The notarial function, on the other hand, requires the Consular Officer of the Embassy to perform or assist in:
- the administration of all oaths and affirmations provided for by law and in all matters incident to the notarial office;
- the execution of affidavits, depositions, and other documents requiring an oath;
- the receipt of proof and acknowledgement of all writings relating to commerce and navigation (e.g. bills of sale, bottomries, mortgages, hypothecations of ships, vessels, or boats, letters of attorney, deeds, transfers, and assignments);
- acting as magistrate in the writing of affidavits or depositions and making declarations and certifying to the truth thereof.
The authentication and notarial functions both refer to the process of providing legal effect in the Philippines to documents executed abroad. The principal distinction is in the manner by which the document is executed.
- A Certificate of Authentication is issued if the document was previously signed by an authorized official with the official seal affixed, or notarized by a licensed notary public, and such acts were verified and validated by the relevant office of the Ministry of Foreign Affairs; while
- Notarization by Acknowledgement, Jurat, or Certification is done if the person who signed the document does so in the presence of the Consular Officer, then the document will instead be notarized.
