Can a foreigner authorize a lawyer to deal with the police on their behalf? When being invited to work with the police, investigated, or involved in a criminal case in Vietnam, many foreigners worry: “Do I have to appear in person? Can my lawyer represent me entirely?” This article explains the applicable Vietnamese laws and how you can properly protect your legal rights.
Receiving a police invitation letter or summons can be stressful. Many foreigners fear arrest, language barriers, signing incorrect documents, or losing their legal rights. In criminal proceedings in Vietnam, every statement may significantly impact the investigation process. So, what does Vietnamese law say?

Under the Criminal Procedure Code of Vietnam 2015 (amended 2021), persons accused, suspects, witnesses, victims, and persons under denunciation all have specific rights and obligations during criminal proceedings.
Pursuant to Articles 60, 61, and 83:
However, an important point must be clarified:
A lawyer cannot completely replace the client during formal interrogation or statement-taking sessions.
In official procedures such as:
The investigating authority requires the person directly involved to be present. A lawyer may attend, advise, and protect rights, but cannot answer or sign statements on behalf of the client.
This means:
A foreigner cannot fully “delegate” attendance at formal interrogation sessions to a lawyer.
But that is not the full picture.
Although a lawyer cannot replace your testimony, a criminal defense lawyer in Vietnam plays a critical protective role:
For foreigners, language barriers and differences in legal systems pose serious risks. A misunderstood question or inaccurate answer may lead to significant legal consequences.
Therefore, even if a lawyer cannot entirely replace you, they serve as an essential legal safeguard throughout the process.
Not all situations require direct personal attendance. In certain circumstances, a lawyer may legally represent a foreign client under a power of attorney.
During pre-prosecution stages or when:
A lawyer may act under valid authorization.
Examples:
In such cases, a lawyer may:
However, if investigators require direct testimony, the individual must appear pursuant to a lawful summons.
If a foreigner is arrested, held in custody, or temporarily detained:
In practice, many foreign clients sign written statements without a lawyer present or without proper interpretation. This creates serious legal risk.
Important note: Having a lawyer does not guarantee exemption from criminal liability. Case outcomes depend on evidence, specific conduct, and assessment by competent authorities. However, legal representation helps ensure that proceedings are fair and lawful.

Most clients seek legal support after signing statements, being charged, or even detained.
But in criminal cases, the earliest stage is the most critical.
For foreigners involved in criminal cases in Vietnam, unfamiliarity with the legal system may create extreme psychological pressure.
One early mistake can significantly change the entire direction of the case.
