I hate to tell you this... but regardless of what a divorce decree states, you still knowingly signed the same (I'm assuming 30 year) loan papers... all of the fine print that most of us never read says that no matter what, if one lessee fails to make the agreed payments, the other is still responsible for them. This is in effect until the loan is one of 3 things 1. Paid in full 2. Refinanced with your name removed 3. Assumed by one of the lessees in full.
When you were divorced, you had the option of contacting the lendor with proof that you were divorced and removed from the title to REQUEST that they remove your name... however it is entirely the lender's decision, and rarely does it happen that way.
At this point in the game, you are their only option to gain back some of their money... they are not likely to let you go. You should probably talk to 2 different types of lawyers: a divorce attorney to see if there is even the option to sue your ex for damages (though this is extremely costly and won't likely help you much financially... just may make you feel better) and a bankruptcy attorney to see if you are a candidate... I know that is rough, but unless you have the cash to bring the loan current and continue payments... you are in a bind.
