Your wife or husband will not be affected by your bankruptcy if they are not responsible (did not sign an agreement or contract) for any of your debt. If they have a supplemental credit card they are probably responsible for that debt. However, In community property states, either spouse can contract for a debt without the other spouse’s signature on anything, and still obligate the marital community. There are a few exceptions to that rule, such as the purchase or sale of real estate; those few exceptions do require both spouse’s signatures on contracts. But the day to day debts, such as credit cards, do NOT require both spouses to have signed.
