Do NAATI translations expire? The "valid to" date on the stamp, explained

Every week, someone emails us in a mild panic: "My NAATI translation says valid to March 2027. Does that mean I have to get it redone before then?"

Short answer: no. Your translation doesn't expire. But the confusion is completely understandable, because there's a date printed right there on the stamp. Here's what it actually means.

The "valid to" date is about the translator, not your document

All credentials issued under NAATI's current certification system have a 3-year validity period, meaning translators need to recertify to maintain their credential. The date you see on the stamp is that recertification deadline for the translator, a professional requirement that keeps their skills current. NAATI

NAATI's official position is that the "valid to" date on a stamp refers to the recertification or potential expiry of the practitioner's credential at the time the stamp was issued, and does not reflect a date after which a translation becomes invalid or unacceptable. NAATI

Think of it like a doctor's certificate: the doctor's registration needs periodic renewal, but a medical certificate they signed last year doesn't retroactively become invalid when their registration comes up for renewal.

So how long is a NAATI translation valid?

Indefinitely. A translation from a NAATI-credentialed translator includes the date it was completed, and the translation remains valid without any expiry. NAATI's view is that it must be accepted wherever it's presented, provided the translation date falls within the translator's credential period. NAATI

That last part is the one rule that matters: the translator must have held a valid credential on the day they completed your translation. A reputable service handles this for you, but you can always double-check. NAATI has a free credential verification tool on its website, and newer digital stamps carry a QR code you can scan to verify the credential directly.

The three cases where you actually need a new translation

The translation itself never expires, but sometimes the situation around it does.

1. The original document expires. A police check is the classic example: Home Affairs generally wants police clearances issued within the last 12 months. When your police check goes stale, the translation goes stale with it. Not because the translation expired, but because you now need a fresh original, which needs its own fresh translation. Same logic for driver's licences: if your original licence carries an expiry date, the translation reproduces that same information, so it effectively runs out when the licence does.

2. The original document changes. New passport, name change after marriage, an updated academic transcript with your final semester added. Any change to the source document means the old translation no longer matches it.

3. A specific institution asks for a recent one. Some institutions may request a more recent version if the document is time-sensitive or if formats and terminology have changed since the original translation was done. This is rare, and it's the institution's own policy rather than a NAATI rule. For Australian visa and migration purposes, there's no requirement that a translation be completed within a certain window before lodgement.

What about very old stamps?

If you're holding a translation from years ago, the stamp might look different. Until 2007, NAATI accreditations were issued for life with no expiry date; between 2007 and 2017, they carried revalidation requirements; and the current certification system replaced accreditation entirely in 2017. Translations bearing the older stamps remain valid indefinitely, though if you're re-lodging documents for a new application, it's worth confirming the receiving body is happy with an older format.

The practical takeaway

Before you pay to re-translate anything, run through this checklist:

1. Is the original document still current? If yes, keep going. If it's an expired police check or licence, get a new original first.
2. Has anything on the original changed? If not, your translation still matches.
3. Has the receiving institution specifically asked for a recent translation? If they haven't, you don't need one.

If all three check out, your existing NAATI translation is as valid today as the day it was issued, whatever date is printed on the stamp.
