Can an Illinois Divorce Case Be Reopened Years Later?

 Posted on May 22, 2025 in Family Law

A divorce decree is typically the final chapter in a difficult story. But what happens when a major twist comes years later? Maybe a hidden asset surfaces, or a former spouse fails to follow through on the agreement. In Illinois, divorce judgments are designed to bring closure, but they are not always set in stone. Under certain legal conditions, the court can revisit and even reopen a divorce case long after it has been finalized. If you are dealing with unexpected complications after your divorce, a Naperville family law attorney can help you explore your options based on your circumstances.

What Legal Grounds Allow a Divorce Case to Be Reopened?

Illinois law does not easily allow divorce cases to be reopened, but exceptions exist. The court may revisit a case when compelling reasons exist, such as fraud, mistake, or newly discovered evidence.

If you believe that you have grounds to reopen a case, it is important to act quickly. Most motions to vacate a judgment based on fraud or mistake must be filed within two years of the original ruling. However, actions to enforce or modify support or custody can remain open longer, depending on the facts of the case.

Can Property Division or Support Orders Be Changed Later?

Property division orders are generally final and cannot be modified after the divorce is complete, except in cases involving fraud or procedural error. However, other parts of a divorce judgment may be subject to change as circumstances evolve.

For example, child support may be adjusted if one parent's income drastically changes or if the child’s needs evolve. Parenting plans can also be modified if a substantial change affects the child’s best interests.

As for spousal maintenance, the court may change or end it if the receiving spouse remarries or lives with a new partner. A loss of income or other financial changes may also support a modification request.

What Should You Do if You Need to Revisit a Divorce Judgment?

If you believe your case should be reopened, your first step should be to consult with a divorce lawyer who has experience handling post-decree matters. It is important to understand that the court will not automatically reconsider a finalized judgment—you must file a formal petition and provide credible evidence to support your request.

To build a strong case, be prepared to gather any documentation that demonstrates fraud, changed circumstances, or non-compliance. An attorney can guide you through this process and help ensure your motion is filed in a timely manner and supported by the necessary facts.
