My Grandfather bought a house of 1600 Sq.yds, after his death his wife and her 7 children decided to divide the house hence the youngest son filed a suit for partition in the court .My father who was the eldest son along with his six siblings and mother each was awarded a Plot of 200 Sq.yds. Now my father passed away last year on 3/12/2009,after his death my mother and we three children survive, my mother wants to make a will to gift her share out of the property to elder brother since he is mentally slow. Can she execute a will in his name which is legally valid if so how and what is the format.
