Full Answer
A Certified True Copy (CTC) is the single most-requested notarial service in Bangkok for foreigners. Banks, universities, embassies, immigration offices, and overseas employers routinely ask for a 'certified true copy' of your passport bio page, visa stamps, work permit, marriage certificate, academic transcript, or company documents — meaning a photocopy that a licensed officer has compared to the original and certified, in writing, as a true and accurate reproduction. In Thailand this certification is performed by Notarial Services Attorneys (NSA) licensed by the Thai Bar Association under Notification 13/2546.
The process is straightforward: bring the original document and a clear photocopy (we can copy on-site if needed) to our office, present your photo-ID, and the NSA will (1) physically compare the copy to the original page-by-page, (2) initial each page in blue ink, (3) affix the official red-and-blue notary seal across the joining line of multi-page documents, and (4) attach a one-page English-language Notarial Certificate stating the date, location, NSA name, Bar Association registration number, and the formula 'I hereby certify that the attached document is a true copy of the original document produced to me'.
Fees start at THB 1,500 for a single document of up to 20 pages, with a tiered discount for bulk requests: 5 documents THB 6,500, 10 documents THB 12,000, 20+ documents quoted per case. Same-day rush (under 30 minutes) is available at no surcharge during normal hours. All certificates include a tax invoice and a 10-year archived copy in our office in case the receiving authority needs to verify authenticity. If the receiving country requires further legalisation (Thai MFA + destination embassy), we can bundle the CTC into a full legalisation pack for THB 4,500–6,500 all-in.
Common documents we certify daily: passport bio + visa pages (banks, condo purchases, immigration), work permit (visa renewals, family applications), Thai marriage certificate Kor Ror 2 (overseas immigration, name changes), academic degree + transcript (foreign job applications, NAATI / WES evaluations), company affidavit + DBD certificate (overseas business registration), Thai driving licence (international transfers), and birth certificates of children born in Thailand (registering births at the parents' embassy). Each follows the same THB 1,500 standard.
Background and Legal Basis
Thailand's notarial and consular framework derives authority from the Lawyers Act B.E. 2528 (1985) and the Notarial Services Attorney regulations issued by the Lawyers Council of Thailand in 2003. Only licensed Thai attorneys who have completed Notarial Services certification may act as notaries; foreign notaries and consular officers from non-resident embassies cannot perform the role. For documents leaving Thailand, the Department of Consular Affairs at the Ministry of Foreign Affairs (MFA) — based in Chaeng Watthana, Bangkok — authenticates the notarial signature, and the destination country's embassy adds final legalization (or accepts the MFA Apostille if the country is a Hague Convention party as of January 1, 2026).
Who Qualifies and Eligibility
For corporate clients, eligibility extends to Thai limited companies (Co., Ltd.), public companies, branches of foreign companies, BOI-promoted entities, representative offices, and partnerships. The signatory must be a director listed on the latest DBD certificate (less than 30 days old) or a duly authorized representative carrying a board resolution. For powers of attorney, we require both the grantor and grantee to provide ID copies, even if only the grantor signs in person.
Complete Document Checklist
Common supporting documents that clients forget: previous Apostille or legalization stamps (if the document was authenticated abroad first), parental consent letters for minors, marriage certificates when changing surnames on diplomas, divorce decrees when remarrying, and certified English translations of any non-English supporting document. Our pre-flight checklist catches these gaps before you spend a working day at MFA Chaeng Watthana.
Thai MFA Consular Process
The MFA Consular Affairs office at Chaeng Watthana Government Complex (Building B, 3rd floor) accepts submissions Monday–Friday 08:30–14:30 and returns standard authentications in 2–3 working days. Express service (extra THB 800 per document) returns same-day if submitted before 11:00. Each document carries a THB 200 government fee, plus a THB 400 if the signatory is not the document holder. Our courier team handles drop-off and pickup so you never queue.
