If you need to write an authorization letter for someone, here is a sample authorization letter template.
This letter is to certify that I, [Your Name], hereby authorize [relation/designation], [Name of applicant] on my behalf for the [concern]. Due to inevitable circumstances, I am unable to present myself on the [specified date], thus your consideration is requested. My applicant shall act for me and operate with authority equivalent to mine.
I have asked the applicant to provide you with identity proofs for your authenticity verification purposes. Kindly cooperate with the same and allow [him/her] to carry out the required operations unhindered for me.
Thank you and feel free to contact me at [Phone no.] for further clarification!
