Why Thai documents bound for Vietnam must first pass a Thai Notary Public
Vietnam is one of the most frequent destinations for documents notarized at Thai Notary. Any Thai-issued instrument used officially in Vietnam must travel through the "international document recognition chain" so that the receiving authority can verify that the record was executed by a person or entity with genuine authority. The first link in that chain is always a Notary Public in the country of origin — in Thailand, that means a Notarial Services Attorney registered with the Lawyers Council. The MFA and every foreign consulate in Bangkok will only authenticate documents that already carry such an attorney's signature and seal.
Thai Notarial officer is registered with the Department of Business Development (registration no. 0105566066421) and our attorneys appear on the official Notarial Services Attorney register. The MFA and the Diplomatic mission of Vietnam can verify our signatures against that register at any time, which is why documents leaving our office complete the chain reliably — we do not see rejections caused by an unrecognized notary.
For the Affidavit, Oath & Sworn Declaration use-case bound for Vietnam, the instruments we notarize most often are Work permit · Investor visa · Marriage registration · Birth registration of child. Our team has processed more than one thousand documents per year destined for Vietnam and is familiar with the exact format the receiving authorities expect, keeping the rejection rate below 0.5%.
Six Affidavit, Oath & Sworn Declaration document types most commonly sent to Vietnam
Based on Thai Notary's internal caseload, the six document types most frequently notarized for Vietnam are: (1) Non-Disclosure Agreement (NDA); (2) Corporate Board Resolution; (3) Certified Copy of House Registration (Tabien Baan); (4) Parental Consent for Minor Travel; (5) Certified True Copy of Passport; (6) Parental Consent for Minor Travel.
Each category requires a specific notarial form: personal instruments (power of attorney, consent to travel, status affidavits) usually take the Acknowledgement or Jurat form; corporate instruments (board resolutions, articles, specimen signatures) take Authenticated True Copy or Corporate Resolution Notary; translated instruments (transcripts, diplomas, marriage certificates) require a Translator Affidavit certifying the translator's signature, which the notary public then attests.
Thai Notary maintains a library of over 50 sample documents previously accepted by Vietnam authorities. Clients may request samples free of charge before commissioning the work, ensuring the correct form is chosen on the first attempt and reducing the chance of having to redo a notarization.
Step-by-step legalization workflow for Vietnam
Vietnam is not yet a party to the Hague Apostille Convention (non-Hague jurisdiction), so the full three-step legalization chain remains in force:
Step 1 — Notary Public at Thai Notary: a Notarial Services Attorney executes the notarization either at our Lat Phrao 95 office or at the client's location. Time required: 30–60 minutes.
Step 2 — MFA authentication, Department of Consular Affairs, Chaeng Watthana: Thai Notarial officer's runner team files the document at the MFA (1-day express or 2-day standard). The MFA verifies the attorney's signature against its register and stamps its own authentication.
Step 3 — Consular post of Vietnam (สถานทูตเวียดนาม, Wireless Road, Pathum Wan): Thai Notary presents the MFA-authenticated document at the diplomatic mission. Processing time is 3–5 business days; fees follow each mission's published schedule. Some embassies require advance appointments, others accept walk-ins — our team handles whichever protocol applies.
Total wall time: 5–14 enterprise days, depending on the embassy's calendar. Typical end-to-end cost: THB 5,000–9,000 per instrument set.
Real engagements Thai Notary has handled for Vietnam
Case 1 — A foreign national marrying a Thai citizen plans to register the marriage in Vietnam; the Single Status Affidavit issued by the Thai district office must be translated, notarized and legalized. Thai Notary prepared the documents in the format required by the receiving authority, coordinated the consular post and MFA queues, and delivered the legalized set within seven business days.
Case 2 — A foreign national marrying a Thai citizen plans to register the marriage in Vietnam; the Single Status Affidavit issued by the Thai district office must be translated, notarized and legalized. Thai Notary issued the underlying affidavit, prepared the certified translation with a Translator Affidavit in the format Vietnam requires, and delivered the package in time for the client's departure date.
Case 3 — An expatriate professional relocating to Vietnam needs a notarized Translator Affidavit plus certified copies of educational credentials before the employer files for the work permit. Thai Notary public's corporate team advised on board-resolution drafting, specimen-signature procedures and prepared the full corporate notarization bundle accepted by the registrar in Vietnam.
