A Irish national intending to marry a Filipino national in the Philippines has to secure a birth certificate and a Certificate de Coutume  from the Department of Foreign Affairs and Trade in Ireland. Then the foreign national has to present these documents to his Embassy/Consulate in the Philippines for him to be issued a Certificate of Legal Capacity to Marry. The said certificate is needed for his application for a marriage license at the registry office of the locality/church where the marriage is to take place.
