Liability for deceased husband's bills

Hello. I am a Maryland barred attorney.  I am sorry to hear of your husband's illness.  Unfortunately, an attorney will need more information to adequately answer your question.  Whether a creditor can attach a house to pay bills depends on how the house is titled, whether you gave a security interest to anyone and whether the creditors have gotten judgments.   Depending on how a house is titled, a married couple may protect it in Maryland from one spouse's creditor , but figuring this out requires actually looking at your deed and the debts.
