If you're losing sleep over a spousal maintenance payment you can no longer afford, you're not alone, and you may have more options than you think. Missouri law only allows a modification when your circumstances have changed in a way that's substantial and lasting, like a lost job or a serious medical diagnosis, and the court can only adjust payments going forward from the date you file. That means acting fast matters.

Life changes can make spousal maintenance unaffordable. Learn when Missouri law allows modification and how The Marks Law Firm can help you act fast.
