Legitim. Mother had 3 sons, 1,2 &3. Son 2 died leaving one daughter and one son. Her will leaves house to be sold and divided 50% to son 3 and 25% each to daughter and son of son 2. Moveable estate to be divided equally between son 2's daughter and son 3's wife. Son 1 wants to claim his share - legitim. We believe he would be due 1/6th of the moveable estate. Can son 3 and son 2's daughter and son also claim legitim. Do they lose any rights to share allocated to them.
