Sworn vs. Notarized Translation in Turkey

One office tells you that you need a "sworn" translation. Another asks for a "notarized" one. A third adds "and apostille." They sound like three names for the same thing, but they are three different steps — and getting the order or the type wrong is the most common reason documents get rejected.

The short answer

Think of it as layers that build on each other:

• Sworn translation — the translation is done by a sworn translator (yeminli tercüman), someone officially recognized in Turkey and registered with a notary office. This is the base layer, and it is broadly the same idea as a "certified translation" in the UK or US.
• Notarized translation — the sworn translation is then taken to a notary, who attests that it was signed by a registered sworn translator. It adds a layer of formal verification on top.
• Apostille — a separate, final step that confirms the authenticity of the notary's signature and seal so the document is accepted in another Hague Convention country.

At a glance

So which one do you actually need?

There is no single answer, because the authority that will receive your document decides — not the translator, and not us. A few useful rules of thumb:

• Submitting inside Turkey (a court, a ministry, an immigration or residence-permit office): a sworn translation is the standard expectation, and many offices also want it notarized.
• Banks and private companies are often more flexible, but they set their own rules — it is worth asking before you pay for extra layers you may not need.
• Using a Turkish document abroad (a university, an embassy, a foreign court): you will usually need the translation notarized, and very often an apostille on top. The foreign authority's instructions come first.

When in doubt, ask the receiving office a single question: "Do you require a sworn translation, a notarized translation, and/or an apostille?" Their answer saves you both time and money.

The mistakes we see most often

• Assuming a translation agency's own stamp is "sworn." A company stamp or a signed statement of accuracy is not the same as a translation by a registered sworn translator.
• Doing the steps in the wrong order. An apostille authenticates a signature that already exists, so it has to come after the notarization — not before.
• Paying for layers nobody asked for. Not every office needs every step. Confirm the requirement first.
• Translating a poor copy. Blurry scans and cropped pages cause delays and, sometimes, errors in names and numbers. A clear, complete scan matters.

How we handle it

Because we coordinate with more than five notary offices around Istanbul, we can take care of the whole chain for you in the right order: sworn translation, notarization, and — where your destination requires it — the apostille, including through our remote E-Apostille service. You send us a clear scan, tell us where the document will be used, and we tell you exactly which steps it needs before you spend anything on extras.
