Why it exists
Before 1961, a public document from one country was only recognized in another after a chain of certifications: a local authority, then the national foreign ministry, then the receiving country’s embassy, and sometimes a further ministry on arrival. The Hague Conference on Private International Law drafted a treaty to replace that chain with a single certificate issued by the origin country. It was signed at The Hague on 5 October 1961 and entered into force in 1965.
The United States ratified it in 1980 and the Convention took effect for the U.S. on 15 October 1981. Today it is the most widely ratified of all Hague Conference treaties, with well over 120 contracting parties.
What counts as a “public document”
Article 1 of the Convention lists four categories:
- Documents from a court or an official connected with a court (including prosecutors, clerks and process servers).
- Administrative documents (birth, marriage and death certificates, licenses, government letters).
- Notarial acts.
- Official certificates placed on private documents — such as a registration or a certification of a signature. This is how privately written documents (powers of attorney, contracts, letters) become eligible: a notarial certificate on them is a public document.
Two categories are excluded: documents executed by diplomatic or consular agents, and administrative documents dealing directly with commercial or customs operations. In practice, chambers of commerce documents and consular notarizations follow separate routes.
What the apostille certifies
Article 3 limits the apostille to certifying “the authenticity of the signature, the capacity in which the person signing the document has acted and, where appropriate, the identity of the seal or stamp which it bears.” Article 5 adds that the certificate “shall not be required to be legalised” further. These two sentences explain why a foreign office cannot demand consular legalization on top of an apostille, and also why an apostille is never a statement about the truth of a document’s contents.
Competent authorities
Each contracting party designates its own authorities (Article 6) and notifies the Hague Conference. The United States designated the state Secretaries of State (and equivalents), the clerks and deputy clerks of federal courts, and the U.S. Department of State. The current U.S. list is published by the Hague Conference and is the basis for the state and federal sections of this portal.
The register
Every competent authority must keep a register recording each apostille’s number, date, the name of the signer and the capacity in which they acted (Article 7). A receiving authority can ask the issuing office to verify an apostille against that register, and many offices now offer an online lookup — see how to verify an apostille.
Accession and objections
New countries join by accession. Any existing member may object within six months; if it does, the Convention does not apply between those two countries. Objections are rare but matter in practice: several European countries, for example, objected to accessions in the past and later withdrew the objections. The effective relationships are tracked in the Hague Conference’s status table, which the country directory summarizes for the destinations U.S. documents are most often sent to.
The electronic apostille program (e-APP)
Launched in 2006, the e-APP promotes two things: electronic apostilles (digitally signed certificates issued as PDFs) and electronic registers. A growing number of U.S. states and foreign authorities now issue or accept e-apostilles. See electronic apostilles.
Recent accessions relevant to U.S. documents
- China — in force 7 November 2023 (Hong Kong and Macao were already covered separately).
- Canada — in force 11 January 2024; Canadian provinces issue apostilles for provincial documents.
- Rwanda, Bangladesh, Pakistan — recent accessions expanded the Convention in Africa and South Asia.
- Vietnam — in force 11 September 2026, ending embassy legalization for U.S. documents sent there.

Frequently asked questions
Is the Hague Apostille Convention the same as the Hague adoption or child abduction conventions?
No. The Hague Conference has produced dozens of treaties. The 1961 Apostille Convention deals only with legalization of public documents. Adoption (1993) and child abduction (1980) are separate conventions with separate rules.
Can a country refuse an apostille from the U.S.?
A contracting party must accept apostilles issued by a U.S. competent authority as sufficient proof of the signature, capacity and seal. It may still refuse the document for other reasons — content, age, missing translation — but not for lack of consular legalization.
Does the Convention apply between the U.S. and every member?
Almost. The Convention applies between the U.S. and every state that has acceded without a U.S. objection, and the U.S. has not objected to any accession. A few member pairs elsewhere have objections in place.
