My uncle was taking money out of my nana's (his mother's) bank account via internet banking. Nana found out about this and called a family meeting in which his 3 sisters attended, but he declined. Nana was very distressed over the thought of her own son taking advantage of the position of executor of will and guardianship over her money. Just a couple of weeks after this meeting, nana's health declined and she passed away. Nana never got a chance to do anything about the stolen money. Now my uncle is the executor of the will and power of attorney. He is stating that the money that he transferred from nana's bank account to his was a gift. My aunties (his sisters) are upset that he is getting away with ripping my nana off. Is there anything my aunties can do legally now to make him pay back the money?
