What is Apostille?
The Apostille is a form of international document authentication, it is a one-page certificate issued by authorities at the state or Federal level validating the seal and signature of the official on the document. The certificate contains a seal by the Secretary of State or the US Department of State where applicable.
As per the Hague Convention of 1961, there is a list of countries which require a document to go through the Apostille process prior to being presented. If your document falls under the Apostille process, you will have to obtain the Secretary of State Apostille certification or the US Department of State Apostille in Washington DC, depending on the type of document.
It is similar to consular authentication, but it is a simpler process and is used in countries that are part of the Hague Convention of 1961. The Apostille is recognized by all countries that are part of the Hague Convention.
What is Document Authentication?
For countries which are not signatories to the Hague Convention of 1961, documents are required to go through the authentication process certifying the authenticity of the document before being presented in the country of use. Authentication is the process of authenticating documents for use outside the country of origin. It’s a form of authentication that is required by many countries before allowing foreign documents to be used in their legal system. It’s also known as consular authentication or embassy legalization.
The process of consular authentication involves verifying the authenticity of a document and confirming that it meets the requirements of the country where it will be used. Although the first steps are similar to the Apostille process, the authentication process does require an additional step of Embassy Legalization by the Embassy of the country in which the document will be presented. After obtaining the US Department of State certification, it is needed to present your document to the Embassy of the respective country to obtain their authentication stamp. This will be the final step, completing the process.
The Difference Between Authentication and Apostille
The country in which the document will be used determines the type of certificate needed:
- An apostille is for documents to be used in countries that participate in the 1961 Hague Convention Treaty.
- Authentication certificates are for documents to be used in countries that do not participate in the 1961 Hague Convention Treaty.
Consular authentication is a more complex process than an apostille. It involves verifying the authenticity of the document, verifying the signatures on the document, and attesting that the document is valid. In addition, the documents that require consular authentication are typically more complex than those that require apostille, and the process of obtaining the consular authentication stamp is more time-consuming. Another difference between these two procedures is the cost. Apostille is usually a less expensive process.
What Documents Need Authentication?
The documents that require consular authentication vary from country to country. Generally, documents such as birth and marriage certificates, business contracts, power of attorney, legal documents, and educational documents are the most common documents that require consular authentication.

Once this has been deciphered, then the document needs to be viewed by the embassy in the country of origin.
The Authentication procedure consists of getting a document certified through the chain authentication process which consists of: 1. Secretary of State certification; 2. US Department of State certification/attestation/apostille; 3. Legalization of documents from foreign Embassies in the USA.
