Illinois Public Records: A Complete Research Guide

Illinois public records are government-created documents, filings, databases, and communications maintained by state and local agencies that are generally accessible to the public under the Illinois Freedom of Information Act (FOIA), codified at 5 ILCS 140/1 et seq. Originally enacted in 1984 and substantially overhauled in 2010, FOIA establishes a presumption that all records in the possession of a public body are accessible to any person unless a specific exemption applies.

Residents frequently perform an Illinois public records search — sometimes called an Illinois FOIA request, Illinois public records lookup, or Illinois open records request — to locate court filings, criminal conviction records, property ownership information, business registrations, and vital records.

Public records in Illinois are distributed across state agencies and 102 county-level systems, with no single statewide portal covering all record types. Chicago and Cook County operate their own parallel systems for many records that differ significantly from the rest of the state. Understanding which agency maintains each record type — and whether Cook County requires a different approach — is the key to researching public records effectively in Illinois.

  • Cook County Circuit Court Case Search (casesearch.cookcountyclerkofcourt.org) — online docket search for Cook County cases (civil, probate, traffic; criminal limited)
  • Illinois Supreme Court and Appellate Courts (illinoiscourts.gov) — published opinions and appellate case information
  • Illinois State Police CHIRP — Criminal History (isp.illinois.gov/BureauOfIdentification) — UCIA conviction-only name search
  • Illinois Sex Offender Registry (isp.illinois.gov/SexOffender) — free statewide Megan’s Law registry
  • Illinois DOC Inmate Search (idoc.illinois.gov) — state prison inmate records
  • Cook County Property Tax Portal (cookcountypropertyinfo.com) — unified property tax, assessment, and recorded document search for Cook County
  • Illinois Secretary of State Business Search (ilsos.gov/corporatellc) — statewide business entity registrations
  • Illinois IDPH Vital Records (dph.illinois.gov) — birth and death certificates via mail or VitalChek
  • Illinois IDFPR License Lookup (idfpr.illinois.gov) — professional license verification
  • Illinois Attorney General FOIA portal (illinoisattorneygeneral.gov/pac) — FOIA guidance, Public Access Counselor contacts, and PAC request submission

These systems provide access to the majority of publicly searchable government records in Illinois.


Illinois public records law is governed primarily by the Illinois Freedom of Information Act (5 ILCS 140) and the Illinois Open Meetings Act (5 ILCS 120). While all records of public bodies are presumed accessible, common exemptions include personal privacy information, preliminary draft materials, law enforcement investigative records, trade secrets, and certain categories of criminal justice data. Criminal conviction records are separately governed by the Uniform Conviction Information Act (20 ILCS 2635), which makes conviction data — but not arrests or non-conviction records — publicly available. Vital records are governed by the Illinois Vital Records Act (410 ILCS 535) and are not subject to FOIA.

Why Illinois Public Records Law Is Distinctive

Illinois operates under a public records framework that was once among the weakest in the country and was substantially reformed in 2010 into one of the more robust state systems. Several features distinguish the current Illinois FOIA from other states.

Illinois was the last state to enact a freedom of information law. FOIA was first introduced to the Illinois General Assembly in 1974 but faced repeated resistance before finally passing in 1984 — a decade after most other states had enacted open records laws. The 2010 overhaul transformed the law significantly, adding the Public Access Counselor position, mandatory training requirements for public body FOIA officers, and binding enforcement authority. The history of resistance makes Illinois’s current framework all the more notable.

The Public Access Counselor can issue binding opinions with the force of administrative law. The Illinois Attorney General’s Public Access Counselor (PAC) is the enforcement body for FOIA disputes. When a requester submits a Request for Review, the PAC can issue a binding opinion — treated as a final administrative agency decision subject to judicial review — that compels a public body to disclose records. This is meaningfully stronger than New York’s Committee on Open Government (advisory opinions only) and Florida’s AG mediation program (voluntary). In 2024, the PAC received over 4,200 complaints and issued more than 200 binding opinions. The PAC also has a public hotline at 877-299-3642.

