California’s New Legal Rules for 2026: AI, Photo Proof of Service, and Simpler Statements of Decision

New statutes and court rules taking effect in 2026 and 2027 will change how California lawyers serve papers, preserve appellate issues, and disclose their use of artificial intelligence. Appellate attorneys Tim Kowal and Jeff Lewis focus on what actually matters in practice—what to fix now, and where the new traps are likely to appear.

The big changes:

• AI in the Courts: Rule of Court 10.430 requires courts to either ban AI use by judicial officers and research attorneys or adopt a formal AI policy with verification and disclosure requirements. Expect cautious policies, broad disclosures, and little tolerance for “the AI did it” excuses.
• One Deadline for Statements of Decision: AB 515 eliminates the short-trial/long-trial distinction. If you want a statement of decision, you must request it before submitting…and you should do it in writing.

Other changes worth noting:

• Photo Proof of Service: Starting January 2027, AB 747 requires process servers to document service attempts with photographs showing GPS coordinates and timestamps.
• Court Reporter Disclosure: AB 711 requires meet-and-confer declarations to disclose whether court reporter attendance was discussed and the outcome.
• Electronic Service Authorized: SB 85 allows courts to approve service by email or electronic means when traditional service fails.
• Expanded Mediation Authority: Courts may order mediation in cases up to $75,000 if at least one party requests it and no discovery disputes are pending.
• AI Disclosure in Bankruptcy Court: The Southern District of California Bankruptcy Court now requires disclosure of AI tools used and certification of independent accuracy review.
