A recent Manhattan federal court ruling has prompted major law firms to warn clients that anything shared with consumer AI chatbots can be subject to legal discovery, leading lawyers to recommend using only enterprise-level AI tools with contractual confidentiality guarantees when handling sensitive information.

Why it matters

This ruling highlights the legal risks of using consumer-facing AI chatbots for anything related to active or potential litigation, as courts may not recognize attorney-client privilege or work product protections for content shared with these public platforms. Law firms are now scrambling to revise client contracts and internal policies to mitigate these new legal liabilities.

The details

In the case of United States v. Heppner, U.S. District Judge Jed S. Rakoff ordered a defendant to hand over 31 documents created with Anthropic's Claude AI chatbot, ruling that the AI-generated materials were not protected by privilege. The court found the exchanges failed to meet basic privilege requirements, as they were not communications with a lawyer, the user could not reasonably expect confidentiality, and the work was not performed at the direction of counsel.

  • On February 17, 2026, Judge Rakoff issued a written opinion on the case.
  • In the wake of the ruling, law firms began revising engagement letters and circulating AI warnings to clients.
