Immediate Steps After an Arrest
Your first 48 hours, what to say, and what not to sign. Ask for a lawyer and a translator. You can wait to sign until everything is explained. Section 13 of the Criminal Procedure Code requires an interpreter when you do not understand Thai. Criminal Law in Thailand is complex.
Common Criminal Charges for Foreigners
Thai law does not use the American split between misdemeanors and felonies. The Penal Code sets a single scale of penalties, from a fine up to the death penalty, and separates out a category of petty offences (ลหุโทษ) in Book 3 of the Code. Petty offences are the least serious, punishable by imprisonment of not more than one month, a fine of not more than 10,000 baht, or both. Everything else is a general criminal offence graded by the penalty the section carries, up to imprisonment, a heavy fine, or in the gravest cases the death penalty. Most offenses are defined in the Criminal Code of Thailand. However, there are other specific laws that support Criminal Law in Thailand.
We provide detailed information focusing on charges that may arise. Detailed insights on frequent criminal charges, part of criminal law in Thailand:
Drug and Alcohol Offenses
What counts as possession, sale, or trafficking, and why penalties are much harsher than many countries.
Personal Conduct and Speech
Crimes against Persons
Prostitution in Thailand is technically illegal. This is due to the Prostitution Prevention and Suppression Act of 1996. Soliciting in public is an offence under that Act. Penal Code sections 282 and 283 are a different thing: they punish procuring, seducing or taking away another person for an indecent purpose, with heavier penalties where that person is under eighteen and heavier still under fifteen, and section 283 where deceit, threats, violence or coercion are used.
Property and Financial Crimes
Property and financial crimes in Thailand cover a wide range of situations that often involve foreigners. Cases include fraud in property transactions, forged title deeds, embezzlement, and breaches of trust. Expatriates also face risks linked to investment scams, online fraud, or dishonest business partners.
Thai courts treat these offenses seriously, with penalties that may include imprisonment, fines, or both. Because property law and financial regulations in Thailand differ from many other countries, it is important to work with Thai lawyers who speak English and who are familiar with protecting foreign clients from such crimes, whether as victims seeking redress or defendants needing a strong defense.
Business and Employment-Related Offenses
Business and employment offenses in Thailand usually involve violations of company law, labor regulations, or anti-corruption rules. Common issues include:
• Directors not fulfilling their responsibilities.
• Misusing company assets.
• Committing accounting fraud.
• Ignoring rules from the Department of Business Development.
On the employment side, disputes often relate to wrongful termination, unfair labor practices, unpaid wages, or breaches of work permit conditions for foreign staff.
Both employers and employees risk penalties if they do not respect the Labor Protection Act and immigration rules. Thai authorities take these matters seriously, and companies found guilty of corporate or employment offenses face heavy fines, criminal charges for directors, and possible loss of business licenses.
Stay compliant and avoid criminal liability in your business activities:

- Nominee Companies and Foreign Business Act Violations
- Corporate Criminal Liability: Risks for Directors
- Tax Evasion and Money Laundering Implications
- White-Collar Crimes: Embezzlement, Fraud, and Corruption
- Cybercrime Laws: Online Fraud, Hacking, and Data Protection
Navigating the Thai Court System
Unlike in western countries, there is no jury system in Thailand. The legal process is usually faster. It is rare to see a lawyer object to evidence. I have seen many trials, and I have never seen an objection. It seems that hearsay and all types of evidence are usually accepted.
Cross-examinations are brief, and trials are conducted swiftly. Do not expect criminal law in Thailand to be similar than western countries.
Prepare yourself with essential knowledge about court proceedings:
- Criminal Procedure Code in Thailand: This covers the steps of a Thai criminal case. It includes arrest, appeal, timelines, and important articles to know.
- Police Interview: How Thai police collect statements, the role of translators, and how to protect your rights during questioning.
- Criminal Trial Procedures: What to Expect in Thai Courts
- Criminal Appeals: Supreme Court Processes
- Evidence Laws: What Can Be Used Against You
- Common Criminal Defenses: Self-Defense, Necessity, Duress
- Military Courts in Thailand : When military jurisdiction applies, how it differs from civilian courts, and what that means for your defense.
Immigration and Border Control Issues
Borders and immigration issues often intersect with criminal law in Thailand. Overstaying a visa, working without a valid permit, or entering the country illegally can lead to arrest, fines, detention, and deportation. In more serious cases, such as smuggling, human trafficking, or using false travel documents, penalties include long prison terms.
Foreigners facing immigration-related criminal charges need representation from Thai lawyers who understand both criminal procedure and immigration law to protect their rights and limit long-term consequences.
Key immigration-related criminal topics:
- Thailand Visa Overstay: Criminal Charges and Solutions
- Criminal Deportation from Thailand: Process and Appeals
- Illegal Entry, Harboring, and Human Trafficking
Post-Conviction Processes
Once the trial concludes, and if the defendant is found guilty, the court will proceed with sentencing. The defendant has the option to appeal the decision within a standard 30-day period. The appeal process does not include hearings. It is done only by submitting documents. The judges then make the final decision. Appeals can be lengthy, spanning several years, and during this period, a defendant may request bail. Furthermore, there is a possibility of a second appeal at the Supreme Court.

