A recent federal court ruling has prompted significant changes in how law firms address the use of AI chatbots in legal contexts. In the case of United States v. Heppner, Judge Jed Rakoff ruled that private conversations with Anthropic’s Claude could be used as evidence against a fraud defendant, emphasizing the lack of legal privilege since Claude is not a licensed attorney, and the conversations were not directed by legal counsel. This unprecedented ruling has led over a dozen major U.S. law firms to issue advisories warning clients that discussions with AI tools like Claude or ChatGPT may lack legal protection, prompting firms to incorporate specific warnings into engagement contracts. Meanwhile, contradictory rulings in civil courts suggest that pro se litigants may still find some protections for their AI-generated work.
Jed Rakoff: Jed S. Rakoff is a senior United States District Judge for the Southern District of New York since 1996, known for authoring influential opinions and sitting by designation on appellate courts. In United States v. Heppner, he issued the first written federal opinion holding that private conversations with AI like Claude lack attorney-client privilege absent an attorney relationship or direction.
Kobre & Kim: Kobre & Kim is a global, conflict-free law firm focused exclusively on disputes and investigations involving international fraud and misconduct, with offices across the Americas. Lawyer Alexandria Gutiérrez Swette represents institutional clients in high-stakes commercial disputes. The firm issued client advisories warning about lack of legal protection for AI chatbot conversations on legal matters.
Justin Ellis: Justin Ellis is a partner at MoloLamken LLP, litigating high-stakes business disputes through trials and appeals in federal and state courts. He commented to Reuters that additional court rulings are needed to clarify when AI-generated chats can be used as evidence in cases.
Sher Tremonte: Sher Tremonte is a New York City-based litigation boutique specializing in complex commercial disputes, internal investigations, and high-stakes white-collar matters. The firm regularly represents white-collar criminal defendants. It added explicit language to a March engagement agreement warning clients that disclosing privileged communications to third-party AI platforms may waive attorney-client privilege, one of the first to formalize the Heppner ruling in contracts.
Bradley Heppner: Bradley Heppner is the former CEO and board chairman of GWG Holdings, indicted on federal charges including securities fraud and wire fraud for allegedly misappropriating funds from the bankrupt company. In response to a subpoena, he independently used Anthropic’s Claude to generate defense documents seized by the FBI. Judge Rakoff ruled these AI-generated materials lacked attorney-client privilege.
O’Melveny & Myers: O’Melveny & Myers is an international law firm headquartered in Los Angeles, renowned for its award-winning litigation practice that reduces client exposure through early resolutions or inventive strategies. The firm advised clients to use only closed, enterprise-grade AI systems for legal work, acknowledging the untested status of such tools in court.
Debevoise & Plimpton: Debevoise & Plimpton is a premier international law firm with market-leading practices in private equity, M&A, and white-collar matters, maintaining strong New York roots and a global perspective. It provided tactical advice for clients to explicitly note attorney direction within AI prompts to potentially invoke the Kovel doctrine for privilege protection.
Alexandria Gutiérrez Swette: Alexandria Gutiérrez Swette is a seasoned trial lawyer at Kobre & Kim, handling high-stakes commercial disputes and cross-border investigations for institutional clients and executives. She told Reuters that the firm is advising clients to proceed with caution when using AI chatbots for legal matters due to lack of privilege protection.
