and have questions about.
Are there any instructions on how they want this document returned?
Playing devils advocate here. Lets just assume this is legal. You sign it. How is this supposed to be returned to prove you did sign it and sent it back?
The big red flag for me is this sentence
"Your failure to duly and timely remit the enclosed affidavit will put your status as a delegate in jeopardy"
It is not clear if you don't sign this that you will be removed as a delegate. It say it will put your status in jeopardy.
Jeopardy: hazard or risk of or exposure to loss, harm, death, or injury
I am no law expert but I do not see how this thing could be binding.
