Children need protection from their abusive parents. In the realm of custody litigation which involves abuse, the abusive parent tends to be the father while the protective parent is usually the mother, because most perpetrators of domestic violence and of child sexual abuse are male. We don’t know that much about what happens to protective fathers, since their cases are much less common, but we know that protective mothers frequently encounter a system that is insensitive, ignorant about the dynamics of abuse, and biased against women. In this context, mothers sometimes find themselves being forbidden by the court from protecting their children from a violent, cruel, or sexually abusive father. And this outcome is a tragic one, for children and for their mothers.
