Power of attorney for my mother with dementia by sibling who does not have permission. I am a full time carer for my mother, who has cancer, vascular dementia and other illness, so she is wheelchair bound. My siblings do not help or visit mum, and do not talk to me. Both are driven by money, and are very sneaky to put it mildly. Last year one visited, and tried to get mum to sign some power of attorney papers without my knowing. Mum did not sign. No one has power of attorney for mum. Today mum received a letter saying my other sibling had requested mums bank account be made paperless. But this was from a bank that mum has no dealings with, and has never had an account there. She is very loyal to her own bank, where they know her and look after her. Alarm bells are ringing. Where do I go to find out what my sibling are up to? I love my mum, and caring for her is a struggle enough, with out having to cope with tricky siblings. Any help and advice would be gratefully received. Thank you.
