## What is a Letter of Authority?

A Letter of Authority lets you formally authorize someone else to act on your behalf in Ireland. It's commonly used when you need a representative to handle specific tasks - from managing your accounts to dealing with government agencies like Revenue or accessing your medical records.

You'll need to clearly state what powers you're granting, specify both parties' details, and sign the document. While simpler than a Power of Attorney, it still carries legal weight under Irish law. Many Irish businesses and organizations require these letters before they'll discuss your affairs with your chosen representative, especially for financial or healthcare matters.

## When should you use a Letter of Authority?

Use a Letter of Authority when you need someone to handle specific matters on your behalf in Ireland but don't require the extensive powers of a Power of Attorney. Common situations include authorizing a family member to discuss your tax affairs with Revenue, letting an accountant manage your business dealings, or enabling a trusted friend to access your medical information while you're abroad.

The letter proves especially valuable during temporary absences, busy periods, or when dealing with multiple Irish institutions simultaneously. It gives your representative clear, limited authority to act - perfect for time-sensitive tasks or ongoing administrative needs where you remain the primary decision-maker but need help managing day-to-day matters.

## What's the difference between a Letter of Authority and a Certificate of Authority?

A Letter of Authority is often confused with a [Certificate of Authority](https://www.genieai.co/en-ie/template-type/certificate-of-authority), but they serve distinctly different purposes in Irish law. While both relate to authorization, their scope, formality, and typical uses vary significantly.

- **Legal Weight**: Letters of Authority are typically informal documents for specific, limited tasks, while Certificates of Authority are formal legal instruments often issued by government bodies or regulatory authorities
- **Duration**: Letters usually cover temporary or specific actions, while Certificates generally provide ongoing authorization for business operations
- **Purpose**: Letters delegate personal or business tasks to a representative, while Certificates prove an entity's legal right to conduct business in Ireland
- **Requirements**: Letters need basic identification and signatures, while Certificates often require extensive documentation, regulatory compliance, and official verification
- **Revocation**: Letters can be easily cancelled by the grantor, while Certificates require formal procedures for modification or cancellation
