Tinley Park Criminal Court Records

Tinley Park criminal court records are held by the Circuit Court Clerk of either Cook County or Will County, depending on where in the city the incident took place. Most of Tinley Park falls within Cook County, but a portion of the city sits in Will County, and that split matters when you need to find a specific case. This guide explains how each county handles criminal filings, what you can search online, and where to go for help if you run into a dead end.

Which County Filed the Case

The county that filed a criminal case against someone in Tinley Park depends on where the offense happened, not where the defendant lives. If the incident occurred in the Cook County portion of Tinley Park, Cook County Circuit Court handles it. If it happened in the Will County portion, it goes to Will County Circuit Court in Joliet. This is a key distinction, and it trips up a lot of people searching for records.

Tinley Park's Cook County section covers most of the city, including the downtown area and the bulk of residential streets. The Will County section is along the southern and eastern edges of the city. When in doubt, the Tinley Park Police Department can tell you which jurisdiction handled a particular incident. Their records division can point you in the right direction before you make a trip to a courthouse.

Both counties participate in the statewide re:SearchIL system, which went free on May 1, 2025. That said, Cook County is an exception for criminal cases. See the Cook County section below for details on that important limitation.

Cook County Circuit Court - Criminal Records Access

Cook County Circuit Clerk Mariyana T. Spyropoulos oversees the largest court system in Illinois. The office is at 50 W. Washington, Suite 1001, Chicago, IL 60602. Phone: 312/603-5030. The website is at cookcountyclerkofcourt.org.

Cook County criminal court records are not available online. This is a firm policy, and it applies to all criminal case types in Cook County, from misdemeanors to felonies. If you need a Cook County criminal record from the Tinley Park area, you must appear in person at a Cook County courthouse. The courthouse that handles criminal cases for the Tinley Park area is the Markham Courthouse at 16501 S. Kedzie Parkway, Markham, IL 60428. That is the courthouse for Cook County's 5th Municipal District, which covers the south suburban area where Tinley Park sits.

When you go in person, bring the defendant's full name and any case number you have. Staff at the clerk's window can pull up the record and give you copies for a per-page fee. Under 705 ILCS 105, court records are public documents, and the clerk is required to provide access to non-sealed files upon request.

Will County Circuit Court - Criminal Records Access

If the Tinley Park case was filed in Will County, the Circuit Clerk is Andrea Chasteen. The office is at 100 West Jefferson Street, Joliet, IL 60432. Phone: 815/727-8592. Will County uses Judici.com for online case access, which makes searching much simpler than Cook County.

The screenshot below shows the Judici platform, which Illinois counties including Will County use to provide free public access to criminal and civil case records.

On Judici, you can search by name or case number and get case details including charges, court dates, and dispositions. Will County criminal cases are also part of re:SearchIL. Both tools are free. You can also call the Will County clerk's office directly to confirm whether a particular case is in their system.

What Criminal Court Records Contain

A criminal court file in either Cook or Will County typically includes the same core documents. You will find the charging documents (complaint, indictment, or information), the defendant's name and identifying details, a list of charges with statute citations, all court appearance dates, motions filed by both sides, any plea agreement entered, and the final verdict or sentence if the case concluded.

Some records are not public. Sealed cases do not appear in any public search. Records involving juveniles are also not available to the general public. Expunged records are removed from the index entirely. If a search comes up empty, those are two reasons it might happen. It could also mean the case was filed in a different county than the one you searched.

Under 20 ILCS 2635, the Unified Crime Information Act sets out how conviction data is collected and shared at the state level. That statute also governs what types of records can be reported by the Illinois State Police.

Illinois State Police Bureau of Identification

The ISP Bureau of Identification keeps statewide criminal history records. If someone was charged and convicted anywhere in Illinois, that record may appear in a BOI background check. The BOI office is at 260 N. Chicago Street, Joliet, IL 60432. Phone: 815/740-5160.

The screenshot below shows the ISP Bureau of Identification's page, where you can find background check request forms and fee information.

Name-based checks are available to the general public. They are less thorough than fingerprint-based checks, since a name search can miss records filed under slightly different names or aliases. If you need a complete criminal history for official purposes, a fingerprint-based check through BOI is more reliable. Fingerprint-based checks are used for licensing, professional certifications, and similar official requirements.

Re:SearchIL Statewide Court Portal

Re:SearchIL is Illinois's unified court records system. As of May 1, 2025, access is free for the public. The portal covers most Illinois counties and allows name-based searches across multiple courts at once.

The screenshot below shows the re:SearchIL portal, the central system for searching Illinois criminal and civil court records statewide.

Keep in mind the Cook County limitation. Criminal cases filed in Cook County do not appear in the re:SearchIL public search. For Will County Tinley Park cases, though, re:SearchIL works well. You can search by name, filter by court, and get case details without any fee. It is a good first stop when you do not know which specific county court handled a case.
