Jurisdictional Context
Why Local Counsel Matters in Houston
Practicing law in Texas. Legal matters in Texas are governed by state-specific rules of civil and criminal procedure, statutes of limitations, and substantive law. Cases originating in Houston are typically filed in the local municipal court or the appropriate Texas state district court, depending on subject matter and amount in controversy. An attorney licensed in Texas 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 Texas courts without local counsel or pro hac vice admission.
