Signing 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

Also, the situation of use must be mentioned explicitly leaving no rooms for confusion & avoiding misuse of the power.

    Basic Things to Keep in Mind When Writing a Signature Authorization Letter

    Signature authorization letters are not limited to be used for business and corporate processes; some are usually made for matters related to child custody, bank transactions, loans and issuance of insurance, and many more application procedures.

    Some of the Basic Things to Keep in Mind Include:

    • Ensure that you keep in mind the duration of the letter’s effectiveness. Write the exact date on which the transaction is set to begin and the date where the authorization signatory will lose their power to act on your behalf.
    • The tenure duration should be clearly identified so that any miscommunication or misunderstandings can be prevented from happening. Doing this will help you limit not only the activities in which the signatory will be involved but also the time where you can be represented by them.
    • Remember that a signature authorization letter should be addressed to the person who will require your Signature for specific transaction or documents and not you, the person whom you are authorizing to represent you when you are not available
    • Be very detailed when discussing the situation of the use of the Signature. You have to properly present specific instances that required the Authorization on your behalf during your absence. There should be no gray areas, misleading information, vague discussions, incomplete process presentations, and any confusing statements that may result in the abuse or misuse you have given to your representative.

    Importance of a Signature Authorization Letter

    Assigning someone to sign materials and documents during your absence can go in two different ways. Your plants and intentions may be fulfilled, or the power you have granted the representative may be abused. This is why it is crucial that you come up with an effective authorization letter that can set the direction of the transaction.

    Here are some of the basics why it is important for you to create an authorization letter whenever you plan to give your representative the right or the authority to sign specified documents on your behalf.

    • The signature authorization letter can be used as a reference if there is a need to review the responsibilities that you have granted to the person who is tagged as your authorized representative. This can help businesses, establishments, and/or organizations to clarify concerns and issues pertaining to the transaction.
    • The letter can help remove any confusion about the activity. If you are looking to authorize someone to act on your behalf, you have to make sure that you are very clear with the range of the documents or materials that the individuals can sign on your behalf, as well as the decisions that they can make on your behalf.
    • A signature authorization letter is often required whenever you are looking to assign someone else to sign a document on your behalf if you want a transaction where your Signature is required to push through and be realized when you are not available to sign the documents.
