NAATI Translation vs Non-Certified Translation: Which Do You Need?

The short answer: if the translation is going to an Australian government body — the Department of Home Affairs above all — use a NAATI-certified translator. If it is only for your own understanding, a non-certified translation is fine and costs far less. If it is going overseas, NAATI may be the wrong question entirely: the receiving country decides whose translation it accepts, and it may not recognise an Australian credential.

What the terms mean

A non-certified translation is any translation that no accountable translator has certified: a bilingual friend's version, a machine translation, or a professional's informal draft. It may be perfectly accurate. What it lacks is anyone the receiver can hold responsible for its accuracy.

A NAATI-certified translation is produced by a translator holding a credential from NAATI, Australia's national certification body for translators and interpreters. The translation normally carries the translator's statement, stamp and practitioner number, which the receiver can check against NAATI's online directory. Credentials are issued for a particular language and direction, so a translator certified to translate into English is not necessarily certified to translate out of it.

Two other things often get confused with these:

A translation by an overseas professional, with the translator's full name, address and credentials stated on it. For documents going to Home Affairs, translations done outside Australia are generally accepted in this form.

A notarised translation. Here a notary attests the translator's signed declaration and binds the translation to the original or to a certified copy. The notary does not check the translation's accuracy; the act certifies the translator's signature. Some foreign authorities require this step.

The practical differences

	Non-certified	NAATI-certified	Overseas translator with details	Notarised translator's declaration
Who is accountable	No one	The NAATI-credentialled translator	The named translator	The translator; the notary certifies the signature only
Home Affairs, translated in Australia	No	Yes	Not applicable	Only if it is also by a NAATI translator
Home Affairs, translated overseas	No	Yes	Generally yes	Depends on the translator
Other Australian agencies	Rarely	Commonly expected	Check	Check
Foreign authorities	No	Sometimes, often with notarisation and apostille	Sometimes	Often part of what is asked for
Right for	Your own understanding	Most official Australian use	Documents translated where they were issued	Destinations that require it

When a non-certified translation is the right choice

More often than people expect. Paying for certification is wasted when:

• You received a document in another language and simply need to know what it says.
• You are checking whether a document is the right one before ordering a certified translation of it.
• The translation is for internal business use or your own records.
• You are gathering documents early and do not yet know who will receive them or what they will require.

A non-certified translation is never acceptable for an official submission. If a body asked for "a translation" without saying more, ask what kind before assuming it will take an informal one.

When NAATI certification is the right choice

• Visa, citizenship and other applications to the Department of Home Affairs where the translation is done in Australia.
• Most other Australian government agencies, registration bodies and licensing authorities, which commonly expect NAATI-certified translations. Check the agency's own published requirement.
• Australian courts, universities and professional assessment bodies, subject to their own rules.

For languages where NAATI does not offer certification testing, it has issued a different form of credential. If your language is less common, ask the agency whether that credential satisfies them.

When NAATI may not be what you need

The document is going overseas. NAATI is an Australian credential. Many countries require a translation made by a sworn or court-appointed translator on their own register, often in that country, sometimes after the apostille has been issued. Others will accept a NAATI translation only once the translator's declaration has been notarised and apostilled. Ask the receiving authority who may translate, and at which point in the sequence.

The document is coming from overseas for use in Australia. You may not need an Australian translator at all. A translation done where the document was issued, carrying the translator's full name, address and credentials, is often acceptable. Check the Australian receiver's instructions first.

Checking a certified translation before you submit it

• The translator's name, stamp and practitioner number appear on it.
• The practitioner is listed in NAATI's directory for that language and direction.
• Every page is translated, including stamps, seals, handwritten notes and the reverse of each page.
• Names are spelled as they appear on your passport, with the original spelling noted where it differs.

Frequently asked questions

Is a NAATI translation accepted overseas? Not automatically. Some countries accept it once notarised and apostilled; others require their own sworn translators. Hague Convention membership affects the authentication step and changes, so check it on the HCCH status table at the time you are acting.

Can I translate my own documents if I am fluent? Not for official purposes. Receivers expect an independent translator, and your personal interest in the outcome disqualifies you regardless of fluency.

Will a machine translation do? Only for your own understanding. No official body will accept one.

Does a notary check the accuracy of the translation? No. A notary witnesses the translator's declaration or certifies copies. The accuracy is the translator's responsibility.
