Apostille Convention: The Philippines is a signatory to the Apostille Convention. However, for an apostilled document to be recognized, the underlying document (e.g., a marriage certificate) must first be legally valid according to both the issuing and recognizing countries' laws.
Legal Recognition: Even if an online marriage is legally recognized in another country and duly apostilled, it does not necessarily warrant recognition in the Philippines if it contravenes the basic requirements of Philippine marriage laws.

Legal Advice and Steps to Consider

Consultation: Couples interested in the legality of online marriages should consult with legal experts to explore their options and understand the implications of foreign laws on their marital status in the Philippines.
Legal Compliance: For those residing abroad or with foreign partners, it's advisable to comply with the legal requirements for marriage in the jurisdiction where the couple intends to reside or where the marriage will have legal consequences.

Conclusion

While technology and societal norms evolve, Philippine law currently maintains traditional requirements for marriage to ensure legality and validity. Couples considering online marriage must seek comprehensive legal advice and consider all implications regarding their marital rights and status both in the Philippines and abroad.
