Most of your local court houses can help you out. Normally the court will require you to go down and fill out some simple paperwork explaining who the person is and what actions they have committed that are offensive to you. It is always helpful to put together a timeline of what has been happening and to list specific dates of each incident. Most judges want to see a pattern of behavior before they issue a restraining order. After you fill out the paperwork, you may appear in front of judge who may ask you questions about your petition. If the judge grants your petition you will need to have the bully served with a copy of the restraining order, and you should also give a copy to the management company. Most states will allow the person who is served with the order to request a hearing on the order. If that happens, you will have to appear in court for the hearing and again explain why the order should remain in place. You may want to contact your local legal aid society and see if they can help you out.
Go to the Room C-125 of the Snohomish County Courthouse, and they can help you there. They will help you on how to properly complete the forms there. The type of order that you should request is an "Anti-Harrassment Order". The courthouse is 3000 Rockefeller Ave, Everett.
