Authorisation Letter Format for Various Purposes

Introduction

An authorisation letter is a formal written document. It gives permission to another person to act on your behalf. This permission can be for a specific task or for a limited period. Many people use authorisation letters in daily life. These letters are required in banks, offices, schools, hospitals and government departments. Verbal permission is usually not accepted. Written authorisation is needed for record and verification purposes.

An authorisation letter clearly explains three things. It states who is giving the permission. It mentions who is receiving the permission. It explains what work is allowed to be done. A properly written letter avoids confusion and delays. It also helps prevent misuse of authority. That is why format and clarity are important. This article explains the authorisation letter format for various purposes.

What is an Authorisation Letter

An authorisation letter is a written consent. It allows another person to perform a task on your behalf. The permission is usually limited and specific. The letter works as proof. It shows that the authorised person is acting with approval. Many organisations keep this letter for the record.

Authorisation letters are used for both personal and official work. They are not legal power of attorney documents. They are simpler and used for short-term or specific tasks.

Basic Structure of an Authorisation Letter

The following are the common parts found in every authorisation letter.

Date and Address: This part shows when the letter was written. It also shows where the letter is coming from. It usually includes:

○ Date of writing

○ Sender's full address

○ Receiver's name and address

This helps in record-keeping.

Subject Line: The subject line tells the purpose of the letter. It should be short and clear. Examples include:

○ Authorisation Letter for Document Collection

○ Authorisation Letter for Bank Work

A clear subject helps quick understanding.

Salutation: This is the formal greeting. It is written before the main content. Common options are:

○ Dear Sir/Madam

○ To Whom It May Concern

Formal language is always preferred.

Main Body: This part explains the authorisation in detail. It should be clear and direct. The body usually includes:

○ Name of the person giving authorisation

○ Name of the authorised person

○ Reason for authorisation

○ List for permitted tasks

○ Time period of validity

Avoid unnecessary details.

Closing and Signature: This part confirms the consent. It includes the sender's signature & name. Some letters may also require:

○ Contact number

○ Email address

○ Witness signature

Always sign the letter.

Attachments: This section supports the letter. It helps with identity verification. Common attachments include:

○ ID proof of sender

○ ID proof of authorised person

Some organisations may ask for notarisation.
