save my good credit from x-hubby

What is the name of your state? arizona

I was divorced Dec. 99. Divorce states x-husband to take car and have it refinanced in his name only. He didn't. Now he is filing Chapter 13. Bof A called me to remind me of late payment not knowing that we had been divorced for 2 1/2 yrs. Car is valued at 10,500...he owes 14,500. Never had one late payment before.

His plan sent to me by court states a value offer to BofA of the 10,500...can they or will they come after me for the difference? Am I able to repo the car (my name is on title and loan papers) and sell it myself? My credit is still good and I have good business with the bank. What if I offered them ..say...11,500. Can they negociate since my name is on the docs?

What if he doesn't make the restructured payments? Can the bank negociate with him and still come after me for the original amount?
