Last year I made my brother an authorized user on my Discover card. He lives in Georgia while the rest of the family lives Virginia so I made him an authorized user so he would have something to fall back on. Recently I recieves a phone call from Discover saying I was $24,000 over my credit limit and I couldnt understand why. My brother made payments on time and multiple times a month and never saw a problem. My brother finally out and told the truth, that he wasn't making the payments, his "friend" was. They got into an argument and the person called their bank and said all the payments to the Discover card were all unauthorized payments, so discover refunded the person all the money with no questions being ask leaving me to this big debt. All I those payments were authorized and I have purchases on the account linking the person. Ultimately this debt is mines being that it is my card but I wanted to see if there is anyway that person can be held liable for some of this debt? Also, do anyone recommend I take legal action against my brother?
