When a marriage or de facto relationship breaks down, the intersection between divorce and child custody becomes one of the most sensitive and complex areas of Australian family law.
Both processes fall under the jurisdiction of the Federal Circuit and Family Court of Australia (FCFCOA) and are primarily governed by the Family Law Act 1975 (Cth).
While divorce legally ends a marriage, child custody-referred to as parental responsibility-determines how decisions about a child’s care, welfare, and development will be made. This guide explains the legal framework, procedural requirements, and practical implications for families navigating divorce and custody disputes in Australia.
Under Australian law, divorce and child custody proceedings are legally distinct but often occur concurrently.
A divorce application is an administrative process, while custody (parenting) matters involve judicial consideration of a child’s best interests under Section 60CC of the Family Law Act 1975 (Cth).
To obtain a divorce, the applicant must demonstrate:
If there are children under 18, the Court will not grant the divorce order unless it is satisfied that proper arrangements have been made for their care, education, and support.
Parenting arrangements can be formalised in three main ways:
When children are involved, the law requires a focus on the best interests of the child above all else.
The FCFCOA considers both primary considerations-such as the child’s right to maintain a relationship with both parents and their right to safety-and additional factors like the child’s views, stability of each household, and any family-violence history.
Before applying to the Court for parenting orders, parents are generally required to attempt Family Dispute Resolution (FDR) and obtain a Section 60I certificate from an accredited practitioner. Only in cases involving family violence, abuse, or urgency may this requirement be waived.

Australian law distinguishes between legal responsibility (decision-making power) and physical custody (day-to-day care).
Common arrangements include:
Courts prefer arrangements that enable meaningful involvement by both parents, provided it does not compromise the child’s wellbeing.
A contested matter arises when parties disagree on issues such as living arrangements, time spent with each parent, or financial support.
These cases require judicial determination and often involve reports from family consultants or independent children’s lawyers (ICLs) appointed by the Court.
By contrast, uncontested cases-where parties agree-are typically finalised through Consent Orders, saving time and costs. Even in contested cases, the Court encourages dispute resolution and may adjourn proceedings to allow mediation under Part IIIA of the Family Law Act.
Costs depend on the complexity of the case, level of cooperation, and legal representation. Typical expenses include:
Those facing financial hardship may apply for fee exemptions or reductions, and Legal Aid Commissions in each state can provide limited assistance for eligible clients.
The timeframe varies according to whether the matter is contested.
Cases that settle through mediation are generally finalised significantly sooner than litigated disputes.
The financial consequences of separation are governed by two separate legal frameworks:
Failure to comply with payment orders can result in enforcement actions such as garnishee notices or property seizure.

Family Dispute Resolution (FDR) is a mandatory step in most parenting disputes. This process allows separating parents to negotiate agreements without litigation, guided by an independent mediator accredited under Regulation 58 of the Family Law (Accreditation) Regulations 2008.
Mediation offers advantages including:
If no agreement is reached, the mediator issues a Section 60I certificate, enabling either party to commence court proceedings.
Following divorce, both parents generally continue to hold shared parental responsibility unless the Court determines otherwise. They must consult on significant issues relating to:
If uncertainty arises about compliance or enforcement, parties can find family lawyer support to interpret court orders and take appropriate legal steps under the Family Law Act.

Understanding divorce and custody laws can be daunting. Below are direct answers to common legal queries drawn from Australian case experience.
A divorce is generally finalised within three months once filed, while custody disputes can take six to twelve months depending on complexity, mediation success, and court load.
The Court ensures proper arrangements exist for each child’s welfare before granting a divorce. Parenting matters are assessed separately based on the child’s best interests.
Expect costs for court fees, legal advice, and mediation. Contested cases are more expensive due to preparation and evidence requirements, while consent orders reduce expenses substantially.
Yes, except in cases of family violence, abuse, or urgency. A Section 60I certificate must usually be filed to show genuine attempts at dispute resolution before litigation.
Both parents retain legal responsibility for major decisions unless otherwise ordered. The child’s best interests remain the paramount consideration in all circumstances.
Navigating divorce and custody matters requires precise legal guidance, particularly where children, assets, or cross-jurisdictional issues are involved.
