Generally speaking, courts allow settlement agreements as full and final resolution of the issues before them. The parties are generally asked if they fully understand the agreement and if they signed the agreement voluntarily and knowingly. Only after the court is satisfied, is a final order entered based on the agreement. In view of all of these circumstances, it would be an extraordinary case in which a final agreement would be overturned.

I agree with the response you were given and I wanted to build on it. If the ex-husband stops paying, the ex-wife could ask the court to hold the ex-husband in contempt of the order which incorporated the settlement agreement. As to how the money is paid to the ex-wife is very fact specific and unemployment of the ex-husband could possibly be factored into the rate and amounts of payment.
There might be some preemptory steps the ex-husband could take to prevent a contempt action being filed against him. I recommend that you sit down with an attorney and discuss your situation. My law firm, Smith Bivek Law Group, provides a free legal consultation in a private and confidential environment.
Thank-you, Melanie Brubaker
I note that you asked the same question on another site and the answer there is correct (and the same as the answers here).
You can't redo the settlement agreement. When someone makes the costly mistake of not using a lawyer in a divorce you don't get a "re-do."
She could file a contempt and even have him jailed if he fails to comply, or she can seize his assets and income, or do other things to him.
Your question presumes the agreement was unfair ... but I am not sure why. Both parties agreed to it, it was not imposed on them. You don't mention any coercion or other circumstances to indicate that the agreement was not entered into with a full and complete understanding, and meeting of the minds.
It is highly unlikely that equitable distribution of property, agreed upon and incorporated into a court order, can later be modified. There may be other ways to skin this cat, however, which can be developed by an attorney with a full understanding of all the facts and circumstances. Sounds like it may be worth a consultation, which many firms, including mine, do free.
