Answer 1

You can work on a contract that outlines the specifics of the investment, and what happens when the investment works (or doesn't). Also agree on the profit-sharing. Lastly, check that you have all his contact details, but most important is his agreement to go to a court if things turn sour.

Answer 2

Prepare to lose the friendship.

If you are worried about this, don't make the investment.

If he disappears, and this is not a loan with collateral, you are screwed.

Answer 3

ALWAYS GET A CONTRACT SIGNED IF YOU DONT YOU DONT HAVE A LEG TO STAND ON IF HE DOES DO ONE
