The company affidavit is issued by Department of Business Development. Use a freshly issued extract; destinations usually impose a recency limit. It is then translated to the standard Vietnam accepts, legalised at Consular Affairs and attested at the destination mission where the receiving body requires it.

A Vietnamese translation certified as the receiving authority requires
File the original with its translation at the Department of Consular Affairs, MFA.
Attest at the Vietnam mission in Thailand where the receiving authority requires it.
Anyone submitting a company affidavit in support of a visa application, a civil-status registration, an employment file, or a court or registry filing in Vietnam is normally required to submit both the Thai original issued by Department of Business Development and a properly certified translation. Filing only the translation is one of the most common reasons a file is returned unread.
Foreign nationals sending a company affidavit back for use in Vietnam — to prove family status, claim an inheritance, apply for a benefit or confirm an address — should first confirm whether the receiving body requires legalisation by the Department of Consular Affairs, and whether the Vietnam mission in Thailand must attest the document afterwards.
Employers posting staff to Vietnam, or filing contract and registration documents, should prepare the whole bundle as a single set so that personal names, company names and spellings match on every page. A one-letter discrepancy between passport and certificate routinely forces the entire certification chain to be restarted.
Before starting the certification chain for Vietnam, gather the following in one pass. Doing so keeps the file to a single round and avoids having to re-issue documents later.
Each certification answers a different question, and choosing the wrong one costs a full round trip. For a company affidavit intended for Vietnam, the differences are as follows.
A Vietnamese translation certified as the receiving authority requires
Vietnam is outside the apostille system, so Thai documents pass through the Department of Consular Affairs and are then legalised at the Vietnamese Embassy before use
In practice, confirm the required format with the receiving authority in writing before starting: two bodies in the same country often differ. Some accept a translation certified in Thailand, while others insist on a translator registered in the destination country itself.
Tell us the receiving authority in Vietnam, the purpose of the document, your filing deadline and the certification format it specifies, and send a photo of the company affidavit and passport page for a first review. We will map out only the steps your file actually needs.
Obtain the company affidavit from Department of Business Development, translate it to the accepted standard, have it legalised by the Department of Consular Affairs, then attested at the Vietnam mission in Thailand where the receiving body requires it.
Use a freshly issued extract; destinations usually impose a recency limit
Thailand acceded to the 1961 Hague Apostille Convention on 30 June 2026 and it enters into force for Thailand on 28 February 2027, so no Thai Apostille is issued yet, so no Apostille is issued in Thailand. The working route is certified translation, legalisation by the Department of Consular Affairs (MFA), and then attestation at the destination country’s mission in Thailand where the receiving authority requires it.
A Vietnamese translation certified as the receiving authority requires, and every part of the document must be translated, including stamps, signatures and marginal notes.
The Vietnamese Embassy in Thailand and the receiving authority in Vietnam
Vietnam is outside the apostille system, so Thai documents pass through the Department of Consular Affairs and are then legalised at the Vietnamese Embassy before use
It is a public record issued by a state authority, so it can enter consular legalisation directly once an accurate translation is attached.
Connect the names as a chain using change-of-name records or a spelling confirmation, then translate and legalise them together as one bundle.