The first 50 pages of any response must be provided free of charge. Illinois FOIA uniquely mandates that public bodies provide the first 50 pages of black and white copies at no cost to the requester. Additional pages may be charged at the actual cost of reproduction. This provision reduces the fee barrier for moderate-sized requests and makes Illinois more accessible than Pennsylvania ($0.25 per page from page one) or Florida (no free pages at all).

Response timelines are short and strictly structured. Illinois agencies must respond within five business days. A single extension of up to five additional business days may be taken in limited circumstances — unusual volume, need for legal review, or records stored off-site. A second extension requires the agency to send a written explanation. Failure to respond within five days constitutes a denial that can be immediately submitted for PAC review. At ten business days total, Illinois has one of the shortest maximum response windows of any state.

FOIA covers a broad range of public bodies. Illinois FOIA explicitly covers state agencies, units of local government, school districts, community college districts, public universities, and any other governmental entities. The 2010 amendments extended clear coverage to electronic records — emails, text messages, and other digital communications are expressly subject to FOIA as long as they relate to official business.

Willful violations carry the highest civil penalty structure of any guide state. A court finding a willful and intentional violation of FOIA may impose a civil penalty of $2,500 to $5,000 per violation, plus attorney fees and costs, against the public body. This is the strongest statutory penalty structure of any state covered in this guide series — Florida’s §119.12 awards attorney fees but no per-violation penalties; Pennsylvania’s OOR can award fees but not civil fines.

Conviction records are public under a separate statute; arrests are not. The Uniform Conviction Information Act (UCIA, 20 ILCS 2635) mandates that all criminal conviction information maintained by the Illinois State Police be available to the public. This makes conviction data accessible to anyone — not just employers or licensed agencies. However, arrest records, non-conviction records, and pending charge information that did not result in a conviction are explicitly not public under UCIA. This creates a sharper public/non-public divide than most states, and it means court records (which show all case activity) are often more useful than UCIA searches for investigative purposes.

Illinois Court Records

Illinois court records document civil, criminal, family, probate, small claims, and traffic cases filed in Circuit Courts — the trial courts of general jurisdiction in Illinois. The state has 24 judicial circuits covering all 102 counties. Cook County, which includes Chicago, operates the largest Circuit Court in the country and maintains its own separate online systems that differ significantly from the rest of the state. There is no single statewide portal that covers all Illinois counties, making court record research in Illinois more fragmented than in states like Pennsylvania (UJS covers all 67 counties).

Judici — Multi-County Circuit Court Search

URL: judici.com
Cost: Free for basic case information; fees for some document images

Judici is the primary online portal for circuit court case information outside Cook County. It provides access to case dockets for participating counties — currently covering a significant but incomplete portion of Illinois’s 102 counties. Search by party name, case number, or attorney. Results include case type, filing date, parties, docket entries, and court dates. Not all counties participate in Judici, and coverage and depth vary. For non-participating counties, contact the county circuit clerk directly.

Cook County Circuit Court — Online Case Search

URL: casesearch.cookcountyclerkofcourt.org
Cost: Free for electronic docket search

The Clerk of the Circuit Court of Cook County provides a public online case search covering civil, probate, traffic, small claims, county division, and mortgage foreclosure matters. Cook County criminal cases are available online for docket information — case status, charges, and appearance dates — but full criminal case documents are not available remotely per the Illinois Supreme Court’s Electronic Access Policy. Criminal records in Cook County must be accessed in person at the clerk’s office district where the case was filed. The Cook County clerk’s main office is at 50 W. Washington, Chicago, IL 60602, phone (312) 603-5030.

An important note: In 2020, the Cook County Recorder of Deeds office merged into the Cook County Clerk’s office. The Clerk now handles both judicial records and land records for Cook County.

Illinois Supreme Court and Appellate Courts

URL: illinoiscourts.gov
Cost: Free

The Illinois Courts website provides access to published opinions from the Illinois Supreme Court and five Appellate Court districts, along with court rules, administrative orders, and general court system information. Opinions are searchable by party name, docket number, or topic.

Federal Court Records

Federal cases filed in Illinois — including bankruptcy, civil rights, and federal criminal matters — are maintained by the U.S. District Courts. Illinois has three federal judicial districts: the Northern District (Chicago, Rockford), the Central District (Springfield, Peoria, Urbana), and the Southern District (East St. Louis, Benton). Federal court records are searchable through PACER (pacer.gov), which requires free registration and charges $0.10 per page for documents.


