An Apostille Certificate is a document that authenticates the origin of a public document. It is issued by a country that is party to the Apostille Convention to be used in another country which is also a party to the Convention.
After authentication (Apostillization) by DFA-OCA as Competent Authority, there is no more need for authentication (legalization) by the Embassies or Consulates except for non-Apostille countries and those that objected to the Philippine accession.
