Cook County Divorce Timeline

A step-by-step look at how a divorce moves through the Domestic Relations Division of the Circuit Court of Cook County.

What to Expect in Your Domestic Relations Case

If you just filed or were just served, the question we hear most often is the same: "What happens next?"

Under the Illinois Marriage and Dissolution of Marriage Act, every divorce follows the same basic progression. A heavily contested case moves differently than a negotiated one, but knowing the structure of a Cook County case lets you make decisions with a clear picture of what is ahead.

Below is how a typical case unfolds in the Domestic Relations Division of the Circuit Court of Cook County. Most Chicago cases are heard at the Daley Center. Cases from the suburbs are generally assigned to the district courthouse for that area (Skokie, Rolling Meadows, Maywood, Bridgeview, or Markham). The time ranges are estimates. Every case moves at its own pace, and the biggest factor is how far apart the two of you are on the issues.

Phase 1: Filing and Service (Weeks 1–4)

1. Filing the Petition for Dissolution of Marriage

Your case begins when your attorney e-files a Petition for Dissolution of Marriage with the Clerk of the Circuit Court of Cook County. The petition lays out the basic facts of the marriage, identifies any children, and states what you are asking the court to do about parenting, support, maintenance, and property.

2. Service of Process

Your spouse must be formally served with the petition and summons. In Cook County, that is done by the Cook County Sheriff, a licensed private detective, or a special process server appointed by the court. If your spouse already has a lawyer, the lawyer will often file an appearance and accept service, which avoids a deputy showing up at the door.

3. The Response

Once served, your spouse has 30 days to file an appearance and a response. If nothing is filed, your attorney can ask the court to enter a default. In practice, most cases are contested to some degree and both sides appear.

Phase 2: Temporary Relief and Financial Disclosure (Months 1–4)

4. Temporary Relief

A divorce can take months, but bills and parenting schedules cannot wait. Either party can ask the court for temporary orders while the case is pending, including:

Temporary parenting time and child support
Temporary maintenance
Exclusive possession of the marital home
Interim attorney's fees so both sides can afford counsel

5. Financial Affidavit and Disclosure

Illinois requires both parties to complete and exchange the statewide Financial Affidavit, which lays out income, expenses, assets, and debts under oath. It has to be backed up with documents: recent tax returns, pay stubs, bank and retirement statements, and business records if either spouse owns a business. This exchange is what makes real settlement negotiations possible.

6. Parenting Education and Mediation

If you have children, Cook County requires both parents to complete a parenting education program early in the case. If parenting time or decision-making is disputed, the court will generally send the parties to mediation before it hears those issues, and in some cases will appoint a guardian ad litem or child representative to investigate and make recommendations.

Phase 3: Discovery and Valuation (Months 3–9)

7. Interrogatories and Requests for Production

When there are complex assets, questions about income, or contested parenting issues, the attorneys use formal discovery: written interrogatories answered under oath, requests for documents, and subpoenas to banks, employers, or other third parties. The point is to nail down the full picture of the marital estate before anyone negotiates over it.

8. Depositions and Appraisals

In higher-asset or heavily contested cases, depositions are taken, meaning each side's attorney questions the other spouse (and sometimes other witnesses) under oath in front of a court reporter. This is also when businesses, professional practices, real estate, and retirement accounts are valued, often with the help of an appraiser or forensic accountant.

Phase 4: Case Management and Settlement (Months 6–12)

9. Case Management and Status Dates

Cook County judges keep their cases moving. The court sets regular status and case management dates to make sure discovery is on track, temporary issues are handled, and the case is heading toward resolution. Most of these are short, and many are handled remotely.

10. The Pretrial Conference

If the parties are still apart on key issues, the attorneys will request a pretrial conference with the judge. Each side submits a pretrial memorandum laying out its position, and the judge gives an informal read on how they would likely rule. That recommendation is not binding, but it resolves a large share of cases because both sides now know what a trial is likely to produce.

Phase 5: Prove-Up or Trial (Months 9–18+)

11. Prove-Up (Settled Cases)

When the case settles, your attorney drafts a Marital Settlement Agreement and, if there are children, an Allocation Judgment and Parenting Plan. Once both sides sign, a short uncontested hearing called a prove-up is scheduled. The judge confirms the agreements are fair and voluntary and enters the Judgment for Dissolution of Marriage. The prove-up itself usually takes minutes.

12. Trial (Contested Cases)

If settlement is impossible, the case goes to trial in front of the judge. There are no jury trials in Illinois divorce cases. Both sides present evidence and witnesses, cross-examine, and make closing arguments. The judge then takes the case under advisement and issues a written Judgment for Dissolution of Marriage that decides every open issue.