Illinois Criminal Records

Illinois criminal history is maintained by the Illinois State Police (ISP), Bureau of Identification (BOI), which serves as the state repository under the Criminal Identification Act (20 ILCS 2630). What is publicly available is governed by a separate statute — the Uniform Conviction Information Act (UCIA, 20 ILCS 2635) — which mandates that conviction records be public but explicitly excludes arrests, non-conviction records, and pending charges from public access. This is one of the sharpest public/non-public distinctions in criminal records access of any state covered in this guide series.

UCIA Conviction Search — CHIRP (Name-Based)

URL: isp.illinois.gov/BureauOfIdentification/NameBased
Cost: $16 for a manual name-based inquiry; electronic searches approximately $10

The Illinois State Police’s Criminal History Information Response Process (CHIRP) provides name-based public access to conviction information under the UCIA. Any person may request a conviction search — not just employers or licensed agencies. CHIRP requires registration with an Illinois Digital ID (tied to an Illinois driver’s license). Results cover conviction data only — felonies and misdemeanors that resulted in a finding of guilt. Arrests, dismissed charges, pending cases, and non-conviction dispositions are not included in public UCIA results.

For researching a subject’s court history including pending cases and non-conviction records, the Judici or Cook County case search portals will show more complete case information than a UCIA search, because court records are not limited by the conviction-only restriction.

UCIA Fingerprint-Based Search

Cost: Approximately $15–$20 for electronic submission through an authorized Live Scan vendor

Fingerprint-based UCIA searches provide more definitive identification than name-based searches and are recommended for employment and licensing purposes. Live Scan fingerprint vendors are licensed through the state and listed at the ISP website. Results are mailed from ISP and typically received within 15 days.

Illinois Sex Offender Registry

URL: isp.illinois.gov/SexOffender
Cost: Free

The Illinois State Police maintains the public sex offender registry under the Illinois Sex Offender Registration Act. Search by name, city, county, zip code, or compliance status. The registry is updated daily and includes photographs, current address, conviction information, and registration tier.

Arrest Records and Court-Based Criminal Research

Arrest records — including charges that did not result in conviction — are not public records under UCIA and are not available through the ISP. For arrest and charging information, researchers should use court case search portals: Judici for most counties outside Cook, and the Cook County Circuit Court case search for Cook County matters. Note that Cook County criminal case documents (not just dockets) require in-person access at the relevant district courthouse.

What Is Not Public

  • Arrest records and non-conviction information (explicitly excluded from UCIA public access)
  • Sealed and expunged records (removed from all public access upon court order)
  • Juvenile delinquency records
  • Records of acquittals and dismissed charges
  • Pending charges that have not resulted in a conviction

Illinois Property Records

Illinois property records are maintained at the county level. Each county has a Recorder of Deeds (or, in Cook County, the function is now handled by the County Clerk) that maintains recorded property instruments — deeds, mortgages, liens, and other documents. Each county also has a County Assessor (or Township Assessors in Cook County’s complex multi-layer system) that maintains ownership, valuation, and tax data. These are two separate offices with separate online portals in most counties.

Cook County — Property Tax Portal and Land Records

Property Tax Portal URL: cookcountypropertyinfo.com — Free unified search
Land Records (Recorder/Clerk) URL: cookcountyclerkil.gov/recordings/search-recordings — Free
Assessor URL: assessorpropertydetails.cookcountyil.gov — Free

Cook County’s property record system is unusually complex. The Cook County Property Tax Portal combines data from the Assessor, Treasurer, Clerk, and Board of Review into a single interface — this is the most efficient starting point for Cook County property research. For recorded documents (deeds, mortgages, liens), the Cook County Clerk’s land records search is the primary source, covering documents recorded since 1985. The Cook County Assessor’s portal provides ownership, assessed value, and exemption data searchable by PIN or address.

