Observation
In a China-related commercial dispute, the decisive issue is often not whether the business story sounds credible but whether the claimant can prove the contract, breach, loss and identity of the responsible entity. Building a China commercial dispute evidence file should begin before filing: preserve original records, map the people and companies involved, maintain translations, and choose a forum and evidence strategy that fit the transaction.
Start with the elements you must prove
The Civil Procedure Law of the People’s Republic of China, in its 2023 revision effective 1 January 2024, applies to civil litigation in China and contains rules on jurisdiction, evidence, preservation, foreign-related procedure and enforcement. The Supreme People’s Court’s Provisions on Evidence in Civil Litigation require the court to assess relevance, authenticity and legality rather than simply count documents.
Make a claim matrix: contract formation, performance, breach, causation, loss, mitigation, authority, limitation and requested relief. For each element, identify the primary document, the witness or expert, the likely challenge and the backup evidence. This prevents a large data room from obscuring a missing purchase order, acceptance record or proof that the defendant is the correct legal person.
1. Preserve native electronic records
Email, messaging applications, platform logs, cloud documents, ERP entries, photographs and electronic signatures can be important evidence. The evidence provisions direct courts to consider the reliability of the hardware and software environment, the method used to preserve and extract the data, whether it arose in ordinary business activity and whether a neutral platform or agreed process kept it.
Preserve the native file where possible, not only a screenshot. Export a complete conversation with sender, recipient, account identifier, date, time zone, attachments and surrounding messages. Keep the audit trail for electronic signatures, document versions, access logs and file hashes where available. Record who collected the material and when. Do not edit or rename an original in a way that obscures its provenance.
2. Prove identity, authority and the transaction chain
Match the contract party to the Chinese registered name, unified social credit code, invoice issuer, bank-account holder and the entity that delivered goods or services. A group email domain or factory brand may not be the legal defendant. Collect business licenses, powers of attorney, board or shareholder approvals, company-seal records, platform-account information and evidence of performance.
Where authority is disputed, conduct after signing can matter, but do not assume that partial performance cures every defect. Keep the original proposal, order, contract, specifications, amendments and acceptance documents in chronological form. Identify which version controls and who approved each change.
3. Use translations without losing the original
For an overseas business, a bilingual evidence file is practical, but the Chinese original should remain the reference record. Use a competent translator for material documents and preserve a translation certificate or statement of method if needed. Note ambiguities rather than silently choosing the interpretation most favorable to your position.
Check names, company codes, amounts, dates, units, Incoterms, technical tolerances and defined terms line by line. A mistranslated Chinese company name can lead to the wrong defendant; a translated “acceptance” term can conceal a different contractual standard.
4. Preserve evidence before a dispute hardens
If a product, machine, site condition or server log may change, consider a preservation request, notarization, independent inspection or other lawful method suited to the issue. The court may order evidence preservation where evidence may be lost or difficult to obtain later. A preservation plan should be proportionate and should respect confidentiality, data-security and third-party rights.
Send a carefully drafted preservation notice to employees, affiliates, suppliers and platforms that control relevant records. Identify the subject matter and date range, but avoid instructing people to create retrospective explanations. Preserve both favorable and unfavorable records; credibility can be damaged if the collection appears selective.
5. Link evidence to loss and mitigation
Commercial damages need more than an invoice total. Collect payment records, replacement purchases, inspection costs, freight, storage, repair, resale, customer claims and internal calculations. Show the contractual basis, causation and steps taken to reduce loss. Separate direct loss, consequential loss, agreed damages and costs that may be excluded or limited by the contract.
Maintain a loss ledger that links each amount to a dated source document. Explain foreign-currency conversion, tax treatment, credits, refunds and recovered amounts. The best evidence file makes the calculation reproducible by someone who was not involved in the transaction.
6. Consider online litigation and neutral-platform evidence
The People’s Courts Online Litigation Rules, issued by the Supreme People’s Court and effective 1 August 2021, address online filing, service, evidence exchange and the treatment of electronic materials. They do not make every online record automatically authentic. The parties still need to establish the source, integrity and relevance of the material and comply with the court’s directions.
Where a neutral platform stores the record, request a formal export or confirmation rather than relying only on a user’s screenshot. Keep the terms of service and the account-registration material that shows who controlled the account at the relevant time.
Practical evidence checklist
- Create a claim-and-proof matrix before collecting large volumes of data.
- Preserve Chinese originals, native electronic files and complete metadata.
- Identify the legal entity, signatory, seal, account and performance provider.
- Keep a chronological transaction file with version control.
- Use reliable translations and record unresolved language issues.
- Preserve changing physical or digital evidence before testing or alteration.
- Build a source-linked loss ledger and mitigation record.
- Check forum, service, translation, legalization and enforcement requirements early.
Common misconceptions and limits
- “A screenshot is the evidence.” It may show content but not source, completeness or authorship.
- “A signed PDF proves every term.” Later amendments, attachments and authority may still be disputed.
- “More documents mean a stronger case.” Relevance, integrity and a clear claim map matter more than volume.
- “A foreign judgment will be easy to enforce.” Recognition and enforcement depend on applicable law, treaty or reciprocal practice and the debtor’s assets.
