According to the law, risk agency is prohibited in criminal cases, and only fees can be charged first. Criminal cases are generally divided into three stages: investigation stage, examination and prosecution stage and first instance stage. The suspect's family can negotiate with the law firm to pay all the agency fees in one lump sum, or pay the agency fees in installments. Regarding this charging standard, different regions have different standards, and the charging of criminal cases is generally carried out in stages. But in short, it is not possible to represent risks, and it is a serious illegal act for lawyers to represent criminal cases to achieve risk agency.