County Recorder Portals — Outside Cook County

For the remaining 101 counties, recorder of deeds and assessor records are maintained by individual county offices. Many counties use third-party platforms for online access. The NETRONLINE Illinois directory at publicrecords.netronline.com/state/IL links to recorder and assessor portals for all 102 counties. Major metro county portals include:

  • DuPage County Recorder — dupagerecorder.com
  • Lake County Recorder — co.lake.il.us/recorder
  • Will County Recorder — willcountyrecorder.com
  • Kane County Recorder — kanecorecorder.com
  • Winnebago County Recorder (Rockford) — winnebagorecorder.com

What Illinois Property Records Contain

  • Current and historical ownership (grantor/grantee names and dates)
  • Legal property description and Property Index Number (PIN)
  • Assessed value (equalized assessed value) and tax history
  • Sale history and deed transfer information
  • Mortgage recording and satisfaction history
  • Tax liens and judgment liens
  • Homeowner and senior exemption status (Cook County)

Illinois Business Records

Illinois Secretary of State — Business Entity Search

URL: ilsos.gov/corporatellc
Cost: Free for basic searches

The Illinois Secretary of State maintains the official registry of business entities formed or registered in Illinois — including corporations, LLCs, limited partnerships, and not-for-profit corporations. Search by entity name, file number, or registered agent. Results include entity status, formation date, registered agent, principal office address, and annual report history. Copies of filed documents (articles of incorporation, annual reports) can be ordered for a fee.

Illinois UCC Filings

URL: ilsos.gov/uccSearch
Cost: Free for searches

UCC financing statements filed with the Illinois Secretary of State are searchable by debtor name. These filings document secured transactions and liens on personal property used as collateral. UCC filings related to fixtures or real property may be filed at the county recorder level.

Illinois Transparency and Accountability Portal

URL: ledger.illinois.gov
Cost: Free

Illinois maintains a public expenditure portal showing state spending, contracts, and grants. Useful for researching state contractors and vendors without filing a FOIA request.


Illinois Vital Records

Illinois vital records — birth certificates, death certificates, marriage records, and dissolution of marriage records — are governed by the Illinois Vital Records Act (410 ILCS 535) and are explicitly not subject to FOIA. Birth and death records are maintained by the Illinois Department of Public Health (IDPH), Division of Vital Records in Springfield. Marriage and dissolution of marriage records are maintained at the county level — by the county clerk (marriage) or circuit court clerk (dissolution), not by the state.

How to Request Illinois Birth and Death Certificates

Online/Phone: VitalChek — vitalchek.com — expedited service available
Mail: IDPH Division of Vital Records, 925 E. Ridgely Avenue, Springfield, IL 62702-2737
Fee: $19 per certified copy (birth or death)
Phone: 217-782-6554
Processing time: Approximately 12 weeks by mail; 5–7 business days for urgent requests with proof of immediate need
Records begin: January 1916 for state-level records (earlier records held at county clerk level)

Birth Certificates

Illinois birth certificates are restricted records — not public records. Certified copies may only be issued to the registrant (if 18 or older), parents named on the certificate, legal guardians, legal representatives, and certain other authorized parties. Requests must include valid government-issued photo ID. The processing time at IDPH is notably long — approximately 12 weeks for standard mail requests — so plan accordingly for time-sensitive needs.

Death Certificates

Illinois death certificates are restricted records. Only individuals with a personal or property right interest — including family members, legal representatives, and parties with a demonstrated financial interest — are eligible to receive certified copies. The fee is $19 per copy. VitalChek provides expedited service for death certificates from 1916 to present.

Marriage Records

Marriage records in Illinois are maintained by the county clerk in the county where the marriage license was issued — not by the state IDPH. Contact the county clerk’s office directly for the county where the marriage occurred. Most counties charge a per-copy fee that varies. The IDPH Division of Vital Records can verify the existence of a marriage but does not issue certified copies of marriage certificates.

Dissolution of Marriage (Divorce) Records

Divorce records in Illinois are court records maintained by the circuit court clerk in the county where the dissolution was granted. Contact the circuit clerk of the relevant county for copies. The IDPH does not issue certified copies of dissolution records.


Illinois Inmate and Corrections Records

Illinois DOC Inmate Search

URL: idoc.illinois.gov (Inmate Search)
Cost: Free

The Illinois Department of Corrections maintains a public inmate search for individuals currently or previously incarcerated in Illinois state correctional facilities. Search by name or IDOC number. Results for current inmates include facility location, admission date, projected release date, and offense information. The database covers state prison populations — not county jails or federal facilities.

