Types of Certifications
  • Apostille - An "apostille" is a form of authentication issued to documents for use in countries that participate in the 1961 Hague Convention. A list of countries that accept apostilles is provided by the Hague Conference on International Law and is available here.
  • Authentication or Certification - If the country of intended use does not participate in the Hague Convention, documents being sent to that country can be "authenticated" or "certified".
