I have an aging father who is a widower. His state of residence is Missouri and mine is Florida. His wife had set up a will prior to her passing that includes my father's children, myself and a brother. Upon the death of my father, the will would be designated accordingly. I have attempted to have a clause inserted to the effect that if I should precede my wife in death, that she would receive my portion of the will after the passing of my father. My father and his attorney; who is the executor of the will, have both insisted that this is not possible given the directives of the will. Please advise me as to whether I may legally pursue this any further. I would; naturally, want my wife to be protected financially as we have no life insurance. Thank you.