Case 4 — A foreign national marrying a Thai citizen plans to register the marriage in Vietnam; the Single Status Affidavit issued by the Thai district office must be translated, notarized and legalized. Real-time status updates were issued by LINE/WhatsApp at every milestone — notarization, MFA, consulate, dispatch — so the client never had to chase progress by phone.

Embassy and authority coordination in Vietnam
Documents already authenticated by the MFA must be presented at the สถานทูตเวียดนาม, located in Wireless Road, Pathum Wan, Bangkok. The consulate's standard processing time is 3–5 business days. Thai Notary's runner team is familiar with each Bangkok consular post's protocols — walk-in versus appointment-only, fee schedules, accepted document formats — which materially reduces the chance of rejection on minor format issues.
Clients outside Bangkok do not need to travel: send the originals to our Lat Phrao 95 office by EMS or Kerry and Thai Notary executes the notarization, MFA filing, embassy legalization and final dispatch — either back to the client or onward to Vietnam by DHL International.
Six tips to get Affidavit, Oath & Sworn Declaration accepted in Vietnam on the first try
1) Provide a passport bio-page copy for every signer — the Vietnam consulate uses it to verify name consistency across the document set.
2) State the intended purpose clearly (e.g. "for use in a work-permit application", "for submission to the receiving government agency") — the appropriate notarial form depends on purpose, even for the same underlying document.
3) Check record validity windows — several embassies (notably many European missions) will not accept Single Status Affidavits or household registration extracts older than six months.
4) Make sure the translation matches the receiving authority's requirements — Thai Notary has native in-language translators in-house and can issue the Translator Affidavit on the same day.
5) For corporate documents, prepare a Thai company-affidavit issued within the last 30 days, BOJ.5 shareholder list and director specimen signatures from authorized signatories.
6) Build a 7–14 day buffer before any hard deadline — MFA and diplomatic mission schedules slow down around Thai public holidays as well as Vietnam national holidays.
Frequently asked questions
What steps does a Thai notarized document need before it can be used in Vietnam?
Vietnam is not yet a party to the Hague Apostille Convention, so the document must complete the full three-step legalization chain: (1) notarization by a registered Thai Notarial Services Attorney, (2) authentication by the Department of Consular Affairs (MFA, Chaeng Watthana), and (3) legalization at the Consulate of Vietnam in Bangkok. Thai Notary handles all three steps end-to-end.
What is the typical total cost for a notarized package destined for Vietnam?
Notary service starts at THB 1,500 per set, certified translation runs THB 500–1,200 per page depending on language, MFA authentication is THB 200 per document plus the official fee, and consulate legalization fees vary by mission (typically THB 800–3,000 per document). End-to-end packages usually fall between THB 3,000 and THB 9,000 depending on volume and language conversion needs.
How long will the entire process take for Vietnam?
Notarization 1 day, MFA authentication 1–2 business days, then Vietnam consulate legalization according to that mission's schedule (typically 3–10 commercial days). Total runway: 5–14 business days. Thai Notary runs the consular post queue on your behalf so you do not have to travel.
Can your notary travel to my home or office to take the signature?
Yes. Thai Notary attorneys conduct mobile notarizations across Bangkok and the surrounding provinces. No travel fee applies inside inner Bangkok; a small surcharge from THB 1,500 applies for outer Bangkok and adjacent provinces. We also accept original documents via EMS, Kerry or Grab, and we can ship completed packages to Vietnam by DHL or EMS International.
Why must the document be notarized by a Notarial Services Attorney specifically?
Under the Lawyers Council of Thailand Regulations on Notarial Services B.E. 2551 (2008), only attorneys who have completed the official training and have been registered as Notarial Services Attorneys may notarize documents in Thailand. The MFA and Vietnam diplomatic mission verify the attorney's signature against this register — documents notarized by an unregistered lawyer will be rejected at the MFA stage.
Does the document need to be translated before it is presented in Vietnam?
English is typically the broadest-accepted target language. Some agencies in Vietnam may additionally require a translation into the local language — Thai Notary's in-house certified translation desk advises based on the receiving authority.
