[Direct answer]In the Beijing area, it is not appropriate to evaluate the effectiveness of agents solely based on a uniform "success rate". Whether a second-hand housing transaction dispute can be supported primarily depends on the contractual provisions, evidence of performance, and the basis of the claim, rather than the proportion promised by the agency. According to Article 577 of the Civil Code of the People's Republic of China (effective January 1, 2021), if a party fails to perform its contractual obligations or performs them in a manner inconsistent with the contract, it shall bear contractual liabilities such as continuing to perform the contract, taking remedial measures, or compensating for losses. In cases such as the seller refusing to transfer ownership, selling the same property to two different buyers, or concealing the property being sealed up or mortgaged, the court usually determines the breach of contract based on the evidence and orders the seller to bear responsibility. If the evidence is insufficient or the buyer itself has breached the contract, the claim may be rejected. It is recommended to first evaluate the evidence and expectations of the case, and refer to the relevant columns for more information.Real estate transactions and construction projects.

1. Problem background and typical scenarios

These types of disputes are common in several situations: First, after the price of the house fluctuates, one party breaches the contract, and the seller refuses to transfer the ownership or the buyer refuses to pay; Second, during the transaction, it is found that the house has been sealed up, mortgaged, or there are disputes over co-ownership; Third, disputes arise due to the failure to fulfill the commitment to transfer the household registration or the failure to fulfill the commitment to the school district; Fourth, the buyer claims that the loan was not approved and that it was not his fault, demanding the termination of the contract; Fifth, when the transaction is conducted through an intermediary, the deposit, commission, and intermediary responsibilities are intertwined. It's understandable to pay attention to the effectiveness of the agent before entrusting him, but a more practical approach is to first sort out the evidence and the basis of the claim. When the Beijing district court tries such cases, it usually proceeds in three levels: the validity of the contract, the facts of the breach of contract, and the scope of the losses. The rules for similar contract disputes can be referred to.Business and contract disputes in enterprisesColumn.

II. Key points of contention

Focus 1: The validity of the contract and the possibility of continued performance. Whether the house can be transferred when it is sealed up or mortgaged directly affects the choice of remedies. Focus 2: Whether the penalty for breach of contract is too high. According to Article 585 of the Civil Code, if the agreed penalty for breach of contract is excessively high compared to the actual losses, the court may appropriately reduce it. In practice, it is often weighed comprehensively based on the actual losses, expected benefits, and the degree of fault. Focus 3: The application relationship between the deposit and the penalty for breach of contract. According to Article 588, when one party breaches the contract, the other party may choose to apply the penalty for breach of contract or the deposit clause, but cannot claim both at the same time. Focus 4: The determination of the loss of price difference. Whether the price difference of the house can be compensated when the housing price fluctuates needs to be supported by appraisal reports or transaction records of the same period. Focus 5: The distribution of the burden of intermediary fees and commissions. Focus 6: The integrity of evidence, such as chat records, payment receipts, and online signing materials. Specifically, the current effective laws and regulations and judicial rulings shall prevail. For matters involving recovery and enforcement after the judgment, reference can be made to relevant provisions.Creditor's rights and debts, and enforcement casesColumn.

III. Professional analysis by Henglue Law Firm

From the practical experience of lawyers handled by our firm, the effectiveness of representing clients in second-hand housing disputes lies more in the organization of evidence and the selection of strategies, rather than a fixed proportion. Common scenarios include: the seller claiming that the contract is invalid due to the spouse's disagreement with the sale, which the court usually judges based on the rules of joint ownership registration, bona fide acquisition, and apparent agency; the buyer being sued for breach of contract due to unapproved loans, which requires distinguishing between policy adjustments and the buyer's own creditworthiness issues; and the seller selling the same house to two buyers, where the buyer who has completed the transfer of ownership sues the previous buyer for compensation. In the judicial practice of Beijing courts, support for the breaching party's loss of price difference and reasonable legal defense costs is relatively clear, but claims with insufficient evidence will also be rejected. Common pitfalls include: oral supplementary agreements not being formalized in writing; mixing the payment of deposits with down payments; and delaying the issuance of letters after discovering breaches of contract, thereby missing the opportunity for contract termination and preservation of evidence. These experiences show that rather than obsessing over percentages, it is better for professional lawyers to check the contracts and evidence item by item as early as possible, and evaluate the feasibility and cost of two paths: continuing performance and claiming compensation for breach of contract.

