recent widow

My husband recently died. He had three credit cards in his name only. I called all three card companies and they said that I did not have to pay the bills that were just in his name.

Now I receive a bill from a collection agency for Chase credit card. We have one account that is in both our names and is only has $l41.00 in it. We have a living trust and a reversed mortgage on our house.

Do I owe for his credit cards?
