He’s foolish to pay his daughter’s student’s loans. She’s graduated and is responsible for her own loans.
But besides that, I think this case needs to go to the USSC. This can’t be legal to make one adult responsible for another adult’s bills, no matter if they are related by blood in some way.
What about the fact that the kids are the default inheritors? If we acknowledge that all other things being equal, the kids should receive the deceased parents' estates, then why is it unreasonable to assume they might have some liability accompanying that as well, or at least liability capped at the amount of any inheritance? If they're such completely separate entities, would you be willing to have the law changed so that adult children no longer inherit by default? Now I do agree that I don't think it's right for people to be asked to pay if the consumer is alive and refuses to pay.
