⚠️ Courts typically do not accept documents signed by ordinary attorneys or those that have not been properly forwarded.

This clarifies notary operations in litigation scenarios.

I. Why must litigation documents be notarized and transmitted?

Different legal systems in the two regions mean mainland courts cannot directly verify the authenticity of Hong Kong company documents. Unnotarized documents are deemed "formally invalid," leading to:

• Not accepted or required to supplement at the case filing stage

• Entity status not confirmed

• Invalid power of attorney; the lawyer cannot represent you.

• Evidence formed in Hong Kong is not admissible.

Whether a Hong Kong company is the plaintiff or defendant, this procedure is almost always required when proof of legal standing or authorization is needed.

II. Core Documents Requiring Notarization During Litigation

📁 1. Certificate of Legal Entity Status (Required)

• Certificate of Incorporation (CI)

• Valid Business Registration (BR)

• Latest Annual Return (NAR1) or Incorporation Form (NNC1)

• Articles of Association (required by some courts)

• Register of Directors, Register of Shareholders (as filed with the Registrar)

These documents certify the Hong Kong company's legal existence and its standing to sue or be sued.

📋 2. Board Resolution (Critical)

• A resolution must be adopted specifically for this litigation, typically including:

  • Agree to file a lawsuit / respond to a lawsuit in XX Court against XX.

  • Explicitly authorize a director or designated individual as the authorized signatory / legal representative (for this litigation).

  • Specific Mainland Lawyer Authorization (you may specify the lawyer's name and law firm)

  • Confirm signature specimen and company seal format

Resolutions must be signed by an authorized director in accordance with the company's articles of association.

📄 3. Power of Attorney (for Mainland China Lawyers)

• Specify the retained attorney's details, the scope of engagement (filing suit, responding to suits, mediation, appeals, document receipt, etc.), authority limits, and duration. Use specific language for authority; avoid vague terms like "full representation."

🆔 4. Other required documents

• Legal Representative Identity Certificate

• Director Identification (Copy of ID Card / Passport)

• Key evidence materials formed in Hong Kong (e.g., contracts, correspondence, meeting minutes). If submitted as evidence, they typically require notarization.

• If the company has changed its name, please provide a certificate of name change.

📌 Note:Requirements may vary slightly by court. Confirm the specific checklist and format requirements with your attorney before proceeding with notarization.
