Deerfield, Illinois Public Records

Illinois operates a unified court system, so the Circuit Court is the trial court of general jurisdiction—there is no separate municipal court for Deerfield. Cases are divided among divisions: Criminal, Civil, Domestic Relations, Probate, Traffic, and Juvenile. The Lake County Circuit Clerk's Office maintains all court records and case files. Illinois courts participate in an online case search system; the statewide case search portal is available through individual circuit court websites, and Lake County provides online docket access at https://www.19thcircuitcourt.state.il.us for searching civil, criminal, traffic, and domestic relations cases by party name or case number. Many case documents can be viewed online, though some records (especially involving minors or sealed cases) remain confidential. The Circuit Clerk charges fees for certified copies of documents: typically $8 for the first page and $2 for each additional page of the same document, plus a $6 certification fee. Regular photocopies are $1 per page. Remote access to electronic documents may require establishing an account. Court records more than 20 years old may require special retrieval from archives. Traffic tickets issued in Deerfield are handled by the Lake County Traffic Division at the Waukegan courthouse, where defendants can appear, pay fines, or contest citations.

The Assessor's website provides a free online Property Tax Portal where residents can search by address, property index number (PIN), or owner name to view current and historical assessed values, property characteristics (square footage, age, lot size), tax exemptions, recent sales data, and assessment history.
