Criminal Defence Thailand: Summons, Rights & Bail

If summoned or detained, first confirm whether you are a witness, suspect or defendant and which authority handles the case. Rights, procedures and documents differ. Keep the papers and appointment details, ask about allegations and applicable rights, and explain any difficulty understanding Thai. Provisional release is case-specific: offering security does not guarantee approval. Engagement and counsel's attendance must be confirmed before the appointment.

Checks and preparation for each situation
Situation	What to check	Preparation
Received a summons	Check whether you are called as a witness or suspect, the authority and date	Keep the papers and envelope; use official contact channels. If unable to attend, seek instructions—do not assume a postponement
Arrested or detained	Location, responsible officer, alleged charge and available records	Ask about your rights and counsel. Tell officers about medical or language needs; do not resist or destroy evidence
Seeking provisional release	Police, prosecutor or court stage, previous order and conditions	Check case-specific grounds and supporting documents. Release may involve security or no security; payment does not guarantee release
You are an injured party	Chronology, evidence of loss and details of those involved	Distinguish a complaint, private prosecution, joining a prosecution and compensation; check each route's requirements and time limits

Information for assessment without compromising evidence

Identify your status, appointment, case reference if available and attendance location. Do not post case details publicly.
Keep originals, full files, dates and senders. Do not edit messages, delete material or coordinate witness accounts.
Explain your language, interpreter needs, health and travel constraints using only necessary information.
Confirm the document channel, conflicts and engagement scope before sensitive disclosures. Do not send passwords or OTPs.

How the matter proceeds

1.Urgent intake and charge assessment
The attorney reviews the warrant and alleged facts, identifies the possible charges and penalties, and explains suspect rights under the Criminal Procedure Code.
2.Attending the police interview with counsel
Explain a suspect's right to give or withhold a statement and access counsel under the law. Check that the record reflects what was said before signing; request an interpreter if needed and do not guess facts.
3.Assess a provisional-release application
Identify the authority for the current stage and prepare supporting grounds, evidence and any required conditions or security. After refusal, review the order and available reconsideration or renewed-application route. Approval cannot be guaranteed.
4.Prosecution stage and trial
Where grounds exist we petition the public prosecutor, then file the defence, present rebuttal evidence and follow the strategy agreed with the client.
5.Judgment, appeal and remedies
We explain the judgment and any conditions imposed, assess appeal grounds within the statutory period, and address compensation or restoration of rights.

Before you decide

Confirm your status and seek advice about rights before a statement. Read the record before signing and flag errors; do not ignore a summons or resist officers.
Payment or a private settlement does not end every criminal allegation. Check whether the offence is compoundable and the agreement's legal effect.
A suspect has the right to consult counsel privately and to an interpreter if Thai is not understood.
Appeal deadlines are short and strictly applied; a missed deadline is very hard to cure.

Frequently asked questions

What should I do if I receive a summons?

Keep the papers and envelope; check your status, authority and appointment using official contact details. Seek advice before the date. If unable to attend, contact the authority and confirm any permission to postpone. Messaging the office is not confirmation of postponement or counsel's attendance.

How much security is needed for bail?

There is no universal amount. Release may be with or without security under the law and the authority's assessment. Check the stage, allegation, risks and supporting evidence. Security is separate from attorney fees, and offering money does not guarantee release.

What if bail is refused?

Obtain the order and reasons, then identify the decision-maker and case stage. Renewed applications, reconsideration and appeals have different requirements. More money alone may not address the refusal; assess new facts, supporting evidence and the applicable deadline.

What extra preparation applies to foreign nationals?

Explain difficulty understanding Thai and confirm interpreter arrangements with the authority; language needs are not determined by nationality alone. Prepare your passport, contact address and case papers, and raise any need for consular contact. Check translation and certification per document rather than notarising everything automatically.

Can an injured party pursue the case?

Several routes exist, but legal standing, offence type, evidence and time limits must be checked. Complaints, private prosecution, joining the prosecutor and compensation claims each have conditions; not every person qualifies for every route. Conflicts must be checked before engagement.

Can a criminal case be settled?

Compoundable offences such as defamation and some fraud can be settled by law, while offences against the state cannot — the distinction must be clear before any agreement.

Can the lawyer really sit in on questioning?

Yes. The Criminal Procedure Code gives a suspect the right to have counsel or a trusted person present during questioning; the right should always be used.

How are criminal defence fees calculated?

Request a written quote identifying the case stage, hearing scope, applications and exclusions. Separate attorney fees, travel, interpretation, translation and any security. Do not assume appeals or additional attendance are included; no fee guarantees a result.
