I cannot talk to my bro. we need to decide on many things for my mom. he lives out of state and wants to control everything. he will not answer emails , or texts. and I have given up because whenever he would reply there was always a "dig" , saying for instance that I do not have the authority or the judgement to make these decisions.. he is financial poa . i am healthcare poa. can i make the choice about things such as where my mom goes for TCU independant of him?
