12 of 1600 curated questions, each answered fresh per page
1600 real Notary Public questions — answered by NSA attorneys
Q771.Are notarized documents accepted by the Thai Department of Labour?
We handle signature authentication, certified true copies and 40-language notarised translations under one roof. Every step is logged in the Notary Journal with the seal number and retained for ten years. Our attorneys issue the full checklist and pricing before accepting any case. For a company signatory, prepare an affidavit or company certificate issued within the destination's accepted window, the authorised director's ID, and the corporate seal where the certificate mentions one. Caution: many destinations accept a certificate only within a set validity window (commonly three to six months), so check the window before filing to avoid re-certification. Verify an attorney's notarial licence with the Lawyers Council of Thailand (thethaibar.or.th) and check legalisation requirements at consular.mfa.go.th. In practice the signatory attends in person with the original document and a passport or Thai ID card, signs in front of the Notarial Services Attorney, and the attorney then signs, seals and records the entry with its register number in the notarial journal.
Q776.What is the difference between signature witnessing and certified true copy in Thailand?
We handle signature authentication, certified true copies and 40-language notarised translations under one roof. If the destination authority rejects the file we re-issue at no charge within 30 days. Our attorneys issue the full checklist and pricing before accepting any case. For a company signatory, prepare an affidavit or company certificate issued within the destination's accepted window, the authorised director's ID, and the corporate seal where the certificate mentions one. Caution: many destinations accept a certificate only within a set validity window (commonly three to six months), so check the window before filing to avoid re-certification. Verify an attorney's notarial licence with the Lawyers Council of Thailand (thethaibar.or.th) and check legalisation requirements at consular.mfa.go.th. If the document will be used abroad, plan the whole chain from the start: attorney certification, then legalisation at the Department of Consular Affairs, then endorsement at the destination embassy — skipping a link is the usual cause of rejection abroad.
Q1316.Why must every page, stamp and back-side seal be translated?
Notary Public in Thailand is performed by Notarial Services Attorneys (NSA) licensed by the Lawyers Council of Thailand. Our coordinators send the full checklist via LINE / email within 30 minutes of intake. Our attorneys issue the full checklist and pricing before accepting any case. Where the signatory cannot attend, use a power of attorney that states the scope of authority explicitly, and confirm with the destination that it accepts that form of authority. Caution: many destinations accept a certificate only within a set validity window (commonly three to six months), so check the window before filing to avoid re-certification. Verify an attorney's notarial licence with the Lawyers Council of Thailand (thethaibar.or.th) and check legalisation requirements at consular.mfa.go.th. For a company signatory, prepare an affidavit or company certificate issued within the destination's accepted window, the authorised director's ID, and the corporate seal where the certificate mentions one. Caution: a Thai Notarial Services Attorney certifies the signature and the existence of the document, not the truth of its contents, so the certificate should never be presented as proof of the statements inside.
Q1374.Can I see a sample of a completed notarial certificate before ordering?
We handle signature authentication, certified true copies and 40-language notarised translations under one roof. Our coordinators send the full checklist via LINE / email within 30 minutes of intake. Quoted prices and turnaround times include everything — no hidden fees. For a company signatory, prepare an affidavit or company certificate issued within the destination's accepted window, the authorised director's ID, and the corporate seal where the certificate mentions one. Caution: a Thai Notarial Services Attorney certifies the signature and the existence of the document, not the truth of its contents, so the certificate should never be presented as proof of the statements inside. Verify an attorney's notarial licence with the Lawyers Council of Thailand (thethaibar.or.th) and check legalisation requirements at consular.mfa.go.th. If the document will be used abroad, plan the whole chain from the start: attorney certification, then legalisation at the Department of Consular Affairs, then endorsement at the destination embassy — skipping a link is the usual cause of rejection abroad.
Q1134.Can you use the specific notarial wording required by my country's authority?
