Legal Question in Business Law in Arizona

Re: royalty rights

When using anyone's name, picture or identity in a commercial setting for advertising, trade use or commercial use always get a proper written consent form signed in advance, or don't do it. The problem here is that a minor cannot sign it. When they are 18, any consent, whether by their parent or by themselves, can be set aside. Photographers alway get model releases from those they take pictures of, even in public, if they intend to use the photos for commercial use. This seems like overkill in a family setting, but by the nature of your question it may be prudent.
