Winnebago County Circuit Court Clerk

Tom Klein serves as the Winnebago County Circuit Court Clerk. The office is at 400 West State Street, Room 100, Rockford, IL 61101-1221. Phone: 815/319-4500, fax: 815/987-3012.

The clerk's office keeps records for all case types filed in the 17th Circuit: felony and misdemeanor criminal cases, traffic matters, civil suits, and family court. For criminal records, the file includes the charging document, case history, court dates, all orders entered during the case, and the final judgment. Staff at the Rockford courthouse can help you locate a specific case if you have a name or case number.

The public has a right to inspect these records under 705 ILCS 105, the Clerks of Courts Act. View a file at no charge; pay a per-page fee only if you need copies. No account, membership, or stated reason is required to access public court records.

Online Case Search Tools

Winnebago County is part of the Judici.com network, which covers 82 of Illinois' 102 counties. Through Judici you can run a free name-based or case-number search of Winnebago County court records, see charges and case status, and check upcoming hearing dates. No registration is required. The data comes directly from the clerk's system and is usually current within a short delay.

For appellate-level records, the re:SearchIL portal provides free public access to Illinois reviewing court records as of May 1, 2025. Winnebago County criminal cases that were appealed fall under the Second Appellate District. Re:SearchIL is the right tool for finding those records. It does not include trial court records, which remain in the local clerk's system.

The main Illinois Courts website is a reliable starting point for understanding the state court system and locating specific resources. It also has the Circuit Clerk Directory listing contacts for all 102 counties, which is helpful when you're tracking records across county lines.

The Illinois Courts website offers court structure information, links to clerk contacts, and guidance on public access to court records for Winnebago County and all other Illinois judicial circuits.

In-Person Access and Mail Requests

Walk-in access is available at Room 100 of 400 West State Street in Rockford. Bring the subject's full name and date of birth. A case number helps but is not required. Staff will locate the case in their system and allow you to view it. If you need paper copies of documents in the file, pay the applicable per-page fee at the counter.

Mail requests work the same way in terms of what information to include: full name, approximate year, date of birth, case number if available. Write to 400 West State Street, Room 100, Rockford, IL 61101-1221. Fax: 815/987-3012. The clerk's office will confirm what they found and let you know the cost for copies. Allow one to two weeks for a written response. For urgent requests, calling 815/319-4500 first is often faster.

Statewide Criminal History Checks

Court records from Winnebago County cover only cases filed in that county. For a complete picture of someone's Illinois criminal history, use the Illinois State Police Bureau of Identification. ISP BOI aggregates conviction records from all 102 Illinois counties. You can order a name-based conviction check online at isp.illinois.gov/BureauOfIdentification/BackgroundChecks, or request a fingerprint-based check through ISP BOI at 260 N. Chicago St., Joliet, IL 60432, phone 815/740-5160.

The Uniform Conviction Information Act (20 ILCS 2635) governs the statewide conviction database. Under this law, conviction records are public, but arrests that did not lead to conviction are not broadly available to third parties. Individuals can review their own full history through the CHIRP portal free of charge. Employers and licensing boards typically use ISP's official background check process rather than court record searches.

The CHIRP system lets Winnebago County residents review and challenge their own Illinois criminal history record at no cost, covering conviction data from the county and all other Illinois jurisdictions.

Criminal Court Records: What Is Open and What Is Not

The default in Illinois is that criminal court records are public. Charging documents, court orders, plea agreements, sentencing records, and hearing logs are all accessible to anyone who asks. The Court Record and Document Accessibility Act (705 ILCS 86) makes public access the presumption, and the Clerks of Courts Act backs that up with the right to inspect at no charge.

Several categories are closed. Juvenile delinquency records are sealed under state law. If a court has ordered an adult record sealed or expunged, it disappears from public view. That includes the clerk's own portal, Judici, and any other public database. Adoption files are not public. Social Security numbers, account numbers, and similar personal data are stripped from copies provided to the public, even when the case itself is open.

Illinois courts are exempt from the state Freedom of Information Act under 5 ILCS 140. If you try to submit a FOIA request to the Winnebago County clerk, it will be declined on jurisdictional grounds. The proper method is the clerk's public access process, which is governed by court rules and the Clerks of Courts Act.

Electronic Filing in Winnebago County

Winnebago County participates in eFileIL, the statewide mandatory e-filing platform. Most attorneys are required to use it. Self-represented criminal defendants may have different requirements depending on the case type. The clerk's office at 815/319-4500 can clarify what's required before you file. EFileIL is not a public search tool; it handles submissions only. For records searches, use Judici or the clerk's own portal.
