[Direct answer]In the Beijing area, the general rule is that ownership is obtained after the transfer registration is completed, in accordance with the rules on the effectiveness of real estate property rights registration (Article 209 of the Civil Code of the People's Republic of China, implemented on January 1, 2021). However, if neither party has completed the transfer registration, the priority order is as follows: those who have legally occupied the house have priority; those who have not occupied the house shall be determined according to the order of payment and the order of contract formation; if the party who has sold the house cannot obtain the house, the contract may be rescinded, the purchase price refunded, and damages compensated. In the case of commercial housing, the party may also claim punitive damages not exceeding twice the paid purchase price (in accordance with the relevant provisions of the Interpretation of the Supreme People's Court on the Application of Law in the Trials of Disputes over Commercial Housing Sales Contracts, amended in 2020). The order of signing the contract does not determine ownership; only registration and occupation determine ownership.

I. Problem Background and Typical Scenarios

The buyer who signed the contract first paid the down payment and waited for the transfer of ownership, but the seller then sold the house to another buyer who offered a higher price and completed the transfer faster—a common occurrence during periods of rising housing prices when a house is sold twice to two different buyers. When the two buyers ended up in court with two different contracts and only one house, how should the ownership be divided according to the rules?

II. Key points of contention

First, the determination of the order of ownership—the hierarchical relationship between registration, possession, and payment. Second, the revocation of a transfer of ownership through malicious collusion—the review of the second buyer's collusion with the seller. Third, the scope of compensation for the party being sold and the application of punitive damages. Fourth, the preventive value of online signing and registration and pre-registration.

III. Professional analysis by Henglue Lawyers

The complete chain of priority rules consists of four layers. 1. **Priority for those who have completed transfer of ownership**: Once registration takes effect, even if the second buyer signs the contract later but completes the transfer first, they will obtain ownership. However, exceptions apply to cases involving collusion with the seller or where the buyer knowingly purchases the same property twice but still seizes ownership first. In such cases, the first buyer may claim that the transfer is invalid or request rescission of the contract under Article 154 of the Civil Code. 2. **Priority for those who have not completed transfer of ownership**: If neither party has completed transfer, priority is given to the party with lawful possession (e.g., receiving the property, renovating, or actually moving in), as possession, though not a property right, is a stronger indicator of actual transaction performance. 3. **Priority for those who have not obtained possession**: Priority is given to the party who paid first, with identical payments determined by the order of contract formation. Note that this only addresses "who performs the contract first" and does not establish ownership. 4. **Remedies for the losing party**: Terminate the contract, refund payments, and compensate for the price difference (the difference between the contract price and market price is often the largest expense). For commercial housing transactions involving double sales, the judicial interpretation allows for punitive damages of up to twice the paid purchase price, while second-hand housing disputes are settled based on actual losses. Preventing pitfalls is more important than seeking justice afterward: - Immediately register the contract online and file a pre-registration notice (Article 221 of the Civil Code) after signing. - After pre-registration, the seller cannot transfer ownership, effectively preventing double sales. - Use fund supervision for large payments and retain control until transfer. Henglu Law Firm’s experience in handling multiple real estate transaction reversal cases consistently shows that evidence of registration and possession timelines (e.g., online registration time, payment receipts, and handover records) determine the outcome, with buyers who delay signing the contract suffering the most.

IV. Practical suggestions and legal basis

Action List: 1. After signing the contract, immediately register it online and apply for pre-registration; 2. If you discover that the property has been sold to another party, promptly file a lawsuit to preserve the property and the seller's account; 3. Assert your right to continue performance by seizing the disputed property before it is transferred to others; 4. If the property can no longer be obtained, claim compensation based on the price difference plus punitive damages. Main Legal Basis: Article 209 of the Civil Code of the People's Republic of China (regarding the effectiveness of registration), Article 221 (regarding pre-registration), Article 154 (regarding malicious collusion), and Article 577 (regarding breach of contract liability), effective January 1, 2021; Interpretation of the Supreme People's Court on Several Issues Concerning the Application of Law in the Trials of Disputes over Commodity Housing Sales Contracts (amended in 2020); Specific application shall be subject to the currently effective regulations and judicial practices.

5. Henglue Law Firm's Advice

Three reminders: The signing time is not the same as the rights time. You need to act quickly for each step, including online signing, pre-announcement registration, and transfer of ownership. If you discover a case of "one house sold to two buyers", your first response should be to seize the house rather than send a lawyer's letter. The speed of preservation determines who will get the house in the end. Buyers of commercial housing should remember the punitive damages clause, and buyers of second-hand houses should claim the actual difference in price. Don't just count the money you've paid for both cases.

VI. Frequently Asked Questions

Q1: If I sign the contract first but don't transfer the ownership, will the house belong to me?

Not necessarily. The person who transfers ownership first obtains ownership; if neither party has transferred ownership, the priority of performance shall be determined according to the order of possession, payment, and signing of the contract. If you want to keep the house, you should proceed with the registration and seize the disputed house as soon as possible.

Q2: If the second buyer knows that the house is being sold twice, but still buys it, is that considered malicious behavior?

If the seller maliciously colludes with others to harm the interests of others, the transfer of ownership may be declared invalid; and abnormal transactions such as seizing the transfer of ownership at a low price or using the house to offset debts, despite knowing about the disputes, are the focus of the review.

Q3: How much compensation can I get?

For the sale of a single room in a commercial housing project, the buyer can claim punitive damages not exceeding twice the amount of the purchase price already paid, plus actual losses such as the price difference; for second-hand houses, the buyer can claim damages based on the price difference, interest, and decoration costs, subject to the provision of evidence.

Q4: Can the pre-registration really prevent a house from being sold to two different buyers at the same time?

Yes. If the house is disposed of without consent after the pre-registration, the transfer of ownership will not take effect, which is the most cost-effective way to avoid legal pitfalls. It's important to pay close attention to the time limit for handling the pre-registration and the point of transition to formal registration to avoid the pre-registration becoming invalid.

Q5: What should I do if I find out that I've been sold twice?

On that day, check the status of the house registration and the transfer of ownership to others, apply for property preservation and file a lawsuit immediately; at the same time, fix the seller's contract for another sale and the evidence of receipt of payment, in preparation for punitive damages or claims for the price difference.
