The Family Law Act 1975 is a cornerstone of Australian family law, shaping how legal matters are handled in families across the nation. At Jameson Law, we often refer to the Family Law Act 1975 on AustLII to ensure we’re providing our clients with the most up-to-date legal advice.
This comprehensive legislation covers everything from property division to child custody, and has undergone several amendments since its inception. In this post, we’ll break down the key provisions of the Act and explain how they might affect you and your family.
What is the Family Law Act 1975?
The Family Law Act 1975 revolutionised family law in Australia. It introduced no-fault divorce, a significant shift from the previous fault-based system. This change allowed couples to separate without proving wrongdoing, making the process less adversarial and more focused on the welfare of all parties involved.
Scope and Purpose
The Act covers a wide range of family-related legal matters, including:
Divorce
Property settlement
Parenting arrangements
Spousal maintenance
Its primary purpose is to provide a framework for resolving family disputes fairly and efficiently, with a strong emphasis on the best interests of children.
One of the most practical aspects of the Act is its focus on alternative dispute resolution. It encourages families to resolve their issues outside of court whenever possible (which can save time, money, and emotional stress). For example, Section 60I of the Family Law Act 1975 mandates that parties must make a genuine attempt to resolve their disputes about children’s matters through Family Dispute Resolution before filing for parenting orders, unless there are exceptional circumstances such as family violence.

Major Amendments
Since its inception, the Family Law Act has undergone several significant amendments to keep pace with changing social norms and family structures.
One of the most notable changes came in 2009 with the introduction of provisions recognising de facto relationships. This amendment ensured that de facto couples, including same-sex couples, who separate after 1 March 2009, are entitled to the same legal rights as married couples under the Family Law Act.
Another important amendment was the expansion of the definition of family violence (now reflected in s4AB of the Act) to include emotional and financial abuse. This change has had a profound impact on how family law practitioners approach cases involving domestic violence, allowing better protection for vulnerable clients.
Guiding Principles
The Act is underpinned by several key principles that shape its application in Australian courts:
- The paramountcy principle: The best interests of the child must be the primary consideration in all decisions relating to children.
- Shared parental responsibility: This doesn’t necessarily mean equal time with each parent, but rather that both parents have an equal say in major decisions affecting the child’s life (such as education and healthcare).
- Maintaining meaningful relationships: The Act emphasises the importance of maintaining meaningful relationships between children and both parents, as well as other significant people in their lives, such as grandparents. However, this is always balanced against the need to protect children from harm.
In practice, these principles mean that when advising clients on parenting matters, the focus is on creating arrangements that prioritise the child’s wellbeing and foster positive relationships with both parents, while ensuring safety is never compromised.
As we move forward to explore the important provisions of the Family Law Act, it’s essential to understand how these foundational elements shape the specific legal processes and outcomes in family law matters.
Key Provisions of the Family Law Act
The Family Law Act 1975 contains several critical provisions that shape how family law matters are handled in Australia. These provisions cover a range of issues from property division to child custody, and understanding them is essential for anyone who navigates the family law system.
Property and Financial Matters
The Family Law Act takes a four-step approach when it comes to dividing property and financial assets after a relationship breakdown:
- We identify and value all assets and liabilities.
- We assess the contributions of each party (both financial and non-financial).
- We consider future needs.
- We determine if the proposed division is just and equitable.
It’s important to note that superannuation is treated as property under the Act. The Australian Institute of Family Studies reports that the average superannuation split in 2018 was 65% to the wife and 35% to the husband. However, each case is unique, and these figures don’t guarantee a specific outcome. (See AIFS and Services Australia — splitting super for general guidance.)
Parenting Arrangements
The Act places the best interests of the child at the forefront of all parenting decisions. Under section 60CA of the Family Law Act 1975, the best interests of the child are to be the paramount consideration of the court when making a parenting order. This doesn’t necessarily mean equal time with both parents. The Australian Institute of Family Studies found that only about 20% of children in separated families spend equal time with both parents.

