Generally, you should file a Response to Petition to Decide Parentage (FL Parentage 302). These forms are available at the Washington Courts’ website. You must file a copy with the Jefferson County Superior Court and serve a copy on all parties, including the Jefferson County Prosecuting Attorney’s Office. Usually the Response must be filed and served within 20 days of you being served or accepting service.
It is recommended that you contact an attorney for legal assistance. If you are unable to find an attorney for your case, online resources may be available to assist you in filling out the forms. Please see Washington Law Help for their packet on responding to a Petition to Decide Paternity.
