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 duration. 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 Long Does Alimony Last?

The duration of alimony depends on the length of the marriage. To figure out how long your alimony will last, check the table below. Take the length of the marriage in years and multiply it by the associated percent to see how long the alimony will need to be paid.

Duration of Marriage (in years) Duration of Alimony
Less than 5 20% of the Marriage’s Length
5-6 24% of the Marriage’s Length
6-7 28% of the Marriage’s Length
7-8 32% of the Marriage’s Length
8-9 36% of the Marriage’s Length
9-10 40% of the Marriage’s Length
10-11 44% of the Marriage’s Length
11-12 48% of the Marriage’s Length
12-13 52% of the Marriage’s Length
13-14 56% of the Marriage’s Length
14-15 60% of the Marriage’s Length
15-16 64% of the Marriage’s Length
16-17 68% of the Marriage’s Length
17-18 72% of the Marriage’s Length
18-19 76% of the Marriage’s Length
19-20 80% of the Marriage’s Length
20+ 100% of the Marriage’s Length or Indefinitely[1]

While these numbers are in the Illinois statutes, the judge still makes the final decision.

Considerations

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 four 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 Hughes gives the best chance of success.

"I used SterlingLawyers.com for my child custody case. Having never been through this I had no idea what to expect or what the process was and was very nervous about the whole situation. My lawyer (Nikole) was very professional, straight to the point and took time to explain everything out to me which put me at ease. She took the time to talk to me every step of the way really listening to me and when it came to the hearing/agreement I got exactly what I wanted. Cant recommend SterlingLawyers.com enough."
