Husband and wife have the right to represent each other, and the signatory may dispose of this right on behalf of each other. Therefore, the contract should be regarded as valid. The house purchase agreement is valid after being signed by both husband and wife. As long as the signing of the agreement is the real intention of the buyers and sellers of the house, the contents of the contract are legal, and the contract is valid after being signed by the buyers and sellers. If the above conditions are not met, the contract is invalid.

According to the law, the real right of immovable property is publicized through registration. Therefore, if the real estate license records the names of both husband and wife or the name of the non-signatory party, it is considered that the purchaser has the obligation to review the ownership status of the house according to the house ownership certificate.

When the house * * * is registered in the names of both husband and wife or non-signatory, the buyer only signs the house sales contract with one husband and wife, and the signatory has not obtained the authorization of his spouse, at this time, it is not easy to assume that the buyer is in good faith. According to the law, "if a person who has no right to dispose of other people's property obtains the right to dispose of it after the obligee has ratified it or the person who has no right to dispose of it has entered into a contract, the contract is valid". Therefore, without the consent of the seller's spouse, the effectiveness of the house sales contract signed under the above circumstances is to be determined. If the seller's spouse finally refuses to ratify the validity of the contract, the contract cannot be effectively handled. On the other hand, if the house is registered only in one spouse, the house sales contract is signed by the registered obligee.

Unless otherwise provided by law, in any of the following circumstances, the transferee obtains the ownership of real estate or chattel:

The transferee is in good faith when accepting real estate or movable property;

(2) Transfer at a reasonable price;

(3) The transferred immovable property or movable property that should be registered according to law has been registered, and the transferred immovable property or movable property that does not need to be registered has been delivered to the transferee.

(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;
