Sworn vs Certified vs Notarized Translation
By Burak Ünal, Founder & Sworn Translator (English, French) · Updated 2026-07-13
Sworn, certified and notarized translation are related but not identical. Knowing which one you need saves time and rejected documents.
Key takeaways
- Sworn: made by a translator sworn before a Turkish notary.
- Certified: accompanied by a statement of accuracy; for official use it is done via a sworn translator and notarized.
- Notarized: a sworn translation certified by a notary - what most Turkish authorities require.
These terms are often used interchangeably, but they mean different things in Turkey. Here is how they compare.
Sworn translation
A sworn translation is produced by a translator who has taken an oath before a Turkish notary. The translator's competence and signature are on record, which is the basis for official acceptance.
Certified translation
A certified translation is a translation accompanied by a statement of accuracy. In Turkey, certification for official use is normally provided through a sworn translator and then notarized.
Notarized translation
A notarized translation is a sworn translation that a Turkish notary has certified. Notarization is the step most Turkish authorities ask for.
Which one do I need?
- For most Turkish official procedures: a sworn translation that is then notarized.
- For use abroad: notarization plus an apostille.
- For business or website content: a professional translation, no certification needed.
