Who Issues Warrants in Union County
In Illinois an arrest warrant is signed by a judge. For Union County that means the Circuit Court of Union County, which hears every civil, criminal, family, probate, traffic and juvenile case.
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 Circuit Clerk.
For Union County, SearchSystems opened and checked the court records page for the county at illinoiscourts.gov/courts-directory/146/Union-County-Courthouse/court (page title: Union County Courthouse | State of Illinois Office of the Illinois Courts), phone (618) 833-8114, which answered when SearchSystems opened it on September 23, 2026. That page belongs to a lower court, not to the Circuit Court of Union County.
