Jurisdictional Context
Why Local Counsel Matters in Phoenix
Practicing law in Arizona. Legal matters in Arizona are governed by state-specific rules of civil and criminal procedure, statutes of limitations, and substantive law. Cases originating in Phoenix are typically filed in the local municipal court or the appropriate Arizona state district court, depending on subject matter and amount in controversy. An attorney licensed in Arizona brings working knowledge of local procedural deadlines, judicial practices in this venue, and the substantive law that applies to cases brought here. Out-of-state attorneys generally cannot represent clients in Arizona courts without local counsel or pro hac vice admission.
