re: Can I sue my ex wife for half of mortgage payments made?

Did your attorney have the repayment stipulated in the court proceedings / divorce decree?

It sounds like your attorney either screwed something up, or gave you bad advice.

I don't see how you can be entitled to any reimbursement for the time you were married. Community property is community property. Again, if you wanted to keep all the proceeds from the house, why was this not negotiated and put in the legal proceedings.

A good friend of mine is getting everything finalized on his divorce this month. He is walking away from the house and his equity/payments in it, in exchange for other assets. There are some other joint debts that he is being relieved on, as they have been, or will be before the divorce is finalized, being refinanced so they are only in his soon to be ex's name.
