Do I Need Notarized Translation or Certified Translation?

It is one of the most common questions people arrive with, and the confusion is understandable: "certified" and "notarised" get used loosely, sometimes as if they were the same thing. They are not, and the gap between them is money and time. Order a plain certified translation when the office wanted it notarised and you are sent back to start again; pay for notarisation the authority never asked for and you have spent on a step that bought you nothing. The sections below answer the question head-on, then break it into the smaller questions that actually settle your case.

📝 What does "certified" actually mean?

A certified translation is one where a qualified translator signs a formal statement confirming the English version is a complete and faithful rendering of the original. At LingoExpress, that declaration is issued on company letterhead (registered UEN 53491103W) and reads in substance: "We, LingoExpress, a professional translation service provider, hereby certify that the attached document(s) have been translated by our team of qualified and professional translators…" — followed by the translator's name and the date. The point of it is accountability: a named person and a real registered entity stand behind the accuracy of the page, and a receiving officer can see exactly who.

🖋️ What does notarisation add on top?

Notarisation does not replace certification — it sits above it. A Singapore Notary Public verifies the translator's identity, witnesses their signed declaration, and applies a notarial seal. The subtle point to hold onto is what the notary is attesting to: that the certification was properly made and signed, not a fresh word-by-word re-check of the translation itself. The accuracy still rests on the certified translation underneath; the notary adds an official witness to the act of certifying. That is why a notarised translation is always a certified translation plus a layer, never an alternative to one.

🧭 So which one does your case need?

The honest answer is that it depends on who is receiving the document and what they are processing. For many routine matters with the Immigration & Checkpoints Authority (ICA) and other bodies — a foreign certificate that simply needs to be readable in English — a certified translation is accepted. For permanent residence and citizenship, key civil documents such as birth, marriage and divorce certificates are more often expected to be notarised, though this is best treated as commonly required rather than guaranteed. The same document can sit at a different tier depending on the route, so the requirement printed on your own application page is the only source that settles it.

🌏 What about legalisation or an apostille?

There is one tier above notarisation, and it is where the last of the confusion usually lives. Legalisation — issued as an apostille since Singapore joined the Apostille Convention — is where the Singapore Academy of Law (SAL) confirms that the notary who signed your document is genuine and properly registered. The single most useful thing to know: this layer is almost always for documents heading overseas — a Singapore document you will present to a foreign embassy, university or government. For purely local submissions it rarely enters the picture. If your matter has an overseas leg, that is the moment to confirm an apostille genuinely belongs in the chain before you spend on it.

✅ The simplest way to get it right

Rather than guessing, send your document with the name of the application you are filing and have the correct scope confirmed before anything is signed or sealed. LingoExpress issues the certified translation on company letterhead and coordinates the Notary Public in the same job when your route calls for it — so you deal with one provider, at the right tier, the first time. After thousands of certified and notarised jobs for families across Singapore, the team can usually point you to the tier your case needs on first read.
