A state that has not signed the agreement must indicate how foreign legal documents can be authenticated for its use. Two countries may have a specific convention on the recognition of the other`s public documents, but in practice this is rare. Otherwise, the document must be authenticated by the Foreign Ministry of the country where the document was developed, and then by the Ministry of Foreign Affairs of the State Government where the document is used; one of the certifications is often carried out in an embassy or consulate. In practice, this means that the document must be certified twice before producing legal effects in the recipient country. For example, because Canada is not a signatory, Canadian documents for use abroad must be certified by the Deputy Minister of Foreign Affairs in Ottawa or by a Canadian consular official abroad, and then by the government office or the relevant consulate of the host state.

The Hague Convention for the Abolition of the Legalization of Foreign Public Documents, the Apostille Convention or the Apostille Treaty is an international treaty drawn up by the Hague Conference on Private International Law. It sets out the terms by which a document issued in one of the signatory countries can be certified for legal purposes in all other signatory states. A certification according to the provisions of the Convention is called Apostille (from the Latin post illa, then French: a marginal note) or Apostille from The Hague.  This is an international certification comparable to a certification in national law and generally completes a local certification of the document.
