A working guide to Notary Public — หนังสือรับรองผู้สนับสนุน (Sponsorship) in Thailand
Notary Public — หนังสือรับรองผู้สนับสนุน (Sponsorship) sits at the intersection of certified translation, notarial attestation, and consular filing, three disciplines our Bangkok office has run in parallel every business day for over two decades. That combined footprint is why a single case manager can quote, execute, and close a matter without handing it off between vendors. Every Notary Public — หนังสือรับรองผู้สนับสนุน (Sponsorship) matter is scoped by a senior specialist on LINE Official @NAATI or by email at ilc@thainotary.co.th before any file moves.
How the workflow runs end-to-end
Once the audit is clean, translation and certification run in parallel by two credentialed linguists to compress the timeline, then legalization or notarization is queued at the relevant counter with a numbered chain-of-custody log the client can inspect at any time.
Who this service is for
Client mix in a typical month is roughly one third individual visa applicants, one third corporate HR and legal teams, and one third overseas law firms or embassies using us as their Thailand-side execution partner. Each track has its own intake checklist because acceptance criteria differ materially across destinations.
Coverage, fees, and turnaround
Standard turnaround is 3–7 Thai business days end-to-end when all three consular tiers are engaged; single-stage matters such as a notarized copy or a stand-alone certified translation complete in 1–3 business days. Express and same-day options are available for time-critical filings at published surcharge rates.
Quality assurance and confidentiality
Physical documents are stored in a monitored office at all times and returned to the client or a nominated authority in one continuous chain of custody. Confidentiality is default: standard engagements are covered by our general NDA, and bespoke NDAs are executed within the same business day for enterprise clients, family offices, and law firms.
