I have a bankruptcy liability question - (see details)

I’m filing for bankruptcy, but I have a question about my dad’s liability: I’m “on” his credit card. However, I’m not the account-holder; the account is in his own name, but has my name on the card. I receive no bills/mail/anything. I talked to an attorney regarding this issue, and it looks as if I’m in the clear, or more importantly, he is. Still, I could use some reassurance from anyone who has filed before, or has some experience as someone who’s had a family member file? Also, I’m in New York if that affects anything, and it’s an American Express card. Thanks!
