An Apostille on a Thai corporate document is a certificate issued by the Department of Consular Affairs of the Thai Ministry of Foreign Affairs confirming the signature and seal on that document, so a Hague member state can rely on it without further embassy endorsement. Company records are normally obtained in certified form from the Department of Business Development, and private instruments such as board resolutions and powers of attorney are notarised first. Whether the destination accepts an Apostille for a given document, and in which language, is decided by the receiving authority.

Frequently asked questions — Thai corporate Apostille

Which Thai authority issues the Apostille on corporate documents?

The Department of Consular Affairs of the Thai Ministry of Foreign Affairs is the competent authority for Apostille and legalization of Thai public documents, including company records certified by the Department of Business Development.

Can a private company document be apostilled directly?

An Apostille is issued on public documents. A purely private document such as an internal board resolution normally has to be turned into a public document first, for example by notarisation by a notarial services attorney, before it can enter the Apostille route.

Do corporate documents still need embassy legalization?

It depends on the destination. Where the receiving country is a Hague Apostille member and accepts the Apostille for the document in question, a further embassy step is usually unnecessary. Non-member destinations still require embassy or consulate endorsement after the Ministry step.

Does the translation have to be done before submission?

Where the receiving authority works in a language other than Thai, a translation is normally attached and certified together with the document. Preparing the translation before lodgment avoids a second submission cycle.

How recent must a DBD company affidavit be?

Many receiving authorities and banks require a company affidavit issued within a limited recent period. The exact window is set by the receiving party, so confirm it before ordering the affidavit from the Department of Business Development.

Are originals required, or are copies accepted?

Certification is normally performed on originals or on copies certified by the issuing office. Plain photocopies are generally rejected, so request additional certified sets from the issuer in advance.

Can a representative lodge the documents on the company's behalf?

Yes. A signed power of attorney together with identification of the authorised director and the representative is normally required, and the counter may ask for the company seal where the company uses one.

How do we get a quotation?

Send scans of the corporate documents and the name of the destination country to LINE @NAATI or ilc@thainotary.co.th. We review the set and quote per case after confirming the required chain.

A working guide to thai apostille for corporate documents in Thailand

Thai Apostille for Corporate Documents is scoped by a senior specialist during a free intake on LINE Official @NAATI before any paperwork moves. Fees, timelines, required documents, and destination-authority acceptance criteria are all agreed in writing first — a discipline that materially reduces re-work and rejected filings. Every Thai corporates transacting in Hague-convention states matter is scoped by a senior specialist on LINE Official @NAATI or by email at ilc@thainotary.co.th before any file moves.

The document set most often audited on Thai corporates transacting in Hague-convention states matters here includes DBD affidavit, shareholder list, board resolution, power of attorney, audited financials, certified translation. Deliverables are formatted to the acceptance criteria of the Department of Consular Affairs (MFA) — Apostille counter.

How the workflow runs end-to-end

Because the audit, translation, notarization, and MFA/embassy legs are all executed under one project number, hand-offs never introduce version drift. What ships to the client is the same file that was audited on day one, with every intermediate stamp attached in the correct order.

Who this service is for

The service handles both one-off private clients (a marriage abroad, a police check for a new employer, a university transcript for a masters programme) and recurring enterprise workflows (monthly work-permit renewals, quarterly BOI reports, ongoing IP filings across multiple jurisdictions).

Coverage, fees, and turnaround

For clients outside Bangkok the pickup and return legs are quoted upfront and paid at cost, so the professional fee stays unaffected by geography. Regional hubs — Chiang Mai, Phuket, Pattaya, Rayong, Khon Kaen, Hat Yai — have partner offices that shorten the round-trip by 24–48 hours versus a pure courier route.

Quality assurance and confidentiality

If a receiving authority ever rejects a deliverable for a translation or certification defect, we re-issue the corrected file at no additional charge and refund any government fees that must be repaid — a policy written into our standard engagement letter, not a discretionary courtesy.

Documents usually required

  • Freshly issued original Thai civil or corporate record from the issuing office
  • Complete English translation of every page, with the translator's statement of accuracy
  • Copy of the document holder's passport or Thai national ID card
  • Power of attorney with ID copies of both parties if someone else files on your behalf

Common reasons a bundle is rejected

  • Countries outside the Apostille Convention still need a further endorsement at the destination embassy.
  • Translations that use an unofficial English name for a Thai agency are sent back for correction.
  • Spell every name exactly as it appears in the passport, across every document in the same bundle.

Prefer not to handle the chain yourself? Send the scans and we run every step for you, from translation to the final endorsement.

How the process runs — Legalization at the Department of Consular Affairs

  1. Obtain a freshly issued original from the office that produced the record and check that every page is present.
  2. Prepare a complete translation with the translator's statement of accuracy attached.
  3. File for legalization at the Department of Consular Affairs, Ministry of Foreign Affairs, with the original and the translation together.
  4. Complete the next certification layer required by the destination country — Apostille, or legalization at that country's embassy in Thailand.
  5. Collect the finished bundle, scan a full copy for your records, then submit it in the format the receiving authority specifies.

Fees and processing times are set by each authority and vary by document and destination — confirm them with the responsible agency.

Handling it yourself vs letting iLC run it

AspectDoing it yourselfWith iLC
Working out which steps applyYou read each authority's rules yourself, and usually learn a step was missing only after the bundle is refused.Our advisers review the documents before work starts and sequence translation, notarisation, MFA, and embassy in one pass.
Time spent filingRepeat trips to each office, queueing and collecting in person.We file on your behalf; you send scans and receive the finished set by post or courier.
Risk that the translation is refusedAgency names, job titles, and the certification wording often do not match what the receiving office accepts.We use terminology and certificate formats the receiving authority has accepted before, with two-stage proof-reading.
If the bundle is rejectedYou diagnose the cause and refile yourself, losing a full cycle.We identify the cause, correct it, and refile without you starting over, with progress reported along the way.
