‘16. … The CSA is designed to determine the amount of maintenance that should be paid for a child; ie a sum to cover living costs such as clothing, share of housing costs, pocket money and normal non fee paying school expenses etc. The PWC is generally the parent entitled to determine how the maintenance is to be spent on the child’s behalf. If parents decide that a child should be privately educated that is a cost over and above normal maintenance costs. How those fees are paid is a matter for agreement between the parents or failing agreement either parent could seek a court order for payment of the school fees.’