The Act encourages parents to make decisions about their children together. However, if parents can’t agree, the court can make parenting orders. These orders can cover where a child lives, how much time they spend with each parent, and how parents make decisions about the child’s welfare. See the Court’s guide to parenting orders.
Spousal Maintenance and Child Support
Spousal maintenance is not automatic in Australia. The Act states that a person has a responsibility to support themselves as far as they can. However, if one party can’t meet their own reasonable needs, and the other party has the capacity to pay, the court may order spousal maintenance.
Child support, on the other hand, is governed by the Child Support (Assessment) Act 1989. This Act works in conjunction with the Family Law Act to ensure children receive financial support after their parents separate. The amount of child support payable is calculated using a formula that considers both parents’ incomes, the amount of time each parent cares for the child, and the costs of raising children. See Services Australia — Child Support.
Divorce and Separation
The Act introduced no-fault divorce in Australia. When the 1975 Family Law Act was passed, a ‘no-fault’ divorce clause was introduced. This means that for a couple to divorce, it needn’t be proven that either party was at fault. The only ground for divorce is the irretrievable breakdown of the marriage, demonstrated by 12 months of separation. It’s important to note that divorce is a separate process from property settlement and parenting arrangements. Parties can deal with these matters before, during, or after the divorce process.
Many people don’t realise that they can be separated while living under the same roof. This ‘separation under one roof’ can count towards the 12-month separation period required for divorce, but parties need to prove it to the court’s satisfaction. Guidance: Separation under one roof.
Understanding these key provisions of the Family Law Act is vital for anyone who deals with family law matters in Australia. However, family law can be complex, and every situation is unique. That’s why it’s always advisable to seek professional legal advice tailored to your specific circumstances. In the next section, we’ll explore the legal processes and procedures involved in family law matters, including dispute resolution, court proceedings, and enforcement of orders.
How the Family Law Act Handles Legal Processes
Family Dispute Resolution and Mediation
The Family Law Act 1975 prioritises Family Dispute Resolution (FDR) as the first step for most parenting disputes. In Australia, many separated parents avoid court to settle their custody disputes, with a significant proportion seeking assistance from family dispute resolution. This process involves a neutral third party who assists couples in discussing issues and reaching agreements. See the AGD guide to FDR and the Family Relationships Advice Line.

Mediation often serves as a cost-effective alternative to litigation. Costs vary by provider and eligibility for funded services; see Family Relationship Centres for options. It’s also faster, with many mediations resolved within a handful of sessions, while court proceedings can extend much longer.
Court Proceedings and Litigation
If FDR fails or proves inappropriate (such as in cases involving family violence), the matter may proceed to court. The Federal Circuit and Family Court of Australia handles most family law cases and triages risk early in proceedings.
Court preparation requires gathering all relevant documents, including financial records, communication logs, and any evidence supporting your case. The court process typically involves several stages:
- Filing an application
- Attending a first court event
- Interim hearings (if necessary)
- Compliance with court orders (such as attending parenting courses)
- Final hearing
Enforcement of Court Orders
Not everyone complies with court orders. The Family Law Act provides mechanisms for enforcing orders, including:
- Contravention applications
- Recovery orders for children
- Location and Commonwealth Information orders
In severe cases, the court can impose fines or even imprisonment for non-compliance. However, these are last resorts, and the court prefers less punitive measures where possible.
If you face a non-compliant party, document all instances of non-compliance thoroughly. This evidence will prove vital if you need to file a contravention application.
Appeals Process
If you believe the court has erred in your case, you may have grounds for appeal. However, appeals are complex and expensive, with success rates typically below 50%.
To appeal, you must file a Notice of Appeal within 28 days of the order being made. Appeals are usually heard by a Full Court of three judges. They focus on errors of law, not re-evaluations of evidence. See the Court’s guidance on appeals and review.
Before considering an appeal, seek expert legal advice. A legal professional can assess your case and advise on the likelihood of success, helping you make an informed decision about whether to proceed.
Final Thoughts
The Family Law Act 1975 has modernised Australian family dynamics since its inception. It introduced no-fault divorce and emphasised the best interests of children, encouraging many families to resolve issues outside of court. The Act continues to adapt to the increasing complexity of family structures, including blended families and same-sex partnerships.
The Family Law Act 1975 (as found on AustLII) provides a comprehensive framework for family law matters. However, its provisions can be complex and challenging to navigate without professional guidance. Each family’s situation is unique, and the Act’s application varies depending on individual circumstances.
