Can anyone out there respond to my question???

My ex and I are divorced and in the divorce decree we had to go through ED and during that process the judge gave the truck (in both names) to my ex. Judge told him to get it out of my name when he could. It’s been 4 years and he has made no effort to get it out of my name. What can I do to get this matter taken care of? I’m trying to get a loan for a house and his late payments on the truck are showing up on my credit report and it’s giving me a low credit score. I need some advise as to what I can do to make him get this out of my name, since the judge gave him the truck during ED court. I need some good advise and I need this out of my name ASAP. [:(]
