Death of executant of.unregistered will

An unregistered will is valid if it conforms to the legal requirement of two witnesses who have signed the will in the presence of the testator and the testator has signed the will in their presence. So if these essentials are not fulfilled then the will cannot be held valid. Under section 18 of the Indian Registration Act, there is no condition which mandates that a will is required to be registered and hence there exists no debate over the actual validity of an unregistered will since the same is valid whether registered or unregistered as long as it resonates with all the points regarding the validity of a will.
