Evidence in China civil litigation should be collected, preserved, translated and organized before a foreign claimant files its case. A strong contract claim can fail when the claimant cannot prove the correct defendant, performance, breach, causation or loss. This China litigation evidence checklist helps US and European companies build a usable case file for counsel, settlement and court.
Why evidence preparation starts before filing
Chinese civil proceedings require parties to support their factual assertions with evidence. Waiting until a hearing creates avoidable risk: staff leave, chat histories disappear, website content changes and original records become difficult to locate. Early preparation also reveals weaknesses that may affect the requested relief, preservation application or settlement value.
Build an issue-based evidence map
Do not simply send counsel a large folder. Create a table linking each required fact to its supporting evidence and expected defense. Typical issues include:
- the parties’ registered identities and authority to contract;
- formation, governing terms and amendments;
- your own performance and the other party’s breach;
- notices, cure periods and termination;
- amounts paid, delivered, rejected or unpaid;
- causation, mitigation and loss;
- jurisdiction, limitation and recoverable assets.
Core evidence checklist for a commercial case
Contracts and authority
Preserve every signed version, schedule, purchase order and amendment. Retain the signature and seal pages, electronic-signature audit trail and internal approval record. Match the Chinese registered entity to business-license information and payment details.
Performance records
Collect orders, production records, delivery receipts, bills of lading, warehouse records, acceptance certificates, service reports and inspection documents. Build a chronology showing what each party was required to do and what occurred.
Payment and accounting records
Keep bank transfer confirmations, invoices, account statements, credit notes and an explanation of the loss calculation. Reconcile accounting entries to the contractual milestones and the bank recipient.
Communications and electronic evidence
Preserve complete email threads and relevant messaging histories, including sender, date, attachments and surrounding context. Screenshots alone may omit authenticity information. Export or preserve native files where possible, and record who collected them and when.
Defect and damages evidence
Retain samples, photographs, videos, inspection reports, expert materials, customer complaints and disposal records. Document mitigation steps and explain how each claimed loss follows from the breach.
Foreign-language documents and overseas evidence
The official Supreme People’s Court resource on the Civil Procedure Law evidence rules states that a Chinese translation must accompany foreign-language documentary evidence. Translation quality matters because inconsistent names, dates or technical terms can change the meaning of the proof.
Documents created outside China may require additional formalities depending on their type and purpose. Ask counsel to identify the current requirements early, particularly for corporate status, powers of attorney, public records and witness materials.
Evidence preservation when proof may disappear
If evidence may be destroyed, lost or difficult to obtain later, a party may consider applying for evidence preservation. The application should identify the evidence, urgency, relevance and requested measure. A litigation lawyer should also evaluate notarization or other lawful preservation methods for changing online content and electronic records.
Cross-examination and authenticity
Evidence must survive scrutiny. For each item, anticipate objections concerning authenticity, legality, relevance and probative value. Keep originals and explain the chain from creation to production. Do not alter files or reconstruct missing evidence without a transparent explanation.
Applicable law can also require proof
Foreign-related disputes may raise a choice-of-law question. China’s official Law Applicable to Foreign-Related Civil Relationships addresses how applicable law is determined. Where parties choose foreign law, the party may need to provide that law. The Supreme People’s Court also issued a current interpretation on ascertainment of foreign law, effective from 2024.
Illustrative case: messages showed breach but not loss
This is an anonymized composite example based on common commercial litigation files; it is not a reported judgment.
A US distributor had extensive messages in which a supplier admitted delay. The initial file, however, did not connect the delay to the damages claimed. Counsel created an issue map linking the contract deadline, delivery documents, downstream customer notices, mitigation purchases and accounting records. Gaps in the damages calculation were identified before filing, allowing the client to narrow the claim and negotiate from a better-supported position.
Practical evidence handover format
- Create a one-page chronology.
- Number each document consistently.
- Keep originals and native electronic files separate from working copies.
- Provide a bilingual name list for parties, people and products.
- Link each document to the fact it proves.
- Mark missing evidence, custodians and preservation risks.
