Jurisdictions (12)

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 End-to-End FDI — BOI · EEC · Amity · LTR · IBC · ICSID 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 end-to-end fdi — boi · eec · amity · ltr · ibc · icsid 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.

  1. Intake & free document review (≤1 business hour).
  2. Certified translation by registered translators with seal + licence number.
  3. Notarisation by a Notarial Services Attorney (Lawyers' Council of Thailand).
  4. MFA Chaeng Watthana endorsement (Department of Consular Affairs).
  5. Destination embassy / consulate finalisation + return delivery.

Document readiness before filing

End-to-End FDI — BOI · EEC · Amity · LTR · IBC · ICSID 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.

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 end-to-end fdi — boi · eec · amity · ltr · ibc · icsid 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.

Frequently asked questions

How long does End-to-End FDI — BOI · EEC · Amity · LTR · IBC · ICSID 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.

What documents do I need to prepare?

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.

Is the quote final?

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.

Which destination countries are supported?

168 destinations including the 125 Hague Apostille jurisdictions and Non-Hague destinations that require in-Thailand embassy endorsement. See the Legalization hub for the full directory.

Cross-service questions, answered by the NYC Legal team

299. Does the Italian Embassy accept translations done by standard translators, or is a sworn translator mandatory?

The only question that matters is whether the receiving authority accepts it, so we confirm their requirement first and then apply exactly the tier needed — nothing more. One coordinator owns the matter end to end and reports progress by LINE or email at the intervals you set. Send your documents for a free assessment at +66-83-249-4999 or contact@nyconlinetranslation.com. 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. Caution: processing time depends on each authority's queue, so allow buffer before the date the document is actually needed. Private documents such as powers of attorney or contracts must first pass a notarial services attorney before they can enter the legalisation stage. Caution: never unbind, trim or separate pages after an authority has sealed the set — doing so voids the certification. 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. Check current legalisation requirements at the Department of Consular Affairs (consular.mfa.go.th) and Apostille membership at hcch.net.

423. In cross-border litigation, can your lawyers certify translated court judgments for execution in foreign jurisdictions?

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. Government fees follow each authority's published rate, while professional fees are quoted per case by document count and destination, in full before work starts. Send your documents for a free assessment at +66-83-249-4999 or contact@nyconlinetranslation.com. Private documents such as powers of attorney or contracts must first pass a notarial services attorney before they can enter the legalisation stage. Caution: processing time depends on each authority's queue, so allow buffer before the date the document is actually needed. 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: 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. Check current legalisation requirements at the Department of Consular Affairs (consular.mfa.go.th) and Apostille membership at hcch.net.

305. What should I prepare when hiring a district office interpreter for a cross-cultural marriage registration?

Interpreters are matched to the setting: court and police station, government and embassy, medical, simultaneous booth work, and remote VRI/OPI. Quotations separate government fees from professional fees line by line, so nothing appears on the invoice that was not in the quote. 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: 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. Request more than one certified set when several authorities are involved, because most receiving offices keep the certified copy and do not return it. Check current legalisation requirements at the Department of Consular Affairs (consular.mfa.go.th) and Apostille membership at hcch.net.

Which documents must be prepared for a re-entry document set for a returning expatriate?

Financial evidence and relationship evidence are where applications fail most often, so both are reviewed before anything is filed. If the receiving authority rejects a file for a reason attributable to our work, we correct and re-file it at no additional professional fee. Talk to the NYC Legal team on any business day — you get a working plan, not a generic price list.

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: government fees follow the authority's published rate and are separate from professional fees; check the current rate on the official website first. Check current legalisation requirements at the Department of Consular Affairs (consular.mfa.go.th) and Apostille membership at hcch.net.

362. Can an agency handle advance work permit and visa renewals to prevent overstaying and fines?

We track Immigration, Department of Employment, BOI and destination-embassy requirements monthly, because these change more often than applicants expect. If the receiving authority rejects a file for a reason attributable to our work, we correct and re-file it at no additional professional fee. Send your documents for a free assessment at +66-83-249-4999 or contact@nyconlinetranslation.com.

