If you buy a house before marriage and repay the loan after marriage, if there is an agreement that it is the joint property of husband and wife, it will be the joint property of husband and wife. If there is no agreement, it is generally not the joint property of husband and wife. When divorcing, the other party has the right to request the division of the joint loan repayment portion and the appreciation portion of the house. "The Interpretation of the Supreme People's Court on the Application of the Marriage and Family Section of the People's Republic of China and the Civil Code (1)" Article 78: One spouse signs a real estate sales contract before marriage, uses personal property to pay the down payment and obtains a bank loan, and uses the property after marriage to If the couple repays the loan with the same property, and the real estate is registered in the name of the party who paid the down payment, the real estate will be handled by agreement between the two parties in the event of divorce. If an agreement cannot be reached in accordance with the provisions of the preceding paragraph, the people's court may rule that the real estate belongs to the party who registered it, and the unpaid loan shall be the personal debt of the party who registered the real estate. For the amount paid by both parties to repay the loan after marriage and the corresponding increase in property value, upon divorce, the party registering the real estate shall compensate the other party in accordance with the principles stipulated in paragraph 1 of Article 1087 of the Civil Code. .
