Securing a deal prior to entering into a 50/50 partnership

[Orlando Paz]

On numerous occasions I have heard that if you don’t have any money to fund a deal, simply partner up with someone who can provide the funds and make a 50/50 split on the profits.

My question on this approach is…

How do I secure a deal from being swiped from underneath me, when I present it to other investors?

I would like to think that this is something that does not happen, but if there are other investors that can simply acquire the property without jumping into a partnership, what’s to keep them from simply going to the source, once you provide information about a given deal?

Not sure if this would be the appropriate forum for my question, but any feedback is appreciated.
