70% of contested custody disputes involve domestic violence.

Statistics

Multiple studies confirm the grim reality that at least 70% of contested custody disputes involve domestic violence.  Further, there is considerable overlap between domestic violence, child abuseand incest.  Multiple studies show that the majority of men who abuse their wives or girlfriends also abuse the children.  At least half of incest perpetrators also committed domestic violence, and daughters of batterers are 6.5 times more likely than other girls to be victims of incest.
