Who Issues Warrants in Mamaroneck
In New York an arrest warrant is signed by a judge. For Mamaroneck that means the Westchester County Supreme and County Courts, which hear divorces and major civil cases in the Supreme Court, felonies in the County Court; the city, town and village courts, which take misdemeanors, traffic cases and small claims, issue their own warrants on the cases before them.
A bench warrant follows a missed court date in any of those courts. Whichever kind it is, the warrant is part of the file of the case it was issued in, and the County Clerk keeps that file.

Whether a warrant is out from Mamaroneck shows in four places:
- The court file of the case, through the County Clerk at (914)995-3075, since a warrant is recorded in the case it was issued in.
- ECourts, the Unified Court System's free online case search (WebCivil, WebCrims and WebFamily), for a case whose register of actions shows a warrant.
- The District Attorney, which can say whether charges were filed; a warrant on a complaint follows the filing.
- The custody page of the sheriff's office at correction.westchestercountyny.gov, which shows people already arrested and booked, not open warrants.
Not one of the Westchester County pages SearchSystems verified (the sheriff's, the court's and the prosecutor's) is a list of open warrants, so a check means asking the court or the prosecutor about a case by name.
Clearing a Warrant from Mamaroneck

A missed date in a case before the city, town and village courts is handled by that court, not by the Westchester County Supreme and County Courts.
