Hi, I have joint POA with my brother for my mother who has late stage Alzheimers with no capacity. My brother and I have fallen out completely and despite many attempts to ignore his bullying behaviour and move forward, I am now at a point where I feel the relationship has broken down so much that it needs to be dissolved. I cannot step down as I cannot trust his judgement for my mothers care and although I have asked him to step down he has refused. I have asked the OPG for advice but they say that unless he acts in a way that is detrimental to my mother welfare, he cannot be forced to step aside. We argue continually over every little decision that has to be made, he does virtually none of the tasks needed but argues against every decision that I make. Please can anyone advise on my next step?
