What are the laws and regulations on having a Mixed Martial Arts tournament?

I’m wanting to host a Mixed Martial Arts Tournament soon and i wanna know if there is anything legality wise that i have to do or watch out for. Such as if i have to have it in an actual gym or can it be in someones back yard. I plan on it being a big event so help me out here.

I have no idea, man. At a minimum you need the backing of a sanctioning body; an athletic commission or boxing commission.

No offense, but if you need to ask us, you’re nowhere near prepared enough to put on a show.
