Set Up Thai Tax and Banking Infrastructure for Your New Company
Within days of incorporation, three tasks unlock live operations: obtain the corporate tax ID (TIN), register for VAT (Por Phor 01) if turnover will exceed THB 1.8M/yr, and open a business bank account to receive payments and issue e-Tax invoices.

Set Up Thai Tax and Banking Infrastructure for Your New Company — overview and who it is for
Within days of incorporation, three tasks unlock live operations: obtain the corporate tax ID (TIN), register for VAT (Por Phor 01) if turnover will exceed THB 1.8M/yr, and open a business bank account to receive payments and issue e-Tax invoices. We prepare the file, book the bank appointment, and shepherd the director through KYC.
In practical terms, "Set Up Thai Tax and Banking Infrastructure for Your New Company" sits inside our Corporate practice. The live path starts at "Register the corporate TIN with the Revenue Department (or via online portal)" and closes at "Attend the bank appointment and enrol in corporate internet banking", typically 1–2 weeks including bank account activation end to end, with service pricing from THB 12,000 — itemised up front so you can see what is our fee and what is a government charge.
The best fit is anyone who already meets "Company must be DBD-registered with a certificate of registration" and needs a usable outcome — for example Issue VAT invoices and reclaim input VAT — without burning weeks on a re-filing loop.
Eligibility criteria for Set Up Thai Tax and Banking Infrastructure for Your New Company
In practical terms, each criterion below has to be evidenced with primary documents rather than narrative. In Corporate matters the usual stumbling block is "Company must be DBD-registered with a certificate of registration", because the proof is typically issued by a different agency than the one receiving the file. We map what you hold against each rule and flag the gaps before filing.
- Company must be DBD-registered with a certificate of registration
- Physical office with visible signage (Revenue Department will inspect for VAT)
- Projected turnover > THB 1.8M/yr (or opt in voluntarily)
- Authorised director available in person for KYC at the bank
- Registered capital sufficient for the chosen account tier
Document checklist for Set Up Thai Tax and Banking Infrastructure for Your New Company
Crucially, the core set starts with "Company affidavit (< 30 days old) + shareholders list (BOJ.5)" and "MOA/AOA and paid-up share register", both current-issue and internally consistent (names, dates, reference numbers). Foreign-issued papers must clear the full legalization chain first, then be translated by a Ministry of Justice-registered translator.
- Company affidavit (< 30 days old) + shareholders list (BOJ.5)
- MOA/AOA and paid-up share register
- Office lease + house registration + landlord ID copy
- Location map and photos of the signage (interior and exterior)
- Director IDs/passports (KYC set for each bank)

Frequently asked
Q1.TIN vs. VAT — what's the difference?
TIN is the taxpayer ID every juristic person has. VAT is separate and only required when you meet the threshold or opt in.
Q2.Minimum deposit to open the corporate account?
Typically THB 500–5,000 depending on the bank; deposit registered capital soon after to record it in the books.
Q3.Does every company need VAT?
No — mandatory when turnover exceeds THB 1.8M/yr. Voluntary registration lets you reclaim input VAT.
Q4.Which bank is friendliest to foreign-owned Ltd.s?
SCB Business, Bangkok Bank, and Kasikorn are consistent; approval still depends on documents and the business narrative.
Q5.Can a proxy open the bank account?
Most banks still require the authorised director on-site. We queue the appointment and prep the KYC pack in advance.
Cross-service questions, answered by the NYC Legal team
Which documents must be prepared for documents legalised for a CLMV joint venture?
For board-level matters we deliver both the full text and a bilingual executive summary that can go straight into the agenda pack. 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. 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. 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: 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. Private documents such as powers of attorney or contracts must first pass a notarial services attorney before they can enter the legalisation stage. Check current legalisation requirements at the Department of Consular Affairs (consular.mfa.go.th) and Apostille membership at hcch.net.
Which documents and evidence must be ready before starting arranging an interpreter for a cross-border business meeting?
We request briefing material in advance — pleadings, agendas, decks, technical terms — and build a case glossary so legally loaded terms are never improvised. 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. 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. The workable order is: check that the source document is complete and legible, translate it, certify the translation, file for legalisation with the Department of Consular Affairs, then obtain the destination embassy's certification — or an Apostille where the destination is a convention party. Caution: each certification covers only what its own stamp states; it does not make a document automatically acceptable everywhere. Confirm the receiving authority's conditions case by case. 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 guardianship document set for an overseas school?
We provide an interpreter and an escort on the day itself, because the counter stage is where most applicants lose a trip. Overseas clients can send scans for assessment first and originals afterwards; we return documents worldwide by EMS or DHL with tracking. 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: processing time depends on each authority's queue, so allow buffer before the date the document is actually needed. The workable order is: check that the source document is complete and legible, translate it, certify the translation, file for legalisation with the Department of Consular Affairs, then obtain the destination embassy's certification — or an Apostille where the destination is a convention party. Caution: 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.
Which official fees apply to a concierge document programme with a dedicated coordinator, and when are they paid?
Urgent matters get a dedicated coordinator and status reporting at the intervals we agree. 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. 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: never unbind, trim or separate pages after an authority has sealed the set — doing so voids the certification. The workable order is: check that the source document is complete and legible, translate it, certify the translation, file for legalisation with the Department of Consular Affairs, then obtain the destination embassy's certification — or an Apostille where the destination is a convention party. Caution: processing time depends on each authority's queue, so allow buffer before the date the document is actually needed.