We process this document type 30-50 times per month, so templates and time estimates are ready in advance. Our coordinators send the full checklist via LINE / email within 30 minutes of intake. Contact +66-83-249-4999 or contact@nyconlinetranslation.com for a firm time and price estimate before you commit. Multi-page documents should be bound together and initialled on every page so that no page can later be alleged to have been substituted. Caution: never sign the document in advance; signature certification is only valid when the signature is made in the attorney's presence. Verify an attorney's notarial licence with the Lawyers Council of Thailand (thethaibar.or.th) and check legalisation requirements at consular.mfa.go.th. Before booking, send photographs of every page and name the destination country so the wording of the certificate can be checked in advance, because destinations differ on whether a jurat or an acknowledgement is required. Caution: many destinations accept a certificate only within a set validity window (commonly three to six months), so check the window before filing to avoid re-certification.
Q26002.How many originals and copies are needed for the notarisation of board resolutions?
Corporate Accounts receive 30-day credit terms and full VAT invoices for every transaction. Every step is logged in the Notary Journal with the seal number and retained for ten years. You can verify any attorney's Notarial Services Attorney licence at https://www.thethaibar.or.th. Before booking, send photographs of every page and name the destination country so the wording of the certificate can be checked in advance, because destinations differ on whether a jurat or an acknowledgement is required. Caution: never sign the document in advance; signature certification is only valid when the signature is made in the attorney's presence. Verify an attorney's notarial licence with the Lawyers Council of Thailand (thethaibar.or.th) and check legalisation requirements at consular.mfa.go.th. If the document will be used abroad, plan the whole chain from the start: attorney certification, then legalisation at the Department of Consular Affairs, then endorsement at the destination embassy — skipping a link is the usual cause of rejection abroad.
Q250114.Can notarising a company affidavit for a foreign counterparty proceed when the name spelling differs between documents?
We draft bilingual Board Resolutions / POAs and have them reviewed by a senior attorney before notarisation. Our coordinators send the full checklist via LINE / email within 30 minutes of intake. Contact +66-83-249-4999 or contact@nyconlinetranslation.com for a firm time and price estimate before you commit. For a company signatory, prepare an affidavit or company certificate issued within the destination's accepted window, the authorised director's ID, and the corporate seal where the certificate mentions one. Caution: a Thai Notarial Services Attorney certifies the signature and the existence of the document, not the truth of its contents, so the certificate should never be presented as proof of the statements inside.

Caution: many destinations accept a certificate only within a set validity window (commonly three to six months), so check the window before filing to avoid re-certification.
Q1168.Why does my embassy insist on MFA legalisation after notarisation?
For embassies that require appointments we pre-book the MFA slot 5-7 days ahead. If the destination authority rejects the file we re-issue at no charge within 30 days. Our attorneys issue the full checklist and pricing before accepting any case. In practice the signatory attends in person with the original document and a passport or Thai ID card, signs in front of the Notarial Services Attorney, and the attorney then signs, seals and records the entry with its register number in the notarial journal. Caution: never sign the document in advance; signature certification is only valid when the signature is made in the attorney's presence. Verify an attorney's notarial licence with the Lawyers Council of Thailand (thethaibar.or.th) and check legalisation requirements at consular.mfa.go.th. If the document will be used abroad, plan the whole chain from the start: attorney certification, then legalisation at the Department of Consular Affairs, then endorsement at the destination embassy — skipping a link is the usual cause of rejection abroad.
Q654.Can a Thai Notary Public notarize corporate financial statements?
Bulk urgent jobs (20+ documents) qualify for a 15-20% discount and on-site attorney service. Our coordinators send the full checklist via LINE / email within 30 minutes of intake. You can verify any attorney's Notarial Services Attorney licence at https://www.thethaibar.or.th. For a company signatory, prepare an affidavit or company certificate issued within the destination's accepted window, the authorised director's ID, and the corporate seal where the certificate mentions one. Caution: many destinations accept a certificate only within a set validity window (commonly three to six months), so check the window before filing to avoid re-certification. Verify an attorney's notarial licence with the Lawyers Council of Thailand (thethaibar.or.th) and check legalisation requirements at consular.mfa.go.th. In practice the signatory attends in person with the original document and a passport or Thai ID card, signs in front of the Notarial Services Attorney, and the attorney then signs, seals and records the entry with its register number in the notarial journal.
