Practicing law in California. Legal matters in California are governed by state-specific rules of civil and criminal procedure, statutes of limitations, and substantive law. Cases originating in Palo Alto are typically filed in the local municipal court or the appropriate California state district court, depending on subject matter and amount in controversy.
