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