Navigating the financial aspects of separation can be complex, especially when it comes to ongoing financial support arrangements. Whether you’re recently separated or planning for the future, understanding the difference between spousal maintenance and child support is essential. If you’re seeking guidance from a family lawyer in Melbourne or elsewhere in Australia, knowing the basics of these two distinct legal concepts will help you prepare for discussions about your rights and responsibilities.
Key Takeaways
- Spousal maintenance supports a former partner who cannot meet their reasonable living expenses, while child support specifically covers a child’s needs
- Child support is calculated using a formula and administered by Services Australia, whereas spousal maintenance is discretionary and typically managed through court orders
- Both payments are separate from property settlements and require different application processes and evidence
- Professional legal advice is recommended to navigate the specific requirements of each payment type
What is spousal maintenance?
Legal definition in Australian family law
Spousal maintenance refers to financial support paid by one partner to another after a relationship breakdown. It applies to both married couples under the Family Law Act and certain de facto relationships, though eligibility requirements differ slightly between these relationship types.
Purpose and scope
The fundamental purpose of spousal maintenance is to provide financial support to a former spouse or partner who cannot adequately meet their own reasonable living expenses from their personal income or resources.
Types of spousal maintenance
Courts can order spousal maintenance as periodic payments (regular ongoing payments) or as a lump-sum order (a one-off payment). The type granted depends on individual circumstances and the financial positions of both parties.
Factors the court considers
When determining spousal maintenance, courts consider:
- Each party’s income, property, and financial resources
- Each party’s reasonable needs and expenses
- Earning capacity, age, health, and physical abilities
- Care responsibilities for children
- Length of the relationship and each person’s contributions
- Impact of the relationship on earning capacity
What is child support?
Legal framework and administration
Child support operates under a specific legislative framework administered primarily by Services Australia (Child Support). Parents can also make private child support agreements that can be registered with the agency.
Purpose
Child support aims to help with the costs of raising children and is specifically designed to cover a child’s day-to-day needs, including food, housing, clothing, education, and healthcare.
Who pays and who receives
Typically, the parent who has less care time (the non-primary carer) pays child support to the parent who has more care time (the primary carer). However, the actual payments depend on various factors, not just care arrangements.
How child support is organised
The child support formula takes into account:
- The percentage of care each parent provides
- The taxable income of both parents
- The number and ages of children
- The estimated costs of raising children
Duration
Child support generally continues until a child turns 18 or completes secondary education. In special circumstances, such as a child with a disability, support may continue beyond this age.
Key differences between spousal maintenance and child support
“The fundamental distinction is that spousal maintenance supports an ex-partner’s needs while child support is specifically for the benefit of the child – this difference affects everything from how each payment is calculated to how long it continues.” – Tonkin Legal
Primary objective
Spousal maintenance focuses on supporting a former partner who cannot meet their own needs. Child support specifically addresses the costs associated with raising children.
Who can claim
A former spouse or partner makes claims for spousal maintenance for their own benefit. Child support claims are made by a parent or guardian on behalf of the child.
Calculation method
Spousal maintenance amounts are discretionary and determined case-by-case, either by court assessment or mutual agreement. Child support uses a legislative formula applied by Services Australia.
Administration and enforcement
Spousal maintenance typically requires court orders, consent orders, or binding financial agreements, with enforcement through court mechanisms. Child support has administrative enforcement tools through Services Australia, including income withholding and tax return interception.
Duration and finality
Spousal maintenance may be temporary, periodic, or ongoing depending on circumstances and often ceases upon remarriage. Child support is usually tied to the child’s age or dependence status.
Relationship to property settlement
While both are separate from property settlement, spousal maintenance orders may be adjusted based on property settlement outcomes. Child support operates independently of property matters.
How amounts are calculated
Spousal maintenance calculation steps
Courts follow these general steps:
- Assess the financial needs of the applicant and whether they can meet these needs themselves
- Evaluate the respondent’s capacity to pay
- Balance these factors against the background of the relationship history
Child support formula basics
The child support formula considers both parents’ incomes after deducting a self-support amount, the percentage of care each provides, the number and ages of children, and whether either parent supports other children.
Example scenarios
For a couple with one child where the primary carer earns $40,000 and the other parent earns $80,000, child support might be around $12,000 annually. If the primary carer also needs spousal maintenance due to limited work capacity, the court would separately assess their reasonable needs against the other party’s capacity to pay.
How to apply and what evidence you need
Applying for spousal maintenance
You can negotiate an agreement directly, apply for consent orders if you agree, or seek court orders if necessary. You’ll need income statements, bank records, tax returns, expense details, and evidence of care responsibilities.
Applying for child support
Lodge an application with Services Australia or register a private agreement. You’ll need proof of income, care arrangements, and child details including birth certificates.
Enforcement options
For spousal maintenance, enforcement options include court-ordered garnishee of wages or contempt proceedings. Child support enforcement includes automatic withholding from wages, interception of tax refunds, and even international recovery in some cases.

Conclusion
Understanding the differences between spousal maintenance and child support is key to managing post-separation finances effectively.
