Question:  Why am I still responsible on a car note, when my spouse was ordered to pay for it in the divorce decree?

Answer:  Since the car was community debt, and it was repossessed from your former spouse, the bank is now looking to you to pay the deficiency. The deficiency is the amount the bank is still owed on the note, after the car was sold at auction. They can do this because your name is also on the note, and therefore you agreed to be responsible on the note. The bank was not involved in the divorce proceeding, and the agreements about who pays for the car are just between you and your spouse. And your spouse has failed to pay the obligations contemplateed by your decree.
