First, lawyers can meet suspects, but non-lawyers can't. In the investigation stage of criminal cases, only lawyers can meet the parties. If you don't hire a lawyer, your family members can't meet with the parties during the investigation stage, which is not conducive to understanding the case.
Second, it is more conducive to fully understanding the facts of the case. Lawyers can understand the facts of the case, formulate defense strategies in advance, and fully communicate with criminal suspects on the facts so as to carry out defense work as soon as possible. Compared with not asking for a lawyer, asking for a lawyer is more conducive to the criminal suspect and his family to know the truth of the case.
Article 33 of the Criminal Procedure Law of People's Republic of China (PRC): In addition to exercising the right of defense, a criminal suspect or defendant may entrust one or two persons as defenders. The following persons may be entrusted as defenders:
(1) lawyers;
(2) A person recommended by a people's organization or the unit to which the criminal suspect or defendant belongs;
(3) Guardians, relatives and friends of criminal suspects and defendants.
A person who has been sentenced to punishment according to law or deprived of or restricted personal freedom shall not act as a defender. A person who has been dismissed from public office or has his lawyer's or notary's practice certificate revoked may not act as a defender, except the guardian or near relative of the criminal suspect or defendant.
