If you are arrested in Thailand, ask straight away for your embassy to be told and for a lawyer, and do not answer questions until you understand them. Thai law gives you the right to notify someone, to stay silent and to have a lawyer present, but bail is rarely granted, there is no formal legal aid system, and your embassy cannot get you released.
This page walks through what usually happens after an arrest, from the police station to the first court hearing, remand and deportation. It is based on the Thai Criminal Procedure Code (in an unofficial English translation) and on the UK Foreign, Commonwealth & Development Office (FCDO) information pack for detained British nationals, last updated in August 2023. It is not legal advice. Every case depends on the charge and the facts, and only a lawyer licensed in Thailand can advise you on yours.

Your rights at the police station
The Criminal Procedure Code sets out what police must do at the moment of arrest (section 83). The officer has to tell you that you are under arrest, state the accusation, show a warrant if there is one, and tell you that you may make a statement or remain silent, that what you say can be used as evidence, and that you may consult a lawyer.
Section 7/1 then lists the rights of anyone held in custody. Officials must explain them at the first opportunity:
- to notify a relative or another person you choose about the arrest and where you are held (section 84 adds that this must be done without delay and free of charge);
- to meet and consult a lawyer in private;
- to have a lawyer or a person you trust present while you are questioned;
- to receive reasonable visits from relatives;
- to get prompt medical treatment if you are ill.
The FCDO describes the same rights in plain terms and adds one that matters most in the first hours: you may decide whether or not to answer police questions. Under section 84, a confession made to the arresting officer during the arrest itself cannot be used as evidence, but a statement given later in questioning can be. Phone calls beyond the notification are at the investigating officer's discretion.
Thai police statements are written in Thai, so ask for a translation before you sign. If you cannot read a document, you cannot know what you are agreeing to. Ask for the interpreter, ask for your lawyer, and tell your embassy if no translation was offered. Being calm and polite helps; arguing with officers does not.
Interpreters: free at the police station, limited in court
Thai law requires the investigation to be conducted in Thai. According to the FCDO, if you need English the investigating officer "should provide an interpreter", free of charge. In some places a third party, such as staff from a tourist assistance center, does the translating. If nobody translates for you, say so to your embassy when it makes contact.
In court, the court provides a free interpreter, but in most cases only when a court official speaks to you directly. The FCDO warns that unless you have an English-speaking lawyer, you may have to pay for an interpreter yourself if you want to follow the whole hearing. Documents in a foreign language must also be translated into Thai before the court will use them.
How your embassy is told, and what it can do
The Thai authorities should ask whether you want your embassy contacted. The FCDO says this notification "normally takes place within 24 hours but sometimes takes several days". If a friend or relative knows you have been arrested, they can contact your embassy directly. British families can call the FCDO in London on +44 (0)20 7008 5000, 24 hours a day.
Embassies of most countries offer a similar, limited service. The FCDO lists what British consular staff can and cannot do, and it is a fair guide to what to expect from any embassy:
What consular staff can do
- Visit you, in person or by video call
- Give you a list of local English-speaking lawyers and interpreters
- Pass messages to family and help them send you money
- Tell police or prison doctors about your medical needs, with your permission
- Explain how the local legal system works
- Raise mistreatment with the authorities if you agree
What they cannot do
- Get you out of jail or interfere in the Thai justice system
- Give legal advice or investigate the case
- Pay for a lawyer, an interpreter or your bail
- Transfer bail money for you
- Stop a deportation
Readers who registered their trip with their embassy before traveling may be easier to trace in an emergency; our page on registering with your embassy lists which countries still offer that.
From police cell to the first court hearing
Section 87 of the Criminal Procedure Code says a person who is not released must be brought before a court within 48 hours of being taken to the inquiry official's office, unless there is force majeure. That is the legal limit, not a promise. The FCDO's description of practice is different: "You will usually be taken to court about 3 days after arrest", and depending on the offense and whether bail is available, "you can expect to spend up to 12 days detained in police cells".
Police cells are basic. The FCDO says your belongings, including your phone, are usually stored in a locker, food and water are provided but no bedding, and cells can be overcrowded. If you take regular medicine, tell the officers and your embassy at once.
At the first hearing, a judge decides whether you are released on bail or remanded in custody.
Bail is the exception, not the rule
"Bail is rarely granted in Thailand," says the FCDO. It is at the judge's discretion and depends on the offense, your circumstances and any police objection. For minor offenses, bail is usually paid at the police station soon after the arrest; otherwise it is paid to the court.
If bail is granted, the court usually keeps your passport, though you can normally travel inside Thailand. Conditions such as reporting to the police must be followed exactly. Missing a hearing or trying to leave the country usually leads to a new arrest warrant and the loss of the bail money. The FCDO says the embassy can contact friends or family who may be willing to help with bail, but it cannot move the money for you.
