MFA government fees are THB 200 per copy (2-day standard) and THB 400 per copy (1-day express). Our bundled service fee starts at THB 1,500 and varies by document type and destination country. Thailand is not a party to the Hague Apostille Convention 1961, so every Thai public document used overseas must go through the legalization chain: origin agency → MFA → destination consulate. Thailand is not a party to the Hague Paperwork attestation Convention 1961, so every Thai public document used overseas must go through the legalization chain: origin agency → MFA → destination diplomatic mission.
Required documents: original document already certified by the origin agency, certified translation in English or destination language (if needed), translator's certification statement from a registered translator, original Thai national ID card and copy, Power of Attorney with THB 30 stamp duty (if not appearing in person), and a purpose letter from the destination authority.
Legalization of Revenue Department tax documents — Por.Ngor.Dor.91, Por.Por.20, and Tax Residency Certificate. Used for international tax relief and double-tax-treaty benefits abroad.
MFA government fees are THB 200 per copy for standard (2-business-day return) and THB 400 per copy for express (1-enterprise-day return). Our bundled service fee covers document running, follow-up, translation, consulate submission, and DHL/FedEx shipping — starting at THB 1,500 for simple cases and THB 5,000–10,000 for multi-agency documents.
A Notarial Services Attorney certifies signatures, identity, or copies as the first link inside Thailand. MFA Nitikorn certifies that the origin agency's stamp/signature (including the Notary's) is genuine. Consular post Legalization is the final step where the destination diplomatic mission authenticates the MFA seal. Documents become usable abroad only after all three layers are complete.
A fully MFA-legalized document carries the red Department of Consular Affairs seal, the Head of Legalization Section's signature, a reference number, an issue date, and explicit wording stating that only the origin agency's stamp and signature are certified. The reference number can be verified in real time on the MFA online verification system.
MFA accepts translations from registered translators or recognized official rendering companies — list at consular.mfa.go.th. Translations must match the source verbatim including reference numbers, dates, signatures, and stamps. Common languages: English, French, German, Chinese, Japanese, Korean, Arabic, Spanish, Italian, Portuguese.
Book online at qlegal.consular.go.th. Chaeng Watthana hours: Mon–Fri 08:30–14:30 for filing (overall service window 09:00–16:00). Closed weekends and public holidays. Regional branches with legalization service: Chiang Mai, Khon Kaen, Songkhla, and Phuket.
After MFA, the final step is filing at the destination consulate in Bangkok. Each diplomatic mission has its own turnaround, fees, and requirements — typically 3–10 business days. Some embassies (China, Germany, France) require advance online appointments. Our team books the slot and submits on your behalf when embassy rules permit.
Clients who cannot travel to MFA Chaeng Watthana can engage us under a Power of Attorney with THB 30 stamp duty, plus copies of both parties' Thai national IDs. We handle every step — filing, follow-up, document collection, and onward diplomatic mission submission.
Common reasons for rejection or delay: missing origin-agency certification, translation not matching the source, unclear stamps/signatures, expired documents (e.g. Single Status past 6 months), or using a translator not on the MFA list. A pre-filing review with our team eliminates these risks.
Foreign nationals living in Thailand can use our MFA legalization service for personal documents created in Thailand — Thai marriage certificate to a Thai national, child birth certificate, Power of Attorney, Affidavit, etc. — before sending them home. Same workflow as Thai nationals, with passport and visa copies attached.
Once the legalization chain is complete, we ship via DHL or FedEx Express to any destination worldwide in 3–7 days with full tracking. Postage starts at Request a quote to nearby countries and Request a quote to long-haul destinations.
Thailand uses a 3-step Legalization Chain (origin → MFA → diplomatic mission), while Hague Apostille Convention 1961 member states use a single-step Legalization from a Competent Authority — directly accepted by every member country. Thailand is not yet a member, so the MFA developed the authentication chain to ensure Thai documents are accepted in every destination country.
The MFA online booking portal is consular.mfa.go.th — public slots open 7-14 days out. Express service is walk-in only before 08:00 on business days, capped at 50 tickets/day, with a Request a quote/doc surcharge. We hold reserved slots through a corporate account, cutting turnaround to 1-2 enterprise days.
Certifying copies of Thai government records (house registration, ID, marriage certificate, birth certificate) requires the original brought in for verification. We certify Thai copies and English translations in one stop before MFA submission — bundled Request a quote/doc.
MFA regional branches (Chiang Mai, Khon Kaen, Songkhla, Phuket) handle basic legalization with shorter queues than Bangkok by 2-3 business days, but cannot process certain corporate documents that require Chaeng Wattana HQ. We route between channels case-by-case.
Signatures sometimes don't match the MFA database (officer changed; signature not yet updated in the system). The fix is to return the document to the issuing authority for a signature update or fresh re-issue under the current signatory — adds 5-10 business days.
MFA legalization is performed at the Department of Consular Affairs, Chaeng Watthana Soi 19 (opposite the Government Complex) or at regional Passport Service offices. The five core steps: (1) bring the original document already certified by its origin authority (district office, university, DBD, court), (2) confirm whether translation is required first, (3) submit the application form, (4) pay Request a quote per copy (Request a quote express), (5) collect the document with the Department of Consular Affairs red seal.

|---|---|---|---|
| 1. Obtain the original or certified copy of the Thai document | Issuing agency (district office, DOPA, etc.) | ID/passport + request form | approx. 1–5 working days |
| 2. Translate the document exactly | Translator accepted by the Department of Consular Affairs | Original + passport copy (matching name spelling) | approx. 1–3 working days |

Durations are estimates and depend on the responsible authority's queue. Always confirm current requirements with the receiving body before filing.
The MFA certifies the signature of the issuing official, not the content, so private paperwork must first obtain notarial certification by a licensed Thai attorney; if the file is bound for use abroad, plan it together with the destination embassy's attestation so the document only travels once.
Written from the competent authority's published rules, not marketing copy.
A legalised document usually continues to the destination embassy, unless the destination accepts an Apostille. The receiving country sets that order, not the applicant.
Completing the whole chain in one pass reduces the number of filing rounds, which is the real time cost in this kind of work.

Turnaround is not fixed: it depends on the queue and rules of Legalization Division, Department of Consular Affairs, MFA, the document type, and the receiving office abroad. For that reason we do not publish a fixed figure. Plan a buffer before your real deadline and ask our staff by phone, LINE or email for the current queue before booking travel.

Our staff can clarify by phone, LINE or email. This is general guidance; requirements and processing times change — verify with the competent authority before filing.

Thailand deposited its instrument of accession to the 1961 Hague Apostille Convention on 30 June 2026, and the Convention enters into force for Thailand on 28 February 2027. Until that date, Thai documents used abroad still require legalisation by the Department of Consular Affairs (Ministry of Foreign Affairs) followed by legalisation at the destination country's embassy.
Today (before 28 February 2027) Thai documents used abroad still follow the existing chain: certified translation → notarial attestation → legalisation by the Department of Consular Affairs (MFA) → legalisation at the destination country's embassy in Thailand.
Once the Convention enters into force for Thailand on 28 February 2027, Thai public documents sent to any of the 130 Contracting Parties will require only a single Apostille from the Department of Consular Affairs, with no further embassy legalisation.
