When a Country Joins the Apostille Convention
Table of contents
When a country accedes to the Hague Apostille Convention, the change is not immediate or automatically bilateral with every party. After the Convention enters into force, an apostille replaces diplomatic or consular legalisation for covered public documents between the new party and a party that did not object, where authentication is required.
Key takeaways
- Accession does not make the Convention operational immediately. Under Article 12, entry into force follows a six-month objection period plus 60 days.
- Any existing member can object to the accession, and then the Convention does not apply between those two countries.
- From the in-force date, covered Australian public documents can use a DFAT apostille where Australia and the destination are in a Convention relationship.
- Apostilles do not remove document-specific requirements, translation rules or the need for prior notarisation where the document is not already an eligible public document.
- Always check the HCCH status table on the day you prepare a document, because membership changes.
How does a country join?
A country that was not a party when the Convention was negotiated joins by accession: it deposits an instrument of accession with the Netherlands, which acts as depositary. Existing members are then notified and have six months to raise an objection. If a member objects, the Convention will not apply between it and the acceding country, although it can still apply between the acceding country and every member that did not object.
Article 12 provides for entry into force on the 60th day after the end of the six-month objection period. That is why an accession announcement and its effective date differ by about eight months. Until the effective date, use the route required under the then-current rules. Our guide to how the Hague Apostille Convention works explains the Convention itself.
What have recent accessions looked like?
Recent accessions show the pattern. The dates below were checked against the HCCH status table on 9 October 2026. They illustrate the process but do not replace a fresh check, particularly while an objection period is still open.
| Country | Accession | In force | Note |
|---|---|---|---|
| Pakistan | 8 July 2022 | 9 March 2023 | Several members objected; Australia did not |
| China | 8 March 2023 | 7 November 2023 | Mainland China; Hong Kong and Macau already applied it |
| Canada | 12 May 2023 | 11 January 2024 | Replaced legalisation for Canadian documents |
| Bangladesh | 29 July 2024 | 30 March 2025 | Twelve members objected; Australia did not |
| Viet Nam | 31 December 2025 | 11 September 2026 | Austria, Czechia and Germany objected; Australia did not |
| Thailand | 30 June 2026 | 28 February 2027 | Not yet in force; recheck objections before use |
Two things stand out. Each in-force date is roughly eight months after accession, and objections can prevent bilateral operation with particular parties. Check the live HCCH status table for dates, competent authorities and objection notices.
What does an objection mean?
When a contracting state objects during the Article 12 period, the Convention does not enter into force between it and the acceding state. That does not prescribe one universal replacement chain: the issuing and receiving authorities determine whether authentication, foreign-post legalisation or another process applies. Between the acceding state and non-objecting parties, the Convention operates from the stated date.
For an Australian document, inspect the accession entry and its objection notices for Australia. At the 9 October 2026 check, Australia was not listed among the objectors to Pakistan, Bangladesh or Viet Nam. Treat that as dated information, not a permanent shortcut; use the live HCCH record before preparing a document.
Why do countries join?
Legalisation is slow and costly for everyone involved. A document may pass through a ministry at home, the foreign ministry, and then the embassy of every country that will receive it, each with its own requirements, queues and fees. The Apostille Convention replaces that chain with a single certificate from an authority in the issuing country, recognised by every other member that has not objected. For countries whose citizens study, work, trade and marry abroad in large numbers, joining removes a real burden, which is why accessions have continued steadily in recent years.
For covered documents, the Convention removes the diplomatic or consular legalisation requirement between parties in a Convention relationship. It does not prevent an embassy from offering unrelated services or a receiving authority from asking for translation, certified copies, registration or substantive supporting evidence.
Who issues apostilles in the new member?
Each member designates one or more competent authorities to issue apostilles on its public documents. Often this is the foreign ministry, but some countries designate courts, regional offices or other bodies, and some designate different authorities for different kinds of document. A new member announces its competent authorities when it accedes, and the HCCH publishes them.
For Australians receiving documents from a new member, this matters when checking that an apostille is genuine: it should come from one of that country's designated authorities. Many members also run online registers where an apostille can be verified by its number and date. In Australia, the competent authority is DFAT. Our guide to verifying an Australian apostille explains how that works here.
What if the country is not a member yet?
Until the in-force date, or where the Convention does not operate between the relevant states, follow the receiving authority's current authentication route. A private document or copy may require Australian notarisation before DFAT authentication. A foreign embassy or consulate step is common but not automatic; confirm the complete chain, eligibility, fees and appointments with the recipient and foreign post.
What changes for Australian documents?
From the in-force date, a covered Australian public document going to the new party can use a DFAT apostille instead of diplomatic or consular legalisation where Australia did not object and authentication is required. It may reduce steps and fees. The recipient still decides which document, copy, translation, recency and registration requirements apply.