Remand, charges and how long a case can take
Without bail, you are moved to a prison on remand and brought back to court every 12 days for the remand to be renewed. The Criminal Procedure Code limits pre-trial detention to 48 or 84 days in total, depending on the seriousness of the offense. Remand prisoners are often held in the same prisons as convicted prisoners.
Once you are formally charged, the court and both sides agree trial dates. Thai trials have no jury and are not held on consecutive days: evidence is heard half a day or a day at a time, with gaps of weeks or months. According to the FCDO, serious cases can take a year or more, and trial dates up to two years away "are not unheard of". Time spent in detention is deducted from any sentence. The FCDO notes that some offenses, such as those involving Class 1 narcotics, can bring life imprisonment or even the death sentence.
Ask for the written list of English-speaking lawyers on the first consular visit. Embassies keep these lists, and the FCDO advises agreeing all fees in advance. Some lawyers ask for a cash payment up front; all should give you an estimate of their costs.
Lawyers and the limits of legal aid
Many websites say Thailand gives free legal aid to anyone arrested. The FCDO says the opposite: "there is no formal legal aid process in Thailand and only a small number of lawyers provide pro bono services." If you cannot pay for a lawyer, the court may appoint one, but usually only when the charge carries a sentence of more than 10 years. You must accept the lawyer the court appoints, and roster lawyers often speak little or no English.
In practice, that means most foreigners hire a private lawyer, paid by themselves or their family. Check whether your travel or expat insurance includes any legal-expenses cover; our guide to travel insurance for Thailand explains what policies usually include, and you should read your own policy's wording.
Deportation after a sentence, or without one
The FCDO says it is common practice for foreigners convicted of an offense to be deported once the sentence is served, after a period in an Immigration Detention Centre. There is no formal process to contest it, and a British citizen who entered on a British passport is deported to the UK. The UK also has a prisoner transfer agreement with Thailand that can let a sentence be finished at home; the conditions are strict and the process can take up to a year. Other countries' arrangements differ, so ask your own embassy.
New deportation regulations in force since 28 August 2026 also allow foreigners to be deported without a criminal conviction if the authorities find their conduct contrary to public order or public morals, according to the FCDO. Deportees can face restrictions on returning. Overstaying is the most common reason visitors end up in immigration detention; our page on overstaying in Thailand covers fines, bans and that process. Whether a past conviction or prison term affects a later visit is explained in our guide to entering Thailand with a criminal record.
Where foreign visitors most often get into legal trouble
Most visitors never deal with the police except to report a theft. Arrests of tourists tend to follow a short list of situations, each covered on its own page:
- Drugs. The FCDO warns that even small quantities can bring heavy fines or prison. Cannabis is a special case with its own rules: see what the cannabis law says now.
- Vapes and e-cigarettes, which are banned: see the vaping ban.
- Prescription medicines that Thailand treats as narcotics, such as some ADHD drugs and codeine: check the Thai FDA permit before you fly.
- Drones flown without registration or approval: see the drone rules.
- Business and property arrangements. The US Embassy warned in September 2026 that foreigners have been arrested over nominee structures for land and companies.
Police may also ask to see your passport. The FCDO says a copy of the photo page is usually enough, but you may have to show the original at a police station within 24 hours; our page on carrying your passport has the details.
If someone you know has been arrested
Contact the person's embassy first, either the consular section in Bangkok or the foreign ministry's emergency line at home. Give the full name, date of birth, passport number if you have it, and where and when the arrest happened. Ask the embassy for its lawyer list, and before sending money to anyone who says they are acting for the detained person, check with the embassy who they are.
The Tourist Police (1155) are a national unit set up to help foreign visitors, but they are not a substitute for a lawyer. Our page on emergency numbers in Thailand explains when to call 191 and when to call 1155. For the broader picture of crime and risk, see whether Thailand is safe to visit.
Frequently asked questions
How long can police hold you in Thailand before you see a judge?
The Criminal Procedure Code says a detained person must be brought before a court within 48 hours of reaching the inquiry official's office. The FCDO says that in practice the first hearing is usually about three days after arrest, and some people spend up to 12 days in police cells.
Will my embassy get me out of jail in Thailand?
No. Embassies cannot interfere in the Thai justice system, pay for a lawyer or pay your bail. They can visit you, give you a list of English-speaking lawyers and interpreters, contact your family and raise concerns about your treatment.
Can I get bail in Thailand as a foreigner?
It is possible but uncommon. The FCDO says bail is rarely granted and depends on the offense, your circumstances and the judge's decision. If it is granted, the court usually keeps your passport until the case ends, so you cannot leave Thailand.
Is there free legal aid for foreigners arrested in Thailand?
Not in a formal sense. The FCDO says there is no formal legal aid process and only a few lawyers work pro bono. A court may appoint a lawyer, usually only when the charge carries more than 10 years, and that lawyer may not speak English.
Do I have to answer police questions in Thailand?
Under the Criminal Procedure Code you must be told that you may make a statement or remain silent, and that what you say may be used as evidence. You also have the right to have a lawyer or a trusted person present during questioning.
