Guidance checked
- Who can request
- Any person may request existing public records. A public body is not required to answer questions, explain its decisions, or create a record that does not already exist.
- How to file
- Make the request in writing to the public body's FOIA officer and describe the records as specifically as possible. No single statewide form is required for an ordinary request.
- Initial response
- A public body generally must respond within five business days. It may extend once for an additional five business days for specific statutory reasons, but must notify you in writing of the reason and new due date.
- Possible fees
- The first 50 pages of standard black-and-white paper copies are free; additional standard pages may be charged at 15 cents each. Search and review fees generally do not apply to non-commercial requests.
- If access is denied
- A requester can submit a Request for Review to the Attorney General's Public Access Counselor, generally within 60 calendar days after the denial, or pursue relief in circuit court.
What Illinois's Freedom of Information Act actually does
It gives you a right to request records held by government bodies in Illinois, and it obliges those bodies to respond. That is a right of access to what an agency holds - not a search engine, and not a database of people.
Two consequences people are regularly surprised by. First, a records law says nothing about information held by private companies: employers, landlords, banks and social platforms are outside it entirely. Second, the right is to records, not to answers - you generally have to identify what you want well enough for someone to find it, and “everything you have about this person” is usually not a valid request.
Every state also exempts categories of record from disclosure, and those exemptions are where most of the complexity lives. Assume the existence of a record is a separate question from whether it is releasable.
A request you can adapt
Start with the official guidance above when it requires a form or a particular submission route. Otherwise, this structure helps an agency identify existing records without turning your request into an open-ended question.
This is a drafting aid, not an official state form. Save the request, proof of delivery, every cost estimate, and every response in one place.
Where the records actually live
There is no single office. Records are held by whichever body created them, which is why “how do I get X in Illinois” has a different answer for each X:
- Court records - held by the court that heard the case. Some states run a statewide portal; others are county by county, and a few are both.
- Property records - usually the county recorder, assessor, or registry of deeds, and often searchable online.
- Vital records - birth, death, marriage, divorce. Held by a state vital-records office, a county clerk, or split between them, and typically the most restricted category.
- Criminal history - held by a state agency, with access rules that differ sharply from state to state.
- Business filings- the state’s corporate registry, generally the most open of the categories.
We’ve deliberately not named the specific office for each of these. They differ by record type and by county, they change, and a confident wrong pointer costs you an afternoon. Search for the record type plus Illinois on a .gov domain, and start from the office that would have created the record.
The line that matters more than the statute
Records being public does not make every use of them lawful. In the United States the Fair Credit Reporting Act governs information used to decide someone’s eligibility for employment, credit, housing, insurance, or tenancy.
For those decisions you need a consumer reporting agency operating under the FCRA, with the subject’s consent and their right to see and dispute what was reported. A public-records search - ours included - meets none of those requirements, and DeepSearch states plainly that it is not a consumer reporting agency. That is a real constraint, not boilerplate.
Reading a public record to satisfy yourself that someone is who they say they are is ordinary. Using it to monitor or pressure a person who doesn’t want to hear from you is not, and the information having been public is not a defence.
This is general information, not legal advice. Records laws are amended and interpreted by courts; if a decision matters, take proper advice.
