The translation of some legal documents is only valid if signed by a sworn translator. This is particularly true for extracts of civil-status records, official acts, marriage contracts and diplomas. Judgements, company statutes, notarial acts and other official documents are also concerned. The sworn translator certifies his translation to be true to the original document and appends his stamp and signature at the bottom. The official document or a certified copy is then attached to the translation and the translator’s acknowledgement. When required, these translations are presented to the Registry of the Court of First Instance and the President legalises the signature ; the translation is then said « certified».
