Legal analysis: Generally speaking, during the marriage relationship, the property of both parties or one of them belongs to the joint property of husband and wife and should be owned by husband and wife. Therefore, even if the down payment for buying a house after marriage is made by the man, the property is also the joint property of the husband and wife, and the two sides should share it equally when divorcing. However, if the down payment of the house property is invested by the parents of the man and registered in the name of the man, and there is evidence to prove that the parents contributed the down payment, then the down payment part belongs to personal property, while the two parties repay the loan and the value-added part of the house property belongs to the husband and wife. And if it can't be proved that one of the parents contributed, it will be regarded as the joint property of the husband and wife.

Legal basis: Article 1062 of the Civil Code of People's Republic of China (PRC), the following property acquired by husband and wife during the marriage relationship is the common property of husband and wife and belongs to them:

(1) Wages, bonuses and remuneration for labor services; (2) Income from production, operation and investment; (3) Income from intellectual property rights; (4) Inherited or donated property, except as provided for in Item 3 of Article 1063 of this Law; (five) other property that should be owned by * * *.

Husband and wife have equal rights to dispose of the same property.
