Third Party Authorization Letter


A Third Party Authorization letter is written by the first party informing the second party that a third party is authorized to perform a transaction of the behalf of the first party. The transaction could be a financial transaction with a financial agency, or it could be a business transaction although other types of tasks can be authorized if they are important and urgent, especially when the first party is unable to attend to it. Hence this is a very versatile yet highly formal letter.

Since this involves a rather serious task, it is important to structure the letter appropriately. Before you start, remember to organize your letter according to the introduction, main body and conclusion division. The introduction is where you state the reason for writing the letter. In the following paragraphs, explain the nature of the third party and who they are. Conclude the letter politely. The letter should be brief and concise.

Subject: Third Party Authorization Letter

Dear Sir,

Thank you for your invitation to attend the Fifth Chemical Research Conference to be held between DD/MM/YYYY to DD/MM/YYYY in New York. I have been a regular visitor to the conference for the past five years, and I have enjoyed being a part of this prestigious conference.

However, this year, I regret to inform you that I shall be overseas during that period on another conference which I have committed to, a year ago. The other conference is a rather important one, and I have been asked to be a panel member of their introductory talk. I had agreed to be a part of it a year back itself. Hence this is a commitment that I cannot possibly get out of.

If it is favorable to you, I would like to authorize my assistant,  Jimmy Carlson, to take my place and share the research findings that our institute has been active in. Jimmy Carlson took his Ph.D. from the University of Texas two years back and had been collaborating with me on my current project for about a year and a half. He is an excellent academician, with a brilliant track record. I request you to consider him in my place.

Please revert with your decision on my authorization recommendation as soon as possible for Dr. Carlson to make the necessary preparations.

Thanking You

Yours Sincerely,

Dr. Andrew T. Whitfield


Concord Institute of Research
