[Direct answer]In the Beijing area, responses made after the expiration of the commitment period generally do not constitute valid commitments, and the contract cannot be established on this basis. According to Article 486 of the Civil Code of the People's Republic of China (effective January 1, 2021), if the offeree sends a commitment after the expiration of the commitment period, unless the offeror promptly notifies the offeree that the commitment is valid, it shall be regarded as a new offer; Article 487 further distinguishes between "late arrival" and "overdue arrival". If the commitment is sent within the time limit but arrives after the deadline, the offeror shall promptly notify the offeree, otherwise it shall be deemed valid. Key time limits: The commitment must arrive within the time limit specified in the offer. If no time limit is specified, it shall arrive within a reasonable time limit. Action guidance: Upon receiving a response that arrives after the deadline, the offeree should promptly confirm in writing whether to accept it to avoid being deemed to have made a commitment by remaining silent.

I. Problem Background and Typical Scenarios

In commercial negotiations, the risk of promises expiring is the most easily overlooked legal risk. Typical scenarios include: the buyer delays signing the contract, and the seller has already prepared the goods or entered into another contract; the electronic offer sets a short commitment period, and the email arrives late due to time differences or system delays; in long-term cooperation, both parties act tacitly by "implicitly renewing the contract", and the other party's late statement triggers a dispute over whether the contract is established; the bid under the tender or framework agreement is "accepted" after it has expired. All these situations point to the same problem: whether an expired response can still lock in the transaction. For related rules, please refer toLegal services for corporate commercial and contract disputes.

II. Key points of dispute

The controversy focuses on three points. Firstly, the distinction between late and overdue commitments: a commitment issued after the deadline is considered an overdue offer, which is, in principle, a new offer; a commitment issued within the deadline but delivered late, if the offeror fails to deny it in time, can be deemed valid, with different legal consequences for the two cases. Secondly, the offeror's obligation to "notify in a timely manner": for a late commitment, if the offeror does not accept it, they must notify within a reasonable time, and silence may be regarded as the commitment being valid. Thirdly, the determination of a reasonable deadline: when no deadline is agreed upon, it shall be determined based on the transaction practices, the content of the offer, and the communication method. For remote transactions, the deadline is shorter. In the judicial practice of Beijing, the court usually determines it based on the objective arrival time and the transaction background in a comprehensive manner.

A contractual dispute over cooperative operation handled by Attorney Shang Jiangpeng highlights the importance of evidence management during the contract formation and performance stages. On July 14, 2023, Liu Shufen signed a cooperative operation contract with Company A (a one-person limited liability company with 100% shares held by Wang Xiaochen) and paid a cooperative operation lease fee of 168,000 yuan to obtain a 15-year cooperative operation right to a property in Fengtai District. The contract stipulated that the operating income would be paid annually, and the right to use the property could be exercised if the payment was overdue for more than 30 days. After Company A paid seven quarters of income, it stopped making payments and went through liquidation starting from April 15, 2025. Liu Shufen entrusted Attorney Shang Jiangpeng to litigate the case. The attorney reviewed the contract, financial records, business registration files, and liquidation materials, arguing that Company A breached the contract fundamentally and the contract should be terminated. He also sought to hold the sole shareholder, Wang Xiaochen, liable for joint and several repayment. The court confirmed that the contract was terminated on March 20, 2026, and ordered Wang Xiaochen to return 168,000 yuan and pay the outstanding income and breach of contract damages. Although this case focused on performance and breach of contract, its premise was that the contract was legally established and the commitments were valid—if there were time-overrun defects in the commitment stage, the subsequent rights and obligations would be completely different. This case was handled by Beijing Henglu Law Firm.Shang JiangpengAttorney (Practice Certificate No.: 11101202310580738, subject to the certificate issued by the judicial administrative organ) acting as an agent.

5. Hengluo Law Firm's Reminder

The greatest risk of overdue commitments is "believing that the contract has been established". Silence or subsequent performance may be interpreted as acceptance, leading to passive performance or compensation. It is recommended that enterprises include commitment deadlines and overdue handling clauses in the negotiation template, and appoint dedicated personnel to track the arrival time. When handling similar contract matters in the Beijing area, they can refer to the relevant provisions of the Beijing Municipal Law on Contracts for Construction Projects.Beijing Henglu Law FirmUnder the assistance of professional lawyers, the offer and commitment chain is reviewed, and the establishment time and scope of effectiveness are put in writing, thus reducing the burden of proof in the performance stage.

VI. Frequently Asked Questions

Q1: If the promise has expired, can the other party still accept it retroactively?

Yes. In principle, a late commitment becomes a new offer. If the original offeror promptly notifies the offeree that the commitment is valid, the contract can still be established; for commitments sent within the time limit but arrived late, the offeror's failure to promptly deny them shall be deemed valid. The key lies in whether the offeror makes a clear expression of intent within a reasonable time. Silence or delay may lead to unfavorable presumptions. The outcome of the case depends on the content of the notification and the evidence, and lawyers cannot unilaterally guarantee the determination of effectiveness.

Q2: What evidence should be prepared for disputes over overdue commitments?

The core evidence includes: the offer text and the time limit, delivery method, and sending records contained therein; the timestamp, email header information, and system logs of the offeree's response; the parties' previous transaction habits and communication records; and evidence of the offeror's response after receiving a late response. The focus is on proving the time of the offer's issuance and arrival, whether it exceeds the time limit, and whether the offeror promptly notified the offeree. Organizing the evidence chronologically will facilitate the court's determination.

Q3: How much does it cost to hire a lawyer to handle such contract disputes?

The attorney's fees are determined by the law firm based on the amount of the dispute, the complexity of the evidence, and the stage of the litigation, without a unified government pricing. The litigation fees are paid in accordance with the "Measures for the Payment of Litigation Fees" (State Council Decree No. 481, implemented on April 1, 2007), with the amount of the litigation request as the base for cumulative payment in stages. Mediation or summary procedures are subject to a 50% reduction. Before entrusting a lawyer, it is recommended to calculate the amount of the dispute and the cost of protecting rights, and to evaluate the effectiveness of the offer and promise as well as the subsequent performance claims together.

Q4: How long does it usually take to resolve disputes over overdue commitments?

The consultation or sending a letter to confirm can be clarified within a few days; the first-instance summary procedure of litigation will be concluded within three months, and the ordinary procedure within six months. The announcement of service or appraisal may prolong the period. If it involves the termination of the contract and the compensation for breach of contract at the same time, the trial will be conducted together with the main case. The overall period ranges from several weeks to more than a year, depending on whether the two parties have a fierce dispute over the establishment time point.

Q5: If the promise is found to be overdue, what should the enterprise do next?

Three-step process: First, immediately check the offer deadline and the response arrival time to determine whether it is overdue or late. Second, if you do not accept the offer, you should explicitly deny it in writing and explain the reasons. Silence does not constitute acceptance. If you accept the offer, send a confirmation in a timely manner to avoid regrets. Third, if a dispute arises due to partial performance, fix the evidence of performance and consult a lawyer to assess whether the contract has been established and determine the liability for breach of contract or breach of fiduciary duty. It is safest to put your position in writing.
