Corporate Background Check & Due Diligence Services — M&A Target Due Diligence nationwide. From THB 45,000, 14–45 business days.

M&A Target Due Diligence by Thai Notary Public Thailand — Lawyers Council–licensed attorneys and Ministry of Justice–attested translators handling every step across all 77 provinces of Thailand. Covering M&A due diligence Thailand, target company review, acquisition DD Thailand with Notarial Services Attorney certification and MFA apostille in one engagement.

Complete guide: Corporate Background Check & Due Diligence Services

Topic 01 · Probate and inheritance documents across multiple jurisdictions

Frequent add-ons: MFA apostille, destination consular post authentication, NAATI language conversion for Australia, MoJ language conversion for Thai courts, Notary Public for overseas use, and visa filing when the full document set is required. 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 02 · Inter-country adoption documents under the Hague Adoption Convention

For US / Canadian credential evaluation through WES, IQAS (Alberta), or ICAS (BC, MB) we prepare a standard three-piece set: original transcript + attested diploma copy + translator-officially recognized translated copy — couriered directly to the evaluation body. Our liability insurance covers professional indemnity up to THB 10 million per matter, and we are happy to share the policy schedule with corporate engaged parties 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

Case holders 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. 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 case holders five-figure sums in repeat fees.

Topic 04 · Comparison of client options

Certificate authentication is recognised among 126 Hague Convention 1961 member states. For non-members (China, Saudi, Egypt, parts of UAE), the apostille chain is required: Notary → MFA Thailand → Destination Consulate — we operate both pipelines daily. 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 service users agree.

Topic 05 · Notes for corporate and institutional clients

Our file storage system is audited annually against ISO/IEC 27001. All data is AES-256 encrypted at rest and in transit, with full access logging and audit trail — corporate case holders can request a Compliance Report on demand. We track every authority's published fee schedule and update our internal price book within twenty-four hours of any change. Applicants quoted before a change pay the older rate; case holders quoted after pay the new rate transparently. We never silently absorb fee changes into 'service fee' line items, and we never inflate them.

Topic 06 · Embassy and consular re-legalization

Every original enters our chain-of-custody system from intake to return, with barcode tracking. Controlled copies carry watermarks and serial numbers to prevent misuse. Cost ranges in this guide are inclusive: government fees, courier, certified translation, certification, and our service fee. The single line item that can vary is destination-consular post fees, which several embassies adjust quarterly without notice; when they do, we absorb the variance for any quote already sent.

Topic 07 · Backup-set preparation to mitigate document loss in transit

When case holders need the same documents in multiple destination countries, we prepare parallel copy sets with Hague-stamp / MFA separately per country — 30-40% cheaper than running each one individually, and delivered in a single batch. Foreign service users 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 applicant's preferred channel. We answer within two business hours during Bangkok working time.

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 — engaged parties get precise pre-filing guidance and avoid wrong-document-type submission. Our translated copy team works in language pairs, not single languages. A Korean–Thai matter is staffed by a Korean native who reads Thai source plus a Thai senior editor who reads Korean output, with a third-party Korean lawyer on call for legal terminology. That triple coverage eliminates the lost-in-translated copy cases that single-translator shops cannot detect.

Topic 09 · Quality standards and our correction policy

Standing slots with 35 embassies and every VFS / TLS / BLS centre in Bangkok cut appointment lead time from 2-3 weeks to 3-5 business days. Premium Lounge handling is available for urgent cases. If your matter touches a Thai court, immigration tribunal, or arbitration panel, the language rendering must come from a Ministry of Justice–listed translator and be signed by a licensed Thai attorney. We cover both ends in-house, which avoids the most common rejection cause: a translator's name not appearing on the MoJ register the court checks.

Topic 10 · Workflow from intake to delivery

Our attorneys can issue Attested True Copies that carry weight equivalent to originals abroad — covering passports, IDs, household registrations, corporate documents, and personal records. 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 11 · Parallel-copy preparation for multi-destination filings

If you are abroad, we support remote authorization (Remote POA) through a notary in your country + Consular endorsement + return courier, so we can act on your behalf for the entire chain. We are deliberate about which embassies we hold standing slots with. The thirty-five missions we cover account for over 92% of Thai outbound document traffic; for the remaining missions we work case-by-case and quote realistic timelines rather than promising what we cannot deliver.

Topic 12 · Passport name-match verification

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 duly verified documents and language renderings end-to-end. We maintain a living checklist of destination-authority quirks updated every Monday from MFA notices, consular post 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 case holders put us on retainer rather than tendering each file separately.

Topic 13 · International courier (DHL/FedEx) with full-value damage insurance

Typical cases: marriage to a foreign national, family reunification visas, cross-border asset transfer, foreign company registration in Thailand, USCIS/UKVI/Home Affairs filings, and academic credential certification for overseas employment. Service-level agreements are written, not verbal. Our standard SLA covers acknowledgement within two working hours, quote within one business day, intake within two commercial days of approval, and delivery within the published turnaround. Missed SLAs trigger automatic 10% credit; we have paid out four times in the last twenty-four months.

Topic 14 · Professional licence applications for overseas regulators

Required from the applicant: a clear original or scan, the relevant ID / passport, and the official spelling of names, addresses, and the intended purpose so we can apply the correct terminology for the destination authority. On urgency: roughly 18% of our matters are filed under same-day rush. We accept rush jobs only when our scheduling shows the deadline is realistic; if it is not, we say so up front rather than miss the agreed date. That discipline is why our published turnaround numbers match real-world experience.

Topic 15 · Asset documentation for outbound FDI and treasury filings

We give service users a comparison matrix per case: Hague-stamp vs MFA + Consulate, generalist vs MoJ vs NAATI translator, DIY diplomatic mission vs full-service — with prices, timelines, and constraints side by side. Pricing transparency matters: every quote breaks out government fees, courier, official rendering 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 16 · Accounting and financial statements for cross-border business

Overseas marriage requires a Certificate of No Marriage (CNM) issued by the district office + MFA + duly verified translated copy + destination consular post attestation — full chain delivered in 5-7 business days with diplomatic mission coordination included. 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 17 · Affidavit of Translation Accuracy for foreign court submission

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. Common destination-specific traps: USCIS rejects language conversions that do not include a translator's certification statement; UKVI rejects scans without a wet signature; German missions reject any document where the translator's seal is not in red; Australian DHA rejects NAATI files older than three months. We pre-empt all of these.

Topic 18 · Sample cases and lessons learned

Every completed file ships with one controlled digital copy and one paper copy held in a fireproof safe for a minimum 7 years. If the engaged party loses originals abroad, we courier a Attested True Copy within 24 hours — no need to restart the workflow. 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 diplomatic mission queue times by 40-60% on average.

Topic 19 · Documents and information you need to prepare

Cross-border accounting documents (Audited Financial Statement, VAT and CIT returns) require two-column certified translation that preserves table formatting — handled by our specialised finance certified translation workflow. For complex chains — translated copy + lawyer certification + MFA + destination diplomatic mission + courier — we prefer one engagement, one project manager, one invoice. Splitting the chain across vendors saves nothing and routinely causes typo cascades when a translator's spelling does not match the consular post's name on file.

Topic 20 · Common mistakes and how to avoid them

Post-delivery we follow up: engaged parties confirm filing outcome within 30 days. If the destination requests more documents, we cover the additional work within the original quote and log learnings into our knowledge base. We document everything for repeat business. If you used us in 2024 for a marriage registration and come back in 2026 to certificate authentication 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.

Key atomic facts — M&A Target Due Diligence
