How much does it cost to legalise a Birth Certificate for the Mongolia 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 Mongolia legalization take?

Thai MFA 2–3 days + Embassy of Mongolia 10-21 วัน — 7–21 business days end to end, with express options where the mission allows.

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

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

Does the Birth Certificate need to be translated first?

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

What is a legalised Birth Certificate used for in Mongolia?

Visa and immigration filings, marriage, study, employment, pensions and legal matters. Popular documents at this mission: Apostille, Mongolian Translation.

Can I apostille a Thai Birth Certificate instead of using the Mongolia embassy?

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

Do I need to appear in person at the Mongolia 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 Birth Certificate be for Mongolia?

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

What does a legalised Birth Certificate for Mongolia cost in total?

Typically THB 6,000–12,000 all-in: Mongolia 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 Birth Certificate outside Thailand?

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

Legalising a Thai Birth Certificate for Mongolia

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

Why the legalization chain is required

The reason the chain exists is verification of authenticity across jurisdictions. The Mongolia embassy will not read your Thai Birth Certificate directly; instead it relies on the Thai MFA to vouch for the signature and seal of the Thai issuing authority (or the certified translator). This is why skipping the MFA step is the single most common cause of embassy rejection — the mission simply has nothing to authenticate against.

Certified translation requirements

Translation is not optional cosmetic work — it is part of the legal instrument. For Mongolia, the Birth Certificate 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

Budget realistically: the Embassy of Mongolia charges สอบถามเจ้าหน้าที่ for authenticating a Birth Certificate, the Thai MFA charges roughly THB 200–400 per document (express ~THB 800), certified translation runs about THB 800–1,500 per page, and the NYC Legal all-inclusive service fee is สอบถามเจ้าหน้าที่. A typical single Birth Certificate therefore lands in the THB 6,000–12,000 range once every counter is paid.

Realistic timelines you can plan around

The Mongolia mission's own processing (10-21 วัน) is the least controllable part of the timeline, which is why we start translation and MFA legalization immediately and submit to the embassy the moment the MFA stamp is dry. Total realistic turnaround for a Birth Certificate is 7–21 business days; we give you an honest date at quotation, not an optimistic one.

What a legalised Birth Certificate is used for

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

Common mistakes we help you avoid

Rejections usually come from small, avoidable errors: an expired Birth Certificate, a translation that omits an official annotation, a name that reads differently from the passport, or a document submitted to the Mongolia embassy out of sequence. We verify document freshness, translation completeness and stamp order before anything is lodged.

Why work with NYC Legal

Doing this yourself means multiple trips across Bangkok, queueing at the MFA and the Mongolia mission, and risking a wasted day if any detail is off. We consolidate the entire Birth Certificate legalization into one managed service, submit at ซอยเอกมัย on your behalf, and return the document ready to file — in Thailand or shipped internationally.
