To file for divorce in Chicago, you file a Petition for Dissolution of Marriage with the Cook County Circuit Court’s Domestic Relations Division through the state’s mandatory eFileIL system, pay a filing fee of about $388, arrange formal service on your spouse, and appear at a short prove-up hearing where a judge signs the final judgment. At least one spouse must have lived in Illinois for 90 days before filing or before the judgment is entered.1Illinois General Assembly. Illinois Code 750 ILCS 5/401 – Dissolution of Marriage How long the case takes depends almost entirely on whether you and your spouse agree on the terms.
Residency and Grounds Before You File
Illinois requires 90 continuous days of state residency for at least one spouse before the court can enter a final judgment.1Illinois General Assembly. Illinois Code 750 ILCS 5/401 – Dissolution of Marriage There is no separate Cook County residency requirement. Without the 90 days, the court has no jurisdiction and the case cannot move forward.
Illinois is a pure no-fault state. The only ground for dissolution is irreconcilable differences. You do not plead adultery, cruelty, or abandonment, and none of them changes the outcome of your petition. If both spouses agree the marriage is over, the court accepts that. If one spouse disagrees, living separate and apart for at least six continuous months creates a conclusive presumption that irreconcilable differences exist.1Illinois General Assembly. Illinois Code 750 ILCS 5/401 – Dissolution of Marriage Separate and apart does not necessarily mean separate addresses; Illinois courts have recognized that spouses can live under the same roof while maintaining separate lives.
What Goes in the Petition
The case opens with a Petition for Dissolution of Marriage. Illinois statute sets the minimum contents:2Illinois General Assembly. Illinois Code 750 ILCS 5/403 – Pleadings, Commencement, Abolition of Existing Defenses, Procedure
- Each spouse’s age, occupation, current address, and length of Illinois residency
- The date and place the marriage was registered
- Names, ages, and addresses of all living children of the marriage, and whether either spouse is pregnant
- Whether a dissolution petition is already pending in another county or state
- Any agreements about child support, parenting responsibilities, and spousal maintenance
- What you are asking the court to do
You will file the petition together with a Summons and the Domestic Relations Cover Sheet. Both are standard Cook County forms and are available through the Clerk of the Circuit Court’s website.3Circuit Court of Cook County. Domestic Relations Division Before you file, pull together a full picture of your financial life: bank statements, real estate records, retirement account balances, vehicle titles, and outstanding debts. You will need those numbers for the petition and again for the property division that follows.
Filing Through eFileIL
All civil filings in Cook County must be submitted electronically. The Illinois Supreme Court mandated e-filing for civil cases in Cook County effective July 1, 2018, and paper filing is no longer an option for most litigants.4Clerk of the Circuit Court of Cook County. eFile
Create an account on the statewide Odyssey eFileIL platform, select Cook County as your filing location, and upload your completed forms as PDFs.5Office of the Illinois Courts. How to e-File The system prompts you to pay the filing fee by credit card or electronic check. Once submitted, you receive an electronic timestamp. The clerk reviews the documents for technical compliance and then assigns a case number and a judicial calendar.
Filing Fees and Fee Waivers
The filing fee in Cook County is approximately $388 for the petitioner. The respondent pays a separate, smaller fee when filing an appearance. Fees change from time to time, so check the clerk’s current schedule before you file.
If you cannot afford the fee, submit an Application for Waiver of Court Fees with your petition. This standardized form is approved by the Illinois Supreme Court and available on the Illinois Courts website; it asks for household size, income, monthly expenses, and assets.6Illinois Courts. Approved Statewide Forms – Fee Waiver for Civil Cases A judge reviews the application and grants a full or partial waiver under Illinois Supreme Court Rule 298 and 735 ILCS 5/5-105.7Illinois Courts. Illinois Supreme Court Rule 298 – Application for Waiver of Court Fees, Costs, and Charges There is no fee for filing the waiver application itself.
Serving Your Spouse
Once the clerk accepts your filing and issues a case number, you have to formally deliver the Summons and Petition to your spouse. You cannot hand them the papers yourself. The most common route in Cook County is the Sheriff’s Office, which charges $60 per service for e-filed cases, plus a $10 mileage fee unless your spouse appears voluntarily at the sheriff’s office.8Cook County Sheriff’s Office. Serving Process (Summons) You can also hire a private process server, which is common when the sheriff has trouble locating your spouse. In limited circumstances a court may allow service by publication when a spouse cannot be found after diligent effort.
