Certification TiersFees & TurnaroundLanguages & Language PairsRequired DocumentsThai Government FilingsApostille 2026 & Foreign DocumentsCorporate & Business Translation
Q1.What certification does a translated document need to be accepted in Thailand?

Foreign documents need three layers: origin-country certification (an Apostille for Hague members, or origin MFA plus Royal Thai Embassy legalization for non-members), a Thai translation that mirrors the original layout, and translation certification by the Department of Consular Affairs at Chaeng Watthana. Miss any layer and the Amphur, Immigration, Land Office or DBD will refuse the filing.

Q2.How much does MFA translation certification cost?

Government legalization fees are THB 200 per stamp for the standard service (documents returned in two to three working days) and THB 400 per stamp for the same-day express service on straightforward files. Stamps are counted per page requiring certification, not per set. Translation and agency handling fees are separate from the government fee.

Q3.How long does certified translation plus legalization take?

Standard civil records translate in one working day; corporate documents and court judgments take two to three. Adding consular certification, plan for three to five working days end to end. Express handling can compress the whole chain to one or two working days when the source documents are already clean.

Q4.Why do translations get rejected most often?

Name spellings that differ from the passport, dates left in the Buddhist calendar, uncertified photocopies, registrar signatures that do not match the specimen on file, and translations that reorganize the original layout. We proof every source document against these five checks before translation begins.

Q5.Does Thailand's 2026 Apostille accession remove the need for translation?

No. An Apostille authenticates the signature and seal on the issuing document; it says nothing about language. Apostilled foreign documents still need a Thai translation certified by the Department of Consular Affairs before any Thai authority will accept them. What disappears is the second embassy stamp, saving roughly five to ten working days.

Q6.What documents do I need translated to marry a Thai national?

An Affirmation of Freedom to Marry from your embassy, your passport, and, if applicable, a divorce decree or a former spouse's death certificate. All must be translated into Thai and certified by the Department of Consular Affairs, and most district offices want them issued within the previous three months.

Q7.Do I need certified translations for a Thai work permit?

Yes. The Department of Employment requires degree certificates, transcripts and employment references in Thai or English with certification. Foreign qualifications must clear an Apostille or embassy legalization before translation, so start the paperwork four to six weeks before your intended filing date.

Q8.How are foreign corporate documents prepared for company registration in Thailand?

The parent company's Certificate of Incorporation, memorandum and board resolution must be notarized abroad, apostilled or legalized by the Royal Thai Embassy, then translated into Thai and certified at the Department of Consular Affairs. The DBD generally wants documents issued within six months, and the transliterated company name must match the name reserved in its system.

Q9.Can I use a power of attorney signed overseas for a Thai property transfer?

Only after the full chain: notarization abroad, Apostille or Thai embassy legalization, Thai translation, and consular certification of that translation. The Land Office reads powers of attorney narrowly, so list each authorized act explicitly — sign the transfer, receive proceeds, pay taxes — rather than granting a general authority.

Q10.Do you accept scanned copies, or do you need originals?

We can start translation from a clear scan, but consular certification requires the original or a copy certified by the issuing authority with a wet signature and seal. Self-certified photocopies are refused. Courier the originals to us while we prepare the draft, and you lose no time.

Q11.How long does a certified translation stay valid?

The consular stamp itself does not expire, but receiving authorities impose their own windows: typically three months for district offices and the Land Office, three to six months for embassies and the DBD. Past that you must re-issue the source document and re-certify the translation, so fix your filing date before starting.

Q12.Can you file on my behalf if I am outside Thailand?

Yes. Send the originals by tracked courier with a signed power of attorney and ID copies. We email the draft translation for your approval, file at Chaeng Watthana under the representative queue, and return the certified set by EMS or DHL — typically three to seven working days in transit depending on destination.

Q13.Are medical records handled differently?

Hospitals and insurers generally accept translator- or attorney-certified translations without consular legalization. Consular certification is needed only when the records support litigation, cross-border claims or a government filing such as a medical visa. We keep ICD-10 codes and generic drug names intact to avoid clinical ambiguity.

Q14.Once the Apostille Convention applies to Thailand, do I still need the MFA to certify my translation?

