Legal analysis: It is valid. Husband and wife have a house, and the husband and wife have equal rights to dispose of it. There is no requirement that they must be disposed of together to be legal, but the law stipulates that if one party privately disposes of the property owned by the other party and causes losses, the spouse can sue the party selling the house for compensation.

Legal basis: Article 311 of the "People's Republic of China and Civil Code" If a person without the right to transfer real estate or movable property transfers it to the transferee, the owner has the right to recover it; except Unless otherwise provided by law, the transferee shall obtain ownership of the real estate or movable property if the following circumstances are met:

(1) The transferee transfers the real estate or movable property in good faith;

(2) Transfer at a reasonable price;

(3) The transferred real estate or movable property that should be registered in accordance with legal provisions has been registered, and if registration is not required, it has been delivered to the transferee.

If the transferee obtains the ownership of real estate or movable property in accordance with the provisions of the preceding paragraph, the original owner shall have the right to request compensation for losses from the person without the right to dispose of the property. If the parties acquire other property rights in good faith, the provisions of the preceding two paragraphs shall apply.
