I have two brothers. One brother has POA and is the executor of my mom's estate. He also handles her investments and finances. At this point he is not sharing any information with me or my other brother about any of this. I would like some information in the event he were to pass away before my mother, or he he is unable to carry out his responsibilities. Do most families have a back up plan? How do you handle these things? He is unmarried and has no children. As far as I know he is the only person who knows anything regarding my mothers affairs.
