If you are arrested or held by police in Vietnam, the most useful things you can do are to stay calm, say clearly that you want your embassy informed, ask for an interpreter and a lawyer, and refuse to sign any record you cannot read or do not agree with. Vietnamese criminal procedure gives a suspect the right to be told why they are held, to present their own account, to have defence counsel and to use their own language through an interpreter. It also states that a suspect is not obliged to give evidence against themselves or admit guilt.
The first hours matter because that is when statements are taken and papers are signed, often in Vietnamese and under stress. This guide walks through what usually happens, what you are entitled to ask for, how to handle questioning, and how family or colleagues outside can help. It describes principles of the Criminal Procedure Code, which has been adjusted alongside the 2025 reorganisation of the police and the courts, so check the exact time limits and steps that apply to your situation with a licensed Vietnamese lawyer.
How an arrest usually unfolds in Vietnam
Vietnamese law distinguishes several ways a person can be taken in. Someone may be caught in the act and handed to the police, detained in an emergency because there are grounds to believe they are about to commit a serious crime or flee, or arrested under a decision that has been approved by the procuracy. In each case the person is brought to an investigation body, usually the police, which records the event in a written report and decides whether to place the person in custody while the facts are checked.
Custody is short by design. The Criminal Procedure Code sets an initial period of a few days, typically three, which can be extended only with the approval of the procuracy, the prosecuting authority that supervises investigations. By the end of custody the investigators must either release the person, start formal proceedings and charge them, or apply a different preventive measure such as temporary detention, which also needs the procuracy to sign off. In practice foreigners are sometimes questioned for many hours at a police station first, without any formal custody decision, and are then allowed to leave.
Since March 2025 the police no longer have a district level; cases are handled by commune and ward police for minor matters and by provincial police investigation units for criminal investigations. For you this mainly means that the officers who first stop you may not be the ones who conduct the investigation, and that you may be moved from a local station to a provincial facility. Keep asking, politely, which body is holding you and on what basis, because that is the information your embassy and lawyer will need.
Your core rights from the moment you are held
To know why you are held. You are entitled to be told the reason for the arrest or custody and to receive the relevant decision. Ask to see it and ask for it to be explained to you in a language you understand. If no decision exists yet, that itself is useful to know.
To an interpreter. Criminal proceedings are conducted in Vietnamese, but anyone who does not speak it has the right to use their own language, and the authority conducting the case is responsible for arranging an interpreter. Do not rely on a bystander, a friend of the complainant or an officer with some English for anything that will be written down.
Not to incriminate yourself. The Code states that a person accused of a crime is not obliged to give evidence against themselves or to admit guilt. You can say that you will give your account once a lawyer and an interpreter are present. Say it calmly and do not argue the facts on the spot.
To a defence lawyer. You can have defence counsel from the time you are held in custody or arrested. A lawyer has to register with the investigating body before they can act, and only lawyers licensed in Vietnam can do this; a lawyer from your home country can advise your family but cannot represent you in the Vietnamese proceedings.
To have your family and your embassy informed. Investigators are required to notify the family of a person held, and for a foreign national the consular post of their country is informed through the diplomatic channel. Ask for this explicitly and repeat the request in writing if you can. Some countries have consular agreements with Vietnam that make notification mandatory.
To read and correct records before signing. Every statement is written into a record that you are asked to sign. You have the right to read it, or have it read to you through the interpreter, and to ask for corrections or add your own notes. If you disagree, you can refuse to sign or write that you disagree.
Handling the first round of questioning
The first interview is where most avoidable damage happens. People who are frightened tend to talk too much, guess at details they do not remember, or agree to a version of events just to make the questioning end. Vietnamese investigators commonly take several statements over time and compare them, so a careless first account can be used to cast doubt on everything you say later.
A safe approach is to give only your identity details at first, explain that you want an interpreter and a lawyer, and say that you will cooperate fully once they are present. Being cooperative in tone matters in Vietnam; a calm, respectful manner is far more effective than citing rights in a loud voice or threatening to call the newspapers. Do not lie, do not invent alibis and never try to destroy or hide evidence, including messages on your phone, because that turns a difficult situation into a much worse one.
You may be asked to hand over your phone, passport and other belongings. Ask for a written list of what is taken, check that it is accurate before you sign it, and keep a copy if one is offered. If you are asked to unlock a phone or give passwords, say that you want to discuss it with your lawyer first; the legal position on compelled access is not something to negotiate alone in a police interview room.
Under the Code, interrogations of suspects at detention facilities and investigation offices are to be audio or video recorded. Recording protects you as well as the investigators, so you can ask whether the session is being recorded and ask your lawyer to check later that the recording matches the written record.
What family, friends or your employer can do from outside
People outside are often more effective than the person held, because they can make calls, collect papers and pay for help. A short, organised list of tasks keeps them from losing the first days.
- Call the embassy or consulate of your country and give your full name, passport number, date of birth, where and when you were taken, and which police body is believed to be holding you.
