What is the 90AE Family Law Act?

Definition and legal context: equal shared parental responsibility family law act explained

The phrase “equal shared parental responsibility family law act” in this article refers to the statutory presumption that the Family Law Act creates for decision-making about major long-term issues for children. The Act states that, when making parenting orders, the court must apply a presumption of equal shared parental responsibility unless there are reasons not to, such as family violence or risks to the child, and the full legislative text is available for reference on the Family Law Act site Family Law Act 1975.

The presumption sits alongside a broader decision-making framework that prioritises the child’s best interests, and the court guidance explains how decision-making responsibility is legally distinct from arrangements for where a child lives and how much time each parent has with the child Federal Circuit and Family Court of Australia parenting guidance.

Section 61DA of the Act sets out the presumption of equal shared parental responsibility. The text of that provision and related provisions is often read together with the court’s best-interests criteria, which are listed in section 60CC of the Act and guide how the presumption is applied in specific cases AustLII section 61DA.

In short, the term “shared parental responsibility” refers to decision-making duties for major long-term issues, not an automatic entitlement to equal time. Courts treat those topics separately when they draft parenting orders, and decisions about time and living arrangements follow a different analysis based on what will serve the child’s best interests Federal Circuit and Family Court of Australia parenting guidance.

In practice, the presumption of equal shared parental responsibility applies specifically to decision-making about major long-term issues. Typical examples of those issues are the child’s education, major medical treatment and religious upbringing, and courts commonly treat such matters as decisions that require consultation or shared responsibility rather than daily scheduling AustLII section 61DA.

How equal shared parental responsibility family law act operates in practice

When parents disagree about a major long-term decision, the presumption means the court starts from the position that both parents should share the responsibility for making those types of decisions unless there is evidence or statutory reason to depart from that position. The court then evaluates the practicalities of implementing shared decision-making in the child’s life and may set out processes for resolution of future disputes in the parenting orders.

Certain circumstances displace the presumption. If there is family violence or risk to the child’s safety, the Act and court guidance allow the court to conclude that equal shared parental responsibility is not appropriate, and those exceptions frequently lead to different decision-making arrangements or single parental responsibility for particular issues Federal Circuit and Family Court of Australia parenting guidance.

Courts applying the presumption do not treat it as an automatic outcome that eliminates judicial scrutiny. The judge will assess the evidence, the practicality of joint decision-making, and whether the child’s best interests will be served by the proposed arrangement. The court continues to apply the best-interests criteria under section 60CC when structuring orders.

Because the presumption focuses on decision-making, it does not automatically govern daily care arrangements. Time and living arrangements remain matters the court resolves separately, using the best-interests framework and considering the child’s need for a meaningful relationship with each parent alongside protections from harm Federal Circuit and Family Court of Australia parenting guidance.

What section 90AE does and how property orders can bind third parties

Section 90AE is located in the property division portion of the Family Law Act and permits a court to make an order under section 79 that is binding on a third party in certain circumstances, so that property relief can have effect against parties who are not directly before the court AustLII section 90AE.

That power sits separately from the parenting provisions of the Act and is part of the court’s toolbox when addressing complex property settlements where assets or legal interests involve third parties, such as trusts, company interests or security interests held by non-parties. Further discussion of debt substitution and creditors is available in specialist commentary Moores on dealing with debt substitution.

In practice, orders that bind third parties raise questions about enforcement and the impact on third-party rights, and courts approach such orders with attention to statutory limits and the particular facts of each case. Legal advice is usually necessary to understand how a s90AE order would operate against specific third-party interests (see detailed analysis at Mondaq).

From negotiation to court: dispute resolution, certificates and pre-action steps

Most parenting applications require an attempt at family dispute resolution and a s60I certificate before filing for parenting orders, unless a statutory exception applies for family violence or urgent safety concerns, and the Attorney-General’s Department provides guidance on these pre-action requirements Attorney-General’s Department guidance.

