If you are a co-obligor with your ex-spouse on a debt, the creditor can require the entire payment of that debt from you 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 under it determined to be non-dischargeable 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 a bankruptcy.
