The final divorce hearing in Illinois is called a prove-up hearing, and for an uncontested case it lasts 5 to 20 minutes. You testify under oath that irreconcilable differences broke the marriage and that your settlement is fair. Under 750 ILCS 5/413, the judge enters the Judgment for Dissolution within 60 days of the closing of proofs.
This guide explains exactly what happens at the final divorce hearing in Illinois: who must attend, the questions the judge asks, the documents you bring, county-specific procedures including affidavit-only prove-ups, and how the Judgment for Dissolution of Marriage makes your divorce final. Illinois eliminated fault grounds in 2016, so every dissolution now proceeds on irreconcilable differences under 750 ILCS 5/401.

What Is a Prove-Up Hearing in Illinois?
A prove-up hearing is the final court appearance in an uncontested Illinois divorce, and it typically lasts 5 to 10 minutes. You "prove up" your case by testifying under oath that you meet the residency and grounds requirements and that your Marital Settlement Agreement is fair and voluntary. This hearing transforms your written agreement into a binding court order under 750 ILCS 5/502.
The final divorce hearing in Illinois exists because the state requires a judge to confirm two things before dissolving a marriage: that irreconcilable differences caused an irretrievable breakdown, and that any settlement is not unconscionable. The judge is not there to second-guess your decisions. Instead, the judge verifies that both spouses understand the agreement, signed it voluntarily, and that its terms comply with Illinois law. Once the judge is satisfied, the court signs the Judgment for Dissolution of Marriage, and the parties are officially divorced. For the roughly 95 percent of Illinois divorces that settle before trial, the prove-up is the only substantive court appearance either spouse attends.
Who Must Attend the Final Divorce Hearing in Illinois?
The petitioner must always attend the prove-up hearing in Illinois, along with their attorney if represented. The respondent may appear but is not legally required to be present for the court to finalize the divorce. If the respondent filed an Appearance and signed the Marital Settlement Agreement, their physical presence at the final hearing is optional in most counties.
Attendance rules at the final divorce hearing in Illinois depend on whether the case is agreed or proceeding by default. In a fully agreed uncontested divorce, the petitioner testifies to establish the record, and the signed agreement controls even if the respondent never appears. When the respondent refuses to participate, the case can proceed as a default prove-up under 750 ILCS 5/405, but the petitioner must satisfy the judge that all proper means were taken to notify the respondent of the suit. In cases involving minor children, both parents must have completed the mandatory parenting education course, and the judge will confirm that certificates of completion are on file before entering the Allocation Judgment governing parenting time and decision-making responsibility.
What Questions Does the Judge Ask at an Illinois Prove-Up?
At an uncontested divorce hearing, the judge asks a short series of yes-or-no questions under oath that summarize your Petition and Marital Settlement Agreement, typically 8 to 12 questions taking under 10 minutes. Every material line of your petition becomes a question, covering residency, grounds, children, and whether you understand and voluntarily signed the agreement.
Expect the following categories of questions at the final divorce hearing in Illinois. First, jurisdiction and residency: the judge confirms you or your spouse lived in Illinois for at least 90 days. Second, grounds: "Do irreconcilable differences exist that caused the irretrievable breakdown of the marriage, and have efforts at reconciliation failed?" Third, children: "Do you have any minor children of this marriage? Is the wife currently pregnant?" Fourth, the agreement: "Have you read, understood, and voluntarily signed the Marital Settlement Agreement without coercion, and do you believe it is fair and reasonable?" Your attorney briefs you on these questions before the hearing, so there are no surprises. Because Illinois is a no-fault state, only one spouse needs to believe the marriage is irretrievably broken for the court to grant the divorce.
What Documents Do You Need for the Final Hearing?
Every uncontested prove-up in Illinois requires a written Marital Settlement Agreement dividing all assets and debts, signed by both spouses. Cases with minor children also require an Allocation Judgment (parenting plan) and proof both parents completed the mandatory parenting class. You must also file the statewide financial affidavit under 750 ILCS 5/501.
The core documents at the final divorce hearing in Illinois form a package the judge reviews before entering judgment. The Petition for Dissolution of Marriage frames the requested relief. The Marital Settlement Agreement, required to be in writing under 750 ILCS 5/502, governs property division, allocation of debts, and spousal maintenance. The proposed Judgment for Dissolution of Marriage is the order the judge signs. For parents, the Allocation Judgment sets parenting time and decision-making responsibility, and each parent must file a certificate of attendance for the court-ordered parenting course. The statewide financial affidavit, supported by documentary evidence such as pay stubs and tax returns, allows the court to detect any disparity between sworn income and supporting records. Courts must assess penalties for intentionally inaccurate or misleading financial affidavits under 750 ILCS 5/501(a).
