Legal analysis: one of the husband and wife bought a house with a mortgage loan before marriage and obtained a real estate license. After marriage, both husband and wife pay back the same house. After divorce, although the house is purchased by one party before marriage, the value-added part of the house after marriage and the part jointly repaid by the husband and wife shall be regarded as the same property, unless otherwise agreed by the husband and wife. It should be noted that the repayment part of * * *, whether it is repaid by one party's personal salary or by the wages of both parties, should be recognized as the property of husband and wife. Of course, if one party can really prove that its repayment funds come from personal premarital property, then this part should not be recognized as marital property.

Legal basis: Civil Code of People's Republic of China (PRC).

Article 1062 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.

Article 1063 The following property is the personal property of one of the spouses:

(1) one party's premarital property;

(2) Compensation or compensation obtained by one party for personal injury;

(3) Property that is determined to belong to only one party in the will or gift contract;

(4) Daily necessities used exclusively by one party;

(five) other property that should be owned by one party.

Article 1065 A man and a woman may agree that the property acquired during the marriage relationship and the property before marriage shall be owned by themselves, wholly or partly, and partly. The agreement shall be in writing. Where there is no agreement or the agreement is unclear, the provisions of Articles 1062nd and 1063rd of this Law shall apply.

The agreement between husband and wife on the property acquired during the marriage relationship and the property before marriage is legally binding on both parties.

The husband and wife agreed that the property acquired during the marriage relationship should be owned by each other, and if the other party knows the agreement, the personal property of the husband and wife should be used to pay off the debts owed by the husband and wife.
