Foreign authentication, also known as consular authentication or diplomatic authentication. It refers to the diplomatic and consular authorities of a country certifying the authenticity of the final seal or signature of a notarized document. The following is a detailed explanation about foreign-related certification:

1、 The purpose of foreign certification

To ensure that the notarization and authentication of a country have equal legal effect in other countries, thereby ensuring that documents can be accepted and recognized when used outside the country.

2、 The process of foreign certification

For the use of Chinese public certificates outside the territory, it is necessary to first obtain certification from Chinese diplomatic or consular authorities that the seal on the notarized document is authentic.

Next, the foreign embassy or consulate in China needs to verify the authenticity of the authentication from our diplomatic and consular departments before it can take effect in that country.

Similarly, foreign notarized documents used within the territory of China also need to be authenticated by the foreign diplomatic and consular departments first, and then verified by the Chinese embassy or consulate in that country.

3、 The authority responsible for handling foreign-related certification

In China, the agencies responsible for handling foreign-related certification services mainly include the Consular Department of the Ministry of Foreign Affairs, the foreign affairs offices of the people's governments of various provinces, municipalities, autonomous regions, and municipalities directly under the central government, foreign embassies, consulates, and agencies.
