Certified Translation (all languages)

Certified translation of Thai official and corporate documents into English and third languages, accepted by the Thai MFA, embassies and foreign authorities.

What makes a Thai translation 'certified' and who is allowed to certify it?

A certified translation is a translation issued with a signed certification statement from a translation agency or qualified translator confirming the text is a true and complete rendering of the original. Thailand has no single government translator register for general use, so acceptance depends on the receiving authority: the Department of Consular Affairs accepts translations submitted with the original document for legalization, embassies usually accept agency-certified translations, and some foreign authorities additionally require a sworn or NAATI translator. We confirm the receiving body's rule before translating so the document is not rejected later.

Do I need the original document or is a scan enough for translation?

A clear scan is enough to produce the translation, but the original is normally required for the legalization step that follows. The Department of Consular Affairs checks the translation against the original or a certified true copy issued by the responsible Thai authority, so if you plan to legalize, send us a high-resolution scan to start the translation and keep the original ready for submission.

How should Thai names be spelled in an English translation?

Always match the spelling printed in the passport, even when it differs from Royal Thai General System transliteration. Authorities compare the translation against the passport and treat any mismatch as a different person, which is one of the most common causes of rejection. If a name has been spelled differently on older documents, we add a spelling-variation note or arrange a name-consistency affidavit.

How long does a certified translation take and can it be rushed?

Standard civil documents such as an ID card, house registration, birth or marriage certificate are typically ready in one to two working days, while contracts, court judgments and academic transcripts take longer because of terminology checks. Same-day handling is possible for short standard documents if the scan arrives in the morning; rush handling does not shorten the separate MFA legalization queue.

Can you translate into languages other than English?

Yes — we handle 50+ language pairs including Chinese, Japanese, Korean, German, French, Spanish, Italian, Russian, Arabic and Vietnamese. Note that the Department of Consular Affairs mainly legalizes Thai–English and English–Thai pairs, so documents for non-English-speaking countries are usually translated into English, legalized, and then translated again into the destination language by a translator that the destination country recognizes.

Will a translation done abroad be accepted in Thailand?

It can be, but only after the foreign document and its translation are legalized by the Thai embassy or consulate in that country and then legalized again by the Thai Department of Consular Affairs. In practice it is often faster and cheaper to have the foreign document legalized abroad and translated into Thai here, because Thai authorities accept a locally certified Thai translation submitted together with the legalized original.

Does a certified translation expire?

The translation itself has no expiry date, but the receiving authority almost always limits how old the underlying document and its legalization stamp may be — commonly three to six months for civil-status documents such as a single-status certificate, marriage certificate or police clearance. Plan the translation and legalization close to the submission date rather than months in advance, otherwise the whole chain has to be redone.

What is the difference between a certified, notarized and sworn translation?

A certified translation carries the translator's or agency's accuracy statement; a notarized translation adds a Notarial Services Attorney certifying the identity and signature of the person who signed that statement; a sworn translation is produced by a translator formally appointed by a court or ministry in a specific country (common in Germany, France, Spain, Italy, Brazil). Thailand has no sworn-translator register, so for those countries we route the work through a translator recognised in the destination country or add MFA plus embassy legalization.

Can you translate a document that is handwritten or partly illegible?

Yes. Illegible passages are rendered as a bracketed note such as [illegible] rather than guessed, because inventing content invalidates the certification. If the unreadable part is material — a date, a name, an amount — we recommend requesting a fresh certified true copy from the issuing office first, since legalization officers routinely reject documents where key fields cannot be verified.

How are Thai dates converted in an English translation?

Buddhist Era years are converted to Common Era by subtracting 543, and the translation shows both where the original prints B.E. — for example '15 March B.E. 2565 (2022)'. Keeping both forms prevents mismatch questions when the receiving authority compares the translation with the Thai original or with a visa application form.

Do you translate company documents such as DBD certificates and financial statements?

Yes — affidavit/DBD company certificates, memorandum and articles of association, shareholder lists (Bor Or Jor 5), board resolutions, audited financial statements and tax filings are core corporate work. For banking, tender and overseas subsidiary use these are usually translated, legalized at the Department of Consular Affairs and then certified at the destination embassy, so we prepare the full set together to keep company-name spelling identical across every page.

Will the MFA reject a translation done by the applicant themselves?

