Notarial Acts Under Irish Law — A Complete Guide

Every type of notarial act explained — what they are, when you need them, and how they work.

A “notarial act” is any official function performed by a notary public in their capacity as a public officer. In Ireland, notarial acts encompass a wide range of document authentication and attestation services. This guide explains each type, when it is required, and how the process works in practice.

1. Notarisation of Signatures

The most common notarial act is the notarisation (or attestation) of a signature on a document. This involves the notary:

  • Verifying the identity of the signatory (typically through a passport or other photo identification)
  • Confirming that the signatory understands the document they are signing
  • Witnessing the actual signing of the document
  • Affixing the notarial certificate, seal, and signature
  • Recording the act in the notarial protocol

This is commonly required for international contracts, property transactions abroad, immigration documents, and corporate authorisations for use in foreign jurisdictions.

2. Certification of Copies

A notary can certify that a copy of a document is a true and complete copy of the original. This differs from a simple “certified copy” because the notary's seal and signature give it international recognition. Common examples include certified copies of:

  • Passports and identity documents
  • Academic qualifications and transcripts
  • Birth, marriage, and death certificates
  • Corporate documents (certificates of incorporation, memoranda of association)

3. Attestation of Powers of Attorney

Powers of attorney for use abroad are one of the most important areas of notarial practice. The notary must ensure that the person granting the power (the donor) understands its scope and effect, that they are acting voluntarily, and that the document meets the requirements of both Irish law and the law of the country where it will be used. This is governed in part by the Powers of Attorney Act 1996.

4. Administration of Oaths and Affirmations

A notary public can administer oaths and affirmations for documents intended for international use. While a Commissioner for Oaths can administer oaths for domestic purposes, the notary's seal gives the oath international recognition. This is relevant for:

  • Affidavits for foreign courts or tribunals
  • Sworn declarations for immigration purposes
  • Oaths for use in international arbitration

5. Authentication of Corporate Documents

Businesses frequently require notarisation of corporate documents for use abroad, including:

  • Board resolutions
  • Director and shareholder certificates
  • Company seals and signatures
  • Commercial contracts for foreign counterparties
  • Intellectual property assignments

The notary verifies the authority of the person signing on behalf of the company and confirms the document's execution in accordance with the company's constitution.

6. Notarial Protests

One of the oldest notarial functions is the protest of bills of exchange and promissory notes. Under the Bills of Exchange Act 1882, a notary may formally note and protest a bill that has been dishonoured. While less common in modern practice, this remains a valid notarial act under Irish law.

7. Preparation of Notarial Certificates

Notaries prepare various certificates for specific purposes, including:

  • Certificates of law: Confirming the position under Irish law on a particular matter (often required by foreign courts or authorities)
  • Certificates of custom: Attesting to established commercial practices
  • Ship's protests: Recording damage to vessels or cargo (a maritime notarial function)

8. Authentication of Translations

While notaries do not generally act as translators, they can authenticate translations by certifying that a translation has been made by a competent translator and that it accurately represents the original document.

The Notarial Protocol

Every notarial act must be recorded in the notary's protocol — a permanent register that serves as the official record of all notarial functions performed. The protocol includes details of the parties, the documents involved, the type of notarial act, and the date. It must be preserved during the notary's lifetime and surrendered to the Faculty of Notaries Public upon retirement or death.

Common Law Principles Governing Notarial Acts

Notarial acts in Ireland are governed by several common law principles:

  • Duty of impartiality: The notary must act as an impartial public officer, not as an advocate for either party
  • Duty of diligence: The notary must take reasonable steps to verify identity and ensure understanding
  • Duty of confidentiality: Information obtained during the notarial act must be kept confidential
  • Duty to refuse: The notary must refuse to act if they suspect fraud, coercion, or incapacity

Frequently Asked Questions

What are the main types of notarial acts in Ireland?

Notarisation of signatures, certification of copies, attestation of powers of attorney, administration of oaths, authentication of corporate documents, notarial protests, and preparation of notarial certificates. Most notarial work relates to documents for international use.

Is a notarial act the same as having a document witnessed?

No. A notarial act involves identity verification, capacity confirmation, protocol recording, and the affixing of an official seal and signature. It carries legal presumptions that ordinary witnessing does not.

When is a notarial act required under Irish law?

For domestic transactions, notarisation is rarely required by statute. However, documents for use abroad frequently require notarisation — foreign authorities typically require an Irish notary's seal and signature.
