He has a little dementia at times. How hard is it to revoke a medical POA. I can have an attorney be present when my father signs. I asked him today who he wanted and he said me not my brother. It is my understanding as long as I new papers are drawn up and my father signs with a witness I can revoke it.
As it happens, I believe that my siblings' motives are sound enough, and they do their best; but all the same it would make my mind easier if financial POA could not be held by any person with an interest in the estate. The law seems content to assume that people are capable of acting disinterestedly; well, I expect that most people do their best to achieve that. But to act on the assumption that your average person can easily set aside all considerations of financial gain, convenience and all the other ethical lapses that flesh is heir to… it's bonkers. There's got to be a better way of doing this.
Is your brother apt to contest this? If so, it is good to have an attorney involved.
