What Is an Apostille?

Hague Conference on Private International Law

An apostille is a certificate issued for documents that will be used in countries that are members of the Hague Apostille Convention (formally known as the Hague Convention of 1961).

The apostille certifies:

• The authenticity of the signature
  
  

• The capacity in which the person signing the document acted
  
  

• The identity of the seal or stamp on the document
  
  

Once a document has an apostille, it is legally recognized in all member countries of the Hague Convention.

Common Documents That Require an Apostille

• Birth certificates
  
  

• Marriage certificates
  
  

• Death certificates
  
  

• Divorce decrees
  
  

• Power of attorney
  
  

• Corporate documents
  
  

• FBI background checks
  
  

• Diplomas and transcripts
  
  

• Notarized affidavits
  
  

If the destination country is part of the Hague Convention, you need an apostille — not authentication.

What Is Authentication?

Authentication is a more detailed certification process required when documents are being sent to countries that are NOT members of the Hague Apostille Convention.

Instead of a single apostille certificate, authentication typically involves multiple steps:

1. Notarization (if required)
   
   

2. Certification by the Secretary of State
   
   

3. Authentication by the U.S. Department of State
   
   

4. Legalization by the foreign embassy or consulate
   
   

U.S. Department of State

This process is sometimes called consular legalization and can take longer than obtaining an apostille.

The Most Important Question:

Is the destination country a Hague Convention member?

• If YES → You need an apostille.
  
  

• If NO → You need authentication and consular legalization.
  
  

How Do You Know Which Countries Are Hague Members?

You can verify whether a country is a member of the Hague Apostille Convention through the Hague Conference on Private International Law website or by consulting a professional apostille service provider.

Apostille vs. Authentication: Final Thoughts

The difference between apostille and authentication comes down to one key factor:

👉 Is the destination country a member of the Hague Apostille Convention?

• Hague country = Apostille
  
  

• Non-Hague country = Authentication + Consular Legalization
  
  

Understanding this distinction helps you avoid delays and ensures your documents are legally recognized overseas.
