The Virginia Judicial System website has Family Abuse Protective Order forms through ICAN. You can find the form for Petition for Protective Order - Stalking/Serious Bodily Injury.
The courthouse in your area will also have the forms you need, and the clerk may be able to help you there.
Someone in a domestic violence organization in your area may be able to help you get the forms and also help you through the process. To find help in your area, go to VA Advocates and Shelters.
