What is a Company Power of Attorney?

Summary

  • A company power of attorney (POA) allows a business to appoint an attorney to act on its behalf, which must be executed as a deed to be legally valid.
  • The appointed attorney’s authority can be general or limited to specific transactions, and the company remains liable for actions taken within that authority.
  • Directors should ensure the POA is properly authorised under the company’s constitution and the Corporations Act 2001 (Cth) to avoid disputes over validity.

Tips for Businesses

Review your company constitution before executing a POA to confirm the board has authority to delegate. Specify the attorney’s powers clearly and set an expiry date where possible. Keep a register of active POAs and revoke any that are no longer needed in writing.

A company power of attorney is a written document that lets a company appoint someone, the attorney, to act and sign in its name. Under the Companies Act 2006, a company may appoint an attorney by deed to execute documents on its behalf. The appointment must be in writing, because banks and other third parties will ask for a copy before accepting the attorney’s authority. The document sets the limits of that authority, which can be narrow, such as approving invoices, or general, covering wider financial decisions. Companies use them to cover planned absences and sudden illness. This article will outline what a company’s power of attorney is and how you can make use of it for your business.

How Does a Company’s Power of Attorney Work?

A company’s power of attorney is a legal document, alternatively known as a corporate power of attorney. Whichever name you use, you can put it in place to allow another person, called the ‘attorney’, to act on the company’s behalf when you are unavailable.

A company attorney must be appointed in writing because when interacting with other parties, such as other businesses or a bank, the attorney must prove they have the power of attorney. 

The attorney acts in the company’s name and signs documents indicating they are acting under the power of attorney

Requirements for Valid Power of Attorney

Creating a valid company power of attorney requires specific legal formalities to ensure enforceability. The document, in the form of a deed,  must clearly identify both the principal (company) and the appointed attorney, including full names and addresses. 

You must clearly define the scope of the authority. Whether it is limited to specific transactions or gives broader decision-making powers, you should set out how long the authority will last. It is important that there is also a provision in the document allowing the company to revoke the power at any time.

Moreover, the document should be signed by the principal in the presence of witnesses. Some financial institutions may require documents to be certified.

What is the difference between a delegated authority? 

A delegated authority refers to authority granted through the company’s articles of association and board resolutions made pursuant to the articles. Key features include:

  • the articles set out the constitutional framework for who can bind the company;
  • directors typically have the authority to delegate their powers (if the articles permit);
  • usually involves board resolutions authorising specific individuals or setting approval limits
  • less formal than a power of attorney since it does not require execution as a deed;
  • often used for day-to-day operational matters (e.g., signing certain contracts below certain values); and
  • the person acts as an authorised representative rather than as an attorney.

In practice, powers of attorney are used for significant one-off transactions (like property sales), whilst delegated authority handles routine business operations.

Choosing the Right Attorney for Your Business

Selecting an appropriate attorney is crucial for protecting your business interests. Consider appointing someone with relevant business experience who understands your industry and company operations. The attorney should be: 

  • trustworthy; 
  • reliable; and 
  • capable of making sound commercial decisions under pressure.

You may choose to appoint multiple attorneys to act jointly for important decisions, providing additional safeguards against poor judgment.

Alternatively, successive attorneys can be named in case your primary choice becomes unavailable. Professional advisors, such as solicitors or accountants, can serve as attorneys, though this typically involves additional costs for their services.

Key Statistics

  1. 4.87 million: Nearly 4.87 million active UK companies existed as at 31 March 2025, many relying on company powers of attorney for seamless deed execution and business continuity.
  2. 4.4 million: HM Land Registry processed 4.4 million applications in 2024/25, frequently requiring company powers of attorney for valid registered land transactions.
  3. 1,367,053: The Office of the Public Guardian received 1,367,053 power of attorney applications in 2024/25, highlighting sustained demand for robust POA structures in corporate planning.

What Else Could a Company’s Power of Attorney Document Include?

A well-drafted document could also include:

  1. the ability to pay the attorney for their period assisting your company during your absence;
  2. that the attorney has the power to appoint a substitute in the event that they are not available, provided they are liable for the acts of the substitute; and
  3. confirmation that the company will ‘indemnify’ the attorney for certain loss and harm, provided that they are acting within the bounds of their authority – acts of negligence or fraud would not be covered.

“A company power of attorney is only as useful as the third parties who accept it. Banks, landlords and suppliers will want to see the signed document, and some will take days to process it, not hours. Get copies to them while the arrangement is still theoretical, rather than on the morning you need someone to act.”

Frequently Asked Questions

How long does a company power of attorney last?

You can set the duration when creating the document to match your specific needs. It can be set temporarily to cover a fixed period, such as a planned holiday or sabbatical, or it can run until you revoke it. Specify the timeframe clearly in the written agreement. You can cancel the power of attorney at any time by giving written notice to your attorney and to any third parties who hold copies.

Can I have more than one attorney for my company?

Yes, you can appoint multiple attorneys to act on behalf of your company, provided there are no restrictions in the articles of association. Specify in the power of attorney document whether they can act jointly, meaning all attorneys must agree on decisions together, or severally, meaning each attorney can act independently. Joint authority gives you more control but can be impractical when decisions are needed quickly. Several authority offers flexibility but requires careful selection of trusted individuals.

Does a company power of attorney need to be executed as a deed?

Yes. A company power of attorney must be executed as a deed to be legally valid. A company can execute a deed using two authorised signatories, such as two directors, or one director signing in front of a witness who attests the signature.

What happens if my company does not have a power of attorney in place?

Your business becomes vulnerable, because nobody can make or authorise significant decisions while you are unavailable. The company can apply to the Court of Protection to appoint a deputy, but that process is time-consuming and expensive, and the deputy may not be someone you trust.
