What is an Apostille? Apostille vs. Notarization Explained
If someone told you that you need an apostille and you have no idea what that means, you are not alone. Most people have never heard the word until a lawyer, a foreign embassy, or a government agency tells them they need one. This post breaks down exactly what an apostille is, how it differs from a notarization, and how to figure out which one your document actually requires.
What Is a Notarization?
A notarization is a certificate that authenticates a document by verifying the signature of the individual who signed it.
When a notary public witnesses a signature, they are confirming the identity of the signer and attesting that the signature is genuine.
Notarial certificates are widely recognized within the United States.
Banks, courts, government agencies, and businesses rely on them every day. But there is a limitation that most people don't discover until they need to use a document abroad — foreign countries do not recognize the legal authority of local notaries.
What Is an Apostille?
An apostille is a certificate that authenticates a document by verifying the signature of the public official who signed it.
Apostilles are recognized internationally by countries that are members of the Hague Convention, an international treaty that standardizes how documents are authenticated across borders.
Because notaries are commissioned public officials, an apostille can be used to authenticate a notarized document for use abroad.
But for documents already signed by a government official — like a birth certificate, marriage certificate, or death certificate — a notarial certificate is not necessary.
This is why an apostille is not simply a "stronger" notarization. They are two different tools that serve two different purposes.
Apostille vs. Notarization: The Key Difference
The simplest way to understand the difference is this.
A notarization verifies the signature of an individual.
An apostille verifies the signature of a public official.
A notarization is recognized domestically. An apostille is recognized internationally by Hague Convention member countries.
If your document needs to be used in the United States, a notarization is usually what you need.
If your document needs to be used in another country, an apostille is likely what you need — and in some cases, both a notarization and an apostille are required, in that order.
How Do You Know Which One You Need?
Most people don't figure this out on their own. In my experience, clients typically come to me after an attorney, a foreign embassy, a bank, or a government agency has already told them they need an apostille.
They arrive knowing they need something but not always sure what the process looks like.
When a client isn't sure what their document requires, I ask them five questions.
Who created the document?
Where was it created?
Where will it be used?
What language is it in?
Who signed it?
The answers to those questions determine everything — which authority handles the apostille, whether notarization is required first, and whether a standard apostille is sufficient or whether embassy legalization is needed instead.
An Important Distinction: Vital Records vs. Everything Else
This is where many people make a costly mistake when they try to navigate the apostille process on their own.
For documents that are not vital records — such as a power of attorney, an affidavit, or a personal statement — notarization is often required before an apostille can be obtained. The notary's signature is what the apostille then authenticates.
For vital records — such as a birth certificate, marriage certificate, or death certificate — notarization is not part of the correct process. A vital record is issued and signed by a government official, which means the government is already the appropriate signing authority. Attempting to notarize a vital record before apostilling it can invalidate the document entirely.
Knowing which category your document falls into before you begin can save you significant time, money, and frustration.
State Apostilles vs. Federal Apostilles
Not all apostilles come from the same place. Where your document was issued determines which authority apostilles it.
Documents issued by a California government authority — such as a county-issued birth certificate or a notarized document signed by a California notary — are apostilled through the State of California.
Some documents require a federal apostille, issued through various federal government offices in Washington D.C. This is common for documents issued at the federal level, such as FBI background checks or documents signed by federal officials.
In some cases, a client may need both. I helped a naturalized citizen born in France obtain both state and federal apostilles for documents he needed for an upcoming immigration appointment. Each document had a different issuing authority, which meant a different apostille process for each one.
Having someone coordinate that on your behalf — and get it right under a deadline — made a meaningful difference in how that appointment went.
What If the Destination Country Doesn't Accept Apostilles?
Not every country is a member of the Hague Convention. For documents headed to non-member countries, a standard apostille is not sufficient. Those documents require a different process called embassy legalization or authentication, which involves additional steps through the U.S. Department of State and the destination country's consulate.
This is one more reason why knowing the destination country upfront is essential. Our Los Angeles apostille service page covers the full range of services available depending on where your documents are headed. Our booking page has details about speed and cost.
A Quick Reference: Apostille vs. Notarization
To summarize the key differences before you reach out:
Notarization verifies the signature of an individual signer and is recognized domestically
An apostille verifies the signature of a public official and is recognized internationally by Hague Convention member countries
Vital records do not require notarization before apostilling
Non-vital records often do require notarization before apostilling
Some documents require both a state and a federal apostille
Countries outside the Hague Convention require embassy legalization instead of an apostille
The Bottom Line
An apostille is not a notarization, and a notarization is not an apostille. They serve different purposes, are issued by different authorities, and are recognized in different contexts. Knowing which one your document requires — and in what order — is the difference between a smooth process and an expensive mistake.
