Document legalisation
MFA legalisation at Chaeng Watthana and apostille under the Hague Convention, plus embassy counter-legalisation where the destination still requires it.
About us
Document legalisation, translation and visa specialists in Thailand
Every case we take starts from the same question: which authority receives this document, and what will they accept on the day? That question decides the translator, the certification, the ministry route and the timeline — and getting it wrong is why documents come back.
Why the destination decides everything
A birth certificate for a German family reunification visa, for a US immigrant petition and for an Australian partner visa are three different jobs. One needs a translator on the embassy's own list, one needs a Hague apostille, one needs a NAATI-certified translation with no legalisation at all. A provider who treats them as the same job will produce a document that is technically correct and still refused. We work backwards from the receiving authority's own published requirement, and we say so in writing before you pay.
What we do
Certified and sworn translation
Translations produced to the standard the specific receiving authority demands, not a generic certificate of accuracy.
Notarial services attorney
Signature and copy certification, affidavits, powers of attorney and identity verification for use outside Thailand.
Police clearance
Royal Thai Police criminal record certificates, with translation and legalisation for immigration use abroad.
Visa and immigration
Long-stay, work, family, retirement and investment routes, prepared as a complete evidence file.
Corporate and civil filings
Company registration, accounting, trademarks, marriage registration, permanent residence and naturalisation.
How we work
1. Tell us the destination
The country and the authority receiving the document decide every step that follows. We ask that first.
2. Document review
We check what you hold against what that authority accepts, and say what is missing before you pay.
3. Written quotation
Our fee and each government fee itemised, with a realistic turnaround rather than a best case.
4. Translation and certification
Prepared by the translator or attorney that authority recognises.
5. Government processing
Filed at the ministry, embassy or registrar, with the queue tracked on your behalf.
6. Delivery
Collected in person at a Bangkok meeting point or couriered anywhere in the world.
Frequently asked questions
Who exactly are you?
NOTARY & APOSTILLE TRANSLATION INTERPRETERS (NAATI) CO., LTD., company registration number 043556400249. We are a Thai-registered company whose work is document legalisation, certified and sworn translation, notarial services attorney certification, and the visa and immigration filings those documents feed into.
Are your notaries real notaries?
Thailand has no civil-law notary. What exists is the Notarial Services Attorney, a lawyer licensed by the Lawyers Council of Thailand under the Ministry of Justice to certify signatures, copies, affidavits and identity for use abroad. Every notarisation we issue is signed by a currently licensed attorney whose licence number appears on the certificate, which is what a receiving authority actually checks.
Do you translate into any language?
We handle the major embassy languages in house — English, Chinese, Japanese, Korean, German, French, Spanish, Italian, Russian and Arabic — and work through vetted sworn translators for the rest. What matters more than the language is who is allowed to certify it: some embassies accept only their own listed translators, and we file to that list rather than to a generic certification.
Can you handle a case if I am not in Thailand?
Usually yes. Scans start the file, originals arrive by courier, and the finished set is couriered to any address worldwide. Steps that legally require your physical signature — an affidavit, an affirmation of freedom to marry, a power of attorney — can often be executed at a Thai embassy in your country instead, and we prepare the wording for that.
How do you charge?
A written quotation before any work starts, itemising our fee and each government fee separately. Government fees are set by the ministry, not by us, and we pass them through at cost with the receipt. We do not start billable work on a verbal instruction.
What happens if a document is rejected?
If a rejection is caused by our error — a mistranslation, a missing certification page, a wrong stamp — we redo it and pay the re-submission fee. If it is caused by a rule change or a requirement the receiving authority applied on the day, we tell you plainly and quote the correction rather than absorb it silently.
Do you keep copies of my documents?
We retain the working file for the period Thai record-keeping practice requires, in case a receiving authority queries the certification later. Files are not shared with third parties beyond the government offices your case is submitted to.
Which offices do you deal with directly?
The Legalisation Division of the Department of Consular Affairs at Chaeng Watthana, the Ministry of Justice, the Royal Thai Police criminal records office, provincial amphoe registrars, the Department of Business Development, the Department of Intellectual Property, Immigration, and the embassies and consulates in Bangkok.
