Litigation in California
Practicing litigation in California means navigating a distinct legal environment.
California's judiciary is the largest state court system in the United States, organized into the Supreme Court, six Courts of Appeal with appellate districts spanning the state, and 58 Superior Courts. one per county. The system handles more than six million filings annually.

Litigation Practice in CA
California's Superior Courts use a complex notice pleading system supplemented by extensive discovery rules under the California Code of Civil Procedure, and the Judicial Council maintains mandatory and optional forms that shape motion practice statewide.
Does California require AI disclosure? Case-by-case.
California does not have a single statewide rule that requires lawyers to disclose AI use to a court or a client. The State Bar's official guidance directs lawyers to consider disclosing AI use to the client when it materially affects decision-making, and to verify every AI output before it is filed. Several individual judges and federal courts in California do require disclosure or certification in their own filings, so counsel must check the local rules and the assigned judge's standing order in each matter.
