The Functions of a Commissioner for Oaths

The essential functions of a Commissioner for Oaths are:

  • to make sure that the evidence in question is in written form (the draft affidavit)
  • to establish that the person before him/her has read the draft affidavit and fully understands the contents
  • to require the person to swear that the affidavit is true by raising the appropriate Testament in the right hand and repeating the words of the oath
  • to verify that the affidavit was properly sworn by completing a “jurat” on the affidavit
  • to charge a fee for his/her services.

Rules - Oaths and Affirmations

A person making an oath will be required to swear the oath by raising the New Testament. A person who is Jewish may swear the oath by raising the Old Testament.

It’s important to remember that you may also be required to provide evidence of your identity by the Commissioner particularly if you are having an affadavit verified (but this largely depends on the type of documents that is being verified).

It is useful however to bring a standard form of identification with you on your visit, (a passport, driving licence, social welfare book, student I.D. card, etc.).


The fees a Commissioner for Oaths can charge are given in the Rules of the Superior Courts (Fees payable to Commissioners for Oaths) (SI 616 of 2003). There is a standard fee of €10 euro per signature for verifying statements. If there is an exhibit, for example a marriage certificate, attached to the document that needs to be signed, there is a €2 charge for that. You are advised to check charges in advance.
