Despite the general principles of parental autonomy and privacy, domestic violence and child maltreatment invite police, lawyers, social workers, and judges into the most intimate spaces within a family. Domestic violence is described in terms of intimate partner violence, child maltreatment, and elder maltreatment. Because these topics would be sufficient for an entire separate book, this chapter focuses on the following specific issues related to these forms of domestic violence: domestic violence courts, corporal punishment, obesity as neglect, termination of parental rights, informal caregiving for elders, and mandatory reporting laws for elder maltreatment.
