An uncontested divorce is not a separate legal procedure in Illinois so much as a description of how a case is resolved: both spouses agree on every issue before the petition is filed, or shortly after. It is faster and cheaper than a litigated divorce, but "agreed" is not the same as "unreviewed," and the fastest cases we see are usually the ones where someone checked the numbers before anyone signed anything.
What Actually Makes a Divorce Uncontested
Illinois has been a pure no-fault state since 2016, so every divorce, contested or not, proceeds on irreconcilable differences. What separates an uncontested case is not the ground for divorce but the absence of any disputed issue: property division, debt allocation, maintenance, and, where there are children, parenting time and decision-making, are all resolved by agreement rather than litigated.
That agreement still has to cover the same ground a judge would otherwise decide. A case is only uncontested for as long as both spouses agree on all of it. If one issue is unresolved, whether a retirement account, a business interest, or a parenting schedule, the case is contested on that issue even if everything else is settled.
The Marital Settlement Agreement and Parenting Plan
The agreement itself takes the form of a Marital Settlement Agreement covering property, debt, and support, and, where there are minor children, a parenting plan allocating parenting time and significant decision-making under the same best-interests framework used in any custody matter. Illinois still requires both financial affidavits and, if applicable, a completed parenting education class before judgment, even when nothing is contested.
Cook County reviews the agreement at a brief prove-up hearing rather than a trial. The judge confirms both parties understand and voluntarily accept the terms, then enters judgment. Many counties, including Cook, allow this appearance to be done remotely.
Illinois’ Joint Simplified Dissolution Track
For a narrow category of marriages, Illinois offers an even faster joint simplified dissolution procedure under 750 ILCS 5/452. It is built for short marriages with no children of the marriage, no real estate, and modest combined income and marital property, where both spouses waive maintenance entirely. Because the thresholds are narrow and periodically adjusted, eligibility should be confirmed against the current statute rather than assumed from a prior case.
Most uncontested divorces we handle do not qualify for the simplified track, usually because a home, a retirement account, or a child takes the marriage outside its scope, and instead proceed as a standard uncontested case under a negotiated settlement agreement.
Why an Agreed Case Still Needs a Careful Review
The risk in an uncontested divorce is rarely the process, it is the agreement itself. Without formal discovery, an uncontested case relies on both spouses voluntarily disclosing what they own and owe. We still review the financial affidavit line by line, confirm valuations on anything material, and check the settlement against what a court would actually be able to order, because a signed agreement that shortchanges one spouse is difficult and expensive to undo once judgment enters.
This matters more, not less, when the marriage involves a business interest, equity compensation, or premarital property, the exact situations where an informal handshake agreement is most likely to miss something.
How Long an Uncontested Divorce Takes in Illinois
Once both spouses have a signed agreement and the case meets Illinois’ 90-day residency requirement, an uncontested divorce can conclude within a few weeks of filing, limited mainly by the court’s prove-up scheduling. Cases that stall usually do so before filing, while the agreement itself is still being negotiated, not after.
