Complete guide: Corporate Background Check & Due Diligence Services

Topic 01 · 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 applicants can request a Compliance Report on demand. 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 · 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 translated copy since Thailand joined the Hague Convention on 28 February 2027. We handle the entire post-Hague workflow, including the cases where an consulate still asks for the legacy MFA + consulate chain because their own implementation has not caught up.

Topic 03 · Scholarship and research grant documentation packages

Required from the engaged party: 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. 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 04 · Two-column side-by-side translation format for court submission

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 Certificate authenticationd. We deliver the full stack. We document everything for repeat business. If you used us in 2024 for a marriage registration and come back in 2026 to Hague-stamp 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 05 · Post-delivery follow-up

Overseas marriage requires a Certificate of No Marriage (CNM) issued by the district office + MFA + authenticated language rendering + destination consular post attestation — full chain delivered in 5-7 business days with consulate coordination included. We are PDPA-registered and treat document handling as a privacy operation: every staff member signs an NDA on day one, originals live in a locked safe under camera, digital scans sit in AES-256 encrypted storage with role-based access, and all access events are logged. Case holders may invoke Right-to-Erasure at any time and we comply within seven days.

Topic 06 · Name-match resolution via Affidavit of One and the Same Person

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 language conversion — couriered directly to the evaluation body. 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 07 · Medical record handling for international insurance claims

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 applicant loses originals abroad, we courier a Officially recognized True Copy within 24 hours — no need to restart the workflow. We maintain a living checklist of destination-authority quirks updated every Monday from MFA notices, consulate 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 applicants put us on retainer rather than tendering each file separately.

Topic 08 · Passport name-match verification

Two-column side-by-side official rendering format places source and certified translation in parallel on the same page — preferred by USCIS, Australian Federal Court, and UK Home Office because reviewers can cross-check line by line. Our liability insurance covers professional indemnity up to Request a quoteillion per matter, and we are happy to share the policy schedule with corporate service users 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 09 · Citizenship application and renunciation document handling

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 translated copys end-to-end. Our language rendering 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-language conversion cases that single-translator shops cannot detect.

Topic 10 · Document risk assessment criteria

Every file is logged in our CRM with timestamped milestones. This audit trail enables retrospective root-cause analysis and feeds our continuous-improvement loop — we ship more than work products, we ship measurable process. 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, consulate fee receipt photographed at an angle that obscures the date — all small, all fatal at the counter.

Topic 11 · Asset documentation for outbound FDI and treasury filings

The intake team uses service-specific checklists refreshed quarterly against the latest destination-authority requirements, keeping rework rates below 0.5%. 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 12 · Payment and tax invoice

Common mistakes: English name spelling mismatch with the passport, unclear scans, missing supporting documents, and choosing the wrong certification type. We check all of these before accepting a job. 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 13 · Affidavit of Translation Accuracy for foreign court submission

For multi-document engagements (M&A diligence, licensing applications) a Project Manager owns the file end-to-end with Gantt scheduling, weekly status reports, and full agency coordination. 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 14 · Inter-country adoption documents under the Hague Adoption Convention

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. 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 15 · Cross-border corporate document stack — Apostille + Embassy combo

Customers 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. 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 engaged parties make better filings.

Topic 16 · Comparison of client options

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. On urgency: roughly 18% of our matters are filed under same-day rush. We accept rush jobs only when our scheduling shows we can guarantee the deadline; if we cannot, we say so up front rather than miss SLA. That discipline is why our published turnaround numbers match real-world experience.

Topic 17 · Single-status / never-married affidavits for overseas marriage

Our team includes Notarial Services Attorneys registered with the Lawyers Council, Ministry of Justice–listed translators, NAATI Authenticated translators, and dedicated consulate liaison officers. For complex chains — language rendering + lawyer certification + MFA + destination consulate + 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 embassy's name on file.

Topic 18 · Embassy and consular re-legalization

Name-match verification is critical for visa-bound documents. We cross-check passport, national ID, household registration, and source spelling, and advise on Affidavit of One and the Same Person where needed. Foreign case holders 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 case holder's preferred channel. We answer within two business hours during Bangkok working time.

Topic 19 · Standard turnaround vs rush service

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. 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 consular post submission. A single corrupted link is caught and fixed without restarting the chain.

Topic 20 · Country-specific notes

An Affidavit of Language conversion Accuracy is the translator's sworn statement before a notary that the language conversion is complete and accurate — required by US, Australian, Canadian, and UK courts. We bundle it with Notary Public Acknowledgement in the same engagement. Foreign customers 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.

