Answer
(Fatwa: 127/155=D/1429)
Father died before grandfather and grandfather died later while his other sons (uncle of the grandchildren) are alive, in this case the grandchildren will have no share in the property of grandfather. If grandfather died leaving no son, then write in detail whom he survived.
(2) In a man’s property his children, wife and parents have shares. If one leaves children behind then his brothers (uncle of his children) will not have any share. You should write down the detail, and then we can write the answer.
