California Code, Family Code - FAM § 6305

(1) Both parties personally appear and each party presents written evidence of abuse or domestic violence in an application for relief using a mandatory Judicial Council restraining order application form.  For purposes of this paragraph, written evidence of abuse or domestic violence in a responsive pleading does not satisfy the party's obligation to present written evidence of abuse or domestic violence.  By July 1, 2016, the Judicial Council shall modify forms as necessary to provide notice of this information.

(2) The court makes detailed findings of fact indicating that both parties acted as a primary aggressor and that neither party acted primarily in self-defense.
