6 Authorization Letter Samples to Act on Behalf of Someone

An authorization letter to act on behalf is a formal document that grants someone else (an agent or attorney-in-fact) the authority to perform certain tasks or actions on behalf of an individual (the principal).

This letter is alternatively referred to as a letter of authorization or power of attorney. It is used to define the scope and limitations of the transferred legal authority. This is often necessary when you cannot personally attend to certain matters due to reasons such as physical absence, medical conditions, or other commitments. 

In this article, you will learn about instances where you can use a letter of authorization to appoint someone to make decisions or take action on your behalf. You will also gain insights into the different elements of such a letter to ensure that your authority is effectively conveyed to the authorized party as you intend. 

Instances Where Authorization to Act on Behalf Prove Indispensable

An authorization letter can be used in different situations where you require someone to act on your behalf or represent you. This letter may thus be issued for legal, financial, medical, or administrative purposes.

Some common situations where an authority letter might be needed include:

You may need to authorize someone to represent you in legal proceedings. This could involve appointing an agent to sign legal documents, engage legal authorities, or make decisions related to legal matters. This appointment ensures that your interests are protected during the legal proceedings. 

Medical decision making

In case of a medical emergency or incapacitation, you might authorize a family member or trusted individual to make medical choices on your behalf. The letter ensures that proper medical decisions can be made in accordance with your wishes. 

Business transactions

If you are a business owner, you will likely not be physically available for each transaction. Therefore, you can use this letter to authorize an employee or partner to sign contracts, make business decisions, or conduct transactions on your behalf. This ensures the timely completion of transactions and proper representation in situations where your physical presence is not feasible.

      7 Basic Elements of an Authorization Letter to Act on Behalf

      An authorization letter should be clear and precise in detailing the tasks, limits, and timeframes for which the authorization remains effective. To achieve this, the letter typically includes the following key elements to ensure clarity, legality, and accuracy.

      Identification of the parties

      The letter should begin with an accurate identification of the principal (you, the person granting the authorization) and the authorized person (the individual or entity receiving the authority). For both parties, provide the name, contact information, and other identification information such as IDs, employee numbers, or passport details. Ensure that these details align accurately with those found in legal and official documents.

      Statement of authorization

      This is the section where you explicitly grant the authorized person the authority to perform certain actions on your behalf. Accomplish this by specifying the roles of each party in the arrangement and the scope of the authority. Define the scope by enlisting tasks or decisions the agent is permitted to undertake. If there are any actions that the authorized individual must refrain from, clearly stipulate these limitations. The language in this section should be clear, concise, and unambiguous.

      Duration of authorization

      Indicate the time frame during which the authorization remains valid. This could be a specific date range or an open-ended/ongoing authorization. The authority can also be designated for single-use only. Defining a period of validity prevents the misuse of the authority entrusted to the agent. 

      Revocation clause

      Within this section, enlist the circumstances under which the authorization can be revoked or terminated. Additionally, details the revocation process itself. Specify that the revocation must be documented in writing, along with the notice period in terms of days, and the preferred mode of communication. This clause ensures that you retain control of how long the agent holds the authority. 

      Notarization or witnessing

      Depending on the legal requirements or the nature of the authorization, it might be necessary to have the letter notarized by a public notary or witnessed by one or more neutral third parties. This inclusion enhances the credibility and authenticity of the authorization. However, the notary public or witness(es) must sign the letter.  

      Contact information

      Provide up-to-date contact information for both you and the agent. This information allows third parties to reach out for any clarification or communication.

      Any specific requirements

      Lastly, the letter should communicate any specific guidelines or prerequisites needed to complete and exercise the authority. Additionally, relay any directives stipulated by the organization or institution where the authorization will be utilized. These instructions serve as documentation for activities or instances wherein your approval is mandatory before the agent can proceed with a task or decision.

      These authorization letters are effective samples because they clearly and concisely communicate the intent, the authorized individual, and the specific permissions granted. Each letter begins with a direct address to the intended recipient, providing a professional and formal tone right from the start. The use of the subject line offers an immediate understanding of the letter’s purpose, aiding in quick recognition and appropriate handling by the recipient.

