Who Issues Warrants in Round Lake Park
In Illinois an arrest warrant is signed by a judge. For Round Lake Park that means the Circuit Court of Lake County, which hears every civil, criminal, family, probate, traffic and juvenile case.
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 Circuit Clerk keeps that file.
For Lake County, SearchSystems opened and checked the court records page for the county at ilsos.gov/departments/archives/databases/lake.html (page title: Lake County Circuit Court Case Files Index (1840-1898)), phone 815-753-1807, which answered when SearchSystems opened it on September 23, 2026.
