Illinois does not require both spouses to agree
Illinois is a no-fault state. Under 750 ILCS 5/401, the court enters a judgment of dissolution when irreconcilable differences have caused the irretrievable breakdown of the marriage and reconciliation has failed or would be impracticable. One spouse must have lived in Illinois, or been stationed here in the military, for 90 days before the case began or before the finding.
If the spouses have lived separate and apart for a continuous period of at least 6 months immediately before the judgment, the law treats irreconcilable differences as proven. That presumption cannot be rebutted. A spouse can disagree about money or the children, but cannot keep the marriage going just by refusing to cooperate.

Which papers a spouse might refuse to sign
"Divorce papers" can mean several different documents, and refusing each one has a different effect:
- A waiver of service. Illinois lets a petitioner ask a spouse to waive formal service under 735 ILCS 5/2-213. A spouse may refuse. Then you serve a summons the usual way.
- An appearance and response. If your spouse never files them, the case can proceed by default.
- A marital settlement agreement or parenting plan. If your spouse will not sign an agreement, the case is contested and the judge decides the disputed issues.
Start by filing a petition for dissolution of marriage. Our guide on how to file for divorce in Cook County walks through the filing itself.
Serving a spouse who will not cooperate
Service gives the court authority over your spouse and starts the response clock. Under Supreme Court Rule 101(d), a summons requires the respondent to file an appearance or answer within 30 days after service, not counting the day of service.
Sheriff and special process server
Under 735 ILCS 5/2-202, the sheriff can serve process, and a licensed private detective or registered employee of a licensed agency can serve in any county without special appointment. The court can also, on motion, appoint another adult who is not a party. Under 735 ILCS 5/2-203, service is made by handing the summons to your spouse, or by leaving it at your spouse's usual home with a family member or resident who is at least 13 and then mailing a copy there. You cannot serve your spouse yourself.
Service by publication
If your spouse has left Illinois, cannot be found after diligent inquiry, or is hiding to avoid service, 735 ILCS 5/2-206 allows notice by publication. You file an affidavit describing the search, the clerk publishes a notice in a newspaper in the county, and the clerk mails a copy to any known address within 10 days. Under 2-207, the notice runs once a week for 3 successive weeks, and no default can be taken until at least 30 days after the first publication.
Judges expect a real search before publication: last known addresses, relatives, employers, social media, and attempts by the sheriff or a process server. See our guide on how to serve divorce papers in Illinois.
Default: what happens if your spouse does not respond
Under 735 ILCS 5/2-1301(d), a judgment by default may be entered for want of an appearance or for failure to plead, and the court may still require proof of the allegations. People often call the result a default divorce. In the Cook County Domestic Relations Division, the petitioner files a Certification for Default Hearing; an order of default is entered and the case is assigned to a judge for hearing under Cook County Circuit Court Rule 13.5.
A few rules change when a spouse defaults:
- If the respondent never files an appearance, Section 602.10(a) says no parenting plan is required unless the court orders one. The judge still must make provision for parenting before judgment, so a proposed plan helps.
- Under Supreme Court Rule 924, only the petitioning parent must complete the parenting education program in a default.
- Cook County keeps a military calendar so that no default is taken against an active service member because of an absence caused by military service.
Your spouse can still file an appearance before the default is entered. If that happens, the case goes forward with both spouses taking part.
The prove-up hearing
A default does not mean you automatically get everything you asked for. At the prove-up, you testify under oath about residency, the breakdown of the marriage and the relief you want, and the judge decides whether the evidence supports it. Section 401(b) bars a judgment until the court has considered, approved, reserved or made provision for parenting, child support, maintenance and property. In Cook County, all testimony in default cases is recorded, transcribed and filed with the clerk.
Plan to bring:
- The proof of service or the publication certificate.
- A proposed Judgment for Dissolution of Marriage.
- Your financial affidavit and income records.
- A proposed parenting plan and support order if you have children.
- Records of property, debts, accounts and the home.
Timelines vary with service, publication and the court's calendar. In Cook County, the case is also called for a status report no later than 6 months after filing, and a petitioner who misses it risks dismissal for want of prosecution.
Can a default be vacated later?
Yes, within limits. Under Section 2-1301(e), the court may set aside a default before final judgment, and on a motion filed within 30 days after a final judgment may set it aside on reasonable terms. After 30 days, a party generally must file a petition under 735 ILCS 5/2-1401 within 2 years, supported by an affidavit. A judgment entered without valid service can be attacked as void, and a spouse served only by publication who never received the complaint or the mailed notice may have extra time under Section 2-1301(g) to ask to be heard.
That is why careful service matters. Read more in our guide to motions to vacate in Illinois family cases.
What your spouse can still do
A spouse who refuses to sign is not shut out of the case. Before a default is entered, your spouse can still file an appearance and a response after the 30 days have run, sometimes with leave of court. The case then goes forward with both spouses taking part. Your spouse can also file a counter-petition, ask for temporary support or parenting time, challenge how service was made, or ask for more time.
If your spouse participates and you still disagree, the divorce is contested. That usually means financial disclosure and discovery, mediation of any parenting dispute in Cook County, and either a negotiated settlement or a trial. If you have lived apart for at least 6 continuous months before judgment, the separation presumption applies, so the question becomes how the issues are resolved, not whether the marriage ends. If a default judgment is entered, your spouse's remaining options are the motions and petitions described above.
Common mistakes to avoid
- Guessing at an address. Bad service can undo the judgment later.
- Using a friend as a process server without a court order. Only authorized servers count.
- Publishing too early. Courts expect a documented, diligent search first.
- Arriving at the prove-up without proof. The judge still needs evidence for support, property and parenting terms.
- Letting the case sit. Missing a status date can lead to dismissal.