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. Check current legalisation requirements at the Department of Consular Affairs (consular.mfa.go.th) and Apostille membership at hcch.net.

473. Do you provide financial background checks on expats to give luxury property landlords peace of mind?

Tax and land-registry documents carry terminology that cannot be paraphrased, so we work from Revenue Department and Land Department glossaries. Government fees follow each authority's published rate, while professional fees are quoted per case by document count and destination, in full before work starts. Send your documents for a free assessment at +66-83-249-4999 or contact@nyconlinetranslation.com.

Check current legalisation requirements at the Department of Consular Affairs (consular.mfa.go.th) and Apostille membership at hcch.net.

Which documents must be prepared for certified documents for an infrastructure tender bid?

Tender and construction contracts have hard deadlines, so team capacity is locked and interim delivery checkpoints are set before the closing date. Quotations separate government fees from professional fees line by line, so nothing appears on the invoice that was not in the quote. Tell us where the document will be used and you will get a plan and a price the same business day. 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. 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.

539. What type of business license is required before applying for broadcasting frequency allocation and licensing support?

Company name, director names and registered address are cross-checked across every document, because a single spelling mismatch triggers a rejection. 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. Request more than one certified set when several authorities are involved, because most receiving offices keep the certified copy and do not return it.

330. Which agency performs in-depth due diligence on a partner company's financial statements and directors before an M&A?

M&A and fundraising work demands speed and confidentiality, so we sign the NDA before intake and ring-fence a closed team for the matter. Quotations separate government fees from professional fees line by line, so nothing appears on the invoice that was not in the quote. Talk to the NYC Legal team on any business day — you get a working plan, not a generic price list.

Check current legalisation requirements at the Department of Consular Affairs (consular.mfa.go.th) and Apostille membership at hcch.net.

343. Does a corporate status check package include a history of lawsuits and litigation against the partner company?

Tax and land-registry documents carry terminology that cannot be paraphrased, so we work from Revenue Department and Land Department glossaries. 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. Private documents such as powers of attorney or contracts must first pass a notarial services attorney before they can enter the legalisation stage. Caution: government fees follow the authority's published rate and are separate from professional fees; check the current rate on the official website first.

Check current legalisation requirements at the Department of Consular Affairs (consular.mfa.go.th) and Apostille membership at hcch.net.

559. Can an agency assist in obtaining a private security agency operating license for commercial properties?

Electronic documents must be traceable to their source, so deliverables ship with an audit trail whenever the receiving party asks for one. Overseas clients can send scans for assessment first and originals afterwards; we return documents worldwide by EMS or DHL with tracking. Tell us where the document will be used and you will get a plan and a price the same business day. Request more than one certified set when several authorities are involved, because most receiving offices keep the certified copy and do not return it. Caution: government fees follow the authority's published rate and are separate from professional fees; check the current rate on the official website first.

382. Do you offer copyright and software patent registration to protect the intellectual property of tech startups?

Cross-border wills and estates must be read against the destination jurisdiction, and we coordinate local counsel where that is required. Government fees follow each authority's published rate, while professional fees are quoted per case by document count and destination, in full before work starts. Send your documents for a free assessment at +66-83-249-4999 or contact@nyconlinetranslation.com.

Step-by-step · How it works

How to obtain BOI promotion for foreign-invested business in Thailand

⏱ Estimated time: 90 days฿ From 80,000 THB
  1. Select a BOI-promoted activity

    Review the BOI Activity List across 8 categories (Agriculture, Manufacturing, Service, Digital, etc.) — confirm tax incentive band A1–B2.

  2. Prepare Feasibility Study and Business Plan

    Project description, market analysis, 5-year financial projection, technology transfer plan — the core documents BOI reviews.

  3. Submit BOI online application

    File via e-Investment Promotion portal with corporate documents, shareholder structure, and capital plan. BOI invites you to an oral hearing within 30 days.

  4. Receive BOI Promotion Certificate

    On approval, BOI issues the promotion certificate (~30 days). Use it to register the BOI company, apply for work permits, and unlock land-ownership rights.

  5. Post-promotion compliance

    File annual reports, comply with conditions (employment ratio, technology transfer); maintain the audit trail for the BOI inspection cycle.

