Apostille or legalization: which one your document needs

A Convention country takes one apostille. Any other country needs the longer consular legalization chain through its embassy.

An apostille is a certificate a designated office attaches to a public document. It answers three questions: whose signature is this, whose seal is this, and did the signer have the authority. It says nothing about whether the content is true. The 1961 Convention created this single certificate so that member countries accept each other's documents without further stamps. The HCCH status table listed 130 contracting parties at its June 2026 update.

Legalization is the older chain for countries outside the Convention. The document is authenticated at home first, then the destination country's embassy or consulate adds its own stamp. Each stamp is a separate queue with its own fee and waiting time. The United Arab Emirates, Qatar, Egypt, Thailand and Malaysia all sit outside the Convention, so documents for those countries travel the full chain.

The destination alone decides which path applies. The issuing office cannot choose for you. A birth certificate from California used in Spain takes one apostille from the California Secretary of State, because Spain is a party. The same certificate used in the Emirates needs California authentication plus UAE consular legalization.

Start by checking membership. Use the checker tool on this site for frequent destinations, or search the HCCH status table for any other country. Then find the issuing office for your document, not for your destination. A document is always certified where it was issued: state papers by the state, federal papers by the federal office, UK papers by the Legalisation Office.

Two mistakes cause most rejections. The first is sending a state document to the federal office or the reverse. The second is sending a photocopy. Offices work from originals or certified copies from the registry. Confirm the fee and the address on the office page on the day you post, because both change without notice.
