Death being certain & it's time uncertain, it is very essential that the hard-earned assets one earns are secured. As per law, disposition of estate of a person on his death takes place as per Hindu Succession Act which consumes time. Besides it is uncertain as to how disposition takes place. Similarly in case of minor children it is uncertain as to who takes care of them. To ensure disposition of property by inheritance calls for huge expenditure. By executing a will one can ensure disposition of his property in almost 1/5 or 1/10 of the amount it takes to be expended otherwise.
Will is the legal declaration of intention of testator with respect to his property after his death. So will can even be handwritten & the registration is not compulsory. However handwritten & unregistered will is at risk as follows:
Will in order to be valid has to be properly executed and in consonance with provisions of Indian Succession Act. Laymen are not aware of these provisions. Besides a will if not properly executed is prone to be challenged, again causing huge expenditure for defending court case.
