What ends up on the page
When the file comes back from Milton Keynes it carries one addition: the certificate the FCDO Legalisation Office puts on it. That is the mark Russia accepts, and there is no room on the sheet for another. Embassy attestation for Russia has not been withheld or delayed — it has no place in a route that closes at the British office.
The rest of the bundle is yours to assemble. A certified extract of the Scottish record, the British certificate sitting on it, and the Russian text bound alongside. A registry clerk in Moscow or an admissions desk in Kazan reads that set as one file, and there is nothing further to collect anywhere before it goes out.
When somebody expects a second stamp
Requests for a consular stamp usually come from a form rather than from a person who has looked at your paper. Old checklists survive in staff handbooks and university packs for years after the rule behind them moved on. Embassy legalization for Russia from Edinburgh sits on plenty of those lists, and it is the list that has gone stale rather than your file.
The practical answer is to send the finished bundle and let it speak for itself. Name the FCDO Legalisation Office in the covering note as the body that certified the paper, and give the date it did so. A clerk holding a complete, readable file rarely goes looking for a stage that the route no longer has in it.
Which papers usually go this way
The Edinburgh files that head for Russia are mostly personal ones. A marriage entry so a registry there can record a wedding held in Scotland, a birth entry for a child born in Britain to Russian parents, a death entry to settle an estate, a degree for a job or a further course. Each is a civil record or a school paper rather than a company one.
That shapes the practical advice. Civil records come from a register office and can be reordered if one goes astray; a degree comes from the awarding university and generally cannot, so a certified copy earns its keep there. Whichever it is, the route runs the same way once the record exists, and the only real variable is how fast the first sheet reaches your hand.
