Shorthand does not travel
Armenian is the language required for documents used in Armenia, and most of the page converts without difficulty. The exceptions are the compressed bits: letters after a surname, a body reduced to three capitals, a status written as a single character in a box. Each was invented to save space among readers who already knew what it meant, and a reader in Armenia is not one of them.
Meaning, not lookalike letters
The wrong move is to swap British initials for a similar-looking Armenian set, because that produces something that reads as an official abbreviation while standing for nothing at all. Writing out what the shortened form means keeps the page honest. It also makes the translated sheet longer than the source in places, which is normal and is not a sign that anything has been added.
The part only the issuer can answer
Some codes exist inside one organisation and nowhere else, and no amount of expertise will decode them from outside. Those are worth resolving at the source before translation rather than after. Where the paper is a civil record, Manchester Register Office at Heron House, 47 Lloyd Street, Manchester M2 5LE issues fresh certified copies, printed clearly enough that every abbreviation on the entry can be read with confidence.
Rate and timing
Pricing follows pages rather than difficulty, at £25 per page, so a certificate dense with codes is charged like any other sheet. Standard turnaround runs 2–3 business days once a clean scan arrives, and the express route delivers in 24 hours. Fixing the count first means the quote does not move once the translator meets the awkward parts of the page.
