Duration of Alimony in Illinois

In Illinois, the duration of alimony, or spousal maintenance, depends on the marriage’s duration. In a marriage of under 5 years, maintenance payments last for 20% of the marriage’s length. For a 9-10 year marriage, alimony payments last 40% of the marriage’s length. 20+ years of marriage means alimony will either last the marriage’s length or indefinitely.

How Is Maintenance Calculated?

The Illinois courts award alimony, also called maintenance, based on need, ability, and any other factor the courts deem appropriate. Once awarded, they calculate alimony based on each party’s income. Use our alimony calculator to see what spousal maintenance payments could look like for you.

How Does Alimony End?

There are three reasons to terminate alimony orders in Illinois. First, using the above table, the court sets a date for alimony to end, and when that date is reached, it ends. Spousal maintenance also ends if the spouse receiving alimony moves in with a new significant other or gets remarried.

Finally, if there is a significant change in financial circumstances, spousal maintenance can end early. This is the hardest to prove, so having an attorney to help becomes even more important here. For any legal help on spousal maintenance, using a family law attorney such as one from Sterling Lawyers, LLC gives the best chance of success.
