What “free” actually means when searching Illinois criminal records
You can search several types of Illinois criminal-record information without paying, including many county court case indexes, Illinois Department of Corrections offender records and qualifying appellate court documents. But Illinois does not provide one completely free statewide criminal-history background report. Official statewide conviction information is maintained by the Illinois State Police Bureau of Identification and carries a fee under the Uniform Conviction Information Act process.
Which Illinois criminal-record searches are actually free?
The phrase “free Illinois criminal records” can mean very different things. You can often find useful public information at no charge, but a free web lookup should not be confused with an official statewide Illinois criminal-history response.
| Record / service | Free? | What it provides | Main limitation |
|---|---|---|---|
| County Circuit Clerk case lookup | Often yes | Public case number, parties, docket/status and other locally published court information. | Illinois counties use different systems and online coverage varies. |
| Courthouse public-access terminal | Viewing commonly free | Broader courthouse access to qualifying public court records. | Copies or certification may carry fees. |
| IDOC Individual in Custody Search | Yes | Illinois Department of Corrections custody/offender information. | Not a complete statewide criminal-history search. |
| re:SearchIL reviewing-court documents | Yes for qualifying public records | Non-confidential Illinois Supreme and Appellate Court documents covered by current remote-access rules. | Does not mean every Circuit Court criminal document is freely available statewide online. |
| ISP UCIA name-based conviction inquiry | No | Official Illinois State Police conviction-history information released under UCIA. | Published fee applies. |
| Your own ISP Access & Review | ISP processing: no charge | Your Illinois criminal-history transcript and Record Challenge process. | The fingerprinting provider may charge its own fingerprint service fee. |
Identify the record before choosing a database
Criminal court case
Filed charges, docket events, court dates, dispositions, sentencing orders and official case documents.
State criminal history
Conviction information maintained by the ISP Bureau of Identification under the Uniform Conviction Information Act.
Arrest or incident report
Reports generally remain with the local law-enforcement agency or state agency that created the record.
Booking / current detention
Current local jail custody is normally searched county by county rather than through IDOC.
State prison record
Use Illinois Department of Corrections offender tools for people connected to state correctional custody.
Criminal appeal
Illinois Supreme Court and Appellate Court records have separate statewide remote-access options.
How to search Illinois criminal court cases for free
Illinois trial courts are Circuit Courts. The Circuit Clerk is the official keeper of court records for cases filed within that county or judicial circuit.
Illinois has 102 counties, and online public access is not identical in every county. The Illinois Courts website therefore provides two useful official statewide navigation resources:
Find an Illinois Circuit Court Clerk View county e-business links
Identify the county where the criminal case was filed
Start with the county where the arrest, prosecution or alleged offense occurred. A person’s current residence is not necessarily where the court file exists.
Open the official Circuit Clerk website
Use the Illinois Courts clerk directory instead of relying on a third-party people-search website.
Look for “Case Search,” “Public Access” or “Online Court Records”
The wording differs by county. Some portals allow public name and case-number searches; other counties provide more limited electronic access.
Search by case number when possible
A case number is generally safer than relying on a common name. If you search by name, confirm available birth date, court, offense and filing details.
Move to courthouse access if the website is incomplete
Remote access can be more limited than courthouse access. A public court file may still exist even when every document is not available online.
How to find the correct Illinois county court system
If you know the city but not the county, identify the county before searching. This is especially important around Chicago and the suburban collar counties.
Examples of Illinois county criminal-record access
These examples show why Illinois should be searched county by county rather than through one assumed statewide trial-court portal.
Chicago and suburbs
The Clerk of the Circuit Court provides public online case information and courthouse public-access terminals. The Clerk warns that online data is not the official court record.
18th Judicial Circuit
DuPage provides an online Public Information Application supporting case-number, name and other available searches.
12th Judicial Circuit
Will County provides a free Court Case Lookup but specifically describes it as a limited version of the court’s data. More complete access is available at onsite public terminals.
19th Judicial Circuit
Lake County maintains criminal court records and offers an online portal, record-search services and courthouse document-request procedures.