Yes. The Convention enters into force for Thailand on 28 February 2027 and only authenticates the origin of a public document — the signature, capacity and seal of the issuing officer. It says nothing about translation accuracy, so destination countries keep their own rules: some require a locally sworn translator, others accept an MFA-certified Thai translation before the apostille is issued. Confirm current status at hcch.net and consular.mfa.go.th.

Q15.What is the route for Thai documents going abroad before 28 February 2027?

The existing legalization chain applies: obtain a certified extract from the issuing registrar, translate into English or the destination language, have the translation legalised by the Legalization Division of the Department of Consular Affairs, then present it to the destination country's embassy in Thailand. Several countries — Germany is the common example — still require a second translation by a locally sworn translator, so always confirm with the receiving mission before work starts.

Q16.Which language pairs will the Thai MFA certify?

Consular legalization of translations is built around the Thai–English pair; other languages are accepted only within published limits. Where a third language is required, the reliable route is to legalise the English translation in Thailand first, then have a registered translator in the destination country translate onward from the legalised set. Check the accepted list on consular.mfa.go.th on the day you file, as it is revised periodically.

Q17.Must the translation be bound to a copy of the source document?

Always. The translation must be physically attached to the copy it was made from, and that copy must be an original or a registrar-certified extract — not a phone photograph. A loose translation page with nothing to compare against is refused at the counter.

Q18.Can legalization be filed outside Bangkok?

The main counter is at Chaeng Watthana, and some regional passport and legalization offices accept document certification, though turnaround is longer because files are forwarded to head office. Applicants outside Bangkok usually appoint a representative to file at Chaeng Watthana and have the set returned by EMS. Verify current service points at consular.mfa.go.th before travelling.

Q19.What does a representative need in order to file for me?

A power of attorney describing the scope of work, signed copies of the ID or passport of both principal and representative, and the originals to be filed. If you are abroad when you sign, have your signature certified at a Thai embassy or consulate — an uncertified foreign signature is the most common reason a representative filing is refused.

Q20.Can faded or torn documents be translated and certified?

They can be translated, but the risk of refusal is high because the officer must read the source text against the translation. The safer path is to request a fresh certified extract from the issuing body — the district registrar for civil records, the university registry for transcripts — and translate from that.

Q21.Which translations does the Land Office require from a foreign buyer?

Typically a certified translation of the passport, of marital status evidence — marriage certificate or divorce decree — and, where an attorney signs, a power of attorney whose signature has been certified and legalised. Purchases through a foreign company also need the home-country corporate certificate, fully authenticated and translated. Individual land offices apply detail differently, so confirm with the office handling the parcel.

Q22.How do I get a foreign corporate certificate accepted by the DBD?

Obtain a current extract from the home registry, authenticate it in the country of origin — apostille where the Convention applies, otherwise foreign ministry plus the Thai embassy — then translate into Thai and have the translation legalised by the Department of Consular Affairs. The DBD generally wants documents issued within six months and checks that director names match the power of attorney letter for letter.

Q23.Are medical certificates treated differently?

Hospitals and insurers usually accept a translator- or attorney-certified translation without consular legalization. That changes when the records support litigation, a cross-border claim or a medical visa. Translations keep ICD-10 codes, generic drug names, dosages and units exactly as issued; we never convert units, because that introduces clinical ambiguity.

Q24.Is a translated Thai driving licence enough to drive abroad?

Often not. Many countries require an International Driving Permit under the 1949 Geneva or 1968 Vienna Convention alongside the domestic licence. A certified translation helps when renting a vehicle or exchanging for a local licence where the transport authority says a translation is accepted. Check the destination transport authority's rules rather than relying on the translation alone.

Q25.Can I machine-translate the text and have you certify it?

We advise against it. Whoever certifies accepts responsibility for the text, and machine output on official documents typically fails on proper names, document numbers, official titles and table layout — exactly what the reviewing officer checks first. We will review and correct a client-supplied translation, but it is billed as editing and the layout must still be rebuilt to mirror the original.

Q26.Are PDF copies of certified translations accepted?

