My dad is 90 and lives in a retirement home, 3 hours away from where I live. I have 2 older sisters, the eldest has Power of Attorney. She has acted in that role for at least 2 years, if not slightly longer. Middle sister and I feel she is secretive. While my dad may still have some level of competence; he shows signs of memory issues. I emailed the eldest sister asking for information about my dad's estate. She (expectedly) accused me of trying to start a fight... That response only leads me to be concerned that there could be some malfeasance. Any advice regarding the best way to proceed? (I am about to respond to her email... but I know she will only fail to give me information which all 3 offspring should have). By the way, I discussed this with my dad and he told me that all 3 of us children are equally entitled to know this information. (However, due to his frailty, I believe that my eldest sister can manipulate him). Any advice? Thanks.
