3 Conditions of Valid Marriage

The Civil Code 2074's Chapter on Marriage — the conditions by principle (the Code's design):1. Monogamy: neither party having a spouse living (the bigamy bar — the void-and-criminal consequence);2. Minimum age:twenty years for both parties (the 2072 Constitution's era-settlement; the age-20 rule now codified in both the Civil Code and the Children's Act's child definition — marriage below 20 = child marriage);3. Prohibited degrees: no marriage within the prohibited relationship (the sapinda/prohibited- degrees schedule — the incest bar, both by blood and by affinity, with the statutory exception for customary-community practice where recognized);4. Free consent: no coercion, undue influence or fraud (the kidnapped-and-duped marriage invalid);5. No other statutory bars (e.g., the mental-condition requirements where the Code prescribes).Formalities: the marriage performed by ceremony (social marriage) or by registration — and registered (Section 6) for the certificate's evidentiary status; consummation-and-cohabitation as the social (not statutory) completion.
