My Mother was the primary bill payer for my parents for almost all of their marriage. During the last couple of years of her life, she was starting to battle dementia and ran up big credit card debt on two cards, often paying one bill with the other card. Since her death last year, my Dad now has big debt on both cards ($15,000 on one; $9,000 on the other) that he cannot pay. He can't even make the minimum payments on them, and now the one with the larger debt is suing him for the balance. He has no assets, so even if they sue him, they won't get anything. What do I do now? Do I seek legal help?
