You should also review the specific statutes regarding restraining orders. Search the website for the Revised Code of Washington for the statutes, or RCWs. That website is http://apps.leg.wa.gov/rcw/.
Be sure to comply with all court rules regarding page limits, deadlines, service on the court and other party, and format. You should certainly meet with a lawyer in the county the restraining order was filed.