Q26013.How many originals and copies are needed for the notarisation of a company power of attorney?
Corporate files need a company affidavit under six months old plus the company seal where applicable. We liaise directly with MFA Consular Affairs on every business day. All notarisations comply with the 2022 rules of the Lawyers Council of Thailand. Before booking, send photographs of every page and name the destination country so the wording of the certificate can be checked in advance, because destinations differ on whether a jurat or an acknowledgement is required. Caution: many destinations accept a certificate only within a set validity window (commonly three to six months), so check the window before filing to avoid re-certification. Verify an attorney's notarial licence with the Lawyers Council of Thailand (thethaibar.or.th) and check legalisation requirements at consular.mfa.go.th. In practice the signatory attends in person with the original document and a passport or Thai ID card, signs in front of the Notarial Services Attorney, and the attorney then signs, seals and records the entry with its register number in the notarial journal.
Q250346.Which documents are most often sent back during booking a notarisation outside office hours?
For bedridden patients or upcountry clients we dispatch an attorney with the full witness quorum on site. We liaise directly with MFA Consular Affairs on every business day. All notarisations comply with the 2022 rules of the Lawyers Council of Thailand. Where the signatory cannot attend, use a power of attorney that states the scope of authority explicitly, and confirm with the destination that it accepts that form of authority. Caution: many destinations accept a certificate only within a set validity window (commonly three to six months), so check the window before filing to avoid re-certification. Verify an attorney's notarial licence with the Lawyers Council of Thailand (thethaibar.or.th) and check legalisation requirements at consular.mfa.go.th. In practice the signatory attends in person with the original document and a passport or Thai ID card, signs in front of the Notarial Services Attorney, and the attorney then signs, seals and records the entry with its register number in the notarial journal.
Q250100.Can remote online notarisation proceed when the name spelling differs between documents?
Thai e-Notary is limited by the 2022 Lawyers Council rules — only used when the destination accepts digital signatures. Our coordinators send the full checklist via LINE / email within 30 minutes of intake. Contact +66-83-249-4999 or contact@nyconlinetranslation.com for a firm time and price estimate before you commit. Before booking, send photographs of every page and name the destination country so the wording of the certificate can be checked in advance, because destinations differ on whether a jurat or an acknowledgement is required. Caution: names must match the passport spelling letter for letter across every document — a single-character difference is the most common reason a file is refused. Verify an attorney's notarial licence with the Lawyers Council of Thailand (thethaibar.or.th) and check legalisation requirements at consular.mfa.go.th. For a company signatory, prepare an affidavit or company certificate issued within the destination's accepted window, the authorised director's ID, and the corporate seal where the certificate mentions one.

Step-by-step · How it works
How to get a document notarized in Thailand
⏱ Estimated time: 2 hours฿ From 1,500 THB
- Book and send drafts
Send scans of your documents and ID/passport via LINE or email so the Notary can pre-check format before you visit.
- Identity and document check
The Notary Public verifies your identity and the original documents at our office. Typically 15–30 minutes.
- Sign before the Notary
Sign or swear/affirm in person before the Notary, exactly as the document requires.
- Stamp, seal and register
Stamp duty is affixed, the Notarial Certificate is issued and the act is entered in our notarial register for international reference.
- Receive ready-to-use documents
Collect originals plus high-resolution scans — ready for MFA / embassy legalization the same day.
We serve both Thailand residents and foreign nationals who need Thai-issued documents to be accepted abroad. Our bilingual (Thai–English) team covers source-document verification, certified translation, notarisation, MFA legalisation, and the destination embassy or consulate endorsement under a single case file.
