New Buisness partnership advice needed

[cheferson]

So I met with an owner of a local farm . She has started to grow mushrooms , but has almost no experience or knowledge in their cultivation. Thats where I come in , I have lots of cultivation experience and some good contacts in the industry . She already has a successful farm in operation. She has all the insurance , property, storage , green houses and capital to get it all going.

She is interested in maybe forming a separate mushroom business with me in the future. For now she wants to do a some what informal partnership. Ill supply free labor and knowledge and she will supply the space, capital and her distribution network. Then we'd spilt the profits .

What can I do to protect myself from teaching her what I know and giving free labor to get it going and then getting tossed to the side? Not that I think she is this kind of person , but I want some kind of legal document to solidify the partnership to protect myself .
