If you’re dealing with official paperwork in Thailand for international use such as getting married, applying for a long-term visa, setting up a business, or submitting documents to a foreign embassy you will almost certainly need to get your documents legalized by the Thai Ministry of Foreign Affairs (MFA).
This process, while straightforward, can be tricky due to specific requirements and potential queues. This comprehensive guide will walk you through the entire process step-by-step, outlining costs, timelines, and crucial tips to ensure you get it right the first time.
What Is MFA Legalization?
Legalization is the official process of verifying the authenticity of a signature and seal on a document, confirming that it is genuine and valid for use in another country. In Thailand, this is handled by the Legalization Division of the Department of Consular Affairs, part of the Ministry of Foreign Affairs.
Essentially, the MFA is certifying that the person who signed your document (e.g., a district officer, a school registrar, or a certified translator) holds the authority they claim.
You will typically need legalization for documents such as:
- Personal Documents: Birth certificates, marriage certificates, divorce decrees, death certificates, name change certificates.
- Educational Documents: Diplomas, degree certificates, academic transcripts.
- Official Records: Police clearance certificates, adoption papers.
- Legal & Business Documents: Power of Attorney, company registration documents, contracts, affidavits.
- Embassy-Issued Documents: Affidavits of freedom to marry, notarial acts performed at a foreign embassy in Thailand.
👉 Crucial Note on Translations: If your original document is not in Thai, it must first be translated into Thai by a certified translator. Conversely, if your Thai document is for use in a non-Thai-speaking country, it must be translated into English by a certified translator. The MFA legalizes both the original document and the certified translation but only legalizes documents in Thai and English.
The Step-by-Step Legalization Process
Follow these steps carefully to ensure a smooth process.
Step 1: Prepare Your Document Packet
Gathering the correct documents is the most critical step. Missing or incorrect paperwork will lead to rejection.
- The Original Document: You must have the original certificate or document. Exception: For some documents, a certified copy from the issuing authority (e.g., a copy of a marriage certificate certified by the Amphur/District Office) may be accepted. Always bring the original just in case.
- Certified Translation: The document must be translated by a professional, certified translator. The translator must sign every page of the translation and affix their official seal.
- Signed Photocopies:
- A photocopy of your passport (photo page) and valid Thai entry stamp.
- A photocopy of your Thai ID card or driver’s license (if applicable).
- Important: You must sign each photocopy in blue ink to certify it as a true copy.
- Power of Attorney (if using a representative): If someone else is submitting on your behalf, you must provide:
- A signed Power of Attorney (POA) form.
- A signed photocopy of your passport or ID.
- A signed photocopy of your representative’s passport or ID.
Step 2: Submit at the MFA Legalization Division
There are two main locations for in-person submission.
1. Main Office (Bangkok):
- 📍 Location: Legalization Division, 3rd Floor, Department of Consular Affairs, 123 Chaeng Wathana Road, Thung Song Hong, Lak Si, Bangkok 10210.
- Operating Hours: Monday–Friday, 08:30 – 15:30 (closed on public holidays).
- The Process: Book and appointment on the official website – https://qlegal.consular.go.th/. Ensure you complete your details correctly and fully or your appointment may be rejected. When you arrive at the MFA take a queue number from the machine, fill out the legalization application form, and wait for your number to be called. The officer will review your documents, calculate the fee, and give you a payment slip and a receipt with your collection date.
2. CentralWorld Office (Bangkok):
- 📍 Location: CentralWorld, 6th Floor, 999/9 Rama I Rd, Pathum Wan, Bangkok 10330.
- Note: This is a smaller office with potentially limited capacity. It’s best for submitting a small number of documents.
💡 Pro Tip: The Chaeng Watthana office is notoriously busy. Aim to arrive before your appointment time to get a queue number early, especially if you hope to use the express service.
Step 3: Choose Processing Time and Pay Fees
You have two options for processing speed:
- Standard Service:
- Time: 2 full business days (e.g., submit Monday morning, collect Wednesday morning).
- Cost: 200 THB per stamp/seal or 400 THB if submitting a document with a translation.
- Express Service:
- Time: Same-day collection (if submitted before 11:00) or next business day.
- Cost: 400 THB per stamp/seal or 800THB if submitting a document with a translation.
- Note: Non-Thai documents cannot be legalized with an express service.
Payment is made in cash at a separate counter after your documents have been accepted.
⚠️ Warning: The Ministry of Foreign Affairs is notorious for inconsistent proofreading of translated documents. Proofreaders do not adhere to a set standard and sometimes will choose various synonyms and request edits of translations. In these cases, you will need to submit an edited translation on the second business day and collect the legalized document on the third business day.
Step 4: Collect Your Legalized Documents
Return to the same office on the collection date printed on your receipt. You will need:
- The original receipt (this is essential).
- Your ID or passport.
Go to the collection counter, present your receipt, and you will receive your documents, which will now bear an official MFA sticker, stamp, and signature, making them legally recognized.

Common Mistakes to Avoid
- Uncertified or Poor Translations: The MFA will reject translations that are not signed and sealed by a recognized certified translator.
- Forgetting Originals: Even if you have copies, the officer will almost always ask to see the original document. Don’t leave it at home.
- Skipping a Necessary Prerequisite: For foreign documents, you must often get them certified by your country’s embassy in Bangkok before taking them to the Thai MFA for final legalization.
- Arriving Too Late: When booking a queue at the MFA, there will be a two hour window where you can submit the documents (e.g. 10:00 AM until 12:00 PM). Ensure you arrive on time to secure the queue for submission.
- Unsigned Photocopies: All copies of passports, IDs, and other supporting documents must be personally signed.
Frequently Asked Questions (FAQs)
Do I really need to get my documents legalized?
If an official body (like an embassy, a foreign government, or a Thai immigration office) requires the document for a legal process, then yes, legalization is almost always mandatory. Simple certified translations may suffice for internal business use, but not for official government purposes.
Can I submit documents by mail?
Yes, the MFA offers a postal service, but it takes significantly longer (1-2 weeks or more). You must mail all required documents along with a money order for the fees. This is best for those living far outside Bangkok who are not in a hurry.
How long is the legalization valid for?
The MFA legalization stamp itself does not expire. However, the document it is attached to might have a validity period. For example, a police clearance certificate is typically only considered valid for 3-6 months by the authority requesting it.
