In criminal cases, what can victims and their families do when they hire lawyers?

The main reasons for the victims and their families to hire lawyers are as follows: 1. After the victim was infringed, the investigation organ failed to deal with it, and the victim and his family members were worried about being wronged, so they asked a lawyer to represent them. In this case, the lawyer's job is mainly to collect evidence of major criminal clues or improper performance of duties by the investigation organ, appeal, accuse or reflect the situation to the relevant authorities, urge the investigation organ to handle the case quickly, and redress grievances for the victims; 2. Hire a lawyer at the trial stage. The lawyer's agency work is mainly to help the victim collect evidence of accusation and criminal incidental civil compensation, represent the victim in court to demand compensation and accuse the defendant, and refute the views of the prosecutor and defender. After the judgment of the first instance, if the victim and his family are dissatisfied with the civil compensation, the lawyer will file an appeal on his behalf; If he refuses to accept the criminal judgment, he will lodge a protest with the procuratorate on his behalf.
