What are my options regarding my ex's name on my car loan?

My divorce was just finalized and the court awarded me the car but the loan is in my ex's name. The bank still holds the title. As the payments are high and not something I can afford, I want to know my options. The bank that financed the car does not offer refinancing and when I looked into it my payments did not decrease. I would like to be able to purchase a car that is more affordable but I am stuck with the loan in his name (and helping his credit rating by making the payments which is why he will not cooperate with me to find a solution).
