In my divorce seven years ago, my ex was given the responsibility of paying off a Discover card, which he did not follow through on. A few months ago, I received a call from Credigy holding me responsible for this debt, which now stands at over $9,000! This is the first I knew it hadn't been paid. Since I was the primary card holder, Credigy reps claim that they can take ME to court for this debt that a judge had ordered my ex to pay. The debt is over 7 years and we are in the state of Missouri. What are my options?
