Authentication of documents
If you wish to use an Irish document overseas, for business or personal reasons, you may need to 'authenticate' or 'Apostille' that document. This is sometimes known as ‘legalisation’. Legalisation simply confirms that a signature, seal or stamp is genuine. Apostille and authentication stamps enable public documents issued in Ireland to be recognised in another country.
The Department of Foreign Affairs and Trade holds records of various signatures, seals and stamps on file, and is the competent authority who confirm they are genuine. The type of stamp issued will depend on what country you will be using the document, and staff in the section will advise this for you.
Our offices on Mount Street, Dublin and South Mall, Cork issue a physical stamp on your documents. We currently do not offer a digital service.
We can only issue Apostille or authentication stamps on Irish public documents. Documents must reference a clear Irish link (for example, an Irish address, Irish Passport details, Irish company registration number).
We cannot advise on whether a document requires authenticating / Apostilling. This is a matter for you to find out. Please contact authorities in the country where the document will be used to check their requirements.
A notary public may be required to notarise your document before we can issue a stamp. For more information, please see The Faculty of Notaries Public in Ireland for information on the Faculty of Notaries and the services of a notary public.
Authenticating / Apostilling a document does not mean that the Department of Foreign Affairs and Trade is verifying the accuracy of the documents or approves of the documents’ contents.
Difference between apostille and authentication
While they accomplish the same objective, there are differences between Apostille and authentication stamps. An Apostille is a certification form set out in The Hague Convention of 5 October 1961 Abolishing the Requirement of Legalisation for Foreign Public Documents, often referred to as The Hague Apostille Convention. An outline of the Hague Apostille Convention can be found at The Hague Conference on Private International Law website.
Where a document needs to be used in a country that is not a signatory to The Hague Apostille Convention, an authentication stamp is issued.
Authentication stamps are a 2-step process, which will require a counter-signature, issued by the Embassy / Consulate of the country where the document will be used. For example, a document for use in a non-Hague country will be authenticated by our office, and must then be presented to the Embassy based in Ireland (or sometimes in the UK) for counter-signing.
The most popular public documents for which Apostilles are issued are civil status documents (e.g., birth, marriage, and death certificates), notarial authentications of signatures, degrees and other education documents.
