Certified Legal Document Translations

Federal, state, and local courts in the United States require certified legal document translations in English of foreign-language documents that are relevant to the court case.

LinguaOne will deliver your translated legal document with a Certificate of Accuracy signed by a certified translator to confirm that it is a true and accurate translation.
