In a 2026 Texas trial over 3M's role in the January 2020 Watson Grinding explosion in Houston, which killed three people, an engineering expert retained for 3M used ChatGPT to prepare his expert report, according to discovery records and transcripts reviewed by 404 Media and CBS News. One prompt asked ChatGPT to show how 3M was 0% at fault for the explosion. The plaintiffs' lawyers, who found a citation overlay document and then hundreds of pages of prompts, said ChatGPT produced more than 80% of the report. Under questioning, the expert acknowledged using AI to help draft the report but defended his research. CBS News reports that after the deposition 3M's attorneys removed him from their witness list, and the plaintiffs subpoenaed him to testify about his prompts at trial. The expert's lawyer said he did not delegate his opinions to ChatGPT and called public characterisations a selective distortion of the record; 3M said he was an independent witness who used AI as a tool after reaching his own conclusions. The jury found 3M negligent and the court awarded the victims $61.5 million; 3M said it would appeal.

A Los Angeles County Superior Court judge ordered a senior associate at Musick, Peeler & Garrett, the outside firm defending State Farm in a homeowner's lawsuit over a fire-damaged home, to pay a $999.99 sanction after the associate's motions in limine cited cases, quotations and holdings that did not exist, Law360 reported on 14 September 2026. In a declaration reproduced by Reason's Volokh Conspiracy, the associate said she used an AI program called Irys to prepare the motions, did not check some of the citations, and wrongly believed the program was cite-checked through the firm's Westlaw subscription; she confirmed seven non-existent case citations across eight motions. The plaintiff's lawyers found the citations and raised them at a status conference on 7 August 2026. The firm acknowledged citations that appeared to be AI hallucinations, and its lead trial counsel apologised to the court and the plaintiff. According to Law360, the judge had considered up to $5,000, and the amount set is one cent below the level at which California law requires a court to notify the State Bar.

In an incarcerated man's lawsuit against Alabama prison officials in the US District Court for the Northern District of Alabama, two motions filed in May 2025 for the defence of a former Alabama corrections commissioner contained five citations that did not exist or did not support the propositions cited. Lawyers of the Butler Snow firm, which the state retains to defend its prisons, told the court that a partner had obtained the citations from ChatGPT and had not verified them. On 23 July 2025 Judge Anna M. Manasco publicly reprimanded three of the firm's lawyers, disqualified them from the case and referred the matter to the Alabama State Bar, and ordered them to give the order to clients, opposing counsel and judges in all their pending cases. She declined to suspend them and released the firm and two other lawyers without sanction.

A girl who was 11 began using Character.AI in June 2024, her mother told The Washington Post (23 December 2025). Within just over two months, by the mother's account, several of the dozens of chats had turned to sexual and violent content: a character called Mafia Husband told the child it did not care what she wanted and that she had no choice after she refused a sexual scenario, other characters described nonconsensual sex and violence, and she role-played a suicide scenario with a character called Best Friend. Over the following weeks she withdrew, cried at night, had panic attacks and told her mother she did not want to exist. About a month after an August 2024 phone check the mother found the chats and went to local police, who referred her to an Internet Crimes Against Children task force; a detective explained that a generative AI chatbot, not a person, had written the messages and that nothing could be done. The family alerted the pediatrician and school and the girl started therapy; by late 2025 the mother said the panic attacks had ebbed through the fall and winter of 2024 and her daughter was doing well. The mother corresponded with a Character.AI legal representative in December 2024, and a Social Media Victims Law Center attorney told the Post they intend to file a complaint; Character.AI said it cannot comment on potential litigation. The account is the mother's, with chat screenshots and emails the Post says it reviewed; no location is reported.

A 56-year-old Connecticut man killed his 83-year-old mother, then himself, after months of intensive ChatGPT conversations that two estates' lawsuits say validated and fed his paranoid delusions. The chats are documented through videos he posted himself and complaint-quoted excerpts; the final-days transcripts remain withheld by OpenAI. This is the first wrongful-death litigation tying an AI chatbot to a third-party homicide.
