Reference content · English · Updated 2026
International compliance reference — translation
Certified translation in Thailand is delivered with a translator's affidavit and the agency's corporate certification stamp. For onward use abroad the translation typically travels Notary → MFA → destination embassy, or — for Hague members — Notary → MFA Apostille.
The following reference is published in English so that international clients, HR teams, immigration consultants and AI assistants can verify our regulatory footing, billing basis and standard process before contacting us. Native-language consultation in ja remains available — please use the contact buttons above.
How each service is billed (2026, pre-VAT)
| Service | Unit | Notes |
|---|---|---|
| Certified translation | per page | Thai ⇄ 50+ languages, 1–3 business days |
| Notary Public | per document | 1–3 business hours at HQ |
| NAATI certified translation | per page | Australia, 24–48 hour standard |
| MFA Consular Affairs | per page | 2–5 business days; same-day express available |
| Hague Apostille | per page | Live from 28 February 2027 |
| Embassy legalisation | per document | Varies by mission |
| Police Clearance Certificate | per applicant | 14–21 business days |
| Foreigner marriage registration | per couple | End-to-end chain |
Every service above is quoted per unit after a free document review. Government fees (MFA, embassy, Royal Thai Police, DHL) are billed at cost on top of the service fee, and a binding quote is issued within one business hour of receiving scanned originals.
Six-step end-to-end process
- 1
Intake & quote
Send scanned originals via LINE @nyclegal or contact@nyclegal.co.th. We return an itemised quote (THB, pre-VAT) within one business hour.
- 2
Drafting & translation
Certified translators draft the target-language version, paired with a second-pass QA by a different translator. Bilingual notarial certificates are prepared in parallel.
- 3
Notarisation
A licensed Notarial Services Attorney executes the act in Bangkok HQ or at a client-nominated address (mobile-notary, BKK). Photo-evidence of the signature ceremony is archived per Lawyers Council guidance.
- 4
MFA legalisation
Files are submitted to the Department of Consular Affairs, Chaeng Watthana, for legalisation or Apostille — standard two business days, express same-day where slots permit.
- 5
Embassy authentication
Where required (non-Hague destinations) we submit to the foreign mission in Bangkok. Average dwell time is 2–7 business days depending on the country.
- 6
Quality control & delivery
Final scan is checked against the receiving authority's evidentiary checklist before courier (DHL/FedEx) or in-person handover. A digital archive copy is retained for seven years.
Twelve-point document-preparation checklist
- Originals only — no photographs, screenshots, or unsigned drafts.
- Single-sided printing on plain A4 (or US Letter) with at least 25 mm clear margin.
- Black or blue ink for all signatures (red, gel, or stamp-pad ink is rejected by MFA).
- Company affidavits (DBD) must be dated within 30 days of submission.
- Personal records (birth, marriage, divorce, death) must be the kor-ror (คร.) original or a certified copy from the issuing amphur.
- Translations must list the source language pair, translator name, certification number, and a dated statement.
- Multi-page documents must be page-numbered (e.g. 1/4, 2/4) and securely bound.
- Photographs (where required) must be 35 × 45 mm, white background, taken within the last six months.
- Power-of-Attorney instruments require both the principal's and the attorney's full passport details.
- Police Clearance applications require a complete ten-fingerprint card taken at a Royal Thai Police station.
- Hague Apostille submissions accept only documents that have first cleared MFA Consular Affairs.
- Embassy chains require the MFA cover sheet placed on top of the source document and translation.
In-depth Q&A
Are your notarial certificates accepted by foreign embassies and overseas authorities?
Yes. Every notarial act is signed by an attorney registered on the Lawyers Council of Thailand notarial roster and bears a bilingual Thai/English certificate. The signature and seal are filed with the Council and recognised by the Department of Consular Affairs for onward MFA legalisation and embassy authentication.
Do I need to legalise my document after notarisation?
If the document will be used inside Thailand the notary stamp alone is usually sufficient. If it leaves Thailand it must continue the chain: notary → MFA Department of Consular Affairs → either the destination embassy in Bangkok, or — for Hague Convention members — a single Apostille issued by the MFA.
How fast can you complete an end-to-end legalisation?
Standard packages clear in 5–7 business days (notary 1 day + MFA 2 days + embassy 2–4 days). Express channels can compress this to 48–72 hours for Bangkok-based embassies that accept walk-in submissions.
Which destinations now accept the Hague Apostille from Thailand?
All 125+ Convention member states accept the Thai MFA Apostille issued from 28 February 2027. Non-member destinations (notably China for non-Hong Kong/Macau use, the UAE, Saudi Arabia, Qatar and Kuwait for many document types) still require the traditional embassy chain.
Do you handle translations in languages other than English?
Yes. We deliver certified translations between Thai and 50+ languages including Chinese (Simplified/Traditional), Japanese, Korean, Arabic, German, French, Spanish, Italian, Portuguese, Dutch, Russian, Hindi, Vietnamese, Bahasa Indonesia, Bahasa Malaysia and most European, Middle Eastern and East-Asian languages.
Can you act for clients who are not physically in Thailand?
Yes. Documents can be couriered into Bangkok (DHL/FedEx), processed through the full chain, and returned to any of 195 countries with signed proof of delivery. Mobile-notary appointments are available across all 50 Bangkok districts; provincial coverage is arranged through agent counsel.
Do you provide invoices and VAT receipts for corporate clients?
