What is dual authentication? I applied for immigration to France and let me handle the birth of my daughter.

Double authentication refers to the use of notarial certificate to authenticate the embassy (consulate) of the country after the consular department of the Ministry of Foreign Affairs of China or the foreign affairs offices of relevant provinces, autonomous regions and municipalities have completed the authentication procedures. This practice of handling two authentications is often called double authentication.

According to international practice, the consular certification of notarial certificate is the final signature of diplomatic and consular organs on foreign-related notarial certificate. The purpose of consular certification is to enable the notarial certificate issued by one country to be recognized by the relevant authorities of another country, so as not to affect the legal effect of the document because of doubts about the authenticity of the signature or seal on the document.

To apply for double certification of birth certificate, you need to apply for two certifications, domestic certification and foreign affairs certification.

The required materials are as follows:

The materials generally needed for domestic birth notarization are the birth certificate issued by the birth hospital, the ID card and household registration book of the students and their parents, and the parents' marriage certificate; Foreign affairs certification requires domestic notarial certificate.

The process of double authentication is as follows:

1. Go to the notary office to notarize the birth certificate: "This is to certify that xxx's father is xxx and his mother is xxx", plus one page of translation;

2. Then take this notarial certificate, go to the local foreign affairs office, stamp it, and it will say, "This is to certify that the notary xxx of this notarial certificate and her seal are not fake, and add the signature xxx".
