Hello, first of all, the house was bought before marriage and will not be recognized as the joint property of husband and wife. If the husband and wife repay the loan together after marriage, the part that belongs to the common property is only the common repayment part and the corresponding value-added part. If the husband and wife do not use the joint property to repay the loan after marriage, then there is no part of the joint property of the husband and wife, but it is necessary to prove that the joint property within marriage is not used to repay the loan.

According to article 1063 of the Civil Code, the following property is the personal property of one spouse:

(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.