      The body of each letter specifies the authorizer’s details, the authorized person’s name and identification number, and the exact scope of the authorization. This precision ensures there’s no ambiguity about what the authorized individual is permitted to do, enhancing the letter’s effectiveness and reducing the risk of misunderstandings.

      Additionally, both samples include a notarization block, which adds legal acknowledgment to the actions being authorized. The notary public’s signature and seal validate the identity of the person granting authorization and their acceptance of the letter’s contents, providing an added level of security and trust to the transaction or representation being authorized.

      Finally, the inclusion of contact information invites further communication if clarification or additional information is needed, showing a willingness to ensure everything proceeds smoothly. This approach underscores the authorizer’s responsibility and care in facilitating the authorized actions, contributing to the overall effectiveness of these letters as tools for granting permissions in a formal, recognized manner.

      Types of Authorization Letters to Act on Behalf

      Authorization letters allowing an individual to act on your behalf can cover a wide range of situations and responsibilities. Regardless of the circumstances, the letter’s purpose remains constant – to grant authority to the agent to act on the principal’s behalf. 

      Below are some common types of authorization letters that you can write:

      Authorization letter on behalf of a company

      This letter of authorization is used to confer authority to a designated individual, typically a company executive or manager. It allows them to undertake predefined actions, negotiate contractual terms, and represent the corporate entity in transactions and engagements.

      Authorization letter to sell property 

      With this letter, the property owner (principal) awards a designated agent (authorized person) with the fiduciary power to execute property sale transactions. Typically, the agent is permitted to initiate negotiations, market, negotiate, execute sale agreements, convey title, and perform requisite documentation, representing the principal’s interests by property sale guidelines and laws. 

      Letter of authority to sign documents on my behalf

      This letter empowers the agent to execute signatures on designated documents for the principal. It delineates the authorization parameters, ensuring alignment with the principal’s stipulated directives. Such a letter expedites paperwork processing in the principal’s absence.  

      Letter of authority to collect money on my behalf 

      Such a letter explicitly grants the agent to collect payments, debts, or deposits on the principal’s behalf. This letter streamlines the collection of money, especially when the authorizer is unable to do so themself. 

      Power of attorney authorization letter

      This document delegates authority to the attorney-in-fact to execute binding legal acts and decisions on your behalf. Such a letter is often used in legal and financial matters. Additionally, it can be applied for general purposes or limited to specific tasks or duration. 

      Letter of authority from the property owner

      A property owner can use this type of letter of authority to allow a second party to access and perform certain tasks within the premises. Such a letter is needed for activities such as maintenance, repairs, or other authorized uses. 

      Frequently Asked Questions

      What is an authorization letter?

      It is a letter that legally permits someone to take necessary action on behalf of someone else.

      When is an authorization letter needed?

      This letter usually comes in handy when someone cannot or is unwilling to partake in certain things by themselves, thereby choosing to delegate the task to others.

      Is an authorization letter a legally binding document?

      In most cases, the appropriate answer would be YES. The reason is that the person signing the letter willingly did so without being forced. Therefore, they have to abide by it.

      Does an authorization letter need to be attested?

      Such a letter does not necessarily need to be attested. However, if the authorized person’s actions carry huge risks, it is crucial to attest to the letter with a notary. At least two people should witness the authorization.

      Final Thoughts

      An authorization letter enables you to entrust a reliable individual or entity with the responsibility for specific tasks or decisions within various legal, financial, and medical contexts. This ensures that your wishes are upheld and decisions are made in your best interests. The agent’s actions are recognized as legally binding upon authentication of the principal’s intent. Therefore, it is essential to meticulously outline the authorization’s scope, duration, and limitations while also adhering to property laws and contractual obligations. Ultimately, strict adherence to existing legal procedures, jurisdictional norms, and applicable standards is crucial during the drafting and execution of such documentation.
