Certified vs. Notarized: Which Do You Need?
Different offices ask for different certification levels. The right choice depends on where the tax document will be submitted.
Certified Translation
Standard certification includes a translator statement, company seal, and signature. This is enough for many routine submissions.
- Thai Immigration visa extensions
- Work permit applications
- Bank account and loan applications
- Embassy visa applications
- Internal corporate compliance
Cost: Translation price only
Notarized or MFA Legalized Translation
Some files need certified translation with Ministry of Foreign Affairs authentication, especially for court, overseas, or embassy-specific use. Others need attorney notarization instead — the two are separate paths, and the MFA does not legalize notarized documents.
- Court proceedings and litigation
- Cross-border regulatory submissions
- Some embassy-specific requirements
- International tax authority submissions
- Overseas government filings
Cost: Translation + MFA fees, or translation + notarization