How to read an Illinois criminal case correctly
Finding a person’s name is not enough. Follow the case through its final disposition.
| Case item | What it generally means | What you should check |
|---|---|---|
| Arrest | A law-enforcement event involving custody or arrest. | It does not establish guilt or conviction. |
| Charge / Count | An alleged criminal offense in the case. | See whether it was amended, dismissed or resolved differently. |
| Docket entry | A chronological court event or filing. | Look for motions, pleas, orders, trial and sentencing activity. |
| Disposition | The outcome of a count or case. | Conviction, dismissal, acquittal, supervision or another result. |
| Court supervision | An Illinois disposition that is legally distinct from an ordinary conviction. | Read the exact court record rather than labeling every supervision case a conviction. |
| Sentence | The court-imposed penalty or conditions following a qualifying disposition. | Look for incarceration, probation, fines, credits and later modifications. |
| Expunged / sealed | Access has been restricted under Illinois law and court order. | Do not infer that an absent record never existed. |
How to get an official or certified Illinois court record
The Circuit Clerk for the county where the case was filed is normally the correct source for official copies of the trial-court record.
Personal reference
Appropriate when you only need to read a filing and no agency requires certification.
Proof of outcome
Often requested when another agency needs an official record showing how the criminal case ended.
Judgment or sealing order
Ask for the exact judgment, sentencing order, expungement order or other identified document when possible.
Illinois State Police criminal-history information is different from a court search
The Illinois State Police Bureau of Identification maintains Illinois criminal-history information. Under the Uniform Conviction Information Act (UCIA), conviction information collected and maintained by ISP must be available to the public.
ISP criminal-history information ISP name-based background checks
Illinois UCIA criminal-history fees
This is where the keyword “free Illinois criminal records” needs careful explanation: the official statewide ISP conviction inquiry is not generally free.
| UCIA inquiry | Manual / paper | Electronic / Live Scan | Use |
|---|---|---|---|
| Name-based inquiry | $16 | $10 | Public Illinois conviction-information inquiry using identifying data rather than fingerprints. |
| Fingerprint-card inquiry | $20 | $15 | Fingerprint-based UCIA conviction inquiry. |
| Access & Review | ISP processing: no charge | Used by a person to obtain and review their own Illinois criminal-history transcript. | |
These are ISP’s published Bureau of Identification fees checked in September 2026. A fingerprint vendor can charge an additional service fee even when ISP itself does not charge for the Access & Review process.
Paper UCIA forms
ISP provides an official process for requesting Uniform Conviction Information forms. The UCIA name-based request form may be used by an individual or agency to request non-fingerprint conviction information about a person.
How to get your own Illinois criminal-history transcript
If you want to see what is actually on your own Illinois criminal-history record, use the ISP Access and Review process rather than purchasing an ordinary public conviction inquiry about yourself.
Locate an authorized fingerprint provider
ISP says an individual may use an Illinois law-enforcement or correctional facility that provides the service, or a licensed fingerprint vendor.
Request Access & Review
Tell the provider that you want your Illinois criminal-history transcript through the Access and Review process rather than an employment background check.
Submit fingerprints and identifying information
The provider sends the fingerprints and identifying information to the Illinois State Police.
Receive the transcript or no-record statement
ISP sends your criminal-history transcript and Record Challenge form, or a statement that no criminal history was located.
How to challenge an incorrect Illinois criminal history
ISP’s Access & Review response includes a Record Challenge form. Use it when information on your Illinois criminal-history transcript appears inaccurate or incomplete.
Illinois arrest and police reports usually come from the agency that created them
A statewide ISP conviction-history search is not a substitute for an arrest report, incident report, body-camera video or local police investigation file.
City arrest / incident
Contact the police department that handled the incident and follow that agency’s FOIA procedure.
Sheriff record
Contact the sheriff when its deputies created the report or the record concerns county detention.
ISP-created record
Use the ISP FOIA process when the requested arrest, accident, investigative or other record is maintained by ISP.
How Illinois Freedom of Information Act requests work
Illinois FOIA can be used to request qualifying public records from state and local public bodies. It does not require the government to create a new report or answer research questions for the requester.
Find the correct public body
Send the request to the agency that actually maintains the record. A local police report should not be sent to ISP simply because ISP maintains statewide criminal history.
