Every case depends upon evidence and credibility. It is well known that domestic violence can cause Post-Traumatic Stress Disorder (PTSD) and depression. Evaluators who are not well-trained in domestic violence may misdiagnose PTSD. Frequently, untrained forensic evaluators may misdiagnose domestic violence as borderline personality disorder (BPD) or paranoia. As well, during a marriage people may go for marriage counselling and may not realize the extent to which battering exists, especially if it is psychological, emotional battering. They may blame themselves. At some point they may recognize the battering but it may not have been raised during counselling. When the couple finally comes to court the abuser may raise the victim's mental health as an issue.
