Legal analysis: Generally speaking, if the house purchased before marriage needs to be repaid jointly after marriage, the value-added part of the house and the joint repayment part belong to the joint property of husband and wife. During the marriage, one party with registered property rights should obtain the consent of the other party when selling the property. During the divorce, if one party arbitrarily disposes of the shared house, causing losses to the other party, and the other party requests compensation for the losses, the people's court shall support it.

Legal basis: Interpretation of marriage and family in Article 28 of the Civil Code of People's Republic of China (PRC) (China) (1).

If one party sells the house jointly owned by husband and wife without the consent of the other party, the third party purchases it in good faith, pays a reasonable consideration and has registered the real estate, and the other party claims to take back the house, the people's court will not support it. If one spouse arbitrarily disposes of the shared house, causing losses to the other spouse, and the other spouse requests compensation for the losses during the divorce, the people's court shall support it.
