Adverse event narratives
AE narratives keep the investigator's verbatim term in Thai, then MedDRA-preferred term in English in square brackets. Regulators need both — the source term for causality, the coded term for tabulation.
Medical records, discharge summaries, lab and imaging reports, informed consent, clinical study reports, IFU / package inserts, and journal manuscripts — translated by trained medical linguists under an ISO 17100 (Translate + Edit + Proofread) workflow with ICD-10, SNOMED CT, and MedDRA termbases. HIPAA-aware handling and PDPA compliance across the pipeline.
Four steps: (1) request a hospital-stamped copy from the medical-records department, (2) certified translation by a medical linguist, (3) MFA authentication if the destination requires it, and (4) forward to the receiving hospital's international patient department. For second-opinion consults a certified translation alone is usually sufficient. Turnaround 3–7 business days.
Every project is under NDA; files sit on AES-256 encrypted storage with role-based access; working copies are purged per retention policy (default 90 days, configurable). Practice aligns with HIPAA (US) and PDPA (TH).
Yes — ISO 17100 (Translate → Bilingual Edit → Native-speaker Proofread) plus an optional native scientific editor pass. Target venues include The Lancet, NEJM, JAMA, BMJ, JCO. From THB 1.5/word (EN) or THB 2.0/word (JA/ZH).
An independent second translator renders the target text back into the source language. It is required for ICF, PRO, and COA in multi-country clinical trials per ICH-GCP, with a reconciliation step against the original.
A standard bundle (progress notes + labs + imaging ≤ 30 pages) takes 3–5 business days at THB 6,000–15,000 depending on language. Most receiving hospitals (Mount Elizabeth, NUH, St. Luke's Tokyo, Bumrungrad Referral) accept certified translation directly without MFA.
Yes — IFU / Package Insert / eLabeling per Thai FDA, US FDA 21 CFR 801, EU MDR 2017/745, and PMDA, including ISO 15223-1 symbols and typesetting to the regulator's template.
Yes — ISPOR workflow: dual forward translation → reconciliation → back-translation → cognitive debriefing (5–8 native speakers) → final report. 4–8 weeks per language, suited to multinational Phase III trials.
Free consultation. We confirm requirements with the destination authority before quoting.
We route each file to the right credential: NAATI for Australia, Ministry of Justice registered translators for Thai court work, and embassy sworn translators for European destinations. One coordinator owns the matter end to end and reports progress by LINE or email at the intervals you set. Talk to the NYC Legal team on any business day — you get a working plan, not a generic price list. Keep a digital copy of the finished certified set so it can be referenced if the destination asks for additional documents or a re-filing. Caution: government fees follow the authority's published rate and are separate from professional fees; check the current rate on the official website first. Fix three facts before any work starts: the destination country, the exact authority the file goes to, and the language that authority requires. Those three decide the whole certification chain. Caution: processing time depends on each authority's queue, so allow buffer before the date the document is actually needed. Send scans of every page for review before sending originals; that is when faded seals, passport-spelling mismatches and expired documents can still be corrected.

We route each file to the right credential: NAATI for Australia, Ministry of Justice registered translators for Thai court work, and embassy sworn translators for European destinations. Processing time depends on each authority's queue, so the working order and the expected return date are confirmed before any work begins. Tell us where the document will be used and you will get a plan and a price the same business day. The workable order is: check that the source document is complete and legible, translate it, certify the translation, file for legalisation with the Department of Consular Affairs, then obtain the destination embassy's certification — or an Apostille where the destination is a convention party. Caution: each certification covers only what its own stamp states; it does not make a document automatically acceptable everywhere. Confirm the receiving authority's conditions case by case. Keep a digital copy of the finished certified set so it can be referenced if the destination asks for additional documents or a re-filing. Caution: never unbind, trim or separate pages after an authority has sealed the set — doing so voids the certification.

