Is Your AI Conversation Privileged?
08 May 2026
Recent US court decisions have, for the first time, tested whether conversations with AI tools can be protected by legal privilege. In United States v. Heppner, a court held that documents generated by a defendant using a public AI platform were not protected by attorney‑client privilege, largely because the AI was not used within a lawyer‑directed relationship and the platform’s terms allowed data retention and disclosure. By contrast, in Warner v. Gilbarco, another court found that AI‑assisted materials created by a self‑represented litigant were protected under the work‑product doctrine, which has a more forgiving standard for waiver.
