When it comes to profit distribution, it must be distributed according to the proportion of capital contribution, but if you are a manager and the other party or parties only contribute, you can't ignore your labor. The property after the dissolution of the enterprise is also divided in proportion. Of course, the debts of enterprises are also paid in proportion, and you are all jointly and severally liable indefinitely. That is to say, if one of you has no money to repay the debts of the enterprise, the creditor has the right to ask any one of your partners for money, and the law stipulates that you cannot fight.
A good cooperation agreement means that you have succeeded halfway. Nothing else seems important. Partnership is actually a good way to invest.
