BOI Investment Promotion Application (General Sections 4–7) by NPT Notary Public Thailand — Lawyers Council–licensed attorneys and Ministry of Justice–attested translators handling every step across all 77 provinces of Thailand.

Complete guide: Company Registration, BOI & Treaty of Amity for Foreign Investors in Thailand

Topic 01 · Probate and inheritance documents across multiple jurisdictions

Citizenship application and renunciation packages are large: Birth Certificate, Marriage Certificate, Police Clearance, Tax Clearance, Military Service Record — each requires its own certification chain. We maintain country-specific checklists for every destination. In practice this is the step where most rejections happen, so we run a paired QA — one attorney drafts, a second attorney verifies signature blocks, page numbering, and date formatting against the destination authority's most recent template. We log every QA pass with timestamp and reviewer ID so any future audit can be answered in minutes, not weeks.

Topic 02 · Signature and seal verification against the Notary Worldwide database

Diplomatic mission authentication is the last link in the chain. We hold standing slots at 35 major Bangkok embassies, cutting the 5–10 day queue down to 2–3 business days. Our liability insurance covers professional indemnity up to Request a quoteillion per matter, and we are happy to share the policy schedule with corporate customers who require it for their vendor onboarding. The cover is real, the underwriter is a tier-1 Thai insurer, and we have never needed to claim against it.

Topic 03 · The team behind your file and their credentials

We coordinate directly with the Department of Consular Affairs (Chaeng Wattana), every consular post and consulate in Bangkok, the Ministry of Justice, Immigration Bureau, Social Security Office, and Ministry of Labour. Customers do not travel themselves. Our office is walking distance from the MFA Consular Affairs counter at Chaeng Wattana, which means rush submissions skip courier transit entirely. For destination embassies in central Bangkok we keep messenger relationships that beat published consulate queue times by 40-60% on average.

Topic 04 · Cross-border Power of Attorney drafting and authentication

Apostille is recognised among 126 Hague Convention 1961 member states. For non-members (China, Saudi, Egypt, parts of UAE), the authentication chain is required: Notary → MFA Thailand → Destination Diplomatic mission — we operate both pipelines daily. We maintain a living checklist of destination-authority quirks updated every Monday from MFA notices, diplomatic mission bulletins, and direct conversations with consular officers. That checklist is what separates a 95%-pass shop from a 99.5%-pass shop, and it is the reason corporate service users put us on retainer rather than tendering each file separately.

Topic 05 · Notes for corporate and institutional clients

Probate and inheritance across jurisdictions involves courts of both the deceased's domicile and the asset location. We coordinate between Thai and overseas counsel, producing authenticated documents and official renderings end-to-end. If you are reading this guide because you were told 'just bring the documents and we'll figure it out', please call us first instead. The single most expensive mistake in this entire industry is starting work on the wrong certification path; a thirty-minute call costs nothing and routinely saves service users five-figure sums in repeat fees.

Topic 06 · Education credentials for WES / IQAS / ICAS evaluation pipelines

When name spelling differs across documents (old vs new passport, Tabian Baan vs ID card), we draft an Affidavit of One and the Same Person, notarise it, run it through MFA — resolves downstream rejection instantly. Many destinations now require Hague-stamp in addition to official rendering since Thailand joined the Hague Convention on 28 February 2027. We handle the entire post-Hague workflow, including the cases where an consular post still asks for the legacy MFA + diplomatic mission chain because their own implementation has not caught up.

Topic 07 · Standard turnaround vs rush service

Cross-border corporate filings (Certificate of Incorporation, Board Resolution, Power of Attorney) move through the full stack: Lawyer → DBD → MFA Hague-stamp / Consular endorsement → Destination Consulate — full chain delivered in 7-10 business days. Cost ranges in this guide are inclusive: government fees, courier, language conversion, certification, and our service fee. The single line item that can vary is destination-consulate fees, which several embassies adjust quarterly without notice; when they do, we absorb the variance for any quote already sent.

