My father had a massive stroke in July 2016 and lost his memory. The doctor says is permanent memory loss. He and his elderly wife live with my sister. My father has a joint account with my sister. His SSI and his all his finances my sister controls. She refuses to give his elderly wife a dime. I am paying the wife cell bill to help her out. Yet, I feel bad for the wife because she is afraid of my sister. I have advised her regarding giving the wife her share. I have no idea why my sister is hoarding my father's money. The wife can use money for her personal needs. I have been involved giving advise and helping in any way possible. However, I am stepping back and let them deal with it. My sister has cut communication with me. I have no plans to take legal action. I want to know what is the wife legal right. She speaks broken English. She is vulnerable. She is the one taking care of dad day and night without any compensation. Please, I can use some suggestions. I want to help without being mean and problematic. Thanks for your suggestions.
