Sample Letter of Authorization

Send a letter of authorization to indicate that you are authorizing something or someone on a particular matter. As is the case with all letters, the style and wording you use in a letter depend on the specific circumstances. Many types of authorization letters relate to legal matters, so be sure to consult relevant laws as you write these letters. Also obtain the counsel of an attorney as needed.

Use appropriate tone in your letters, depending on your audience. For example, if you know the recipient well and are not sending a formal letter, you can use more casual tone. Most business letters call for a formal style. In general, it is best to keep letters as short and concise as possible while still communicating the relevant information.

Feel free to customize and modify any of these letters according to your individual needs.

NOTE: In all letters, brackets indicate information that you should fill in. Remove the brackets when you have modified the text to your liking.
