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