Legalization of Documents and Apostille

In today’s increasingly globalized world, it is common to use documents issued in one jurisdiction in other jurisdictions. For a jurisdiction to accept and utilize documents from another jurisdiction appropriately, these documents must undergo a legalization process to be formally recognized. We provide comprehensive information on document legalization and facilitate all necessary actions with the competent authorities.

What is an Apostille?

An apostille is a certification that authenticates public documents. It is a formal process by which a competent authority of a state verifies and certifies the signature on a public document, the capacity of the signatory, and, when applicable, the authenticity of any seal or stamp on the document.

Types of Documents That Can Be Legalized by an Apostille

Only public documents, including authentic documents and authenticated private documents, can be legalized with an apostille. Authentic documents are those prepared in accordance with legal formalities by public authorities within their jurisdiction, or by a notary or other public official acting within their designated scope. Private documents are considered authenticated when they are validated by the parties before a notary, according to the stipulations of notarial laws.

How to Legalize Documents in Countries That Are Part of the Hague Convention

For a document issued in a state that is a signatory to the Hague Convention, established on October 5, 1961 (which includes countries from Europe, America, the Middle East, Africa, and the Asia-Pacific region), to be valid and accepted in another state that is also a signatory, it must receive an apostille. We provide comprehensive support services for obtaining apostilles from the officially recognized authorities.

How to Legalize Documents in Countries That Are Not Party to the Hague Convention

Documents issued in countries that are not signatories to the Hague Convention cannot be apostilled. In this case, the documents are considered valid and can be accepted as long as the signature of the public official is recognized by a diplomatic or consular agent. We offer full support services for the process of legalizing documents with diplomatic or consular agents.
