Find Criminal Court Records in Naperville

Naperville criminal court records are primarily filed with the DuPage County Circuit Court Clerk, since most of Naperville falls within DuPage County. A smaller portion of the city extends into Will County, so some cases are handled by the Will County Circuit Court Clerk in Joliet. Knowing which county handled a specific case is the first step before you try to search or request records. This page covers how to search online, who to contact, and what the records contain.

How to Search Naperville Criminal Records Online

DuPage County participates in both Judici and re:SearchIL, which means you can search most Naperville criminal court records online at no cost. Both tools are free to use and do not require an account for basic searches.

Judici is a third-party service used by 82 of Illinois's 102 counties. It lets you search by name or case number and see basic case information including charges, court dates, and dispositions. The screenshot below shows the Judici platform, which covers DuPage County cases.

re:SearchIL went live statewide on May 1, 2025. The screenshot below shows the re:SearchIL portal. It provides another free way to access DuPage County criminal case records. You can filter by county to narrow your results to Naperville cases.

If you cannot find what you need online, contact the DuPage County Circuit Clerk's office directly. Staff can help confirm whether a case exists and whether it falls in DuPage or Will County.

Cases from the Will County portion of Naperville go to Will County Circuit Court. The clerk is Andrea Chasteen. Office address: 100 West Jefferson Street, Joliet, IL 60432. Phone: 815/727-8592. Website: willcountyillinois.com/circuit-clerk.

Will County also uses Judici and re:SearchIL for online access. If you are searching for a Naperville case and it does not appear in DuPage County results, try searching Will County as well. The county that filed the case depends solely on where the incident happened, not on the defendant's address within Naperville.

What Is in a Criminal Court File

A criminal court file for a Naperville case typically contains the charging document, which lists the specific charges and the statutes cited. It also includes the defendant's name, date of birth, and case number. You will find a docket sheet that lists every court appearance. The file has orders from the judge, motions filed by both the defense and prosecution, and any plea agreement if the case settled without a trial.

If the case went to trial, the verdict is part of the record. If the defendant was sentenced, the sentencing order is included. Dismissed charges are also noted. Not all records are available publicly. Sealed and expunged records are removed from public view. Juvenile records are confidential by default under Illinois law. Mental health evaluations ordered by the court may be restricted as well.

If you search online and a record does not appear, it may be sealed. Or the case may have been filed in the other county. It is worth checking both DuPage and Will County before concluding a record does not exist.
