Legalising a Thai Affidavit for China
If you are relocating to, studying in, marrying in, or doing business with China, your Thai Affidavit will only be accepted once it carries both the Thai MFA legalization stamp and the China embassy authentication. We prepare the certified translation, secure the consular stamp in Chaeng Watthana, and submit the file to the China mission at ถนนรัชดาภิเษก on your behalf.
Why the legalization chain is required
Legalization is a chain of trust, not a formality. When a China officer sees the embassy stamp on your Affidavit, they are trusting the embassy, which trusted the Thai MFA, which trusted the issuing office. NYC Legal builds this chain in the correct order so the final China authority accepts the document without follow-up questions.
Certified translation requirements
Because the China embassy reads the translated text, translation accuracy directly determines acceptance. Names must match your passport exactly (including transliteration), dates must follow the destination format, and official Thai terminology must map to the correct China legal equivalent. We proofread against your passport and prior documents before submission.
Transparent, itemised pricing
Costs are itemised, never bundled opaquely. Expect the China consular fee (สอบถามเจ้าหน้าที่), the MFA legalization fee (THB 200–400 standard), translation (THB 800–1,500/page), and our handling fee (สอบถามเจ้าหน้าที่). We quote the exact total up front — including courier — so there are no counter-side surprises when your Affidavit reaches the China mission.
Realistic timelines you can plan around
Plan for 7-14 วัน at the China embassy stage, on top of 2–3 business days at the Thai MFA and 1–3 days for certified translation. Realistically a single Affidavit takes 7–21 business days end to end. If you have a visa interview or filing deadline, tell us first — express MFA and priority embassy handling can compress this materially where the mission allows it.
What a legalised Affidavit is used for
Foreign nationals typically need a legalised Affidavit when dealing with China government offices, courts, universities, employers or banks — anywhere the receiving party must trust a Thai record. At this mission the highest-volume documents are Authentication, Notarized Translation, 公证, and we handle each with the correct chain for its purpose.
Common mistakes we help you avoid
Common mistakes with a Affidavit for China: wrong order of stamps, an unverifiable translator, mismatched transliteration of names, missing supporting documents (e.g. a marriage certificate needed alongside a name-change record), and booking the embassy before the MFA step is complete. Our review catches these before they cost you a wasted counter visit.
Why work with NYC Legal
Doing this yourself means multiple trips across Bangkok, queueing at the MFA and the China mission, and risking a wasted day if any detail is off. We consolidate the entire Affidavit legalization into one managed service, submit at ถนนรัชดาภิเษก on your behalf, and return the document ready to file — in Thailand or shipped internationally.
