Thai Birth Certificate Translation & Legalization
How to translate and legalize a Thai birth certificate for use overseas — visa, citizenship, school enrollment.
Frequently asked questions
Which is the correct Thai birth certificate form?
Sor Thor 1 (original) or Sor Thor 2 (extract) — both are accepted; iLC translates either.
Can the embassy refuse it?
Only if the translation is uncertified — iLC certified translations are universally accepted.

Documents usually required
- Freshly issued original Thai civil or corporate record from the issuing office
- Complete English translation of every page, with the translator's statement of accuracy
- Copy of the document holder's passport or Thai national ID card
- Power of attorney with ID copies of both parties if someone else files on your behalf
Common reasons a bundle is rejected
- Countries outside the Apostille Convention still need a further endorsement at the destination embassy.
- Translations that use an unofficial English name for a Thai agency are sent back for correction.
- Spell every name exactly as it appears in the passport, across every document in the same bundle.

How the process runs — Legalization at the Department of Consular Affairs
- Obtain a freshly issued original from the office that produced the record and check that every page is present.
- Prepare a complete translation with the translator's statement of accuracy attached.
- File for legalization at the Department of Consular Affairs, Ministry of Foreign Affairs, with the original and the translation together.
- Complete the next certification layer required by the destination country — Apostille, or legalization at that country's embassy in Thailand.
- Collect the finished bundle, scan a full copy for your records, then submit it in the format the receiving authority specifies.
Fees and processing times are set by each authority and vary by document and destination — confirm them with the responsible agency.
Handling it yourself vs letting iLC run it
| Aspect | Doing it yourself | With iLC |
|---|---|---|
| Working out which steps apply | You read each authority's rules yourself, and usually learn a step was missing only after the bundle is refused. | Our advisers review the documents before work starts and sequence translation, notarisation, MFA, and embassy in one pass. |
| Time spent filing | Repeat trips to each office, queueing and collecting in person. | We file on your behalf; you send scans and receive the finished set by post or courier. |
| Risk that the translation is refused | Agency names, job titles, and the certification wording often do not match what the receiving office accepts. | We use terminology and certificate formats the receiving authority has accepted before, with two-stage proof-reading. |
| If the bundle is rejected | You diagnose the cause and refile yourself, losing a full cycle. | We identify the cause, correct it, and refile without you starting over, with progress reported along the way. |
