Parental consent is needed when either party is between the age of 18 and 21. The pertinent provision of the Family Code reads:
Art. 14. In case either or both of the contracting parties, not having been emancipated by a previous marriage, are between the ages of eighteen and twenty one, they shall, in addition to the requirements of the preceding articles, exhibit to the local civil registrar, the consent to their marriage of their father, mother, surviving parent or guardian, or persons having legal charge of them, in the order mentioned. Such consent shall be manifested in writing by the interested party, who personally appears before the proper local civil registrar, or in the form of an affidavit made in the presence of two witnesses and attested before any official authorized by law to administer oaths. The personal manifestation shall be recorded in both applications for marriage license, and the affidavit, if one is executed instead, shall be attached to said applications.
Parental consent is different from parental advice, which is needed when either party is between the age of 21 and 25.
Certification from Solemnizing Officer
In addition to the separate requirements for parental consent or parental advice, parties who are required to secure either parental consent or parental advice must attach a certificate that they have undergone marriage counselling.
Art. 16. In cases where parental consent or parental advice is needed, the party or parties concerned shall, in addition to the requirements of the preceding articles, attach a certificate issued by a priest, imam or minister authorized to solemnize marriage under Article 7 of this Code or a marriage counsellor duly accredited by the proper government agency to the effect that the contracting parties have undergone marriage counselling. Failure to attach said certificate of marriage counselling shall suspend the issuance of the marriage license for a period of three months from the completion of the publication of the application. Issuance of the marriage license within the prohibited period shall subject the issuing officer to administrative sanctions but shall not affect the validity of the marriage.
Should only one of the contracting parties need parental consent or parental advice, the other party must be present at the counselling referred to in the preceding paragraph.
The issuance of the marriage license within the 3-month period without the certificate of counselling, however, does not affect the validity of the marriage, but only renders the responsible party administratively liable.
