What Mount Prospect Divorce Files Contain
A Cook County divorce file for a Mount Prospect case is the complete official record of the proceeding. The petition for dissolution of marriage starts the file, identifying both parties, any children of the marriage, and the relief requested. The respondent's answer follows. In contested cases, counterpetitions and motions add to the file throughout the litigation.
Financial affidavits are a key part of any divorce file. Both parties disclose income, assets, and liabilities. The court uses these to decide property division, maintenance, and child support. All signed orders from the judge go into the file. The case ends with the judgment of dissolution and, if children are involved, a parenting plan establishing custody and visitation.
Illinois divorce law is set out in 750 ILCS 5. This law requires a finding of irreconcilable differences and a 90-day Illinois residency period for at least one spouse before a dissolution can be filed.
The IDPH dissolution of marriage records page explains statewide verification services for Illinois divorces.
IDPH verifications cover Illinois divorces from 1962 forward and can help confirm whether a Cook County case is in the statewide index.
IDPH Statewide Divorce Verification
The Illinois Department of Public Health maintains a statewide divorce index from 1962 to the present. For a $5 fee, the IDPH will verify basic facts about an Illinois divorce: names, date, and county. This is useful when you aren't sure which county handled the case or when a quick summary is enough.
Send requests to: Division of Vital Records, 925 E. Ridgely Ave., Springfield, IL 62702. Phone: (217) 782-6553. Processing takes an average of four to six weeks for mail requests. Always include a copy of a valid government-issued photo ID.
An IDPH verification is not a certified copy of the decree. If you need the actual judgment for legal or financial purposes, you must get a certified copy from the Cook County Circuit Court Clerk.
