17. Lennon made a last will and testament which contained two simple dispositions, to wit: “First, I am leaving one-half of my estate in favor of the poor…. Second, I am leaving the other half of my estate in favor of my soul….” Lennon named Atty. Manresa as executor and instructed him to carry out the provisions of his will. In 2024, Lennon died single and childless. Thereafter, Lennon’s will was presented for probate. The siblings of Lennon opposed the probate of the will and claimed his entire estate through intestate succession. The siblings of Lennon argued that his testamentary dispositions are void because the first is in favor of an unknown person while the second is for a beneficiary without civil personality. Are the dispositions in Lennon’s will void? Explain.
