Who Issues Warrants in Rensselaer County
In New York an arrest warrant is signed by a judge. For Rensselaer County that means the Rensselaer 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.
Statewide, eCourts is the Unified Court System's free online case search (WebCivil, WebCrims and WebFamily).

How to Check for a Warrant in Rensselaer County
The places to check for a warrant from Rensselaer County:
- 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.
Not one of the Rensselaer County pages SearchSystems verified (the sheriff'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 Rensselaer County
A warrant is recalled by the court that issued it, so clearing one from Rensselaer County starts with the County Clerk: the case goes back on the calendar and the judge recalls the warrant when the person appears.
A missed date in a case before the city, town and village courts is handled by that court, not by the Rensselaer County Supreme and County Courts.
A lawyer can often arrange the appearance in advance. The District Attorney's page SearchSystems verified is at history.nycourts.gov.
