Authorization Letter For Bank

Bank transactions are very sensitive, and it is always advisable to complete them yourself. Sometimes, however, circumstances may force you to relegate these duties to another party. This party must be someone you trust and that you can convince your bank to trust. Essentially, you do this by sending an authorization letter for bank expressing your consent. Let’s take a closer look at this letter.

What Is an Authorization Letter for the Bank?

Also called a proxy authorization letter, an authorization letter for the bank is a formal document sent to a financial institution by an account holder consenting to another party to conduct transactions on their account. This party could be a business partner, attorney, friend, or family.

Parties Involved in the Bank Authorization

When it comes to bank authorization, there are three parties involved who are described by the kind of rights they have to act on a bank account. These parties include:

  • First Party: This is the account holder and the one with the most rights to the account. The first party is also the person that gives authorization for their account to be accessed by another party by sending a letter to the second party.
  • Second Party: The second party is the financial institution in charge of the first party’s account. It is usually a bank and the recipient of the first party’s authorization letter with the power to grant the third-party permission to access the account.
  • Third Party: The third party is a group or individual granted access to the first party’s account to conduct transactions on their behalf.

When the authorization is granted, the third party will hold the first party liable for any actions the third party performs on the account during the authorization period.

When to Use a Bank Authorization Letter

There are several situations that may prompt you to grant another party access to your bank account. Common examples include:

  • You want them to fetch your bank statements for you.
  • You want to change or add nominees to your account.
  • You want them to make some payments in your absence.
  • You are temporarily unable to access your account, either due to being ill or out of the country.

How to Write a Bank Authorization Letter

Basically, a bank authorization letter should identify the third party and define the transactions they can complete on behalf of the first party. It should express full and willing consent from the first party, enough to convince the second party to grant the authorizations. Here is how to write it:

Step 1: Identify The Third Party

Write down your name and address at the top of the page, followed by the date and bank’s address. You should always address your authorization letter to the bank manager. Once the addresses are in place, begin your letter by identifying yourself by your full name and account number. Explain that you are writing to grant a third party access to your account and name the third party. You can also explain how you and the third party are related.

Step 2: Define the Responsibilities

Define exactly what kind of access the third party will have to your account, including what they can and cannot do on your behalf. This will ensure the third party does not exceed their rights.

Step 3: Justify the Authorization

Give a reason for why you are giving the authorization to the third party, including why you are unable to complete the transactions yourself. Common reasons include travel, illness, other commitments, etc.

Step 4: Add the Third Party’s Signature

Introduce an identification section for the third party, which the bank will use for verification and reference. Include their full name, identification details, and signature.

Step 5: Define a Validity Period

Set the start and end date for when the authorization will be valid. Leaving the permission open-ended could give the third-party unlimited access to your account.

Step 6: Add the First Party’s Signature

Read everything you have written, confirming it is correct, then sign the letter.
