What Is a Certified Translation?
A certified translation is a translation provided by a qualified professional translator, who signs a statement attesting that the translation is a true, complete and accurate version of the original document. It typically includes the translator’s signature, professional qualifications, and often a stamp or seal. Certified translations are accepted by courts, universities, immigration authorities, embassies, and other official entities.
In many cases, certified translations are the first step toward obtaining a notarised translation, which a notary public then attests to. For documents destined for use abroad, you may also need an apostille or legalisation stamp, depending on the destination country.
Why Certified Translation Matters
- Legal acceptance: Many jurisdictions (e.g. USCIS in the USA, UK Home Office, European courts) require certified translation to process your documents.
- Accuracy and completeness: Certified translations carry the translator’s or the translation agency’s legal responsibility, ensuring no omissions or alterations.
- Trust & authority: The signed certification and official formatting aligned for the governing authority’s rules, signals professional credibility to government bodies and institutions.
Types of Certified Translations
1. Certified Translation
Performed by a qualified translator within a given jurisdiction, with a signed declaration confirming accuracy and completeness. Often includes a seal or stamp and follows local formatting rules.
2. Notarised Translation
A certified translation bearing the endorsement of a notary public, attesting to the authenticity of the translator’s signature – commonly required for immigration or legal filings.
3. Apostille Translation
Used under the Hague Apostille Convention. The translation is affixed with an apostille stamp from the issuing authority, allowing direct international acceptance between subscribing countries.
4. Legalised Translation
For countries not part of the Hague Convention. A translation must be certified, notarised, and legalised by an embassy or consulate of the destination country.
Who Can Provide Certified Translations?
Requirements vary by country:
- U.S., U.K., Australia, New Zealand: Any competent translator can provide a certified translation—with a signed statement, including their professional qualifications, and date.
- EU and Latin American countries: Often require sworn or state‑appointed translators, authorised via legal exams.
