I had to get a credit card with my name on it for my Dad's account. Am I responsible for any left debt?

If your signature is on the transaction, the collection efforts will be aimed at you. Never allow yourself to be a signatory on a credit card unless you are ready to pay off what you signed for.

Perhaps he is eligible for Medicaid. Didn't mean to sound snooty, but I've seen far too many cases of people intentionally running up debt and then walking away from it. I've worked the credit department of small companies making phone calls to people trying to get them to pay the bills. One example, a florist I worked for would have people buy all their wedding flowers and then say, well I didn't like this arrangement so I'm not happy and I'm not going to pay. This didn't happen but a couple of times before we made the decision to require full payment in advance rather than a down payment. A few people don't pay and then EVERYBODY pays.

So, this really doesn't answer your question of whether you'd be responsible. I think I don't know the legal answer to that. I would presume that his estate would be responsible.

unfortunately there was already a balance on it when I inherited my dad and don't want to get stuck holding the bag. It is my intention to pay it down as able but he does not have a great deal of income to cover all of his expenses. And thanks for the education and your opinion.

If you pay the bill each month when it becomes due, there won't be a balance.

In my opinion, people who incur debt, should understand that it will have to be paid, it is a LOAN. Why should the bank be left holding the bag?
