The VSS informs Victims about their rights relating to participation and reparations, and enables them to file complaints and Civil Party applications to the ECCC if they wish to do so (for details see Practice Direction on Victim Participation).This entails the provision of assistance in obtaining legal advice or a lawyer, supporting legal representatives and facilitating the grouping and collective representation of Victims. The VSS supports the work of the Co-Prosecutors and the Co-Investigating Judges by processing complaints and Civil Party applications and preparing reports for these offices. It also maintains contact with Victims and their lawyers regarding the status of their complaints and applications, and keeps them updated regarding developments in individual cases. The VSS ensures that the role of the section and the rights of Victims are explained in outreach events throughout Cambodia.

Lastly, the VSS ensures the safety and well-being of Victims who participate in the proceedings. This involves ensuring that Victims properly understand the risks sometimes inherent in such participation, as well as providing them with protective measures and other assistance, like psychosocial support.
