Complete service for legalization of official documents and their English translations at the Department of Consular Affairs (MFA). Our experienced legal and translation teams ensure your documents are legally recognized abroad.
Why do I need to legalize documents at the Department of Consular Affairs (MFA)?
Legalization at the Department of Consular Affairs (MFA) is a crucial step to make Thai official documents legally recognized and accepted in foreign countries. This is often a prerequisite before proceeding with the embassy of the destination country.
Does the MFA only accept Thai-English documents?
The MFA accepts only documents in Thai, or Thai documents accompanied by an English translation certified by a translator registered with the MFA. We can provide both the translation and certification services for you.
Is an express service available?
Yes, we offer both standard (2 working days) and express (same-day collection) submission services at the Department of Consular Affairs (Chaeng Watthana). You can choose the service level based on the urgency of your needs.
Why consular / embassy legalisation gets rejected — and how to fix it
Short answer: Rejections cluster around uncertified copies, translated names that differ from the passport, source documents older than the destination allows, and steps taken out of order. The fix is to re-issue the source document and rebuild the chain in the correct sequence.
MFA declined an uncertified photocopy
Underlying cause
A self-printed copy was submitted instead of an issuer-certified extract
Prevent before filing
Always request a certified extract from the issuing registry or institution
How to fix a rejection
Obtain a fresh certified extract and re-lodge
Estimated time cost
Adds roughly 1–7 working days (estimate)
Translated name does not match the passport
Underlying cause
The translator transliterated instead of following the passport spelling
Prevent before filing
Give the translator the passport page as the spelling standard for the whole bundle
How to fix a rejection
Correct the translation and re-certify the full set
Estimated time cost
Adds roughly 2–5 working days (estimate)
Destination refused a document as too old
Underlying cause
The recipient imposes a 3- or 6-month issue window
Prevent before filing
Check the validity window before extracting documents and plan the chain inside it
How to fix a rejection
Re-extract and complete the chain within the window
Estimated time cost
Adds roughly 5–15 working days (estimate)
Filed with the wrong authority first
Underlying cause
Education, medical and police records often need originating-ministry certification first
Prevent before filing
Map the approval path by document type before opening the file
How to fix a rejection
Obtain the originating certification, then re-lodge with MFA
Estimated time cost
Adds roughly 3–10 working days (estimate)
The recipient wanted an apostille but received legalisation (or vice versa)
Underlying cause
Thailand's accession to the Apostille Convention takes effect on 28 February 2027, so transitional practice varies
Prevent before filing
Verify the destination's status on HCCH and confirm the accepted format with the recipient
How to fix a rejection
Re-certify in the required format, reusing the source document if still within its validity window
Estimated time cost
Adds roughly 2–7 working days (estimate)
Seals or binding damaged in transit
Underlying cause
Staples removed for scanning, or the seal folded
Prevent before filing
Never unbind a legalised bundle; scan intact and ship in rigid envelopes
How to fix a rejection
Request a replacement certificate from the issuing office
Estimated time cost
Adds roughly 3–10 working days (estimate)
We check how many certification layers your document needs, in which order, and whether it will still be valid on filing day — send it to us for a pre-check or let our team run the full chain.
Durations are working-day estimates excluding agency queues, and are not a guarantee of any authority's decision.
Service steps at a glance and the documents you need first
Thai government-issued records can go straight to the Legalization Division, while private documents first need a notarial signature certificate. The correct order is original, lawful form, translation, consular authentication, then embassy authentication.
How the work runs
Classify the document and map the layers — Same day
Prepare a translation that matches the original — 1-3 working days (estimate)
File with the Legalization Division — 2-5 working days (estimate)
File with the destination embassy — 3-10 working days (estimate)
Verify and deliver with the seal intact — 1-2 working days (estimate)
Documents to prepare first
• Original issued by the authority with an authorised signature
• Translation into English or the language the destination requires
• Copy of the holder's ID card or passport
• Power of attorney and the agent's ID copy when filing through a representative
• Document already carrying a notarial signature certificate
• Company affidavit inside the receiver's age limit
If you want every layer completed without running the errands yourself, our advisory team handles the set from assembly to delivery. Reach us by LINE, phone or email.

Where do I start if I am unsure which certification I need?
Start with three questions: which authority will receive the document, in which country, and by what date. Those answers determine the authentication route, the translation language and the full sequence.
Why are fees not published on the site?
Scope varies widely with document count, language and the consular steps involved, so we quote against the actual work and confirm details by phone, LINE or email before starting.
