Who Issues Warrants in Mundelein
In Illinois an arrest warrant is signed by a judge. For Mundelein that means the Circuit Court of Lake 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.
The court records page SearchSystems verified for the county is 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.
Illinois has no single public index of every trial court case; each court's records are looked up through that court.
