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