Can I file without my spouse filing?

For joint debts, if one spouse files and the other does not, only the filing spouse receives a discharge, and the non-filing spouse remains liable.  In this situation, therefore, it is necessary for both spouses to file in order for both spouses to be discharged.  However, if the debts are those of one spouse only, an individual petition can be filed on behalf of the debtor spouse, and the non-filing spouse will not be liable for the debt.
