The Alamy form really does a good job of showing where the Model and Photographer's information goes. If the clause where the word Consideration is the place you are questioning then what I am saying about giving something of value to receive the rights to the image is what I am trying to talk about.
Put $1 and tell your friend you owe the money if there is a question. Buy your friend a cup of coffee or something. Put "one-cent" if or if you would like put "Nothing." Legally (at least according to what I knew as a Financial Services "Knowledge worker") A contract requires consideration (I will give you X) and performance (if you will do, or give me Y). Without both there is no contract.
Getty's release does it differently, but the result is the same. The first paragraph starts, "For Consideration herein acknowledged received..." and in definitions says "'CONSIDERATION' , means $1 or something else of value..."
The only person who would challenge the consideration in court would be your friend. It is old common law and I would doubt that there would be a challenge from a friend or relative in court. I would not know Alamy's stand. I would guess they have an attorney that would make you put something there, or they would not have left that part in. If it were me, I would put $1.
This question is why I don't do people. I hope there is a lawyer out there that can clarify.
And I didn't think I was going to have to use my left brain today. Oh, well...
