Usually the suspect's family. Only after the family members of the criminal suspect detained in criminal detention entrust a lawyer to represent the case will the lawyer meet the criminal suspect after handling the agency procedures. 1, the lawyer's meeting here refers to the lawyer's right to meet in the process of criminal proceedings. The lawyer's right to meet is an extremely important right of lawyers in criminal proceedings. When a lawyer meets a client in the process of civil litigation or other non-litigation legal affairs, it is generally not called "lawyer meeting" but "meeting the client". 2. The purpose of establishing the lawyer interview system according to law is to ensure that criminal suspects and defendants can realize their litigation rights in the process of criminal proceedings. Criminal suspects and defendants are in a passive position in the process of criminal proceedings, especially those who have been taken criminal compulsory measures. They are in a state of detention and restriction of personal freedom. They are bound to be restricted in exercising their litigation rights, and of course there are certain limitations. Therefore, it is a favorable way for lawyers to meet them, understand their wishes, provide them with legal help, and file complaints and accusations on their behalf when their rights are violated. 3. The lawyer's right to meet comes from two aspects, one is the authorization based on the entrustment relationship, and the other is the right based on the lawyer's position in criminal proceedings. The former is based on the authorization of the client's rights, and its purpose is to make up for the lack of self-defense ability of criminal suspects and defendants, provide them with legal advice, apply for bail on their behalf, and appeal and accuse on their behalf. The latter is a right endowed by law based on the status and role of lawyers in criminal proceedings. It is an important job for lawyers to perform their duties as defenders, understand the alleged crimes and related cases by meeting with criminal suspects and defendants, and put forward "innocent" and "lighter" defense opinions for criminal suspects and defendants.
