My parents added me as an authorized user to their credit card to shop for them because medical conditions made it hard for them to get around. My father passed away and this continued up until a few months ago. My mother is now in a nursing home and all of her Social Security and pension income is used to pay for the home. Am I responsible to pay her credit card debt? I just found out my brother used his Power of Attroney and had added himself to the same account several years ago. If I am responsible, isn't he equally responsible because he added himself to the account as an authorized user? I don't think I should have to pay her debts, but I don't know the law in this situation. Any help will be greatly appreciated.