- Find a Vietnamese criminal defence lawyer and ask them to register as defence counsel as soon as possible. The embassy can usually provide a list of local lawyers, and it is reasonable to ask a lawyer on AI Co Van (aicovan.com) for a first orientation while you search.
- Gather documents that show your status and ties to Vietnam: a copy of your passport and visa or residence card, your employment contract or business registration, a tenancy agreement and evidence of family in the country. These help if the question of release or an alternative to detention comes up.
- Write down a timeline of events as soon as possible, including names of witnesses, while memories are fresh. Share it only with the lawyer.
- Arrange money for essentials and fees through legitimate channels and keep every receipt. Detainees may be allowed to receive certain items and funds for daily needs according to facility rules.
- Avoid posting about the case on social media or contacting the complainant or witnesses directly. Even well-meant messages can be read as pressure and can harm the person held.
If the person held is a company employee or director, the employer should also check whether the matter could involve the company itself, and keep internal communications factual and limited until a lawyer has looked at the situation.
What happens next: possible outcomes after custody
Custody is a decision point, not an end point. The table sets out the outcomes that commonly follow and what each means for you in practical terms.
| Outcome | What it means | What to focus on |
|---|---|---|
| Release without charges | Investigators find no basis to continue, or the matter is minor and handled administratively. | Get your passport and belongings back; ask whether any exit restriction remains. |
| Release with a non-custodial measure | Proceedings continue, but you are released under conditions such as a residence restriction, a guarantee, a cash deposit or a suspension of exit. | Follow conditions strictly; ask your lawyer to keep track of summons and deadlines. |
| Temporary detention | You are charged and held in a detention facility while the investigation continues, with the procuracy's approval. | Lawyer access, consular visits, health needs, and whether a change of measure can be requested. |
| Administrative handling | The conduct is treated as an administrative violation and punished with a fine or other administrative sanction rather than prosecution. | Read the decision, check your right to complain, and pay or contest within the stated period. |
| Expulsion as a sanction | In some administrative or criminal outcomes, a foreigner may be expelled from Vietnam. | Consular help, personal affairs, and any period during which re-entry is barred. |
Each of these steps has its own rules and its own avenue for complaint. The procuracy supervises the legality of custody and detention, and complaints about procedural decisions can be addressed to it; your lawyer will know which body to write to and how quickly.
When you need a Vietnamese lawyer
Any time you are held by police on suspicion of a crime, you need a Vietnamese criminal defence lawyer, not a general business adviser and not a lawyer from your home country acting alone. Only a lawyer licensed in Vietnam can register as defence counsel, attend interrogations, review the case file at the appropriate stage, file complaints about procedural decisions and represent you before a court. The earlier they register, the more of the record they can influence.
Look for someone who handles criminal cases regularly, not occasionally, and who is willing to explain each step to you or your family in a language you understand, directly or through a trusted interpreter. Agree in writing on the scope of their work, on how they will report to you and to your family, and on how fees are structured. Be cautious with anyone who promises a specific outcome or suggests that money paid to officials can make the problem disappear; that is not legal help, and it can create a new offence.
A lawyer is also worth consulting when the matter seems minor, for example an alleged scuffle in a bar or an accusation from a business partner, because what begins as a misunderstanding can become a formal denunciation. Early advice often prevents a statement that later proves costly. If you cannot afford a lawyer and the charge is serious, ask about state-appointed defence and legal aid, which the Code provides in specified situations.
Frequently asked questions
Do I have to answer police questions if I am arrested in Vietnam?
You should give your identity details, but the Criminal Procedure Code states that an accused person is not obliged to give evidence against themselves or to admit guilt. It is sensible to say calmly that you will give your account once an interpreter and a lawyer are present.
Will the police tell my embassy that I have been arrested?
For foreign nationals the consular post of their country is normally informed through the diplomatic channel, and many bilateral agreements make this mandatory. Ask explicitly and early, and have family call the embassy as well so that nothing depends on a single notification.
Can a lawyer from my home country represent me in Vietnam?
No. Only lawyers licensed to practise in Vietnam can register as defence counsel in Vietnamese criminal proceedings. A lawyer from your home country can still help by advising your family, coordinating with the embassy and working alongside a Vietnamese lawyer.
How long can police hold me without charging me?
Custody has a short initial period under the Code, usually a few days, and extensions require the procuracy to approve them. By the end of custody you must be released, charged or placed under another measure. Ask a licensed lawyer to confirm the limits in your case.
Should I sign the statement the police have written?
Only after it has been read to you in a language you understand and it accurately reflects what you said. You may ask for corrections, add your own note, or refuse to sign and record that you disagree with the content.
Can I offer money to resolve the matter quickly?
No. Offering money to police or other officials to drop a case is bribery and is itself a crime in Vietnam. Pay only fines, deposits and fees that are formally decided, through official channels, against proper receipts.
