My father is ill and another family member has recently been made financial and medical power of attorney, citing the reason that I don't live nearby. I feel that the family member persuaded my father into this and that they this person is untrustworthy and will be even more so in the event of incapacitation or death. He states that his will leaves everything to me as his next of kin but I feel that this family member will make sure that I don't get it in the end. Is this a possibility? What do I need to worry about and how should I protect myself and his grandchildren in this scenario?
