Credit score

My husband and I divorced in 2018. We each had our cars but in both of our names. In our decree it states that we are each financially responsible for our own vehicles. But the loans are in both of our names. He has been late on his truck payment several times. Affecting my credit score. Being this is in court documents and states in our decree that he is financially responsible for this loan court ordered, is there a way to get my name off the loan or off my credit with the court papers only to the credit union without him refinancing the truck to remove my name? He is unable to refinance due to his credit. Thanks for all feedback
