What is the standard of review for family support decisions?

We begin by noting that the standard of review for family support decisions is significant deference. This is informed by both the discretion involved in making support orders and the importance of finality in family law litigation. An appeal court should only intervene where there is a material error, a serious misapprehension of the evidence, or an error of law. An appeal court is not entitled to overturn a support order simply because it would have made a different decision or balanced the factors differently: Hickey v. Hickey, 1999 CanLII 691 (SCC), [1999] 2 S.C.R. 518, at para. 12.