A decision guide grounded in the agencies' own rules
Searching for “แนะนำแปลเอกสารขอ BOI ชาวต่างชาติ ขอนแก่น” should not be decided by search ranking. Decide on the provider can carry the file to the end of the chain and a delivery date they will actually commit to. Ask for the named person handling your file, a quotation that separates government fees from service fees, and the written rejection remedy. Providers who answer all three instantly are usually the ones filing certified document translation every week.
Start from the receiving authority, not the provider. Establish who will receive the document and what their rule is, then filter providers on "The provider can carry the file to the end of the chain". Translation is rarely the last step — consular endorsement, embassy attestation, or notarisation usually follows. One provider across the chain means fewer handovers and fewer transcription errors.
The clearest one is: Pushes for full payment before the scope is confirmed in writing. Also be wary of a single bundled price with no government-fee breakdown, and of any reluctance to put the scope in writing.
Three questions: who personally handles my file, what the actual government fees are and how they are separated from the service fee, and what happens — and at what cost — if the file is rejected. Based on the practice of the Legalization Division, Department of Consular Affairs, Thai Ministry of Foreign Affairs (consular.mfa.go.th), and NAATI standards for documents used in Australia.
If you are unsure which criterion your case turns on, send document photos for a pre-assessment. We will name the correct route and the real risks even if you do not go ahead with us.

ICH-GCP & CTD module map
Thai medical documents entering FDA, EMA, or PMDA workflows are read against the ICH Common Technical Document. If Module 1 administrative documents, Module 2 summaries, or Module 3 quality data land under the wrong caption, the sponsor loses days on validation. Our medical-translation workflow tags every document to its CTD module before delivery.
| Thai document | CTD module | Regulatory hook |
|---|---|---|
| หนังสือรับรองการขึ้นทะเบียนยา (Product licence) | Module 1.2 — Administrative | Thai FDA licence number verified against fda.moph.go.th. |
| รายงานการศึกษาทางคลินิก (Clinical study report) | Module 5.3 — Clinical study reports | ICH E3 headings preserved; adverse-event narratives translated verbatim. |
| ข้อกำหนดคุณภาพและวิธีวิเคราะห์ (Specifications) | Module 3.2.S / 3.2.P — Quality | USP / Ph.Eur monograph references retained; no substitutions. |
| ใบรับรอง GMP | Module 1.4 — Information about the manufacturer | PIC/S GMP scope preserved; audit date translated in ISO-8601. |
| เอกสารความยินยอมอาสาสมัคร (ICF) | Module 1.14 / site file | ICH-GCP E6(R2) 4.8 clauses translated per section without paraphrase. |
AE narratives keep the investigator's verbatim term in Thai, then MedDRA-preferred term in English in square brackets. Regulators need both — the source term for causality, the coded term for tabulation.
Every GMP annex reference is retained (Annex 1 sterile, Annex 11 computerised systems). We never collapse annex numbers into prose — inspectors search by annex.
ICF is translated section-by-section against ICH-GCP E6(R2) 4.8.10 (a–t). Missing sub-clauses are flagged in a translator's note rather than silently omitted.
Medical documents tagged to the correct CTD module clear validation in one pass. Untagged translations force the sponsor to re-file — expensive when the reference product is on a clock.
Clinical translations are reviewed by life-science specialists to keep ICD codes and drug names exact. Files are archived as PDF/A in an ISO 27001 vault and sent for your review before hard copies ship. Quoted prices cover every agreed step — no hidden charges. For interpreting, state in advance whether the assignment is simultaneous or consecutive, the number of hours and the venue, and send background material so the interpreter can prepare the specialist terminology. Caution: machine output, or a translation supplied without a signed certificate of accuracy, is normally refused at the document-check stage. Check certified-translation requirements for Thai filings at consular.mfa.go.th, and verify a NAATI practitioner's credential at naati.com.au. Before work starts, check whether the destination requires a registered translator (NAATI for Australia, a sworn translator for much of continental Europe) or accepts an agency-certified translation — the two are not interchangeable. In practice you send high-resolution colour scans of every page, name the destination country and authority, and confirm the passport spelling of all personal names; the translator then issues the translation with a certificate of accuracy attached.

