Apostille vs Consular Legalisation for Thai Documents
Thailand deposited its instrument of accession to the Hague Apostille Convention, with entry into force on 28 February 2027. Until then every outbound document still needs the full legalisation chain, so timing matters for anyone planning a move.
In short
Today, Thai documents used abroad need Department of Consular Affairs legalisation followed by the destination embassy. From 28 February 2027, documents going to another Convention country need only an apostille from the Thai competent authority, removing the embassy step. Documents for non-Convention countries keep the current route.
Side-by-side comparison
| Criterion | Apostille (from 28 Feb 2027) | Consular legalisation (current route) |
|---|---|---|
| Available now | No, from 28 February 2027 | Yes |
| Steps involved | Translate, then a single apostille certificate | Translate, MFA legalisation, then embassy stamp |
| Countries covered | Hague Convention members only | Any country, including non-members |
| Government fee | Set by the competent authority, published closer to the date | 200 THB per document at MFA, 400 THB express, plus embassy fees |
| Typical duration | Expected to be shorter, one authority only | 7-21 working days across two authorities |
| Validity of documents issued before 2027 | Can be apostilled later if still current | Stays valid, no need to redo |
| Translation still required | Yes, if the receiving office does not read Thai | Yes |
| Best planning advice | If filing after Feb 2027, wait rather than pre-legalise | If filing before, start now, embassy queues are the bottleneck |
Choose Apostille (from 28 Feb 2027) when
- Your filing date falls after 28 February 2027 and the destination is a Convention member
- You want to avoid embassy appointment queues in Bangkok
- The receiving authority explicitly asks for an apostille
Choose Consular legalisation (current route) when
- You need the document before 28 February 2027
- The destination country is not a Convention member
- The receiving office insists on its own embassy stamp regardless of the Convention
Frequently asked questions
- Will documents legalised before 2027 be rejected afterwards?
- No. Legalisation already completed remains valid. The change affects how new documents are certified, not documents already stamped.
- Does an apostille remove the need for translation?
- No. An apostille authenticates a signature and seal. If the receiving office works in another language, you still need a translation prepared to its standard.
- Which documents can be apostilled?
- Public documents such as civil registry records, court papers, police clearance certificates and notarised instruments. Private documents usually need notarisation first.
- How should I plan a 2026 application?
- Tell us your filing month. If it is before the effective date we prepare legalisation now; if it is after, we schedule the file so nothing is paid twice.
