Who Issues Warrants in Union County
In New Jersey an arrest warrant is signed by a judge. For Union County that means the Superior Court of New Jersey, Union County, which hears every civil, criminal, family and probate case. A city with a municipal court of its own issues warrants on the tickets and ordinance cases it tries.
When a defendant misses a court date the judge issues a bench warrant, and either kind of warrant lives in the court file of the case, kept by the Superior Court Clerk and the County Clerk.
The court records page SearchSystems verified for the county is at njcourts.gov/public/find-a-case (page title: Find a Case), which answered when SearchSystems opened it on September 23, 2026.

How to Check for a Warrant in Union County
Whether a warrant is out from Union County shows in three places:
- The court file of the case, through the Superior Court Clerk and the County Clerk, since a warrant is recorded in the case it was issued in.
- New Jersey Courts Public Access, the Judiciary's free online case search for civil and criminal cases, for a case whose register of actions shows a warrant.
- The custody page of the Union County Sheriff's Office at unioncountynj.org, which shows people already arrested and booked, not open warrants.
The one Union County page SearchSystems verified, the court's, is not a list of open warrants.
The statewide criminal history kept by the New Jersey State Police is not open to the public in New Jersey, so it is not a route to a warrant check on someone else.
Clearing a Warrant from Union County
A warrant is recalled by the court that issued it, so clearing one from Union County starts with the Superior Court Clerk and the County Clerk: the case goes back on the calendar and the judge recalls the warrant when the person appears.