County Jail Rosters

Individuals held in county jails — including those recently arrested and awaiting trial — are managed by county sheriffs. Most major Illinois county sheriffs maintain online inmate search portals. The Cook County Sheriff’s inmate search is accessible at cookcountysheriff.org. For other counties, search the county sheriff’s website directly.

Federal Bureau of Prisons Inmate Locator

URL: bop.gov/inmateloc
Cost: Free

Individuals incarcerated in federal prisons — including those convicted of federal crimes in Illinois’s three federal districts — are searchable through the BOP Inmate Locator by name or federal register number.


Professional License Records

Illinois licenses more than 200 categories of professions through the Illinois Department of Financial and Professional Regulation (IDFPR), which is the primary professional licensing body in the state.

URL: idfpr.illinois.gov (License Lookup)
Cost: Free

IDFPR professions include: accountants, architects, cosmetologists, engineers, funeral directors, geologists, home inspectors, interior designers, nurses, physicians, pharmacists, physical therapists, real estate agents and brokers, social workers, and dozens more. The license lookup at idfpr.illinois.gov allows searches by name, license number, or profession type. Results include license status, issue date, expiration, and any disciplinary actions.

Additional professional licenses outside IDFPR include:

  • Attorneys — Illinois State Bar Association and ARDC (Attorney Registration and Disciplinary Commission) at iardc.org
  • Insurance agents and companies — Illinois Department of Insurance (insurance.illinois.gov)
  • Teachers and educators — Illinois State Board of Education (isbe.net)
  • Financial advisors and broker-dealers — Illinois Secretary of State Securities Division and FINRA BrokerCheck (brokercheck.finra.org)
  • Contractors — regulated at the municipal level in Illinois; Chicago requires licensing through the Chicago Department of Buildings (chicago.gov/buildings)

Charity and Nonprofit Records

Illinois charities soliciting donations from Illinois residents must register annually with the Illinois Attorney General’s Charitable Trust Bureau. Registration records — including charity name, officers, financial filings, and annual reports — are searchable through the AG’s Charitable Organization Registration search at illinoisattorneygeneral.gov/charities.

Federal tax-exempt organizations operating in Illinois file Form 990 with the IRS. These annual information returns — disclosing revenue, expenses, officer compensation, and program activities — are publicly available through:

  • IRS Tax Exempt Organization Search — apps.irs.gov/app/eos
  • ProPublica Nonprofit Explorer — projects.propublica.org/nonprofits
  • Candid (GuideStar) — candid.org

Illinois-incorporated nonprofit corporations are also registered with the Illinois Secretary of State and searchable through the business entity search at ilsos.gov/corporatellc.


How to Submit an Illinois FOIA Request

Step 1 — Identify the Public Body and FOIA Officer

Every public body subject to Illinois FOIA must designate a FOIA officer responsible for receiving and processing requests. For state agencies, FOIA officer contact information is typically listed on the agency’s website and in the Illinois Register. For local bodies — municipalities, school districts, counties — FOIA requests go directly to the clerk or FOIA officer for that entity. The Illinois Attorney General’s PAC website at illinoisattorneygeneral.gov/pac provides guidance and contact information for state agencies. Note that Illinois courts are not subject to FOIA — court records are governed by separate Supreme Court rules.

Step 2 — Submit the Request

FOIA requests must be submitted in writing — email, letter, fax, or in person. There is no official statewide request form, but the request must identify the records sought with reasonable specificity. Illinois does not require requesters to state their purpose, identify themselves, or demonstrate a need for the records. Any person may request records from any public body. Requests submitted to the public body’s website FOIA portal (where one exists) are often the fastest method.

