Parenting orders and the best interests of the child 

When parents separate, disputes about children are resolved under a framework built around a single organising idea: what outcome best serves this particular child. This article explains that paramount consideration, the kinds of parenting orders a court can make, and why the analysis resists a fixed formula.

The paramount consideration

In any parenting proceeding, the best interests of the child are the paramount consideration. This does not mean a factor among several to be balanced against parental convenience, fairness between the parents, or either parent's wishes — it means the child's best interests are the outcome the court is ultimately trying to achieve, and other considerations are only relevant to the extent they bear on that question.

This is deliberately different from an approach that starts from parental rights or entitlements. A parent does not have a right to a particular outcome; a child has an interest in an arrangement that serves their welfare, safety and development, and the court's task is to identify what that arrangement is on the facts before it.

No fixed formula or presumption

A student's most important task in this area is to resist reasoning from a fixed rule. There is no formula that produces a set division of time, and no presumption that a particular arrangement — equal time, primary residence with one parent, or any other pattern — applies as a starting point, confirmed in AMS v AIF (1999) 199 CLR 160.¹ What outcome serves a child's best interests is assessed on that child's own circumstances: their age, developmental needs, relationship with each parent and significant others, and any relevant risk factors. The same facts pattern can produce different outcomes for different children, and a court is not constrained to choose between only the arrangements the parties have proposed.

Relevant considerations commonly include the benefit of a meaningful relationship with both parents where safe, the need to protect the child from harm including exposure to family violence or abuse, the child's own views (weighed according to their age and maturity), the practical effect of any proposed arrangement on the child's stability, and the capacity of each parent to meet the child's needs. None of these operates as a mechanical override of the others; they are weighed together in light of the individual child.

Kinds of parenting orders

A parenting order can deal with any aspect of a child's care, welfare and development. The recurring categories are:

• who a child lives with — the practical living or residence arrangement, which may be with one parent primarily, shared between both, or in some other configuration;
• who a child spends time with — including time with a parent the child does not primarily live with, and often with other significant people such as grandparents; and
• parental responsibility and decision-making — how major long-term decisions about a child's health, education, religious upbringing and name are to be made, including whether parents must consult and agree or whether one parent may decide.

Parental responsibility in this sense is about decision-making authority, and is conceptually distinct from the practical living arrangement — a parent can hold decision-making responsibility for major long-term issues without the child living with them for most of the time, and vice versa.

Safety as a threshold consideration

Where there are genuine concerns about violence, abuse or neglect, a court will not proceed on the assumption that a relationship with both parents is inherently beneficial; safety considerations can and do displace what would otherwise be a preferred arrangement. This connects closely to the framework covered in this module's article on family violence protections, which explains how such concerns are raised and proven in parenting proceedings.

One constitutional point has moved, and an answer written from AMS alone now starts in the wrong place. In APLA Limited v Legal Services Commissioner (NSW) [2005] HCA 44² Hayne J said at [420] that "the principles stated in AMS v AIF should now be accepted as the applicable doctrine", so the AMS formulation was not left open by that case having found it unnecessary to decide the challenge before it. But Palmer v Western Australia [2021] HCA 5³ has since confined the intercourse limb to discriminatory burdens: Kiefel CJ and Keane J at [50], and Gageler J at [113]–[114] explaining why APLA does not stand in the way. So for a relocation order the first question is whether the burden on interstate movement is discriminatory at all; only then does the AMS justification question arise.

Applying this in a problem question

1. State the paramount consideration and explain that it is the organising outcome, not one factor among equals.
2. Reject any answer that assumes a fixed starting-point arrangement or formula.
3. Work through the child's individual circumstances — age, relationships, views, stability and any safety concerns.
4. Identify which category of parenting order is really in dispute: living arrangements, time, or decision-making responsibility, since these are conceptually separate.
5. Explain how any family violence or safety concern would be weighed, rather than assumed away.
