What Is a Authorisation Letter (Ireland)?
An Authorisation Letter in Ireland gives written permission for a specific act and records the scope and limits of the consent provided.
Authorisation letters in Ireland operate within the general law of agency, which is derived from the common law and supplemented by statute. The general principle is that a principal may authorise an agent to act on their behalf, and the agent's acts within the scope of that authority bind the principal. The agent owes the principal duties of loyalty, care, and obedience, and must act within the limits of the authority granted. If the agent acts outside the scope of their authority, the principal is not bound by those acts — unless the third party dealing with the agent was reasonably entitled to assume the agent had the necessary authority (apparent authority).
An authorisation letter is appropriate for straightforward, limited-scope tasks and is a less formal instrument than a Power of Attorney. A Power of Attorney is a legal instrument formally conferring authority on an attorney-in-fact and, for an Enduring Power of Attorney (EPA), must comply with the formalities of the Assisted Decision-Making (Capacity) Act 2015 — including registration with the Decision Support Service (DSS). An authorisation letter, by contrast, does not require registration or specific legal formalities for most everyday purposes.
Common uses for an authorisation letter in Ireland include: authorising a family member or trusted friend to collect official documents from a government office (such as the Department of Social Protection, Revenue, or the Property Registration Authority); authorising a person to act on your behalf at a one-off meeting, appointment, or transaction; granting permission to a third party to access or receive information held by an institution (subject to GDPR and Data Protection Act requirements); authorising a person to sign for deliveries or parcels on your behalf; or granting limited authority to deal with a specific utility company, insurance company, or service provider.
For banking and financial matters, Irish financial institutions have their own specific requirements for third-party mandates, and a simple letter may not suffice. For medical decisions, the Assisted Decision-Making (Capacity) Act 2015 requires specific statutory instruments. An authorisation letter should always state the scope and duration of the authority clearly to avoid misuse or dispute.
In Irish practice, the scope of authority conferred by an authorisation letter is construed strictly — the authorised person can only do what the letter expressly permits, and the third party dealing with them is entitled to rely on the letter only to the extent of its express terms. Where the authorised person exceeds the scope of their authority, the principal (the authorising party) is not bound by those acts, unless the third party was reasonably entitled to assume the authority existed (the doctrine of apparent or ostensible authority under the common law of agency). It is therefore essential that the authorisation letter is drafted with sufficient precision to cover all the tasks the authorised person needs to perform, without being so broad as to create unintended authority.
When Do You Need a Authorisation Letter (Ireland)?
An Irish Authorisation Letter is needed whenever you wish to formally delegate authority to another person to act on your behalf for a specific purpose, and a simple written letter is sufficient for the third party's requirements.
You need an Authorisation Letter when you are: unable to attend in person to collect documents, attend a government office, or complete a transaction, and wish to send a trusted person on your behalf; authorising a family member, friend, or colleague to deal with a specific organisation (such as a utility company, an insurance provider, or Revenue) on your behalf for a defined purpose; granting a business colleague or employee authority to collect, sign for, or deliver documents on your behalf; authorising a person to access information held about you by a third party (such as a medical record, a government record, or an account statement) in compliance with GDPR consent requirements under Article 6(1)(a) of the General Data Protection Regulation; travelling abroad and wishing to authorise someone to manage a specific task in Ireland in your absence; acting as a company officer and wishing to delegate authority to a specific employee or agent for a defined transaction; or authorising a parent, guardian, or carer to act on behalf of a child or other person in a routine, non-medical context.
An authorisation letter is most appropriate where the scope of authority is limited, the task is specific and time-bound, and the third party to whom the letter is addressed is willing to accept a letter (rather than a formal Power of Attorney or a bespoke mandate). Before preparing an authorisation letter, it is always advisable to check with the relevant institution or organisation what format they will accept — some bodies (including certain banks, court offices, and government departments) require specific forms or a more formal instrument.
For significant or ongoing authority — such as managing all financial affairs, making healthcare decisions, or representing a party in litigation — an Enduring Power of Attorney (EPA) under the Assisted Decision-Making (Capacity) Act 2015, which fully commenced on 26 April 2023, is more appropriate than a simple authorisation letter. EPAs under the 2015 Act must be registered with the Decision Support Service (DSS) to take effect, and the formalities include execution before a solicitor and a registered medical practitioner. For businesses, a formal mandate or board resolution under the Companies Act 2014 is the appropriate instrument for delegating significant corporate authority.
