Signing an intellectual property agreement to protect a business idea

Hi!

I have an idea and want to develop it into MVP. I am in the UAE and my friend who is in the US wants to help me to develop the product.

I trust him but without a legally binding document, there could be issues at the later date. We will register the company after trying out our MVP.

My question is, what sort of legal contract can I do with him?

Note: we haven't registered the company and he is in the US. I need to protect my MVP and he should use the idea to develop his own product.
