Back to all statesIllinois public records are governed by the Illinois Freedom of Information Act, which gives residents and the public the right to access government documents and records. From property ownership and court records to business filings and vital statistics, Illinois maintains extensive public databases across its 102 counties. Illinois requires agencies to respond to FOIA requests within five business days, and Cook County alone publishes one of the largest online property and court record systems in the country. Whether you're conducting a background check, researching property history, or verifying business information, the resources below provide direct access to official Illinois public records.
Most Illinois public records can be accessed online through state agency portals like the Illinois State Archives and the Illinois Department of Public Health Division of Vital Records, or through individual county clerk websites. For records not published online, agencies accept written requests under the Illinois Freedom of Information Act — usually by mail or email — and must respond within the statutory deadline. Certified copies of vital records and court documents typically require a small fee and proof of identity.
