Your question is VERY vague and probably more important than waiting for answers from Realtors on a web site.
If you think your home is in foreclosure, I suggest you contacting the mortgage holder to see if they have proceeded with a foreclosure, and/or call the county sheriff's office for some more information.
However, you should have received mail notifications of the pending foreclosure. I also suggest you contact an attorney to help you figure this all out.... more
Your SO needs legal advice immediately! He may need to hire a new attorney if his current divorce attorney can't get him out of this mess.
Right now it sounds like your SO is in contempt of court and could be arrested if he fails to make the mortgage payments as mandated by the judge. I'm not an attorney so he needs to talk to an attorney asap.
Also because he no longer lives in the house, he may not be able to get "owner-occupant" low rates...not sure how that all works.
Main thing, he need a judge to order his wife to sign the refinance paperwork if he can get in a lower interest rate. His credit will not be destroyed unless he fails to follow the terms of the court order!
