Certified Translation vs. Notarized Translation: What’s the Difference?
Updated: Sep 9

If you have been asked to translate an official document, you may have encountered two terms that sound similar but mean very different things: certified translation and notarized translation.
The distinction matters.
A certified translation focuses on the accuracy and completeness of the translation. Notarization, on the other hand, generally verifies the identity and signature of the person signing a statement.
In other words, a notary does not normally determine whether a translation is linguistically correct.
Understanding this difference is particularly important when submitting birth certificates, marriage certificates, academic records, court documents, immigration documents, financial records, or other official paperwork to government agencies and institutions.
The receiving organization ultimately determines what it requires, so knowing whether you need certification, notarization, or both can save time and prevent unnecessary expenses.
What Is a Certified Translation?
A certified translation is a translation accompanied by a signed statement confirming that the translation is complete and accurate.
In the United States, the certification statement typically identifies the translator or translation provider and confirms the translator's qualifications or competency to translate between the relevant languages.
A certification may include:
The translator's name
The source and target languages
A statement confirming that the translation is complete and accurate
A statement regarding the translator's competency or qualifications
Identification of the translated document
The translator's signature
The date
Contact information when required
The exact wording and information required can depend on the organization receiving the translation.
Certified translations are frequently used for official documents because they provide a formal statement connecting a translator or translation provider to the accuracy of the translated material.
If you need an official document translated, eGO Translate provides professional translation services for personal, legal, immigration, academic, financial, and other documentation.
What Is a Notarized Translation?
The term "notarized translation" can be misleading.
In most situations, the notary is not notarizing the translation itself and is not evaluating whether the translation is accurate.
Instead, the notary generally witnesses or authenticates the signature of the person signing a certification or sworn statement associated with the translation.
The process may look like this:
A document is translated.
The translator prepares a certification or declaration.
The translator signs the statement according to the applicable notarization procedure.
A notary verifies the signer's identity and completes the notarial act.
The notary's role concerns the signature and identity of the signer, not the translator's linguistic decisions.
This distinction is especially important when dealing with legal translation services, where the terms "certified," "notarized," "sworn," and "official" may have different meanings depending on the jurisdiction and receiving authority.
Certified Translation vs. Notarized Translation: The Main Difference
The easiest way to understand the difference is to look at what each process is intended to establish.
A certified translation addresses the translation itself.
The translator or translation provider states that the translation is complete and accurate and provides the appropriate certification.
A notarized translation generally adds another procedural step in which a notary verifies the identity or signature of the person making the certification or declaration.
The notary does not normally compare the source document against the translated version or determine whether the translator chose the correct terminology.
Therefore:
Certification relates to translation accuracy and responsibility.
Notarization relates primarily to authentication of a signature or signer.
They serve different purposes.
Does a Certified Translation Have to Be Notarized?
No. A certified translation does not automatically need to be notarized.
Many organizations accept a properly certified translation without notarization.
Whether notarization is required depends on the receiving institution and the purpose for which the document is being submitted.
For example, one organization may request:
A certified English translation
while another may specifically request:
A certified and notarized translation
Those instructions should not be treated as interchangeable.
If notarization is not required, adding it does not necessarily make the translation more accurate or more acceptable.
Before ordering a translation, check the requirements of the government agency, university, court, employer, licensing board, financial institution, or other organization receiving the document.
Does USCIS Require Notarized Translations?
For documents submitted to U.S. Citizenship and Immigration Services, USCIS regulations require foreign-language documents to be accompanied by a full English translation that the translator has certified as complete and accurate, together with certification that the translator is competent to translate from the foreign language into English.
The federal translation requirement itself does not generally require the translator's certification to be notarized.
This distinction is important because applicants sometimes pay for notarization simply because they assume that every immigration translation needs it.
What USCIS is specifically concerned with under its translation regulation is a complete English translation and the translator's certification.
Applicants should still review the current instructions for the particular form they are filing because additional documentation requirements can vary.
For documents being prepared for an immigration matter, see eGO Translate's immigration translation services.
What Does USCIS Mean by a Certified Translation?
USCIS does not use "certified translation" to mean that every translator must hold a particular federal translator license.
The relevant requirement centers on the translator certifying that:
The English translation is complete and accurate.
The translator is competent to translate from the source language into English.
This creates another distinction that is important to understand:
A certified translation and a certified translator are not the same thing.
Certified Translation vs. Certified Translator
These terms are frequently confused.
A certified translation is a translated document accompanied by an appropriate certification statement.
