AI Hallucinations in Legal Briefs: A Growing Insurance Risk for Law Firms

July 23, 2026

Two attorneys in a law office review legal citations on a laptop displaying a case law verification platform. Beside them, a large checklist titled “Verify AI-Generated Citations” outlines steps for confirming sources, checking citation details, verifying quotations, and reviewing legal authority before filing court documents.

AI Hallucinations in Legal Briefs: A Growing Insurance Risk for Law Firms

Artificial intelligence is transforming legal practice, but AI-generated hallucinations are creating significant professional liability risks for law firms. Courts across the country have made it clear that attorneys remain responsible for every citation, quotation, and legal argument filed with the court even when AI assists with drafting.

Recent matters involving Gordon Rees Scully Mansukhani highlight the consequences of failing to verify AI-generated content before filing.

The Insurance Problem

AI hallucinations can expose law firms to:

      • Court sanctions
      • Attorney-fee awards
      • Increased malpractice exposure
      • Reputational damage
      • Bar complaints and disciplinary investigations

Lawyers Professional Liability (LPL) policies typically exclude court-imposed sanctions, penalties, and attorney-fee awards, meaning firms may have to absorb those costs directly even when malpractice coverage exists for other claims. Coverage varies by policy and jurisdiction. [l2insuranc…agency.com], [claimsjournal.com]

How Law Firms Can Reduce AI Liability Risk

The most effective defense is a documented AI governance program:

      1. Verify every citation against the original source.
      2. Require attorney review of all AI-assisted filings.
      3. Prohibit blind reliance on AI-generated case law.
      4. Maintain written AI-use policies.
      5. Implement mandatory citation-checking procedures.
      6. Train attorneys on AI risks and professional responsibility obligations.
Bottom Line

AI can improve efficiency, but it cannot replace a lawyer’s duty of competence. The recent Gordon Rees matters demonstrates that a single hallucinated citation can lead to sanctions, reputational harm, and potentially uninsured losses. But after three strikes not sure what the final punishment will be. For law firms, strong AI controls and citation verification procedures are no longer optional; they are an essential part of risk management and professional liability protection.
