The Hague Apostille Convention includes 129 signatory countries as of 2026, including recent additions Bangladesh, Vietnam, and Algeria. Apostille certification simplifies document authentication across all signatories without further legalisation. For non-signatory countries, traditional diplomatic legalisation is required – a more complex, time-consuming process. NotaryPublic24 provides guidance and authentication services for both Hague Convention and non-signatory jurisdictions.
Introduction
The Hague Apostille Convention is one of the most important international legal agreements affecting document authentication worldwide. If you’re sending documents across borders – whether for property transactions, business registrations, educational submissions, or legal proceedings – understanding which countries are signatories to the Hague Convention determines whether your documents need Apostille certification.
As of 2026, 129 countries and territories are parties to the Hague Convention. This includes major global economies, Commonwealth nations, EU member states, and growing participation from Africa, Asia, and the Middle East. Yet several significant markets remain non-signatories, requiring alternative diplomatic legalisation procedures. This comprehensive guide lists all 129 Hague Convention countries, highlights recent additions, identifies notable non-members, and explains what to do when documents must reach non-signatory jurisdictions.
What Is the Hague Convention (Apostille Convention)?
The Hague Convention of 1961 (formally ‘Convention Abolishing the Requirement of Legalisation for Foreign Public Documents’) is an international treaty that simplifies document authentication across participating countries. It introduces the Apostille – a single-step certification that validates a document’s authenticity without requiring consular verification.
Before the Hague Convention, authenticating documents for international use was complex and time-consuming. You needed to submit documents through official diplomatic channels for legalisation – a process involving your country’s embassy or consulate and the receiving country’s government. This could take weeks or months.
The Apostille streamlined this process. When a Notary Public, government agency, or court in one Hague Convention country applies an Apostille certificate to a document, all other signatory countries automatically recognize its authenticity without further verification.
The key principles:
- Apostille certificates are recognized by all 129 Hague Convention signatories
- No further legalisation is required once Apostille is applied
- Apostille is valid indefinitely (documents don’t need re-certification)
- The process is significantly faster than traditional diplomatic legalisation
Today, the Hague Convention is the default standard for international document authentication. Understanding which countries are signatories is essential for anyone sending documents across borders.
Recent Additions to the Hague Convention
The Hague Convention is actively growing. Recent signatories significantly expand geographic coverage and include major emerging markets:
Recent Additions (2025–2026):
- Bangladesh (2025): Significant addition for education and business documentation from South Asia
- Algeria (2026): Expands coverage in North Africa; major implications for business and property documents
- Vietnam (2026): Critical addition for growing business ties in Southeast Asia
These recent additions are important – if you’re working with partners in Bangladesh, Algeria, or Vietnam, Apostille certification is now available and recognized. This eliminates the need for expensive and time-consuming diplomatic legalisation.
The continued expansion of the Hague Convention reflects its utility and international recognition. As more countries join (negotiations continue with several others), document authentication becomes simpler and faster globally.

Total: 33 countries. Note: UAE is listed as a partial signatory for notarized documents only (not for consular documents). Recent additions of Bangladesh and Vietnam significantly improve coverage for South and Southeast Asian business and education documents.
Africa
African signatories are growing, with significant recent addition of Algeria in 2026. Current participants include:
Algeria, Benin, Botswana, Burkina Faso, Cameroon, Cape Verde, Côte d’Ivoire, Egypt, Gabon, Gambia, Ghana, Guinea, Guinea-Bissau, Kenya, Lesotho, Liberia, Libya, Madagascar, Malawi, Mali, Mauritius, Morocco, Mozambique, Namibia, Niger, Nigeria, Rwanda, Senegal, Seychelles, Sierra Leone, South Africa, South Sudan, Swaziland (Eswatini), Togo, Tunisia, Uganda, Zambia, Zimbabwe
Total: 37 countries. Algeria’s 2026 accession is significant for North African transactions. Sub-Saharan African coverage remains strong, though some smaller nations remain non-signatories.
Middle East (listed separately from Asia–Pacific above)
Middle Eastern signatories include major economies and trade partners:
Bahrain, Oman, Qatar, Saudi Arabia (listed above in Asia–Pacific section), United Arab Emirates (listed above – partial signatory for notarized documents).
Additional Middle East coverage through pan-regional signatories is growing, though some major markets (Iran, Iraq, Syria, Yemen) remain non-signatories.
Notable Non-Signatory Countries
While 129 countries are signatories, several significant markets remain outside the Hague Convention. Understanding these is critical for international document planning.
Major non-signatories include:
- United Arab Emirates (UAE) – Partial signatory for notarized documents only. For consular documents, traditional legalisation may be required
- Iran – Does not recognize Apostille; requires embassy legalisation
- Iraq – Limited participation; diplomatic legalisation typically required
- Syria – Not a signatory; requires embassy legalisation
- Yemen – Not a signatory; requires diplomatic legalisation
- North Korea – Not a signatory
- Palestine – Not formally a signatory (special status)
- Some Gulf states and Central Asian countries remain non-signatories
- Several microstates and smaller nations are not signatories
If your documents must be used in non-Hague Convention countries, you’ll need to pursue traditional diplomatic legalisation instead – a more complex and time-consuming process involving your country’s Foreign Office and the receiving country’s embassy.
