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 NPT. 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 consular post in Bangkok will only authenticate documents that already carry such an attorney's signature and seal.
NPT 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 Certified Translation by Notarial officer Public use-case bound for Vietnam, the records 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 Certified Translation by Notary Public document types most commonly sent to Vietnam
Based on NPT's internal caseload, the six document types most frequently notarized for Vietnam are: (1) Trademark Assignment Agreement; (2) Marriage Status Affidavit; (3) Parental Consent for Minor Travel; (4) Power of Attorney; (5) Non-Disclosure Agreement (NDA); (6) Power of Attorney.
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 Certified True Copy or Corporate Resolution Notary; translated instruments (transcripts, diplomas, marriage certificates) require a Translator Affidavit certifying the translator's signature, which the notary then attests.
NPT 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 NPT: 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: NPT'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): NPT presents the MFA-authenticated document at the consular post. 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 commercial days, depending on the embassy's calendar. Typical end-to-end cost: THB 5,000–9,000 per record set.

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. NPT's runner team is familiar with each Bangkok consulate'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 NPT 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 Certified Translation by Notary Public accepted in Vietnam on the first try
1) Provide a passport bio-page copy for every signer — the Vietnam diplomatic mission 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 — NPT 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.