All legal work is covered by NDA and stored in an encrypted vault with strict access control. Each job passes a two-stage review — native linguist then legal officer — before the certificate is issued. If the receiving authority rejects our translation, we correct and refile free within 30 days. Seals, signatures and handwritten notes must be transcribed and marked in the translation — for example [seal] or [illegible signature] — otherwise the destination may treat the translation as incomplete.

India is an Apostille (HCCH) member, so an Apostille replaces embassy attestation.

Translation of civil, corporate and legal documents with a certificate of accuracy, formatted to clear the receiving officer's check on the first submission.
Not sure which route your case belongs to? Tell us the destination and the deadline — our advisers have handled these files for more than 15 years and will confirm the correct sequence and exact documents before you spend anything.
A standard certified translation takes 1–3 business days depending on page count and language pair, and must be produced from the document version the destination accepts.
Prefer not to handle the queues, forms and re-submissions yourself? Our team has run these files for more than 15 years — we advise on the right route first, then complete every step for you end to end. Message us and we will confirm the exact documents for your case.
The destination country decides whether a file ends at an Apostille or still needs the embassy. Confirm the country's convention status first: the two routes use a different order and different paperwork.
| Aspect | Apostille route | Embassy legalisation route |
|---|---|---|
| When it applies | Destination is a party to the Apostille Convention | Destination does not accept an Apostille |
| Final authority | Department of Consular Affairs, Ministry of Foreign Affairs | The destination country's embassy or consulate in Thailand |
| Typical number of steps | Fewer — the chain ends at the central authority | More — central authority first, then the embassy |
| Approximate timeframe | Shorter, still subject to the authority's queue | Longer, because the embassy appointment queue is added |
| Common rejection cause | Translation does not match the original, or the copy was not issued by the authority | The embassy's own form or language requirement was not followed |
Verify the current convention status and embassy conditions before filing.
"Certified translation" does not mean the same thing everywhere. The receiving body defines the accepted form, and choosing the wrong one means translating the whole set again.
| Aspect | Translation + Thai MFA certification | NAATI / foreign sworn translator |
|---|---|---|
| Who certifies | The Department of Consular Affairs certifies the translation and the translator's signature | A translator registered with the destination country's body |
| Accepted by | Thai authorities and destinations that accept Thai certification | Bodies that explicitly require a registered translator, such as Australian immigration |
| Output format | A certification stamp on the translation attached to the original | The translator's statement with their registration number or stamp |
| Can an Apostille follow? | Yes, when the destination is a convention party | Depends on that country's rules; some require no further step |
| Check before you start | Whether the destination accepts Thai consular certification | Whether the receiving body requires its own registered translator |
Where the destination requires a court-registered sworn translator, Thai certification cannot substitute for it.
Every step can be done alone. This table compares the real workload of each option so the decision rests on time and rejection risk rather than marketing claims.
| Aspect | Do it yourself | NYC handles it |
|---|---|---|
| Checking destination rules | Read each authority's notice yourself and confirm by phone | Checked before you start, with the order the receiving authority accepts |
| Travel | Several agencies with queues that rarely line up in one day | Documents move by courier or online except where the law requires you in person |
| Rejection risk | One mismatch — a name spelled differently from the passport — restarts the chain | Names, dates and stamps are cross-checked before every filing |

Rejected translations usually fail on certification format, name spelling, or inconsistency inside the same document set.
1. Name spelled differently from the passport
Why it matters: Receivers match the name against the passport first.
How to avoid it: Send the passport bio page with every translation request.
2. Non-official renderings of institution or degree names
Why it matters: Most institutions already publish an official English name.
How to avoid it: Follow the issuing body's official English wording and keep the Thai name alongside.
3. Translating from a file where seals or signatures are unreadable
Why it matters: Seal text must be transcribed; "illegible" markers are refused by some receivers.
How to avoid it: Provide a high-resolution colour scan of the original.
4. Not knowing which certification level the receiver wants
Why it matters: Requirements range from translator certification to consular legalisation.
How to avoid it: Confirm the receiver's requirement before work starts.
5. Partial translation (missing back pages or footnotes)
Why it matters: Official documents must be translated in full, including reverse-side stamps.
How to avoid it: Scan every page, front and back, even seemingly blank ones.

