Mugford and Howson (Child support)

This matter concerned an appeal by the father, Mr Mugford, against a departure determination made by the Registrar of the Child Support Agency. The dispute centred on the Registrar's decision to depart from the formula assessment of child support payable by the father to the mother, Ms Howson, to include contributions towards the costs of private school fees and childcare expenses for the parties' two children. The father sought to have this departure determination set aside. The appeal was heard by the Federal Magistrates Court of Australia.

The primary legal issue before the Court was whether the Registrar had erred in making the departure determination. Specifically, the Court was required to consider whether the Registrar had correctly applied the principles and criteria set out in section 117 of the *Child Support (Registration and Collection) Act 1988* (Cth) when assessing whether to depart from the formula assessment. This involved examining whether the private school fees and childcare costs constituted necessary expenses for the children, and whether the income and financial resources of both parents were adequately considered in the Registrar's decision.

The Court found that the Registrar had erred in her assessment. While acknowledging that private school fees and childcare costs could, in certain circumstances, be grounds for a departure determination, the Court held that the Registrar had failed to properly consider the capacity of the father to meet these additional costs, given his income and financial circumstances. The Court emphasised that a departure determination should only be made where it is just and equitable to do so, and that the formula assessment is presumed to be the appropriate method for calculating child support. The Registrar had not adequately demonstrated why departing from the formula was necessary in this instance, particularly in relation to the father's financial position.

The Court ordered that the Registrar's departure determination be varied, effectively setting aside the additional child support payments for private school fees and childcare. The child support assessment was to revert to the formula amount.
