Key takeaways
- You may choose whether to give a statement. Arrest-stage confessions and investigation-stage statements have different evidential rules.
- Language assistance depends on communication needs, not nationality alone.
- The right to consult a lawyer is distinct from the conditions requiring the state to provide one.
- You can request provisional release during custody. You do not have to wait 48 hours, and cash security is not required in every case.

Do you have to answer police questions after an arrest?
Under Section 83 of Thailand’s Criminal Procedure Code, an arresting official must explain the allegation, show an arrest warrant if there is one, and inform the arrested person of the right to give a statement or remain silent. The official must also explain that statements may be used as evidence and inform the person of the right to meet and consult a lawyer or prospective lawyer.
Before questioning a suspect in the investigation, Section 134/4 requires notice of the right to give a statement or not, and the right to have a lawyer or trusted person attend the questioning. If the suspect declines to give a statement, that must be recorded. These are procedural rights; choosing to exercise them does not itself dispose of the allegation. See OCS Criminal Procedure Code, Sections 83 and 134/4.
Can a confession at the time of arrest be used in court?
Section 84 draws an important distinction. A confession made by an arrested person to the arresting official, or to the administrative or police officer at the arrest or handover stage specified in that section, must not be admitted as evidence. Other statements at that stage may be admitted to prove guilt only after the required rights have been explained.
Section 134/4 separately excludes statements made to the inquiry officer before the required rights notification or compliance with Sections 134/1–134/3 from use as evidence to prove that person’s guilt. The circumstances and stage of the statement therefore matter. Neither rule means that every other item of evidence disappears or that the prosecution automatically ends. See OCS, Sections 84 and 134/4.
What if you cannot understand Thai?
Section 13 requires language interpretation where necessary in the investigation, preliminary examination or trial. Where a victim, suspect, defendant or witness cannot speak or understand Thai, or can communicate only in a local language or dialect, and has no interpreter, the inquiry officer, prosecutor or court must arrange one without delay.
The interpreter must translate accurately without adding to or omitting the meaning, take the required oath or affirmation, and sign the translation. The section also provides for sign-language interpretation or other appropriate communication methods when needed. Payment for an interpreter arranged under the section follows the relevant agency regulations.
Being a foreign national is not the only test: the person’s ability to understand and communicate matters. Nor does Section 13 automatically promise a complete translation of every document in the file. If a question or written record is unclear, identify the problem and request an explanation or interpretation before signing. See OCS, Section 13.
When can you speak to a lawyer?
Section 7/1 gives an arrested person or suspect in custody or detention the right to meet and consult a prospective lawyer privately. It also covers having a lawyer or trusted person attend questioning during the investigation. Section 134/3 expressly recognises the suspect’s right to that attendance. See OCS, Sections 7/1 and 134/3.
Must the state provide a lawyer in every case?
The conditions under Section 134/1 must be distinguished from the general right to consult a lawyer. Before questioning begins, the inquiry officer must ask whether the suspect has a lawyer:
| Circumstance | State-provided lawyer before questioning |
|---|---|
| The offence carries the death penalty, or the suspect was aged 18 or younger when the charge was notified. | If the suspect has no lawyer, the state must arrange one. |
| The offence carries imprisonment. | If the suspect has no lawyer and wants one, the state must arrange one. |
Section 134/1 contains a qualified urgent exception after a lawyer has been arranged. Where the lawyer cannot meet the suspect and either gives no notice of the difficulty or gives notice but does not attend within a reasonable time, the inquiry officer may proceed in the urgent circumstances covered by the section and must record the reason in the investigation file. It is therefore misleading to promise that questioning can never proceed until a lawyer arrives. See OCS, Section 134/1.
Do you have to wait 48 hours before requesting bail?
No. A request for provisional release can be made during custody. Section 106 identifies the appropriate decision-maker according to the stage of the case. Before charges are filed in court, a person in police or prosecution custody applies to the inquiry officer or prosecutor, as appropriate. A person detained under a court warrant before filing applies to that court. Once the case is filed, the application goes to the trial court, with further rules governing the appeal stages.
Section 107 requires a prompt decision and states that suspects and defendants should be granted provisional release under the statutory criteria. An order granting release must be implemented immediately. This is not a guarantee that every application will succeed. See OCS, Sections 106 and 107.
The 48-hour rule in Section 87 concerns bringing an arrested person before a court where provisional release has not been granted and continued custody is necessary for investigation or prosecution. Time is measured from arrival at the inquiry officer’s office under Section 83, subject to statutory exceptions. Section 87 also prohibits custody beyond what the circumstances require. The rule is not a minimum detention period or a deadline for completing a trial. See OCS, Section 87.
Does bail always require a cash payment?
No. Thai law distinguishes prakan, the bail undertaking or bond, from lak prakan, the security supporting it. Under Section 110, offences carrying a maximum prison term exceeding ten years require a bail undertaking, but security may or may not be required. Other cases may involve release without an undertaking, with an undertaking, or with both an undertaking and security. The amount demanded must not be excessive, and applicable preventive conditions and measures must be considered. See OCS, Section 110.
What if provisional release is refused?
Section 108/1 requires reasonable grounds to believe that one of the listed risks exists: flight, interference with evidence, further danger, an unreliable bail applicant or security, or obstruction of or harm to the investigation or court proceedings. A refusal must give reasons, communicated promptly in writing to the suspect or defendant and the applicant.
Section 119 bis provides routes to appeal a court’s refusal. However, a Court of Appeal order upholding the first-instance court’s refusal is final under that provision. A fresh application for provisional release remains possible. Do not confuse appealing a refusal with submitting a new application addressing the reasons for it. See OCS, Sections 108/1 and 119 bis.
What should you do first?
- Ask what allegation is being made and identify the officer and location responsible for the case.
- Request private legal consultation and explain any language or communication difficulty.
- Before giving a detailed account or signing, ensure you understand the questions and the record; ask for inaccuracies to be addressed.
- Ask counsel to identify the correct route for provisional release and gather material addressing the actual concerns about release.
- Keep copies of available records and written decisions so that deadlines and next steps can be assessed.
These steps are practical preparation, not a promise of release or a particular outcome. The exact charge, stage, evidence and applicable procedure remain important.
Frequently asked questions
Can a foreign suspect remain silent in Thailand?
Yes. Sections 83 and 134/4 recognise the choice to give a statement or not, with rights notifications at the relevant stage. Exercise the right clearly and obtain advice about the particular case.
Does every foreign suspect automatically receive an interpreter?
Section 13 focuses on language and communication needs. Where its conditions are met and there is no interpreter, the inquiry officer, prosecutor or court must arrange one without delay. Nationality alone is not the test.
Will the state provide a lawyer if I cannot afford one?
Section 134/1 uses the offence and age conditions described above. In imprisonment cases, a suspect who has no lawyer and wants one must be provided one. The section’s stated test is not simply a financial means test.
Can I request bail before 48 hours have passed?
Yes. Section 106 permits an application during custody to the appropriate authority. The 48-hour rule does not require you to wait before seeking provisional release.
Does a refusal of bail end every chance of release?
No. Section 119 bis provides appeal routes for court refusals and preserves the ability to make a fresh application. A Court of Appeal refusal upholding the first-instance refusal is final under that section, so the procedural route matters.
