A restraining order or order of protection is a form of legal injunction that requires a party to do, or to refrain from doing, certain acts. A party that refuses to comply with an order faces criminal or civil penalties and may have to pay damages or accept sanctions. Breaches of restraining orders can be considered serious criminal offences that merit arrest and possible prison sentences. The term is most commonly used in reference to domestic violence, harassment, stalking or sexual assault. In the United States, each state has some form of domestic violence restraining order law, and many states also have specific restraining order laws for stalking and sexual assault. Restraining and personal protection order laws vary from one jurisdiction to another but all establish who can file for an order, what protection or relief a person can get from such an order, and how the order will be enforced.
