    What Is the Hague Convention?

    The Convention of 5 October 1961 Abolishing the Requirement of Legalisation for Foreign Public Documents, commonly known as the Apostille Convention, was established to simplify the authentication of documents between member countries. Before the convention, authenticating documents for international use required a lengthy chain of certifications. Learn how our apostille services help you navigate this process for Hague Convention member countries.

    How It Works

    Member countries agree to recognize a standardized apostille certificate attached to public documents. This single certificate replaces the previously required chain of authentications, making international document verification faster and more straightforward.

    1

    Submit Document

    Provide your original public document for authentication.

    2

    Apostille Issued

    The competent authority verifies and attaches an apostille certificate.

    3

    Accepted Worldwide

    Recognition depends on the Convention being in force and applying between the issuing and destination countries.

    When Embassy Legalization Is Needed

    Where the Apostille Convention does not apply, documents may require authentication followed by embassy or consular legalization. The required steps depend on the document and destination; we confirm them before processing.

    Update: Thailand Joins the Apostille Convention

    On June 30, 2026, Thailand deposited its instrument of accession to the 1961 Hague Apostille Convention, becoming the 130th contracting party. The Convention enters into force for Thailand on February 28, 2027. Until then, documents destined for Thailand still require traditional embassy/consular legalization — which we handle. From February 28, 2027, apostilles can replace embassy legalization where the Convention applies; receiving-authority requirements still need to be confirmed.
