accelerated form-side change. Lloyd's market timing (Y-prefix bulletin status, LMA International PI Committee September 2025 report) is on the carrier renewal documentation page.
