Is there law for family violence? example: republic act

It is important to understand that generally, family violence, which is usually referred to as domestic violence, is a matter of state law, not federal law. I cannot speak for all 50 states authoritatively, but I would imagine that all of them have statutes concerning domestic violence.  In Pennsylvania, for example, there is a Protection from Abuse statute.

You should also be aware that while most people seem to focus on spousal abuse, abuse of one's child or parent is often covered under such statutes.

In Pennsyvania, under the Protection from Abuse Act, consequences for abuse of a family member might include removal from the home or removal of a child from the home. When a child is abused, a government agency will usually become involved in the situation, and a child might be taken permanantly from the home. A violation of a Protection from Abuse Order can also lead to incarceration.

When one abuses a family member, the normal criminal charges also apply, so one might be found guilty of assault and battery, rape, attempted murder, and so on.

Domestic violence is a serious problem. It affects people of all ages, races, ethnic groups and socio-economic status. If someone you know is being abused, a good person to speak to about this is a school counselor.
