[Direct answer]In the Beijing area, the lack of a signed document does not mean it cannot be used as evidence. The key lies in forming a complete chain of evidence. Project changes should be confirmed in writing by the employer or the supervisor, but in practice, there are often situations of oral instructions and failure to sign the document afterwards. At this time, according to Article 543 of the Civil Code of the People's Republic of China on the consultation of contract amendments and evidence rules, other evidence can be used to restore the facts of the changes: correspondence with the employer's instructions, meeting minutes and drawing review records, WeChat and emails, supervisor's logs and on-site inspection records, construction logs and image materials, materials and equipment arrival records, and the employer's acceptance of the results of the changes (such as acceptance according to the post-change status, payment or use). According to Article 20 of the Interpretation of the Supreme People's Court on Legal Issues Applicable to the Trials of Construction Contract Disputes, if the parties have disputes over the project quantity, it shall be confirmed according to the written documents such as visas formed during the construction process, and other evidence may also be comprehensively identified. If the evidence is insufficient, it may be difficult to claim the project payment for the amended part.

1. Problem background and typical scenarios

During the construction process, the client verbally requested changes in construction methods, additional work, and material substitutions, but failed to sign the change orders after the work was completed. When it came to settlement, the client simply said, "It's not in the contract, so I don't recognize it," leaving the contractor in a passive position. In construction project settlements in the Beijing area, proving unsigned changes is a frequent and challenging issue. Whether indirect evidence can be used to reconstruct the facts directly determines whether the contractor can receive the corresponding project payments.

III. Professional analysis by Henglue Law Firm

The first layer: Prioritize facts. The essence of the dispute over changes is whether changes have occurred and the extent of those changes. As long as the facts can be restored with evidence, even without a visa, the claim may still be supported. The court usually evaluates the case from three aspects: instructions, implementation, and results. The second layer: Types of available evidence. Contractors' or supervisors' correspondence and instructions, meeting minutes and drawing review records, WeChat and email communications, supervision logs and on-site inspection records, construction logs and concealed works acceptance records, material and equipment arrival and usage records, and on-site video materials can all serve as corroborating evidence. The third layer: Acceptance of changes. If the contractor organizes acceptance, disburses funds, or puts the changed results into use, or demonstrates acceptance of the changes through other actions, this constitutes important supporting evidence for the changes. In practice, this is often used as a basis for implied approval. The fourth layer: Risks of insufficient evidence. If there are only contractors' unilateral statements or self-made records without any corroborating evidence, the changed parts may not be supported. Therefore, it is crucial to document changes in real time during the construction process and obtain written confirmations promptly after the fact. Related disputes can be resolved through legal means.Property sales and construction projectsOverall service processing.

IV. Practical suggestions and legal basis

The first step is to ensure that written visas are issued simultaneously with any changes, and oral instructions are promptly confirmed in writing. The second step involves systematically collecting correspondence, memoranda, chat records, supervision and construction logs, and video materials. The third step involves preserving records of the arrival and use of materials and equipment to prove that the changes have actually been implemented. The fourth step involves organizing the contractor's acceptance, payment, and usage behavior to establish evidence of their acceptance of the changed results. The fifth step involves listing the changes and drawings, measurement records, and other relevant materials during settlement, and, if necessary, applying for an engineering cost appraisal to determine the price of the changes. Main legal basis: - Article 543, 510, and 799 of the Civil Code of the People's Republic of China; - Article 20 of the Interpretation of the Supreme People's Court on Legal Issues Applicable to the Trials of Construction Contract Disputes; - Provisions on the comprehensive identification of documentary evidence in the Civil Procedure Law of the People's Republic of China; - Specific applications shall be subject to the currently effective regulations.

5. Henglue Law Firm's Reminder

There are three key points regarding changes without signatures: Whether there is a signature is not the only criterion; the key issue is whether the changes can be restored to their original state. All relevant documents, including letters, minutes, chat records, supervision and construction logs, and video materials, should be collected. The acts of the employer's acceptance, payment, and use of the project can be deemed as tacit approval, and it is necessary to promptly supplement the signature and leave a record.

VI. Frequently Asked Questions

Q1: If the amendment hasn't been signed, will I definitely not be able to get the money?

Not necessarily. If the changes can be substantiated by evidence such as letters, minutes, chat records, supervision and construction logs, and images, they may still be supported.

Q2: Which evidence is the most convincing?

The instructions and letters from the employer or the supervisor, the minutes of meetings and the review records of drawings, the supervision logs and the on-site inspection records, the records of materials and equipment entering the site, and the on-site video materials.

Q3: Does the client's acceptance and use of the product constitute approval?

It is an important piece of evidence. Actions such as accepting the change, making payments, or putting it into use after the change can serve as the basis for presumed approval, strengthening the proof of the change's factuality.

Q4: Is it okay to only keep the construction logs that I've recorded myself?

The evidence is relatively weak and needs to be corroborated by other evidence; if there is only one piece of evidence without corroborating evidence, the changes made may not be supported.

Q5: What should I do now to make up for it?

Please apply for a new visa or obtain written confirmation as soon as possible. At the same time, the system will file the above-mentioned indirect evidence, and it will be listed accordingly during the settlement. If necessary, apply for a cost appraisal.
