My Father in law called wanting us to buy them a new house or give them $5,000. immediately and 1500$ a month. What? We live on a very modest income. We are diy people , drive old cars etc. They have been terrible with money. My husband and his brother told FIL to sell house but dementia ridden. MIL won't let anyone in the house.( she has had no treatment ,won't go to the Dr.,leave the immediate area, and is abusive to FiL) . We've been told to stay out of their medical and financial business for years even though we've tried and tried. My husband wants POA before they get one dime since they can no longer be trusted. Is this a reasonable request ? If they refuse which is likely will they be homeless?
