California Enacts New AI Law Regulating Attorney Use of Generative AI in Legal Practice
California Governor Newsom signed Senate Bill 574 into law on September 30, 2026, making California the first state to statutorily regulate attorneys' use of generative AI. Effective January 1, 2027, the law adds Business and Professions Code section 6068.1, which prohibits attorneys from delegating the practice of law to generative AI. It mandates that attorneys take reasonable steps to verify AI output, correct fabricated content, and implement confidentiality safeguards. The law also amends Code of Civil Procedure section 128.7, requiring the attorney responsible for a pleading to personally verify every citation, regardless of whether AI supplied it. Additionally, attorneys must disclose the use of generative AI to the court for all submitted documents. This legislation comes in response to incidents where attorneys filed briefs containing fabricated citations and information generated by AI, as seen in cases like Mata v. Avianca, Inc., Noland v. Land of the Free, L.P., and LNU v. Blanche.
