Hague Apostille Convention 2026: 130 Contracting Parties, and What It Means for Swedish Documents

How many countries are in the Hague Apostille Convention in 2026?

There are 130 contracting parties to the Convention of 5 October 1961 Abolishing the Requirement of Legalisation for Foreign Public Documents. This figure comes from the official status table maintained by the Hague Conference on Private International Law (HCCH), last updated on 30 June 2026 — the date Thailand's accession pushed the count to 130. The number is not fixed and keeps moving. Any country list published on a website, including this one, is a snapshot. See the complete country-by-country list, grouped by region, in our Hague Apostille Countries List 2026.

Which countries joined most recently?

• Algeria. The Convention entered into force for Algeria on 9 July 2026, following its accession deposited on 5 November 2025. Documents sent to Algeria before that date required full consular legalisation. Documents used on or after that date can rely on a single apostille.
• Thailand. Thailand deposited its instrument of accession on 30 June 2026, becoming the 130th contracting party the same day. The Convention will enter into force for Thailand on 28 February 2027. Until that date, documents bound for Thailand still require full consular legalisation.
• Vietnam. Vietnam deposited its instrument of accession on 31 December 2025. The Convention is expected to enter into force for Vietnam on 11 September 2026. Until that date, consular legalisation is still the correct route for Vietnamese-bound documents.

What is the difference between "contracting party" and "in force"?

These are two different things, and confusing them causes rejected documents. A country becomes a contracting party when it deposits its instrument of accession, ratification, acceptance or approval. The Convention then enters into force for that country sixty days later, unless an existing member raises an objection within a six-month window. The HCCH status table shows both dates in separate columns. A country can appear on the list of contracting parties while the Convention is not yet in force for it — Thailand and Vietnam are both in exactly that position right now. The practical rule: check the entry-into-force date against the date your document will actually be used, not the date you order the apostille.

Does membership guarantee an apostille will be accepted?

No. Article 12 of the Convention allows an existing member to object to a new state's accession. Where an objection stands, the Convention does not take effect between those two specific countries, and the traditional legalisation route applies between them, even though both appear on the same membership list. Germany's standing objection to India's accession is the best-known example. Objections can also be withdrawn: the Netherlands withdrew its objection to Senegal's accession on 28 January 2026, and the Convention took effect between the two countries from that date. So membership is a country-pair question, not a single-country question. Both the issuing country and the destination country matter.

What this means for documents issued in Sweden

Sweden has been a contracting party since 1999. An apostille issued in Sweden is valid in the other 129 contracting parties, subject to the entry-into-force and objection points above. Three points:

1. In Sweden, the apostille is issued by a Notarius Publicus, a notary public appointed by the County Administrative Board, not by a ministry or central authority as in many other countries.
2. Private documents need a notarial act first — a board resolution, a power of attorney or a commercial contract is not a public document in itself and has to be notarised before it can carry an apostille. Public records such as personbevis or Bolagsverket extracts can be apostilled directly.
3. A Swedish apostille does not certify content. It confirms the authenticity of the signature, the capacity of the signatory and the identity of the seal — it says nothing about whether the document is true. Destination authorities may still impose their own translation or format requirements on top.

How to verify a country's status before sending documents

The authoritative source is the HCCH status table for Convention No. 12. Before committing to a route, check three things: is the destination country listed as a contracting party, is the Convention in force for that country on the date the document will be used, and is there a standing objection between the destination country and Sweden. If any of the three fails, the apostille route does not apply and the consular legalisation chain is needed instead: notarisation, then authentication, then embassy attestation.