Most Thai authorities still require the paper set with a wet stamp. PDFs are useful for draft approval and for advance review by counsel or the receiving company. Some embassies and foreign universities accept translations signed electronically or sent directly from the translator's address. Ask the receiving body in writing before choosing a format.

Q27.How long does a certified translation remain usable?

The stamp itself does not expire, but receiving authorities impose windows: about three months for district offices and the Land Office, three to six months for embassies and the DBD. Beyond that, the source document must be re-issued and the translation re-certified, so set your filing date first and work backwards.

Q28.My documents are in Chinese — what has to happen before a Thai authority will accept them?

Mainland Chinese public documents need origin-country authentication first. China is now a Hague party, so obtain an Apostille from the provincial Foreign Affairs Office or the Ministry of Foreign Affairs, then have the document translated into Thai in Thailand and the translation legalised by the Department of Consular Affairs. The most common rejection cause is a pinyin spelling that differs from the passport page, so we always follow the passport and add the Chinese characters in brackets.

Q29.Do Taiwan, Hong Kong and Macau documents follow the same route as mainland China?

No. Hong Kong and Macau issue their own Apostilles through their local authorities. Taiwan sits outside the Apostille channel Thailand recognises directly, so documents are normally authenticated through the Taipei Economic and Cultural Office in Thailand or the Thailand Trade and Economic Office in Taipei before Thai translation and consular legalisation. Confirm the current practice with the receiving office before you start.

Q30.Can a Japanese koseki tohon be used for marriage registration at a Thai amphur?

Yes — it is the primary evidence of the Japanese party's marital status. In practice the Embassy of Japan in Thailand issues an affirmation of freedom to marry based on the koseki, which is then translated into Thai and legalised at the Department of Consular Affairs. Use an extract issued within the last three months and romanise kanji names exactly as they appear in the passport.

Q31.Should Korean documents be translated directly into Thai, or through English first?

Direct Korean-to-Thai translation is accepted and the Department of Consular Affairs will legalise it. Many applicants nonetheless request the English-language versions Korean registries can issue (basic certificate, family relation certificate) and translate from those, because it removes arguments about romanisation of names and place names. Either route still requires a Korean Apostille before the papers enter Thailand.

Q32.Do German documents need a vereidigter Übersetzer, or can I translate in Thailand?

It depends on direction of travel. German documents used in Thailand only need a German Apostille plus Thai translation legalised in Bangkok — no sworn German translator is required. Thai documents used in Germany usually do need a court-sworn translator in Germany, or a translation certified by the German Embassy in Bangkok. Ask the German receiving office which form it accepts before ordering the translation.

Q33.My French document already carries an Apostille — does the French Embassy in Bangkok also need to certify it?

No. The Apostille is sufficient proof of origin. What remains is the Thai translation and its legalisation at the Department of Consular Affairs. One practical caution: a birth record must be a recently issued copie intégrale, generally not older than three months, and every registration number on the certificate must appear in the Thai translation.

Q34.How are Russian documents handled for marriage or immigration filings in Thailand?

Most Russian civil-status documents can be apostilled in Russia, after which they are translated into Thai and the translation is legalised in Bangkok. The critical detail is transliteration: Cyrillic names must be rendered exactly as in the international passport, not according to an academic transliteration scheme, otherwise the amphur or Immigration will treat the applicant as a different person.

Q35.What is the route for Arabic-language documents from Saudi Arabia, the UAE or Egypt?

Several Arab states are not within an Apostille channel Thailand can use in every case. The reliable route is authentication by the origin-country Ministry of Foreign Affairs, then attestation by the Royal Thai Embassy in that country, then Thai translation and consular legalisation in Bangkok. Islamic family documents such as a marriage contract must be translated in full, including guardian and witness details, because the amphur checks those elements.

Q36.Can Myanmar documents be certified in Thailand, and what do migrant workers need?

Two situations differ. Myanmar public documents such as birth certificates or household lists need authentication by the Myanmar Ministry of Foreign Affairs and the Royal Thai Embassy in Yangon, or by the Myanmar Embassy in Bangkok under current practice. MOU labour documents such as CI/PI papers and employment contracts are more often accepted as translator-certified translations bundled with the employer's file — confirm the format with the provincial employment office first.

