Apostille, notarization and certified translation: what each step does

These terms describe different functions, and the correct sequence depends on the document, destination and receiving authority. NARIA helps clients define the translation scope without navigating the process alone.

Certified translation

A certified translation typically includes a statement by the translator addressing accuracy, completeness and competence. The exact meaning varies by receiving country and institution. For USCIS, the governing rule focuses on a full English translation and the translator’s signed certification.

A certified translation is not automatically notarized or apostilled. Those are separate steps and should be added only when the receiving authority requires them.

Notarization and sworn translation

Notarization generally adds an official act related to an identity, signature or document procedure. In Türkiye, notarial translation procedures involve an individual translator whose language competence and oath documentation are maintained by the notary handling the work.

The label “sworn translator” is jurisdiction-specific. It should not be assumed to satisfy a foreign agency’s separate wording for a translator certification, nor should a U.S.-style certification automatically be described as a Turkish notarial translation.

What an apostille does — and does not do

The HCCH Apostille Convention replaces traditional legalization with a single certificate for qualifying public documents used between contracting parties. The apostille verifies the authenticity of the signature, the capacity of the signer and, where appropriate, the seal or stamp.

The HCCH is explicit that an apostille does not certify the content of the underlying document. It also does not decide whether the destination authority will accept the document for a particular purpose.

Why document-specific planning matters

A generic online sequence cannot account for every country, authority and document type. Starting with the wrong step may create unnecessary cost or require the work to be repeated.

NARIA reviews the intended destination and available document before confirming the translation scope. When notarization, apostille or an additional certification affects that scope, the relationship is explained clearly so the client can proceed with confidence.

FREQUENTLY ASKED

Short answers

Does an apostille certify that the document is true?

No. It authenticates the origin of the public document — the signature, the signer’s capacity and the seal or stamp — not the truth of the document’s content.

Is every certified translation notarized?

No. Translator certification and notarization are separate. Some receiving authorities request both; others require only the translator’s certification.

Should the apostille be translated too?

The apostille and any attached notarial certificate are reviewed together with the underlying document so NARIA can define a complete and consistent translation scope.
