RE: What would you do?
What's a teenager doing with a multi thousand dollar jet? Dad has to be involved with this somehow. Don't you have to be of legal age (18) for a contract of any kind to be valid? I would suppose your attorney should be able to track down this kid's age quickly. I know times have changed but when I was in my teens I didn't have things of such value if good old dad didn't have a hand in it.