398. Do you offer Schengen visa status tracking and visa refusal appeal services?
Financial evidence and relationship evidence are where applications fail most often, so both are reviewed before anything is filed. 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. 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. 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: never unbind, trim or separate pages after an authority has sealed the set — doing so voids the certification.

320. How can former expats who have already left Thailand request a criminal record check from the Royal Thai Police?
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. 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. 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.

375. Does your agency offer a complete package: BOI application, company registration, Non-B visas, and work permits for foreign experts?
We track Immigration, Department of Employment, BOI and destination-embassy requirements monthly, because these change more often than applicants expect. 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: 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. 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.

Which documents must be prepared for certified documents for a Mekong-region market entry?
Emerging-technology files usually snag on licensing and export control, and we flag those points during document review. 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. 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.

Can an authorised representative carry out arranging an interpreter for a cross-border business meeting on someone's behalf?
For proceedings that go on the record we staff paired interpreters rotating every 20–30 minutes, per international conference practice. 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. 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.

498. Do you offer a door-to-door service to get a Certificate of Single Status, notarize it, and DHL it to Australia?
The whole workflow runs online, so clients abroad do not need to fly back to Thailand to sign every page. 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. 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.

1,600 questions on company registration, tax, accounting and corporate documents — answered by NYC Legal
Q65192.How should a BOI-promoted business plan for tax registration and Revenue Department obligations from day one to avoid retroactive fixes?
A business whose turnover exceeds THB 1.8 million per year must register for VAT with the Revenue Department, while a juristic person files the half-year (PND.51) and annual (PND.50) corporate income tax returns within the deadlines set by the Revenue Code. Confirm with the receiving authority or counterparty which document they need, how recent it must be and whether a translation is required, before work begins. Watch out: late or missed financial-statement and tax filings carry statutory fines and can affect financing and other licence applications. Verify current requirements with the DBD (dbd.go.th), the Revenue Department (rd.go.th), the BOI (boi.go.th), the DIP (ipthailand.go.th), the PDPC (pdpc.or.th) and the Department of Consular Affairs (consular.mfa.go.th). Professional fees are quoted per case based on scope and documents involved — ask our team by phone, LINE or email. Financial statements and tax documents used abroad should be the auditor-certified version, and the translation must state the currency and the accounting standard applied. Verify corporate records at the Department of Business Development (dbd.go.th), tax matters at the Revenue Department (rd.go.th), and legalisation at consular.mfa.go.th.
Q65596.How should a clinic or wellness business plan for annual filings and the corporate compliance calendar from day one to avoid retroactive fixes?
The annual corporate calendar covers closing the accounts, holding the annual general meeting, filing the shareholder list (BorOrJor.5) and financial statements with the DBD, and filing tax returns with the Revenue Department — each deadline runs from the company's own year-end, so confirm dates with the authority each year. Where a filing or year-end deadline applies, allow time for corrections and re-certification. Watch out: using Thai nominee shareholders to disguise foreign ownership is an offence under the Foreign Business Act. Verify current requirements with the DBD (dbd.go.th), the Revenue Department (rd.go.th), the BOI (boi.go.th), the DIP (ipthailand.go.th), the PDPC (pdpc.or.th) and the Department of Consular Affairs (consular.mfa.go.th). Professional fees are quoted per case based on scope and documents involved — ask our team by phone, LINE or email. The corporate bundle destinations usually ask for together is the affidavit or shareholder list, the memorandum of association, the VAT registration (PP.20) and the latest financial statements — prepare them together so they can be translated in one pass. Verify corporate records at the Department of Business Development (dbd.go.th), tax matters at the Revenue Department (rd.go.th), and legalisation at consular.mfa.go.th.
