When Can Spousal Maintenance Be Terminated in Illinois?

 Posted on September 23, 2026 in Spousal Support

Spousal maintenance, which most people call alimony in Illinois, ends automatically in some situations. However, it doesn’t stop on its own just because paying has become difficult. If you have questions about ending or modifying your maintenance order in 2026, our Kane County, IL alimony lawyers can tell you whether your situation allows for it.

What Events Automatically End Spousal Maintenance in Illinois?

Under 750 ILCS 5/510(c), the obligation to pay future maintenance ends when either party dies, when the person receiving it remarries, or when that person lives with someone else on a resident, continuing conjugal basis. These apply unless your divorce judgment or written settlement says otherwise.

The statute uses the phrase "by operation of law," which means the obligation ends on the date of the remarriage or the date the court finds cohabitation started, not the date a judge signs an order. If you kept paying after that point, you are entitled to be paid back for those amounts.

Death and remarriage are usually easy to establish. Cohabitation is more challenging.

What Counts as Cohabitation for Alimony Under Illinois Law?

Illinois does not define cohabitation with a checklist. No single fact decides it. Judges look at the whole relationship to determine whether it functions like a marriage. Common considerations include:

• How long the relationship has lasted

• How much time the couple spends together and whether they live in the same home

• Whether they share money, bills, or accounts

• Whether they vacation together and spend holidays as a couple

• How much their daily lives and personal affairs overlap

Dating someone, or even seeing that person often, is not enough. The burden falls on the paying spouse to prove the relationship crossed the line into cohabitation, and to show when it started, since that date controls how much money is reimbursed.

When Does Maintenance End Because the Term Runs Out?

Under 750 ILCS 5/504(b-4.5), a judge must classify maintenance as one of three types, and the type controls what happens when time passes.

Fixed-term maintenance ends on the stated date, and further maintenance is barred after that period closes. Indefinite maintenance has no end date and continues until it is modified or terminated. Reviewable maintenance runs for a set period and then comes back before the court, where a judge can extend it, convert it to a fixed non-modifiable term, make it indefinite, or end it permanently.

Can a Court Terminate Spousal Maintenance Early in Illinois?

Courts can terminate maintenance early but only on proof of a substantial change in circumstances. They look at factors including: 

• Any change in either person's employment and whether that change was made in good faith

• The efforts the receiving spouse has made to become self-supporting

• How long maintenance has already been paid compared to the length of the marriage

• The property each person received in the divorce

• How each person's income has changed

Retirement is the most common example. A payor who retires at a normal age and in good faith may have a real argument. However, a court can still order maintenance to continue if that person holds enough assets to pay it.

Illinois does not allow changes to payments that came due before the other party received due notice that a petition to modify or terminate maintenance had been filed. If your income dropped six months ago and you file today, those six months of payments still stand.

What Should You Do if You Think You Have Grounds to End Maintenance Payments?

The most important thing to remember is that you should not simply stop paying. Unpaid maintenance becomes an arrearage that a court can enforce, with interest, and a judge can hold you in contempt. Filing first protects you even if the process takes time.

Start by gathering what supports your position, such as a marriage record, lease or utility records, social media posts, photographs, or financial documents showing a shared household. For a change in circumstances, that means tax returns, pay records, medical documentation, or retirement paperwork.

Your petition is typically filed in the court handling your divorce case. If your case is in Kane County, that is the 16th Judicial Circuit.
