Why Local Counsel Matters in San Antonio
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 San Antonio are typically filed in the local municipal court or the appropriate Texas state district court, depending on subject matter and amount in controversy.