What to Do If Your Destination Country Isn’t a Hague Convention Signatory
If you need documents authenticated for use in a non-signatory country, Apostille is not sufficient. You must pursue traditional diplomatic legalisation.
The diplomatic legalisation process:
- Have your document notarized by a UK Notary Public
- Submit the notarized document to the UK Foreign, Commonwealth & Development Office (FCDO) for verification
- The FCDO forwards the document to the relevant country’s embassy in London for legalisation
- The embassy applies their legalisation stamp, confirming the UK notary’s authority
- The document is returned to you – now valid in the non-signatory country
This process typically takes 4–8 weeks and involves coordination between multiple government agencies. It’s significantly more time-consuming and expensive than Apostille certification.
For non-signatory countries, plan ahead. Don’t wait until deadlines are imminent – diplomatic legalisation requires time.
If you’re unsure whether your destination country is a Hague Convention signatory, contact NP24 during your notarization consultation. We’ll confirm the exact authentication process required.
Apostille Certification – How It Works for Hague Convention Countries
For Hague Convention signatories, Apostille certification is the standard authentication method. Here’s how it works:
- You have a document notarized or verified by a UK Notary Public, court, or government agency
- An Apostille certificate is attached to or incorporated into the document
- The Apostille contains the UK notary’s signature, seal, and certification number
- All 129 Hague Convention countries automatically recognize the Apostille’s validity
- No further legalisation or embassy involvement is needed
Key Apostille facts:
- Issued instantly or within 24 hours (no lengthy processing)
- Valid indefinitely – documents don’t need re-certification
- Prevents the need for further verification across all signatory countries
- More affordable than diplomatic legalisation
- Can be attached to original or certified copy documents
Many international transactions benefit from combined notarization and Apostille service – submit once, receive both authentication layers within 24 hours. This is particularly valuable for property transactions, business registrations, and educational submissions across Hague Convention countries.
Examples of Document Types Requiring Apostille
Common documents requiring Apostille for international use:
- Birth, marriage, and death certificates: Required for immigration, citizenship applications, and property transactions
- Educational credentials and diplomas: Needed for university applications, professional registration, and work visas
- Power of Attorney documents: Essential for managing international affairs or property
- Certified copies of identity documents: Required for business registration, banking, visa applications
- Company documents and corporate certificates: Used for international business transactions and registrations
- Court documents and judgements: Needed for enforcing legal decisions across borders
- Affidavits and declarations: Required for international legal proceedings
- Bank statements and financial documents: Often needed for immigration and property transactions
For any UK document being used internationally, check whether your destination country is a Hague Convention signatory. If yes, Apostille is your solution. If no, pursue diplomatic legalisation.
Checking If Your Destination Country Is a Hague Convention Signatory
To verify whether a specific country is a Hague Convention signatory:
- Refer to the country lists in this article (organized by region)
- Visit the official Hague Conference of International Private Law website (though most providers don’t maintain perfect, current lists)
- Contact NP24 and ask directly – we can confirm signatory status and advise on the correct authentication process
- Check with the destination country’s UK embassy or consulate
- Consult the organization requesting your documents – they can confirm whether Apostille or legalisation is required
This verification is important. Sending documents authenticated with Apostille to a non-signatory country wastes time and money – the Apostille won’t be recognized, and you’ll need to restart the process with diplomatic legalisation.
If you’re planning international document authentication and uncertain about your destination country’s status, verify before committing to a specific authentication path.
Future Growth of the Hague Convention
The Hague Convention continues to expand. Several additional countries are in negotiations for membership, which would bring coverage closer to universal participation.
Potential future signatories include countries in Central Asia, additional Middle Eastern states, and some African nations currently undergoing the accession process.
The trend is clearly toward broader Hague Convention participation. This is positive for international document users – more countries participating means simpler, faster, cheaper authentication for a growing proportion of global transactions.
However, some nations may remain outside the Convention for political or administrative reasons. For long-term international planning, building relationships with professional notarization providers familiar with both Hague Convention and non-signatory legalisation processes is valuable.

Can I use an Apostille certificate in any country in the world?
No. Apostille is recognized only in Hague Convention signatory countries (129 as of 2026). For non-signatory countries, you must pursue traditional diplomatic legalisation. Always verify your destination country’s signatory status before choosing authentication method.
If my destination country just joined the Hague Convention, can I use my old legalised documents?
Documents previously legalised through diplomatic channels remain valid. However, for future document authentication in newly-acceded countries like Bangladesh, Vietnam, or Algeria (2026), Apostille is now the simpler and faster option.
