My grandmother's original will stated that her assets would be divided equally among her 5 children(my father is one of them). A year ago, my father passed away suddenly due to cancer. During this time, Grandma's health has diminished substantially as well and hasn't been able to take care of herself since the funeral. My initial inclination was that I (as my Father's only child) would stand in for him in the event of Grandma's passing and inherit 1/5 of her estate. My Uncle recently came by the house asking for a copy of my father's death certificate. I innocently asked why he needed it, and he plainly said that he was attempting to remove my father from Grandma's will. Grandma is in no state of mind to handle her affairs, so my uncle has been doing it. But can he do this to me?
