Does a certified translation expire, and can you use it again?
A translation has no expiry date of its own. NAATI says a translation by one of its credentialed translators “remains valid indefinitely”. What goes out of date is the document underneath it, or the details on that document. Here is how to tell whether the translation you already have still fits, in NAATI’s and Home Affairs’ own words.

The short answer: the translation does not expire, but it only ever describes one document
NAATI answers the question directly on its page about translator stamps: “The expiry date on the translation stamp relates to the translator’s credential, not the validity of the translation.” And on the same page: “A translation from a NAATI-credentialed translator should include the date at which the translation was completed and the translation remains valid indefinitely.”
So a translation made in 2024 is not stale in 2026 because of its age. The catch is that it is tied to the document it was made from. Home Affairs, for one, asks for the two together: “You must submit both the original document (non-English) and the translated document.” A translation stays useful for exactly as long as the original it goes with, unchanged, is still the one you are handing over.
If your document has not changed, you probably do not need a new translation, from us or anyone. Keep the PDF with the original and use it again. Before you lodge it somewhere new, ask that office what it needs.
The date on the stamp belongs to the translator
Most of the worry about expiry starts with a date printed on a stamp. NAATI explains what it is: “The ‘valid to’ date on these stamps refers to the recertification or potential expiry date of the practitioner’s credential (at the time the stamp was issued).” It is a date about the person, not the paper.
That date exists because credentials now run on a cycle. NAATI’s FAQ says: “All credentials issued under the current Certification System have a 3-year validity period and an expiry date. This means anyone wishing to maintain their credential after this time needs to recertify.” Elsewhere NAATI puts it plainly: “NAATI does not certify translations. We certify the translators who do translation work.”
On a digital stamp, which is what the translators we engage normally use under the NAATI certification option, you will not see a “valid to” date at all. NAATI says: “The digital stamp does not include the credential expiry date.” It carries the day it was made instead: “The ‘Stamp generated on XX/XX/XXXX’ details on the right-hand side replaces the ‘Translation date’ found on the physical stamp.” And that date is itself a check, because “the digital stamp cannot be generated unless the credential was active on that date.”
Older stamps have an answer too. NAATI says: “The NAATI Certification System commenced in January 2018 and succeeded the accreditation system that was in operation from 1977 – 2017.” Of the stamps issued under that older system, it says: “These stamps are no longer issued however the translations containing these stamps remain valid indefinitely.”
What if the translator’s credential has lapsed since?
It can happen. In NAATI’s words, “a credential will expire after three years if the translator or interpreter chooses not to recertify.” NAATI’s advice to translators in that position is about new work: “once your credential has passed its expiry date, it is considered expired until a recertification application is lodged. During this time, you should not accept new work until your credential has been renewed.”
For work already done, NAATI describes what its own check shows. Scanning the QR code on a digital stamp shows the translator’s credentials, and: “Where a practitioner has expired credentials but the stamp was generated when they were active, this will still state that the digital stamp is valid but you will see current credentials as expired.” So NAATI’s check looks at the credential as it stood on the day the stamp was made.
The result to take seriously is a different one: “In the case the QR code has been disabled for fraud or misuse, or it has been forged the returned information will say Digital Stamp: Invalid.” If you see that on a translation you hold, from any provider, take it up with whoever supplied it. How to run the scan, and the directory check for a physical stamp, is in how to check a translator’s NAATI credential.
When the document underneath goes out of date
Some documents carry their own clock. The clearest example is the police certificate. Home Affairs says: “Police certificates are valid for 12 months from the issue date.” It adds: “We may ask you to provide a new police certificate if you have returned to the country after your previous certificate has expired.”
That is a rule about the certificate, not about the English. When you get a new certificate, it has at least a new issue date, and the old translation does not describe it. A fresh translation of the old certificate does not change its issue date. Order the new translation once the new certificate is in your hands; the police certificate translation page has the rest.
Other offices may set their own limit on how recently a document was issued. If a form asks for a recently issued document, ask the office which date it counts and how recent is recent enough.
When you need a new translation, and when you do not
Same document, nothing changed, another application. The translation still describes it. One authority has written about re-use: in its advice for people applying from overseas, where it explains that “Your local embassy or consulate will check any translated documents”, the Australian Passport Office adds: “You can use your translated documents again for any future passport applications. You won’t need new translations made in Australia.” For any other office, ask it before you order again.
A renewed or replaced document. A renewed licence card or a new passport carries new dates, and often a new number, so it is a different document. The translation of the old one does not describe it. The driver licence translation and passport translation pages say what that means for each.
A reissued, amended or annotated certificate. If the registry has issued a fresh copy, corrected an entry or added a note in the margin, the version you hold now is not the one that was translated. Have the current one translated.
Pages added since. A translation covers the pages you sent at the time. Visas and entry stamps added to a passport afterwards, or a back page you did not photograph, are not in it.
Changed details. If your name or other details have changed and the new version of the document shows it, that document needs its own translation. A translation always matches its original; it never updates it.
A different option. If you ordered a Standard translation and a new office asks for a NAATI-certified translator, the old PDF carries no certification statement and no stamp. That is a new order under the NAATI certification option. What each option costs is on what NAATI translation costs.
What you keep, and what we do if you need it again
We deliver your translation by email as a PDF, and it is yours to keep and use again. Under the NAATI certification option it carries the translator’s certification statement, their NAATI stamp (normally the digital one, with a QR code), their name and their practitioner number. What a certified translation looks like goes through it page by page.
Keep the PDF somewhere you will find it in a year’s time, and keep it with the original. If an office wants paper, PDF or hard copy? covers printing it at a size the QR code still scans.
If you lose it, email us with your order number. Our terms say: “We re-send your finished translation on request at no charge.” We keep the finished translation until you ask us to delete it, as our Privacy Policy sets out. Your document photos are deleted within 90 days of delivery, so a new translation of a changed document starts with new photos.
If you find an error in our translation, email us with your order number and we correct and re-issue it at no charge. A document that has changed since we translated it is not an error in the translation; it is a new document, and a new order.
