My father is 88 and my stepmother is 68. My father has a form of dementia and short term memory is failing quickly. Confusion comes and goes with him. He got into some financial difficulty by doing cash advances for gambling and found himself $16,000-20,000 in credit card debt. My stepmom says he's paid on that debt and has it almost all paid off. She took over taking care of his finances a year or 2 ago(after the credit card debt problem). I feel that he should share in household expenses since he lives there, but two of my brothers were not happy when they married 13 years ago. When my father passes away, I don't want that to be a time when they start questioning his finances/assets. How do I approach the subject with her so it doesn't look like we don't trust her with his finances? Thank you for any suggestions you can give.
