Unnatural Will is a will that distributes the testator’s estates to strangers rather than to the testator’s relatives without any apparent reason. In civil law these types of wills are referred to as Undutiful Wills. On the other hand a Will that disposes of property to the testator’s family is called an Officious will. In these types of Wills the estate or property under the Will is reserved for the testator’s children and other natural heirs.
