Guinea's Hague status & what it means
Guinea is not a Hague Convention member, and that single fact changes the whole shape of this process. For most destinations on this list, one certificate from a UK authority is the end of the government-side task; for Guinea, it is only the first of two steps, because a Guinean office has no treaty basis for taking a UK certificate at face value on its own.
This is not a formality that will change with more paperwork or a stronger request — it follows from Guinea sitting outside the Convention altogether. A UK record intended for Guinea needs that country's diplomatic mission to add a further sign-off before a Guinean authority will act on it, regardless of how the underlying paper was prepared.
Apostille vs. Embassy legalisation for Guinea
Two different routes exist for making a foreign paper count, and Guinea sits firmly on the older one. A single certificate — the shortcut available to Hague member countries — is not accepted for Guinea; document legalisation for Guinea instead runs on the longer pattern: a UK check first, then a further sign-off from the Guinean embassy itself.
An apostille issued in London for use in Guinea, in the strict sense of that single-stage certificate, is simply the wrong tool for this particular destination, however standard that same certificate is for most other countries on this list. Treating the two routes as interchangeable is the error that sends a bundle bouncing back across the desk it was just handed to, wasting weeks rather than saving them.
The London → Guinea route step by step
Everything still starts with the paper itself: a genuine original, or a certified copy where the original needs to stay with you. A trade contract, a mining licence, a company filing or a power of attorney tied to commercial dealings in Guinea is a common reason someone in London begins this longer route.
From there, the FCDO Legalisation Office carries out the first check, working entirely by post with no London desk involved at any stage. That check on its own is not the certificate used for Hague member destinations, and the document still has a second step ahead of it once this first one is complete.
What finishes the process is a separate sign-off from Guinea's diplomatic mission, arranged directly once the UK-side paperwork is back in hand. That closing stage sits outside the FCDO's remit entirely, on a different timeline and at a different cost, set by the mission rather than by Milton Keynes.
Cost & timing for this route
The FCDO's service — covering both the certificate it issues for Hague destinations and the related UK-side check used here — costs £45 per document by standard post, or £40 per document on the next-day service for a registered business, with results back in up to 25 working days plus postage.
That window covers the UK leg only. Guinea's embassy sets a separate charge and a separate wait for the closing step, unrelated to the FCDO's figures, so a sender should treat the two legs as distinct entries on a calendar rather than one combined estimate. A business deadline in Guinea is best planned around whichever leg turns out slower, not around the FCDO's 25 days alone.
Destination-specific requirements
Because Guinea's embassy carries out the decisive second check, its exact demands — the paper list, the charge, the current wait — are not something the FCDO's process fixes or publishes; nothing here should be taken for granted about that closing step in advance. Whether notarisation is expected ahead of the UK check depends on the issuing body and on what the embassy specifically asks for that record type.
None of this changes what happens on the UK side: Westminster Register Office issues a fresh certified copy of a civil record where wanted, and the FCDO Legalisation Office carries out its check on the paper. Guinea still asks for one more step beyond both of those, arranged separately once the UK paperwork is complete and ready to send onward. A sender juggling a tight commercial calendar does well to open that embassy stage early, rather than leaving it until the stamped paper has already landed back home.