Describe the record specifically
Ask for an identifiable record rather than “everything concerning John Doe.” Broad “any and all” requests can create avoidable delay or burden issues.
Request inspection or copies
State whether you want to inspect the record, receive electronic copies or obtain paper copies.
Track the response deadline
ISP states that ordinary FOIA requests are subject to a five-business-day response period, with a possible additional five-business-day extension when legally applicable.
| FOIA item | General Illinois rule |
|---|---|
| First 50 black-and-white standard pages | No copying fee under the ordinary statutory fee provision. |
| Page 51 and later | Up to 15¢ per black-and-white letter/legal-size page. |
| Color / unusual-size copies | Public body may generally charge actual reproduction cost. |
| Electronic records | Fees depend on applicable law, medium and request circumstances. |
| Exempt records | FOIA does not override statutory exemptions, court restrictions or protected law-enforcement information. |
Illinois Attorney General FOIA resources Illinois State Police FOIA
County jail and booking records are not the same as IDOC records
Illinois county jails are generally operated locally. Someone arrested recently and being held before trial may appear in a county sheriff’s inmate system but not in Illinois Department of Corrections search results.
Illinois warrant information is usually local
Illinois does not operate one simple general-public statewide web page listing every active arrest warrant issued by every Circuit Court.
A warrant question may require checking with:
- the Circuit Clerk for the underlying case
- the county sheriff’s warrant unit
- the police agency handling the warrant
- the issuing court
- another county if the case originated elsewhere
- federal authorities when it is a federal warrant
Search-warrant records may be restricted
Search-warrant access is not necessarily the same as ordinary criminal case access. Local court rules can require warrant materials to be impounded or withheld unless the court orders access. Always check the issuing Circuit Court’s current local rules before assuming a warrant affidavit is public.
Illinois Department of Corrections offender search
The Illinois Department of Corrections provides a free Offender Search area containing multiple public lookup tools.
Current IDOC search resources include:
- Individual in Custody Search
- Wanted Fugitives
- Illinois Sex Offender Information links
- Parolee Sex Registrant Search
- early-release community notifications
- other custody-related public information
Illinois sex offender information is a separate record system
Illinois maintains public sex-offender information separately from general court cases, ISP UCIA conviction inquiries and IDOC custody information.
Court-document requests should be directed to the county Circuit Clerk or appropriate State’s Attorney, while incident reports should be directed to the law-enforcement agency involved in the arrest.
Illinois appellate and Supreme Court records now have broader free remote access
Illinois’s reviewing courts include the Illinois Supreme Court and five Appellate Court districts. Their remote-access situation differs from county Circuit Court criminal records.
Beginning May 1, 2025, the Illinois Supreme Court authorized free remote public access through re:SearchIL to qualifying non-confidential reviewing-court documents filed on or after April 1, 2025.
Not every document is available. Confidential records and certain materials, including portions of the circuit-court record on appeal, can remain unavailable remotely.
What to do when an old Illinois criminal case is missing online
Online coverage varies significantly among Illinois counties. A case can still be part of the public court record even when the county website does not show it.
Illinois expungement and sealing can change what appears publicly
Illinois distinguishes between expungement and sealing. The eligibility rules depend on arrest history, disposition, supervision, conviction type, waiting period and other circumstances.
The Illinois Office of the State Appellate Defender provides statewide instructions and Supreme Court-approved forms that courts must accept.
Illinois expungement & sealing guide
Removes qualifying records
Illinois describes expungement as erasing or physically destroying qualifying records, returning them where applicable and removing identifying information from official public indexes.
Restricts public access
A sealed record is generally hidden from the ordinary public even though qualifying government and criminal-justice entities may retain legally authorized access.
Where to file
People with qualifying Illinois arrests or convictions generally petition in the court of the county connected to the relevant case. Illinois provides statewide approved forms, but filing procedures and local fees should be confirmed with the applicable Circuit Clerk.
| ISP item | Current published fee |
|---|---|
| Petition to expunge or seal criminal history | No ISP charge listed |
| Court order to expunge or seal criminal history | $60 ISP processing fee |
Court filing fees are separate from ISP’s criminal-history processing fee schedule and can vary. Fee waivers may be available for qualifying filers.
