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.
