Here, experts made the following analysis based on the investment of both parties and the registration of real estate rights:
 (1) . Both parties jointly contribute to purchase and record in the names of both parties
 (2) . Contribution by one party, recorded in the names of both parties
 (3) . One party's contribution is recorded in the name of one party. One: both parties register half and half. Lawyers point out that the situation where one party's contribution is registered in the name of both parties is regarded as the joint property of husband and wife. According to the real estate registration system, as long as the name appears on the property certificate, he or she has a second share: premarital property needs to be paid back. Before marriage, if a person buys a house in his or her own name and the two parties mortgage each other, If they are registered in their own names and need to return the money they paid for the house loan to the other party after divorce, another situation is that a person's name is indeed registered on the property certificate, and the spouse has evidence to point out that he also paid a part of the house loan at the same time, After divorce, the division of property is still determined according to the name on the property certificate. For the value-added part generated by purchasing a house in the name of an individual before marriage, there is still a big dispute. According to several relevant cases, the value-added part of the house belongs to the individual, The majority of people who advocate unequal distribution also put forward the opposite view that they should be compensated for their contributions, so the ownership of property rights should also be properly compensated. This view is only from the perspective of fairness. At present, there is no clear provision for the final recommendations of experts. It is best to make an agreement in advance when this situation occurs, In case of later use, it also avoids many disputes
