These Rules amend the Family Proceedings Courts (Children Act 1989) Rules 1991 (“the 1991 Rules”) to provide that functions previously performed by an officer of the Children and Family Court Advisory and Support Service (“CAFCASS”) are to be performed, in relation to children ordinarily resident in Wales, by a Welsh family proceedings officer. The amendment follows the transfer of functions from CAFCASS to the National Assembly for Wales by section 35 of the Children Act 2004 for children ordinarily resident in Wales.
