Jurisdictional Context
Why Local Counsel Matters in Miami
Practicing law in Florida. Legal matters in Florida are governed by state-specific rules of civil and criminal procedure, statutes of limitations, and substantive law. Cases originating in Miami are typically filed in the local municipal court or the appropriate Florida state district court, depending on subject matter and amount in controversy. An attorney licensed in Florida brings working knowledge of local procedural deadlines, judicial practices in this venue, and the substantive law that applies to cases brought here. Out-of-state attorneys generally cannot represent clients in Florida courts without local counsel or pro hac vice admission.