Self-translations are frequently returned. The Department of Consular Affairs legalizes the signature of a recognised certifying party and checks the translation quality against the original; a self-made translation without an accountable certifier commonly fails on either formatting, terminology or omitted seals and endorsements. Using an agency that has a certification record with the department removes that risk.

What file format do I receive and is a digital copy accepted?

You receive a signed and stamped hard copy for official submission plus a PDF scan for your records. Some authorities — universities, some employers, and several online visa portals — accept the PDF, but Thai government offices, embassies and district offices require the wet-signed original, so we always issue both.

How do you handle documents with seals, stamps and marginal notes?

Every seal, stamp, watermark, signature block and marginal endorsement is described in the translation, for example '[Round seal of the Bang Rak District Office]'. Omitting them is a frequent rejection cause, because the officer verifying the document compares the layout element by element against the original.

Can you re-issue or amend a translation you produced earlier?

Yes. We keep source files, so re-issuing a fresh signed copy or correcting a passport-spelling change is quick and much cheaper than a new translation. Tell us the reference on the certification page; if the underlying Thai document was reissued we retranslate only the changed pages.

How should Thai names be spelled in a certified translation?

The spelling must match the passport exactly, letter for letter, even when the Royal Thai General System of Transcription would produce a different result. Thai authorities and foreign immigration officers compare the translation against the passport machine-readable zone, and a single differing letter is one of the most common reasons a file is returned. Where a person has used another spelling on older documents, the safe practice is to keep the passport spelling in the body of the translation and add the alternative in brackets as an aka, so both records reconcile.

Does the Department of Consular Affairs check translation quality or only signatures?

The legalization division reads the translation against the Thai original and rejects it when the content, names, dates or the official body's name are wrong, so it is a substantive check and not only a signature comparison. Frequent rejection causes are Buddhist-era dates left unconverted, district and province names transliterated inconsistently, and Thai government agencies rendered with invented English names instead of the agency's own official English title.

Do Buddhist-era dates have to be converted in the translation?

Yes — Thai documents use the Buddhist Era, and the English translation must show the Gregorian year, which is the Buddhist year minus 543. Most authorities accept the format 1 May 2024 (B.E. 2567) so the reader can trace it back to the original. Leaving 2567 in the English text makes the document look post-dated by 543 years and is routinely queried by embassies.

Can I translate my own documents if my English is good?

No — a translation submitted for legalization or to an embassy must be produced and signed by a translator who is independent of the document holder, because the certification statement is a declaration by a third party. Self-translations are refused at the Department of Consular Affairs even when the wording is perfect, and the same rule applies to translations produced by a relative or by the applicant's own company.

What is the difference between a certified, notarised and legalized translation?

A certified translation carries the translator's signed statement of accuracy; a notarised translation adds a Notarial Services Attorney certifying the signature on that statement; a legalized translation has been stamped by the Department of Consular Affairs, and often by the destination country's embassy afterwards. Which level you need is set by the receiving authority, not by the document type — a university may accept the first level, while an immigration department almost always requires the third.

How is the layout of a certified translation supposed to look?

It mirrors the original page by page, keeps the same headings and table structure, and describes rather than reproduces every non-text element — stamps, seals, handwritten signatures and security printing are shown in square brackets such as [Official seal of Bang Rak District Office]. Nothing may be silently omitted; even a struck-out line or an illegible word must appear as [illegible] so the reader can see the translation is complete.

Can you translate a document I only have as a photo on my phone?

We can prepare the translation from a clear photograph, but the legalization step requires the physical original or a copy certified by the issuing office, so a phone image alone will not carry a document through the Department of Consular Affairs. Send the photo first so drafting and name checking can start, then bring or courier the original before the legalization appointment.

Which languages can be legalized directly, and which need an English pivot?

The Department of Consular Affairs legalizes Thai-to-English and Thai-to-selected-language translations, but many embassies only accept their own language, so the common route for languages such as German, French, Spanish, Japanese, Korean and Arabic is Thai to that language directly where the embassy permits, or Thai to English plus a further translation done in the destination country. Confirming with the receiving authority first avoids paying for a chain that is then refused.

How long does a certified translation stay valid?

The translation itself does not expire, but the receiving authority usually limits how old the underlying document and its legalization stamp may be — three to six months is the common window for civil-status documents used in visa and marriage files. Academic transcripts and company documents are generally accepted for longer, but if the underlying record can change, expect the authority to require a recently issued original.

What should I check before accepting a finished translation?

