Belong to. Loan to buy a house, as long as the loan before marriage is not paid off, the part repaid after marriage belongs to the joint property of husband and wife and needs to be divided when divorced. The party who has not paid the down payment can generally get 50% of the repayment and its corresponding appreciation after marriage. Divorced real estate involves the following types: the house purchased in full by one party before marriage, which belongs to one party's personal property without special agreement after marriage and is inseparable when divorced. If one party borrows money before marriage and both parties repay it after marriage, the repayment part belongs to the same property. At the time of divorce, the repayment part and its value-added should be divided. Before marriage, if parents contribute to the purchase of a house for both husband and wife, the contribution shall be regarded as a personal gift to their children, except that the parents explicitly indicate that it is a gift to both parties. After the parties get married, if the parents contribute money to buy houses for both parties, they belong to the same property. For the same property, the general principle is to distribute it equally. However, according to Article 1092 of the Civil Code, if one spouse hides, transfers, sells, damages or squanders the same property, or forges the joint debts of the husband and wife in an attempt to occupy the other spouse's property, one spouse can get less of the same property at the time of divorce. After the divorce, if the other party finds the above-mentioned behavior, it may bring a lawsuit to the people's court and request to divide the husband and wife's property again. In addition, there are three kinds of property claims in divorce. First of all, according to Article 1090 of the Civil Code, if one party has difficulties in life during divorce, he can ask the other party for appropriate help. Secondly, according to Article 109 1 of the Civil Code, compensation for damages can only be claimed without fault because of bigamy, cohabitation with others, domestic violence, maltreatment and abandonment of family members. Third, according to Article 1088 of the Civil Code, housewives usually take care of the elderly and children, and have the right to ask the other party for appropriate compensation when divorcing.
