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