Check the passport spelling of every name, the converted dates, the document number, the official English name of every issuing agency, and that each stamp on the original is described somewhere in the translation. These five items account for most rejections, and correcting them before legalization costs nothing, while correcting them afterwards means paying the legalization fee a second time.

Can a translation done abroad be used in Thailand, or must it be redone here?

A translation produced abroad is acceptable only if the destination Thai authority can verify the translator, which in practice means the translation was certified by a Thai embassy or consulate overseas. A translation certified by a local sworn translator in Germany, France or Japan is usually rejected at Thai counters unless it carries a Thai consular endorsement. If your document is already abroad, it is normally faster and cheaper to send a scan and have the Thai-side translation prepared here, then match it to the original on arrival.

Why does the Department of Consular Affairs reject translations that look correct?

Most rejections are formal rather than linguistic: a name spelled differently from the passport, a date rendered in Buddhist era where the source used Gregorian, an omitted registrar's seal line, a missing document number, or a layout that does not mirror the original block by block. The reviewing officer compares the translation against the Thai original line by line, so anything present in the source and absent in the translation is treated as an error even when the meaning is intact.

How should Thai names be transliterated so every document matches?

Use the spelling that already appears in the passport, and keep it identical across every document in the file. The Royal Thai General System of Transcription is the default when no passport spelling exists, but a passport spelling always overrides it. Where an older document carries a different romanisation, we add a translator's note linking the two spellings rather than silently harmonising them, because a silent change is what triggers questions at embassies.

What is the difference between certified, notarised and sworn translation in practice?

Certified translation is a translator or agency statement of accuracy, and is what Thai ministries and embassies normally require. Notarised translation adds a Notarial Services Attorney attesting the signature on that statement, and is used for documents going to common-law jurisdictions. Sworn translation is a civil-law concept where a court-appointed translator's own seal carries legal force, used in Spain, Italy, France, Germany and Poland. Asking which one the receiving office needs, before ordering, avoids paying for two rounds.

Do you translate documents for provinces outside Bangkok and for clients overseas?

Yes. Documents are handled by scan for clients anywhere in Thailand and abroad, and hard copies are couriered to any Thai province or shipped internationally. Legalization is still processed at the Department of Consular Affairs in Bangkok or its regional counters, so provincial clients gain nothing by travelling; the constraint is courier time, not distance. For clients in Australia, the UK, the US and the EU, we work to the destination country's requirements from the first draft.

Which file format and scan quality do you need to start work?

A flat, in-focus colour scan or photo at 300 dpi equivalent, showing all four corners, every seal and any reverse-side endorsement. PDF is ideal, JPEG or HEIC is fine. Cropped edges are the single most common cause of a re-request, because the missing strip often contains the document number or registrar signature that the translation must reproduce.

Can you translate handwritten Thai registrar entries and old records?

Yes, and this is routine for older house registration books, hand-completed marriage registers and pre-digital birth records. Where a handwritten entry is genuinely illegible, we do not guess: the translation marks it as illegible and, when the entry matters, we recommend obtaining a fresh certified extract from the district office, which reissues the record in printed form.

How are technical, medical and legal terms handled consistently across a large file?

We build a project glossary before drafting when a file exceeds a few documents, fix the rendering of party names, entity types, court terms and clinical vocabulary, and apply it across every document in the set. Consistency matters more than elegance: a reviewing officer who sees the same Thai term rendered two ways in one bundle will question both.

Do universities and immigration offices accept digital or e-signed translations?

It depends entirely on the recipient. Many overseas universities and some immigration portals accept a signed PDF uploaded directly; Thai ministries, district offices and most embassies still require wet-ink originals with the agency seal. We issue both by default so you are not blocked by a counter that refuses digital copies.

What turnaround is realistic for a standard set of civil documents?

For a typical set such as birth certificate, house registration and ID card, translation is usually ready within one to two working days. Adding MFA legalization extends the total to roughly three to five working days for the standard service and about two working days for the expedited counter, subject to queue conditions at Chaeng Watthana. Embassy steps add their own separate lead time and are the least predictable element.

What makes a translation 'certified' in Thailand when there is no sworn translator register?

Thailand has no sworn-translator register, so certification means a translation company or translator signs a certificate of accuracy on letterhead, states their credentials, and stamps every page. That package is what the Department of Consular Affairs, embassies and foreign authorities actually check. The strength of the certificate comes from the certifier being traceable and from the translation matching the source exactly, including spellings taken from the passport rather than transliterated afresh.

