Legalising Foreign Corporate Documents for a Thai Subsidiary or BOI File

A foreign parent — a Singapore ACRA-registered holdco, a Delaware C-corp, a UK Companies House entity — that intends to open a Thai branch, register a representative office, or apply for a BOI promotion certificate has to lodge a chain the Thai Department of Business Development (DBD) recognises: a home-country certificate of incorporation, board resolution appointing the Thai director, and specimen signatures, each notarised at origin, apostilled or embassy-legalised, translated into Thai by a registered translator, and re-stamped by the Thai MFA Consular Section before DBD will accept the filing under Section 8 of the Foreign Business Act B.E. 2542.

FAQ

Do we need original signatures or are e-signed board resolutions accepted?

DBD accepts wet-ink originals or e-signatures backed by a qualified electronic signature under the parent's home law (US ESIGN, EU eIDAS, SG ETA). We annotate the translator's memo with the e-signature framework so DBD reviewers do not query it.

How current must the certificate of incorporation be?

DBD wants the underlying home-country certificate dated within ninety days of Thai lodgement. If the timeline slips, we re-order and re-legalise rather than let the filing be rejected.

Can a single translation cover both DBD and BOI lodgement?

Yes — we prepare the Thai rendering to BOI's One-Stop Service Centre format, which is a strict superset of the DBD template, so the same translation clears both counters without re-typing.
