California has issued practical guidance on generative AI use rather than a formal ethics opinion. The guidance is non-binding but represents the State Bar’s current position on attorney obligations under the California Rules of Professional Conduct.

Proposed formal rule amendments are under active development as of April 2026, with a Board of Trustees vote anticipated in May 2026. Firms should monitor the State Bar website for updates.
