Apostille vs. Notarization: What's the Difference?
Notarization verifies a signature; an apostille authenticates a document for use in another country. Here's when you need each, and when you need both.
Notarization and an apostille do two different jobs. Notarization verifies the identity and signature of the person signing a document. An apostille authenticates the document itself so it’s legally recognized in another country under the Hague Convention. You often need both: a document is notarized first, then apostilled.
People mix these up constantly, and using the wrong one means a rejected document and a wasted trip. Here’s the difference in plain terms.
Key Takeaways
- Notarization = a notary confirms who signed and that they signed willingly.
- Apostille = a government authenticates the document for international use.
- Apostilles apply between Hague Convention countries; others need embassy legalization.
- Many documents need both, usually notarization first, then apostille.
- Neither one checks the document’s content or any translation’s accuracy.
What notarization does
A notary public is a state-appointed official who witnesses signatures. When a document is notarized, the notary confirms the signer’s identity, that they signed willingly, and applies a stamp and signature. Notarization says nothing about whether the document’s contents are true, only that the signature is genuine.
This is the model US authorities most often use. Our notarized and sworn translation service covers cases where a translation’s certifier signs in front of a notary.
What an apostille does
An apostille is a certificate, recognized by all Hague Convention member countries, that authenticates the origin of a public document, confirming the signature and seal on it are genuine. It’s issued by a designated authority, such as a Secretary of State in the US or the FCDO in the UK.
Once a document carries an apostille, member countries accept it without further authentication. Our apostille and legalization service handles the full process.
When you need which
| Situation | What you need |
|---|---|
| Signing an affidavit for use in the US | Notarization |
| Using a US birth certificate in Spain | Apostille |
| A notarized power of attorney for use in Germany | Notarization then apostille |
| Documents for a non-Hague country | Embassy / consular legalization |
Consider Elena, who needed her US marriage certificate recognized in Italy. She had it notarized, assuming that was enough, then learned at the consulate that Italy required an apostille on the state-issued certificate, not a notarization. The mix-up cost her two weeks. Knowing the destination’s rule first would have saved the trip.

Where translation fits in
Neither notarization nor an apostille checks a translation’s accuracy, so if your document is going to a country that speaks another language, you’ll usually also need a certified translation. The order matters: sometimes the original is apostilled first and then translated, sometimes the reverse. For US immigration specifically, see our guide to certified translation for USCIS.
The bottom line
Notarization verifies a signature; an apostille authenticates a document for international use. Many cross-border documents need both, plus a certified translation. Confirm your destination country’s requirement before you start, and handle the steps in the right order.
