Donaldson and Child Support Registrar (Child support)

The case of *Donaldson and Child Support Registrar* concerned a dispute regarding the percentage of care arrangements for a child. The applicant, Donaldson, sought to challenge decisions made by the Child Support Registrar concerning these arrangements. The matter came before the court for review of the Registrar's determinations.

The central legal issues before the court were whether there had been a change to the likely pattern of care for the child, and consequently, whether the existing percentage of care determinations should be revoked and new ones made. The court also considered whether the Registrar had taken reasonable action in light of non-compliance with court orders and the application of an interim period.

In its reasoning, the court examined the evidence presented regarding the actual and likely future care arrangements for the child. It applied the principles of the *Child Support (Registration and Collection) Act 1988* concerning the determination of care percentages and the circumstances under which existing determinations can be revoked or substituted. The court found that the Registrar's decision was not supported by the evidence and that the Registrar had failed to properly consider the relevant factors. The court determined that the decision under review should be set aside and substituted with a new determination reflecting the correct assessment of the care arrangements.
