There are cases where the creditor went after an AU for the entire debt. From what I have read, it is mostly when the AU makes a purchase on the credit card after the primary cardholder's death, even if that purchase was for funeral expenses for the primary card holder. The AU needs to be very aware that if the primary card holder passes, that the account needs to be closed immediately. So if a parent passes away and the child uses that card as an AU to purchase airline tickets to come home from college due to the parents death, the creditor can then go after them for the entire debt. Just so many scenarios that I would not want to even put my kids through. My son passed away less than 3 months ago at age 24 so these things are things that I think about now when making financial decisions that may impact my other children.
