To run a Cook County criminal case lookup, use the Clerk of the Circuit Court’s free online case search at casesearch.cookcountyclerkofcourt.org, or visit any of the county’s courthouses in person. Either route pulls from the same database, and both are open to the public because Illinois courts operate under a presumption of access set by Illinois Supreme Court Rule 8 rather than the state’s Freedom of Information Act.1Clerk of the Circuit Court of Cook County.

What to Have Ready Before You Search
A case number is the fastest way in. Cook County criminal case numbers use the last two digits of the filing year, then “CR,” then a seven-digit sequence, so a case filed in 2025 looks like 25-CR-1234567.2Circuit Court of Cook County. General Order 6.2 – Numbering of Actions
If you don’t have the number, you can search by name. Use the defendant’s full legal name, add a middle initial when the surname is common, and have a date of birth handy to confirm you’re looking at the right person.
It also helps to know which municipal district handled the case. Cook County runs six districts: the First covers Chicago, and the other five sit in Skokie, Rolling Meadows, Maywood, Bridgeview, and Markham.3Circuit Court of Cook County. Organization of the Court The district usually tracks where the arrest or citation happened, and that detail typically appears on the original paperwork.
Looking Up a Case Online
The Clerk’s online portal lets you search by case number or by name. Results come from the same system the courthouses use, and it works for both active and closed cases.1Clerk of the Circuit Court of Cook County. On-line Case Information
What you’ll see is the electronic docket: a chronological log of short entries covering the filings and events in the case. That means charges, court dates, motions, and orders entered by the judge. The docket shows where things stand and how the case moved, but it doesn’t include images of every document in the physical file. Blank fields usually mean the Clerk’s master database doesn’t hold that data point.1Clerk of the Circuit Court of Cook County. On-line Case Information
Looking Up a Case in Person
The main courthouse is the Richard J. Daley Center at 50 West Washington Street in Chicago. The suburban courthouses sit in Skokie, Rolling Meadows, Maywood, Bridgeview, and Markham.4Cook County Government. Court Address Each has public terminals that search the same database as the online portal. On-site kiosks sometimes surface older records that haven’t been fully digitized.
For files that only exist in paper form, ask at the Clerk’s counter. Staff will pull the file for you to review on-site. If you need a version you can use for legal or employment purposes, ask for a certified copy, which carries the Clerk’s raised seal.
Copy and Search Fees
A record search costs $6.00 for each year searched in the indices, paid upfront. Certified copies cost $6.00 per document, plus copying and mailing charges. Uncertified photocopies follow the Illinois statutory schedule: $2.00 for the first page, $0.50 each for pages two through nineteen, and $0.25 per page after that.5Clerk of the Circuit Court of Cook County. Archives Department Courthouses typically take cash, credit card, or money order.
What You Won’t Find
Not every criminal record in Cook County is public. Illinois Supreme Court Rule 8 lets the court restrict access by classifying records as impounded, confidential, sealed, or expunged, and remote access is further limited to what the Illinois Supreme Court Remote Access Policy allows.
Juvenile Cases
Under 705 ILCS 405/1-7, juvenile law enforcement records that haven’t been expunged are confidential and may not be disclosed to the general public. Only a specific list of authorized parties can see them, and anyone else needs a court order showing good cause.6Illinois General Assembly. Illinois Code 705 ILCS 405/1-7 – Confidentiality of Juvenile Law Enforcement and Municipal Ordinance Violation Records If you’re looking for a case involving a minor, the system will act as though the record doesn’t exist.
Sealed and Expunged Cases
The two are different under Illinois law. Expungement means the records are physically destroyed or returned to the petitioner and the person’s name is removed from official indices. Sealing keeps the records intact but hides them from the general public without a court order, while leaving them accessible to law enforcement and certain authorized agencies. In either case, when an unauthorized person inquires, the responding agency must answer as though no record ever existed.
Redactions in Domestic Violence, Sexual Assault, and Stalking Cases
The federal Violence Against Women Act bars entry of victims’ personally identifying information into public records and databases. Programs receiving VAWA funding can’t release a victim’s identifying details without informed, written, time-limited consent. Documents in these cases may show up partially or fully redacted.
A Warning About Third-Party Background Sites
Many private websites advertise Cook County criminal records, and their accuracy is a real problem. A peer-reviewed study comparing official state criminal records against private-sector background checks found that a majority of subjects had at least one false-positive error, meaning someone else’s record was attributed to them, and nearly all subjects had false-negative errors from missing disposition data. The industry pulls from fragmented and outdated sources, and the results reflect that.
If you need reliable information about a Cook County case, use the Clerk’s portal or go to a courthouse. Third-party results can point you in a direction, but treating them as definitive causes real harm in hiring, housing, and personal decisions.
If a Background Check Shows a Cook County Record You Want to Dispute
A lot of people run this search because something surfaced on an employer’s background report. If the report contains a Cook County case that isn’t yours, shows charges without a disposition, or reflects a record that was sealed or expunged, you have the right to dispute it under the Fair Credit Reporting Act. The background check company must reinvestigate and correct or delete anything inaccurate, incomplete, or unverifiable. You don’t need special legal language to ask for your file or file a dispute.7Consumer Financial Protection Bureau. CFPB Addresses Inaccurate Background Check Reports and Sloppy Credit File Sharing Practices
Start by requesting your complete file from the company that ran the check. They must provide it in a form that lets you identify inaccuracies, including all sources. Put the specific errors in writing and submit the dispute to the reporting company. If they don’t investigate or correct the record, file a complaint with the Consumer Financial Protection Bureau at consumerfinance.gov/complaint.
You also have a right to see the report before an employer takes final adverse action against you. Under 15 USC 1681b, an employer planning to reject you based on a background check must first give you a copy of the report and a written statement of your rights, so you can flag errors before the decision is made.8Office of the Law Revision Counsel. 15 USC 1681b – Permissible Purposes of Consumer Reports After an adverse action, the employer must also give you the background company’s name and contact information, a statement that the company didn’t make the hiring decision, and notice of your right to dispute the report and get a free copy within 60 days.9Federal Trade Commission.
