Foreign Business License (FBL) & BOI Promotion in Thailand

For proceedings that go on the record we staff paired interpreters rotating every 20–30 minutes, per international conference practice. 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. Keep a digital copy of the finished certified set so it can be referenced if the destination asks for additional documents or a re-filing. Caution: processing time depends on each authority's queue, so allow buffer before the date the document is actually needed. Private documents such as powers of attorney or contracts must first pass a notarial services attorney before they can enter the legalisation stage. Caution: never unbind, trim or separate pages after an authority has sealed the set — doing so voids the certification. Send scans of every page for review before sending originals; that is when faded seals, passport-spelling mismatches and expired documents can still be corrected. Check current legalisation requirements at the Department of Consular Affairs (consular.mfa.go.th) and Apostille membership at hcch.net.

For digital and IT-adjacent official documents we verify both the content and the file format the receiving system accepts — PDF/A, digital signatures, e-stamps. 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. Talk to the NYC Legal team on any business day — you get a working plan, not a generic price list. Send scans of every page for review before sending originals; that is when faded seals, passport-spelling mismatches and expired documents can still be corrected. Caution: government fees follow the authority's published rate and are separate from professional fees; check the current rate on the official website first. 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: processing time depends on each authority's queue, so allow buffer before the date the document is actually needed. 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.

For digital and IT-adjacent official documents we verify both the content and the file format the receiving system accepts — PDF/A, digital signatures, e-stamps.

Send scans of every page for review before sending originals; that is when faded seals, passport-spelling mismatches and expired documents can still be corrected. Caution: each certification covers only what its own stamp states; it does not make a document automatically acceptable everywhere. Confirm the receiving authority's conditions case by case. The workable order is: check that the source document is complete and legible, translate it, certify the translation, file for legalisation with the Department of Consular Affairs, then obtain the destination embassy's certification — or an Apostille where the destination is a convention party.

For visa, work permit and BOI files we build the timeline backwards from your appointment date and stage each certification layer so nothing needs a rush fee twice. Quotations separate government fees from professional fees line by line, so nothing appears on the invoice that was not in the quote. Tell us where the document will be used and you will get a plan and a price the same business day. The workable order is: check that the source document is complete and legible, translate it, certify the translation, file for legalisation with the Department of Consular Affairs, then obtain the destination embassy's certification — or an Apostille where the destination is a convention party.

Majority foreign ownership in activities listed under the Foreign Business Act B.E. 2542 (1999) requires a licence or certificate, unless the company qualifies under a treaty (such as the Thailand–US Treaty of Amity) or holds BOI investment promotion. Confirm with the receiving authority or counterparty which document they need, how recent it must be and whether a translation is required, before work begins. Watch out: rely on official sources rather than third-party sites, since forms and practice are updated periodically. Verify current requirements with the DBD (dbd.go.th), the Revenue Department (rd.go.th), the BOI (boi.go.th), the DIP (ipthailand.go.th), the PDPC (pdpc.or.th) and the Department of Consular Affairs (consular.mfa.go.th). Professional fees are quoted per case based on scope and documents involved — ask our team by phone, LINE or email. Confirm from the affidavit who the authorised directors are and how many must sign jointly, before drafting any power of attorney or corporate certificate. Verify corporate records at the Department of Business Development (dbd.go.th), tax matters at the Revenue Department (rd.go.th), and legalisation at consular.mfa.go.th.

The Personal Data Protection Act B.E. 2562 (2019) has applied in full since 1 June 2022: controllers need a lawful basis, must give notice of purpose, keep records of processing activities and appoint a Data Protection Officer in the cases the Act specifies, with the PDPC as regulator. A practical order is: settle the shareholding structure and objectives first, gather director and shareholder identity documents, file with the responsible authority, then keep the certified output for the next step. Watch out: inconsistent English spellings of the company name are the most common cause of rejection — keep one spelling throughout. Verify current requirements with the DBD (dbd.go.th), the Revenue Department (rd.go.th), the BOI (boi.go.th), the DIP (ipthailand.go.th), the PDPC (pdpc.or.th) and the Department of Consular Affairs (consular.mfa.go.th).

Under the Accounting Act B.E. 2543 (2000) a Thai juristic person must keep accounts, appoint a bookkeeper, have the financial statements audited by a licensed CPA and submit them to the DBD through DBD e-Filing within the deadline for each accounting period. A practical order is: settle the shareholding structure and objectives first, gather director and shareholder identity documents, file with the responsible authority, then keep the certified output for the next step.

Verify corporate records at the Department of Business Development (dbd.go.th), tax matters at the Revenue Department (rd.go.th), and legalisation at consular.mfa.go.th.

Corporate documents for overseas use normally start with a certified DBD extract, then translation, then legalisation by the Department of Consular Affairs and/or the destination embassy; Thailand's accession to the Apostille Convention took effect on 2 December 2025, which changes the chain for member states.
