Guzman and Hernandez (Child support)

The Administrative Appeals Tribunal (AAT) considered an application by Mr. Guzman (the applicant) to revoke existing percentage of care determinations made under the *Child Support (Registration and Collection) Act 1988* (Cth) concerning his children with Ms. Hernandez (the respondent). The applicant contended that there had been a change to the likely pattern of care for the children, which would justify a revocation of the existing determinations.

The primary legal issue before the Tribunal was whether the applicant had demonstrated a change in the likely pattern of care for the children that would warrant the revocation of the existing percentage of care determinations. This required the Tribunal to assess the evidence presented by both parties regarding the actual and anticipated care arrangements for the children.

The Tribunal affirmed the decision under review, finding that the applicant had not established a change to the likely pattern of care. The Tribunal applied the principles governing the revocation of percentage of care determinations, which require a significant and ongoing change to the care arrangements. Based on the evidence, the Tribunal concluded that the existing percentage of care determinations accurately reflected the likely future care arrangements for the children and therefore refused to revoke them.
