1. Lack of parental consent in certain cases. If a party is 18 years or over, but below 21, and the marriage was solemnized without the consent of the parents/guardian. However, the marriage is validated if, upon reaching 21, the spouses freely cohabited with the other and both lived together as husband and wife.
4. Force, intimidation or undue influence. If the consent of either party was obtained by any of these means, except in cases wherein the force, intimidation or undue influence having disappeared or ceased, the complaining party thereafter freely cohabited with the other as husband and wife.
