Hartwell and Thomas (Child support)

The case of *Hartwell and Thomas* concerned an application for a departure determination under the *Child Support (Registration and Collection) Act 1988* (Cth). The applicant sought to have the assessed child support payable by the respondent varied, arguing that the respondent’s actual income and financial resources were significantly different from those used in the initial assessment. The matter came before the court for review of a decision made by the Registrar.

The primary legal issue before the court was whether the respondent possessed a higher earning capacity than that reflected in the child support assessment. This required the court to consider the respondent's income, financial resources, and any other relevant circumstances, including the nature of his employment and any potential for increased earnings. The court had to determine if these factors warranted a departure from the standard assessment.

In reaching its decision, the court examined the evidence presented regarding the respondent's business income and his overall financial position. The court applied the principles governing departure determinations, focusing on whether the respondent’s earning capacity was intentionally underutilised or if there were other circumstances that justified an adjustment to the assessed child support. The court considered the respondent's ability to earn income and the extent to which his current financial situation reflected his true capacity. The court ultimately set aside the Registrar's decision and substituted its own determination.
