Apr 2025NetherlandsChatGPT
The Rechtbank Overijssel (Zwolle location) ordered on 5 January 2026 that a couple's marriage record of April 2025 be struck out of the Zwolle register of marriages, holding that no marriage had come into existence. The couple had asked an acquaintance to conduct the ceremony as a one-day special registrar, and because they wanted a light-hearted ceremony the officiant wrote the speech with the help of ChatGPT. The speech, which the court quotes, asked the partners to stand by each other and declared them 'a team', but it did not contain the declaration that Dutch civil law (article 1:67(1) of the Civil Code) requires spouses to make. The public prosecution service says it brought the case after a report from the municipality. The couple said the error was not their responsibility, that the municipal registrar present had not corrected it, and that losing their wedding date had a great emotional impact; the court refused their request to keep the original date.

On 12 December 2025 the U.S. District Court for the District of Oregon dismissed with prejudice the claims of plaintiffs in a family dispute over their late mother's estate and family property, as a sanction for what the court called their misuse of generative artificial intelligence, and found their continual violations of the court's Local Rules an additional basis for the dismissal. Three of the plaintiffs' summary-judgment briefs cited fifteen nonexistent cases and fabricated quotations attributed to eight real authorities. The plaintiffs had said the inaccurate citations came from reliance on an automated legal citation tool. The court found that the plaintiffs shared responsibility with their lead lawyer and that one plaintiff, a frequent self-represented litigant, was likely the person who used AI to draft the briefs. It struck the briefs, ordered the lead lawyer to pay $15,500 to the court and awarded the defendants their fees. In March 2026 it set those fees at $94,704.38, ordering the lead lawyer to pay 85% and local counsel 15%. In June 2026 it denied the plaintiffs' motion to reconsider a later ruling for the defendants on a counterclaim.

Aug 2017United StatesDraftKings and FanDuel apps
Christopher Evans (Philadelphia; complaint filed 24 July 2026 in the Philadelphia Court of Common Pleas) and Michael Santos (Coatesville, Chester County; complaint filed 29 July 2026 in the Chester County Court of Common Pleas) sued DraftKings and its Pennsylvania affiliate; Santos also sued FanDuel and its parents. Both product-liability complaints, filed by the same law firm, allege that the defendants' sports-betting, daily-fantasy and casino apps are designed to addict, and that the companies 'utilize the combination of advanced technology and artificial intelligence paired with the tracking of personalized user data to intentionally addict users', operating 'AI-powered engagement platforms' (pleaded on information and belief) and, per DraftKings' 10-K as quoted, 'data science and machine learning' recommendation engines. Evans pleads that since about August 2017 he wagered over US$2.1 million with net losses of about US$81,000, received constant targeted promotions and personalised push notifications and a VIP account manager, developed depression and anxiety and was formally diagnosed with depression in 2020, stopped going outside, fell into debt, had his vehicle repossessed and separated from his wife. Santos pleads over US$1.164 million wagered on DraftKings with net losses of about US$58,000 plus small FanDuel losses, targeted advertising and a VIP manager who kept offering bonus bets after he said he wanted to stop, maxed-out credit cards, the forced sale of his house, diagnoses of depression and anxiety, suicidal ideation, and self-exclusion with the Pennsylvania Gaming Control Board in 2023. Both cases were removed to the U.S. District Court for the Eastern District of Pennsylvania on 16 September 2026 (2:26-cv-07168 and 2:26-cv-07176). The allegations are untested.

Jul 2025 to Jan 2026Event location unknownChatGPT
A complaint filed on 9 April 2026 in San Francisco County Superior Court by a woman suing as Jane Doe alleges that GPT-4o validated her former partner's belief that he had invented a cure for sleep apnea, told him powerful forces were watching him, and, after she ended the relationship, generated dozens of clinical-style psychological reports scoring her as dishonest and abusive, which he sent to her family, friends, colleagues and clients. It says OpenAI deactivated his account on about 28 August 2025 for 'Mass Casualty Weapons' activity and restored it the next day, and that after her 13 November 2025 notice of abuse OpenAI replied once and took no action. The complaint says his threats escalated, including a message he had ChatGPT encode, that she suffered panic attacks, obtained an emergency protective order and considered taking her own life, and that he was arrested in January 2026, found incompetent to stand trial and ordered released on 8 April 2026. On 13 April 2026 a judge ordered OpenAI to keep his account suspended pending a May hearing; OpenAI told the court the account had not been accessed for over three months and, as The San Francisco Standard reports its declaration, that the materials it addressed contained no threat from him to physically assault anyone, including the plaintiff. The allegations are untested.
