Morton and Lambert (Child support)

The case of Morton and Lambert (Child Support) concerned a dispute between the parties regarding the percentage of care for their child. The applicant, Morton, sought to revoke an existing determination of the percentage of care and have a new determination made. The respondent, Lambert, opposed this application. The matter came before the court for review of a decision made by the Child Support Registrar.

The primary legal issue before the court was whether the existing determination of the percentage of care should be revoked and a new determination made, or if the existing determination should be affirmed. This required the court to consider the evidence presented by both parties concerning the actual care arrangements for the child and whether those arrangements met the criteria for a change in the registered percentage of care.

The court affirmed the existing determination of the percentage of care. In reaching this decision, the court applied the principles of the *Child Support (Registration and Collection) Act 1988* (Cth) and relevant case law concerning the assessment of care arrangements. The court found that the evidence did not support a change to the registered percentage of care, and therefore the existing determination remained appropriate.
