Hello My two brothers and my son are executives and power of attorney for my mother who lives in a self contained unit in an old peoples establishment. She is quite wealthy owning some assets,one asset she lives off the money she is paid every year from a mining adventure on the property,which keeps her well looked after. She has been generous over the many years in giving large amounts of money away to my two brothers and my son and daughter,I am a blacksheep and have never seen a cent. My mother's memory has been fading for sometime and the last couple of months she has been very confused and her memory is not good at all.My son rang me recently and told me that one son had been to her place and had taken her cheque book and a copy of her will.This son is not mentioned in the will as he has received very large amounts of money from her in the past 2 years and a property. My son tells me he went to her bank and was told that one of her smaller investments had matured and there was only a few thousand left in that bank account.Where do we stand if this brother has got my mother to sign a cheque for his benefit,knowing she would of forgotten she has even done so.As mentioned above my two brothers and my son are power of Attorneys,when does the power of attorneys take over so this practise of one of them stops getting his mother to sign cheques in his favour.Is it too late to do something about the cheque my mother signed in this one brothers favour.Thanking you.
