My Dad is in the latter stages of Alzheimer's and he's in an assisted living facility in North Carolina now. One of my sisters had power of attorney, but I've since learned that it was transferred to another sister. I'm sure if it was done legally or not. My two sisters have taken my name off the list people allowed to call and inquire about my Dad. The reason they've done this is childish. The reason is because I haven't done what they feel I should have done by visiting my Dad. I live ten and a half hours away from my Dad. Is it legal for them to do this?
