Not sure about this as putting anyone as an AU will not affect their credit score. The person responsible for the AU is still the primary user. Thats why whenever you want to add an AU all the CC company wants is their name. I've never been asked for even the SS # for any AU and its the SS# thats needed to track one's credit history. Only having a joint CC acct where both are responsible will affect the other persons credit.
