My mother has lung cancer, currently lives with my sister. Only assets she has are a paid-for Ford Focus, her clothes and inexpensive jewelry, $5,000 in the bank, a $5,000 life insurance policy, a small pension death benefit, and Social Security. She is currently charging all her expenses on credit cards, because my sister is unemployed and can't contribute other than keeping the roof over her head. What will happen when she dies and her credit card bills exceed her assets?
