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

How to Check for a Warrant in LaSalle County
Whether a warrant is out from LaSalle County shows in two places:
- The State's Attorney, phone 815-434-8340, which can say whether charges were filed; a warrant on a complaint follows the filing.
- The custody page of the La Salle County Sheriff's Office at lasalleso.com/inmateSearch, which shows people already arrested and booked, not open warrants.
Not one of the LaSalle County pages SearchSystems verified (the sheriff's, the prosecutor's and the records request page) 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 LaSalle County
Only the judge who issued a warrant can recall it. For a case from LaSalle County that means appearing before the Circuit Court of LaSalle County, with the case put back on the calendar through the Circuit Clerk.
A lawyer can often arrange the appearance in advance. The State's Attorney's page SearchSystems verified is at lasallecountyil.gov, phone 815-434-8340.
