Professional interpreter working in a legal setting

How to choose court interpreters and litigation document support

Quick answer

Thai court proceedings are conducted in Thai, and the court may order a Thai translation of any foreign-language document submitted in evidence. Where a party or witness does not understand Thai, the court arranges an interpreter, who takes an oath before acting. Verifiable criteria: experience in the same case type, a translation that renders seals and signatures in full, and a clearly named person accountable for the translation.

The sequence published by the authorities

  1. Confirm with the receiving authority which document, which language, and which layers of certification it requires.
  2. Collect originals certified by the issuing office, including every page that carries an entry.
  3. Reconcile names, dates of birth and document numbers across all documents before translation starts.
  4. Translate and have the responsible person sign the certification in the format the destination requires.
  5. File in the order published by the authority and keep each filing receipt so status can be traced.

Translating documentary evidence for court filing

A translation filed with a court should render the entire document including seals and signatures, with the translator’s certification stating name and contact details, because the opposing party may challenge the accuracy of the translation during the hearing.
