Jurisdictional Context
Why Local Counsel Matters in Philadelphia
Practicing law in Pennsylvania. Legal matters in Pennsylvania are governed by state-specific rules of civil and criminal procedure, statutes of limitations, and substantive law. Cases originating in Philadelphia are typically filed in the local municipal court or the appropriate Pennsylvania state district court, depending on subject matter and amount in controversy.
