i am poa for my mother who has dementia and for both health and financial matters and am also her registered carer.My younger sister has announced that she and her son with learning difficulties want to move in with mother for three days a week only as this will not affect their or mothers benefits However she does not cook or do housework and has persuaded mother that they should eat takeaways on the three days.She of course wants mother to pay for it.Before i had power of attorney my sister used to come over and either steal or persuade mother to give her money.I know her aim is to take over mothers finances for her own gain and mother is so naive. Im at my wits end any advice would be much appreciated.Beryl UK
