Why Local Counsel Matters in Chicago
Practicing law in Illinois. Legal matters in Illinois are governed by state-specific rules of civil and criminal procedure, statutes of limitations, and substantive law. Cases originating in Chicago are typically filed in the local municipal court or the appropriate Illinois state district court, depending on subject matter and amount in controversy. An attorney licensed in Illinois brings working knowledge of local procedural deadlines, judicial practices in this venue, and the substantive law that applies to cases brought here.
