Apostille for Thai Documents

Thailand deposited its instrument of accession to the Hague Apostille Convention, and the Convention enters into force for Thailand on 28 February 2027. Until that date Thai documents still travel through the consular legalisation chain — Department of Consular Affairs plus the destination embassy. Planning ahead matters: files needed before the entry-into-force date should be prepared on the current route.
Who needs this
- Applicants told by a foreign authority that they need an Apostille on a Thai document
- People planning submissions that fall near or after 28 February 2027
- Companies scheduling multi-country filings that will straddle the change
Documents to prepare
- Original Thai public documentCivil registry certificates, court records, company affidavits or notarised private documents
- Certified translation where the destination requires itSpelling matched to the passport used at the destination
- Passport or ID of the holderUsed to verify identity and name transliteration
- Written statement of the destination requirementAn email or checklist from the receiving authority avoids preparing the wrong route
Step-by-step process
- 1. Confirm the deadline against the entry-into-force dateIf the document is needed before 28 February 2027, prepare it through consular legalisation instead of waiting for the Apostille route.Handled by: Applicant + our team · Typical time: Same day
- 2. Obtain or re-issue the source documentA recent original from the issuing agency avoids validity-window rejections.Handled by: Our team · Typical time: 1–3 business days
- 3. Translate and certifyCertified translation prepared to the destination's conventions where required.Handled by: Translator · Typical time: 1–2 business days

Overall timing
On the current consular route, a complete Thai document typically takes 3–7 business days before any embassy stage. Embassy queues are set by each mission and can add days or weeks.
Advice from our team
- Ask the receiving authority whether they will accept consular legalisation in the interim — many do
- Do not pay third parties who claim they can issue a Thai Apostille before the Convention is in force
- Keep high-resolution scans of every legalised page for online lodgements
Things to watch out for
- No Thai authority can issue an Apostille before the Convention takes effect for Thailand
- Apostille will apply only to public documents; private documents must be notarised first
- Even after entry into force, some authorities keep their own translation requirements
Frequently asked questions
When can Thailand issue Apostilles?
From 28 February 2027, the date the Hague Apostille Convention enters into force for Thailand.
What should I do before then?
Use the consular legalisation chain: Department of Consular Affairs authentication, then the destination embassy where required.
Will documents legalised now still be valid afterwards?
Documents already legalised remain valid as issued, subject to the receiving authority's own validity window.
Does an Apostille remove the need for translation?
No. Translation requirements are set by the receiving authority and are separate from authentication.
