Cook County public records are routed by record type, with property matters split among county tax and assessment offices while court and custody questions use separate court and sheriff resources. Use the categories below to choose the best public-records page for the kind of record need you have.
- Property Search The Cook County Assessor's Office is the better fit for address, PIN, neighborhood, and assessment-related property details, while recorded land records are handled through the Cook County Clerk.
- Property Tax The Cook County Property Tax Portal is the starting point for tax information by address or PIN, with related assessment, payment, exemption, appeal, and redemption questions handled by different county offices.
- Court Records The Clerk of the Circuit Court of Cook County Online Case Search fits general case-status needs, while official court records and older files may require courthouse, repository, or Archives Department records.
- Inmate Search The Individual in Custody Locator is the official starting point for finding a person currently listed in custody and following up on visitation, bond, mail, property, or trust account questions.
- Marriage Records The Cook County Clerk’s Bureau of Vital Records handles certified marriage certificates for marriages that occur in Chicago and suburban Cook County after the completed license is filed.