Practically speaking, many Irish government departments and agencies publish their own prescribed forms for authorising a third party to act on a person's behalf. Revenue has specific online agent authorisation procedures through the myAccount and ROS (Revenue Online Service) portals under the Taxes Consolidation Act 1997. The Department of Social Protection has specific consent forms for authorising access to records held under the Social Welfare Acts. The Property Registration Authority (PRA) has its own requirements for third-party authorisation in relation to Land Registry dealings under the Registration of Title Act 1964. Before drafting a general authorisation letter, always check whether the relevant institution has its own prescribed form, as using the correct form reduces the risk of rejection and confirms all required information is included. For use abroad, the authorisation letter may need to be apostilled by the Department of Foreign Affairs under the Hague Apostille Convention 1961, to which Ireland is a contracting state.
Under Irish law, the Data Protection Act 2018 and GDPR Article 6 govern personal data in this document. The Consumer Rights Act 2022 protects individuals in consumer transactions. Section 67 of the Land and Conveyancing Law Reform Act 2009 applies to personal property matters. The Circuit Court and District Court have jurisdiction over personal disputes under the Courts (Supplemental Provisions) Act 1961. The Commissioners of Irish Lights and Revenue Commissioners may have compliance roles depending on the transaction type.
What to Include in Your Authorisation Letter (Ireland)
The scope limitation clause specifies any restrictions on the authority granted — for example, limiting the authorised person to specific acts, specific time periods, or specific monetary limits. A clearly limited scope reduces the risk of the authorised person exceeding their authority and protects the principal from unintended liability. The revocation clause specifies how the authorisation can be revoked — typically by written notice to the authorised person and (where the authorisation has been registered or notified to third parties) to those third parties. For authorisations relating to financial transactions or property, the revocation should be made in writing and notified to all relevant third parties as soon as possible. The data protection clause addresses the GDPR implications — confirming that the principal consents to the authorised person collecting and processing personal data on their behalf for the stated purposes, and that any personal data accessed is processed only as necessary and in compliance with the GDPR and the Data Protection Acts 1988 to 2018. The liability clause addresses who bears responsibility if the authorised person acts outside the scope of their authority or causes loss to the principal or third parties through their actions. Under the general law of agency in Ireland, a principal is bound by acts done by an agent within the scope of their actual or apparent authority. The governing law clause confirms that the authorisation letter is governed by Irish law and that disputes are subject to the jurisdiction of the Irish courts. For authorisations intended to be used in other jurisdictions, it may be necessary to have the letter apostilled by the Department of Foreign Affairs in Ireland for use in Hague Convention countries, or legalised through the relevant embassy for countries that are not party to the Hague Apostille Convention.
The scope limitation clause specifies any restrictions on the authority granted — for example, limiting the authorised person to specific acts, specific time periods, or specific monetary limits. A clearly limited scope reduces the risk of the authorised person exceeding their authority and protects the principal from unintended liability. Under the general law of agency in Ireland, a principal is bound by acts done by an agent within the scope of their actual or apparent authority — so limiting the scope in writing is an important protection. The revocation clause specifies how the authorisation can be revoked — typically by written notice to the authorised person and (where the authorisation has been notified to third parties) to those third parties as well. The data protection clause addresses the GDPR implications — confirming that any personal data accessed by the authorised person on the principal's behalf is processed only as necessary and in compliance with the GDPR and the Data Protection Acts 1988 to 2018. The liability clause addresses who bears responsibility if the authorised person acts outside the scope of their authority or causes loss to the principal or third parties. The governing law clause confirms that the authorisation letter is governed by Irish law and that disputes are subject to the jurisdiction of the Irish courts. For authorisations intended to be used in other jurisdictions, it may be necessary to have the letter apostilled by the Department of Foreign Affairs in Ireland for use in Hague Convention countries.

Frequently Asked Questions
An authorisation letter in Ireland is a written document in which one person (the principal or authorising party) grants another person (the agent or authorised person) the authority to act on their behalf for a specific purpose and within defined limits. It is a simple, informal form of agency — granting the authorised person the right to represent the principal in relation to a specific transaction or set of tasks, without the formality of a Power of Attorney (which requires specific legal formalities under the Assisted Decision-Making (Capacity) Act 2015). An authorisation letter is appropriate for straightforward, limited-scope tasks such as collecting official documents from a government office, signing for a delivery, dealing with a utility company, or acting on a person's behalf at a one-off meeting. It is generally sufficient where the third party (the institution, organisation, or person dealing with the authorised agent) is willing to accept it. Many government bodies in Ireland — including the Department of Social Protection, Revenue (through myAccount or Collector-General correspondence), the Property Registration Authority, and local authorities — will accept a simple authorisation letter for routine transactions, though some require specific forms or more formal instruments such as a Power of Attorney.
