Always Nondischargeable
Domestic support obligations -- child support, spousal support, alimony, and maintenance -- are never dischargeable in any chapter of bankruptcy. This is one of the few absolute rules in bankruptcy law.
Priority Status
DSOs receive the highest priority under Section 507(a)(1). In Chapter 13, they must be paid in full through the plan. In Chapter 7, they survive discharge completely.
Discharge Requirement
Under Section 1328(a), a Chapter 13 debtor must certify that all domestic support obligations that became payable before or during the case have been paid in full before receiving a discharge. If you are behind on support, you cannot receive a discharge until you are current.
