What is an Authorization Letter?

An Authorization Letter is a document used for authorizing a person to carry out certain actions on behalf of the person writing the letter.

A letter of authorization can be used when a person is busy and cannot do things on their own, hence authorizing a third person to do the task on their behalf. For instance: A person wants to collect his educational documents from the university but due to some circumstances he is not able to do so; in such a situation a letter of authorization can help him transfer the authority of collecting the document to another person on his behalf.
