My uncle in Fort Lauderdale has been the prime caretaker of my elderly grandmother (age 81) for the last few years by his choice. He has spent all of her money, sold her car and rents out her house. He will not let any of her family see her or talk to her for reasons unknown. My mother and her other brothers would like to be able to visit her, and would like an account of where all of her money went. What legal action can be taken?
