Who Issues Warrants in Union County
In Pennsylvania an arrest warrant is signed by a judge. For Union County that means the Union County Court of Common Pleas, which hears felonies, civil cases, divorces, estates and juvenile matters; the Magisterial District Courts issue their own warrants on the cases before them.
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 Prothonotary for civil cases and divorces and the Clerk of Courts for criminal cases.
The court records page SearchSystems verified for the county is at ujsportal.pacourts.us/casesearch (page title: Case Search), which answered when SearchSystems opened it on September 30, 2026.

A person arrested on a warrant and kept in custody goes to the county jail, whichever agency made the arrest. The jail, run by the Union County Sheriff's Office, held about 46 people on an average day in 2023 by the Vera Institute of Justice's count and has a jail page SearchSystems verified at unioncountypa.org/departments/sheriff/sheriff-s-office/page.aspx. The Union County inmate search guide covers the jail in full.
A person arrested in Union County on a warrant from another county is held at the same jail until that county takes custody.
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 Prothonotary for civil cases and divorces and the Clerk of Courts for criminal cases, since a warrant is recorded in the case it was issued in.
- UJS Web Portal, the Pennsylvania courts' free statewide docket search, for a case whose register of actions shows a warrant.
- The District Attorney, phone (570) 524-8651, which can say whether charges were filed; a warrant on a complaint follows the filing.
Not one of the Union County pages SearchSystems verified (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 Union County
Only the judge who issued a warrant can recall it. For a case from Union County that means appearing before the Union County Court of Common Pleas or the Magisterial District Courts, with the case put back on the calendar through the Prothonotary for civil cases and divorces and the Clerk of Courts for criminal cases.
A missed date in a case before the Magisterial District Courts is handled by that court, not by the Union County Court of Common Pleas.
A lawyer can often arrange the appearance in advance. The District Attorney's page SearchSystems verified is at unioncountypa.org/district-attorney, phone (570) 524-8651.