Illinois Prove-Up Timeline: Contested vs. Uncontested
An uncontested Illinois divorce reaches its prove-up hearing in roughly 2 to 4 months after filing, while a contested divorce that goes to trial can take 12 to 30 months. The prove-up itself lasts 5 to 20 minutes; a contested trial can span multiple days. Judgment is entered within 60 days of the closing of proofs under 750 ILCS 5/413.
The table below compares the two paths to a final judgment in Illinois. The single largest variable is whether the spouses agree on all terms before the final hearing.
| Factor | Uncontested (Prove-Up) | Contested (Trial) |
|---|---|---|
| Time from filing to final hearing | 2–4 months | 12–30 months |
| Length of final hearing | 5–20 minutes | Multiple hours to several days |
| Testimony required | Petitioner (brief, yes/no) | Both parties, witnesses, experts |
| Cost range (attorney fees) | $1,500–$5,000 | $15,000–$50,000+ |
| Judgment entered after | Same day or within days | Within 60 days of closing proofs (up to 90 with good cause) |
| Respondent attendance | Optional if agreement signed | Required |
The faster path is the Joint Simplified Dissolution under 750 ILCS 5/452, available to couples with no minor children, married under 8 years, combined marital property under $50,000, and combined gross annual income under $60,000. In Cook County, a Joint Simplified Dissolution can be heard the same day it is filed.
What Happens After the Judge Signs the Judgment?
Once the judge signs the Judgment for Dissolution of Marriage at the prove-up, your divorce is final and effective immediately under 750 ILCS 5/413. The judgment is final when entered, subject to a 30-day window to appeal. The clerk forwards a dissolution certificate to the Illinois Department of Public Health within 45 days after the close of the month in which judgment is entered.
After the final divorce hearing in Illinois, several practical steps follow. The signed judgment becomes an enforceable court order, meaning any Qualified Domestic Relations Order (QDRO) for dividing retirement accounts must be prepared and entered, deeds transferring real estate must be recorded, and beneficiary designations on insurance and retirement plans should be updated. If either spouse changed their name, the judgment authorizes that change and can be used to update Social Security and driver's license records. The judgment is final when entered under 750 ILCS 5/413, and either party may remarry once the appeal period passes. If the terms of the incorporated agreement conflict with anything said during prove-up testimony, the written agreement controls, so accuracy in the document matters far more than the oral answers given at the hearing.
County Variations: Zoom and Affidavit-Only Prove-Ups
Many Illinois counties now conduct uncontested prove-up hearings remotely by Zoom, and several allow divorce by affidavit with no court appearance at all. DuPage, Kane, and Lake Counties permit affidavit-based prove-ups where spouses submit sworn statements instead of appearing. McHenry County allows affidavit prove-ups by permission. Cook County commonly conducts remote video prove-ups.
Procedures at the final divorce hearing in Illinois vary by judicial circuit because prove-up mechanics are set by local court rules, not by the statute itself. Since the pandemic, remote video prove-ups over Zoom have become the default in many courtrooms for uncontested cases, sparing spouses a trip to the courthouse. In DuPage County, Kane County, and Lake County, an uncontested divorce can be finalized entirely on affidavits, meaning neither spouse testifies live before a judge. McHenry County permits affidavit prove-ups when the court grants leave. Cook County's Domestic Relations Division routinely schedules remote prove-ups but may require live testimony in cases involving minor children or contested issues that were resolved shortly before the hearing. Because these rules change and differ between the state's 25 judicial circuits, confirm your county's current prove-up format with the Circuit Clerk before your hearing date.
How to Prepare for Your Illinois Prove-Up Hearing
Prepare for your Illinois prove-up by reviewing every term of your Marital Settlement Agreement, confirming your 90-day residency, and, if you have children, filing your parenting class certificate. Your attorney will review the yes-or-no questions with you beforehand, so the 5-to-20-minute hearing holds no surprises. Raise any concerns about the agreement before the hearing, never during testimony.
Effective preparation for the final divorce hearing in Illinois centers on familiarity with your own documents. Read the Marital Settlement Agreement in full so you can honestly affirm it is fair and that you signed voluntarily. Verify the residency facts you will testify to, since the court must have jurisdiction under 750 ILCS 5/401. Parents should confirm both certificates of parenting-class completion are filed and that the Allocation Judgment reflects the agreed parenting schedule. On the day of the hearing, dress respectfully, appear sober and clear-headed, and answer only the question asked. If you realize before the hearing that you no longer agree with a term, tell your attorney immediately; a judge who finds an agreement unconscionable can reject it and send you back to renegotiate, delaying the divorce. The goal at prove-up is a clean, accurate record that lets the judge sign the Judgment for Dissolution the same day.
