Civil Code of the People's Republic of China

Article 143:Civil juristic acts that meet the following requirements are valid:

1) The perpetrator has the corresponding capacity for civil conduct;

2) The meaning is genuine;

3) Do not violate the mandatory provisions of laws and administrative regulations, and do not violate public order and good customs.

Under normal circumstances, as long as the parties voluntarily reach a consensus through consultation, and the agreement signed privately complies with the provisions of laws and administrative regulations, it will have legal effect. If the agreement is signed privately, there are any of the following circumstances: one party concludes the contract by fraud or coercion, which damages the interests of the state; malicious collusion to harm the interests of the state, the collective or a third party; concealing illegal purposes in a lawful form; harming the public interest; Violation of mandatory provisions of laws and administrative regulations.

Then the agreement signed privately is indiscriminate.

A legally binding contract is generally subject to three conditions:

1. The actor who signs the contract should have the corresponding civil capacity.

2. The content of the contract is the expression of the true intentions of both parties.

The expression of intent is true refers to the fact that the expressive person, that is, the actor of the expression of intent, should truly reflect its inner effect, that is, the internal will of the parties is consistent with the external intention, that is, it is true;

3. Do not violate the law and social public interests.

Therefore, regardless of whether it is signed privately or not, as long as the signed second-hand housing sales contract satisfies these three conditions, an irrevocable relationship of specific rights and obligations arises between the parties. Neither party may renege at will, and if it fails to perform, it will have legal consequences or be punished as a breach of contract or as a continuation of compulsory performance. It is necessary to remind both parties here that the law prohibits the listing of houses without a title certificate, so the signing of a sales contract and notarization alone are not protected by law.
