California Signs First-in-Nation Law Setting Statutory Rules for Lawyer AI Use
Governor Newsom has signed SB 574, establishing California-specific statutory boundaries on how attorneys may use artificial intelligence, putting in-state and AI-touched practice on notice.
California Governor Gavin Newsom has signed Senate Bill 574, described by Seyfarth Shaw as a first-in-the-nation measure that would place clear statutory limits on attorneys' use of artificial intelligence. The practical significance is that California has moved AI-use obligations for lawyers from the professional-conduct and rules-of-court layer into codified statute, giving opposing counsel a legislative hook that did not previously exist.
Why sophisticated counsel should care: the firm headlines this as opening a "new era" of AI regulation, and firms with California-licensed lawyers, California-facing matters, or practices built on generative tooling all face the same exposure question. A statutory framing also tends to carry more force — cure provisions, duty-of-care angles, and potential malpractice or disciplinary theories — than conduct rules alone. Clients in litigation-heavy or regulated industries should be able to explain how AI was used in their matter and who reviewed the output.
Action to watch: the operative provisions, effective date, and any implementing guidance, which determine whether the obligations bite immediately or later. Evidence here is one firm alert, so section numbers, specific duties, and sanctions are unconfirmed and should be checked against the enacted text before client advice.
