Professional interpreter services in Thailand
In short
Interpreting renders speech from one language into another in real time; translation is the written equivalent. In Thailand five settings come up most often: court and legal hearings, police investigations, district offices for marriage and family registration, business meetings and conferences, and remote or online sessions. Choose the mode (consecutive or simultaneous), confirm the exact language pair, and check the requirements of the agency handling your matter — some require the interpreter to identify themselves and sign the record.
Where a person giving evidence cannot speak or understand Thai, an interpreter must be provided under section 13 of the Criminal Procedure Code, and the interpreter takes an oath or affirmation before acting.
A registrar may require an interpreter where one party does not understand Thai, so that the party confirms understanding before signing. Practice varies by district office — confirm with the office where you will file.
NAATI issues Certified Interpreter and Certified Provisional Interpreter credentials separately from translator credentials. Being a certified translator does not automatically make a person a certified interpreter.
Consecutive interpreting is used for interviews, court and negotiations. Simultaneous interpreting is used for conferences and requires booths and headsets; standard practice pairs two interpreters per language combination.
Court, police investigator, district office, immigration or a private engagement — each has different rules. Some require the interpreter to present ID and sign the record of the session.
2. Confirm the language pair and variety
State the source and target languages precisely, including variety or dialect (for example Mandarin or Cantonese, Modern Standard Arabic or a regional variety), so the right interpreter is assigned the first time.
3. Choose the mode and equipment
Interviews and hearings use consecutive interpreting. Large conferences use simultaneous interpreting with booths and headsets. For online sessions, test the platform's interpretation channel and keep a backup line.
4. Send documents and terminology in advance
Share agendas, case files, names of people and companies, and technical terms. Accuracy on the day depends mostly on the preparation material received beforehand.
5. Confirm date, time, venue and contact person
Fix the appointment time, meeting point, on-site contact, and a fallback plan if the agency reschedules, so a court or registry slot is not lost.

Common misunderstandings
• Booking an interpreter after the court or registry date is fixed, forcing the whole appointment to be postponed.
• Assuming a certified translator is also a certified interpreter — NAATI treats these as separate credentials.
• Not sending documents or terminology in advance, which leads to inaccurate rendering of technical terms.
• Using a relative or an opposing party as interpreter, which agencies may reject on impartiality grounds.
• Planning a simultaneous conference without booths and audio equipment, so interpreters cannot work to standard.
• Failing to check in advance whether the agency allows the interpreter to attend online.
Frequently asked questions
What is the difference between interpreting and translation?
Interpreting is spoken and happens live; translation is written and produces a document. A NAATI-certified translation is a written product with a certification statement, while an interpreting booking covers a person attending a session in person or online.
Does a court in Thailand provide the interpreter, or do I arrange one?
Section 13 of the Criminal Procedure Code requires that an interpreter be provided where a person cannot speak or understand Thai. In practice parties often arrange an interpreter themselves and confirm acceptance with the court. Check the practice of the court hearing your case before the appointment.
Can a relative interpret for me at a police station or district office?
Agencies commonly decline interpreters with an interest in the matter, because it affects the reliability of the record. Using an independent interpreter avoids that objection.
Do I need a NAATI-credentialled interpreter in Thailand?
Thai agencies do not require NAATI credentials. NAATI matters when an Australian agency needs to verify the person's qualification. Confirm the requirement with the agency that will receive your matter.
Is remote interpreting accepted by Thai government offices?
It depends on the office. Where the interpreter must sign the record on the spot, attendance in person is usually required. Confirm with the specific office before scheduling.
How far in advance should I book?
Book as early as your appointment date is known, particularly for less common language pairs and for simultaneous conferences that need equipment and a pair of interpreters.
How much does an interpreter cost?
Fees vary with language pair, mode, venue and duration, so we quote per booking. Contact our staff by phone, LINE or email with the date, place and language pair.
Which languages can you cover?
We arrange interpreters for a wide range of language pairs with Thai and English. Send us the exact pair and variety and we will confirm availability for your date.

Booking an interpreter: steps and what to prepare
Interpreting can be consecutive, simultaneous, or over phone and video. Matching the mode to the setting keeps the meeting accurate and shorter.
Step 1: Describe the setting
State whether it is a government, court, medical, business or online engagement, with the date, time and estimated hours.
Step 2: Choose the right mode
Two-party meetings usually use consecutive interpreting; large conferences use simultaneous with equipment; urgent matters use phone or video.
Step 3: Send briefing material in advance
Agendas, terminology, names and titles let the interpreter prepare and reduce misunderstandings.
Step 4: Confirm the booking details
Confirm the meeting point, the coordinator and a fallback plan if timing shifts.
What to prepare
Date, time, venue and estimated hours
Language pair and register of the engagement
Agenda or briefing material in advance
Participant list and organisation-specific terminology
Why sets get sent back
Late bookings in peak periods limit access to subject-matched interpreters
Skipping the briefing in technical settings forces terminology stops mid-meeting
Court and some government settings prescribe interpreter credentials — check before confirming
If you would rather not track each step yourself, send scans on LINE. Our team, which has handled this type of work for over 15 years, will map your document route first — where it should end, how many copies you need, and which steps would be wasted — and you decide afterwards whether to do it yourself or hand it to us.
Choosing the wrong mode leads to appointments running short or equipment gaps. This table compares four options and their limits.

What it certifies
Issued or signed by
When to use
Limits
Consecutive interpreting
The interpreter renders speech in turns, alternating with the speaker
Professional or NAATI-certified interpreter
Government interviews, medical appointments, small meetings, business negotiations
Roughly doubles the total time; allow extra room in the appointment
Simultaneous interpreting
The interpreter renders speech in real time through equipment or a separate audio channel
Professional interpreters, usually working in pairs
Conferences, seminars and events with a large audience
Requires equipment, and long sessions normally need two interpreters rotating
Remote interpreting (phone or video)
The interpreter joins by telephone or an online meeting platform
Professional interpreter
Short or urgent appointments, or participants in different countries
Quality depends on connection and audio; some authorities require on-site attendance
Document translation
Written translation with a certification statement
Certified translator, e.g. NAATI-certified
Documents must be lodged as files or printed copies
A different service from interpreting; an interpreter's attendance does not replace a certified translation
Start from the receiving authority and work backwards to the steps you actually need
For Australian authorities lodging online, a NAATI-certified translation is usually the end of the chain
If the destination asks for “original with seal”, check whether MFA or embassy steps are also required
Do not run ahead to the next step before the destination confirms — some steps must be redone from scratch
If you are unsure where your document chain should stop, send scans and the name of the receiving authority on LINE. Our advisory team, with more than 15 years on this type of work, will map the route first so you do not pay for steps you never needed.
On-site and remote interpreting suit different jobs. We ask about the setting, the number of speakers and any requirement set by the authority before recommending a mode.
What we check before starting
Whether the authority specifies a mode or a credential level
Participant count, duration, and whether two interpreters need to rotate
Connection quality and equipment, if the session is remote
Where we tell you not to spend
For short sessions with few speakers, remote interpreting is usually enough and avoids travel cost
Sending reference material in advance genuinely shortens time in the room
What we do not promise
• The receiving authority decides the outcome; we do not promise results
• Government fees and processing times vary with the period and the workload of each office
• We do not give legal, financial or medical advice beyond the scope of translation and certification
