4+ Sample Letters for Signature Authorization

A signature authorization letter is a formal letter that allows a person to appoint someone else to be the signature authority for any required work on his/her behalf when unavailable. With this letter, you formally allow another person designated by you to hold power to sign in your absence hence transferring your responsibilities to the same. It is also used when you need a permit to carry out certain tasks & inform the authorities about it.

A signature authorization letter must be kept business oriented as it is used in a professional environment. The clarity and precision of details are equally important as you are offering the right to sign on your behalf to someone else and there must not be any confusions about any point. You must ensure that this must not be put to a wrong use.

When it is Used:

It is used for various purposes such as processing documents, signing certain papers or collecting documents. They are not just restricted to business purposes but are also used when you are unavailable to sign for Bank Deals, Credit Cards, Insurance issues, children custody, etc.
