Isabel de La Puerta v. The Honorable Court of Appeals

Summary

This case involved a succession dispute where Carmelita de la Puerta claimed inheritance rights from her alleged grandmother Dominga Revuelta's estate. Lower courts found Carmelita to be the natural child of Vicente de la Puerta (Dominga's son) based on substantial evidence including Vicente's own testimony. However, the Supreme Court reversed, ruling that even if Carmelita was Vicente's spurious child, Article 992 of the Civil Code creates an absolute barrier preventing illegitimate children from inheriting ab intestato from legitimate relatives of their father. Since Vicente survived his mother Dominga, no right of representation existed. The Court emphasized the policy reasons behind this prohibition, noting the presumed antagonism between legitimate and illegitimate families. Carmelita's inheritance claims must be pursued in Vicente's own estate proceedings, not in Dominga's probate. This decision reinforced the Civil Code's strict separation between legitimate and illegitimate families in succession matters.
