You guys clearly need a new lawyer because he's telling you a bunch of bullshit about what is necessary to host international contests. You do not need international lawyers, your lawyer does need to create a legal agreement that works for multiple countries, which is possible, and download the necessary paper work from those countries for any international winners. I'm not saying it will be really easy but it is clear your lawyer does not want to do the work.
If it's so simple, please, by all means, produce these papers for us. You clearly know what you're talking about here, so it should be no issue. Heck, maybe we should extend you a job offer if you can come through with it.
