In December 2025 an Assistant U.S. Attorney in the Eastern District of North Carolina filed a response brief for the Department of Defense in a self-represented veteran's lawsuit over health-insurance coverage. The plaintiff identified fabricated quotations and misdescribed case holdings in it. The attorney first attributed the errors to an unfinalized draft filed by mistake. On 2 March 2026 Magistrate Judge Robert T. Numbers II ordered him to show cause why he should not be sanctioned. At the 10 March hearing the attorney, Rudy Renfer, said under oath that he had accidentally overwritten his draft, panicked and used artificial intelligence to draft the brief, and had not verified the cases it cited; he said he had resigned after 17 years in the office, and Courthouse News reported he was terminated the next day. On 28 April 2026 the court issued a public reprimand instead of a fine, writing that his reputation was in tatters and that his job loss already exceeded the usual fines.

On 23 February 2026 Paolo Molesini, then chairman of Fideuram (the private-banking subsidiary of Intesa Sanpaolo), received a WhatsApp message from an unknown number from someone claiming to be Intesa's chief executive Carlo Messina, announcing a confidential acquisition that had to be executed through Fideuram. The same day a caller presenting as a lawyer of A&O Shearman whom Molesini knew, whose voice ANSA, Il Fatto Quotidiano and Corriere della Sera, reporting from the Milan court papers, describe as created with artificial intelligence (today.it, which also cites the seizure decree, writes that the court papers do not yet answer whether the voice was imitated), had him sign a confidentiality agreement and sent eleven payment instructions; Fideuram's treasury head was separately contacted by someone posing as Fideuram's CEO. Between 23 and 25 February eleven transfers totalling about 95 million euros went to accounts in Portugal and at Bank of China; the bank's alarm systems and the Milan prosecutors recovered about 40-42 million from China and 13 million seized in Portugal, leaving at least 36 million (39.5 million per the court papers) missing after conversion into cryptocurrency. Molesini, who Corriere writes is not under investigation, resigned as chairman on 12 March 2026, which Fideuram announced as being for personal reasons; a 48-year-old Israeli citizen is under investigation as a member of the gang.

In a fee dispute between a Louisiana attorney and the City of Aberdeen, Mississippi, briefs filed for both sides in late 2025 cited six cases that do not exist. The attorneys admitted the citations came from unverified AI use: the plaintiff's out-of-state counsel, Kathleen M. Wilson, drafted her filing with an AI drafting program called 'First Drafts', and the City's out-of-state counsel, Kathryn Y. Williams, used an in-house AI legal research tool. Senior Judge Sharion Aycock stayed the case and cancelled the March 2026 trial, then on 8 June 2026 revoked both attorneys' pro hac vice admissions, barred them from the district for two years and fined them $2,500 and $3,500, and disqualified and fined the two local counsel who had signed the filings. Both litigants were left without counsel and given 60 days to find new representation.

On 25 August 2026 the Solicitors Disciplinary Tribunal struck Abhishek Kumar off the Register of Foreign Lawyers after finding proved that his 12 March 2026 Answer to the SRA's Rule 12 Statement contained misleading quotations and citations produced with generative AI — including a non-existent 'SRA v Chan [2020] EWHC 1502' and a miscited 'SRA v James, MacGregor & Naylor [2018] EWCA Civ 1420' that is actually an intellectual-property case — and that his 9 April 2026 email admitting AI use was itself AI-drafted with further errors. The tribunal said it would have struck him off on that allegation alone; the parallel ground was his January 2024 conviction under s.21 of the Immigration, Asylum and Nationality Act 2006. This is the SDT's first case on a lawyer's use of AI, per the SRA's counsel.

Santa Fe defense attorney Stephen Aarons used ChatGPT (OpenAI's o3) on a Rev.com transcript and the record to draft briefing in the murder appeal of Oscar Renee Sandoval; the brief contained fabricated witnesses and testimony (including police officers 'Michelle Amarillo' and 'Sanchez' and invented testimony attributed to real people) and misdescribed real precedents. After a 21 August 2026 show-cause hearing at which Aarons admitted he had not verified the output, the New Mexico Supreme Court's written order of 9 September 2026 held him in direct contempt, fined him $5,000 payable to the State Bar Client Protection Fund within 30 days, removed him from the case, barred him from appearing before the court pending a disciplinary-board referral, struck the filed briefs and reassigned the appeal to the public defender.
