I had a credit card which I allowed my wife to use as an authorized user. It was not a joint account, she was just an authorized user so she had her own card with her name on it, but the account was always in my name exclusively. The balance is about $10,000 and I would say 25% of that comes from my purchases and 75% comes from her’s (I still have to go through all the bills to pin that number down to an exact amount).
So we agreed to separate, and she called the company removing her name as an authorized user from the card. Is she still responsible for her debt, or am I stuck with it since the account is exclusively in my name?