Full service playbook — Legal drafting & document review

Drafting and review start from the facts and the parties' objectives, then select the document structure, language and enforcement route that suit the destination.

Responsible authority: The responsible attorney and the authority relevant to the matter

Documents to prepare

  • Identity documents for every party, plus company affidavits for corporates
  • Underlying paperwork such as prior contracts, invoices or payment evidence
  • The commercial terms wanted — scope, term and termination conditions
  • Related title or registration documents where applicable
  • Requirements of the authority or country where the document will be used

Step-by-step process

  1. 1. Fact interview and objective setting1–2 business days

    Capture what each party needs and the risk each can accept before choosing the instrument.

  2. 2. First draft2–5 business days

    Draft parties, scope, consideration, term, termination and governing law.

  3. 3. Client review round1–3 business days

    Refine wording and reconcile defined terms across the whole document.

  4. 4. Bilingual version for overseas use1–3 business days

    Produce a Thai–English version stating which language prevails.

  5. 5. Execution and certification3–10 business days

    Sign before a notarial services attorney, then add an Apostille or legalisation if used abroad.

Practitioner tips

  • State the prevailing language explicitly to avoid interpretation disputes.
  • Keep negotiation records and emails as evidence of the parties' intent.
  • Match the Latin spelling of your name to your passport exactly — receiving authorities compare character by character.
  • Scan every page to 300 dpi colour PDF before the originals leave your hands, in case a re-submission is required.
  • Photograph each seal or stamp after every stage so you can trace the file if follow-up is needed.

Cautions

  • Website content is general information, not advice on your specific matter.
  • Copying a template without adapting the facts often leaves clauses unenforceable.
  • 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.
  • Do not write on, amend, or correction-fluid an official document; request a fresh copy from the issuing office instead.

DIY vs NYC handling it

TaskDo it yourselfNYC handles it
Checking destination rulesYou read checklists and call around yourselfWe verify the current requirements and hand you one list
Multi-agency runningSeveral days off work, different queues and hoursWe run the whole chain end to end for you
Translation and certificationYou source a translator and risk rejectionTranslated, double-checked and certified in one package
Errors and re-filingOne mistake restarts the whole chainPre-submission checks at every stage reduce rejections
TrackingYou chase the status by phoneStage-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.

AspectApostille routeEmbassy legalisation route
When it appliesDestination is a party to the Apostille ConventionDestination does not accept an Apostille
Final authorityDepartment of Consular Affairs, Ministry of Foreign AffairsThe destination country's embassy or consulate in Thailand
Typical number of stepsFewer — the chain ends at the central authorityMore — central authority first, then the embassy
Approximate timeframeShorter, still subject to the authority's queueLonger, because the embassy appointment queue is added
Common rejection causeTranslation does not match the original, or the copy was not issued by the authorityThe 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.

AspectThailand: notarial attorneyAbroad: Notary Public
Who is authorisedAn attorney licensed for notarial services by the Lawyers CouncilA notary appointed by the state or a court
ScopeSignature certification, true copies, affidavits and translations where the law allowsVaries by jurisdiction
Usual next stepFile with the Department of Consular Affairs, then Apostille or embassyUsually the country's own central authority
In-person requiredYes — you sign in front of the certifying attorneyGenerally 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.

AspectDo it yourselfNYC handles it
Checking destination rulesRead each authority's notice yourself and confirm by phoneChecked before you start, with the order the receiving authority accepts
TravelSeveral agencies with queues that rarely line up in one dayDocuments move by courier or online except where the law requires you in person
Rejection riskOne mismatch — a name spelled differently from the passport — restarts the chainNames, dates and stamps are cross-checked before every filing
Status trackingYou follow up with each authorityStatus updates at each stage, and we handle the fix if a file is returned
Advisory roleNo one to compare options when your case falls outside the manualYou 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 legal instruments and drafting 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.

