Now that the house has been bought, the man has also paid a down payment. In a sense, the house belongs to his personal property before marriage. Although the part repaid with the same property after marriage belongs to the same property, what you enjoy is basically asking for corresponding compensation.
Suggestions to protect your rights:
1. In the dowry: parents agree in writing to give you 200,000 property before or after marriage, but the gift contract states that you will give it yourself and it is notarized;
2. If it is determined that you need to use your property or * * * to repay the loan with the same property, then you can suggest that the man sign a written property agreement with you, stipulating that the house is the joint property of husband and wife, and then notarize and register the names on the property certificate of the house as the two of you, so that you can have general house ownership.
