A NAATI translation does not have a fixed expiry date. If the translator held the relevant certification when the translation was completed, the translation remains valid. What can expire is the source document, or a receiving authority may require documents to have been issued recently. Always follow the authority’s current requirements.
Do NAATI translations expire?
No. NAATI does not set an expiry date for a translation, so a compliant translation can remain valid indefinitely.
The key question is whether the translator held the relevant NAATI certification when the translation was completed. If so, and the translation includes the translator’s declaration, Certified Practitioner Number (CPN) and NAATI stamp, it is a formal certified translation. It does not become invalid merely because time has passed.
You can check the translation at any time. Search the CPN shown on the translation in the NAATI Online Directory, or scan the QR code on a NAATI digital stamp. Confirm that the translator and certified language direction match the translation.
Why might an authority say a translation is too old?
Time limits usually apply to the source document or its issue date, not to the translation itself. This distinction causes most misunderstandings.
When an organisation says a document is “too old”, it usually means one of two things:
- The source document has its own validity period. For example, the Department of Home Affairs states that police certificates used for character requirements are generally accepted for 12 months from the date of issue. See the Home Affairs character requirements. A new translation cannot make an expired source document current again.
- The receiving organisation requires recently issued material. Some banks, schools and service counters ask for a document or translation issued within the previous few months. A period of 3–12 months is common in practice, but it is the organisation’s own requirement rather than a NAATI rule.
Retranslation does not extend the validity of the source document. If a police certificate was issued in 2024 and translated again in 2026, Home Affairs still treats it as a document issued in 2024.
How different authorities treat NAATI translation validity
Australia does not have one universal validity period for translations. The table summarises common requirements encountered in our work, checked in August 2026.
| Authority or use | Translation itself | Common source-document requirement | Practical point |
|---|---|---|---|
| Department of Home Affairs: visas and character checks | No fixed expiry date | Police certificates: generally 12 months from issue | The source-document issue date controls the period; retranslating does not restart it |
| State driver licensing authorities | No fixed expiry date | No single national period | NSW accepts translations from specified sources; follow the current rules of the relevant state or territory |
| Banks and financial institutions | No fixed expiry date | Some request documents issued within the previous 3–6 months | Requirements vary by bank and branch, so confirm before attending |
| Schools and skills assessment bodies | No fixed expiry date | Follow the institution’s admissions or assessment rules | If a transcript or other record has been updated, translate the current version |
| Courts and legal proceedings | No fixed expiry date | Follow the court’s or lawyer’s instructions | Long-running matters may require newly issued supporting material or an updated translation |
The pattern is consistent: the translation usually has no set expiry date, while the source document and the receiving organisation’s rules determine whether it can be used. The safest step is to ask the receiving organisation whether it will accept both the translation and the source document before submission.
Does a translation remain valid after the translator’s NAATI certification expires?
Yes. Validity depends on the translator’s certification status when the translation was completed, not on whether the translator renews that certification later.
NAATI certification is not necessarily held for life and must be recertified periodically. A customer may discover that the translator’s certification has since expired and worry that an older translation is invalid. A translation completed while the certification was current does not expire simply because the translator’s status later changes.
The reverse is also true: a translation issued only after the translator’s certification had expired can be a problem. When checking an older translation, compare its completion date with the certification period as well as checking the CPN. For step-by-step instructions, see How to Verify a NAATI Translation →.
When do you need a new translation?
A new translation is generally worthwhile in four situations. Otherwise, the existing translation can usually continue to be used.
- The source document expired or was replaced. Examples include a police certificate older than the accepted period or a newly issued driver licence. Obtain the new source document before arranging another translation.
- The source information changed. If a transcript has new results or a household register has been updated, the old translation no longer matches the current document.
- The receiving organisation expressly requires a recently issued translation. Follow its written instructions or current counter policy.
- The old translation is defective. Do not use a translation that has no CPN, cannot be linked to the translator, shows the wrong language direction or contains incorrect information.
How can I check whether my translation is still usable?
Use this three-step check. It usually takes only a few minutes.
| Step | What to do | What to confirm |
|---|---|---|
| 1. Verify authenticity | Scan the QR code on the NAATI digital stamp or search the CPN in the NAATI directory | The translator is listed and the language direction matches |
| 2. Check the source document | Review its issue date and whether any information has changed | The document is within the authority’s required period and still current |
| 3. Ask the receiving organisation | Confirm acceptance of both the translation and source document before submission | The organisation’s current requirement is the final standard |
If a new translation is required, common standard documents such as identity cards, birth certificates, marriage certificates and driver licences cost A$30–65 per document. The price includes translation by a NAATI-certified translator, a translator declaration, NAATI digital stamp and PDF delivery, with completion within 24 business hours after payment. See the document translation price list.
NAATI translation validity FAQs
Does a NAATI translation remain valid after the translator’s certification expires?
Yes. If the translation was completed while the translator held the relevant NAATI certification, a later expiry, recertification or career change does not affect the earlier translation. The relevant point is the translator’s certification status when the translation was completed.
Can retranslating a document extend the original document’s validity?
No. The source document’s validity is calculated from its issue date, regardless of when it is translated. For example, a police certificate accepted by Home Affairs for 12 months does not receive a new validity period when translated again. A newly issued source document is required to restart the period.
How long can I use a driver licence translation in Australia?
The translation itself has no fixed expiry date. How long it can be used depends on the original licence and the relevant state or territory rules for overseas licences, including visa status and residence periods. See our driver licence translation guide.
How can I verify whether an old translation is a genuine NAATI translation?
Scan the QR code on the NAATI digital stamp, or enter the CPN shown on the translation in the NAATI Online Directory at directory.naati.com.au. The translator must be listed and the certified language direction must match the translation. Do not use a translation if the CPN cannot be verified.
