How much does it cost to legalise a Affidavit for the Vietnam embassy?

Embassy consular fee สอบถามเจ้าหน้าที่ + Thai MFA legalization (THB 200–400) + certified translation (THB 800–1,500/page) + NYC Legal service fee สอบถามเจ้าหน้าที่ — typically THB 6,000–12,000 all-in.

How long does the Vietnam legalization take?

Thai MFA 2–3 days + Embassy of Vietnam 7-14 วัน — 7–21 business days end to end, with express options where the mission allows.

Do I need the Thai MFA stamp before the Vietnam embassy?

Yes — every Thai document must be legalised by the Department of Consular Affairs (Chaeng Watthana) before the Embassy of Vietnam will authenticate it.

Does the Affidavit need to be translated first?

In most cases yes — the Affidavit must be translated into a language the Vietnam mission accepts, certified by an MFA-recognised translator, then legalised together with the original.

What is a legalised Affidavit used for in Vietnam?

Visa and immigration filings, marriage, study, employment, pensions and legal matters. Popular documents at this mission: Consular Legalization, Notarized Translation.

Can I apostille a Thai Affidavit instead of using the Vietnam embassy?

No. Thailand is not part of the Hague Apostille system for this route, so a Thai Affidavit for Vietnam must go through Thai MFA legalization and then Embassy of Vietnam authentication — not an apostille.

Do I need to appear in person at the Vietnam embassy?

In most cases no — NYC Legal submits and collects on your behalf with an authorisation letter. A few document types (e.g. certain declarations) may require your signature, and we will tell you in advance if so.

How recent must my Affidavit be for Vietnam?

Many missions expect the underlying Affidavit to be issued within the last 3–6 months. We confirm the current requirement for the Vietnam embassy at booking so you don't legalise a document that will be rejected as stale.

What does a legalised Affidavit for Vietnam cost in total?

Typically THB 6,000–12,000 all-in: Vietnam consular fee (สอบถามเจ้าหน้าที่), MFA legalization (THB 200–400), certified translation (THB 800–1,500/page) and our service fee (สอบถามเจ้าหน้าที่). You get an exact quote up front.

Can you ship the finished Affidavit outside Thailand?

Yes. We deliver a scanned PDF immediately and courier the legalised original by EMS or DHL to any address in Vietnam or worldwide.

Legalising a Thai Affidavit for Vietnam

If you are relocating to, studying in, marrying in, or doing business with Vietnam, your Thai Affidavit will only be accepted once it carries both the Thai MFA legalization stamp and the Vietnam embassy authentication. We prepare the certified translation, secure the consular stamp in Chaeng Watthana, and submit the file to the Vietnam mission at ถนนวิทยุ on your behalf.

Why the legalization chain is required

Each layer in the legalization chain authenticates the layer beneath it. The certified translation is verified by the translator's declaration; the MFA authenticates the translator's registered signature; and the Embassy of Vietnam authenticates the MFA. Break the chain anywhere and the Vietnam authorities can lawfully refuse the Affidavit, even if the underlying facts are correct.

Certified translation requirements

Translation is not optional cosmetic work — it is part of the legal instrument. For Vietnam, the Affidavit translation must mirror every seal, marginal note and signature block of the Thai original. Our translators reproduce the full layout, then attach a signed certificate of accuracy that the Legalization Division will authenticate.

Transparent, itemised pricing

The Vietnam embassy fee for a Affidavit (สอบถามเจ้าหน้าที่) is set by the mission and can shift with exchange rates, so we confirm it at booking. Add MFA legalization, certified translation, and our transparent service fee (สอบถามเจ้าหน้าที่) and the all-in figure is usually THB 6,000–12,000 for one document — with volume discounts for family or corporate batches.

Realistic timelines you can plan around

Plan for 7-14 วัน at the Vietnam embassy stage, on top of 2–3 business days at the Thai MFA and 1–3 days for certified translation. Realistically a single Affidavit takes 7–21 business days end to end. If you have a visa interview or filing deadline, tell us first — express MFA and priority embassy handling can compress this materially where the mission allows it.

What a legalised Affidavit is used for

Foreign nationals typically need a legalised Affidavit when dealing with Vietnam government offices, courts, universities, employers or banks — anywhere the receiving party must trust a Thai record. At this mission the highest-volume documents are Consular Legalization, Notarized Translation, and we handle each with the correct chain for its purpose.

Common mistakes we help you avoid

The most frequent rejections we prevent: submitting the Affidavit to the Vietnam embassy before the MFA stamp; name spellings that differ from the passport; an outdated document (many missions want issuance within 3–6 months); a translation missing a seal or marginal note; and photocopies where a certified true copy or original is required. We pre-flight every file against the Vietnam mission's current checklist.