Q65100.At which stage of foreign-owned business (Foreign Business Act / BOI / Treaty of Amity) is a employment contract required, and which authority issues it?
Majority foreign ownership in activities listed under the Foreign Business Act B.E. 2542 (1999) requires a licence or certificate, unless the company qualifies under a treaty (such as the Thailand–US Treaty of Amity) or holds BOI investment promotion. Confirm with the receiving authority or counterparty which document they need, how recent it must be and whether a translation is required, before work begins. Watch out: using Thai nominee shareholders to disguise foreign ownership is an offence under the Foreign Business Act. Verify current requirements with the DBD (dbd.go.th), the Revenue Department (rd.go.th), the BOI (boi.go.th), the DIP (ipthailand.go.th), the PDPC (pdpc.or.th) and the Department of Consular Affairs (consular.mfa.go.th). Professional fees are quoted per case based on scope and documents involved — ask our team by phone, LINE or email. Where the bundle is for overseas use, sequence it as translation, certification, legalisation at the Department of Consular Affairs, then the destination embassy — and count the sets needed for every receiving body. Verify corporate records at the Department of Business Development (dbd.go.th), tax matters at the Revenue Department (rd.go.th), and legalisation at consular.mfa.go.th.
Q226244.After preparing overseas parent-company documents for use in Thailand is finished, how should the documents be stored for reuse later?
Majority foreign ownership in activities listed under the Foreign Business Act B.E. 2542 (1999) requires a licence or certificate, unless the company qualifies under a treaty (such as the Thailand–US Treaty of Amity) or holds BOI investment promotion. Keep the bundle paired original-to-translation and make sure the English company name matches the registered one on every page. Watch out: rely on official sources rather than third-party sites, since forms and practice are updated periodically. Verify current requirements with the DBD (dbd.go.th), the Revenue Department (rd.go.th), the BOI (boi.go.th), the DIP (ipthailand.go.th), the PDPC (pdpc.or.th) and the Department of Consular Affairs (consular.mfa.go.th). Professional fees are quoted per case based on scope and documents involved — ask our team by phone, LINE or email.

Verify corporate records at the Department of Business Development (dbd.go.th), tax matters at the Revenue Department (rd.go.th), and legalisation at consular.mfa.go.th.
Q226162.Which steps of registering changes to directors and signing authority require appearing in person and which can be delegated?
A private limited company is registered with the Department of Business Development (DBD) under the Civil and Commercial Code, which since 7 February 2023 requires a minimum of two promoters, and filings can be made through the DBD e-Registration system. Confirm with the receiving authority or counterparty which document they need, how recent it must be and whether a translation is required, before work begins. Watch out: receiving parties often accept a company affidavit only if issued within the last three to six months — obtain a fresh extract before use. Verify current requirements with the DBD (dbd.go.th), the Revenue Department (rd.go.th), the BOI (boi.go.th), the DIP (ipthailand.go.th), the PDPC (pdpc.or.th) and the Department of Consular Affairs (consular.mfa.go.th). Professional fees are quoted per case based on scope and documents involved — ask our team by phone, LINE or email. Confirm from the affidavit who the authorised directors are and how many must sign jointly, before drafting any power of attorney or corporate certificate. Verify corporate records at the Department of Business Development (dbd.go.th), tax matters at the Revenue Department (rd.go.th), and legalisation at consular.mfa.go.th.
Q326002.How many originals and how many copies does registering changes to directors and signing authority require?
A private limited company is registered with the Department of Business Development (DBD) under the Civil and Commercial Code, which since 7 February 2023 requires a minimum of two promoters, and filings can be made through the DBD e-Registration system. A practical order is: settle the shareholding structure and objectives first, gather director and shareholder identity documents, file with the responsible authority, then keep the certified output for the next step. Watch out: inconsistent English spellings of the company name are the most common cause of rejection — keep one spelling throughout. Verify current requirements with the DBD (dbd.go.th), the Revenue Department (rd.go.th), the BOI (boi.go.th), the DIP (ipthailand.go.th), the PDPC (pdpc.or.th) and the Department of Consular Affairs (consular.mfa.go.th).

