Thanks for the clarification.
Is his name still on the papers?
Here is the way it works legally
It is her house and per the decree she is responsible for the payments
however, they are both on the mortgage (unless she refinanced in own name which I doubt)
so mortgage co can get judgment for deficiency against them both
any money that he ends up paying, he sues her for under the decree and she can be held in contempt for failing to make the payments. (However she is most likely judgment proof)
if she couldn’t afford it, she should have sold it, paid the mortgage and bought something she could afford
The lawyer adds Dwyane has no further responsibility, but it seems likely he signed the mortgage papers in the first place so, as they say, tell it to the bank.
I suspect he could care less about the hit to his credit rating. He apparently would prefer that over giving his ex any more than he already has. Looking at the picture I think he is probably justified. Since he was awarded custody of the children she most likely is a worthless POS.
