Certified vs. notarized translation: what's the difference?

Certification addresses the translation. Notarization is a separate signature or document process.

A certified translation and a notarized translation are not interchangeable terms. Lincua can provide a signed certification of translation accuracy and may arrange notarization when requested and available. The organization receiving the document determines what it needs.

At a glance

What each term describes

Certified translation

A written translation accompanied by a signed statement addressing completeness, accuracy, and the translator's competence for the work.

Check: Confirm the recipient's required wording, language pair, document scope, and delivery format.

Notarization

A separate notarial act connected with a signature or document process; it does not itself assess the linguistic accuracy of the translation.

Check: Ask the recipient whether a notarized signature is required in addition to a translation certification.

Why the distinction matters

A certification statement concerns the translation deliverable. Notarization concerns a different step involving a signature or document process. Adding one does not automatically satisfy a request for the other, and neither guarantees that a receiving organization will accept a document.

Start with the receiving organization's instructions

Requirements can differ by agency, court, school, employer, or other recipient. Ask what document, language, certification wording, notarization, and delivery format they require. Share those instructions with Lincua before the scope is confirmed.

For immigration-related documents

Lincua offers certified document translation for USCIS-related submissions, but it does not provide immigration legal advice or determine whether an agency will accept a particular document. The USCIS document translation page explains Lincua's service; follow the receiving agency's current instructions for your filing.

Documents and preparation

Requests may concern a birth certificate, marriage certificate, diploma, transcript, or another written record. Tell the team the source and target languages, document type, approximate length, intended recipient, deadline, and any written instructions. Contact the team before sending sensitive records so the delivery method can be confirmed.

Before you request

What to confirm before ordering

  • Does the recipient ask for a signed translation certification, notarization, or both?
  • Is there required wording, format, or delivery method?
  • Are the source documents legible, and what is the deadline?
  • Has the recipient given current instructions you can share with Lincua?

Helpful answers

Questions about certification and notarization

Does every certified translation need notarization?

No universal rule applies. Confirm the current requirements with the organization receiving your document.

Does notarization certify that the translation is accurate?

No. A notarial act is distinct from the translator's statement about the translation's completeness and accuracy.

Can Lincua arrange notarization?

Notarization may be available when requested. Tell the team what your recipient requires so availability and scope can be reviewed.

Will certification or notarization guarantee acceptance?

No. The receiving organization decides whether a submitted document meets its requirements.
