4 Siblings and our younger sister was given the POA, will, etc... My brother and myself are okay with that. Suddenly older sister is wanting copies of everything. She refuses to have mom stay with her, does not help and maybe twice a year takes her to lunch. Is my younger sister required to give her copies of everything? She has resented our mom for decades and now with our mom's health declining she is trying to get information. Thank you for your time!