Q37.Do Lao and Cambodian documents follow one common procedure?

They are similar but not identical. Neither country uses the Apostille with Thailand, so documents are authenticated at the origin Ministry of Foreign Affairs and then at the Royal Thai Embassy in Vientiane or Phnom Penh, before Thai translation and consular legalisation. Cambodian names must be transliterated to match the passport, and Lao text must be fully rendered into standard Thai rather than copied across because the scripts look similar.

Q38.A Vietnamese notary office already certified my document — is that enough for Thailand?

Not on its own. Công chứng certification is domestic only. Vietnam is now a Hague party, so request an Apostille from the Ministry of Foreign Affairs or the competent provincial justice department, then translate into Thai and legalise the translation in Bangkok. The older route of attestation at the Royal Thai Embassy in Hanoi is still workable for some receiving offices.

Q39.Do Italian and Spanish filings require a traduzione giurata or traducción jurada?

Yes, when Thai documents travel to Italy or Spain: both accept only registered sworn translators or translations certified by their own embassy or consulate. In the opposite direction — Italian or Spanish documents used in Thailand — an origin Apostille plus a Thai translation legalised at the Department of Consular Affairs is sufficient. We match the format to the specific embassy's published requirement before work starts.

Q40.What should I watch out for with Dutch, Swedish, Danish, Norwegian and Finnish documents?

Northern European civil registry extracts have very short validity — often three months, sometimes as little as six weeks. Build the three to five working days needed for translation and consular legalisation into that window. Many of these extracts are issued bilingually with English, and where a bilingual version exists we translate from it to reduce name discrepancies.

Q41.Is it hard to find certified translators for Turkish or Persian in Thailand?

Turkish is straightforward: Turkey issues Apostilles and direct Turkish-to-Thai translation is accepted. Persian is a genuinely rare pair in the Thai legalisation system, so the smoothest route is to have the Embassy of Iran in Thailand issue or certify an English version first, then translate English to Thai and legalise. Expect this route to add roughly five to ten working days.

Q42.What is specific to Indian (Hindi) and Philippine (Tagalog) documents?

Indian documents require an MEA Apostille, frequently preceded by state-level SDM attestation. Philippine documents must be PSA-issued (formerly NSO) and apostilled by the DFA. Most documents from both countries are already in English, so only an English-to-Thai translation and consular legalisation are needed; only genuinely Hindi or Tagalog text is translated from the source language.

Q43.Will the Department of Consular Affairs legalise a translation that is not Thai–English?

Consular legalisation is built around the Thai–English pair. For a third-language source, the accepted approach is a translation into Thai (or English) signed and certified by the responsible translator, which is then submitted for legalisation. If the officer wants more assurance, the origin country's embassy in Thailand may be asked to certify the accuracy of the translation as an extra layer first.

Q44.How is certified translation priced in Thailand — per page or per word?

Fixed-format civil registry documents such as birth certificates, house registrations and name-change records are usually quoted per page, while contracts, pleadings and financial statements are quoted per word or per working hour because length varies. Price drivers are the language pair, urgency, the number of certification stamps required and layout work to mirror the original. Watch for quotes that omit government legalization fees and courier costs. We quote the file as a package with the stamp count shown, so the full route cost is visible before work starts.

Q45.What should be watched when translating financial statements for overseas filing?

Keep the account structure and every figure identical to the original, including the notes and the auditor's report. Never reformat numbers or convert currency; label amounts clearly as THB and keep account names consistent with the reporting framework used. Work from the stamped copy filed with DBD or the Revenue Department, translate the full set rather than the summary pages, then certify the translation. Foreign banks and registrars often reconcile against the corporate tax return, so translate that in the same batch.

Q46.Do translations for Thai Immigration follow different rules from outbound filings?

Yes — direction and certifier differ. Immigration filings translate foreign documents into Thai, and in many cases the issuing country's embassy in Thailand must legalize the document first, after which the MFA certifies the Thai translation. Outbound work runs the other way, from Thai into the destination language. Keep the Thai spelling of personal names identical to the spelling used in other Thai records such as a marriage registration or work permit, or the file will read as a different person.
