NC follows something called the "Doctrine of Necessaries" which means spouses are responsible for each other's debts if they were incurred for the benefit of the household. And medical bills are such a debt. Accordingly, the hospital can make a claim for the money against you and/or your husband's estate. At this point, I would recommend that you consult directly with a local attorney who can best advise you further. They may be able to help you negotiate with the hospital and possibly reduce the bill.
