Certified translation in Coventry for use in Nigeria
People often ask for a translator to come along to a meeting. That is an interpreter, and it is a different trade with different training. What Nigeria works from is a file, so what you need is written down: English wording with the translator's signed certificate of accuracy clipped to it.
The source record stays exactly as it is. A translation does not alter the paper it describes and does not stand in its place. You send both, so the reader can hold the English next to the record it came from and see for themselves that the two agree.
The language Nigeria requires
Nigeria reads official papers in English, so any record in another language needs the English version before it is of use. If your certificate was issued in English to begin with, there is nothing to translate, and paying for a translation would buy you nothing at all.
That test follows the sheet in front of you rather than your own first language. A record written in Portuguese still needs an English version even if you speak English perfectly well, because the reader is checking the paper and not the person who carries it.
Certification Nigeria accepts
The accepted form is a certified translation with certificate of accuracy. The translator writes out the English, then signs a short statement that the English says what the source says. A professional certified translator can do that. No court has to appoint anybody first.
It is worth knowing because the two routes get mixed up. Where a country keeps a register of court-sworn translators, nothing else will do there. For a certified translation for Nigeria the signature and the written statement carry the weight, so the pool of people who may do the work is far wider.
Per-page cost & turnaround
Work is priced by the page, at about £25 per page, so a long record costs more than a short one. Standard work takes 2–3 business days once clear scans of every sheet are in hand. Where a date is closing in, express work comes back in 24 hours.
That clock starts on the translation side, not at the register office. If you still need a fresh certified copy of a birth or marriage record, add its wait on top. Coventry Register Office at Cheylesmore Manor House, Manor House Drive, Coventry CV1 2ND issues those copies; it does not translate them.
Acceptance in Nigeria
What reaches the reader is an official English translation in Coventry, signed and dated by the translator who wrote it, travelling with the record it describes. Nothing in that file needs a person standing by to explain it. That is the point of the written form: it works when you are somewhere else.
If you are also attending an interview or a hearing, that is a separate arrangement with a separate person, and it does not stand in for the paper. The written text stays on the reader's file long after any meeting ends, which is the reason they ask for it in the first place.
