Apostille Thailand — Hague Convention
Entering into force for Thailand on 28 February 2027 — it will replace the MFA + embassy chain for the 130 Contracting Parties.
Quick Answer
Apostille is a single-step authentication issued by the Department of Consular Affairs, MFA Thailand. It becomes available for Thai documents on 28 February 2027. Today your document still needs MFA legalisation plus the destination embassy — we handle that chain now and switch you to the Apostille route automatically once it opens.
Documents we prepare for Apostille
- ✓ Birth / marriage / death certificate
- ✓ Divorce decree
- ✓ Academic transcript / diploma
- ✓ Police clearance certificate
- ✓ Corporate DBD extract / MoA
- ✓ Power of Attorney
- ✓ Board resolution
- ✓ Court judgment
- ✓ Medical / vaccination record
- ✓ Notarial deed
FAQ
- Is Apostille available in Thailand yet?
- Not yet. Thailand deposited its instrument of accession on 30 June 2026 and the Convention is scheduled to enter into force for Thailand on 28 February 2027. Until that date every Thai document still needs MFA (Department of Consular Affairs) legalisation plus destination-embassy legalisation. We prepare files now so they can switch to the Apostille route the day it opens.
- Which authority will issue Apostille in Thailand?
- The Legalization Division of the Department of Consular Affairs, Ministry of Foreign Affairs (Chaeng Wattana) — the same office that handles legalisation today. We submit on your behalf; you do not need to visit MFA in person.
- Turnaround?
- Current MFA legalisation: normal 3 working days, express same-day where the queue allows. Destination-embassy steps add 5–15 working days depending on the mission.
- What changes for me on 28 February 2027?
- For the 130 Contracting Parties, the destination-embassy step disappears — one Apostille certificate from MFA is enough. Non-member destinations (e.g. mainland China for some document types, several Gulf states) keep the two-step chain. Always confirm with the receiving authority before filing.

Where Thailand stands on the Apostille Convention right now
Thailand deposited its instrument of accession to the HCCH Convention of 5 October 1961 Abolishing the Requirement of Legalisation for Foreign Public Documents. The Convention enters into force for Thailand on 28 February 2027. Until that date, no Thai authority issues an apostille certificate, and any provider offering a Thai apostille today is describing something that does not yet exist. Plan on the current chain and treat the 2027 date as a change to prepare for, not a service to buy now (source: hcch.net status table; consular.mfa.go.th announcements).
The practical consequence is directional. Documents leaving Thailand still pass through the Department of Consular Affairs, Ministry of Foreign Affairs, and then, for non-member destinations, through the destination embassy in Bangkok. Documents arriving in Thailand from a country that is already a member are a different matter: an apostille issued abroad is only meaningful in Thailand once Thailand is itself bound, so inbound papers today still need Thai embassy or consulate endorsement in the country of origin before the MFA will certify a Thai translation.
Inbound versus outbound, decided before anything is signed
| Direction | Chain that applies before 28 Feb 2027 | What changes after |
|---|---|---|
| Thai document used abroad (member state) | Translation → MFA legalisation → destination embassy in Bangkok | MFA apostille replaces the embassy step for member states |
| Thai document used abroad (non-member) | Translation → MFA legalisation → destination embassy | Unchanged; the embassy step stays |
| Foreign document used in Thailand (member state) | Origin-country certification → Royal Thai Embassy there → Thai translation → MFA | Foreign apostille accepted; Thai embassy step falls away |
| Foreign document used in Thailand (non-member) | Origin certification → Royal Thai Embassy → Thai translation → MFA | Unchanged |
How we prepare clients for the transition
- Date the requirement, not the document: What matters is when the receiving authority will assess the file, not when you commission the work. Files landing before the entry-into-force date follow the current chain even if the document is issued later.
- Avoid stockpiling: Many receiving authorities treat civil-status certifications as fresh only for three to six months. Certifying early to beat a future rule change usually wastes the certification.
- Check the receiving body's own rule: Convention membership sets the ceiling, not the floor. Universities, land registries and pension funds frequently keep their own translation and certification requirements on top.
- Keep the source certified copy current: Register offices reissue civil-status extracts cheaply; a fresh extract avoids arguments about a faded seal far more reliably than a re-scan.
Documents most affected by the switch
- Birth, marriage and death certificates for family and spousal applications in EU member states
- Degree certificates and transcripts for study and professional recognition
- Police clearance certificates, where validity windows are short and the embassy step is the slowest link
- Company affidavits and powers of attorney for cross-border transactions, where signature authority is checked closely
- Court judgments and divorce registrations used for remarriage abroad
Common mistakes and how we avoid them
More questions we are asked
- Can I get an apostille on a Thai document today?
- No. Thailand is bound by the Convention from 28 February 2027. Before that date the MFA issues legalisation certificates, not apostilles.
- Will the MFA step disappear in 2027?
- No. The MFA becomes the competent authority issuing the apostille, so documents still pass through it; what usually falls away is the destination-embassy visit.
- Does an apostille prove the content is true?
- No. It certifies the origin of the signature, the capacity of the signatory and the identity of the seal only.
- My foreign document already carries an apostille — is that enough for a Thai office?
- Not before entry into force. Thai receiving offices currently look for Royal Thai Embassy endorsement, then a Thai translation certified by the MFA.
- Should I wait until 2027?
- Only if the deadline genuinely allows it. Certification validity windows and visa lodgement dates almost always argue for proceeding under the present chain.
- How long does the current outbound chain take?
- Typically two to four weeks end to end, depending on the destination embassy's queue; MFA turnaround is the shorter part of it.

Frequently asked questions
- When does Thailand start issuing Apostilles?
- Thailand acceded to the Hague Apostille Convention and the Convention enters into force for Thailand on 28 February 2027, after which a single apostille certificate from the Department of Consular Affairs will replace the embassy legalization step for documents used in other member states. Until that date the existing two-step MFA plus embassy chain continues to apply.
- Should I wait for the Apostille system before sending documents abroad?
- Only if your deadline genuinely falls after February 2027. Documents legalized under the current chain remain valid after the change, and waiting risks your source documents ageing past the destination's validity window. If your submission is in 2026, use the current MFA plus embassy route.
- Will the apostille work for every country?
- No — an apostille is only valid between Hague Convention member states, and documents for non-member countries such as several Middle Eastern and African destinations will still require the full embassy legalization chain. Some member states have also raised objections to specific accessions, so the destination should always be checked individually.
- How do I plan timelines for a large document set?
- Work backwards from the submission deadline: allow three working days for standard legalization or one for express, plus embassy processing which ranges from same-day to two weeks depending on the mission, plus courier time and, critically, the time needed to obtain fresh certified copies from Thai issuing offices. For sets over about twenty documents, submissions are usually split into batches so a single problem document does not hold the entire file.