Step 3 — Response Timeline

Illinois has one of the shortest mandatory response windows of any state:

  • Agencies must respond within five business days of receipt — either granting access, denying access, or invoking an extension
  • A single extension of up to five additional business days may be taken for specified reasons: unusual volume of requests, need for legal review, records stored at a remote facility, or consultation with another public body
  • A second extension requires a written explanation to the requester
  • Failure to respond within five business days constitutes a denial that can be immediately submitted to the PAC
  • Total maximum response time with one extension: ten business days

Step 4 — Fees

Illinois FOIA has one of the most requester-friendly fee structures of any state:

  • The first 50 pages of black and white paper copies must be provided free of charge
  • Pages beyond 50: actual cost of reproduction (typically $0.10–$0.15 per page)
  • Color copies: actual cost of reproduction
  • Electronic records: no charge for records already maintained electronically when delivered electronically
  • Certification: varies by agency
  • Fee waivers: fees must be waived when the requester is a news media organization or when disclosure is in the public interest and not primarily for commercial benefit — a broader waiver standard than most states

Step 5 — If Access Is Denied or Delayed

Illinois provides a layered enforcement structure:

  • Public Access Counselor (PAC) Request for Review — file a written Request for Review with the Attorney General’s PAC within 60 days of the denial. Submit by email to [email protected] or by mail to 500 South Second Street, Springfield, IL 62706, or call the PAC hotline at 877-299-3642. There is no fee. The PAC may issue a binding opinion (which functions as an administrative agency final order), resolve the dispute by mediation, or issue a determination letter. PAC binding opinions are subject to judicial review in Cook or Sangamon County.
  • Circuit Court action — any person denied access may file suit for injunctive or declaratory relief in the Circuit Court of the county where the requester resides or in Sangamon County. If successful, courts may award attorney fees and assess civil penalties of $2,500 to $5,000 per willful violation against the public body.
  • Note: if you file a circuit court action, the PAC takes no further action on any pending Request for Review.

Common Mistakes When Researching Illinois Public Records

Assuming Judici covers all 102 Illinois counties. Judici is excellent for the counties it covers but is not comprehensive statewide. A significant number of Illinois counties — particularly smaller downstate counties — do not participate. Before concluding a Judici search returned no results, verify whether that county is actually on the platform. For non-participating counties, contact the circuit clerk’s office directly or request records in person.

Using a UCIA conviction search and concluding someone has no criminal history. The UCIA search returns conviction records only — felonies and misdemeanors resulting in a guilty finding. It explicitly excludes arrests, pending charges, dismissed cases, and non-conviction records. A person may have multiple arrests and pending cases without any conviction, and none of that would appear in a UCIA search. For a more complete picture of someone’s involvement in the court system, supplement the UCIA search with a Judici or Cook County case search, which shows all case types regardless of outcome.

Searching Cook County using the same approach as other Illinois counties. Cook County operates parallel systems for almost every record type — its own circuit court case search (not Judici), its own merged Clerk/Recorder office for land records, its own three-way property system (Assessor/Clerk/Treasurer each separate), and its own rules around criminal records in-person access. Researchers who treat Cook County like any other Illinois county will consistently find dead ends. Cook County requires knowing which of its several portals to use for each specific record type.

Requesting marriage or divorce records from IDPH. The Illinois Department of Public Health issues birth and death certificates but does not issue certified copies of marriage or dissolution of marriage records. Marriage records are held by the county clerk in the county where the license was issued. Divorce records are held by the circuit court clerk where the dissolution was granted. Submitting a request to IDPH for a marriage or divorce certificate will result in a denial or no-record response even if the record exists.

Not submitting a PAC Request for Review within 60 days. The window to file a Request for Review with the Public Access Counselor is 60 days from the date of the final denial. This deadline is strictly enforced. Missing it means the PAC will not review that specific request, and the requester would need to file a new FOIA request and start the process over. Track denial dates carefully and put the 60-day deadline on your calendar immediately upon receiving a denial.

Expecting the 12-week IDPH vital records processing time to be negotiable. The Illinois Department of Public Health processes mail-in vital records requests in approximately 12 weeks under normal conditions — one of the longest processing times of any state in this guide series. For time-sensitive needs, use VitalChek for expedited service or submit directly to the county clerk (for births occurring more recently than 2010 at some counties). IDPH does offer expedited processing for proven urgent needs — include proof of immediate need (travel itinerary, medical appointment) and a prepaid overnight return envelope.


Frequently Asked Questions

Are Illinois public records open to anyone?

