Right on grandfather's property

Indian law concerning Hindus is very clear that self-acquired intestate (no will made) property only of the deceased male/female Hindu is inherited by his/her sons and daughters in equal proportion along with the surviving spouse. The grandsons or granddaughters have no right to inherit or claim any share in the property of the grandfather or grandmother if their own father or mother are alive. The grandchild does not have a birthright on the self-acquired property of the grandparent

        Your grandfather's legal heirs, that means your grandmother, your father, uncles, and aunties if any.  Grandchildren have no right.
