Cook County Divorce FAQs

What is the residency requirement to file for divorce in Illinois?

At least one spouse must have lived in Illinois for 3 months before filing for divorce. This requirement is set by state law and applies throughout the state, including Cook County.

Is there a waiting period for divorce in Illinois?

Illinois does not impose a mandatory waiting period before a divorce can be finalized. Actual timelines in Cook County still depend on the court's caseload and how the case proceeds.

How much does it cost to file for divorce in Cook County?

The court filing fee for a divorce in Illinois is $250–$400. Fee waivers may be available for filers who cannot afford the fee — ask the court clerk about the waiver process. Beyond the filing fee, the median total cost of an uncontested divorce in Illinois is about $3,000 (2023 data).

Does Illinois allow no-fault divorce?

Yes. Illinois is a pure no-fault jurisdiction — neither spouse needs to prove wrongdoing to obtain a divorce.

How is property divided in a Illinois divorce?

Illinois uses equitable distribution: marital property is divided based on what the court finds fair in the circumstances of each case, which is not always an equal split.
