Hello. I have been doing martial arts for a little over 15 years now. Its always been my dream to become an instructor. After just recently receiving my BB, This dream is coming closer to fruition. I started training a few interested individuals in a public park 2 people to be exact. After my training session someone had approached me and asked if i had a license to practice and teach? Well it was more like " I hope you have a license to practice and teach!" To my confusion i simply replied "Well I do have certification proving Im a black belt" Gave me the 1000 yard stare and i walked off. So here is my concern, Short of signing a contract with a landlord regarding lease agreements, do you need legal documents to teach and train in a park or public place (beach, my backyard ect....). Do you need special licensing to teach in a facility like a rented space like in a mall or plaza or recreation center? How many of you guys have your hands registered? I am only asking because I dont want to get in trouble and I dont want to give other practitioners a bad rap. At this time I am going tot ask my predecessors, but i would like to here more from people who have been instructing for a while. Please bestow me with your knowledge.......
