Legal documents in Thailand: drafting, certification and bilingual use
Bilingual contracts, powers of attorney and declarations need a clear governing-language clause, consistent defined terms, and signatures certified in the way the receiving party expects. Prepare identification for every signer, corporate authority documents where a company is a party, and the recipient's format requirements. Preparation is commonly about 3–10 working days.
Approximate total time: approximately 3–10 working days
Documents to prepare
Draft or instruction sheet always required
States the parties, obligations and the outcome you need.
Identification of every signer always required

Step-by-step process
1. Confirm purpose and governing language
Decide which language prevails if the two versions differ.
Duration: about 1 working day
2. Draft and align defined terms
Both language versions must use the same defined terms throughout.
Duration: about 2–5 working days
3. Review with all parties
Circulate one controlled version to prevent conflicting edits.
Duration: about 1–3 working days
4. Sign with the required certification
Notarisation is arranged where the recipient asks for it.
Duration: about 1 working day
5. Legalise for overseas use
Apostille or embassy legalisation as the recipient specifies.
Duration: about 3–10 working days
An adviser, not just a filing agency
Our team has worked on Thai document, translation, legalisation and visa cases for more than 15 years. Before we file anything we review your documents, tell you which route the receiving authority actually accepts, and flag the parts that commonly fail — so you are advised, not just served.
Prefer not to deal with the paperwork? We can run the whole case
- If you do not want two language versions drifting apart, we control the defined terms in both from the first draft.
- Signing, notarisation and legalisation are scheduled as one sequence rather than separate appointments.
- We confirm the recipient's certification format before signature, which avoids re-signing later.
Send the details of your case first. We will confirm the exact document list and the realistic timeline before any work starts.
Requirements are based on published rules of the relevant authorities and can change. Always confirm with the receiving party before filing.
