French on every form
Niger runs its public paperwork in French, so a record issued in English is only half of what a receiving desk needs. The French text is built sheet for sheet, so the shape of the source is kept. Nothing is boiled down and nothing is dropped, including the small print that sits under a stamp.
The sworn translator requirement
For French official use a sworn translator is required, and the credential is a traducteur assermenté. That translator has taken an oath before a court, which is what lets the certificate carry legal weight. It is a standing rather than a level of skill, and it cannot be added to finished work later on.
Reading the cost
The rate is about £25 for each page of the source. Because the count follows sheets, a file of ten dense pages and a file of ten sparse pages cost the same. Standard delivery runs 2-4 business days; express delivery lands within 24-48 hours, which suits a fixed date that will not move.
What arrives and how to file it
Three things come back: the French text, the scan you sent, and the signed certificate. Keep them together and in order. A certified translation for Niger handed over as loose sheets invites questions that a stapled, dated set never raises, and holding the bundle intact costs nothing at all.
Ordering a fresh civil copy
If a paper record is wanted in Niger as well as a translation, order a fresh certified copy rather than parting with the sheet you hold. Reading Register Office at Civic Offices, Bridge Street, Reading RG1 2LU issues certified copies of birth, marriage and death records for exactly this purpose, and the job is done by post.
