In the context of growing globalization, the use of Vietnamese documents in the United Kingdom for purposes such as studying, working, immigrating, or conducting commercial transactions is essential. However, for these documents to be legally recognized in the UK, you need to go through the process of consular legalization.
The full-package UK consular legalization service at No.1 Translation was created to resolve difficulties, helping you save time, effort, and costs. The article below provides detailed information about the UK consular legalization procedure as well as the latest 2025 updated pricing. Let’s explore!
Consular legalization and consular certification are two important steps in the process of validating documents between two countries to ensure that papers and documents are recognized and legally used abroad.
UK consular certification is an administrative procedure carried out at the Legalisation Office – the Foreign, Commonwealth & Development Office (FCDO), the competent diplomatic authority of the United Kingdom.
The purpose of this procedure is to verify the signature, seal, and title on documents or papers issued in the UK so that these documents can be legally used in another country.
For example, if you have an important document such as a birth certificate issued in the UK and wish to use it in Vietnam, the first step is to carry out consular certification at the FCO. This procedure serves to verify the accuracy and legality of the information on the document.

Consular legalization is the next step after consular certification, carried out by the diplomatic authority of the country where the document will be used. Specifically, the competent Vietnamese diplomatic mission, such as the Embassy or Consulate General of Vietnam in the UK, will confirm the authenticity of the seal, signature, and title of the UK diplomatic officer on the consular-certified document.
Conversely, for documents issued in Vietnam that are intended for use in the UK, the consular legalization procedure will be carried out by the UK Embassy or Consulate General in Vietnam.
