Three pricing tiers
IVC's Notarial Services Attorneys (Lawyers Council of Thailand) — from 500+ notarizations per month — answer directly: Thai notary fees follow a three-tier structure — (1) single documents at THB 500 per page for passport copies, bank statement certifications, or witnessing a simple signature; (2) standard sets at THB 800–1,000 per document for POAs, affidavits, and declarations with English translation; (3) corporate bundles at THB 3,500–8,000 flat covering board resolutions, certified copies of company documents, and signing-authority packages.
Hidden extras first-time clients miss: (a) English translation at THB 400–600 per page if not yet translated; (b) MFA Consular fees at THB 200 per stamp, +THB 400 for expedited (1-day) service; (c) destination embassy legalization at THB 1,000–5,000 depending on country; (d) door-to-door courier at THB 800–1,500 if you can't travel to Chaeng Watthana yourself.
Hidden costs to add
Real case last month: A client incorporating in Singapore needed notarization of a Director Resolution, Certified Copy of the company affidavit, and a POA for the local corporate secretary — Notary fees THB 4,800 + MFA + Singapore embassy legalization THB 2,700 = THB 7,500 all-in, delivered in 6 business days.
Why IVC prices at the standard rate rather than cheaper: every attorney is a licensed Notarial Services Attorney registered with the Lawyers Council + carries professional indemnity insurance + issues the Certificate of Notarization in the exact format embassies accept. Prices below THB 500 usually indicate an unregistered "certification" that embassies reject at the counter.
