Spousal Maintenance & Child Support

Family Law

Key Takeaway

Spousal maintenance and child support are two separate but related financial obligations that can arise after separation.

Spousal maintenance and child support are two separate but related financial obligations that can arise after separation. Spousal maintenance is the ongoing financial support that one partner pays to the other after separation if the recipient cannot adequately support themselves due to circumstances such as age, ill health, caring for children, or limited earning capacity. The obligation to pay spousal maintenance arises under the Family Law Act 1975 (Cth) and is not automatic — it depends on the financial circumstances of both parties. Child support, on the other hand, is the financial contribution that parents make towards the costs of raising their children. In Australia, child support is primarily administered by Services Australia (the Child Support Agency) through a formula-based assessment that considers both parents' incomes and the care arrangements for the children. While spousal maintenance and child support are related, they are assessed and enforced separately, and you can apply for one without the other.

For spousal maintenance claims in Queensland, the court must first be satisfied that the applicant is unable to support themselves adequately for any of a range of reasons, including having care and control of a child under 18, age or physical or mental incapacity, or any other reason that affects their earning capacity. The court then considers whether the respondent has the capacity to pay maintenance. If both criteria are met, the court can order periodic payments or a lump sum. Spousal maintenance is typically limited in duration — the goal is to provide support while the recipient takes steps to become self-sufficient, unless there are circumstances that make self-sufficiency unlikely. For child support, the formula used by Services Australia takes into account both parents' taxable incomes, the number of children, the percentage of care each parent provides, and the costs of children based on government-determined tables. Parents can also enter into binding child support agreements that depart from the formula, provided certain requirements are met. Child support payments are generally compulsory and enforceable through the Child Support Registrar.

Spousal Maintenance Claims and Eligibility

A spousal maintenance claim arises under section 72 of the Family Law Act 1975, which imposes a duty on each party to a marriage or de facto relationship to support the other party if they are unable to support themselves adequately. To succeed in a spousal maintenance claim, the applicant must demonstrate that they cannot meet their reasonable living expenses from their own income or assets, and that the respondent has the financial capacity to pay maintenance. Factors that affect the applicant's ability to support themselves include caring for young children, age, physical or mental disability, lack of recent workforce participation, limited employment skills, and other circumstances that impact earning capacity. The court will consider the standard of living that the parties enjoyed during the relationship and whether the applicant can maintain a reasonable standard of living post-separation. Spousal maintenance applications should be made as soon as possible after separation, as delays can affect the outcome. In Queensland, the Federal Circuit and Family Court of Australia has jurisdiction to hear spousal maintenance matters, and the court can make interim orders for urgent maintenance while the final application is pending.

Child Support Assessments Through Services Australia

Child support in Australia is primarily assessed and managed through Services Australia (formerly the Child Support Agency). The formula used to calculate child support takes into account the taxable incomes of both parents, the number of children, the age of the children, the percentage of care each parent provides, and the cost of children as determined by government tables. The parent who has the majority of care (usually 65% or more) is generally the parent entitled to receive child support, while the other parent is the paying parent. However, if care is shared equally (50/50 or close to it), neither parent may be required to pay child support to the other. Parents can also enter into a binding child support agreement that departs from the formula, provided the agreement is in writing and signed by both parties. If a party is not satisfied with the child support assessment, they can apply to Services Australia for a change of assessment on specific grounds, such as that the assessment does not reflect the parents' actual income or that there are special circumstances affecting the costs of the children. Objections to decisions can be lodged, and ultimately the matter can be reviewed by the Administrative Appeals Tribunal.

Duration and Variation of Maintenance Orders

Spousal maintenance orders are not intended to provide indefinite financial support. The court will usually make an order for a fixed period, giving the recipient time to become self-sufficient through retraining, education, or workforce re-entry. In cases where the recipient is unlikely to ever become self-sufficient — for example, due to permanent disability or caring for a child with a long-term disability — maintenance may be ordered for an extended period or indefinitely. Spousal maintenance orders can be varied or terminated if there is a significant change in circumstances. Common reasons for variation include a change in the payer's income, the recipient being able to support themselves, remarriage of the recipient, or the death of either party. Child support assessments are reviewed annually by Services Australia based on updated income information. If a parent's income changes significantly, either parent can apply for a change of assessment. Child support orders generally continue until the child turns 18, though they can extend to age 18 or beyond if the child is in full-time secondary education or has a disability. Parents can also agree to extend child support beyond the usual duration through a binding child support agreement.

Spousal Maintenance & Child Support FAQs (Queensland Law)

What is the difference between spousal maintenance and child support in Queensland?

At our firm, we help clients with spousal maintenance claims. Spousal maintenance is financial support paid by one former partner to the other after separation, based on the receiving party's inability to adequately support themselves due to factors such as age, caring for children, or limited earning capacity. Child support is a separate payment for the costs of raising children, calculated by Services Australia using a formula based on both parents' incomes and care arrangements. Spousal maintenance is not automatic and requires a court order or agreement, while child support is formula-based and compulsory. You can pursue one without the other, and they are assessed and enforced through different legal frameworks.

How is child support calculated in Queensland?

Child support in Queensland is assessed by Services Australia. Our team helps parents understand and dispute child support assessments. Child support in Queensland is calculated by Services Australia using a formula that considers both parents' taxable incomes, the number and ages of children, and the percentage of care each parent provides. The cost of children is determined by government tables. For the 2024-2025 financial year, the self-support amount (the amount each parent can earn before their income is assessed for child support) is approximately $35,131. The parent with the majority of care (65% or more) generally receives child support from the other parent, unless care is shared equally. Parents can also enter into binding child support agreements that depart from the formula.

Can I apply for spousal maintenance after divorce in Queensland?

Yes, we can help you apply for spousal maintenance after divorce in Queensland. However, strict time limits apply. An application for spousal maintenance must generally be made within 12 months of the divorce becoming final. For de facto couples, the time limit is 2 years from the date of separation. If you miss these time limits, you must seek the court's permission to apply out of time, which requires demonstrating hardship. It is advisable to seek legal advice and make any spousal maintenance application as soon as possible after separation.

What factors does the court consider in a spousal maintenance claim in Queensland?

At our firm, the court considers two main questions in a spousal maintenance claim. First, is the applicant unable to support themselves adequately due to factors such as caring for a child under 18, age or physical/mental incapacity, or any other reason affecting their earning capacity? Second, does the respondent have the financial capacity to pay maintenance? The court also considers the standard of living during the relationship, the duration of the marriage or de facto relationship, and each party's financial resources including income, assets, and superannuation. Spousal maintenance is generally limited in duration to allow the recipient time to become self-sufficient.

Can child support be varied in Queensland?

Yes. Our team can help. Child support can be varied. If your circumstances change significantly — such as a substantial change in income, changes in care arrangements, or special needs of a child — you can apply to Services Australia for a change of assessment. Grounds for a change of assessment include that the assessment does not reflect the parents' actual income, that the costs of the children are significantly affected by special needs, or that there are high contact costs. Parents can also enter into a binding child support agreement that departs from the formula. If not satisfied with a decision, you can lodge an objection and ultimately seek review by the Administrative Appeals Tribunal.
