Essential for Cross-Border Litigation Authorization: 2026 Latest Process & Fee Breakdown

📅 2026 7 📍 Both China and the US are members of the Hague Convention ⏱ Read time: 7 minutes

😰 Are you experiencing these issues?

Living in the U.S. but facing a lawsuit back home? Divorce, property disputes, contract breaches, inheritance issues...The court filing window coldly stated: "Please provide a notarized and authenticated power of attorney, or the case cannot be filed."

You searched through your emails and found the power of attorney you signed with a lawyer three years ago, but the domestic court informed you"Authentication has expired, and the U.S. no longer uses consular authentication."Start over from scratch.

Or, as a domestic lawyer representing a U.S. client, with the deadline for submitting evidence approaching day by day, yet the client remains unclearWho do I contact for notarization? Which department handles certification? What are the costs, and how long does it take to receive the documents?Made countless calls, but the more I asked, the more confused I got.

——这种The court date is approaching, but the documents are stuck halfway across the world.We get the anxiety.It's not your fault. Cross-border litigation rules are just too complicated.

Why get 01 apostille certification?

First, clarify a core legal issue:你在美国签署的授权委托书，是一份在美国境内产生的私人文书。中国法院要确认这份文件的Authenticity— Is this signature personally made by you? Did you have full civil capacity at the time of signing? Chinese courts cannot directly verify these details.

In the past, using US documents in China required going through "US notarization → State Secretary authentication → US Department of State authentication → Chinese Embassy/Consulate authentication."Level 4 CertificationChains, taking weeks or even months.

🔑 Major Changes:2023年11月7日，《取消外国公文书认证要求的公约》（海牙公约）正式在中国生效。美国自1981年起已是该公约成员国。自此，Notarial documents exchanged between China and the U.S. only require an Apostille to be valid in both countries; consular legalization by embassies or consulates is no longer needed.

This means:"Level 4 certification" simplified to "Level 2 certification"US notarization plus Hague Apostille certification from the Secretary of State or U.S. Department of State enables direct use in Chinese courts.

Who needs to apply?This scenario is unavoidable:

• ✅ U.S. citizens or green card holders: Hire a Chinese lawyer to represent you in domestic civil litigation (divorce, debt disputes, contract disputes, etc.)

• ✅ For Chinese nationals in the U.S. who cannot return home and have entrusted relatives or friends to handle domestic litigation matters on their behalf

• ✅ U.S. companies as plaintiffs or defendants, appointing Chinese lawyers to represent them in litigation in China

• ✅ 跨境继承案件中，委托国内律师处理遗产诉讼

• Power of Attorney for Recognition and Enforcement of U.S. Court Judgments in China

💡 One-sentence summary:A U.S. power of attorney without Hague Apostille is "a piece of paper" in Chinese courts—立案不受理、开庭不认人、判决不执行。

How to get 02? The latest 3-step process

⚠️ Core Principle: Notarize first, then authenticate. The order must not be reversed!State and federal documents must be distinguished based on their nature and submitted to the respective agencies.

1 Draft Power of Attorney + US Notarization

🔹 Draft Power of Attorney:We recommend that a domestic attorney draft the Power of Attorney template based on litigation requirements, clearly specifying key clauses such as the scope of entrusted matters, authority limits (general or special authorization), and the duration of the mandate. For litigation representation, we suggest using...Special Authorization，明确列出“代为起诉、应诉、调解、签收法律文书”等具体权限。

🔹 公证（Notarization）：The principal must appear in person before a U.S. licensed Notary Public with valid identification (e.g., passport, driver's license) to sign the power of attorney. The notary will verify identity and then affix their signature and seal.

💡 As of 2026 in 4, 48 U.S. states recognize the legal validity of remote notarization, which can be completed via state-approved video platforms for signing and witnessing.

📌 Notary fees: Approximately $100–$300 (varies by location and notary)

2 Secretary of State Authentication / US Department of State Apostille

🔹 State-level documents (most powers of attorney fall under this category):Submit the notarized power of attorney to the issuing state'sSecretary of State(Secretary of State) to process the Apostille, verifying the authenticity of the notary's signature.

🔹 Federal-level file:If the document is issued by a federal agency or federal court, submit toU.S. Department of State Certification OfficeApply for an Apostille.

💡 Some states (e.g., California, New York, Maryland) have launched expedited state-level Apostille services, with certificates issued in as little as 24 hours.

📌 State Certification Fee: $100–$350/doc

3 Translation + Submit to Chinese Court

🔹 Chinese translation:海牙认证完成后，需将整套文件翻译成中文。2026年起，若文书本身为英文，中方使用单位仅需提供加盖翻译公司公章的中文译本，No separate translation notarization is required.。

🔹 Submit to Court:Submit the original notarized power of attorney along with a Chinese translation to the accepting court in China. Some courts may require proof of the translation agency's qualifications; we recommend confirming this requirement with the accepting court in advance.

💡 Each Apostille is assigned a unique file number and can be verified online in both English and Chinese.

📌 Translation fee: Varies by page count and language, typically ¥200–¥800/document

🚀 Efficiency Tips:Let the domestic lawyer handle the power of attorney first.Content finalized——Key clauses such as the mandate, scope of authority, and duration must be exact. Verify everything before notarization and legalization; once completed, any changes require restarting the entire process.

04 Litigation Scenario Special Notice

Courts are increasingly strict in form review of foreign documents.

Pursuant to Article 264 of the Civil Procedure Law of the People's Republic of China, a power of attorney submitted by or mailed from abroad by a foreigner, stateless person, foreign enterprise, or organization that has no domicile within the territory of the People's Republic of China shall beMust be certified by the notary public of the country where it is located and authenticated by the Chinese embassy or consulate in that country, or satisfy the certification procedures stipulated in relevant treaties concluded between China and that country.。

Since both China and the United States are members of the Hague Convention,A Hague Apostille is deemed to satisfy the aforementioned "authentication requirements."，无需再经中国驻美使领馆认证。