MistakeWhy it happensTime costHow to prevent it
Booking the wrong service channel or appointment typeEach 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.
Filing an incomplete set — missing an ID copy or a power of attorneyCompleteness is checked at the counter; an incomplete file is not accepted at all.Typically adds 1–5 working days per return trip.Work from a written checklist and re-check it before leaving, including every copy that needs a signature.
Self-translating, or using a translator the destination does not recogniseSome countries accept only registered translators, others only translations certified by a Thai government body.Typically adds 4–10 working days for a fresh translation and a restarted chain.Ask the destination exactly which form of translation it accepts, then match the translator to that form from the start.
Planning without allowing for public and embassy holidaysEmbassies 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.
Running the chain in the wrong order — embassy before the consular departmentEach 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.

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. 1. Advisory call to fix scope and form1–2 working days

    Parties, delegated powers, and the intended effect are settled before drafting to avoid later rewrites.

  2. 2. Drafting and professional review2–5 working days

    Wording, signing authority, and annexes are checked against what the destination requires.

  3. 3. Execution and certification1–3 working days

    Signatories appear with original identity documents and the instrument is certified in the required form.

  4. 4. Translation and legalisation for overseas use3–15 working dayscan run in parallel

    Possible once the original is fully executed; timing depends on destination and queues.

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

  • A file was already returned once and the real cause has to be identified before refiling.
  • The destination only says "certified translation" without stating which form of certification it accepts.
  • Documents have a limited validity window and every item must still be valid on the day of filing.
  • 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.

ประเด็นสำคัญที่ต้องรู้

คำถามที่พบบ่อย

What does the Corporate fee include?
Professional service fee, government fees at official rates, domestic EMS, and international courier where applicable — each listed separately in the quote.
Do I have to visit the office?
No. Send originals by EMS or book a Bangkok pickup; completed documents are returned by domestic post or international courier.
Will the Corporate result be accepted abroad?
It depends on the destination. Hague Convention member states accept an apostille directly; non-member states need an additional embassy legalization step.
What do you need to start Corporate?
A photo or scan of the original plus the destination country and receiving authority. We review it free of charge and reply with the shortest valid routing.

Corporate

With "Corporate", the outcome is decided by certification order rather than translation alone. We map the full International Document Services routing before anything is filed, so the chain holds at the destination office. We handle files from Bangkok, upcountry, and overseas clients working through a power of attorney. Files are signed off by an attorney registered as a Notarial Services Attorney with the Lawyers Council of Thailand, working alongside Ministry of Justice-recognized translators and our consular liaison desk. Fees are itemized before work begins: professional service fee, government fees, domestic EMS, and international courier (DHL/FedEx). Choose standard turnaround of 5-7 business days or rush turnaround of 1-3 business days.

What to prepare before filing Corporate

  • Original document required for Corporate (or a freshly issued certified copy within its validity window)
  • Copy of national ID or passport, signed and dated as a true copy
  • Power of attorney (if a representative will handle it) with a 30 THB revenue stamp
  • Destination details: country, receiving authority, purpose, and required deadline

Corporate: the working sequence

  • 1. Send scanned copies of the Corporate source documents via LINE/email for a free initial review.
  • 2. We confirm eligibility and issue a written quote with a committed turnaround.
  • 3. You deliver originals to our office (or book a Bangkok pickup) and pay a 50% deposit.
  • 4. We translate, certify, and submit to each Thai authority in the order the destination accepts.
  • 5. Final documents are scanned and emailed for your review before physical dispatch.
  • 6. We ship by EMS domestically and DHL/FedEx internationally, with tracking numbers.

Timeline and fees for Corporate

  • Standard turnaround for Corporate: 5-7 business days from receipt of complete originals.
  • Rush turnaround: 1-3 business days (rush surcharge applies).
  • Government fees are charged at official rates with no markup.
  • Domestic EMS at Thailand Post rates; international DHL/FedEx at actual weight-based rates.

Re-filing triggers in Corporate matters

  • Submitting an uncertified photocopy instead of the original — the receiving office will not review it and you rejoin the queue.
  • Originals outside the validity window — many destinations require documents issued within 3-6 months. Confirm with the receiving authority first.
  • Dates that disagree across documents — this must be fixed at the issuing agency; it cannot be corrected at the translation stage.
  • Name mismatch between the document and the passport — embassies reject these. Correct it at the district office before translating.