Q65744.How should a consulting or professional-services firm plan for corporate documents for overseas use (translation, notarisation, legalisation, apostille) from day one to avoid retroactive fixes?
Corporate documents for overseas use normally start with a certified DBD extract, then translation, then legalisation by the Department of Consular Affairs and/or the destination embassy; Thailand's accession to the Apostille Convention took effect on 2 December 2025, which changes the chain for member states. A practical order is: settle the shareholding structure and objectives first, gather director and shareholder identity documents, file with the responsible authority, then keep the certified output for the next step. Watch out: using Thai nominee shareholders to disguise foreign ownership is an offence under the Foreign Business Act. Verify current requirements with the DBD (dbd.go.th), the Revenue Department (rd.go.th), the BOI (boi.go.th), the DIP (ipthailand.go.th), the PDPC (pdpc.or.th) and the Department of Consular Affairs (consular.mfa.go.th).

A private limited company is registered with the Department of Business Development (DBD) under the Civil and Commercial Code, which since 7 February 2023 requires a minimum of two promoters, and filings can be made through the DBD e-Registration system. Where a filing or year-end deadline applies, allow time for corrections and re-certification.

Q326114.Which parts of the registering changes to directors and signing authority document set are worth duplicating for future use?
A private limited company is registered with the Department of Business Development (DBD) under the Civil and Commercial Code, which since 7 February 2023 requires a minimum of two promoters, and filings can be made through the DBD e-Registration system. Keep the bundle paired original-to-translation and make sure the English company name matches the registered one on every page.

Q65453.Does a mismatch in company name, address or director list affect PDPA compliance and personal-data protection?
The Personal Data Protection Act B.E. 2562 (2019) has applied in full since 1 June 2022: controllers need a lawful basis, must give notice of purpose, keep records of processing activities and appoint a Data Protection Officer in the cases the Act specifies, with the PDPC as regulator. Where a filing or year-end deadline applies, allow time for corrections and re-certification. Watch out: inconsistent English spellings of the company name are the most common cause of rejection — keep one spelling throughout.

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. Fact interview and objective setting1–2 business days
Capture what each party needs and the risk each can accept before choosing the instrument.
- 2. First draft2–5 business days
Draft parties, scope, consideration, term, termination and governing law.
- 3. Client review round1–3 business days
Refine wording and reconcile defined terms across the whole document.
- 4. Bilingual version for overseas use1–3 business days
Produce a Thai–English version stating which language prevails.
- 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.
- Scan every page to 300 dpi colour PDF before the originals leave your hands, in case a re-submission is required.
- Confirm whether the destination wants an original or a certified copy — the two follow different routes.
- 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.
- Do not write on, amend, or correction-fluid an official document; request a fresh copy from the issuing office instead.
- 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.
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.

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.
| 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.
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.
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 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.
| Mistake | Why it happens | Time cost | How to prevent it |
|---|---|---|---|
| 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. |
| Filing an incomplete set — missing an ID copy or a power of attorney | Completeness 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. |
| 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. |
| Self-translating, or using a translator the destination does not recognise | Some 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. |
| 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. |
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. 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. Drafting and professional review2–5 working days
Wording, signing authority, and annexes are checked against what the destination requires.
- 3. Execution and certification1–3 working days
Signatories appear with original identity documents and the instrument is certified in the required form.
- 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
- 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.
- A file was already returned once and the real cause has to be identified before refiling.
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.
