As modern families evolve, so too must the legal systems that support them. Blended families—those where parents bring children from previous relationships into a new family unit—are increasingly common in Australia. With that in mind, recent amendments to the Family Law Act 1975 aim to better reflect the complexities and challenges these families face.

If you’re part of a blended family, it’s crucial to understand how these changes affect your legal rights, responsibilities, and parenting arrangements.

What Is a Blended Family Under Family Law?

A blended family typically includes a couple and their children from one or more previous relationships, and may also include biological children from the new relationship. In legal terms, this introduces additional dynamics regarding parenting responsibilities, custody arrangements, and the rights of step-parents or guardians.

The Family Law Act 1975 (Cth) governs these matters across Australia, and recent reforms—effective as of 2024—aim to clarify the legal standing of blended families in matters such as parenting orders and decision-making responsibility.

Key Changes Affecting Blended Families

Removal of the Presumption of Equal Shared Parental Responsibility One of the most significant reforms is the removal of the presumption of equal shared parental responsibility. Previously, the law assumed both parents should equally share decision-making duties, even in blended family contexts. This often created confusion for step-parents or guardians acting in a parenting role. Now, the court prioritises what is in the child’s best interests—not what’s “equal” or “shared.” This change provides more flexibility for blended family dynamics and may give step-parents greater practical input where appropriate.

Simplified Parenting Framework The revised legislation introduces a streamlined parenting framework, replacing confusing legal terms with clearer language. Instead of “live with” and “spend time with,” orders now refer more simply to “parenting time” and “parental responsibility.” This allows courts to tailor decisions to reflect the role of all caregivers—including step-parents, who may play an active and long-term role in the child's life.

Step-Parent Recognition Under the Family Law Act, step-parents do not automatically gain parental responsibility. However, the changes now allow courts to more easily grant parenting orders to step-parents who demonstrate a consistent and caring role in the child’s life. This gives blended families more legal certainty, especially in long-term relationships where the step-parent assumes day-to-day parenting responsibilities.

Impact on Parenting Arrangements and Custody

For blended families, parenting arrangements can become complicated, especially if multiple biological parents are involved. The revised legislation now requires the court to assess six key factors to determine the child’s best interests, including:

• The child’s safety
• The child’s views (where appropriate)
• The nature of relationships with parents and other carers
• The capacity of each person to meet the child’s needs
• Any family violence risks
• The benefit of maintaining stable arrangements

These factors allow the court to create more tailored custody arrangements that can include step-parents or other significant adults in a child’s life, when appropriate.

Guardianship and Financial Obligations

Blended family members often share financial responsibilities, even without legal guardianship. The reforms don’t automatically impose child support obligations on step-parents, but courts can still consider their financial contribution when assessing the overall care of the child.

If a step-parent wishes to formalise their role, they can apply for parenting orders or, in some cases, adoption, though this is a more complex process that requires both biological parents’ consent (except in limited circumstances).

Protecting Children from Harm: A Core Priority

In all decisions, the protection of the child from harm remains the highest priority. If a child is living in a blended family environment where family violence or emotional abuse is present—whether from a biological parent or step-parent—the courts will act swiftly to modify parenting orders.
