In accordance with the Family Procedure Rules 2010 (FPR 2010), SI 2010/2955, 25.6 the court’s permission is required for expert evidence to be adduced in family proceedings. In addition, a party may not instruct an expert in proceedings relating to children, and a child may not be medically or psychiatrically examined or otherwise assessed for the purposes of the provision of expert evidence in the proceedings, without first obtaining permission from the court (sections 13(2)–13(5) of the Children and Families Act 2014 (CFA 2014)). Specific provision in relation to public children proceedings is set out at FPR 2010, SI 2010/2955, 25.6(a), which provides that an application for permission should be made ‘as soon as possible’ and ‘in Part 4 proceedings referred to in rule 12.2 and in so far as practicable other public law proceedings referred to in that rule, no later than a Case Management Hearing’.