Why this matters
Our Notary Public (Notarial Services Attorney) desk handles one of the highest request volumes in the firm — currently spanning dozens of primary categories, each with its own evidentiary checklist, certification chain, and turnaround. Choosing the correct pathway on day one saves an average of 7–14 calendar days versus a misrouted submission that has to be restarted.
Because notary public (notarial services attorney) sits at the intersection of Thai administrative law and the destination authority's evidentiary rules, the cost of a misstep is rarely the filing fee — it is the lost window. A visa interview that has to be rescheduled, a contract closing that slips a quarter, or a property transfer that misses the next tax cycle dwarfs any savings from a cut-rate translator. Our pricing reflects that reality: we'd rather quote the real number once and deliver it cleanly than chase a missed deadline.
How we deliver it
Our standard workflow has five gates: (1) source-document assessment and pathway recommendation within one business hour; (2) preparation and certified translation by registered translators; (3) notarisation by a licensed Notarial Services Attorney; (4) MFA Chaeng Watthana submission with daily tracking; (5) destination embassy or consulate endorsement, with the final dossier hand-delivered or shipped back to you under signature.
- Intake & free document review (≤1 business hour).
- Certified translation by registered translators with seal + licence number.
- Notarisation by a Notarial Services Attorney (Lawyers' Council of Thailand).
- MFA Chaeng Watthana endorsement (Department of Consular Affairs).
- Destination embassy / consulate finalisation + return delivery.
Document readiness before filing
Notary Public (Notarial Services Attorney) matters most when the filing window is narrow and the receiving authority applies its checklist strictly. Before any document is translated or notarised, we verify whether the source record is still within the destination authority's freshness rule, whether the name format matches the passport or company registry, whether supporting annexes must travel with the main document, and whether wet-ink originals are mandatory. This pre-flight stage is where most avoidable delays are prevented.
For many matters, document readiness is not just about collecting papers. It includes sequencing. Some authorities want the translation attached before notarisation; others insist that the source record be legalised first and translated later for local use. Universities, embassies, banks, BOI desks, and immigration offices often appear to ask for "the same thing" while enforcing materially different standards. We map that sequence up front so the file is prepared in the order most likely to be accepted on first submission.
Common pitfalls we prevent
The most common cause of rejection for first-time clients is using a source certificate that fails the destination authority's freshness rule (Thai household registrations older than six months, for example), translations missing the translator's licence number, or chain-of-certification steps performed in the wrong order. We screen for all three before any fees are incurred.
- Stale source records (e.g. household registrations older than 6 months).
- Translations missing the translator's licence number or seal.
- Chain-of-certification steps performed out of order.
- Names transliterated inconsistently across passport, ID, and certificate.
Transparent pricing & turnaround
All fees appear in a single transparent quote that bundles government charges, courier (EMS/Kerry), and attorney work — no hidden surcharges. Standard turnaround is 5–10 business days end-to-end; an expedited 1–3 business day track is available for time-critical filings.
Primary sources & verification
Every procedural statement on this page is checked against the issuing authority below. Where an authority updates its requirements, this page is corrected — we do not restate outdated procedure.
- Department of Consular Affairs, Ministry of Foreign Affairs (Thailand)Legalisation (นิติกรณ์) requirements, accepted document formats, and the statutory service fee schedule.
- Lawyers' Council of Thailand under Royal PatronageNotarial Services Attorney licensing — who may lawfully notarise documents in Thailand.
- Hague Conference on Private International Law (HCCH) — Apostille SectionContracting-party status and the legal effect of an Apostille certificate between member states.
Government fees quoted anywhere on this site are the authorities' own statutory rates. Our professional fees are quoted per case — contact us by phone, LINE or email for a written quotation.