A certified translator is an individual who has obtained a particular professional credential or certification.
For example, the American Translators Association offers certification for translators in certain language combinations.
However, according to the American Translators Association, a translator does not necessarily need to hold ATA certification in order to provide a certified translation in the United States.
That does not mean qualifications are unimportant.
Professional experience, subject-matter knowledge, linguistic ability, attention to detail, and familiarity with official documents can all influence translation quality.
It simply means that the words "certified translation" describe the document and accompanying certification, while "certified translator" describes a credential held by the translator.
What Does a Notary Actually Verify?
A notary's exact powers and procedures vary by jurisdiction, but notarization generally involves verifying the identity of a signer and completing a legally recognized notarial act.
A notary typically does not:
Translate the document
Proofread the translation
Compare every sentence against the source
Verify terminology
Confirm that names have been translated or reproduced correctly
Determine whether the translator is linguistically competent
Guarantee that an agency will accept the translation
This is why a notary seal should not be interpreted as proof that a translation is accurate.
A poorly translated document does not become a good translation simply because a signature associated with it has been notarized.
When Is a Certified Translation Commonly Required?
Certified translations are frequently requested when documents are being submitted for official or administrative purposes.
Examples may include:
Immigration applications
Visa applications
Birth certificates
Marriage certificates
Divorce decrees
Adoption records
Court documents
Police records
Criminal records
Diplomas
Academic transcripts
Professional licenses
Employment records
Financial documents
Government records
Civil registry documents
Name-change records
The receiving authority determines whether certification is required.
For educational records such as diplomas, certificates, and transcripts, eGO Translate also offers academic translation services.
When Might a Notarized Translation Be Required?
Some organizations, legal procedures, foreign authorities, credentialing bodies, universities, or administrative offices may specifically request a notarized translator statement.
The requirement may depend on:
The country where the document will be used
The type of proceeding
Local laws
Court rules
Institutional policy
The type of document
The organization receiving the translation
If the instructions explicitly say that the translator's certification must be notarized, a standard certified translation may not be sufficient.
The reverse is also true.
If an organization requests only a certified translation, notarization may be unnecessary.
The safest approach is to obtain the receiving organization's requirements before ordering the service.
Are Certified and Notarized Translations the Same as Sworn Translations?
No.
"Sworn translation" is another term that can cause confusion because translation systems vary significantly between countries.
Some countries regulate translators through government ministries, courts, professional registers, or other official systems. A translator may need to receive formal authorization before producing translations recognized for certain official purposes.
Depending on the country, such professionals may be called:
Sworn translators
Official translators
Authorized translators
Public translators
Court-appointed translators
The United States does not use one universal nationwide "sworn translator" system equivalent to those found in some other countries.
Therefore, a document described as a "sworn translation" in one country should not automatically be assumed to be equivalent to a U.S. certified translation.
Always evaluate the requirements of the authority that will actually receive the document.
Is a Certified Translation the Same as an Apostille?
No.
An apostille is also entirely different from translation certification and notarization.
An apostille is a form of authentication used for certain public documents being presented internationally between countries participating in the Hague Apostille Convention.
A translation certification addresses the translation.
Notarization generally addresses a signature or signer.
An apostille authenticates the origin of certain public documents or notarial acts for international use.
Depending on the situation, a person could potentially need more than one of these processes.
For example, an international document procedure might involve:
Obtaining an official document.
Obtaining an apostille when required.
Having the document translated.
Obtaining certification of the translation.
Obtaining notarization if specifically requested.
However, this sequence is not universal. The requirements depend entirely on the country, authority, and purpose involved.
Does Notarization Make a Translation More Official?
Not necessarily.
This is a common misconception.
A notary seal may make a particular signed statement formally notarized, but it does not automatically increase the linguistic quality of the translation.
The quality of a translation depends on factors such as:
The translator's language skills
Knowledge of the subject matter
Understanding of specialized terminology
Accuracy
Completeness
Careful handling of names and numbers
Proofreading
Consistency
Appropriate formatting
Notarization performs a separate legal or administrative function.
Therefore, when translation quality is important, the primary concern should still be whether the document was translated accurately and completely.
What Should a Certified Translation Include?
Although specific requirements vary, a professional certified translation will typically contain the translated document together with a certification statement.
The translation itself should accurately represent the readable content of the source.
For an official document, this may include:
Titles
Headings
Names
Dates
Numbers
Paragraphs
Tables
Stamps
Seals containing readable text
Handwritten annotations
Certification statements
Signatures or signature indicators
Footnotes
Registry information
A certified translation should not simply summarize the document.
