The language Mauritania requires
A certified translation into Arabic is required for documents used in Mauritania, so an English record from Northern Ireland cannot go in on its own. A certified translation into Arabic in Belfast adds a second document to the file and leaves the first one exactly as it was. Nothing is written on the English sheet, and it is not stamped or endorsed in any way.
The four things to settle first
A job like this is easy to start badly. Four points are worth pinning down on day one: which sides of paper are really going in, which version of each record you hold, the date the file is due, and how many finished sets you want. Not one is a technical question, and all four are quicker to answer now than to unpick once a signed set exists.
Why the brief decides the calendar
Almost everything that can be planned here sits before the writing. The queue only starts when the page count is fixed and the scans are readable, and from there the run is steady. What varies wildly is the stretch beforehand, where a missing certificate or an unanswered question can hold a file for a fortnight while nothing is produced.
Where the Belfast source comes from
Northern Ireland runs its own civil registration, so a birth, marriage or death registered in Belfast is issued by the General Register Office for Northern Ireland (GRONI) at Colby House, Stranmillis Court, Belfast BT9 5RR, not by a registry in England or Wales. That office works by post, which gives it a waiting time of its own. Ordering the copy is therefore the first thing to set moving, before anything else in the brief is fixed.
Cost, pace and what a clear brief buys
The rate is about £25 for each page as issued, and standard production runs 3–5 business days once readable scans exist. A 48-hour route is there for a tight date. A certified translation for Mauritania is quoted from the page count, so the brief and the bill are the same conversation: settle what goes in, and the figure follows. An official Arabic translation in Belfast begun on a clear brief rarely needs a second run.
