Semper Praesumitur Pro Matrimonio

means “the law always presume marriage”. Semper = “always”; Praesumitur = presume; pro matrimony = “for marriage”

In Perido vs. Perido, the children of Lucio Perido and Marcelina are presumed to be legitimate and within a valid marriage because the law presumes marriage.

• The testimony of Leonora Perido that she did not witness any wedding even Marcelina picked flowers from her garden cannot rebut this presumption
• Court: “There must be cogent proof to prove illegitimacy of marriage.”
