In the early 1800's, the legislature, the circuit courts, and city courts granted divorces. Illinois divorce records may indicate the date and place the marriage was dissolved. Circuit or city courts have handled most divorce proceedings. The Superior Court of Cook County in Chicago also has jurisdiction over divorces.
The actual records before 1962 are available in the county where the divorce occurred.
