English at both ends
Trinidad and Tobago runs its administration in English, and so does the United Kingdom, which means most of a file crossing this route needs nothing done to it. The exception is the page issued somewhere else. Caribbean family files often carry one, picked up in a neighbouring country with a different official language.
What certification means here
A certified translation into English in Reading is judged on the certificate of accuracy that comes with it. The translator states the source language, the target language and the date, then signs. That statement is a claim a named person stands behind, which is why it is fixed to the set rather than emailed on its own.
Cost, timing and the usual files
The rate is about £25 for each page of the source, with standard delivery in 2-3 business days and express delivery within 24 hours. Immigration and citizenship files, marriage records and property papers make up most of the traffic. Each of them is prepared in the same way, sheet by sheet, under a single signed certificate.
