If your husband is not personally responsible for debt, he will not be responsible after you file bankruptcy either. The only debt he can be held responsible for is debt that he himself incurred, either as borrower or guarantor. In other words, if a credit card is in your name only, and you file bankruptcy, your husband will NOT be responsible for the debt unless his name also is on the credit card. Good luck!
Your husband will be responsible for any of your debt that he co-signed. Any debt that the both of you took out together he will now be responsible for. Contact a lawyer so they can review your debt and tell you if your husband will be on the hook for any of it.