A typical sequence recommended in official guides and Legal Aid materials is: try negotiation and create a parenting plan if possible; attend family dispute resolution with an accredited practitioner; obtain a s60I certificate if the dispute is unresolved; and then, if necessary, apply to the Federal Circuit and Family Court for parenting orders. Each step helps clarify positions and can reduce the need for contested court proceedings. For assistance, see the contact page.

There are exceptions to the s60I certificate rule. Where family violence, child safety issues or urgent circumstances are present, the Act and departmental guidance allow an applicant to proceed without a certificate. The guidance notes the importance of specialist advice in those circumstances so that safety is prioritised and appropriate evidence is presented to the court.

Court guides and Legal Aid services also outline practical considerations such as preparing documents that show parenting history, communication records, and any professional reports that relate to the child’s welfare; these materials help the court evaluate risk and practical arrangements if an application proceeds Federal Circuit and Family Court of Australia parenting guidance.

How courts decide: key factors and decision criteria under the Act

Two matters stand out in many cases: the advantage to the child of having a meaningful relationship with each parent, and the necessity of protecting the child from harm. The court balances these considerations, using evidence about the child’s circumstances, parental capacity, and any risk indicators to decide how orders should be structured.

The presumption of equal shared parental responsibility is one part of the statutory scheme. It does not override the best-interests assessment; rather, it informs the starting point for decision-making responsibility and is weighed against evidence about risk, the practicality of shared decision-making, and the child’s needs.

Judicial outcomes are fact-specific. Courts exercise discretion when the evidence points toward tailored arrangements for decision-making, time and living conditions, and judges may impose communication processes or require parent education or family reports to support the child’s welfare in ongoing disputes Federal Circuit and Family Court of Australia parenting guidance.

Common mistakes and practical pitfalls parents should avoid

A frequent mistake is assuming that the presumption of equal shared parental responsibility automatically means equal time. The court guidance clarifies that shared parental responsibility concerns decision-making about major long-term issues and does not on its own translate into symmetric time or living arrangements Federal Circuit and Family Court of Australia parenting guidance.

Skipping family dispute resolution when it is required, or misunderstanding the limits of the exceptions, can cause procedural setbacks. Where an applicant proceeds to court without the required s60I certificate and no applicable exception, the court may take procedural steps that delay progress, so it is important to confirm whether a certificate is needed Attorney-General’s Department guidance.

Another pitfall is underestimating how section 90AE issues can complicate property matters. When third-party interests are present, binding orders can raise enforcement and priority questions that require specialist legal advice to resolve sensibly and to ensure a party’s intended relief is practically achievable AustLII section 90AE and practical commentary such as Armstrong Legal on third parties.

Practical steps and example scenarios for families

Commonly recommended practical steps start with negotiation and a parenting plan. If parents cannot agree, the usual pathway is family dispute resolution, obtaining a s60I certificate if necessary, and then applying to the Federal Circuit and Family Court for parenting orders where agreement is not reached, which is the sequence set out in official guidance and public resources Federal Circuit and Family Court of Australia parenting guidance. See recent updates on the site’s news page.

Scenario A, a high-conflict case without proven family violence: parents may be encouraged to use structured dispute resolution, to involve family consultants or independent children’s lawyers where appropriate, and to seek orders that include clear processes for decision-making and for resolving future disagreements. The court will test the practicality of shared decision-making and may require communication protocols or other supports.

Scenario B, where safety concerns exist or allegations of family violence are made: a parent or the court can proceed without a s60I certificate if urgency or risk justifies immediate orders. In those cases the court places protection and safety at the forefront of decision-making and may limit shared responsibility or allocate primary decision-making for specific issues to protect the child.

These scenarios are examples to illustrate how steps and choices might differ depending on the facts. They are not legal advice. Readers should consult primary legislation, rely on court guidance, and seek tailored legal advice when facts are complex or when property and third-party interests intersect with parenting issues Attorney-General’s Department guidance.
