Foreign Company Documents for China IP Litigation: Identity, Authority and Apostilles

By Pan Jianxing · Published 21 September 2026

A foreign brand can have a strong infringement file and still lose time assembling the documents that identify the claimant and authorize its Chinese lawyer. An incorporation certificate, a director's signature and a trademark registration answer different questions. Preparing them as one coordinated file helps expose gaps before a filing deadline becomes urgent.

This guide concerns foreign companies bringing civil IP claims in mainland China. It addresses document preparation rather than the merits of infringement or jurisdiction. The legal position was checked on 21 September 2026.

Separate the company, its representative and the IP right

Start with three questions: which legal entity will sue, who can act for that entity, and why that entity has the right to enforce the particular IP? Under Article 5 of the Supreme People's Court's cross-border online filing provisions, an overseas enterprise provides both identity documents and proof that its representative can participate in litigation on its behalf.

Prepare a document map showing the registered name, incorporation jurisdiction, registration number, address and current status. Identify the record supporting the proposed signatory's authority. Depending on the company's structure and home law, relevant records might include a registry extract, constitutional documents or a corporate resolution. These are a working checklist, not a promise that one standard bundle satisfies every court.

Compare that identity with the rights records. If the Chinese trademark belongs to a holding company while the sales contracts name an operating subsidiary, record the distinction. A group relationship alone does not explain the proposed claimant's entitlement. Name changes, transfers and licences need their own documentary chain. Send these issues to counsel before commissioning translations or notarisation.

Choose the authentication route document by document

China's Ministry of Foreign Affairs confirms that the Apostille Convention took effect for China on 7 November 2023. For qualifying foreign public documents where the Convention operates between the originating state and China, an apostille replaces the consular legalisation step. It does not remove every earlier document-preparation requirement.

Check the document category, originating jurisdiction and current treaty relationship, including relevant objections or territorial application. Under Article 1 of the Convention, public documents include notarial acts and certain official certificates placed on privately signed documents. A privately signed power of attorney therefore needs an assessment of the appropriate notarial or official certification route; the company should not simply request an apostille for an unsigned template. The Convention also has exclusions, so avoid treating every overseas commercial document alike.

Where the Convention does not apply, examine the applicable consular legalisation route and any other treaty-based simplification. Keep corporate identity documents and the litigation power of attorney as separately tracked items, even if they are being processed together. Hong Kong, Macao and Taiwan documents require review under their specific mainland-use arrangements.

Make the power of attorney fit the intended action

Article 275 of the Civil Procedure Law, as amended in 2023, addresses powers of attorney sent or entrusted from abroad by foreign parties without a domicile in China. It provides for notarisation and consular authentication or the relevant treaty formalities. Read that provision together with the applicable Apostille Convention route.

Article 62 requires the authorization to specify the matters and powers entrusted. Admitting the opposing party's claim, abandoning or amending one's own claims, entering into a settlement, and bringing a counterclaim or appeal require special authorization. The business should decide which powers it intends to grant before signature. A broad English label such as “full authority” is an unreliable substitute for checking the operative wording. Counsel should also confirm whether additional procedural stages require further documents.

Keep the final signed version, its attachments, the signatory's supporting records and the authentication certificate together. Do not silently replace a page after certification. If a name, signature or corporate status changes, flag the change and establish whether a replacement document is needed.

Ask whether court-witnessed authorization is available

Article 6 of the cross-border online filing provisions allows a party that has passed identity verification to request online video witnessing when appointing a mainland lawyer. The judge, party and lawyer participate together; authorization documents signed through that process do not need the additional notarisation, authentication or transmission formalities specified there.

This is a court-managed option, not an ordinary video call with counsel. It does not eliminate the earlier company-identity and representative-authority review. Ask the receiving court about the procedure before relying on it for a deadline, and arrange language assistance where needed.

Authenticate the source without overstating the evidence

The Ministry's apostille explanation distinguishes authentication of a signature or seal from confirmation that a document's contents are true or lawful. An apostille cannot repair a missing licence, establish infringement or make an unsupported corporate statement conclusive.

Article 16 of the SPC civil evidence provisions distinguishes foreign public documentary evidence and evidence concerning status relationships. Do not import the old assumption that every overseas email or invoice must follow identical formalities. Assess each item's nature and intended use. Article 17 requires Chinese translations of foreign-language documentary evidence or explanatory material; the online filing provisions also address qualified translation for filing materials.

Maintain a filing-readiness checklist

• Match the proposed claimant to its current company records and the IP ownership or enforcement chain.
• Confirm the representative and the specific powers being granted.
• Record the agreed formalities, responsible person and remaining step for each document.
• Keep complete scans, originals, attachments and translations linked by stable file names.
• Track document preparation separately from submission, court acceptance and later evidential assessment.

For a China IP litigation preparation review, start with a non-confidential summary identifying the claimant's jurisdiction, the rights involved and the relevant deadline. Sensitive corporate records can follow through an agreed channel after the initial conflict and scope check.