The reverse applies to documents coming from the new member for use in Australia: an apostille from that country's competent authority replaces its embassy's legalisation, where an Australian body asks for authentication at all. Many Australian uses, such as most visa applications, rely on translations and copies rather than apostilles anyway. Our apostille and authentication service guide explains the Australian certificate options, while our guide to foreign-document apostilles explains which country must issue the certificate.
What about documents prepared around the change date?
The change date creates awkward cases. Do not assume an authentication and consular legalisation completed under the previous route remains acceptable indefinitely; acceptance, document age and transaction rules belong to the receiving authority. Likewise, an apostille issued before the bilateral Convention relationship begins does not gain the required effect merely because the document is presented later.
If timing is close, ask whether to finish the existing route or wait and use an apostille after the effective date. Check the HCCH record, DFAT eligibility guidance and the foreign post's current notice, then retain the recipient's written answer. Our guide to choosing the right certificate type covers mistakes.
How do you prepare a document for a newly joined country?
- Check the HCCH status table for the country's in-force date and any objections involving Australia.
- Confirm with the receiving office that it now accepts apostilles, especially in the first months.
- Confirm document eligibility and arrange notarisation first only where required.
- Request the certificate specified after confirming the bilateral Convention relationship is in force.
- Arrange translation in the required sequence; it is not universally performed after the apostille.
What does this look like in practice?
Here is an illustration, not a real case. Hana needs a power of attorney for a property matter in Viet Nam in August 2026. She reads that Viet Nam has joined the Apostille Convention and asks DFAT for an apostille.
She then checks the HCCH status table and sees that the Convention only comes into force for Viet Nam on 11 September 2026. Because her lawyer needs the document before then, she follows the old route: notary, DFAT authentication and legalisation at the Vietnamese embassy. A friend with a similar document in October uses a DFAT apostille instead, after confirming the Vietnamese office will accept it.
What costs change after accession?
Where the Convention applies, an apostille can remove a foreign embassy or consulate legalisation step and its fee. It does not remove every cost. An Australian notary public, DFAT, translation, certified copies, foreign registration, courier and urgent-service charges may still apply depending on the document and recipient.
For a document near the transition date, compare itemised routes rather than headline certificate fees. Include the effective date, any objection involving Australia, document eligibility, appointments, processing time and expiry or recency rules. Paying for the older route early may be sensible when a deadline precedes entry into force; waiting may be simpler when the recipient confirms an apostille will be accepted.
In short
Accession becomes operational only on the stated entry-into-force date and only between the new party and non-objecting parties. For covered Australian public documents, a DFAT apostille then replaces diplomatic or consular legalisation where authentication is required. Check the live HCCH record and recipient instructions before choosing the route.

Frequently asked questions
When does the Apostille Convention start applying to a new member?
Not on the accession date. Under Article 12, it enters into force on the 60th day after the end of the six-month objection period. Check the HCCH status table for the exact date and bilateral objection position.
What happens if a country objects to an accession?
The Convention does not enter into force between the objecting party and acceding state. Their authorities determine the replacement authentication route. From the effective date, the Convention operates between the new state and parties that did not object.
Did Australia object to recent accessions?
At our 9 October 2026 check, Australia was not listed among the objectors to Pakistan, Bangladesh or Viet Nam. This is dated information. Inspect the accession entry and objection notices on the live HCCH status table before preparing a document.
Do I need to redo documents legalised before a country joined?
Do not assume either result. The receiving authority decides whether the earlier authentication and legalisation remain acceptable and whether document-age or transaction rules require a new document. Obtain its answer before redoing or relying on the old package.
My document is due just before the change date. What should I do?
Ask the receiving authority whether to complete the current authentication route or wait until the bilateral Convention relationship is in force. Check DFAT eligibility and the foreign post's notices, and keep the written answer.
Does joining the Convention remove the need for a notary?
No. It replaces diplomatic or consular legalisation for covered public documents; it does not turn a private document or copy into an eligible public document. Prior notarisation may still be required, depending on the document and DFAT rules.
Does an apostille replace translation?
No. An apostille does not translate the document or certify its contents. The receiving authority decides what must be translated, who may translate it and whether the apostille must be included in the translation.
Is Thailand a member of the Apostille Convention?
Thailand acceded on 30 June 2026, with entry into force shown as 28 February 2027 on the HCCH table checked 9 October 2026. The bilateral position is not operational before then, and objection notices should be rechecked before use.
Why do some offices still ask for legalisation after a country joins?
The effective date may not have arrived, an objection may prevent bilateral operation, the document may fall outside the Convention, or the request may concern translation or registration rather than legalisation. Ask for the legal basis and check the HCCH record.
Where can I check a country's Apostille Convention status?
The HCCH status table lists every party, its accession and in-force dates, and any objections. It is the authoritative source, and membership changes, so check it on the day you prepare your document.
