Yes, victims must provide some evidence, but the evidence can be obtained from other parties. For instance, it can be a letter or a statement from a women's shelter for victims of violence, a statement from a doctor or a family practice, a police report, photographs, affidavits from family members, neighbours, co-workers, and so on. In cases like that, we can refer women to support organizations that can help them gather the information.