Why must a name in a translation match the passport spelling exactly?

Because the receiving authority matches documents by name string, not by pronunciation. A Thai name can be romanised several defensible ways, and if the translated birth certificate spells it differently from the passport, the file reads as two people. We take the passport spelling as authoritative and, where an older document already carries a different romanisation, add a translator's note recording that both refer to the same person.

Can a translation be certified if the original document is damaged or partly illegible?

Yes, but the illegible portion must be marked as such rather than guessed. Standard practice is to render the readable text and insert a bracketed note such as [illegible] at each gap. Inventing content is a defect that can void the whole file. If the gap covers a material field — a date, a registration number, a signature — the practical fix is to obtain a fresh certified extract from the issuing office before translating.

Do embassies accept translations produced outside Thailand?

It depends on the embassy and the direction of travel. For Thai documents being legalised at the Thai MFA, the translation must be produced and certified in Thailand because the MFA endorses the certifier's signature. For foreign documents used in Thailand, some embassies certify their own nationals' translations abroad and Thai authorities accept them after embassy and MFA endorsement. Confirm the chain before paying for a translation in the wrong jurisdiction.

How are Thai addresses handled in an official translation?

Addresses are transliterated rather than translated, with administrative units labelled in English — tambon rendered as sub-district, amphoe as district, changwat as province. House registration numbers and moo numbers are reproduced exactly. Translating a place name into its English meaning creates an address that does not exist in any registry, which is why receiving authorities reject it when they cross-check against the house registration.

What is the difference between a certified translation and a notarised translation?

A certified translation carries the translator's declaration of accuracy. A notarised translation adds a Notarial Services Attorney certifying the signature on that declaration — the notary attests who signed, not whether the translation is correct. Authorities that ask for notarisation want the identity link; authorities that ask for legalisation want the MFA endorsement instead. Buying the wrong layer costs time without adding acceptance.

Should company documents be translated from the DBD certified copy or from a scan?

Always from a recently issued certified copy from the Department of Business Development. Company particulars change, and authorities routinely require the underlying extract to be issued within a stated window, often three or six months. Translating an old scan produces a technically accurate translation of a stale document, which fails on currency rather than on quality.

How long should a certified translation remain valid?

The translation itself does not expire; the underlying document's currency rule does. A birth certificate is a historical fact and its translation stays usable, while a single-status certificate, a police clearance or a company extract is treated as fresh evidence and is usually accepted only within three to six months of issue. Plan the translation date to sit inside the window the receiving authority applies to the original.

Can one translation be reused for several embassies?

Often yes, provided each embassy accepts the same certifier and no embassy requires its own in-house translation. The practical approach is to order enough certified sets at the outset, because each set must carry original signatures and stamps rather than photocopies. Reprinting later means re-certification, which costs more than ordering a second set alongside the first.

What happens if the receiving authority disputes a term in the translation?

A reasoned translator's note usually resolves it. Thai legal and administrative concepts do not always have exact English equivalents — for example the various land title classes — and the accepted method is to give the closest term with the Thai original in brackets. When an authority insists on its preferred wording, the translation is amended and re-certified; the source document is never altered to match.

How should Thai names be transliterated so the translation matches every other document in the file?

Copy the spelling printed in the passport, letter for letter, and never re-romanise from the Thai script. The Royal Thai General System of Transcription produces a different result from the spelling many passports carry, so a fresh transliteration creates a mismatch that immigration officers read as two different people. Where an older document already carries a different spelling, we keep the passport spelling in the body of the translation and add a translator's note recording the variant, which is the form receiving authorities accept without a query.

Do Thai dates need to be converted from Buddhist Era to Common Era in the translation?

Yes, and the safest practice is to show both. Thai civil documents carry Buddhist Era years (CE + 543), and a translation that leaves 2568 unconverted will be read abroad as an impossible future date. We render the date as the Common Era equivalent followed by the original Buddhist Era year in brackets, which lets the receiving officer reconcile the translation against the Thai original without doing arithmetic.

What makes a translation 'certified' in Thailand when there is no sworn-translator register?

Thailand has no state register of sworn translators, so certification rests on the translation agency's or translator's signed declaration of accuracy, attached to the translation with company details and contact information. That declaration is what the Department of Consular Affairs examines when it certifies the document, and the consular certification is what foreign authorities actually rely on. For countries that require a sworn translator by law, the translation must instead be produced or re-certified by a translator sworn in that jurisdiction.

