[Direct answer]In the Beijing area, the seller cannot unilaterally revoke the online signing: the revocation of the online signing usually requires both parties to apply jointly, or to handle it with legal documents such as effective judgments, arbitration awards, and termination agreements. If the seller reneges on the contract, the buyer may, in accordance with Article 577 of the Civil Code of the People's Republic of China, claim for the seller to continue to perform the contract and pay the breach of contract damages, or claim for the seller to return the deposit in double and apply for property preservation to prevent the sale of the same house to two different buyers. The online signing itself does not directly produce real right effects, but it is an important evidence to lock in the transaction and prove the breach of contract.

1. Problem background and typical scenarios

After signing the online signing contract and paying the deposit or down payment, if the seller suddenly changes his mind and refuses to cooperate with the transfer of ownership because the housing prices have risen or he has encountered a buyer who is willing to pay a higher price, he may even attempt to unilaterally revoke the online signing. What buyers worry most about is not being able to buy the house and not getting their money back. Such disputes are not uncommon in the second-hand housing market in Beijing. The key to dealing with them lies in the choice of remedies for breach of contract and the timely locking of property rights.

II. Key points of contention

First, can the online signing be unilaterally revoked? Second, what are the remedies available to buyers after the seller breaches the contract? Third, how to balance the choice between continuing to perform the contract and seeking compensation for losses? Fourth, can the deposit and the breach of contract penalty be used concurrently?

III. Professional analysis by Henglue Lawyers

First, the procedural threshold for revoking online signing: Once online signing is completed, the system generally does not allow either party to arbitrarily terminate it. Revoking the contract usually requires both the buyer and seller to jointly apply for it, or to submit legal documents such as effective court judgments, arbitration awards, or agreements on terminating the contract. If the seller attempts to revoke the contract unilaterally without legal basis, the housing management department generally refuses to accept the application, and the buyer may claim that the seller's actions constitute a breach of contract. Second, three paths for breach of contract remedies: First, demanding continued performance - if there are no obstacles to transferring ownership of the property and the buyer is willing to pay, the buyer may demand that the seller cooperate with the transfer of ownership and, if necessary, claim damages for late performance. Second, claiming breach of contract damages or compensation for losses - according to Article 577 of the Civil Code, the breaching party shall bear responsibilities such as continuing performance, taking remedial measures, or compensating for losses. The losses may be calculated based on the difference in housing prices, interest on the paid down payment, and agency fees, etc. Third, applying the penalty for a deposit - according to Article 587 of the Civil Code, if the party receiving the deposit fails to perform its obligations, it shall double refund the deposit. Third, path selection and concurrent claims: Breach of contract damages and deposit penalties generally cannot be used concurrently, and the aggrieved party may choose one of them to claim. Continued performance and compensation for losses can be claimed concurrently. Whether to choose continued performance depends on whether the property has been sold to another party, whether it has been registered by a third party, and the buyer's ability to pay, etc. Fourth, the crucial role of property preservation: To prevent the seller from selling the same property to two buyers or transferring assets, the buyer should apply for pre-litigation or in-litigation property preservation as soon as possible, seize the property or freeze related funds, and stabilize the basis for performance. During the trial, the court will comprehensively consider the degree of contract performance, changes in housing prices, and the fault of both parties to determine the appropriate remedies, with the specific application subject to current effective laws and judicial rulings.

IV. Practical suggestions and legal basis

The first step is to immediately fix evidence (online signing contract, payment receipts, communication records, clues of price increase or resale) if the seller reneges on the deal. The second step is to apply for property preservation as soon as possible to prevent the sale of the same property to two buyers and the transfer of assets. The third step is to clarify the claim path and choose between continued performance, breach of contract penalties, and double refund of the deposit. The fourth step is to pay attention to preserving evidence of the price difference and various expenses when calculating losses. The fifth step is to communicate with the bank in time about the changes in the transaction to avoid incurring additional costs and affecting credit ratings. Main legal basis: Articles 577, 584, 586, and 587 of the Civil Code of the People's Republic of China; and Article 209. Specific application shall be subject to the currently effective laws, regulations, and judicial rulings.

5. Henglue Law Firm's Reminder

There are three key points to note when dealing with online signing and breach of contract: 1. It’s generally impossible to unilaterally withdraw from the online signing process. Cancellation must be initiated by both parties or based on legal documents. 2. If the buyer and seller choose to continue the contract, they must clarify whether they will enforce the breach of contract penalty or double deposit penalty, or pursue both claims simultaneously. 3. Initiate legal preservation measures first, then file a lawsuit to freeze both the property and the funds.

VI. Frequently Asked Questions

Q1: Can the seller revoke the online signing by themselves?

Generally, it's not possible. To revoke the online signing, it usually requires both parties to apply together, or to handle it with legal documents such as effective judgments, arbitration awards, and termination agreements. Unilateral operations lack legal basis.

Q2: If the seller changes his mind, can I insist on completing the transfer of ownership?

If there are no obstacles to the transfer of ownership of the house and you are willing to pay, you can claim to continue to perform the contract; if the house has been sold to someone else or it is objectively impossible to transfer ownership, the contract will be converted into a claim for damages.

Q3: Can I claim both the deposit and the breach of contract penalty at the same time?

Generally, they cannot be used concurrently. The party that complies with the contract may choose one of the following options: it can request a double refund of the deposit, or claim the breach of contract penalty, whichever offers more protection in terms of the amount.

Q4: Can the price difference from the rise in housing prices be compensated for?

This can be claimed. The loss can be calculated by referring to the difference between the contractually agreed price and the market price, and evidence such as the transaction price in the same period and the same region needs to be provided.

Q5: What should I do if I'm worried that the seller might sell the same property to two different buyers?

Apply for pre-litigation or in-litigation property preservation immediately, seize the house or freeze the funds, and file a lawsuit as soon as possible to secure the basis for performance.