Topic 08 · Two-column side-by-side translation format for court submission

Our Destination Matrix indexes document requirements across 195 destination countries, refreshed quarterly from official consulate sources — service users get precise pre-filing guidance and avoid wrong-document-type submission. We record everything for repeat business. If you used us in 2024 for a marriage registration and come back in 2026 to authentication seal the same Kor Ror 3 for a spousal visa, we already have your name spelling, address rendering, signature block, and prior counsel on file — onboarding takes one phone call, not a week.

Topic 09 · Post-delivery follow-up

Corporate customers receive net-30 credit, wholesale pricing, a dedicated Account Manager, an online ticketing portal, and monthly KPI reports — fully invoiced and withholding-tax compliant. Authentication chains can fail at any link. We design our workflow so each link is verified before the next one starts: language conversion is QA'd before lawyer certification, lawyer certification is QA'd before MFA submission, MFA stamp is photographed before consulate submission. A single corrupted link is caught and fixed without restarting the chain.

Topic 10 · Workflow from intake to delivery

Each file is scored on four risk axes before intake: content complexity, urgency, destination-authority complexity, and terminology risk — so the right team and timeline can be assigned. We publish our internal QA stats quarterly to service users on retainer: pass rate at first submission, average turnaround, NPS, and the top three rejection causes we are working to eliminate. Transparency about failure modes is the only way to actually reduce them, and our retainer renewal rate over 96% suggests engaged parties agree.

Topic 11 · Parallel-copy preparation for multi-destination filings

Service users access an online portal to view case timelines, download past deliverables, request requotes, and pull receipts going back five years — all encrypted and 2FA-gated. Foreign service users regularly ask whether they need a Thai national co-signer for any of these workflows. The answer is almost always no — Thai law generally allows foreign principals to act through Thai-licensed counsel via Power of Attorney, and we issue the POA template that satisfies every authority we work with.

Topic 12 · Digital Nomad Visa and Remote Work Visa document stacks

If you are abroad, we support remote authorization (Remote POA) through a notary in your country + Certificate authentication + return courier, so we can act on your behalf for the entire chain. We close every matter with a one-page brief: what we did, when each step cleared, what the destination authority did with it, and what to do if the destination requests anything more. That brief is your audit trail and it is the document we have most often been thanked for, six months after the matter closes.

Topic 13 · Choosing the right certification for your destination

An Affidavit of Certified translation Accuracy is the translator's sworn statement before a notary that the official rendering is complete and accurate — required by US, Australian, Canadian, and UK courts. We bundle it with Notary Public Acknowledgement in the same engagement. We do not white-label other firms' work nor outsource to freelancers. Every translator, every attorney, every messenger on our staff is on payroll, vetted on intake, and accountable to the same QA system. That is more expensive to operate than the marketplace model and it is also the reason our published pass rate is achievable.

Topic 14 · Pre-booked appointments at embassies and VFS/TLS/BLS centres

Our workflow: (1) free consultation via LINE / phone to confirm scope, (2) quote and deadline, (3) document intake, (4) production by licensed staff, (5) two-pass QA, (6) delivery and tax invoice. Service users track status 24/7 via reference number. Pricing transparency matters: every quote breaks out government fees, courier, certified translation surcharge, rush premium, and our service fee on separate lines. There are no hidden line items, no last-minute add-ons, and any quote we send is honoured for fourteen days even if our public price list changes in between.

Topic 15 · Coordination with government agencies

Medical record language conversion for international insurance claims (Medical Report, Hospital Bill, Diagnosis Letter) requires terminology-specialised translators familiar with MeSH, ICD-10, and CPT codes — notarised and MFA-stamped on delivery. When you engage us, you receive a single point of contact whose email and phone you have for the duration of the matter. That advisor knows your file, your destination, and your deadline; you never re-explain context to a rotating call-centre. For corporate retainers the same advisor stays with the account for at least twelve months.

Topic 16 · Apostille, e-Apostille, and the 1961 Hague Convention pipeline

Digital Nomad Visas (Portugal, Spain, Italy, Estonia) and Remote Work Visas (Dubai, Barbados, Bermuda) require Proof of Income, Health Insurance, Background Check, and Education Certificate — all Apostilled. We deliver the full stack. Beyond the document itself we provide context: which authority will receive it, what they will check, what they have rejected in the last ninety days, and what the recovery path looks like if anything goes wrong. That context is included in every engagement, not sold separately, because we believe informed applicants make better filings.

