Embassy legalisation for use in Armenia
Start with the short answer. Armenia accepts a simpler single-step certification, so the consular chain plays no part in a file headed there. Nobody has to book a slot with a mission or set money aside for one. A sheet leaving Birmingham with a single British certificate on it is already in the shape an Armenian office expects to receive.
That leaves a different question, and it is the one people skip. A finished sheet is one object. The office it reaches keeps it, files it and does not post it back, so the number of papers you order at the start quietly decides how many places this run can reach before you have to begin again.
What an Armenian office actually reads
No consular desk stands anywhere in this route, so there is nothing to price, book or queue for on that side. What is read at the far end is the sheet itself: the body that issued it, the seal, the names and the dates. The single British mark tells that reader the signature above it is genuine, and that is the whole of its job.
The Birmingham → Armenia route step by step
Civil records start at Birmingham Register Office, Holliday Street, Birmingham B1 1TJ, which issues fresh certified copies of birth, marriage and death entries. Order every copy you expect to need while you are there. Two copies cost two fees, but a second order placed weeks later also costs a second wait, and that is the part people feel.
The set then travels together to the FCDO Legalisation Office, PO Box 6255, Milton Keynes MK10 1XX. That office works by post and has no public counter. It handles each sheet on its own merits, so a bundle sent in one envelope comes home as a bundle of separately certified papers rather than one paper with a note about the rest.
Cost & timing for this route
One office means one wait. Standard handling runs 7–10 business days, the express route runs 2–3 business days, and post at either end sits on top of both figures. An official fee applies to each sheet, so the bill grows with the count of papers rather than with the number of rounds you run. No second bill arrives, because no second office is involved.
Deciding the count before anything moves
So settle the number first. Write down who in Armenia will end up holding a file — an employer, a bank, a court, a school are the usual ones, and those are illustrations rather than a list you must match — then order a sheet for each of them. Legalize documents for Armenia once, in the right quantity, and the route is finished in a single pass.