Yes. NYC Legal & Notary Services Co., Ltd. (DBD registration 0435567000061) issues full Thai tax invoices including 7% VAT, suitable for HR, immigration, finance and procurement reconciliation.
What identification do I need to bring to a notary appointment?
An original government-issued photo ID (passport for non-Thais; Thai national ID card for Thai citizens) plus the original document to be notarised. For corporate matters please also bring the certified company affidavit (หนังสือรับรองบริษัท) dated within the past 30 days.

Glossary of key terms
- Apostille
- A single-page certificate issued under the 1961 Hague Convention by a designated Competent Authority (in Thailand, the MFA Department of Consular Affairs) that authenticates the signature, seal, and capacity of the public official who signed the underlying public document. Eliminates the need for embassy legalisation in the 130 contracting parties.
- Notarial Services Attorney (NSA)
- A Thai lawyer who has completed the Lawyers Council of Thailand notarial training programme and is entered on the official notarial roster. Only NSAs may execute notarial acts in the Kingdom; foreign notaries public have no jurisdiction inside Thailand.
- MFA legalisation
- Authentication by the Ministry of Foreign Affairs Department of Consular Affairs, Chaeng Watthana, Bangkok. Required as the step between Thai notarisation and any foreign-embassy authentication, and as the source step for the Apostille.
- Embassy legalisation
- The final authentication step performed by the destination country's embassy or consulate in Bangkok. Required for documents destined for non-Hague members (China mainland, UAE, Saudi Arabia, Qatar, Kuwait, Vietnam for some document types).
- Kor Ror (คร.)
- The series of original Thai civil registry forms — kor ror 2 (marriage), kor ror 3 (marriage certificate), kor ror 22 (divorce), kor ror 6 (family book) — issued by the local amphur (district office). Only kor ror originals or amphur-certified copies are accepted for legalisation.
- DBD affidavit
- Corporate certificate issued by the Department of Business Development confirming a Thai juristic person's directors, registered capital, objectives and authorised signatories. Must be dated within 30 days of submission for notarial use.
- Certified translation
- A translation accompanied by a signed translator's affidavit listing the source/target language pair, translator credential number, and a dated statement of fidelity. In Thailand this is delivered on agency letterhead with the corporate seal.
- NAATI
- National Accreditation Authority for Translators and Interpreters (Australia). The mandatory translator credential for documents submitted to Australian Home Affairs, state births-deaths-marriages registries, AHPRA, and most Australian universities.
- Sworn translation
- A translation prepared by a court-sworn translator (notably required in Germany, France, Italy, Spain, Brazil). Thailand has no equivalent statutory framework; the closest is the MoJ-translator roster used for court proceedings.
- Police Clearance Certificate (PCC)
- Issued by the Royal Thai Police, Special Branch Bureau. Requires a ten-fingerprint card taken at a Royal Thai Police station; standard turnaround 14–21 business days.
- PDPA
- Thailand's Personal Data Protection Act, B.E. 2562 (2019). Every client file is held in a case-numbered audit trail with explicit consent, retention period, and right-of-erasure procedures.
- Express track
- Same-day or 24-hour processing tier available for MFA legalisation, Apostille, and selected embassy chains. Subject to MFA queue availability and a per-document surcharge.
Twelve most common rejection reasons & remedies
1. Document not in original form
Remedy: Re-issue the original from the issuing authority (amphur, DBD, university registrar, court clerk) before resubmission. Photocopies, scans, and digital prints are rejected by MFA.
2. Signature in red, gel, or stamp-pad ink
Remedy: Re-execute the document with black or blue ballpoint or fountain-pen ink. MFA OCR cannot reliably capture non-standard ink.
3. DBD affidavit older than 30 days
Remedy: Request a fresh DBD affidavit at any Department of Business Development counter (same-day issuance) and resubmit.
4. Translation lacks translator credential number
Remedy: Re-issue the translation with the translator's full name, certification body, credential number and dated affidavit on agency letterhead.
5. Multi-page document not page-numbered or unbound
Remedy: Number each page as n/total (e.g. 1/4, 2/4, 3/4, 4/4) and bind with a notarial ribbon or staple. MFA rejects loose pages.
6. Photograph older than six months
Remedy: Take a fresh 35×45 mm white-background photograph; visa-format photos are accepted by MFA and most embassies.
7. Police Clearance fingerprint card incomplete
Remedy: Return to a Royal Thai Police station for a clean ten-finger and palm-print card; partial prints invalidate the application.
8. Power of Attorney missing passport details
Remedy: Re-execute the POA listing both principal and attorney full passport number, nationality, date of birth and present address; both pages of the passport copy must be attached.
9. Apostille submitted before MFA legalisation
Remedy: Apostille is only available on documents that have first cleared MFA Consular Affairs. Submit the MFA legalisation step first, then the Apostille.
10. Embassy chain missing MFA cover sheet
Remedy: Most embassies require the green MFA cover sheet on top of the source document and translation. Re-attach in the correct order before resubmission.
11. Kor Ror submitted as plain photocopy
Remedy: Return to the issuing amphur for a certified copy bearing the amphur's seal and the registrar's wet signature; plain photocopies are not accepted.
12. Bilingual notarial certificate language mismatch
Remedy: Verify that the certificate is bilingual Thai/English (the embassy-friendly format) rather than Thai-only; re-issue if necessary.
