About this work
What does the best interests test actually mean?
That the child's interests are the only thing the court is weighing. Section 16(1) says the court shall take into consideration only the best interests of the child, and that word does real work: what is fair between the parents is not a consideration at all.
Within the test there is a hierarchy. Section 16(2) requires primary consideration to be given to the child's physical, emotional and psychological safety, security and well-being. Every other factor is weighed underneath that, which is why safety concerns reshape a case in a way that no other issue does.
The eleven factors in section 16(3) then cover the ground. Several of them surprise parents. Paragraph (c) asks about each parent's willingness to support the child's relationship with the other, so a parent who obstructs contact is damaging their own position. Paragraph (e) requires the child's views and preferences to be considered, with weight according to age and maturity. Paragraph (f) names cultural, linguistic, religious and spiritual upbringing and heritage, which matters a great deal in families where the parents come from different traditions.
Section 16(5) is the one clients most need to hear. Past conduct is not considered unless it is relevant to the exercise of parenting time or decision-making. An affair, a bad divorce, or years of unpleasantness between the adults is not evidence about parenting unless it affected the children.
