Partner Contract Legal In All States

Question about Partner Agreement?

I am to partner with other/s and would you share a simple partner agreement that is legal in all states. In other words my partners might live in the same state I do Or might live in a different state.

Have found one online but wanted a recommendation here if possible?

I didn't find a partner agreement on Dean's website as in two or more working together be it bird dogging or flipping together.

For example you and I agree to Bird dog and or flip but we would be required to invest say $1000. each?
We would each get the $1,000 investment back when the property closes. We might flip a house together and invest the same $1000 and still work with cash buyers.

There are times when you want to work with someone and both feel better with a simple partner agreement in place.

Some cash buyers require an up-front investment even for a bird dog. I'm finding that these cash buyers pay out is Much higher! The cash buyers do return the $1000. investment funds to the investor/s (Bird dog), along with a commission of $3000. to $6,000.

Thank you!
