Apostille and consular legalisation

What an apostille is, and what it replaces

The Convention of 5 October 1961 abolishes the requirement of legalisation for foreign public documents as between its parties, and substitutes a single certificate. The certificate, the apostille, is issued by a competent authority designated by the State in which the document was issued, and it certifies the authenticity of the signature, the capacity in which the signatory acted, and where appropriate the identity of the seal or stamp the document bears. It is placed on the document itself or on an attached allonge, and each competent authority keeps a register of the certificates it has issued, which is what makes an apostille verifiable at its source.

Instrument: Convention of 5 October 1961 Abolishing the Requirement of Legalisation for Foreign Public Documents. Status per the HCCH status table, read on 11 November 2026. Official text located and read.

Note the limits of what it certifies. An apostille says that the document is what it appears to be and that the official who signed it held the office they claimed. It says nothing about whether the contents are true, it does not validate the document's legal effect in the receiving State, and it is not a translation.

What it replaces is a chain. Before the Convention, and still today for documents from a non-party, a foreign public document was accepted only after a series of certifications ending at a mission of the receiving State. The Convention compresses that chain into one certificate issued at the origin.

This is the only part of a citizenship file governed by an instrument Türkiye did not write, which is also why it is the part most often mis-stated in guidance written from the Turkish end.

The consular chain, for a non-party

Where the issuing State is not a party, the document takes the longer route. The sequence is the one recorded against every non-party row in the dataset:

1. The document is obtained and, where the local system requires it, notarised and certified by the competent domestic authority.
2. It is legalised by that country's ministry of foreign affairs.
3. It is then legalised by the Turkish embassy or consulate accredited to that country.

Each step is a separate appointment with its own queue, and the third depends on the second, so the chain cannot be parallelised. That is the practical reason this question has to be answered at the start of a file rather than at the document stage: for a client from a non-party State the legalisation is often the longest single lead time in the whole procedure, and it can be started before the investment is complete.

The status table

Every Contracting Party, with the date the Convention entered into force for it, and the non-party States this site names. Three statuses rather than two, for the reason given below the table.

157 jurisdictions listed: 129 for which the Convention is in force today, 1 which has acceded but for which it is not yet in force, and 27 named non-parties. The HCCH status table gives 130 Contracting Parties, which is the 129 in force plus the 1 pending accession.

The Contracting Party rows are the complete HCCH list. The non-party rows are not a complete list of the world's non-parties: the dataset records a non-party only where this site names that nationality elsewhere. The absence of a State from the table is therefore not a statement that it is not a party, and a State not listed here should be checked against the HCCH status table directly.

The case a yes-or-no field gets wrong

Thailand has acceded to the Convention, and the Convention enters into force for it on 28 February 2027. Until that date a document issued there still needs consular legalisation, even though every list of Contracting Parties already includes it, and the HCCH status table itself counts it among the 130 parties.

Our dataset therefore records it with the member field false and the entry-into-force date set, which looks inconsistent and is not. The field answers the operational question, which is what a document from there needs today, rather than the treaty question, which is whether the State has acceded. A dataset with only a boolean cannot answer both, and the one practitioners need is the operational one.

The interval between accession and entry into force is a matter of months rather than days. A file planned on a list that collapses the two will instruct an apostille that the issuing authority cannot yet issue.

Türkiye's own position

The Convention entered into force for Türkiye on 29 September 1985, which has two consequences for a file. A foreign apostille is accepted in Türkiye on its own, with no further Turkish consular step, and that is the whole saving the Convention delivers here. In the other direction, a Turkish public document needed abroad can be apostillised rather than legalised, which matters for the certificate of conformity, a title deed extract or a Turkish civil status record used in another jurisdiction.

Which Turkish authorities are designated as competent to issue apostilles is published by the HCCH in its competent-authority listing, which is a different table from the status table our register indexes. We have not read the designation for this release and do not reproduce it here, because naming the wrong office is worse than naming none.

Sworn translation and notarisation, after legalisation

Legalisation makes a foreign document usable. It does not make it readable, and the Turkish authority that will act on it needs it in Turkish. That is a separate step, and in a file it is a separate failure point:

• Order. Legalise first. The translation has to be made of the document as certified, so that the apostille or the consular legalisations are part of what is translated and certified. A translation obtained earlier, on a trip home before the apostille was applied for, will not match the document that arrives.
• Who translates. A sworn translator, whose translation is then certified by a Turkish notary. A translation certified at a Turkish consulate abroad is the alternative where the document is being assembled before travel.
• Names. This is where files stall, and it is a clerical problem rather than a legal one. A name transliterated one way on the passport, another way on the birth certificate and a third way in the translation produces a file in which the documents do not obviously refer to the same person. The transliteration used in the translations should be fixed once, against the passport, before any of them is ordered.

The sworn translation and notarial certification requirements rest on Turkish notarial legislation, which this site's source register does not yet index, so this section is carried on practice rather than on a cited instrument. We also record no verified rule on how recently a civil status document must have been issued to be accepted: requirements of that kind are applied at the directorates and we have located no instrument setting a period.

Questions this page settles

Does my country’s document need an apostille or consular legalisation?

It depends only on whether the issuing State is a party to the Hague Convention of 5 October 1961 and whether the Convention is in force for it today. The table on this page gives the answer for every Contracting Party, with the date it entered into force. As of 11 November 2026 the Convention is in force for 129 States; documents from those take an apostille, and documents from any other State take the consular chain.

Is a State that has just acceded to the Convention already covered?

No, and this is the case a yes-or-no field gets wrong. Accession and entry into force are different events, separated by months. Thailand has acceded, but the Convention enters into force for it on 28 February 2027, so documents issued there still need consular legalisation until that date. A table with a single member column cannot express this, which is why ours carries the entry-into-force date as well.

How long has Türkiye been a party?

The Convention entered into force for Türkiye on 29 September 1985. That matters in two directions: a Turkish public document for use abroad can be apostillised, and a foreign apostille is accepted in Türkiye without any consular step.

Does an apostille remove the need for a translation?

No. They answer different questions. An apostille certifies the origin of the document, the authenticity of the signature and the capacity of the signatory. It says nothing about the content and is not a translation. A document in a foreign language still has to be translated by a sworn translator and the translation certified, which is a separate step after legalisation and not a substitute for it.

Which order do legalisation and translation go in?

Legalise first, translate afterwards. The apostille or the consular legalisation is applied in the country of origin to the document as issued; the translation is then made of the document together with the certification it now carries. A translation commissioned before legalisation does not cover the certificate that was added later, which is a common cause of a document being sent back.

Which documents are public documents for the purposes of the Convention?

The Convention applies to public documents: documents emanating from an authority or official connected with the courts, administrative documents, notarial acts, and official certificates placed on documents signed by private persons, such as a certificate of registration or an authentication of a signature. It expressly does not apply to documents executed by diplomatic or consular agents, or to administrative documents dealing directly with commercial or customs operations.
