We ensure the process is handled smoothly, accurately, and in line with required standards.

Consular Legalization

Consular legalization is required when Chinese documents are used in countries that are not members of the Hague Apostille Convention. We assist with the full process, including notarization, authentication, and embassy legalization for both personal and corporate documents.

Apostille

We provide Apostille services in Mainland China for a wide range of documents. Both personal and corporate documents can be processed, including certificates, academic records, and company materials required for use in Hague Convention member countries.

International Document Legalization Made Simple

When documents issued in China need to be used abroad, they often must go through a formal authentication process so that foreign authorities can recognize their legal validity. WELLTHINK Translation provides reliable legalization services in China, helping individuals and companies prepare documents for international use smoothly and efficiently.

Our legalization services cover two main types of document authentication: Apostille certification and consular legalization. Apostille certification is used for countries that are members of the Hague Apostille Convention. Through the Apostille process, public documents issued in China—such as academic certificates, birth or marriage certificates, powers of attorney, and corporate documents—can be recognized by authorities in other member countries without additional embassy legalization.

For countries that are not members of the Hague Convention, documents usually require consular legalization. This process typically involves notarization, authentication by the relevant authorities, and legalization by the embassy or consulate of the destination country. WELLTHINK Translation assists clients with the preparation of documents and coordination throughout the legalization procedure.

In many cases, documents must also be translated before submission. Our team provides professional legal translation services to ensure that documents meet the language and formatting requirements of foreign authorities.

With extensive experience handling document legalization and authentication in China, WELLTHINK Translation helps clients navigate complex procedures and ensures that documents are properly prepared for international use.

Although AI technology has developed rapidly in recent years, it still cannot fully handle complex language situations, especially in legal or high-stakes documents. Our translators therefore rely primarily on professional human translation and review, ensuring accurate terminology and consistent language. AI tools may be used as supporting tools, but the core work is always completed by experienced translators.
