Why do we need to dothe consul's signature The purpose of the consular signature is to verify the authenticity of the document to the foreign institution that uses the document, so as to avoid affecting the use of the document because it suspects whether the signature or seal is true. For example, if the domestic notary office issues a birth notarization/book, if the party concerned does not ly for a consular signature and seal directly to country A, the petent authority of country A cannot verify the authenticity of this document, so it will refuse to accept it, and the authority of country A will require the party The documents will be confirmed by the Embassy (Consulate) of A in China. And the embassy (consulate) of country A in China does not have the signature or seal of the domestic notary office of China, and it is difficult to verify the authenticity of the document itself. Therefore, it will require the document to be signed by the Chinese official/party organization to certify the relevant document certificate unit The seal and official signature are true, and then the embassy (consulate) of country A in China reconfirms that the seal and signature of the Chinese official/party organization are true. Only then will the petent authority of country A accept this document.
