Is there anyone out who knows anything about VA mortgage loans?

I have called the Va mortgage center for days and no one has called me back yet. My husband is a veteran and he had a va mortgage with his first wife and she kept the house after they seperated and couldn't make the payments. We don't know if they foreclosed or sold it or what ever. She didn't tell him anything. How will he know if he qualifies for another va loan with me (his new wife). Can anyone give me some kind of answers? What is the worst case senerio?