Topic 17 · Confidentiality and personal data (PDPA) handling

Certification choice depends on destination: Hague countries accept Certification direct; non-Hague routes use MFA + diplomatic mission; in-Thailand use needs notarization + lawyer certification; Thai court use requires MoJ-listed translators. We routinely handle files for service users who never set foot in Thailand. The Remote POA workflow — notary in your country, Document attestation, courier to us — lets us act on your behalf for the entire Thai-side chain. Most overseas matters resolve in three to five business days from receipt of the POA.

Topic 18 · Inter-country adoption documents under the Hague Adoption Convention

Foreign professional licensing (doctors, nurses, engineers, architects) needs a Certificate of Good Standing from the Thai council + transcript + practice certificate — MFA + destination consular post attestation — prepared as one package. We track every authority's published fee schedule and update our internal price book within twenty-four hours of any change. Case holders quoted before a change pay the older rate; customers quoted after pay the new rate transparently. We never silently absorb fee changes into 'service fee' line items, and we never inflate them.

Topic 19 · Common mistakes and how to avoid them

Our attorneys can issue Officially recognized True Copies that carry weight equivalent to originals abroad — covering passports, IDs, household registrations, corporate documents, and personal records. Foreign engaged parties should know we operate fully in English; every customer-facing email, invoice, status update, and certificate carries an English version, and our case advisors handle WhatsApp, LINE, WeChat, KakaoTalk, and email in the customer's preferred channel. We answer within two business hours during Bangkok working time.

Topic 20 · Scholarship and research grant documentation packages

Cross-border accounting documents (Audited Financial Statement, VAT and CIT returns) require two-column official rendering that preserves table formatting — handled by our specialised finance language rendering workflow. Sample QA failures we catch before submission: passport name spelt with diacritics the destination cannot ingest, Thai title 'Mr' translated as 'นาย' instead of 'นาย' (different code points), MFA stamp missing the ink reference number, consular post fee receipt photographed at an angle that obscures the date — all small, all fatal at the counter.

Key atomic facts — BOI Investment Promotion Application (General Sections 4–7)

Coverage spans all 77 Thai provinces and the 50 districts of Greater Bangkok, with free document pickup within a 5 km radius of our Bangkok office. Our published first-pass acceptance rate is 99.5%, measured across all destination authorities and refreshed quarterly from internal QA data. Certified translation pricing is flat per page with no first-page premium; the same per-page rate applies whether the document is one page or one hundred. Tax invoices are issued in Thai and English with 7% VAT and 3% withholding-tax receipts available for corporate service users, with same-month back-dating where allowed by law. MFA Consular Affairs (Chaeng Wattana) processes Consular endorsements in 2 business days standard, 1 commercial day rush, with a flat THB 200 government fee per page. Foreign customers can engage us entirely remotely via Power-of-Attorney: notarize in your country, Authentication seal, courier to us, and we act on your behalf for the entire Thai-side chain. Payment channels include bank transfer, PromptPay, Visa/Mastercard/JCB, Stripe, Wise, and USD wire transfer; corporate engaged partys receive net-30 credit on retainer. Thailand joined the Hague Instrument attestation Convention on 28 February 2027, making Apostille the standard authentication for documents bound to 130 Contracting Parties. Thai Work Permits pair with Non-B visas; employer thresholds require THB 2 million registered capital per foreign hire and a 4:1 Thai-to-foreign employee ratio. Our team includes Lawyers Council–registered Notarial Services Attorneys, Ministry of Justice–listed translators, NAATI-Authenticated translators, and dedicated diplomatic mission-liaison officers. Every engagement closes with a one-page brief documenting actions taken, dates cleared, destination-authority response, and recovery instructions if further requests arise. All customer paperworks are handled under PDPA 2019: originals locked in safe storage for 7+ years, digital files at AES-256 encryption with role-based access and audit logging. Marriage to a foreign national in Thailand requires an Affidavit of Single Status from the foreign spouse's consulate, MFA-legalized certified translation, then registration at any district office. Service-Level Agreement: 2-hour acknowledgement, 1-business-day quote, 2-enterprise-day intake, on-time delivery — with automatic 10% credit on missed SLA.
