What documents are required for representative office registration?
What documents are required for representative office registration — Company incorporation and amendment filings are made at the Department of Business Development, Ministry of Commerce; foreign shareholding is governed by the Foreign Business Act B.E. 2542 (1999). For work-permit sponsorship the Department of Employment generally looks for THB 2 million of registered capital per foreign position. A company-name reservation at the Department of Business Development stays valid for 30 days from the registrar’s approval. The 90-day report for foreign residents can be filed in person, by post, or through the Immigration Bureau online system. A divorce by mutual consent is registered at the district office, whereas a contested divorce requires a final judgment. Confirm the accepted format first: some offices take paper only, others accept electronically signed files. Documents in a foreign language must be accompanied by a Thai translation when submitted to a Thai government office. Thai Notary Law covers the chain end to end — certified translation, notarial attestation by a Lawyers Council–registered attorney, MFA legalisation and destination-embassy stamping — always with a written scope and quotation first.
Key points
- Confirm the receiving authority’s exact requirement before any translation is certified.
- Foreign-issued documents usually need home-country notarisation or Apostille first.
- Names, dates and company details must match passports and official registries exactly.
- Bundling related services (translation + notary + legalisation + filing) shortens total lead time.
Who this applies to
“What documents are required for representative office registration?” falls within an end-to-end service that combines document preparation, translation, signature certification, consular legalisation and coordination with the destination mission into a single file. The people who search for it are usually preparing a filing against a fixed deadline, recovering from a rejected submission and trying to identify the missed step, or coordinating documents for several people at once.
In practice, each step sits with a different body: the issuing office, the Notarial Services Attorney, the Department of Consular Affairs, and the destination country’s diplomatic mission. Knowing which body owns which step makes it possible to judge how many stages a bundle needs, and which of them cannot be corrected without starting again.
What to prepare before you start
- The complete list the destination requires, with priorities and the filing deadline.
- A recent certified copy of every official document in the bundle.
- Passports for everyone named, so spellings stay identical across the whole set.
- Powers of attorney covering representation at each authority.
- The destination mission’s own requirements: number of sets, binding format and accepted languages.
This is a baseline set. Individual receiving authorities may add requirements, so confirm with the destination body first.
The process, step by step
- Map the whole bundle before starting
Record how many stages each document needs, who certifies it, and what must finish first, so no step has to be redone.
- Normalise every spelling across the set
Check personal names, company names, addresses and dates across the whole bundle before any certification begins.
- Follow the chain in order
Original → translation → signature certification / legalisation → destination mission. Doing these out of order forces a restart.
- Audit the final set before filing
Verify the number of sets, the seals, the binding, and that issue dates are still within the destination’s validity window.
Certification routes compared
| Route | When it applies |
|---|---|
| Notarial Services Attorney certification | For privately drafted instruments — powers of attorney, affidavits, consent letters — signed in the attorney’s presence. |
| Legalisation at the Department of Consular Affairs | Where a foreign authority needs confirmation of the Thai issuing office’s signature and seal, or of the translation. |
| Attestation at the destination mission | Where the destination country requires its embassy or consulate in Thailand to attest the file after consular legalisation. |
| Thailand’s Apostille status | Thailand acceded to the Apostille Convention on 30 June 2026 and it enters into force for Thailand on 28 February 2027. No Apostille is issued in Thailand before that date. |
Why files most often come back
- Processing documents one at a time so spellings drift apart across the bundle.
- Skipping destination-mission attestation where the receiver requires it.
- Letting one document expire while the rest of the set is still in progress.
- A power of attorney that does not cover every authority involved.
- Confusing consular legalisation with an Apostille, which Thailand begins issuing on 28 February 2027.
