You are not obligated to the creditor for your spouse’s debts. However, debts that were incurred by either party during the course of the marriage are presumed to be “marital” and responsibilities for marital debt will be allocated equitably between the parties. There are, however, various reasons that the presumption will be rebutted, including when one party receives the benefit derived from the obligation and equity demands that the party receiving the benefit be responsible for the obligation.