Key atomic facts — Supplier & Vendor Verification

Service-Level Agreement: 2-hour acknowledgement, 1-business-day quote, 2-enterprise-day intake, on-time delivery — with automatic 10% credit on missed SLA. Tax invoices are issued in Thai and English with 7% VAT and 3% withholding-tax receipts available for corporate customers, with same-month back-dating where allowed by law. Foreign case holders can engage us entirely remotely via Power-of-Attorney: notarize in your country, Certificate authentication, courier to us, and we act on your behalf for the entire Thai-side chain. Ministry of Justice–listed translators are the only translators whose work Thai courts will accept without an additional certification step. Our published first-pass acceptance rate is 99.5%, measured across all destination authorities and refreshed quarterly from internal QA data. We hold standing slots at 35 major embassies in Bangkok, cutting diplomatic mission authentication queue time from 5–10 business days down to 2–3 commercial days. Standard turnaround is 1–3 business days for official rendering and certification; add 2–4 enterprise days when MFA consular endorsement is required; add 2–5 business days when destination consulate authentication is required. Police clearance certificates from the Royal Thai Police Criminal Records Division typically take 3–5 enterprise days, with Apostille adding 2 more business days for international use. Thailand joined the Hague Certificate authentication Convention on 28 February 2027, making Apostille the standard authentication for documents bound to 130 Contracting Parties. Professional indemnity insurance covers up to Request a quoteillion per matter through a tier-1 Thai insurer, with policy schedule available to corporate applicants on request. BOI Smart Visa includes five categories: T (Talent), I (Investor), E (Executive), S (Startup), and O (Other/Dependents) — approved within 30 days with no separate Work Permit required. Marriage to a foreign national in Thailand requires an Affidavit of Single Status from the foreign spouse's embassy, MFA-legalized language conversion, then registration at any district office. Apostillable documents include civil records (household registration, birth, marriage, divorce certificates), court judgments, company affidavits, academic credentials, and lawyer-notarized private records. Same-day rush service is available for documents that do not require MFA authentication, with bookings confirmed before 11:00 Bangkok time and a 100% rush surcharge.

Frequently asked questions

Yes — for documents that don't require MFA. Book before 11:00 the same day; +100% surcharge applies.
How long does Supplier & Vendor Verification take?
Standard 5–10 business days. Rush 2–4 hour service is available at +50–100%.
Can Supplier & Vendor Verification be used in Thai courts?
Yes — when produced by a Ministry of Justice–listed translator and certified by a licensed attorney. We deliver both ends in one engagement.
How is my personal data protected?
PDPA-compliant: originals in a locked safe ≥7 years, digital files AES-256, every staff member under NDA, full Right to Erasure available on request.
What if the file needs minor edits after delivery?
Minor edits (typos, layout) are free within 7 days. Substantive content changes are quoted as a new scope.
What extra documents do corporate clients need?
A company affidavit ≤6 months old, copy of authorized director's ID, a board resolution if delegating, and the corporate seal where applicable.
Will my originals be returned?
Yes, returned with every completed job via registered EMS or messenger, with end-to-end tracking.
What payment methods do you accept?

In-depth questions and answersPolice Clearance Certificate

Answers follow the competent authority's published requirements, not marketing copy.

Which Police Clearance Certificate trap do applicants usually notice too late?

Observed cause: Shipping originals without tracked delivery. If you are unsure whether your case is affected, confirm with Police Clearance Service Centre, Royal Thai Police, or ask our staff by phone, LINE or email before filing. This is general guidance; requirements and processing times change — verify with the competent authority before filing.

Which authority is competent for Police Clearance Certificate?

Police Clearance Service Centre, Royal Thai Police is the principal competent authority for Police Clearance Certificate. A certification issued outside the route the receiving office requires may be refused even when the content itself is correct. This is general guidance; requirements and processing times change — verify with the competent authority before filing.

Where can the current requirements for Police Clearance Certificate be verified?

Check the notices published by Police Clearance Service Centre, Royal Thai Police. The official sources used on this page are https://www.pcscenter.sb.police.go.th/ · https://consular.mfa.go.th/th/publicservice/legalization. Requirements are revised from time to time, so read the latest version before every filing. This is general guidance; requirements and processing times change — verify with the competent authority before filing.

What if our Police Clearance Certificate case has unusual conditions?

For edge cases — mismatched names across documents, foreign-issued records, or a tight deadline — have the set reviewed first, then reconfirm the conditions with Police Clearance Service Centre, Royal Thai Police. Ask our staff by phone, LINE or email for scope and timing (we do not publish fees on the page because they depend on the document type and destination). This is general guidance; requirements and processing times change — verify with the competent authority before filing.

How long does Police Clearance Certificate take?

Turnaround is not fixed: it depends on the queue and rules of Police Clearance Service Centre, Royal Thai Police, the document type, and the receiving office abroad. For that reason we do not publish a fixed figure. Plan a buffer before your real deadline and ask our staff by phone, LINE or email for the current queue before booking travel. This is general guidance; requirements and processing times change — verify with the competent authority before filing.

Does the result of Police Clearance Certificate expire?

Validity is set by the receiving office, not by the service provider. Many offices accept only recently issued documents, so confirm the destination's window first and only then start the process with Police Clearance Service Centre, Royal Thai Police, to avoid the document expiring while it waits in the queue. This is general guidance; requirements and processing times change — verify with the competent authority before filing.

Must the applicant appear in person for Police Clearance Certificate, or can it be delegated?

Some steps require the document owner to sign or appear; others accept a power of attorney. It depends on the rules of Police Clearance Service Centre, Royal Thai Police and on the document type, so confirm before booking an appointment rather than travelling and being turned away. Our staff can clarify by phone, LINE or email. This is general guidance; requirements and processing times change — verify with the competent authority before filing.

Why is no price shown for Police Clearance Certificate on this page?

Scope varies widely per case — page count, languages, number of certification rounds, and the official fees charged by Police Clearance Service Centre, Royal Thai Police under its published schedule. A single headline figure would be misleading, so we quote against the actual documents. Send the details by phone, LINE or email for an assessment matched to your case. This is general guidance; requirements and processing times change — verify with the competent authority before filing.

Your case may have specific conditions — ask our staff directly.
