AI in Law Firms: Malpractice Risks

Artificial intelligence has moved into the mainstream of legal practice. Attorneys use large language models to draft contracts, summarize depositions, research case law, and prepare discovery responses. Used well, these tools save hours of billable time. Used carelessly, they create exactly the kinds of errors that lawyers professional liability insurance exists to cover.

If your firm uses AI, or is considering it, here is what you need to know about how it changes your malpractice exposure.

AI Makes Classic Malpractice Mistakes Faster

The core duty has not changed. You owe every client competent representation, and you remain fully responsible for the work product that leaves your office, no matter which tool helped produce it. AI does not shift that responsibility, it accelerates the risk:

• **Hallucinated citations.** The most famous examples of AI-generated legal errors involve fabricated case law. Courts have sanctioned attorneys for filing briefs citing decisions that do not exist. Even a single fake citation can trigger a malpractice claim, a bar complaint, or both.
• **Confident but wrong analysis.** AI tools can misstate the law, apply the wrong jurisdiction's rules, or overlook recent changes. The output reads convincingly, which makes errors harder to catch.
• **Confidentiality breaches.** Pasting client information into a public AI tool may violate your duty of confidentiality, and depending on the tool's terms, that information may be retained or used for training. Many carriers now treat this as a data-privacy exposure as well as an ethical one.
• **Missed deadlines from over-reliance.** Attorneys who lean on AI for calendaring, summarization, or workflow management can miss statutes of limitations when the tool is wrong or the prompt was incomplete.

What Underwriters Are Asking Now

Carriers have responded. AI-related questions are appearing on lawyers professional liability applications, and how you answer them affects both eligibility and premium:

• **Do you use generative AI, and for which tasks?** Drafting, research, summarization, and client communication are treated differently.
• **Do you have a written AI use policy?** Firms with clear policies on approved tools, prohibited uses, and human review requirements present a better risk.
• **Human review.** Carriers want to see that an attorney reviews and verifies all AI-assisted work product before it goes to a client or a court.
• **Data security.** Whether client data is shared with public AI models, and what contractual protections exist.

Some carriers have begun offering better terms to firms with documented AI governance, while a few surcharge or restrict coverage for certain AI uses. Disclosure is essential. Concealing AI use can jeopardize a claim when it surfaces during underwriting of the loss.

Does Your Policy Cover AI-Related Claims?

This is the question to ask your broker. Coverage for AI-related claims depends on policy language:

• **Professional services definition.** Most policies cover claims arising from legal services. If AI is part of how you deliver those services, claims should generally fall within coverage, but exclusions vary.
• **Cyber and data-privacy exclusions.** A confidentiality breach involving an AI tool may be treated as a cyber event, which many professional liability policies exclude. A separate cyber policy may be needed.
• **Intellectual property claims.** AI outputs trained on third-party work can raise copyright questions. Some policies exclude IP claims, others cover them.

Do not assume your current policy handles AI risks the same way the next one will. Policy forms change at renewal, and carriers are actively revising their approach.

A Practical Risk Management Checklist

Firms using AI should be able to answer yes to all of the following:

1. We have a written policy defining which AI tools are approved and what tasks they may be used for. 2. No confidential client information is entered into public AI tools. 3. An attorney independently verifies all citations, legal conclusions, and calculations in AI-assisted work. 4. AI use is disclosed in engagement letters where appropriate. 5. We have reviewed, or asked our broker to review, how our policy treats AI-related claims.
