South Africa's Hague status and the year on it
South Africa joined the Hague Apostille Convention in 1995. From that point one certificate has been the accepted form for British public papers used there, which is why document legalisation for South Africa is a single-stage job today rather than a chain of desks. For this destination the apostille is the correct and sufficient certification.
The date is easy to over-read. It records when the two countries came under the same arrangement, and it says nothing about how old your own document is. Nothing in that year changes which sheet you send, what the office charges to mark it, or how long the post takes to bring it home again.
The route from Brighton, end to end
An apostille issued in Brighton for use in South Africa is added by one office, and that office is not in the city. The Legalisation Office (Foreign, Commonwealth & Development Office) handles every British case from PO Box 6255, Milton Keynes MK10 1XX, working through the mail in both directions and keeping no public counter at all.
The Brighton end of the job is the paper, not a queue. Brighton & Hove Register Office at Town Hall, Bartholomew Square, Brighton BN1 1JA issues certified copies of birth, marriage and death records, and a fresh copy can travel in place of the original that stays at home with you.
What the certifying stage charges
Two figures are published for an apostille from United Kingdom to South Africa: £45 per document by standard post, and £40 per document on the next-day service open to registered businesses. Both are charged per sheet, so the count you settle at the beginning decides the total, not the length of the route.
No turnaround figure is published for this corridor, so no promised date belongs on this page. What is known is that the office works by mail in both directions. The days you can genuinely control are therefore the ones before the envelope leaves.
How many marked sheets the job needs
The certificate is fixed to one sheet, and whoever keeps that sheet abroad keeps the mark along with it. If two separate places each want the paper for their own file, that is two documents on this route and two charges, decided when you order copies rather than discovered later.
This is the one part of the job with real slack in it. A second certified copy ordered while the first is still at home costs a fee and no extra waiting. The same copy ordered after the file has already gone abroad costs the whole round trip a second time.
