Overview
- Nippon Life Insurance Company of America filed a federal complaint in the Northern District of Illinois seeking an injunction and about $10.3 million in damages.
- The insurer alleges ChatGPT posed as a lawyer for an Illinois woman, leading her to dismiss her attorney and pursue new actions after a settled disability dispute.
- According to the complaint, the chatbot drafted dozens of pro se filings that included fabricated case citations described as AI hallucinations.
- A court ruled on Feb. 13, 2025 that the woman could not reopen the case, yet she filed additional motions and a new suit that Nippon attributes to ChatGPT’s guidance.
- OpenAI says the complaint lacks merit, and by October 2025 the company had restricted tailored legal advice and court document drafting on ChatGPT.
