Gilligan and Hallam (Child support)

This matter concerned an appeal by Gilligan against a decision of the Child Support Registrar concerning the percentage of care for the parties' child. Gilligan sought to revoke existing percentage of care determinations made by the Registrar, arguing that there had been a change to the likely pattern of care. Hallam opposed the revocation.

The primary legal issue before the Court was whether the Registrar's refusal to revoke the existing percentage of care determinations was correct. This required the Court to consider whether there had been a change to the likely pattern of care for the child, and if so, whether that change warranted the revocation of the existing determinations.

The Court affirmed the Registrar's decision, finding that there was no material change to the likely pattern of care for the child. The Court applied the principles governing the assessment of percentage of care, which require a consideration of the actual and reasonably foreseeable future care arrangements. As no such change was established, the existing determinations were upheld.
