What the Legalisation Office can put its mark on
An apostille is a slip that vouches for a signature or seal already on a paper. It adds nothing of its own to the story the paper tells. That single point explains most of the trouble people run into: the office cannot vouch for ink that is not there, so a bare copy or a screen print has no anchor for it to work from.
Where Armenia stands
Armenia has been inside the Hague Apostille Convention since 1994, and that is why the route stays short. Document legalisation for Armenia means one slip and one office, with no second desk waiting afterwards. The whole of the difficulty therefore moves back a stage, onto the paper you start with rather than the road it travels.
The Wolverhampton to Armenia route in practice
An apostille issued in Wolverhampton for use in Armenia is really issued in Milton Keynes, because a single national office does this work by post. There is no counter in the West Midlands doing it. What is local is the source of the paper: the register office at the Civic Centre holds the civil records for this city and prints signed copies of them.
That is also the safe way to keep your own certificate at home. A fresh certified copy comes from the same register and carries the same weight, so let the copy make the trip. If an envelope goes astray on a long postal route, you lose a reprint fee rather than the only birth record your family owns.
Cost and the clock
The official price is set per document, not per envelope: £45 by post as standard, or £40 for a registered business using the next-day service. Both routes end in the same slip. Timing is harder to pin down because the post sits on either side of the desk work, so a file tied to a start date should leave with room to spare.
