A Washington Apostille is an official certification that validates Washington State public documents for use in Hague Convention countries. Issued by the Washington Secretary of State’s Office, it confirms the authenticity of signatures, stamps, and seals on documents. This simplifies cross-border document use and is essential for anyone using Washington paperwork abroad.
What is a Washington Apostille? It’s part of the 1961 Hague Convention’s simplified authentication system. The certificate is a small rectangular sticker attached to your original or certified document. It only verifies the document’s legitimacy, not its content. This eliminates the need for further embassy or consulate legalisation in member countries.
