Whether you are dealing with property abroad, immigration applications, company documentation, or sworn legal paperwork, you may be asked to have documents witnessed, certified, notarised, or sworn before a legal professional. Two services commonly requested are Notary Public services and Commissioner for Oaths services.
While they are sometimes confused, they serve different purposes. This guide explains the difference and outlines how we can assist.
What is a Commissioner for Oaths?
A Commissioner for Oaths is authorised to:
- witness signatures,
- administer oaths and affirmations,
- and certify statutory declarations and affidavits.
These services are commonly required for:
- court documents,
- probate matters,
- family law proceedings,
- statutory declarations,
- and various legal forms.
When attending an appointment, you will generally need:
- valid photographic identification,
- and the unsigned document requiring witnessing.
It is important that documents are not signed in advance unless specifically advised to do so.
What is a Notary Public?
A Notary Public is a qualified legal professional authorised to certify, authenticate, and notarise documents for use internationally.
Notarial services are commonly required where Irish documents are being used overseas or where foreign authorities require formal verification of identity, signatures, or legal documents.
Examples include:
- powers of attorney,
- passport certifications,
- foreign property transactions,
- company and corporate documents,
- immigration and visa applications,
- educational qualifications,
- and travel consent letters.
A notary may also arrange for documents to be apostilled or legalised where required for use in particular countries.

| Typically for Irish legal use | Typically for international use |
| Witnesses affidavits and declarations | Authenticates documents and signatures |
