TL;DR: A Power of Attorney authorises another person or entity to act on your behalf. For business use, a well-drafted POA can be essential when you are unavailable or in multi-country operations.

What You Need to Know

A Power of Attorney (POA) is a legal document that authorises one person or entity (the "attorney" or "agent") to act on behalf of another (the "principal") in specified matters. In a business context, POAs are used frequently:

The POA is a powerful document — the attorney can bind the principal in whatever matters fall within the scope of the POA. A poorly drafted or overly broad POA can expose the principal to significant risk. Equally, a POA that is too narrow may not give the attorney the authority needed to fulfil their purpose.

How It Works: A Practical Overview

Types of Power of Attorney

General Power of Attorney: Grants broad authority to the attorney to act across all (or most) matters on behalf of the principal. Typically used for a defined period or for a specific purpose such as managing affairs while the principal is overseas.

Special/Specific Power of Attorney: Grants authority to act in one specific matter — for example, to sign a particular contract, sell a specific property, or represent the principal at a single transaction. The scope is limited to the identified matter.

Irrevocable Power of Attorney: Cannot be revoked by the principal for a defined period. Used where the attorney needs certainty of authority — for example, a lender holding security over assets. Irrevocable POAs are subject to specific legal requirements that vary by jurisdiction.

Enduring/Durable Power of Attorney: Remains valid even if the principal becomes mentally incapacitated. Primarily used in personal rather than business contexts, though relevant for sole traders and business owners who want continuity of management in the event of incapacity.

Key Elements of a Business POA

A valid business POA must typically contain:

Identity of parties: Full legal names and addresses of the principal and attorney.

Scope of authority: A clear, specific description of what the attorney is authorised to do. For business POAs, this should be drafted with sufficient precision to enable the attorney to act, while limiting authority to what is genuinely needed.

Duration: The period during which the POA is valid, or a statement that it is valid until revoked.

Revocation: How and when the POA can be revoked.

Execution requirements: The witnessing, notarisation, or apostille requirements applicable in the relevant jurisdiction.

Company POA: When a company (rather than an individual) grants a POA, the authorisation must come from the company's board of directors and be executed in accordance with the company's articles/constitution. The attorney acts as agent for the company.

Execution and Formality Requirements

The formal requirements for a valid POA vary significantly by jurisdiction:

Always check the specific requirements of both the country where the POA is executed and the country where it will be used.

Revoking a Power of Attorney

A POA can generally be revoked by the principal at any time (unless it is irrevocable). To revoke a POA:

Third parties who act in good faith in reliance on a POA before receiving notice of revocation may be protected.

Common Mistakes to Avoid

  1. Granting overly broad authority. A general POA that is not limited in scope can authorise the attorney to do anything the principal could do — including taking on debts, selling assets, or making gifts. Be specific about what authority is granted.
  2. Not notarising or obtaining an apostille when required. A POA that has not been properly authenticated may be rejected by banks, registries, or counterparties. Check the requirements of every jurisdiction and institution where the POA will be used before executing it.
  3. Forgetting to revoke a POA when it is no longer needed. An unrevoced POA remains valid and potentially usable until its expiry. If circumstances change (the attorney leaves the business, the transaction is completed), revoke the POA promptly.
  4. Using a personal POA for company matters. A POA granted by an individual director to act on their personal behalf does not authorise them to bind the company. Company authority comes from a board resolution or company-level POA.
  5. Not checking whether the attorney is eligible. Attorneys must typically be adults with legal capacity. In some contexts, attorneys may be subject to regulatory requirements (for example, attorneys acting in financial transactions may need to be authorised by a financial regulator).

Frequently Asked Questions

Q: Can a company grant a Power of Attorney?

A: Yes. Companies frequently grant POAs to authorise employees, agents, or external representatives to act on their behalf. The POA must be authorised by the company's board of directors (documented in board minutes) and executed in accordance with the company's constitution and applicable company law — typically by two directors or a director and company secretary (in the UK, for example).

Q: What is the difference between a Power of Attorney and a company signatory authorisation?

A: A company signatory authorisation (often set out in board minutes or a "banking mandate") authorises specific individuals to sign specific types of documents on behalf of the company. A POA is a more formal document that grants a specific (and often broader) range of authority to an external party. Both are mechanisms for authorising someone to act on behalf of the company, but the appropriate mechanism depends on the specific context.

Q: Does a Power of Attorney expire automatically?

A: It depends on the terms of the POA. Some POAs specify an expiry date; others remain valid until revoked. General POAs typically do not expire unless specifically limited. However, the POA may terminate automatically if: the principal dies (though certain transactions may be protected if done in good faith before notice of death); the principal becomes bankrupt (in some jurisdictions); or — for non-enduring POAs — the principal loses mental capacity.