Illinois juvenile records have stronger access restrictions
Juvenile records should not be treated like ordinary adult criminal records. Juvenile case information can be sealed, confidential or otherwise restricted under Illinois law and court-access policy.
Federal criminal cases in Illinois use federal systems
Illinois Circuit Court records, ISP criminal-history information and IDOC offender records do not substitute for federal court records.
PACER
Use PACER for public federal District Court, Circuit Court of Appeals and other federal case records.
FBI Identity History Summary
A person requesting their own FBI Identity History Summary follows the FBI’s fingerprint-based process.

Illinois criminal-record search tips that save time
Start with the county
Illinois trial records are decentralized. Knowing the county usually matters more than finding a generic statewide court website.
Use free court lookup first
If you only need a known case, the local Circuit Clerk may answer the question without paying for an ISP UCIA search.
Know what UCIA gives you
The public ISP process provides conviction information, not every police report or non-conviction event.
Use your own Access & Review
If you want to audit your own state record, use ISP’s fingerprint-based Access & Review process.
Remote access can be narrower
A courthouse terminal or clerk request can reveal public information that is not available remotely.
Do not confuse jail with IDOC
A recent county detainee belongs in a sheriff or jail search; IDOC covers state correctional custody.
Get the disposition
When accuracy matters, read the final disposition rather than reporting only the original arrest charge.
Search former names separately
An ISP UCIA name inquiry is tied to the submitted name. Former or maiden names can require separate searching.
Check archived records
Older Illinois cases may exist at the courthouse even when the county’s current online portal does not show them.
Using Illinois criminal records for employment or housing decisions
A free court lookup, sheriff inmate page, IDOC offender record or informal public-record search is not automatically equivalent to a legally compliant consumer background report.
Frequently asked questions about free Illinois criminal-record searches
1. Can I search Illinois criminal records for free?
Yes, some records can be searched without charge. Many Illinois counties provide free public court case lookups, IDOC offender search is free, and qualifying reviewing-court documents are available free through re:SearchIL. However, the official Illinois State Police statewide UCIA conviction inquiry carries a fee.
2. Is there one free statewide Illinois criminal court database?
No single public trial-court portal should be treated as a complete free statewide criminal-case search for all 102 Illinois counties. Use the Illinois Courts Circuit Court Clerk directory and county e-business links to locate the appropriate local system.
3. How much is an Illinois State Police name-based conviction search?
ISP currently lists a UCIA name-based inquiry at $16 when submitted manually on paper and $10 when submitted electronically through an eligible electronic process.
4. Can I get my own Illinois criminal history for free?
Illinois State Police does not charge a processing fee for its Access & Review / Record Challenge process. However, the law-enforcement agency or licensed vendor that takes your fingerprints may charge a fingerprinting service fee.
5. Does an ISP UCIA public search show every arrest?
No. The Uniform Conviction Information Act public process is for conviction information maintained by ISP. It is not a complete release of every arrest, dismissed charge, police report or juvenile record.
6. Where do I search Illinois county jail inmates?
Use the official sheriff or detention agency for the county where the person is being held. County jail custody is separate from Illinois Department of Corrections state-prison custody.
7. Where can I search Illinois prison records?
Use the Illinois Department of Corrections Offender Search and its Individual in Custody Search for qualifying state correctional information.
8. How do I correct an Illinois criminal-history error?
Obtain your record through ISP Access & Review and use the included Record Challenge process. Supporting court documentation can help when the error concerns a missing or incorrect disposition.
9. Can Illinois criminal records be expunged or sealed?
Yes, qualifying Illinois arrests, dispositions and certain convictions may be eligible for expungement or sealing. Eligibility depends on the type of record and applicable Illinois law. The Office of the State Appellate Defender provides statewide instructions and approved forms.
10. Are Illinois appellate court records available online for free?
Qualifying non-confidential Illinois Supreme Court and Appellate Court documents filed under the current reviewing-court remote-access rules are available free through re:SearchIL. This does not mean every Circuit Court trial document is freely available statewide online.
