Certification tiers are separated up front — agency Certified True Translation, Notary Public seal, MFA consular legalization, and Apostille (not yet available in Thailand — accession deposited 30 Jun 2026, in force 28 February 2027). Government fees follow each authority's published rate, while professional fees are quoted per case by document count and destination, in full before work starts. Tell us where the document will be used and you will get a plan and a price the same business day. Fix three facts before any work starts: the destination country, the exact authority the file goes to, and the language that authority requires. Those three decide the whole certification chain. Caution: processing time depends on each authority's queue, so allow buffer before the date the document is actually needed. Request more than one certified set when several authorities are involved, because most receiving offices keep the certified copy and do not return it. Caution: never unbind, trim or separate pages after an authority has sealed the set — doing so voids the certification. Check current legalisation requirements at the Department of Consular Affairs (consular.mfa.go.th) and Apostille membership at hcch.net.

Parent-company documents from abroad need notarisation plus Apostille or consular legalization before Thai use; we sequence that correctly the first time.
