English service · Apostille · HCCH effective 28 February 2027
Since 28 February 2027 Thai-issued public documents can be Apostilled by the MFA Consular Department — replacing the older embassy chain for any Hague country. We handle notarisation of private documents, certified translation and MFA filing under one fixed-fee engagement.
On 28 February 2027 the Hague Apostille Convention entered into force for Thailand, making it the 126th party. Thai-issued public documents going to any of the other 130 contracting states can now be certified with a single Apostille issued by the Department of Consular Affairs at the Ministry of Foreign Affairs — replacing the older chain of MFA legalisation + destination embassy legalisation.
Thai Notary Law was among the first Thai law firms to file Apostille requests under the new regime. This page is the long-form English reference: which documents qualify as 'public documents', how the MFA actually issues the Apostille, how to handle private documents (notarisation first), realistic timelines and fees, and the situations where embassy legalisation is still the right choice.
The Apostille Convention abolishes the requirement of legalisation between contracting states for foreign public documents. A single certificate — the Apostille — issued by the Competent Authority of the country of origin replaces the older chain of consular legalisations. For documents originating in Thailand, the Competent Authority is the Department of Consular Affairs of the Ministry of Foreign Affairs.
Article 1 of the Convention defines 'public documents' as: court documents, administrative documents, notarial acts, and official certificates placed on documents signed by persons in their private capacity (such as official certificates recording the registration of a document). Private documents — commercial contracts, statutory declarations, corporate resolutions of private companies — are not directly apostillable, but become eligible once notarised by a Notarial Services Attorney, because the notarisation itself is a notarial act.
Most public documents now require only two steps in Thailand instead of three or four. The simplification is meaningful — most engagements that previously took 2 to 4 weeks now complete in 5 to 10 working days, and the receiving authority abroad accepts the document without further legalisation.
Even though the Apostille is faster than the old chain, the document still has to be assembled correctly. We do the assembly, the translation and the MFA filing as a single engagement.
Most Apostille engagements run 3 to 7 working days for express, or 7 to 10 working days for standard, including notarisation and translation. The bottleneck is usually the original document — getting a re-issued school transcript or birth certificate from a provincial registry typically takes more time than the Apostille itself.
Below is a working list of high-volume destinations where, from 28 February 2027, the Apostille fully replaces embassy legalisation. The list is not exhaustive — the full status table is maintained by HCCH and we confirm the current state at intake.
Apostille is the new default, but not the answer in every case. Non-Hague destinations (Vietnam, mainland China for most document types pending bilateral, Iran, Egypt, Pakistan, Sri Lanka) still require embassy legalisation. Within Hague countries, a small number of receiving institutions — typically immigration files and certain commercial customs counterparties — continue to insist on embassy stamps despite the Apostille's legal sufficiency.
We provide a written Apostille-vs-embassy recommendation at intake. Where the client wants insurance against a stubborn receiving authority, we can run both chains in parallel for a moderate fee increase.
The MFA Apostille fee itself is quote on request (phone / LINE / email) standard or quoted on request express per document. Our professional fee covers pre-screening, notarisation (where needed), translation, MFA filing and binder assembly. International courier is at cost.
The Convention entered into force for Thailand on 28 February 2027. The MFA Department of Consular Affairs began accepting Apostille applications from that date at the Chaeng Watthana office.
MFA is rolling out e-Apostille for certain document types in phases. Most receiving authorities outside Thailand are not yet equipped to verify Thai e-Apostilles; we default to paper Apostille and switch to e-Apostille only when the receiving authority confirms acceptance.
No. The Apostille is issued by the country of origin of the document. A US-issued degree must be Apostilled in the US; a Thai-issued degree is Apostilled in Thailand. We coordinate with foreign Apostille services for our cross-border clients.
No, the Apostille itself has no expiry. The underlying document may have practical expiry — a Single Status certificate is typically accepted only if issued in the last 6 months — but the Apostille on it remains valid indefinitely.
Yes — the standard practice is to bind the certified translation behind the original document and have the MFA Apostille the bound packet. Some Spanish, Italian and Greek universities require the translation to be Apostilled separately; we file accordingly when intake confirms it.
Yes. Court orders are public documents and qualify directly. We collect the certified copy from the court registrar, then file the Apostille without the notarisation step.
Send us a scan of your Thai document and tell us the destination country and authority. We will return a written Apostille-vs-embassy recommendation, a step-by-step plan and a fixed-fee quote within one business day.
Send a photo of your document over LINE — we reply with a fixed price within one business day.
Short answer: An Apostille is a single-layer certificate used between parties to the Hague Convention. For Thailand the Convention enters into force on 28 February 2027. Until then Thai documents still follow chain legalization through the Department of Consular Affairs and the destination embassy.

Document and legalization advisers with 15+ years of practice
Before we start, we read your actual documents and confirm the legalization route matches what the receiving authority asks for. During the work we report progress, and after delivery we still answer questions about how to submit the file.
We prepare documents to the requirements of the receiving authority. Any approval decision remains at that authority's discretion.
Send your documents on LINE for a preliminary review, a recommended legalization route and a written quote.
General guidance, not a case-specific determination. Requirements change with agency notices — confirm with the receiving authority before you act.

Short answer: Most refusals involve documents that are not yet public documents under the Convention, destinations that are not contracting parties, and confusion about Thailand's entry into force on 28 February 2027. Fix it by upgrading the document first, then matching the route to the destination's status.
We confirm whether your document qualifies, whether the destination is a contracting party, and which route is safest during the transition — ask us before you spend a cycle finding out.
