If the judge decides that there was abuse and that there is also a credible threat to the plaintiff's safety, a final order of protection will be granted and will last for up to one year.
After the hearing, a judge can issue a protective order that lasts up to 18 months, and can later be renewed after a hearing in front of a judge. The parts of the protective order that tell the abuser to not abuse, harass, or interfere with you can last forever.
The specific elements you need to prove to get a restraining order vary from state to state, but in general, you need to show: A specific instance or instances of abuse or harassment (such as sexual assault by an intimate partner) The threat of violence or of further abusive behavior or harassment.
