Documents required
- •Original document with signature and issuing-authority seal
- •English translation (for use in Apostille countries)
- •Form KT.02-A (Apostille-specific form, not the generic KT.02)
Common pitfalls
- ⚠Apostille only works for Convention members — mainland China, Cambodia, UAE do not accept it
- ⚠KT.02 vs KT.02-A are different forms — filing on the wrong one voids the case
- ⚠A document already Apostilled cannot then be embassy-legalised — pick the track upfront
NYC insider tips
- 💡Translations for Apostilled documents are best done in the destination country's language — many embassies re-translate anyway
- 💡126 Hague members as of 2026: EU-27, UK, US, Australia, Japan, Korea (partial), Singapore, Hong Kong
- 💡NYC has a dedicated Apostille officer on-site daily — book the fast-track internally
FAQ
Apostille vs traditional legalisation — what's the difference?
Apostille = one seal, ready to use. Traditional = MFA seal + destination-embassy seal (two seals).
Is it cheaper?
Much cheaper — saves THB 800–4,500 per embassy fee plus 3–15 days of waiting.
Do older embassy-legalised documents still work?
Yes, but for new filings prefer Apostille — faster and cheaper.
