<prompt> Human: A paid-off Sallie Mae account of his turned ten years old, so it fell off which I guess is the norm? so since that was the only thing on his credit, hes back to no credit. I have a credit card with my credit union and a car payment with Ford Motor Credit on my own credit. His name is on neither one of these. Im going to look into adding him to the credit card, of course, but I am wondering if anyone can tell me how to add him to my car payment if its even something I can do? AND if theres a way for Sallie Mae to put their account back on his credit if possible?  <response>: Make him an authorized user on your cards
