What Is a Letter of Authorization Form?

Copy section link

A letter of authorization that is also frequently referred as an authorization letter gives someone legal permission to act for you when you're unable to do it yourself. You can use it for tasks related to money, healthcare, or property management. It explains what the person you choose — called an "agent" — is allowed to do on your behalf.

When Do You Need an Authorization Letter?

Copy section link

An authorization letter can be helpful in many situations. In particular, you may need it for:

  • Document collection

    • Picking up documents (e.g., passports, birth certificates, bank statements).
    • Receiving confidential medical records from a hospital or clinic.

  • Medical decisions for minors

    • Allowing a guardian to make medical decisions for your child in your absence.
    • Granting permission for a caregiver to take your child to a doctor.

  • Financial transactions

    • Authorizing someone to handle banking matters (e.g., money withdrawal, check signing).
    • Granting a family member the right to use your credit card.

  • Business-related deals

    • Allowing an employee to sign documents on behalf of the company.
    • Granting access to confidential files or making purchases for business needs.

  • Legal matters and property management

    • Permitting someone to manage your real estate affairs while you’re away.
    • Authorizing another party to collect legal documents from a courthouse.

A letter of authorization form ensures that the appointed person can act legally on your behalf and that institutions or third parties recognize their authority.

Step 1: Fill in the sender’s information

This section identifies you as the person granting authorization.

Part of the authorization letter template
  • Write your full name at the top.
  • Add a complete residential address (city, state, zip code).
  • Include your contact details (email, phone number).
Example:

From: Jessica Carter
Address: 125 Oak Street, Anchorage, Alaska, 99501
Contact information: [email protected], (907) 555-7890

Step 2: Enter the recipient’s information (authorized person or organization)

Appoint an agent and provide instructions on how to contact them.

Part of the letter of authorization example
  • Write the full name of the agent.
  • Provide their complete address.
  • Include contact details (email, phone number).
Example:
  • To: Daniel Roberts
  • Address: 300 Elm Avenue, Birmingham, Alabama, 35203
  • Contact information: [email protected], (205) 555-4567

Step 3: Write the authorization statement

Explain what the agent can and cannot do.

Part of the authorization letter
  • Describe the specific tasks the agent is allowed to do.
  • Specify how long the authorization is valid.
Example:

I, Jessica Carter, residing at 125 Oak Street, Anchorage, Alaska, 99501, hereby authorize Daniel Roberts, residing at 300 Elm Avenue, Birmingham, Alabama, 35203 (the "Representative") to act on my behalf for the purpose of collecting my legal documents from the city office.

This authorization is effective immediately and shall remain in force until I give further notice.

Step 4: Sign and date the authorization letter

A signature is required to make the authorization legally binding.

Example:

Sincerely,

Jessica Carter
Date: April 5, 2025

  • Sign the document with Loio Sign.
  • Hand-deliver or email the letter to the agent and other related people or organizations.
  • Keep a copy of the document.

Can an authorization letter be handwritten?

The document is valid if it includes all required details and signatures. However, a typed letter is easier to read and more likely to be accepted by banks and government offices. With a template, you can create the document in minutes and keep a copy ready whenever you need it.

Common Mistakes to Avoid When Creating a Letter of Authorization

Copy section link

The document has a simple format. However, while drafting it, people often make a few common mistakes.

  • Leave out key details such as names, dates, or tasks.

  • Use vague language.

  • Forget to add signatures.

  • Authorize people whom they do not trust.

  • Fail to check all supporting documents for accuracy.

Even a minor mistake can lead to delays, rejection, or misuse. Review the letter carefully before submitting it. Use a letter of authorization example to make sure you've included all the necessary details.

Legal Considerations for a Letter of Authorization

Copy section link

Double-check the letter for accuracy. Keep these points in mind:

  • Identity documents

    Include a copy of an ID (driver's license or passport). 

  • Verification

    The institution receiving your letter must confirm your identity. 

  • Consent for financial matters

    If someone will handle your money or make financial decisions for you, your written permission is required. A bank statement can back up your financial status.

  • Authorizing someone for a child

    If you give someone authority over a child, attach a birth certificate. 

  • Medical authorization

    If a caregiver will make medical decisions, include medical records. Hospitals also need a signed medical consent form.

How do I write a letter on behalf of someone else?

  1. State for whom you're writing the letter.

  2. Explain your relationship and reason.

  3. Include your name and identity details along with theirs.

  4. Verify that both parties have signed the letter.

  5. Attach all necessary support documents.

Make sure you have the person's full consent. Without it, the letter of authorization form will not be legally valid.
