What is the name of your state? California. My husband and I have been married 3 years. About a year and a half ago we decided to apply for a mastercard only to be turned down for poor credit. WE applied for a credit report and found out that his ex wife kept one of their joint cards- that, according to the divorce, was supposed to be payed off (He can prove he payed it off) and destroyed. She had the address changed so the bills would go to her apartment and never told my husband that she started using the card again. She ran it up to $3400 and quit paying on it- if she ever did. Since his name is on the card, Discovery insists he is responsible for the debt- even though all of the purchasses were made after the divorce. Hubby has contested this, has written a letter and it should be in his file but so far he has not been able to get anything but a $300 credit card (which the company will not increase even though he has paid on time or paid off early for 2 years now) We did what we were told to do but it has not resolved the problem. This is the only mark on his credit and we want if completely gone. How do we do it?
