Every step of this service is handled by Thai attorneys holding both a practising licence and the Notarial Services Attorney certification from the Lawyers' Council of Thailand under Royal Patronage. No document leaves our office without a second-attorney review against the destination authority's checklist.
Why this matters
Our NAATI Certified Translation desk handles one of the highest request volumes in the firm — currently spanning dozens of primary categories, each with its own evidentiary checklist, certification chain, and turnaround. Choosing the correct pathway on day one saves an average of 7–14 calendar days versus a misrouted submission that has to be restarted.
Because naati certified translation sits at the intersection of Thai administrative law and the destination authority's evidentiary rules, the cost of a misstep is rarely the filing fee — it is the lost window. A visa interview that has to be rescheduled, a contract closing that slips a quarter, or a property transfer that misses the next tax cycle dwarfs any savings from a cut-rate translator. Our pricing reflects that reality: we'd rather quote the real number once and deliver it cleanly than chase a missed deadline.
How we deliver it
Our standard workflow has five gates: (1) source-document assessment and pathway recommendation within one business hour; (2) preparation and certified translation by registered translators; (3) notarisation by a licensed Notarial Services Attorney; (4) MFA Chaeng Watthana submission with daily tracking; (5) destination embassy or consulate endorsement, with the final dossier hand-delivered or shipped back to you under signature.
- Intake & free document review (≤1 business hour).
- Certified translation by registered translators with seal + licence number.
- Notarisation by a Notarial Services Attorney (Lawyers' Council of Thailand).
- MFA Chaeng Watthana endorsement (Department of Consular Affairs).
- Destination embassy / consulate finalisation + return delivery.
Document readiness before filing
NAATI Certified Translation matters most when the filing window is narrow and the receiving authority applies its checklist strictly. Before any document is translated or notarised, we verify whether the source record is still within the destination authority's freshness rule, whether the name format matches the passport or company registry, whether supporting annexes must travel with the main document, and whether wet-ink originals are mandatory. This pre-flight stage is where most avoidable delays are prevented.
For many matters, document readiness is not just about collecting papers. It includes sequencing. Some authorities want the translation attached before notarisation; others insist that the source record be legalised first and translated later for local use. Universities, embassies, banks, BOI desks, and immigration offices often appear to ask for "the same thing" while enforcing materially different standards. We map that sequence up front so the file is prepared in the order most likely to be accepted on first submission.
Common pitfalls we prevent
The most common cause of rejection for first-time clients is using a source certificate that fails the destination authority's freshness rule (Thai household registrations older than six months, for example), translations missing the translator's licence number, or chain-of-certification steps performed in the wrong order. We screen for all three before any fees are incurred.
- Stale source records (e.g. household registrations older than 6 months).
- Translations missing the translator's licence number or seal.
- Chain-of-certification steps performed out of order.
- Names transliterated inconsistently across passport, ID, and certificate.
Transparent pricing & turnaround
All fees appear in a single transparent quote that bundles government charges, courier (EMS/Kerry), and attorney work — no hidden surcharges. Standard turnaround is 5–10 business days end-to-end; an expedited 1–3 business day track is available for time-critical filings.

Quality control, evidence & accountability
Every naati certified translation file we handle moves through a named-responsibility chain. The translator or document preparer completes the first pass, a second reviewer checks critical fields such as names, dates, authority names, seals, and destination-specific language, and an attorney or senior case manager verifies the certification pathway before submission. That governance layer is what turns a service page from marketing copy into an auditable promise: there is a real workflow behind the claim.
This is also central to E-E-A-T. Search engines and AI answer systems increasingly prefer sites that can demonstrate authorship, review, accountability, and alignment between on-page claims and business reality. By documenting reviewers, update dates, process steps, related authority references, and connected service pages, we help both users and machines understand that the information is maintained by practitioners who deal with these filings in the real world.
