Usually certification in the issuing country (notarisation plus foreign-ministry legalisation or an Apostille, as the recipient accepts) and a Thai translation. Confirm the format the Thai authority accepts first.

Company records for foreign use must be freshly issued by the Department of Business Development and then translated and legalised for the destination. Most destinations accept them only within about six months of issue.
Prefer not to handle the queues yourself, or worried about a rejection? Send us photos of your documents for a free pre-check. We handle the full chain — obtaining certified copies, translation, certification and submission — and keep you updated at each step. Reach us on LINE, phone or email during business hours.
Corporate records must come from the correct source before any certification layer can be added.
| Route | When to use | Certifying authority | Approx. duration | Rejection risk |
|---|---|---|---|---|
| DBD certificate + translation + consular legalisation + embassy | Filing with a foreign government body, e.g. registering a subsidiary | Department of Business Development (DBD) and Department of Consular Affairs | Variable — allow several weeks including embassy queues | Using a certificate older than the destination's accepted issue window |
| Director-certified copies with attorney-notarised signatures | The receiving party is a private counterparty or overseas bank | Notarial services attorney | Usually a few days | Government recipients generally will not accept this format |
Timelines above are practical estimates from live casework and can change with each authority's policy; confirm with the receiving authority before booking travel. If you would rather not test routes by trial and error, our advisers can assess which route fits your case.
Our team has worked on cross-border documents, certified translation and government liaison since 2015. Most rejections we see are not caused by missing paperwork but by choosing the wrong route on day one, so we always start with a case assessment.
We look at your destination, purpose and deadline, then tell you which certification route applies — and which steps you can skip.
Name spelling, consistency across documents, document age and translation format are checked before anything reaches a counter.
We sequence the steps around your appointment or travel date and flag bottlenecks in advance.
We read the refusal reasons, identify the underlying cause, and plan a resubmission that answers what the authority asked for.
