Use qualified review for consequential property documents.
Which documents need careful review?
- sale and lease agreements;
- title records;
- powers of attorney;
- tax receipts;
- formal notices.
A power of attorney and the underlying title deed (chanote) are two of the highest-stakes documents to get translated correctly; when a translated term is disputed, hiring a Thai lawyer for review is worth the cost.
What does an official certified translation actually cost and take?
The Legalization Division of the Department of Consular Affairs, Ministry of Foreign Affairs, publishes a standard fee schedule for its own certified translations, signature certifications and true-copy certifications:
- general documents (identity, household registration, family registration, corporate registration): THB 200 per copy for regular service, about 2 business days not counting the day you submit, or THB 400 for urgent (same- or next-day) service;
- contracts or legal documents: THB 200 for the first 100 words or fewer, then THB 200 for every further 100 words or part of 100 words, so a multi-page lease or sale agreement is priced by length, not as a flat fee;
- certified signatures and certified true copies of government-issued documents follow the same THB 200 / THB 400 regular-versus-urgent structure.
These are the Ministry's own fees for its own certification step, not what a private translation agency charges for the translation itself, budget for both where a document needs full legalization rather than only a translation.
Can an apostille replace this process yet?
Not yet, and this is a live change worth tracking if you are translating documents for a cross-border transaction. Thailand deposited its instrument of accession to the 1961 Hague Apostille Convention on 30 June 2026. Accession carries an objection period of roughly six months for the Convention's existing member states, running to on or around 30 December 2026, and the Convention only enters into force for Thailand 60 days after that, on 28 February 2027. Until it takes effect, Thailand's existing chain-legalization process is unchanged: a foreign document for use in Thailand, or a Thai document for use abroad, still needs to go through the issuing authority, then (for a foreign document) the relevant embassy or Thailand's Ministry of Foreign Affairs, in sequence, rather than a single apostille stamp. Re-check this page's Sources before relying on it if you are reading this after February 2027.

Is an app translation enough for a contract?
No. Use qualified human review for consequential documents.
Should names and numbers be checked separately?
Yes. Verify legal names, dates, amounts and property identifiers line by line.
When is certification needed?
Confirm the receiving authority's current requirements.
What does an official certified translation through the Ministry of Foreign Affairs cost?
The Legalization Division of the Department of Consular Affairs charges a standard fee per copy for its own certified translations and certifications: THB 200 for regular service (about 2 business days, not counting the submission date) or THB 400 for urgent service, for most general documents. A contract or legal document is charged per 100 words rather than as a flat fee, so a long lease or sale agreement costs more than a short certificate.
Can apostilles be used for Thai property documents yet?
Not yet. Thailand deposited its instrument of accession to the 1961 Apostille Convention on 30 June 2026, but accession carries roughly a six-month objection period for existing member states, and the Convention does not enter into force for Thailand until 28 February 2027. Until that date, the existing chain-legalization process through the embassy or consulate and the Department of Consular Affairs still applies, do not request or accept an apostille for a Thai document, or expect Thailand to accept one on a foreign document, before then.
Who can translate a power of attorney or title deed for use at the Land Office?
There is no single government list of licensed translators for most documents. What the Land Office and other Thai authorities actually require is that the content is accurate and, where the document will be used with a foreign authority or embassy, that it carries the right chain of certification, the translator's or notary's certification, then consular legalization where required. For a power of attorney signed abroad for use in a Thai property transaction, check the specific requirements of the embassy or consulate issuing it and the Thai authority receiving it, since practice differs by country.
What should you bring to the Legalization Division in person?
The original Thai document plus one copy, the translated document, and a certified copy of your ID, if someone else is submitting on your behalf, a power of attorney naming them, with both your and their ID copies attached. Requirements vary slightly by document category, so check the current list on the Department of Consular Affairs site before the visit.