Key Differences for Foreigners
- No juries: criminal cases are judge-led.
- 48 hours: police can hold you up to 48 hours before court. Further detention requires court orders, issued in blocks, with maximums based on the charge.
- Bail: possible, but not automatic for foreigners. Risk of flight and local guarantees matter.
- Interpreter: you have a right to an interpreter under CPC s.13.
- Consular contact: Thailand follows the Vienna Convention on Consular Relations. You can ask the police to notify your embassy under Article 36.
Recommendations for Foreign Visitors
Familiarize yourself with basic Thai laws, especially concerning drugs, alcohol consumption, and prohibited activities.
Thai law requires you to show identification when asked. Carry a clear copy of your passport bio page and entry stamp. Police may still ask for the original, and you could be detained until it is produced.
You can backstop this practical advice with official travel guidance.
Be respectful of Thai culture and traditions.
Avoid arguments and confrontations with locals.
If arrested, remain calm, politely request a lawyer, and do not sign any documents you don’t understand. Foreigners should always ask for a translator and contact their embassy. Thai law allows you to request an interpreter and have your embassy informed if you are arrested. Always make sure you understand any document completely. You have the right to wait to sign. A qualified interpreter or lawyer can explain it to you. This is allowed by section 13 of the Criminal Procedure Code.
Thailand acceded to the Vienna Convention on Consular Relations on April 15, 1999. Article 36 requires the option to have the embassy/consulate notified and to communicate with consular officers.
Knowing the basics of criminal law in Thailand can help foreign visitors stay safe and avoid legal issues. Remember, it’s always best to consult with a qualified lawyer if you have any questions or concerns.

If you need a lawyer now
Criminal matters are time-sensitive: bail is decided early, and what is said in the first police interview is hard to undo. Bail applications and criminal defence are quoted individually: the range between a first-instance traffic matter and a serious charge is too wide for a fixed fee to be honest. A consultation is 2,000 THB per hour and you get a written estimate before any work begins. To speak to someone, book a consultation.
Frequently Asked Questions
What should I do if I am arrested in Thailand?
Stay calm, avoid signing documents you do not understand, and ask for a lawyer and your embassy. Try not to give statements until your lawyer is present.
Do I have the right to a lawyer in Thailand?
Yes. Suspects have the right to legal counsel and, for serious offences, to an interpreter, and you may request a lawyer before answering questions.
How does bail work in Thailand?
Bail can be requested at the police, prosecution or court stage and is usually secured by cash, property or a surety, with the amount set according to the seriousness of the charge.
What are the penalties for drug offences in Thailand?
Penalties range from fines and rehabilitation to long prison terms depending on the type and quantity of drug, with trafficking carrying the most severe sentences.
Can a foreigner be deported after a criminal case in Thailand?

Take the Legal Health CheckLast reviewed: 6 September 2026 against the Penal Code and the Criminal Procedure Code in the statute library, and against the United Nations treaty register. This is a hub page, so its checkable legal claims are few and each was read at source. One correction was made. Penal Code sections 282 and 283 punish procuring, seducing or taking away another person for an indecent purpose, with heavier penalties where that person is under eighteen and heavier again under fifteen, and section 283 where deceit, threats, violence or coercion are used. Neither section mentions soliciting, which is an offence under the Prostitution Prevention and Suppression Act instead, so the two were separated. Three further claims were checked and found correct, and are recorded here so nobody re-derives them: Criminal Procedure Code section 13 does require an interpreter to be provided without delay where a party cannot speak or understand Thai; a petty offence under Penal Code section 102 is punishable by imprisonment of not more than one month, a fine of not more than ten thousand baht, or both, which is the figure after the general uplift of Penal Code fines and not the older one; and Thailand acceded to the Vienna Convention on Consular Relations on 15 April 1999, confirmed against the United Nations treaty register rather than a secondary source. This review did not cover the many pages this hub links to, whose own law is reviewed on those pages; the structured data on this page, which is the subject of a separate open question about which FAQ pattern the site should standardise on; or the descriptions of offences for which this page cites no provision.
Sexual offences carry their own rules on consent, age and penalties, and are covered separately in our guide to sex crimes in Thailand.
