Corporate document advisory for cross-border operations
Answers for HR, legal and procurement teams preparing document packs for overseas assignments, branch registration, cross-border contracts and international tenders, covering certification sequencing, copy counts and deadline control. (25+ search topics covered)
What is the certification order for company documents?
Obtain certified issues from DBD or the Revenue Department, translate into the required language, legalise at the Department of Consular Affairs, then obtain embassy attestation where the destination requires it.
Can a board resolution be signed electronically for legalisation purposes?
For legalisation, the Department of Consular Affairs works from a physical document bearing verifiable signatures and, where applicable, the company seal. An electronically signed resolution therefore usually has to be reissued in wet-ink form, or accompanied by a notarial attorney's certification of the signatory. Confirm the format with the receiving authority first, since some accept a certified printout while others require original execution.
How much of a Thai company may foreigners own?
Activities listed under the Foreign Business Act are restricted unless a licence or certificate is obtained, or rights arise under a treaty or investment promotion. Nominee shareholding is an offence, so the structure must be designed correctly from the outset.
How many copies should we prepare?
At least one more than the recipient asks for. Legalised documents are usually retained by the recipient, and extra copies must restart the full chain.
Do foreign shareholders' documents need to be legalised for a Thai company registration?
Where a shareholder or director is a foreign company, registrars commonly require its corporate documents to be legalised in the country of issue and translated into Thai. For individuals, passport copies certified abroad may be requested. Requirements differ between the registrar, the bank opening the account, and any licensing authority involved, so collect all three lists before ordering certifications.
Representative office or limited company?
A representative office may only carry out the non-revenue activities permitted by law, such as sourcing and reporting to head office. A limited company may trade within its registered objectives and licences. Choosing wrongly means dismantling and re-registering.
Do company affidavits expire?
Most recipients require issuance within a set window before submission. Time the request to the actual filing date rather than obtaining it far in advance.
What corporate documents does a foreign parent need for a Thai subsidiary?
Typically the parent's certificate of incorporation, memorandum or articles, a list of authorised directors, a board resolution approving the investment, and a power of attorney for the person acting in Thailand. Foreign-issued documents complete the authentication chain and are filed with Thai translations at the Department of Business Development. The usual time sink is inconsistent Thai transliteration of the company and director names across documents — agree a single name key at the outset and apply it to every translation.

Practical Q&A
Practical questions · Near me / DIY / Required documents
What is the route for Thai company documents used abroad?
Obtain the company affidavit, shareholder list (BorJor 5) or latest memorandum from the Department of Business Development, translate into the language the destination requires, then legalise at the Legalization Division of the Department of Consular Affairs. If the destination is not an Apostille Convention party, the destination country's embassy certifies last.
Must the company affidavit be freshly issued?
Most receiving authorities set a validity window counted from the registrar's issue date, commonly measured in months. Check the recipient's requirement before ordering copies: filing an out-of-date affidavit is a frequent rejection cause, and legalisation cannot revive an expired document.
How is a corporate power of attorney certified?
An authorised director signs before a Notarial Services Attorney, attaching a current company affidavit that evidences signing authority. The signed POA then goes to the Department of Consular Affairs and, where required, the destination embassy. Ask our team by phone, LINE or email for the order that applies to your country.
Practical advice & cautions
Business, tax and legal work: advice and cautions
Before you start
Check for sector-specific licences
Some activities need a licence from a specialist regulator before operating. Verify at the planning stage.
Keep complete source documents
Tax invoices, receipts and contracts should be filed systematically per accounting period to support any later audit.
Use bilingual contracts with a governing version
Cross-border contracts should state which language version prevails and how disputes are resolved.
Separate personal and company banking
Mixed accounts complicate financial statements and tax explanations, and cause problems when bank evidence supports a visa or work permit.
Common reasons documents get rejected
Outdated company certificates
Certificates submitted should be freshly issued and consistent with the current register, or the receiving authority will refuse them.
Failing to file changes
Changes of director, address or capital must be filed within the statutory period; omissions create mismatches that block other applications.
Wills that ignore cross-border assets
Assets in different countries may fall under different succession rules; ensure multiple wills do not contradict each other.
Treating a contract translation as legal advice
A translation conveys wording but does not assess legal risk. Have a lawyer review the substance before signing.
Requirements differ by authority and destination country and can change. Confirm current conditions with the receiving authority, or ask our team by phone, LINE or email.
