The buy-in is usually split among the existing partners, not put into the business. Then everyone has a fractionally smaller share to account for one more partner, and everything continues to be split according to the new fractional interests. The "consideration" for the buy-in is that each partner will now have a smaller share of profits, and the buy-in is to off-set that reduction. But its whatever you agreed. If there wasn't any agreement, you are headed for trouble.
