My question involves divorce in the State of: Missouri

Hi, my divorced was finalized back in April, and in part of our Martial Settlement Agreement, she agreed to take on full financial responsibility of the 2001 Grand Am, which was financed under both our names. Under the M.S.A. she was supposed to take full financial responsibility of said vehicle within 10 days of the finalization of the divorced. Now 8 months later, my name is still on the loan, she has been late on the payment 8 times since we separated in January, and the vehicle has almost been reprocessed 4 different times. Also, she recently blew up the motor and I have no idea if she's getting it fixed, going to let it go or what she's going to do. Do I have any legal recourse I can take to somehow force her to get the car out of my name and is there anything I can do about the damage she has done to my credit by not keeping up with the payments? Thank you in advance for any help you may be able to provide.
