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