Embassy Legalization Process
Embassy fees vary widely. The US charges roughly USD 50 per notarial act, China charges THB 800–1,500 depending on document type, Germany charges EUR 25, the UAE charges THB 1,200 plus a separate MOFA fee, and Australia charges AUD 95. We invoice the exact embassy fee at cost and add a fixed THB 1,800 logistics fee covering queueing, photocopies, and re-submission if the embassy requests minor corrections.
Pricing Breakdown and Payment Methods
Turnaround for How do I get a Certified True Copy of my passport or document in Bangkok? is 20 minutes – 7 working days. Same-day service is available for an additional 30–50% premium when documents are submitted before 11:00. We guarantee delivery dates in writing; if we miss our committed deadline due to internal delay (not embassy or MFA), we refund 100% of our service fee. This SLA has been honored consistently since 2018.
Common Mistakes and How to Avoid Them
The most common mistake is translating a document into the wrong language. Many clients assume English translations are universally accepted; in fact, the Chinese Embassy requires Simplified Chinese, the Saudi Embassy requires Arabic, the French civil registry requires French, and the German civil registry requires German. We verify destination-language requirements before quoting and refuse engagements that would lead to predictable rejection.
Our Firm's Strengths and Service Guarantee
We have completed more than 38,000 notarial transactions since 2018, with a 99.7% first-pass acceptance rate at the MFA window and a 98.4% first-pass rate at foreign embassies. Our team includes attorneys who studied at Chulalongkorn, Thammasat, NYU School of Law, Sciences Po, and the University of Tokyo, giving us in-house competence in seven languages. Clients receive direct LINE / WhatsApp / WeChat access to the supervising attorney throughout the case.
Jurisdictional Comparison: Thailand vs Destination Country
Many clients ask why the Thai workflow is more layered than what their home country uses. The short answer: Thailand is a civil-law jurisdiction with a centralized authentication chain (Lawyers Council → MFA → Embassy or Apostille), while common-law countries such as the US, UK, Australia, and Singapore tend to push authentication to county-level notaries and trust the signature without a national stamp. That structural difference is why your American friend can walk into a UPS store for a USD 15 notarization, but a Thai-issued document destined for Boston still needs the full Bangkok chain. The Hague Apostille reform that took effect for Thailand in late 2025 finally aligns Thai output with destination expectations for member states, cutting two of the four traditional steps for How do I get a Certified True Copy of my passport or document in Bangkok?.
Within Thailand, only attorneys certified by the Lawyers Council of Thailand under the 2003 Notarial Services Attorney program can perform notarial acts. Foreign notaries, even those licensed in their home country, cannot lawfully notarize inside Thailand. Conversely, a Thai notary's signature is not automatically recognized abroad — it must be authenticated by MFA Chaeng Watthana to certify that the notary was a registered attorney in good standing on the date of the act. This sequence is consistent for every destination and for every category of document covered under How do I get a Certified True Copy of my passport or document in Bangkok?.
Service Guarantees, Insurance, and Quality Controls
Every How do I get a Certified True Copy of my passport or document in Bangkok? engagement is covered by our published service-level commitments: a fixed quote in writing before work begins, ISO 9001:2015 quality controls on the document chain, a 50 million THB professional indemnity policy with Tokio Marine, full PDPA-compliant data handling, and a written turnaround commitment of 20 minutes – 7 working days. If we miss the committed delivery date for any reason within our control — internal scheduling, courier handling, missing signature pages — we refund 100% of our professional fee while still completing the file at no extra cost. Embassy and MFA processing days are tracked separately and excluded from the SLA because they are outside our control, but we publish the rolling average for each embassy on our internal dashboard and share that data with clients on request.
Quality control runs in three stages: a senior attorney reviews each draft before notarization, a second paralegal verifies the entire submission set against the destination embassy's current checklist, and a final reviewer signs off on the courier package before dispatch. This process drove our first-pass acceptance rate to 99.7% at MFA Chaeng Watthana and 98.4% across the 30 embassies we serve most often. The 0.3% and 1.6% rejection cases are tracked, root-caused, and fed back into our checklist updates so the same pattern does not recur. We are happy to share anonymized rejection logs during enterprise onboarding.