Can a translation be rejected even when every word is correct?

Yes — most rejections are formal, not linguistic. The common causes are a missing translator declaration, a layout that does not mirror the original's seals, stamps and signature blocks, an omitted marginal annotation, or a page count that does not match. We reproduce every stamp and handwritten note as a bracketed description in the same position it appears on the original, so the reviewer can map one page onto the other at a glance.

Should scanned or emailed copies be translated, or do you need the original document?

We can translate from a clear scan, but the certification chain downstream usually needs the original or a freshly issued certified copy. The Department of Consular Affairs compares the translation against an original or an office-issued copy, so a translation prepared from a photograph is fine for drafting and quotation but must be re-attached to the proper original before submission. Sending the scan first simply saves a day.

Should I translate a Thai document before or after the Ministry of Foreign Affairs legalizes it?

In the standard Thai workflow the translation is prepared first and the Department of Consular Affairs then certifies the translation together with the original. Legalizing the Thai original on its own does not make the translation acceptable abroad, because the foreign authority needs a certified link between the two documents. The one exception is when the destination country requires a sworn translator of its own jurisdiction: there the Thai original is legalized first, and the sworn translation is produced abroad from the legalized document.

How many copies of a translated document should I order?

Order at least one more certified set than the receiving authority asks for, because each certified set carries original signatures and stamps that cannot be photocopied and re-used. Embassies and immigration offices routinely retain the set they receive, so an applicant with a single set has nothing left for a second filing, an appeal, or a bank. The exact number required varies by authority, so confirm it against the current checklist published by the office you are filing with.

Can a document that is already in English still need a Thai translation?

Yes — Thai government offices generally work from Thai, so a foreign English-language document usually needs a Thai translation plus the appropriate certification before a Thai office will accept it. This applies to foreign birth, marriage and divorce records, police certificates, company documents and court orders. The reverse direction into Thai follows the same certification chain: translation, consular certification of the translation, and the foreign issuing state's own legalization or apostille beforehand.

What happens to handwritten notes, seals and illegible text in the source document?

They are reproduced as bracketed translator descriptions in the same position they occupy on the original, and anything genuinely unreadable is marked as illegible rather than guessed. Omitting a marginal note or a registrar's stamp is one of the most common reasons a translation is returned, because the reviewer compares the two pages side by side. If a stamp matters to the decision and is unreadable, the safer route is to obtain a fresh certified copy from the issuing office.

How long does a certified translation stay valid?

The translation itself does not expire, but the receiving authority usually imposes a recency rule on the underlying document — commonly a few months for civil-status extracts. In practice a translation is refused because the source extract is considered stale, not because of the translation date. Check the destination authority's stated document-age rule before ordering, and where it applies, request a freshly issued extract and translate that one.

How should Thai names be spelled in an official translation?

Use exactly the spelling that already appears in the person's passport, because the receiving authority matches the translation against the travel document, not against a transliteration standard. When a Thai house registration or ID card shows a different romanisation from the passport, the translation follows the passport and the discrepancy is noted rather than silently corrected. If a person has never held a passport, agree the spelling before work starts and reuse it across every document in the same file so the whole set stays internally consistent.

Can a translation be certified if the original document is damaged or partly illegible?

Yes, but the illegible portion must be marked as illegible in the translation instead of guessed. Certifying bodies compare the translation line by line against the source, and an invented reading is the fastest way to have a set rejected. The practical fix is to obtain a fresh certified copy from the issuing office first — district office, court, university registrar — and translate from that clean copy.

Do I need the original document or is a scan enough to start a translation?

A high-resolution scan is enough to begin translating, but the certification stage usually needs the original or an office-certified copy. That means the translation work and the appointment queue can run in parallel, which is where most of the calendar time is saved. Send scans that show all four edges, every stamp, and the reverse side, because seals on the back are part of the document.

Why do some authorities reject a translation that another authority accepted?

Because acceptance rules are set by each receiving authority, not by a single global standard. An immigration office may accept a certified agency translation while a court or a foreign registry demands a sworn or consular-certified version of the same text. Always confirm the requirement in writing with the office that will read the document, then choose the certification level to match it.

How long does a certified translation stay usable?

The translation itself does not expire, but the underlying document often does in the eyes of the receiving authority — three to six months is the common window for civil-status extracts and criminal record checks. If your filing slips past that window, you normally need a fresh extract and a fresh certification round rather than only a new translation. Plan the certification chain backwards from the filing date for this reason.

