What Is Certified Sworn Translation?
Certified Sworn Translation (also known as sworn translation) is a form of translation in which the translated document is produced by a “sworn translator” — a professional who has taken an official oath before a legal authority attesting to the accuracy, completeness, and faithfulness of the translation.
A valid Sworn Translation always includes:
- An oath statement confirming absolute accuracy.
- The official signature and seal of the sworn translator.
- The date and identifying information of the translator.
Thanks to the oath and legal certification, a Sworn Translation has legal validity equivalent to the original document in the country where it is applied. It is commonly required for documents submitted to courts, embassies, government authorities, or important international procedures.
Distinguishing between Sworn Translation and Certified Translation::
- Sworn Translation: Must be performed by a sworn translator licensed by the Ministry of Justice or an equivalent authority. This form is commonly used in countries such as France, Spain, Italy, Brazil, and others.
- Certified Translation: Requires only a certification signature from the translator or translation company, without a legal oath. It is widely used in the UK, the United States, Canada, and similar jurisdictions.