If the receiving agency requires a complete translation, omitting sections because they appear unimportant can create problems.
Can I Certify My Own Translation?
The answer depends on the requirements of the organization receiving the document.
In the United States, there is no universal rule requiring every certified translation to be completed by an ATA-certified translator.
The American Translators Association notes that translations for yourself or family members may be viewed unfavorably by some end users even where there is no explicit rule prohibiting them.
For important official procedures, independence can therefore matter in practice.
A receiving authority may also have its own restrictions regarding who can prepare or certify a translation.
Before translating your own documents, verify the requirements of the institution receiving them.
Can a Translation Company Certify a Translation?
Yes, depending on the receiving organization's requirements.
The American Translators Association explains that a translation can be certified by an individual translator or by an appropriate representative of a translation company.
Professional translation providers frequently manage the translation, proofreading, formatting, and certification process as part of one service.
This can be particularly useful when a project involves multiple documents or specialized material.
For example, eGO Translate provides specialized legal translation services, medical translation services, academic translation services, and financial translation services.
Does a Certified Translation Need a Stamp?
Not necessarily.
There is no single universal stamp that turns a translation into a certified translation throughout the United States.
Some translators or translation companies may use professional stamps, seals, letterhead, or other identifying information as part of their certification process.
Some credentialed translators may also have access to professional certification seals.
However, the receiving organization's requirements are more important than the visual appearance of the certification.
A translation should not be considered acceptable simply because it contains an impressive-looking stamp.
The contents of the certification and the requirements of the receiving authority matter more.
What Documents May Require Both Certification and Notarization?
Requirements vary significantly, but certification and notarization may both be requested in certain legal, administrative, educational, international, or licensing contexts.
Possible examples include:
Court submissions
International legal procedures
Foreign university applications
Professional licensing applications
Corporate documents
Powers of attorney
Affidavits
Certain international transactions
Documents being submitted to foreign government authorities
This does not mean these documents always require notarization.
For example, one court may require a certified translation while another may require an affidavit or declaration executed under a particular procedure.
Always follow the specific instructions provided for your case.
How Do I Know Which Type of Translation I Need?
Before ordering a translation, ask the organization receiving your documents exactly what it requires.
Questions worth confirming include:
Do you require a certified translation?
Does the certification need to contain specific wording?
Does the translator need particular credentials?
Does the translator's signature need to be notarized?
Do you require an original signed certification or is a digital copy acceptable?
Does the document require an apostille?
Does the entire document need to be translated?
Are there country-specific requirements?
Are there formatting requirements?
Whenever possible, obtain the requirements in writing or find them on the official organization's website.
This is safer than relying on assumptions or on requirements that applied to another person's case.
Common Mistakes When Ordering Official Translations
Understanding the terminology can prevent several common problems.
Assuming Every Certified Translation Must Be Notarized
Certification and notarization are separate processes. Not every certified translation requires notarization.
Assuming a Notary Verifies Translation Accuracy
The notary generally verifies the signer or signature, not the linguistic accuracy of the translation.
Confusing a Certified Translation With a Certified Translator
A translation can be certified without necessarily being prepared by a translator holding a particular professional certification, unless the receiving authority specifically requires such a credential.
Assuming USCIS Requires Notarization
USCIS requires qualifying foreign-language documents to have full English translations with the appropriate translator certification. The general USCIS translation regulation does not itself require notarization.
Ordering an Apostille When Only a Translation Is Needed
Apostilles and translations serve different functions.
Translating Only Part of an Official Document
If a full translation is required, translating only the information that appears important may make the submission incomplete.
Not Checking the Receiving Institution's Requirements
Ultimately, the organization receiving the translation determines what documentation it will accept.
Certified Translation or Notarized Translation: Which One Do I Need?
The answer depends on where the document is going.
If an organization requests a certified translation, you generally need the translated document together with an appropriate statement certifying its completeness and accuracy.
If it requests that the translator's statement or certification be notarized, then an additional notarial step may be required.
If the organization requests both, both requirements should be satisfied.
The key is not to assume that "certified," "notarized," "apostilled," and "sworn" all mean the same thing. They do not.
Each serves a different purpose and can involve different people, procedures, and legal effects.
Professional Certified Document Translation
Official documents deserve careful handling.
Names, dates, signatures, stamps, seals, legal terminology, registration numbers, annotations, and other details can all affect the meaning of the document.
A professional translation should represent the source faithfully rather than summarize it, add information, or silently correct information that appears in the original.
