    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.

    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. Beginning February 28, 2027, a single apostille will suffice.
