Interpretation III of Marriage Law makes it clear for the first time that the house purchased by a husband and wife for their children after marriage, which is registered in the name of one parent and their children, belongs to the common property of both parents and their children. In this case, it is regarded as a gift from the investor's parents to one of their children.

However, if your father pays in full and you don't participate in the loan repayment and joint mortgage, there is no problem. If you also participate in the mortgage repayment, then your repayment part belongs to the joint property of husband and wife. In case of divorce, one party to the property right registration shall compensate the other party in accordance with the principle stipulated in the first paragraph of Article 39 of the Marriage Law.

The second suite is a family unit. You already have a set of partial property rights. If your husband invests in buying a house, it belongs to the second suite. Unless, of course, you are deprived of the property rights of your father's apartment.
