Certified vs Notarized vs Sworn Translation: What’s the Difference?
If you need to submit documents internationally, you’ve probably come across terms like certified translation, notarized translation, and sworn translation. They may sound similar, but they serve very different purposes.
In this guide, we’ll clearly explain the differences, when each one is required, and how to choose the right option for your situation.
What Is a Certified Translation?
A certified translation is a complete and accurate translation accompanied by a signed statement from the translator or translation company. This statement confirms that the translator is competent in both languages and that the translation is complete and accurate.
This is the standard for translations going to USCIS, therefore the most commonly required type of translation.
What Is a Notarized Translation?
A notarized translation involves a notary public, but the notary does not verify the translation itself, instead, they verify the identity of the translator and witness the signing of the certification. It is important to understand this: Notarization validates the signature, not the translation quality.
What Is a Sworn Translation?
A sworn translation is a translation done by an official-certified (sworn) translator in the country where the document will be submitted or used. These translators are approved by the government or official institutions and they place their signature, seal and license number to certify the translation.
When Do You Need Each Type?
Certified Translation (Most Common)
Use it when:
- Applying to USCIS
- General official use
This is the default requirement in most cases.
Notarized Translation
Use it when:
- Specifically requested by an institution
- Required for legal or court-related matters
Not always required, only when explicitly requested.
Sworn Translation
This one is very simple, use it when:
- Document will be used in a country that has sworn translators
If unsure, confirm with the receiving authority or with a qualified and experienced service provider.

Always confirm with the receiving authority.

- Notarization → usually NOT required (depending on the country)
- Sworn translation → required in most cases (depending on the country)

How to Choose the Right Option?
Before hiring a translation service, ask yourself:
1. Where will the document be used?
2. What will the document be used for?
3. What does the institution require?
If you don’t have all the answers, a professional translation service can guide you.