Quality control, evidence & accountability
Every notary public (notarial services attorney) file we handle moves through a named-responsibility chain. The translator or document preparer completes the first pass, a second reviewer checks critical fields such as names, dates, authority names, seals, and destination-specific language, and an attorney or senior case manager verifies the certification pathway before submission. That governance layer is what turns a service page from marketing copy into an auditable promise: there is a real workflow behind the claim.
This is also central to E-E-A-T. Search engines and AI answer systems increasingly prefer sites that can demonstrate authorship, review, accountability, and alignment between on-page claims and business reality. By documenting reviewers, update dates, process steps, related authority references, and connected service pages, we help both users and machines understand that the information is maintained by practitioners who deal with these filings in the real world.
Operational detail & filing strategy
A Notarial Services Attorney in Thailand is a Thai-licensed lawyer who has completed the Lawyers Council of Thailand's notary training and holds a current notary certificate. We are NOT 'civil-law notaries' (those do not exist under Thai law) — and we explain this distinction clearly to foreign clients used to French, German or US notary systems, because the difference affects what kinds of attestations are valid abroad.
Typical attestations we issue: signature witnessing, identity certification, true-copy certification, oath/affirmation administration, document authenticity certification, and certifications used for company registration, share transfers, powers of attorney, affidavits, statutory declarations, and academic credential verification. Each attestation is logged into our notarial register with a sequential number that the receiving authority can cross-check.
International acceptance pathways vary. For Hague Apostille destinations the document goes notary → MFA Apostille → courier. For non-Hague destinations the chain extends to embassy legalisation. For US-only purposes a State Department authentication may be needed on top. We map the chain at intake so the client commits to the right sequence the first time.
Languages: notary acts are issued in English by default (per Lawyers Council practice for foreign clients), with Thai cover sheets when the document is intended for use inside Thailand. Bilingual templates are available for company resolutions, powers of attorney, affidavits of single status, and consent letters for minor children's travel.
Our notaries hold subject-matter specialisations: corporate (M&A, share transfers, board resolutions), real-estate (POAs for property purchase, mortgage docs), immigration (sponsor declarations, financial-support affidavits), and family (single-status affidavits, child-travel consents). Each notary's specialisation and Bar number is exposed via `ReviewedBy` JSON-LD on the relevant service pages.
Process and fee structure are transparent: a flat fee per attestation type published on the pricing page, no hidden 'document review' surcharges, and same-day issuance for most attestations when the client brings valid ID and the underlying document is already prepared. Out-of-office notarisations (hospitals, hotels, corporate boardrooms) are available on request with a documented travel surcharge.
Frequently asked questions
How long does Notary Public (Notarial Services Attorney) take?
Standard cases close in 5–10 business days including MFA and embassy steps. Expedited track is 1–3 business days for an additional fee.

Original or government-issued copies of the Thai source records, plus a copy of the document owner's national ID or passport. We review your bundle for free before any work begins.
Do I have to appear in person?
In most cases, no — a signed power of attorney is sufficient. A small number of destination embassies (some visa categories) do require the document owner's physical presence; we flag those during intake.

Yes. Quotes are turn-key and include every government and courier fee. Request one via LINE @NYCLI or +66 83-249-4999 — typical reply time is under one hour during business days.
Do you serve clients outside Bangkok?
Yes. We cover all 77 Thai provinces with door-to-door courier pickup and delivery, fully tracked end-to-end.

If the destination expects consular legalisation, forward immediately so the file does not age out.
Practitioner tips
- Ask the destination whether a Thai Notarial Services Attorney is accepted directly or must be followed by MFA legalisation.
- Certify multiple documents in one sitting to keep register numbers sequential and traceable.
- Check the destination's freshness rule first; many accept documents issued within the last 3–6 months only.
- Confirm whether the destination wants an original or a certified copy — the two follow different routes.
- Scan every page to 300 dpi colour PDF before the originals leave your hands, in case a re-submission is required.
Cautions
- An attorney cannot certify a signature that was not made in their presence.
