Which Documents Require a Sworn Translation?

What Makes a Translator "Sworn"?
A sworn translator has taken an oath before a Turkish notary for a specific language, with their identity and authority placed on record. Their stamp and signature carry legal responsibility for the accuracy of the translation. That is the difference from an ordinary translation: even if the text is perfect, an unstamped translation is not accepted in official proceedings.
Documents That Require a Sworn Translation
| Document | Why |
|---|---|
| Civil registry extract, birth and marriage certificates | Identity and civil status procedures |
| Diploma, transcript, student certificate | Recognition and enrolment applications |
| Contracts, powers of attorney, court decisions | Legal validity |
| Bank statements, tax certificates, balance sheets | Financial declarations |
| Medical reports, discharge summaries, prescriptions | Institutional and insurance procedures |
| Trade registry gazette, signature circulars | Corporate procedures |
When the Stamp Is Not Enough
For some procedures the translator's stamp alone will not do; notarisation is added on top, and if the document will be used abroad, an apostille as well. The chain runs:
Sworn translation → Notarisation → Apostille
Always confirm in writing which layer the receiving institution requires — each layer adds cost and time.
Where It Is Not Needed
Internal correspondence, marketing copy, website content, presentations and product catalogues are not submitted to an official body, so no sworn stamp is required. What matters there is terminology consistency and readability, not certification.
The Most Common Reason for Rejection
Not a content error — an inconsistency in names or dates. Name spellings, date formats and institution names must be carried over exactly as they appear. A translator who "corrects" them can invalidate the document.
