My brother had my dad sign a POA days before he was deemed of diminished capacity following a stroke. He is also the trustee to my dad's estate and has not included me in any decsions regarding my dad's care or his financial affairs. My children and I are all beneficiarys of my dad's estate yet we have been left totally in the dark and are not able to see my dad without him or my only other brother (who he has named caregiver) present. I have never harmed my dad, there is no restraining order or any other factual basis for such restrictions. I feel this a a gross issue of control and abuse of his role as trustee and POA. I would like to challenge his actions and would like guidance on how best to approach.
