Apostille, Notarization, or Certified Copy: Which One Do You Actually Need?
Three different things that people constantly mix up. What each one certifies, who issues it, and how to tell from the request which one the agency is asking for.
Someone tells you they need a "certified" or "official" copy of your document, and you end up guessing. Here's what each of these three things actually is, so you can tell from the request which one is being asked for.
Notarization certifies a signature
A notary public verifies that the person signing is who they claim to be, that they're signing willingly, and that they understand they're signing. Then the notary records it in a journal and attaches a certificate.
What it does not do: a notary does not certify that the contents of a document are true, that it's legally valid, or that it will accomplish what you want. A notarized lie is still a lie, it's just a lie with a verified signature.
Who issues it: any commissioned notary public. In California the fee for most notarial acts is capped by law at $15 per signature.
When you need it: documents you write and sign yourself. Powers of attorney, affidavits, consent letters, deeds, trust documents.
A certified copy comes from whoever issued the original
A certified copy is issued by the record's custodian. A county recorder, a state registrar, a court clerk. it carries their seal confirming it's a true copy of what's on file.
The critical point: in California, a notary generally cannot make a certified copy of a vital record. Only the issuing authority can. This trips people up constantly: they take a birth certificate to a notary, get the photocopy notarized, and discover it's worthless for the purpose they needed it for.
Who issues it: the county recorder, the California Department of Public Health, a court clerk, or the school or agency that created the record.
When you need it: birth, marriage, and death certificates, divorce decrees, court orders, academic records. Any time the underlying record was created by an agency rather than by you.
An apostille certifies the official who signed
An apostille is a certificate attached to a document that makes it recognizable in another country. It verifies that the signature, seal, or stamp on the document. The notary's, or the county registrar's, is genuine.
What it does not do: it doesn't say anything about whether the document's contents are true, and it doesn't work for every country. It only works between Hague Apostille Convention members.
Who issues it: the California Secretary of State for state and county documents, the U.S. Department of State for federal documents.
When you need it: any time a U.S. document is going to be used by a government, court, school, or employer in another Hague member country.
How they stack
These aren't alternatives to each other, they build on each other.
- You sign a power of attorney → notarization → apostille (certifying the notary) → send abroad.
- You need your birth certificate abroad → certified copy from the county → apostille (certifying the registrar) → send abroad.
Notice that the second chain has no notarization in it at all. Adding one doesn't help and doesn't make the document more official, it just costs you a step.
Reading the request
| If the request says… | They almost certainly want… |
|---|---|
| "Notarized copy" of a birth certificate | A certified copy from the county. This phrasing is common and technically incorrect |
| "Official" or "long form" birth certificate | A certified copy from the issuing authority |
| "Apostilled" or "legalized" document | An apostille, or consular legalization if the country isn't a Hague member |
| "Sworn" statement or affidavit | Notarization with a jurat. You'll be placed under oath |
| "Acknowledged" signature | Notarization with an acknowledgment. No oath |
When you're not sure
Ask the agency requesting it. They know what they'll accept, and getting it in writing from them beats guessing. If you can't get a straight answer, bring the document and the request to me. Working out which of these three you need takes a few minutes and it's free.
