Generally, you should file a Response to Petition to Modify Child Support Order (FL Modify 502) and a Financial Declaration (FL All Family 011). 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. Please see Resources below for other agencies which provide additional information, referral services, or pro bono legal services.
