[Direct answer]The ownership of the house is not determined by the principle of "first come, first served", but by the priority rules: buyers who have completed the registration of ownership have priority (the property rights have been transferred); if none of them have completed the registration, buyers who have legally occupied the house have priority; then comprehensive factors such as the degree of payment, online signing and filing, and the order of contract signing will be considered; buyers who cannot get the house will not suffer losses in vain — they can terminate the contract, demand the return of the paid purchase price and interest, and compensation for losses. If the seller maliciously sells the same house to two buyers (knowing that the house has been sold and transferred to others), the buyer can claim punitive damages, which can reach up to twice the amount of the paid purchase price. A case in Zunyi reported by the Supreme People's Court Bulletin and the judgment guidelines issued by the Beijing No. 3 Intermediate Court have clearly explained the priority rules.

I. Problem Background and Typical Scenarios

During the period of fluctuating housing prices, the phenomenon of "one house sold to two buyers" is quite common. The buyer who signed the contract first has paid the down payment but not yet completed the transfer of ownership. The seller, anticipating a rise in housing prices, changes his mind and sells the house at a higher price to the second buyer and quickly completes the transfer of ownership. With two buyers each holding a contract, there is only one owner of the house — whoever takes possession of the house will get the money, and the rules will decide who gets what.

II. Key points of contention

First, the rules of priority of ownership. Second, punitive damages for malicious breach of contract. Third, the legal significance of possession and the opposability of registration. Fourth, the buyer's preemptive preventive measures.

III. Professional analysis by Henglue Lawyers

The first layer is the practical application of the priority rule: The Shunyi case in the Supreme People's Court Bulletin established a comprehensive evaluation framework - the villagers' group subscribed to the storefront, paid the purchase price, and received possession and lease in 2007. The developer then signed a contract with a third party and registered the pre-sale. The bulletin explicitly states that the performance of the "one house, two sales" should be evaluated comprehensively from the aspects of contract authenticity, contract signing time, payment level, registration situation, possession facts, and pre-announcement registration. The interests of the buyer who has already legally possessed the property should be protected. The judgment guidelines issued by the Beijing No. 3 Intermediate Court further set out the order of property protection priority: registration, delivery, legal possession, and contract performance. It is not based on the principle of "first come, first served". The practical conclusion for buyers is: registration is king, possession is key. Those who have signed a contract but not completed online signing and possession have the most vulnerable rights. The second layer is the deterrence of punitive damages: maliciously breaching contractors can be sentenced to punitive damages. The rules established by the Judicial Interpretation on the Sale of Commercial Housing stipulate that if the seller sells the house to a third party after signing the contract, resulting in the failure to achieve the contractual purpose, the buyer may request the return of the paid purchase price and interest, compensation for losses, and may request the seller to bear compensation liability not exceeding twice the paid purchase price. The applicable condition is "malice" - knowing that the house has been sold again or colluding with the third party. Ordinary breaches (objectively unable to perform) are handled with general compensation for losses. If the intermediary fails to fulfill its duty of honest reporting, it should also bear responsibility. The No. 3 Intermediate Court clarified the intermediary's obligation to verify the authenticity of the house. If the intermediary arranges the deal despite knowing about the "one house, two sales", it will be jointly liable with the seller. The third layer is the defense and attack of possession: legal possession (delivery, key handover, occupancy, and rent collection) carries great weight in the priority competition, as confirmed by two public cases. The elements of possession recognized are actual delivery and continuous possession. "Manufactured possession" (symbolically taking the key on the day of signing the contract but not actually occupying the house) has weak evidentiary value. Malicious buyers (knowing that the house has been sold again, buying at a low price, or colluding with the seller to backdate the contract) may have their contracts declared invalid for malicious collusion. Buyers who have paid the full purchase price and actually occupied the house can still seek ownership and transfer through litigation even if the seller has registered the online signing with others. The fourth layer is the buyer's pre-prevention: online signing and registration on the day of signing (locking the uniqueness, and unable to sign a second contract after online signing), promptly delivering possession, checking the property ownership and sealing status before making large payments, and, if necessary, registering a pre-announcement (property rights effectiveness, no valid disposition without consent). If signs of "one house, two sales" are found (the seller delaying transfer of ownership, the house being renovated and occupied by others), immediately apply for property preservation and sealing the property - the preservation and sealing freeze the transfer channel, and the property cannot be moved during litigation. In terms of litigation strategy, the choice between ownership confirmation and rescission claims should be based on the actual position in the priority competition. Those with a better position should fight for the house, and those with a weaker position should seek compensation.

IV. Practical suggestions and legal basis

The first step is to complete the online signing and filing on the signing date and take possession of the delivered property as soon as possible; the second step is to conduct a property search before making large payments and, if necessary, handle pre-registration; the third step is to immediately apply for property preservation if a case of selling the same property to two buyers is discovered; and the fourth step is to choose between confirming ownership or waiving claims according to the priority order, and simultaneously claim punitive damages against malicious breaches of contract. The main legal basis: Articles 209, 221, and 577 of the Civil Code of the People's Republic of China, and Article 8 of the Interpretation of the Supreme People's Court on Several Issues Concerning the Application of Law in the Trials of Disputes over the Sale of Commercial Housing Contracts; the specific application shall be subject to the currently effective provisions.

5. Henglu Law Firm's Reminder

The three key points of "one house, two sales, and three statements": Registration is the key to ownership; handle the online signing and filing on the same day; those who maliciously sell the same house twice may be fined double the amount; and real estate agents who fail to fulfill their duties will be held jointly liable. If you detect any suspicious signs, take immediate protective measures; and freezing the transfer of ownership will give you the initiative in the dispute.

VI. Frequently Asked Questions

Q1: What should I do if I sign a contract first but don't transfer the ownership, and then the house is sold to a second person and the ownership is transferred to them?

The house belongs to the second person who has completed the transfer of ownership. If you terminate the contract and claim the return of the housing payment interest and losses, the seller may claim punitive damages not exceeding twice the amount of the payment made, if the seller acted maliciously.

Q2: If neither of the two contracts is transferred, who will own the house?

It is determined based on the comprehensive factors of legal possession, payment level, online signing and filing, and signing order. Buyers who have legally possessed the property and made full payments enjoy the greatest advantage.

Q3: What is the purpose of pre-registration for a film or TV show?

After the pre-sale registration, any disposition of the house without your consent will not have legal effect on the property rights. This is the most powerful preventive tool for buyers. It is recommended to handle the registration as soon as possible after signing the contract.

Q4: Do intermediaries have to compensate if they conceal the fact that a property has been sold twice?

The intermediary has the obligation to verify and report faithfully. If the intermediary conceals information that they know or should have known, they shall bear corresponding compensation liability. The sharing of liability with the seller shall be based on the proportion of fault.

Q5: How to prevent sellers from delaying the transfer of ownership?

The contract clearly stipulates the deadline for transferring ownership and the high-amount breach of contract liability, with the payment schedule being tied to the transfer of ownership. If the transfer of ownership does not take place on time, legal action will be initiated immediately and protective measures will be taken. Don't wait indefinitely.