Unlike a Power of Attorney (which under the Assisted Decision-Making (Capacity) Act 2015 and its predecessors requires specific formalities including signature by a solicitor or other authorised person), a simple authorisation letter in Ireland does not generally need to be witnessed or notarised to be legally effective between the parties. Under the general law of agency in Ireland (derived from the common law), authority can be conferred orally or in writing, and there is no statutory requirement for an authorisation letter to be witnessed or notarised to be effective. However, in practice, whether a witness or notarisation is required depends on what the authorisation letter is being used for and what the institution or third party accepting it requires. For dealings with Irish government bodies, public offices, or institutions that have their own procedural requirements, it is common for those bodies to require a witnessed or notarised signature on an authorisation letter — particularly where the transaction is significant (for example, collecting a pension payment or making a change to a property title). For international use — for example, where an Irish person wishes to authorise an agent to act on their behalf in a foreign country — the authorisation letter may need to be notarised by a Notary Public in Ireland and apostilled under the Hague Apostille Convention 1961 (to which Ireland is a signatory) for it to be recognised in the country where it is to be used.
A simple authorisation letter is generally not sufficient for medical decisions in Ireland. The Assisted Decision-Making (Capacity) Act 2015 (commenced in full on 26 April 2023) fundamentally reformed the legal framework for decision-making by persons whose capacity may be in question, and created specific legal instruments for healthcare decisions. For medical decisions, the appropriate instrument in Ireland is an Advance Healthcare Directive (AHD) — a written statement by which a person (the directive-maker) sets out their wishes regarding medical treatment in the event they lose capacity to make decisions. An AHD under the 2015 Act can appoint a healthcare representative who has authority to consent to or refuse medical treatment on the directive-maker's behalf when the directive-maker lacks capacity. The 2015 Act also created the concept of a Decision-Making Assistance Agreement, a Co-Decision-Making Agreement, and a Decision-Making Representation Order for persons whose capacity is limited, and these instruments require specific formalities under the Act. For persons who have capacity, an Enduring Power of Attorney (EPA) under the Assisted Decision-Making (Capacity) Act 2015 can include a healthcare component, appointing a designated healthcare representative. A simple authorisation letter is not a substitute for these statutory instruments in medical contexts.
When an authorisation letter is used to grant a third party access to personal data held about the authorising party — for example, authorising a family member to access a bank account, obtain medical records, or collect documents from a government body — the General Data Protection Regulation (GDPR) (Regulation (EU) 2016/679) and the Data Protection Acts 1988 to 2018 are relevant. The organisation holding the personal data is a data controller and must require that it only discloses personal data to authorised recipients. Under Article 5 of the GDPR, personal data must be processed lawfully, fairly, and in a transparent manner and must not be disclosed to unauthorised third parties. An authorisation letter provides evidence that the data subject (the person whose data is involved) has consented to the disclosure of their personal data to the authorised person for the specified purpose. Under Article 6(1)(a) of the GDPR, consent is a valid lawful basis for processing, provided the consent is freely given, specific, informed, and unambiguous. The authorisation letter should therefore clearly specify what information the authorised person is permitted to access, receive, or use — so that the organisation holding the data can assess whether the disclosure is within the scope of the consent. The Data Protection Commission (DPC) recommends that organisations receiving authorisation letters take reasonable steps to verify the identity of both the authorising party and the authorised person before disclosing personal data.
A Authorisation Letter (Ireland) does not legally require a lawyer in Ireland, and individuals and businesses may draft and execute the document independently. The Sale of Goods and Supply of Services Act 1980 does not mandate legal representation for the creation or signing of this type of document. However, seeking independent legal advice from a qualified Ireland lawyer is recommended for transactions involving substantial financial value, complex regulatory requirements, or cross-border elements where multiple legal jurisdictions may apply. A lawyer can verify that the document complies with all applicable statutory requirements, identify potential risks specific to the transaction, and confirm that the terms adequately protect the interests of all parties involved. The High Court of Ireland has jurisdiction over disputes arising from this type of document, and Companies Registration Office (CRO) may impose additional compliance obligations depending on the nature of the underlying transaction. Professional legal review is particularly advisable where the document will be submitted to government agencies or used as evidence in legal proceedings.
