A Power of Attorney is a legal document authorising one person to act on behalf of another in specified legal, financial, or business matters, including signing documents and making decisions.

A Power of Attorney (POA) is a legal document through which one person, known as the donor or grantor, authorises another person, known as the attorney or agent, to act on their behalf in specified legal, financial, or business matters. The attorney can sign documents, manage bank accounts, enter contracts, and make decisions within the scope defined by the POA. For Irish businesses, powers of attorney are commonly used when a director or shareholder cannot be physically present to execute a transaction, when a company needs a local representative for specific jurisdictional requirements, or when a founder wishes to delegate authority during an extended absence.
A POA can be general, covering a wide range of acts, or specific, limited to a particular transaction or category of decisions. In a corporate context, specific powers of attorney are more common, as they provide clear boundaries on the agent's authority and reduce the risk of the agent acting beyond what was intended. A general power of attorney, if granted carelessly, can expose the donor to significant financial and legal risk if the attorney makes decisions that the donor would not have sanctioned.
The legal framework for powers of attorney in Ireland is governed by the Powers of Attorney Act 1996 and the Enduring Powers of Attorney Act 2023, which replaced earlier legislation and significantly updated the rules around enduring powers in particular. For purely commercial POAs used in business transactions, the 1996 Act is the primary reference point, while enduring powers, which continue even if the donor becomes incapacitated, are governed by the 2023 regime and are more relevant in a personal rather than corporate context.
In a corporate setting, powers of attorney arise in several common situations. During international transactions, an Irish company may grant a POA to a local lawyer or representative in a foreign jurisdiction to execute documents on its behalf without requiring directors to travel. During property transactions, a POA allows one party to sign completion documents if they cannot be present at the appointed time. During investment rounds and mergers, a POA may be granted to a lead negotiator to execute transaction documents on behalf of multiple parties simultaneously.
Companies also use powers of attorney internally, particularly where a director is travelling, ill, or otherwise unavailable to sign time-sensitive documents. In such cases, the POA grants another director, officer, or trusted individual the authority to act temporarily within defined limits. This is distinct from the normal directors' duties framework, which governs what directors can do by virtue of their appointment rather than by delegation.
To be valid in Ireland, a Power of Attorney must be executed as a deed. This means the document must be signed in the presence of a witness who also signs and dates the document. The witness cannot be the attorney named in the POA or the donor's spouse or civil partner. The document must clearly identify the donor, the attorney, and the scope of the authority being granted.
For use in foreign jurisdictions, additional formalities are often required. Many countries require an apostille, which is a form of international certification under the Hague Convention that verifies the authenticity of the Irish notary's signature. Your solicitor or a notary public can arrange apostille certification through the Department of Foreign Affairs. This process adds time and cost to the execution of an international POA, so planning ahead is important if you have a time-sensitive transaction.
A Power of Attorney can be revoked by the donor at any time, provided they have mental capacity to do so. Revocation must be communicated to the attorney and, where relevant, to third parties who may be relying on the POA to enter transactions with the attorney. If a third party enters a transaction in good faith without knowledge of the revocation, the transaction may still be binding on the donor, so prompt and documented revocation is important.
A standard POA automatically terminates if the donor becomes mentally incapacitated, which is why enduring powers of attorney were developed for situations where continued authority during incapacity is needed. For corporate purposes, most POAs will also specify an end date or tie termination to the completion of a specific transaction, preventing the authority from remaining open-ended and potentially being exercised in ways the donor did not anticipate.
Granting a Power of Attorney is a significant act that should not be done without legal advice. The attorney owes fiduciary duties to the donor and must act in the donor's best interests, within the scope of the authority granted, and without personal profit unless expressly authorised. However, the practical reality is that oversight of an attorney's actions can be difficult, particularly in a commercial setting where transactions move quickly.
Good governance practice dictates that POAs should be specific in scope, time-limited, and granted only to individuals whose trustworthiness has been established. Maintaining clear company records of all powers of attorney granted and revoked, including copies of the executed documents and confirmation of revocation where applicable, is an important part of your corporate compliance obligations. Your company secretary should maintain a register of active powers of attorney and flag upcoming renewals or required revocations as part of routine governance oversight.
