The difference between a sworn translation and a notarised translation

What is a sworn translation?

A sworn translation is prepared by a translator who has taken an oath before a notary and certified with the translator's own stamp and signature. Through this certification, the translator declares that the translation corresponds to the source document.

A sworn translator's authority is valid before the notary where the oath was taken. Translators therefore complete the required formalities separately with each notary they work with.

What is a notarised translation?

A notarised translation is a translation prepared by a sworn translator and certified by a notary. The notary verifies the translator's oath registration, attaches the translation to the source document, and applies a seal and certification statement.

This is the format required for most applications to institutions in Türkiye. If the document will be used abroad, notarisation alone is often insufficient; an apostille is also required.

Which type is required in each situation?

There is no universal rule; the requirement is determined by the institution requesting the document. Although the following practices are common, exceptions exist:

• Consular and visa applications: notarisation is usually required.
• YÖK diploma equivalency applications: a notarised translation is required.
• Court and enforcement files: notarisation is required.
• Applications to certain private institutions and companies: a sworn translation may be sufficient.

Checking the receiving institution's current list of required documents prevents unnecessary costs and delays.

The difference in costs

A sworn translation involves only the translation fee. A notarised translation also involves a notarial fee, which is determined and collected by the notary.

When requesting a quotation, it is therefore advisable to ask for the translation fee and notarial costs to be stated separately.