Step-by-step process

  1. 1Obtain fresh DBD recordsCompany affidavit, shareholder list, MOA and financials as the destination requires.
  2. 2Verify signing authorityWe confirm the signatory is authorised in the affidavit and add a power of attorney when delegated.
  3. 3Certified legal/business translationEntity terms, director names and capital figures are kept exact.
  4. 4Certify for overseas useNotary + consular department + embassy, or an apostille set depending on destination.

Documents you need to prepare

Compare the options before you decide

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.

AspectThailand: notarial attorneyAbroad: Notary Public
Who is authorisedAn attorney licensed for notarial services by the Lawyers CouncilA notary appointed by the state or a court
ScopeSignature certification, true copies, affidavits and translations where the law allowsVaries by jurisdiction
Usual next stepFile with the Department of Consular Affairs, then Apostille or embassyUsually the country's own central authority
In-person requiredYes — you sign in front of the certifying attorneyGenerally yes

Where the receiving body uses its own terminology, follow that wording rather than claiming an equivalent title.

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.

AspectApostille routeEmbassy legalisation route
When it appliesDestination is a party to the Apostille ConventionDestination does not accept an Apostille
Final authorityDepartment of Consular Affairs, Ministry of Foreign AffairsThe destination country's embassy or consulate in Thailand
Typical number of stepsFewer — the chain ends at the central authorityMore — central authority first, then the embassy
Approximate timeframeShorter, still subject to the authority's queueLonger, because the embassy appointment queue is added
Common rejection causeTranslation does not match the original, or the copy was not issued by the authorityThe embassy's own form or language requirement was not followed

Verify the current convention status and embassy conditions before filing.

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.

AspectDo it yourselfNYC handles it
Checking destination rulesRead each authority's notice yourself and confirm by phoneChecked before you start, with the order the receiving authority accepts
TravelSeveral agencies with queues that rarely line up in one dayDocuments move by courier or online except where the law requires you in person
Rejection riskOne mismatch — a name spelled differently from the passport — restarts the chainNames, dates and stamps are cross-checked before every filing
Status trackingYou follow up with each authorityStatus updates at each stage, and we handle the fix if a file is returned
Advisory roleNo one to compare options when your case falls outside the manualYou 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.

5 company registration and corporate document mistakes

Errors at incorporation follow through into accounting, tax and licensing.

  1. 1. Company objectives too narrow for the real business

    Why it matters: It affects licences, bank accounts and contracts.

    How to avoid it: Cover the next 2–3 years of business plans.

  2. 2. Shareholding structure ignoring sector restrictions

    Why it matters: Some sectors restrict foreign shareholding.

    How to avoid it: Check restrictions before designing the structure.

  3. 3. Loosely defined signing authority

    Why it matters: It creates risk or blocks transactions.

    How to avoid it: State signing conditions clearly in the affidavit.

  4. 4. Registered address without a consent letter

    Why it matters: Evidence of permission to use the premises is required.

    How to avoid it: Prepare the consent letter and property documents.

  5. 5. No plan for post-registration obligations

    Why it matters: Filings, tax and social security have fixed deadlines.

    How to avoid it: Set a compliance calendar from day one.

What the common mistakes actually cost

Almost every failure in legal instruments and drafting 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.

MistakeWhy it happensTime costHow to prevent it
Self-translating, or using a translator the destination does not recogniseSome countries accept only registered translators, others only translations certified by a Thai government body.Typically adds 4–10 working days for a fresh translation and a restarted chain.Ask the destination exactly which form of translation it accepts, then match the translator to that form from the start.
Planning without allowing for public and embassy holidaysEmbassies 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.
The name in the translation does not match the passport spellingReceiving 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 certificationThe 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.
Using an old copy instead of a freshly issued oneMany 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.

Most cases need more than one step. Here is how the surrounding work connects, so you can plan the whole chain instead of discovering a missing certification at the last minute.

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.

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

  • The name on an older document does not match the current passport because of a name change or a different transliteration.
  • 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.
  • Documents have a limited validity window and every item must still be valid on the day of filing.

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.
