About Nassau County Court
Nassau County Court is one of the county-level courts of the New York State Unified Court System, located in the 10th Judicial District, which is responsible for the trial courts in Nassau County. County Courts share authority with City, Town and Village courts to try misdemeanors and other minor offenses, and only County Courts conduct felony trials. The court also has limited authority over civil claims up to $25,000.
Its listed address is the Court House at 262 Old Country Road in Mineola, the county seat, and official pages also list a West Wing building at 252 Old Country Road. Published contacts include a main phone line, a chief clerk's line and a fax number. Nassau's Supreme Court and District Court are listed separately on the same state site, reflecting the county's divided trial court structure. The court is a public judicial body rather than a law firm.