Whoever serves the papers must then complete and file a Proof of Service with the clerk. Without it the court has no evidence your spouse received notice, and the case cannot move forward.
After Service: Response, Uncontested, or Contested
Your spouse has 30 days from the date of service to file an Entry of Appearance and respond to the petition. What happens next depends on whether they respond and whether the two of you agree on the terms.
If your spouse files an appearance and you agree on everything — division of property, parenting, support, maintenance — the case is uncontested and moves directly toward a prove-up hearing. If your spouse disagrees on any material issue, the case is contested and follows a longer path through discovery, possible mediation, and potentially trial. If your spouse never responds within the 30 days, you can generally proceed toward a default judgment.
The Prove-Up Hearing
The prove-up is the short court appearance where an uncontested divorce is finalized. The petitioner takes the stand and gives brief testimony confirming the facts in the petition: length of Illinois residency, the date of marriage, that the marriage has broken down, and that both spouses agree to the proposed terms. Testimony is mostly yes-or-no questions and takes five to ten minutes.
The judge reviews the proposed Judgment for Dissolution of Marriage, along with any settlement agreement and parenting plan, to confirm the terms comply with Illinois law and are not unconscionable. If everything is in order, the judge signs the judgment on the spot and the marriage is legally dissolved that same day. If the judge sees a problem with fairness or completeness, you may be asked to revise the paperwork. Cook County often schedules multiple prove-ups in the same block, so plan on one to two hours in the courthouse even though your time in front of the judge is brief.
Issues Your Judgment Should Address
A dissolution case does more than end the marriage; the judgment resolves property, debts, and related matters. A few points come up often enough that they belong on your checklist before the prove-up.
Restoring a Former Name
If you changed your name at marriage and want to go back to your former or maiden name, the divorce judgment can authorize that change. Illinois law provides that the judgment should include a provision allowing you to resume your prior name at any time unless you specifically ask the court not to include it.9Illinois General Assembly. Illinois Code 750 ILCS 5/413 – Judgment of Dissolution of Marriage, Declaration of Invalidity of Marriage With that provision in place, no separate name-change petition or publication is needed. You use the certified judgment as proof when updating your Social Security card, driver’s license, passport, and other identification.
Retirement Accounts
Retirement accounts accumulated during the marriage are marital property. Employer-sponsored plans like 401(k)s and pensions require a Qualified Domestic Relations Order (QDRO), a separate court order that directs the plan administrator to pay a portion of one spouse’s retirement benefits to the other. A QDRO must identify both spouses by name and address, name the specific plan, and specify a dollar amount or percentage.10U.S. Department of Labor. QDROs Chapter 1 – Qualified Domestic Relations Orders: An Overview A private agreement between spouses is not enough; the order must be issued or approved by a court.
With a proper QDRO, funds can transfer tax-free if rolled directly into the receiving spouse’s retirement account. Without one, a distribution from an employer plan to a non-participant spouse is treated as taxable income to the employee spouse and may trigger a 10% early withdrawal penalty.11Office of the Law Revision Counsel. 26 USC 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts IRAs work differently. QDROs do not apply to them; federal tax law allows a direct account-to-account transfer between spouses or former spouses under a divorce decree as a “transfer incident to divorce,” without tax or penalty.12Office of the Law Revision Counsel. 26 USC 408 – Individual Retirement Accounts Cash out the IRA yourself and hand your ex the money, and you will owe taxes and potentially penalties.
Joint Debts
The judgment can assign specific debts to one spouse, but that assignment only binds the two of you. It does not change your contract with the lender. If you co-signed a mortgage, car loan, or credit card, the creditor can still pursue either of you for the full balance no matter what the decree says. If your ex stops paying on a joint account the judgment assigned to them, the missed payments hit your credit and the creditor can come after you.
The practical fix is to eliminate joint accounts before or during the divorce: refinance the mortgage into one spouse’s name, close joint credit cards, and convert joint auto loans to individual ones. Where refinancing isn’t possible, the settlement should include protections such as a deadline for the responsible spouse to refinance and a right to return to court for enforcement if payments are missed.
