Couldn't happen in Florida
Or Texas either!
Or Minnesota. Even if one spouse has the deed and owned the property before the marraige, you can't sell without both spouses appearing at the closing with picture ID's and signing the documents.
I think it's the same or similar in most states. But if her name wasn't on the deed, what's to say he just didn't claim he was single or divorced and their was no wife in the picture? Of course that meant he committed fraud, but what did he care? He was leaving the country anyway and he knows his muslim country isn't could to extradite him back to the US.
If the house is in his name, and he doesn't volunteer that he's married (or lies), and is out of the country immediately after the sale, what is the recourse?
