You can find Domestic Violence Protection order forms and Stalking Order Protection forms online.
You will also find standard civil protection order forms (for domestic violence and stalking) through the Domestic Violence Resource Center of the Ohio State Legal Services Association.
For other counties, you might have to get county-specific forms from the courthouse in that county. Go to Courthouse Locations to find the courthouse in your area.
A local domestic violence organization may be able to provide you with the necessary forms. Go to OH Advocates and Shelters to find an organization in your area.
