I had a divorce 5 years ago, separated 7 years ago. My ex husband had a car that a was a secondary borrower on. When we separated, he kept the car. A year later, I was aware that he had it repossessed although I was never contacted by anyone about it. My ex told me he went to court and made an agreement to pay $7000 as full and final payment (the amount outstanding was $12,000 I think). My ex told me that he has paid the amount agreed to. I was never contacted by the collection agency thoughout this time however just recently I have found out it is listed on my credit file and yesterday I was served a claim for $14,000 for this debt. This is the first time I have been contacted. The debt collectors informed me that my ex has not paid 1 cent of the money he told me he paid. My question is can I fight this or do I just have to pay for my ex's car? Thank you
