If you have recently moved to Pattaya or are planning to apply for a visa, work permit, or marriage registration, you have probably been told that your documents need a "certified translation." But what does that actually mean, and which documents require it?
This guide covers everything you need to know about certified translation in Thailand — what it is, which documents need it, and how to get it done quickly in Pattaya.
What Is a Certified Translation?
A certified translation is a translation of an official document accompanied by a signed declaration from a qualified translator confirming that the translation is accurate and complete. In Thailand, certified translations are required when submitting foreign-language documents to Thai government offices, embassies, and courts.
The translation must be completed by a professional translator. In many cases, it also needs to be notarised by a licensed Notarial Services Attorney — particularly for court submissions and certain embassy requirements.
Documents That Commonly Require Certified Translation
Passport and Identity Documents
Your passport biographical page is the most frequently translated document in Thailand. A certified Thai translation is required for:
- Long-term visa applications (Non-Immigrant O, B, ED)
- Work permit applications
- Marriage registration at the district office
- Property purchase and ownership transfers
Birth Certificates
A certified translation of your birth certificate is needed for:
- Marriage registration at the Amphoe (district office)
- Applying for a Thai child's birth certificate
- Inheritance and estate matters
Marriage and Divorce Certificates
If you have been previously married, you will need a certified Thai translation of your marriage certificate or divorce decree when registering a new marriage in Thailand or applying for a dependent visa.
Criminal Background Checks
A police clearance certificate from your home country — with a certified Thai translation — is required for Non-Immigrant B visa applications, teaching licence applications, and certain professional licences.
Academic Certificates and Transcripts
Certified translations of degrees and transcripts are needed for work permit applications (especially for teachers and professionals), university enrolment, and professional licence applications.
Business and Legal Documents
Foreign businesses operating in Thailand often need certified translations of articles of incorporation, shareholder agreements, board resolutions, and financial statements for BOI applications.
Does Every Translation Need Notarisation?
Not always. The level of certification required depends on the receiving authority:
- Thai government offices (immigration, district office): Usually require a certified translation with the translator's signature and stamp.
- Thai courts: Require notarisation by a Notarial Services Attorney.
- Foreign embassies in Thailand: Requirements vary by country — always check with the specific embassy.
How Long Does It Take?
Most standard certified translations are completed within 1–2 business days. Urgent same-day service is available for most document types.
