| Step | Performed by | Documents needed | Approximate time |
|---|---|---|---|
| 1. Confirm the certification format the receiving body requires | Applicant + receiving authority | Published requirements or the authority's written reply | approx. 1 day |
| 2. Translate and proofread names, numbers and legal terms | Translator and reviser | Legible original + passport copy | approx. 1–3 working days |
| 3. Issue the certificate of translation accuracy | Translator or Notarial Services Attorney, as required | Finished translation | approx. 1 working day |
| 4. Legalization or Apostille for overseas use | Department of Consular Affairs, MFA | Original + certified translation | approx. 2–7 working days |
Durations are estimates and depend on the responsible authority's queue. Always confirm current requirements with the receiving body before filing.
Interpreting appointments at Thai government offices usually hinge on paperwork certified beforehand — typically a notarised power of attorney plus the certified translations quoted during the session. Preparing both in advance avoids a second appointment.

Observed cause: Not verifying with the registrar how many interpreters and witnesses are required. If you are unsure whether your case is affected, confirm with Courts of Justice, Department of Provincial Administration, or the convening body, 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.
Observed cause: Venues with echo or no sound system, degrading output quality. If you are unsure whether your case is affected, confirm with Courts of Justice, Department of Provincial Administration, or the convening body, 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.
Observed cause: Expecting legal advice from the interpreter, which is outside their role. If you are unsure whether your case is affected, confirm with Courts of Justice, Department of Provincial Administration, or the convening body, 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.
Courts of Justice, Department of Provincial Administration, or the convening body is the principal competent authority for Professional interpreting. 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.
Check the notices published by Courts of Justice, Department of Provincial Administration, or the convening body. The official sources used on this page are https://www.coj.go.th/ · https://www.dopa.go.th/. 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.
For edge cases — mismatched names across documents, foreign-issued records, or a tight deadline — have the set reviewed first, then reconfirm the conditions with Courts of Justice, Department of Provincial Administration, or the convening body. 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.
Turnaround is not fixed: it depends on the queue and rules of Courts of Justice, Department of Provincial Administration, or the convening body, 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.
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 Courts of Justice, Department of Provincial Administration, or the convening body, 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.
Your case may have specific conditions — ask our staff directly.
