Apostille vs. Embassy legalisation for Vietnam
A plain apostille issued in Sunderland for use in Vietnam is not yet accepted there. Anyone searching for a Sunderland apostille for Vietnam before 11 September 2026 needs the fuller route instead: the FCDO's check followed by a further stamp from Vietnam's own embassy or consulate. That second stage is what currently finishes the process for use in Vietnam, not the FCDO's part on its own, however carefully it was carried out.
This is not a permanent state of affairs. Vietnam has already joined the Hague Convention, and once its accession takes effect an apostille from United Kingdom to Vietnam will replace the embassy stage entirely. Until that date arrives, though, the embassy stage stays mandatory, and skipping it produces an unfinished document regardless of how correctly the FCDO's part was carried out beforehand.
The Sunderland → Vietnam route step by step
The FCDO Legalisation Office, PO Box 6255, Milton Keynes MK10 1XX, is where every document starts, working entirely by post with no counter to visit in Sunderland or anywhere else. It confirms the signature or seal on the underlying paper is genuine before the document moves on to the next stage of the route.
Today, that next stage is Vietnam's own embassy or consulate, which reviews the FCDO's work and adds a further legalisation stamp before the document is finished. Where the paper is a birth, marriage or death certificate, Sunderland Registration Service, City Hall, Plater Way, Sunderland SR1 3AA, can supply a fresh certified copy to send through this route instead of a family's only original.
Vietnam's Hague status & what it means
Vietnam's accession to the Hague Convention is dated 2026, but it does not enter into force until 11 September 2026. Before that date, an apostille is not yet accepted for Vietnam, and the embassy stage described above remains the route every document has to take, whatever category of paper is involved.
From 11 September 2026, once the accession takes effect, a single apostille certificate will replace the embassy stage for documents headed to Vietnam. That is a future change, not the current position — nothing about today's route shortens until that date has actually passed, so planning around the embassy stage remains the safe approach for now.
Destination-specific requirements
Vietnamese authorities are the ones who decide what a foreign document needs before it is recognised, and until 11 September 2026 that decision is the two-stage route: FCDO authentication, then embassy legalisation. What you need for an apostille for Vietnam right now is really this fuller process, whatever the eventual single-stage route will look like once it opens up on that date.
The same rule applies to academic transcripts, commercial contracts and personal certificates alike while the present arrangement holds. Nothing about the kind of paper changes the sequence, and nothing shortens it before the calendar reaches next September, so anyone preparing any of these items now should budget for both parts of the journey rather than assume the shorter one already applies.
Cost & timing for this route
The FCDO charges £45 for the standard postal service, or £40 for registered businesses using the quicker next-day option. Vietnam's mission then sets its own separate fee for the closing stamp, on top of whatever the FCDO has already charged, and that second charge will disappear once 11 September 2026 arrives and a single certificate is enough.
Standard turnaround through the FCDO runs up to 25 working days, plus postage, with the next working day route reserved for registered businesses. Because the embassy stage still applies for now, its own timeline is added after that figure rather than replacing it, so document legalisation for Vietnam currently takes longer than a single apostille stage would once the accession date has passed.
