How to write the equity distribution in the contract? My friend asked me to buy stocks. Let me hold 20% of the shares, and when the company develops, I will bring in two more partners.

You only account for 20%, so the contract says that he accounts for 80%. Just wait for the people behind to rewrite the contract. As a company, it is not recommended to have too many partners. Nine of 10 did not make it to the end. I have experienced it myself, and many friends around me are so scattered. Time will tell, which reality.