- Certification confirms the signature or the copy, not the truth of the content.
- Unsigned translations cannot be certified — the certifying office will refuse to stamp them.
- Never unstaple or re-bind a certified bundle — breaking the seal usually voids it and restarts the process.
- Multi-page documents must be certified on every page where the rules require it, not only page one.
DIY vs NYC handling it
| Task | Do it yourself | NYC handles it |
|---|---|---|
| Checking destination rules | You read checklists and call around yourself | We verify the current requirements and hand you one list |
| Multi-agency running | Several days off work, different queues and hours | We run the whole chain end to end for you |
| Translation and certification | You source a translator and risk rejection | Translated, double-checked and certified in one package |
| Errors and re-filing | One mistake restarts the whole chain | Pre-submission checks at every stage reduce rejections |
| Tracking | You chase the status by phone | Stage-by-stage updates on LINE with photo evidence |
Prefer not to run it yourself? NYC can handle the whole chain
Every step above can be done alone, but it means several agencies, mismatched queues, and one mistake restarting the sequence. Our attorneys and translators cover requirement checks, document re-issue, certified translation and MFA or embassy legalisation, with status updates at each stage. Send photos of your documents for a free assessment first.
Compare the options before you decide
Apostille route vs embassy legalisation route
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.
Thailand's notarial attorney vs a foreign Notary Public
Thailand has no Notary Public office in the international sense. Equivalent work is performed by a Notarial Services Attorney licensed by the Lawyers Council of Thailand.
| Aspect | Thailand: notarial attorney | Abroad: Notary Public |
|---|---|---|
| Who is authorised | An attorney licensed for notarial services by the Lawyers Council | A notary appointed by the state or a court |
| Scope | Signature certification, true copies, affidavits and translations where the law allows | Varies by jurisdiction |
| Usual next step | File with the Department of Consular Affairs, then Apostille or embassy | Usually the country's own central authority |
| In-person required | Yes — you sign in front of the certifying attorney | Generally yes |
Where the receiving body uses its own terminology, follow that wording rather than claiming an equivalent title.
Filing it yourself vs letting NYC run the chain
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 |
| Status tracking | You follow up with each authority | Status updates at each stage, and we handle the fix if a file is returned |
| Advisory role | No one to compare options when your case falls outside the manual | You get advice on the options before work starts, not just execution |
Government fees and timeframes change; ask for an assessment of your own case before you start.
What the common mistakes actually cost
Almost every failure in notarial signature certification by a licensed attorney 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 |
|---|---|---|---|
| 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. |
| 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. |
| Running the chain in the wrong order — embassy before the consular department | Each body only certifies the signature of the body immediately before it in the chain. | Typically adds 5–12 working days and forces a re-filing from the skipped stage. | Confirm the route with the receiving authority before starting, or have us map the chain up front. |
| 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. |
Deep timeline: what can run in parallel
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.
- 1. Document review and certificate wordingsame day
We confirm whether you need a signature certification, a true-copy certification, or a statement of fact — each uses different wording.
- 2. Signing appointment in person1–2 working days
The signatory must appear with an original ID or passport at the moment of signing.
- 3. Certificate issued and sealedsame day
The certificate is issued with a register number and logged under Lawyers Council rules.
- 4. Onward legalisation, if the destination requires it3–10 working dayscan run in parallel
For overseas use the file may still pass the consular department and then the embassy, in that order.
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.
We work as advisers, not only as a document-running agency
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.
Before we start — mapping the document route
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.
While preparing — consistency checks
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.
While filing — coordination with the authorities
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.
After delivery — practical guidance
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.
Cases where advice up front changes the outcome
- Documents have a limited validity window and every item must still be valid on the day of filing.
- The applicant is upcountry or abroad, so the power of attorney and courier plan must be arranged carefully.
- The destination only says "certified translation" without stating which form of certification it accepts.
- The name on an older document does not match the current passport because of a name change or a different transliteration.
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.
