Is the text of the aforementioned will valid and permissible?

A bequest contingent on the death of the endower is valid and takes the ruling of a will, meaning it is executed within the limits of one-third of the estate. Anything exceeding that is not executed unless the heirs consent. As for a bequest contingent on the death of others after the demise of the testator, some jurists have deemed it impermissible due to the harm it inflicts upon the heirs through prolonged waiting. Therefore, the wording of the bequest should be amended, and consideration should be given to whether the endowed house exceeds one-third of the estate, so that it can be adjusted accordingly.