Almost every failure in certified document translation happens during preparation, not at the counter, and the real cost is the TIME needed to repeat the chain. Below is what each mistake comes from, how long it typically adds, and how to avoid it.
| Mistake | Why it happens | Time cost | How to prevent it |
|---|---|---|---|
| Removing staples or separating pages after certification | The certification is attached to the bound set; once separated the set counts as incomplete. | Typically adds 3–7 working days to re-certify the set. | Scan first, then keep the originals in a rigid envelope without detaching anything. |
| The name in the translation does not match the passport spelling | Receiving authorities compare character by character; a single different letter reads as a different person. | Typically adds 3–10 working days, because the translation has to be redone and the whole chain repeated. | Send the passport page on day one and have the translator take the spelling from the passport, never from the Thai document. |
| Using an old copy instead of a freshly issued one | Many destinations accept documents issued within the last 3–6 months only, and some require a clean, legibly sealed reissue. | Typically adds 5–15 working days for the trip back to the district registrar. | Check the destination's freshness rule first, then request several certified copies in a single visit. |
| Planning without allowing for public and embassy holidays | Embassies close on both Thai and home-country holidays, so the real calendar is shorter than it looks. | Typically adds 3–9 working days around a long holiday period. | Check the holiday calendar of every body involved before fixing a travel or filing date. |
| Booking the wrong service channel or appointment type | Each channel has its own queue and document conditions; the wrong one means booking again. | Typically adds 2–14 working days depending on appointment availability that month. | Confirm the service type and the appointment date in advance and keep at least one spare week. |
The windows below are approximate and depend on each authority's queue. Stages marked as parallel can start alongside the previous stage — that is where the total calendar time is actually reduced.
We count pages, check seal legibility, and confirm which translation format the destination accepts.
A reviewer checks names, dates, figures, and terminology against the source line by line.
You approve the draft spelling against your passport before the final is issued — the single biggest source of rework.
The certificate is attached and bound to the original or the copy, as the destination requires.
Note: all windows are general estimates, not guarantees. Actual timing depends on how complete your file is and on the queues at the authorities involved.
These are the terms clients most often misread — and a leading cause of rejected documents. Our advisors walk you through them before any work starts.

Not sure which of these your case actually needs? That is exactly what our advisory team does: with 15+ years on cross-border documents, we map the full chain for your destination first, then handle every step so nothing is filed in the wrong order.
Our team has worked on documents, translation and legalisation for more than 15 years, combining notarial attorneys licensed by the Lawyers Council of Thailand with translators the receiving authorities accept. Every case starts with advice on the correct route and only then moves to execution — we do not simply run whatever is handed to us.
We confirm whether your file ends at an Apostille or still needs the embassy, whether a freshly issued copy is required, and which form of translation the receiving authority accepts. This is where most time is saved, because it is where most people choose wrongly and restart.
We match the spelling of your name against the passport, check the issue date against the validity window the destination applies, verify stamps and signatures, and confirm the translation matches the original line by line.
We file in the order each authority expects, follow the queue, and report status as it moves. If an authority asks for more paperwork, you hear about it immediately, together with the options for fixing it.
We explain which bodies this set can be filed with, how to store the originals, and how many certified sets to request up front if you expect to use them again, so you do not repeat the whole chain later.
If you are unsure which route your case takes, send photos of the documents and name the destination country or authority. We map the sequence and the paperwork first; you then decide whether to run it yourself or hand it over.
Verifies names, dates, document numbers and destination-authority wording. We are not only a filing agency — every case starts with a consultation so you know the correct route, the exact documents and the realistic timeline before any fee is paid.
Procedures and authority requirements can change. We re-check each page against the responsible authority's current practice; if your case is time-critical, message us to confirm the latest requirement.