Should a document be translated before or after it is legalised?

Translate after the Thai-language original has been signed and sealed, but before consular legalisation, because the Department of Consular Affairs legalises the translation together with the source document. Doing it in the other order means the seal added later is not covered by the certified text and the receiving office sees an incomplete set. The only exception is a document issued abroad that must first be legalised in its own country; that one arrives already sealed and is translated afterwards.

How many copies of a certified translation should I order?

Order at least two certified sets: one to submit and one to keep, because most authorities retain the copy you hand in. Applicants who file with an embassy, a university and an employer in the same year usually need three. Ordering extra sets at the time of translation is far cheaper than re-certifying months later, since the translation work itself is already done.

Does a certified translation expire?

The translation itself has no expiry date, but the underlying document often does, and receiving offices judge the set by the age of the source. Police clearance certificates, bank statements and marital-status records are commonly required to be no older than three or six months. A birth certificate translation, by contrast, stays usable for years because the facts it records do not change.

Can one translation cover a document written in two languages?

Yes — a bilingual source is translated in full, including the portion already in English, so the target text mirrors the entire page. Skipping the English half is a common cause of rejection because the certifying statement then does not match the document as issued. Stamps, marginal notes and reference numbers printed in either language are transcribed too.

What is the difference between a certified, a sworn and a notarised translation?

A certified translation carries the translator's or agency's signed accuracy statement; a sworn translation is produced by a translator registered with a specific country's court system; a notarised translation adds an attorney's certification of the signature on that statement. Thailand has no sworn-translator register, so Thai documents for countries that expect one are usually handled with a certified translation plus notarial and consular certification. Ask the receiving office which of the three it requires before ordering.

What happens if the receiving office rejects a certified translation?

Send us the rejection note and we correct and re-issue the certified set, because almost every rejection names a specific defect rather than a general quality problem. The three recurring causes are a name spelled differently from the passport, a missing page such as the reverse side of a registrar's form, and a translation certified before the original was sealed. Each is fixable without redoing the whole document set.

How should Thai names be spelled in a translation when documents disagree?

The passport spelling governs, and any other spelling appearing on a Thai record is carried into the translation with a translator's note explaining the variance. Thai romanisation is not standardised, so a house registration, a degree certificate and a passport can legitimately show three spellings of one name. A note that links them prevents an officer from treating the documents as belonging to different people.

Can you translate a document that is partly handwritten or faint?

Yes, provided the text is legible enough to read with confidence; anything genuinely unreadable is marked [illegible] rather than guessed. Old handwritten house registrations and hospital records are routine work for us. Where a stamp or signature cannot be deciphered, the certified translation describes its position and content type, which is what registrars expect to see.

Do you translate into languages other than English?

Yes — we work across roughly 48 languages, with the highest volume in Chinese, Japanese, Korean, German, French, Spanish, Italian and Arabic. For countries that require a sworn or court-appointed translator, we route the file to a translator holding that appointment rather than issuing an ordinary certification. Tell us the destination authority first, because that decides which form of certification is valid.

Is a scan of a certified translation acceptable, or must it be the paper original?

It depends entirely on the receiving office: most online visa portals accept a colour scan, while registrars, courts and consular counters almost always demand the sealed paper set. We deliver both — a PDF for immediate upload and the physical copies by courier or in person. Keep the paper set intact; removing a staple from a sealed bundle can invalidate the certification.

Why use a translation firm that also advises, rather than a pure translation shop?

Because the translation is rarely the last step — what decides acceptance is the certification layer that follows it. A file may need company certification only, or MFA legalization at Chaeng Watthana, or a further embassy stamp, and each route dictates a different original document. Our team has mapped these routes for more than fifteen years, so we tell you the whole chain before the first page is typed instead of after a rejection.

Can I translate the document myself and just pay you to certify it?

Only where the draft is genuinely accurate, and it usually saves less than people expect. Certification makes us legally answerable for every line, so we compare the draft against the original word by word; when the error density is high the review costs about as much as a fresh translation. Having us translate from the start also lets us stand behind free corrections if the receiving office queries anything.

What hidden costs do people forget when budgeting a translation project?

Fresh certified copies from the issuing Thai office, MFA legalization fees charged per stamp rather than per document, destination-embassy fees, international courier, and the largest one — the opportunity cost of a missed filing deadline when a set is bounced. We quote the full route cost up front, including the fees we do not collect ourselves, so nothing appears halfway through.

