If you are a co-debtor with your ex-spouse on a debt, the creditor can require the entire payment of that debt from your share of the marital property, even though the divorce decree assigns the debt to your ex-spouse. Depending on the terms of your divorce decree, you may be able to have certain support obligations determined to be nondischargeable by the bankruptcy court or in state court. You should seek legal advice for a thorough explanation of your rights and obligations in this area as soon as you find out that your ex-spouse has filed bankruptcy.
