Documents Required

Original document to be certified (or freshly issued certified copy within validity window)
Copy of national ID or passport, signed and dated as a true copy
Power of attorney (if a representative will handle it) with a 30 THB revenue stamp
Destination details: country, receiving authority, purpose, and required deadline

Step-by-Step Process

1. Send scanned copies of source documents to us via LINE/email for free initial review.
2. Our team confirms eligibility, issues a written quote and a guaranteed turnaround.
3. You deliver originals to our office (or book a Bangkok pickup) and pay a 50% deposit.
4. We translate, certify, and submit to the relevant Thai authority in sequence.
5. Final documents are scanned and emailed for your review before physical dispatch.
6. We ship by EMS domestically and DHL/FedEx internationally, with tracking numbers.

Timeline & Fees

Standard turnaround: 5-7 business days from receipt of complete originals.
Rush turnaround: 1-3 business days (rush surcharge applies).
Government fees are charged at official rates with no markup.
Domestic EMS at Thailand Post rates; international DHL/FedEx at actual weight-based rates.

Common Pitfalls & How to Avoid Them

Originals out of validity window — many destinations require documents issued within 3-6 months. Confirm with the destination authority first.
Name mismatch between document and passport — embassies reject these. Correct it at the district office before translating.
Using a translator without an official seal — MFA and embassies will not accept it; you'll restart the chain.
Skipping MFA legalization before the embassy step — wastes multiple trips and weeks of time.

Common Pitfalls (From Field Experience)

Skipping district-office signature certification before MFA — MFA will reject.
Using a translator not accepted by MFA — translation must be re-done by an approved translator.
Submitting to the destination embassy before MFA legalization — the embassy will bounce it back.

Decision Tree

เอกสารเป็นทะเบียนราษฎร์ (สูติบัตร / ทะเบียนสมรส)?: Yes → ไม่ต้องผ่านอำเภอ — เข้า MFA ได้เลย (ถ้าออกโดยอำเภอเดิม); No → ต้องผ่านหน่วยงานต้นสังกัดก่อน

The MFA + destination embassy chain in Bangkok

MFA refuses documents that lack proper upstream authentication. Corporate registries need a DBD stamp within 30 days; civil-status documents need Amphur issuance; degrees need MoE or university certification; privately-signed documents need a Notarial Services Attorney from the Lawyers Council of Thailand.

Reverse Chain: foreign documents for use inside Thailand

The 7–14-day window measures from receipt of the original document to sealed delivery. MFA Standard runs 3–5 days; MFA Express runs 1–2 days; chain packs add 7–21 days depending on the destination embassy. We commit to the timeline in writing before we start.

Vienna Convention basis and international recognition

The THB 3,500–8,500 fee covers the government charge (THB 200 standard, THB 400 express, per document), upstream authentication verification (Notary / DBD / MoE / MoI), MFA counter filing, and sealed EMS/DHL delivery. Nothing is hidden — every receipt is itemised.

Name-spelling and date-format landmines to avoid

Thailand acceded to the Hague Apostille Convention in 2025, but MFA legalization is still the correct route for (a) ~70 non-Hague destinations (China, India, Saudi Arabia, UAE, Vietnam, Qatar, etc.), (b) document classes excluded under Article 1 of the Convention, and (c) destinations that specifically require dual authentication.
