Causes of unworthiness of the heir or of legatee

Those who have been convicted of an attempt on the life of the testator, or of abetting in any manner in such crime, and those who have prevented the testator by violence, or threats, or fraud, from revoking his Will, are barred from taking benefit of the dispositions made in their favour. § Sole paragraph – However, in the case of an attempt against the life of the testator, where he survives, the disposition made subsequent to the crime shall be valid where the testator has knowledge thereof, and the prior disposition shall have effect as well if the testator declares by authentic manner that he maintains it.
