Who Issues Warrants in Union County
In Oregon an arrest warrant is signed by a judge. For Union County that means the Union County Circuit Court, which hears every civil, criminal, family, probate and juvenile case. A city with a municipal and justice court of its own issues warrants on the tickets and ordinance cases it tries.
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 trial court administrator keeps that file.
For Union County, SearchSystems opened and checked the court records page for the county at courts.oregon.gov/courts/union/records/pages/default.aspx (page title: Oregon Judicial Department : Court Records | Home : Court Records : State of Oregon), which answered when SearchSystems opened it on September 24, 2026.
