Authenticating documents

Foreign governments and organisations sometimes require that documents be authenticated before they accept them. In the Department of Foreign Affairs and Trade, we can authenticate documents that were created in Ireland and legalise documents that were created abroad so that they are acceptable for use in Ireland.

In order to obtain a certification of your Irish birth certificate for use in applying for a California driving license, please submit your original birth certificate, your original passport, and two passport photographs by mail or in person to 100 Pine Street, Ste. 3350, San Francisco, CA 94111 with a cover note detailing your need for a certified copy of your birth certificate.

Information on how to apply for a driving license under AB 60.

Authenticating Documents

  • Overview
  • Methods
  • Documents
  • How to apply



Authenticating a document verifies its origin by confirming that a signature, seal or stamp appearing on a document is genuine.

All documents to be authenticated should bear an original signature, seal or stamp from an Irish practising public official or organisation.

When would I need a document authenticated?

If you are going to use Irish documents overseas, for business or personal reasons, you may be asked to have them authenticated by the Department of Foreign Affairs and Trade.

If you're an Irish citizen returning to Ireland or a foreign national who wants to work or live in Ireland, you may be asked by the Irish authorities to have your documents authenticated by our Embassy staff.

Who can authenticate documents?

In Ireland

The Department of Foreign Affairs and Trade can authenticate documents created in Ireland that will be used in other countries. All documents must show an Irish connection such as an Irish address where the person swearing the document is resident in Ireland.


Staff in our Embassies, Consulates and Honorary Consulates overseas can legalise documents created abroad so that they are acceptable for use in Ireland.

Our Embassy staff is also empowered under Irish law to administer oaths, affirmations and statutory declarations.

They can also certify copies of original Irish documents or translations. Be sure to check that photocopies are acceptable to the authorities you’re dealing with.


Authenticating a document doesn’t mean that its contents are accurate or that we approve of its contents.



How we authenticate documents

The three most common type of authentication are:


Authenticating a document means verifying that the signature, stamp or seal is genuine.


Issuing an apostille is another method of authenticating a document, which may be required by countries that have acceded to the Hague Convention. It involves adding a certificate, either stamped on the document itself or attached to it.


Legalising a document means authenticating the signature or seal of a foreign authority or functionary so that it's acceptable to an Irish court.


Find out what kind of authentication you need from the authorities you're dealing with.



Documents we authenticate

  • Original certificates (eg birth, marriage, death)
  • Company documents issued by the Companies Registration Office
  • Documents signed by the Chambers of Commerce in Ireland
  • Court documents, powers of attorney, and other notarial acts
  • Educational certificates and qualifications recognised by the Department of Education
  • Medical reports signed by a doctor who is registered with the Medical Council of Ireland
  • Garda Clearance letters (they must be issued from the Superintendent's Office of the Garda station where you last lived in Ireland and bear an original stamp and signature of the Garda Siochána).


We can Authenticate\Apostille photocopies of certain types of documents provided they have been certified by a practising Irish Solicitor or Notary Public in Ireland. However, you should in the first instance confirm with the authority to whom you are presenting the document that a certified copy will be acceptable to them.
