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