Yes. Illinois FOIA gives any person — regardless of residency, citizenship, or stated purpose — the right to request records from any public body subject to FOIA. Unlike Pennsylvania, there is no residency requirement. Unlike many states, requesters do not need to identify themselves or provide a reason for their request. The presumption is that all records are accessible unless the public body can demonstrate a specific statutory exemption applies.

Does Illinois have a FOIA law?

Yes — Illinois actually named its state open records law the Freedom of Information Act, using the same name as the federal statute. It is codified at 5 ILCS 140 and has no relation to the federal FOIA (which applies only to federal agencies). The current Illinois FOIA dates from 1984 and was substantially overhauled in 2010. The 2010 reforms created the Public Access Counselor, added mandatory training for FOIA officers, and strengthened the penalty structure. Illinois was notably the last state in the country to enact any freedom of information legislation.

Are Illinois criminal records public?

Only conviction records are public under Illinois law. The Uniform Conviction Information Act (20 ILCS 2635) mandates that all conviction information maintained by the Illinois State Police be publicly available through the CHIRP system for a fee of approximately $10–$16 per name search. Arrest records, non-conviction records, pending charges, and dismissed cases are explicitly not public under UCIA. For case activity beyond convictions — including pending cases and non-conviction dispositions — Judici (for most counties) and the Cook County case search portal provide free access to court dockets regardless of case outcome.

Where are Illinois property records searched?

It depends on the county. For Cook County (Chicago), use the Cook County Property Tax Portal at cookcountypropertyinfo.com as your starting point — it combines Assessor, Treasurer, Clerk, and Recorder data in one interface. For recorded documents specifically in Cook County, use the Cook County Clerk’s land records search at cookcountyclerkil.gov. For all other counties, start with the NETRONLINE Illinois directory at publicrecords.netronline.com/state/IL which links to each county’s recorder of deeds and assessor portals. Most suburban Chicago counties (DuPage, Lake, Will, Kane) have well-developed individual portals.

Are Illinois arrest records public?

Arrest records are not public records under the Uniform Conviction Information Act — only convictions are publicly accessible through the ISP CHIRP system. However, arrest information that led to court proceedings can be found through court case records on Judici or the Cook County case search, which show all case activity regardless of how the case resolved. Arrests that did not result in any court filing will not appear in either system. Some county sheriffs post recent booking information on their websites, but this is not uniform statewide.

Can an Illinois public body charge fees for FOIA records?

Yes, but with a notable requester-friendly provision: the first 50 pages of black and white paper copies must be provided free of charge. Beyond 50 pages, the body may charge the actual cost of reproduction — typically $0.10–$0.15 per page. Electronic records already maintained digitally must be provided electronically at no charge when delivered electronically. Fee waivers are available when the requester is a news media organization or when disclosure is in the public interest and not primarily for commercial purposes — a broader waiver standard than Pennsylvania or Florida. Fee disputes can be included in a PAC Request for Review.


Final Thoughts

Illinois FOIA, as reformed in 2010, is a genuinely strong public records framework — one of the few states with a dedicated enforcement body (the PAC) that can issue binding opinions with administrative law force, a free-first-50-pages provision that reduces the fee barrier for most individual requests, the shortest response deadline of any guide state (five business days with a maximum five-day extension), and meaningful civil penalty exposure for willful violations. The UCIA’s mandate that conviction records be public is also more accessible than New York (where official records are not public at all) or California (where there is no equivalent statewide conviction search tool).

The main practical challenges are Cook County’s complexity and the fragmented court record landscape. Cook County operates its own parallel universe for almost every record type, and researchers unfamiliar with the distinction between the Assessor, Clerk/Recorder, Treasurer, and Tax Portal systems will spend significant time navigating redundant searches. Outside Cook, the absence of a unified statewide court portal means researchers must either use Judici (for participating counties) or contact individual circuit court clerks directly — a meaningful gap compared to Pennsylvania’s comprehensive UJS portal.

For most research tasks: use Judici or the Cook County case search for court records, the ISP CHIRP system at $10–$16 for conviction history, the Cook County Property Tax Portal or NETRONLINE for property records, and the ILSOS business portal for corporate records. For FOIA requests to any state or local agency, the PAC at 877-299-3642 is both a resource for guidance and an enforcement body if needed.
