A title is closer to a name than to a word
Hungary reads Hungarian, so an English record needs a Hungarian text alongside before an office there will work from it. A certified translation into Hungarian in Nottingham handles ordinary sentences the way you would expect. Titles are the exception, because a title does two jobs at once: it names a role, and it places that role in a system which only exists here.
Think of a Superintendent Registrar, a Chartered Surveyor or a Reader at a university. Each means something precise here and nothing at all in Hungarian. Turn the words across and you get a phrase that sounds plausible and describes no real job, which is worse than leaving it in English, because it looks like an answer.
Carry the title, then explain it
An official Hungarian translation in Nottingham keeps the printed title as it stands and puts a short plain description next to it. The description says what the role does, not what it is called. A reader in Hungary then has both: the exact string they can match against the source, and enough plain wording to know who signed the sheet.
Where the record is a civil one made in this city, the cleanest source is a fresh sheet. Nottingham Register Office issues certified copies of births, marriages and deaths from The Council House, Old Market Square, Nottingham NG1 2DT. A new certified copy prints the current titles clearly and keeps the sheet you already own out of the whole business.
Where title work goes wrong
The common failure is quiet promotion. A deputy becomes a head, an assistant becomes a manager, and nobody notices until a Hungarian office compares your file against a letter that says something else. A certified translation for Hungary avoids that by refusing to rank anything. The Hungarian text describes a role; it does not decide where that role sits.
The second failure is silence. A title gets dropped because it seemed like decoration, and the signature underneath it loses its meaning. Every role printed on the sheet goes across, including the ones in small type at the bottom, because that is often where the power to sign the record actually lives.
