If you were the second card holder on credit cards under your husband's name are you responsible for the debt if he passes away?

Yes you are. Call your credit card company (hopefully your husband is not deceased) and ask them about insurance to provide protection for such a thing. I have it on my husband and my own credit card. This way if one of us should pass away it is automatically paid off to a certain limit (I live in Canada and it's usually up to $15,000.) If your husband has passed on you automatically get the house, properties, etc., unless otherwise specified in his Will. All taxes on properties (if the properties are not in your name as well) are paid and all debts are paid by action of Probate. What is left over is yours. If you and your husband had joint ownership in everything then it's fairly simple. Go to your banking insitution and they will certainly help you out with these matters. Marcy
