An Apostille is a certificate issued by the Department of Foreign Affairs and Trade verifying the genuineness of the signature and/or seal of a public officer, on a public document. An Apostille may be required if you wish to use an Irish document in a country which has acceded to the Hague Convention of 5 October 1961 Abolishing the Requirement of Legalisation for Foreign Public Documents.
An Apostille is a certification that validates, on an international level, the authenticity of any public deed, and in particular of a notarial deed. This Legal Institution, recognised by the Countries that have signed the Hague Convention of 5 October 1961, ensures its full validation. For those Countries that have not signed this Convention, a similar stamp is applied. Such procedure is also called Legalisation.
