Apostille vs. Notarization: What’s the Difference?
If you're preparing an important document, especially one that will be used outside the United States, you may hear that it needs to be notarized, apostilled, or both. Although these processes are related, they serve very different purposes.
Understanding the difference between an apostille and notarization can help you prepare your documents correctly, avoid unnecessary delays, and determine which services you actually need.
What Is Notarization?
Notarization is a process performed by a commissioned notary public. Depending on the notarial act, the notary verifies the identity of the person appearing, witnesses or confirms a signature, or administers an oath or affirmation.
For a typical notarization, the notary may:
Verify the signer's identity
Confirm the required personal appearance
Witness a signature when required
Administer an oath or affirmation for a jurat
Complete the appropriate notarial certificate
Apply the notary's signature and official seal
Notarization helps deter fraud, but it does not mean that the notary has approved the document's contents or provided legal advice about the transaction.
What Is an Apostille?
An apostille is a certificate issued by a designated government authority that authenticates the origin of a public document for international use under the Hague Apostille Convention.
An apostille can certify the authenticity of:
A signature
The capacity in which the person signing acted
A seal or stamp appearing on the document
An apostille does not certify that everything written in the underlying document is true. Instead, it authenticates the official signature, seal, or authority associated with the document.
The Main Difference
The easiest way to understand the difference is:
Notarization relates to the notarial act involving the signer and document.
An apostille authenticates the origin of a qualifying public document for international use.
In some cases, notarization is the first step and an apostille follows afterward.
When Do You Need Notarization?
Documents that may require notarization include:
Powers of Attorney
Affidavits
Travel consent forms
Real estate documents
Business agreements
Authorization letters
Certain estate-planning documents
Sworn statements
Whether notarization is required depends on the document and the organization receiving it.
When Do You Need an Apostille?
An apostille may be needed when a qualifying U.S. document will be presented in another country where the Hague Apostille Convention applies.
Common examples include:
Birth certificates
Marriage certificates
Death certificates
Diplomas and transcripts
Powers of Attorney
Corporate records
Court documents
Background checks
Adoption documents
The exact process depends on the document's origin and the destination country.
Do All Apostille Documents Need to Be Notarized First?
No. This is one of the most common misunderstandings about apostilles.
Some privately created documents may need to be notarized before they can receive an apostille.
However, government-issued records such as certain birth, marriage, and death certificates generally need an appropriate certified copy rather than notarization of a photocopy.
Determining the document type before beginning the process can help prevent delays.
Can a Notary Issue an Apostille?
No. A notary public does not issue the apostille certificate.
A professional notary or apostille service may assist with preparing and submitting eligible documents, but the actual apostille is issued by the appropriate designated government authority.
For many state-issued or notarized documents, this is the appropriate Secretary of State. Certain federal documents follow a federal apostille process.
What If the Destination Country Doesn't Use Apostilles?
If the Hague Apostille Convention does not apply between the issuing and destination countries, the document may need to go through a different authentication or legalization process.
That process can involve additional government certification and, depending on the destination, an embassy or consulate.
This is why knowing where the document will be used is one of the first questions to answer.
Example: A Power of Attorney for Use Abroad
Suppose you're signing a Power of Attorney in California that will be used overseas.
The process might involve:
Properly completing the Power of Attorney.
Having the required signature notarized.
Submitting the notarized document to the appropriate authority for an apostille.
Completing any translation or additional requirements imposed by the receiving authority.
In this situation, notarization and apostille are separate steps, but both may be required.
How a Notary and Apostille Service Can Help
Working with a professional who handles both notary and apostille services can make the process easier.
Depending on your documents, assistance may include:
Completing the required notarization
Reviewing documents for common preparation issues
Identifying the appropriate apostille process
Submitting eligible documents to the appropriate authority
Helping reduce mistakes that could delay processing
This can be particularly helpful when you're facing an international deadline.
Final Thoughts
Notarization and apostille services are related, but they are not interchangeable. Notarization involves completing a notarial act, while an apostille authenticates the origin of a qualifying document for use abroad under the Hague Apostille Convention.
Some documents require only notarization, some require an apostille without prior notarization, and others require both.
