Hi Robert. Congratulations on being in the position to expand your fitness business! Wow, a ‘template’ agreement to form a partnership. I would caution you that in our business, there are definitely places where you can ‘cut corners,’ but in my opinion, drafting a partnership agreement with an unrelated person/entity would NOT be the place I would want to do that if I were you. I highly recommend finding a local attorney with experience working with small business contracting (preferably in the fitness industry) to help you with this. I think that this is too important to try to fashion such an agreement by yourself unless you have legal training/education.
My two cents!
I wish you luck!
