This Checklist sets out key considerations as to whether the appointment of an intermediary is ‘necessary’ in family proceedings, assessments to be undertaken, procedural requirements and case management, together with issues such as the scope of support to be provided, ground rules hearings and funding. The Family Procedure Rules 2010 (FPR 2010), SI 2010/2955, Pt 3A, together with FPR 2010, PD 3AA, make provision as to the participation of vulnerable persons in family proceedings and the giving of evidence by vulnerable persons. The rules include provision for the court to make ‘participation directions’ as to the involvement of a vulnerable person, protected party or child in family proceedings, as well as the power to appoint an intermediary. See Practice Note: Vulnerable persons—participation and evidence in family proceedings.
