If there are incident(s) of family abuse, the court can order a person to have no contact, or limited contact, with the victim or victim's children, or to leave the home and stay away for a certain period of time. This is called a Protective Order (sometimes known as a Restraining Order). If a person does not follow the rules and violates the protective order, that person can be arrested.
The law clearly states that Family Abuse is an act involving violence, force, or threat, including any forceful detention which results in physical injury or places one in reasonable fear of death, sexual assault or bodily injury, and is committed by a person against a family or household member.