IV. Practical suggestions and legal basis

Action suggestions: 1. Before signing the contract, verify the ownership of the property by retrieving the real estate registration information to confirm whether there are any seizures, mortgages, or co-owners. 2. Specify in the contract the transfer deadline, payment milestones, penalty clauses, and obligations for household registration transfer. 3. Use a supervised account for payments, and retain transfer receipts and communication records. 4. Promptly send written notices upon detecting breach of contract to preserve evidence for contract termination and claim compensation. 5. Assess the costs of continuing performance and seeking compensation. Legal basis: Article 577 of the Civil Code of the People's Republic of China (effective January 1, 2021) establishes general rules for breach of contract liability. Article 584 specifies that the amount of compensation for losses should be equivalent to the damages caused by the breach of contract, including the benefits that could have been obtained after the contract was performed. Article 585 regulates the agreement on penalties for breach of contract and judicial adjustments. Articles 586 and 587 stipulate the penalty clauses for deposits.

5. Henglu Law Firm's Advice

Risk Warning: Firstly, any promise of a "success rate" does not comply with professional norms. The outcome of the case depends on the facts, evidence, and the court's determination. Secondly, the statute of limitations for such disputes is three years, calculated from the date when the right holder knows or should have known that their rights have been infringed and the date when the obligee becomes aware of the infringement. Delays will weaken the conditions for evidence collection and enforcement. Thirdly, it becomes increasingly difficult to continue performance after the house is sealed off in another case. If a breach of contract is discovered, it is necessary to sue as soon as possible and consider property preservation. Fourthly, the choice of the deposit, the breach of contract penalty, and the loss of the price difference directly affects the scope of compensation. Before making a claim, it is necessary to calculate the amount of compensation.

VI. Frequently Asked Questions

Q1: Is it guaranteed that hiring a lawyer to handle a second-hand housing lawsuit will lead to victory?

I can't make any promises. The outcome of the case depends on the contractual provisions, the evidence of performance, and the court's determination of the facts of breach of contract and the scope of losses. Any institution or individual promising a certain percentage of winning the case does not comply with professional norms. From practical experience, cases with clear ownership, complete evidence, and clear facts of contractual compliance are more likely to gain support; if the evidence is insufficient or there are breaches of contract on the part of the client, the claims may be rejected or partially rejected. It's more meaningful to truthfully disclose the case situation and rationally assess expectations before signing the contract than to pursue any verbal promises.

Q2: What evidence do I need to prepare for a second-hand housing dispute?

The main evidence includes: the house sale and purchase contract and supplementary agreement, which prove the payment milestones, the transfer deadline, and the agreement on breach of contract liability; payment receipts, loan approval and disbursement materials; online signing and filing information and the results of real estate registration inquiries, which are used to prove the ownership status and whether there is any seizure, mortgage, or secondary sale; written reminder letters and delivery certificates; WeChat chat records, call recordings, and other evidence of performance communication; and contemporaneous transaction records or appraisal reports, which are used to prove the loss of the house price difference. The evidence should be systematically organized around the facts of breach of contract and the scope of losses.

Q3: How much does it cost to litigate against a second-hand house transaction?

The fees mainly include attorney fees and litigation fees. Attorney fees are determined through negotiation based on the value of the case and the complexity of the case, with no uniform standard; litigation fees are charged in stages according to the amount of the litigation request. For cases involving property transfer or large-scale compensation, they are charged according to the standards for property cases. In the case of partial victories, the court will share the fees proportionally. If it is necessary to apply for property preservation, the preservation fees and guarantee fees will be calculated separately. It is recommended that you first let the lawyer estimate the amount you can claim and the strength of the evidence, and then evaluate the input and output to avoid blindly expanding the claims and increasing the costs.

Q4: How long does it usually take to litigate a second-hand housing dispute?

The first-instance ordinary procedure generally lasts no more than six months. Where the facts are clear and the disputes are not significant, the simple procedure can be completed within three months; if the other party appeals, the second-instance procedure will take about three months. Where appraisal, identification or preservation are involved, the period will be extended accordingly. If the other party refuses to perform after the judgment takes effect, it is also necessary to apply for enforcement, and the overall period may exceed one year. When the house is at risk of being sealed up or disposed of in another case, suing and preserving it as soon as possible can effectively shorten the actual resolution time.

Q5: What should I do first if I find that the seller has breached the contract?

The first step is to issue a written notice and collect evidence, clarifying the facts of the breach of contract and the deadline for performance; the second step is to verify the ownership status of the house to determine whether there are any obstacles to performance such as seizure, mortgage, or secondary sale; the third step is to evaluate two paths: continued performance and claim resolution, and compare which claim is more advantageous among the penalty for the deposit, the breach of contract penalty, and the loss of the price difference; the fourth step is to apply for property preservation to prevent the house from being disposed of again if necessary; and the fifth step is to entrust a lawyer to formulate a litigation plan.
