HiIf you have P of A for health and wealth, could you not speak to the bank and raise your concerns. My mum's building society were brilliant with her. We were concerned she was being taken advantage of financially. And they had dedicated staff to deal with dementia, with safeguarding policies in place.
We also got social services involved, a lot of the time we didn't necessarily tell my mum the full truth if we were trying to get her examined as she would dig her heels in, but the help she received whilst living on her own was great, until she was a liability when we had her move in with us.
It sounds like you have a battle with your brother too, which doesn't help. Good luck and I hope you are able to sort something out.
thank you for that.
there is no health welfare poa I’m afraid.
