Discover what a letter of authorisation is and learn how a template can help you streamline the process.
Navigating the different nuances of legal documents is usually daunting for those who are just beginning their career in the field. Among the various types of documents, a letter of authorisation is specifically important because it grants permission or power from one party to another. Read this article to learn more about what a letter of authorisation is, the tips and steps you can follow to write one and the answers to some frequently asked questions.

What is a letter of authorisation?

A letter of authorisation serves as a formal permission tool that delegates authority or power from one party to another. It allows the secondary party to perform crucial actions on the principal party’s behalf. The actions that an individual or an entity can carry out with a letter of authorisation can range from financial transactions to making medical decisions.

Some examples of situations when you can use a letter of authorisation include the following:

  • Financial transactions. If you’re travelling to a different country and would like to designate someone to manage your bank account from your home country, you can issue a letter of authorisation to an individual you trust, like your spouse. This letter of authorisation will enable that person to handle bank withdrawals, deposits and other permissions of your choice.
  • Medical decisions. If you were going to undergo medical surgery, you could write a letter of authorisation to authorise your spouse to make medical decisions on your behalf. These decisions can include surgical procedures or other treatments that your doctor may recommend.

A letter of authorisation is only one example of official documents in the legal field. Letters of intent and affidavits also serve unique purposes in formal proceedings:

  • A letter of intent is usually the first step in formalising the negotiation process before two parties enter into a binding agreement. It’s different from a letter of authorisation because it doesn’t grant permission to act on someone’s behalf, but it outlines an understanding between parties looking to engage in a contract.
  • An affidavit, on the other hand, is a binding document used in legal proceedings that serves to present evidence or verify information under oath.

Formal documents, including a letter of authorisation, require clear and specific information that must be understood by all parties involved. Starting with a template can help to ensure all the necessary details are in place.

5 steps to write a letter of authorisation.

No matter why you need to use a letter of authorisation — managing financial accounts, making medical decisions or handling properties — this document is the perfect tool you’ll want to use to make your processes easier. However, writing a clear and concise letter can be challenging if you’re unfamiliar with it and unsure about where to start. Here are five steps you can follow to craft one effectively.

1. Identify the parties involved.

Start by stating your name and address along with the name, address and other relevant information of the individual you’re authorising. This identification at the start of your letter sets a great foundation for the agreement as it clarifies who is involved and under what capacity.

2. Specify the authority granted.

Detail the specific actions the authorised person can perform. Try to be as clear and meticulous as possible to avoid confusion or ambiguity.

3. Define the duration of the agreement.

Include the start and end dates for the authorisation. This step is important to ensure that the authority isn’t open-ended. If the authorisation is for a single transaction, mention that explicitly.

4. Include any necessary details.

You might need to include additional information for the arrangement to be effective, but this step depends on the nature of the authorisation. For example, this could be account numbers, specific conditions under which they can act or limitations to the authority you grant the authorised individual.

5. Sign the document.

Lastly, both the person granting the authorisation and the authorised individual should sign the document. It’s also often important to have the signatures notarised to add an extra layer of validity, especially if you need to authorise more significant transactions.
