Apostille vs Notary

When preparing documents for use in another country, you may be asked to provide a notarized document, an apostille, or both. Although these terms are often confused, they serve different purposes. Understanding the difference between an apostille and notarization can help you identify the correct procedure for your document, avoid unnecessary steps, and check the requirements of the country or institution receiving it.

Key Takeaways

  • Notarization involves a notary public performing an authorized notarial act, such as witnessing a signature or taking an acknowledgment.
  • An apostille authenticates the origin of a qualifying public document or notarial certificate for use under the Hague Apostille Convention.
  • A notarized document may still need an apostille before it can be accepted abroad.
  • Not every document needs notarization before apostille authentication.
  • The appropriate procedure depends on the document, its issuing authority, and the destination country's requirements.
  • An apostille does not certify that the contents of a document are true or accurate.

Apostille vs Notary: The Key Difference

The main difference is that notarization concerns a notarial act, while an apostille authenticates the origin of a qualifying document or notarial certificate. One does not automatically replace the other.

Feature

Notarization

Apostille

Purpose

Records or performs a notarial act

Authenticates the origin of a qualifying public document or notarial certificate

Who performs or issues it?

An authorized notary public

A designated competent authority

What does it establish?

Depends on the notarial act, such as an acknowledgment or jurat

The relevant signature, the capacity in which the signer acted, and the identity of the seal or stamp where applicable

When is it relevant?

When a document or signature requires a notarial act

When a qualifying document needs authentication for use under the Hague Apostille Convention

Is it sufficient for international use?

Sometimes, depending on the recipient's requirements

Often used when the Convention applies and an apostille is required

Does it verify the document's contents?

Not automatically

No; it authenticates origin rather than the truth of the contents

For example, a person signing a power of attorney for use abroad may need to have the signature notarized. The receiving authority may also require an apostille on the resulting notarial certificate.

However, an official birth certificate may follow a different authentication route. The correct process depends on the document's origin and the requirements of the receiving authority.

What Is Notarization?

Notarization is a formal act performed by a notary public who is authorized under applicable law. Depending on the type of notarial act, the notary may verify a signer's identity, witness a signature, administer an oath, or take an acknowledgment.

Notarization can help establish that a particular formal act occurred. It does not automatically establish that every statement in the document is accurate or that a foreign government will accept the document.

Example: Notarizing a Power of Attorney

Suppose you prepare a power of attorney authorizing another person to handle a matter on your behalf in another country. The recipient may require you to sign the document before a notary public.

If the document will be used internationally, notarization may be only one step. The recipient may also require an apostille or another form of authentication.

The exact requirements should be confirmed before signing or submitting the document.

What Is an Apostille?

An apostille is a certificate issued by a designated competent authority under the framework of the 1961 Hague Apostille Convention. It authenticates the origin of a qualifying public document so that the document can be presented in another country where the Convention applies.

An apostille generally confirms the authenticity of the signature on the document, the capacity in which the person signing acted, and the identity of the seal or stamp, where applicable. It does not certify the accuracy of the document's contents or guarantee acceptance by the receiving institution.

Example: Apostille for an Official Document

Imagine that you need to submit an official birth certificate to an authority in another country. The receiving authority may require an apostille, but you generally cannot assume that notarizing a photocopy will satisfy that requirement.

The appropriate route depends on how the birth certificate was issued, the competent authority responsible for authentication, and the destination country's rules.

Do You Need a Notary, an Apostille, or Both?

The correct choice depends on what the receiving organization requires and how your document was created or issued. Do not assume that every international document needs both procedures, or that notarization alone is sufficient.

Use these steps to determine what to check:

  1. Identify the document. Determine whether it is a private document, such as a power of attorney, or an official public record, such as a birth certificate.
  2. Confirm the destination. Identify the country where the document will be used and check whether the Hague Apostille Convention applies to the relevant relationship between the countries.
  3. Check the recipient's instructions. Ask the university, employer, government agency, court, or other organization whether it requires notarization, an apostille, translation, or another form of authentication.
  4. Identify the competent authority. The appropriate authority may depend on the document's issuing jurisdiction and whether it is a state or federal document.
  5. Complete any required preliminary steps. Certain private documents may need notarization before the notarial certificate can be apostilled. Other documents may need certification by their issuing authority first.

If the destination does not use the Apostille Convention for the relevant document, an authentication certificate and additional legalization may be necessary.

Examples: Which Process Might Your Document Need?

Different documents can follow different authentication pathways. The following examples illustrate common situations; they are not universal requirements.

1. Power of Attorney

A power of attorney is generally a private document authorizing someone to act on another person's behalf. The destination authority may require the document to be signed before a notary public and then authenticated with an apostille.

Other requirements may apply depending on the jurisdiction and the intended use of the document. Confirm the required wording, signing procedure, and authentication route before signing.

2. Birth or Marriage Certificate

Official birth and marriage certificates are usually issued by a government authority. Depending on the issuing jurisdiction, the original record or an eligible certified copy may need to be submitted through the appropriate authentication process.

Notarizing a photocopy does not automatically authenticate the underlying government record. Check which version of the certificate the recipient accepts and which authority is responsible for authenticating it.

3. Diploma or Educational Document

A foreign university, employer, or licensing organization may request an apostilled educational document. The required process can vary: some documents may need verification by the issuing institution or another designated authority before an apostille can be issued.

Do not assume that a notarized photocopy of a diploma will meet the recipient's requirements. Ask whether the recipient needs the original document, an official transcript, an institutional certification, or another form of verification.

How the U.S. Apostille Process Depends on Your Document

In the United States, the authority responsible for authentication depends on the document's origin and the applicable rules. There is no single apostille office that handles every document.

  • State-issued documents: Documents originating at the state level commonly follow the authentication procedure established by the relevant state authority, often the Secretary of State.
  • Federal documents: Qualifying documents issued or certified by federal agencies may require authentication through the U.S. Department of State.
  • Notarized private documents: These may need a valid notarial certificate and any required state-level authentication before an apostille can be issued.
  • Documents for non-Convention destinations: An authentication certificate and additional legalization may be required instead of an apostille.

The precise route depends on the document and destination. Before sending original documents or paying for a service, review the U.S. Department of State's apostille guidance and the relevant issuing state's official instructions.

Common Mistakes to Avoid

Small misunderstandings can lead to rejected documents, extra expenses, or delays. Avoid these common mistakes:

  • Assuming notarization and an apostille are interchangeable. They serve different purposes.
  • Getting a document notarized unnecessarily. Some official records follow a direct authentication route.
  • Sending the document to the wrong authority. State and federal documents may require different procedures.
  • Assuming an apostille verifies the contents. It authenticates the relevant origin details, not the truth of the document.
  • Ignoring translation requirements. The receiving institution may require a certified translation or other language-specific documentation.
  • Assuming every country follows the same rules. Verify the destination's applicable requirements before starting.
