Determine the type of authorization letter that's desired. Is the letter intended to convey authority for another person to act in a position on a temporary basis while a person is ill? Perhaps the authorization is being given to allow access to numerous files and other company resources.
Secure the address and name of the person in receipt of the letter of authorization. Only the person named in the text of the letter has the permission to implement the outlined provisions.
Write the first paragraph in the body of the letter. Write a general description of the types of abilities or resources being granted in the letter of authorization. Use a bullet-point formatted list to keep the information organized and simple to understand. Include a sentence that allows for privileges to be extended as needed.
Write the next couple paragraphs of your authorization letter. Specify the scope or range of the authority being given. Include any auxiliary authorization that may not be related or apparent to the main purpose at the time you draft the letter. For instance, a letter of authorization may allow someone to pull additional medical records if the issuer is diagnosed with a new medical condition.
Write the final paragraph of the letter of authorization. Specify the date range for the authorization period. If the authorization period is indefinite, only include a starting date and a statement that the letter remains in effect until further notice is made.
Close the letter by stating the position/relationship the grantor holds that allows such authorization be given to another person. This can be as simple as including a job title such as president/CEO or a relationship status such as mother/sister. This serves as proof that the letter does indeed extend privileges and rights to the recipient.
