Cal. Fam. Code § 3192

In a proceeding in which counseling is ordered pursuant to this chapter, where there has been a history of abuse by either parent against the child or by one parent against the other parent and a protective order, as defined in Section 6218, is in effect, the court may order the parties to participate in counseling separately and at separate times. Each party shall bear the cost of the party’s own counseling separately, unless good cause is shown for a different apportionment. The costs associated with a minor child participating in counseling shall be apportioned in accordance with Section 4062.
