What is a Sworn Translator?

A Sworn Translator (also called a Certified Translator) is authorized by a public institution to carry out the translation of legal documents. Once translated, the documents are recognized as official by the local administration. Legal documents can only be translated by sworn translators with appropriate accreditation. The translation of a legal document provided by a non-certified translator has no value according to the law. Hiero conducts a background check on all translators using the software, to ensure their certification is valid and up to date.
