Houchan and Houchan (Child support)

The Administrative Appeals Tribunal (AAT) considered the dispute between the parties, referred to as Houchan and Houchan, concerning the percentage of care arrangements for their child. The core of the disagreement revolved around whether there had been a material change in the established pattern of care that would warrant a revocation of existing percentage of care determinations and the making of new ones.

The Tribunal was tasked with determining whether the evidence presented established a sufficient change in the pattern of care to justify altering the previously determined percentages. This involved assessing the factual circumstances of the child's living arrangements and considering the legal criteria for revoking and remaking percentage of care determinations under the relevant legislation.

The Tribunal affirmed the decision under review, finding that the evidence did not support a conclusion that there had been a change to the pattern of care sufficient to warrant the revocation of the existing percentage of care determinations. The Tribunal applied the principles governing the assessment of care arrangements, focusing on the factual reality of the child's living situation and the legislative requirements for making such determinations.