How is machine translation with human review different from certified translation?

The difference is legal accountability, not fluency. A certified translation carries a named signatory the receiving authority can trace and challenge; machine output has nobody standing behind it and typically fails on proper names, document numbers and legal terminology. We use terminology tools for consistency, but a human translator and a second human reviewer always sign.

What exactly do I need to send before you can start a certified translation?

A clear colour scan of every page of the original, including blank reverse sides that carry a stamp, plus the spelling of every personal name exactly as it appears in the passport of the person concerned. Tell us the receiving country and office as well: an Australian department, a Thai ministry and a European consulate each expect a different certification wrapper on the same translated text. With that in hand we can confirm scope and turnaround the same working day.

What are the steps from my scan to a document the authority will accept?

Four stages. First we map the acceptance route and tell you which original the office will demand. Second a human translator produces the text and a second reviewer checks names, numbers and legal terms against the source. Third we issue the certification page with translator details and company seal. Fourth, where the route requires it, we walk the set through MFA legalization and any embassy stamp, then courier it to you or to the office directly.

What most often causes a translated set to be rejected?

Name spellings that differ from the passport, a household registration or certificate that is too old for the office's freshness rule, a photocopy submitted where a certified copy from the issuing district office is required, and missing pages such as an unstamped reverse side. Every one of these is preventable at the checklist stage, which is why we review the source set before translating rather than after.

I live abroad. Can the whole job run without me being in Thailand?

Yes, and a large share of our work is exactly that. You send scans, we confirm the route, and where a fresh Thai original is needed we can arrange retrieval from the issuing office under a signed authorization. Certification, legalization and courier all happen here; you receive the finished set at your overseas address, usually with a scanned preview first so you can check spellings before anything is sealed.

Can I translate the document myself and just have it certified?

Yes, but the certifying party must review the full text before signing, because the signatory takes responsibility for accuracy toward the receiving authority. In practice, self-translated files usually need corrections to personal-name transliteration (it must match the passport exactly), date format, and the official English names of Thai agencies — which takes about as long as translating from scratch. Ask for both quotes before deciding. If the file will later go to the Department of Consular Affairs, having one team handle translation and legalization reduces the risk of rejection.

What is the difference between an agency-certified translation and one legalized by the MFA?

An agency-certified translation is a statement by the translator and the authorised signatory that the translation matches the original; many domestic institutions accept it as is. MFA legalization at the Department of Consular Affairs is a second layer applied by a government body, and it is what foreign embassies normally require before they add their own stamp. Check what the receiving authority asks for in writing first — paying for legalization you do not need wastes both fees and days, and discovering you needed it after submission restarts the queue.

Is a cheaper per-page quote actually cheaper?

Not always, because per-page pricing hides how the page is counted and what is excluded. Compare on four points: how a page is defined (character count or physical sheet), whether proofreading by a second linguist is included, whether re-typesetting of tables, seals and stamps is included, and whether free revision is offered if the receiving authority asks for wording changes. A file that bounces once typically costs more in lost days than the price gap. We quote the full scope in writing before starting so the comparison is like for like.

What exactly do I need to send before a certified translation can start?

Send a clear colour scan of the complete original document including every seal, stamp and back page, plus the passport page of every person named in it so names are transliterated exactly as the passport spells them. If the file will go to an embassy afterwards, also tell us the destination country and the purpose, because some embassies require the translation to follow their own wording. Photos taken at an angle, cropped edges and missing back pages are the three most common reasons we have to ask for a resend, which costs a day.

In what order should translation, certification and embassy steps be done?

The correct order is: obtain a current official copy of the Thai original, translate it, have the translation certified, submit to the Department of Consular Affairs for legalization, then submit to the destination embassy. Doing the embassy step before MFA legalization is always rejected, and translating from an expired or unofficial copy means the whole chain has to be redone. Confirm in writing what the receiving authority needs before you start, because the order cannot be shortened once a stamp is on the page.

Why do translations get bounced most often?

The four recurring causes are name spelling that does not match the passport, a Thai official agency name translated freely instead of using its published English name, missing translation of seals and marginal notes, and a source copy that is older than the validity window the receiving authority accepts. All four are avoidable at intake, which is why we check the passport spelling and the source copy date before a translator begins. If you would rather not manage these checks, hand us the whole chain and we run it end to end.
