Understanding Your Child Support Rights and Obligations

Knowing Where You Stand

Whether you are the parent making child support payments or the parent receiving them, understanding your rights and obligations under the Australian system is fundamental. Many disputes arise not from genuine disagreements about the amount, but from misunderstandings about what the system requires, what it allows, and where the boundaries lie.

This guide sets out the key rights and responsibilities for both sides of the child support equation, along with the review and complaint mechanisms available when things go wrong.

Rights of the Paying Parent

Parents who make child support payments have several important rights under the Child Support (Assessment) Act 1989 and related legislation:

Right to an Accurate Assessment

You have the right to a child support assessment that is based on correct information — your actual income, the correct care percentage, and the right number of children. If any of these inputs are wrong, your assessment will be wrong, and you have the right to have it corrected.

Right to Object and Review

If you disagree with any decision made by Services Australia — including the assessment amount, a care determination, or an income decision — you can lodge an internal objection within 28 days (or 90 days in some circumstances). If the objection is unsuccessful, you can escalate to the Administrative Review Tribunal (ART) for an independent review.

Right to Lodge an Income Estimate

If your income has decreased since the last tax return used for the assessment, you can lodge an estimate of your current income. Services Australia will use this estimate for the remainder of the assessment period. Be aware that if your actual income turns out to be higher than estimated by more than 10%, you may be required to pay the difference plus a penalty.

Right to Apply for a Change of Assessment

If special circumstances mean the standard formula produces an unjust result, you can apply for a change of assessment under one of the ten prescribed "reasons" in the legislation. Common reasons include high costs of maintaining contact with your child, the receiving parent's income not being properly captured, or the need to support a new dependent.

Right to Credit for Non-Agency Payments

If you make payments directly to the other parent or for the child's benefit (such as school fees or health insurance), you can apply to have these credited against your child support liability, provided they meet the criteria for prescribed non-agency payments.

Rights of the Receiving Parent

Right to Receive the Assessed Amount

You are entitled to receive the full amount of child support as assessed by Services Australia, paid on time. If the paying parent falls behind, you have the right to request that the agency take enforcement action.

Right to Switch to Agency Collect

If you are currently on private collect and the other parent is not paying, you can switch to agency collect at any time. Once on agency collect, Services Australia assumes responsibility for collecting the payments and can use its enforcement powers.

Right to Request a Review of the Payer's Income

If you believe the paying parent's income is higher than what is being used for the assessment — for example, because they are self-employed, have recently changed jobs, or appear to have a lifestyle inconsistent with their declared income — you can request that Services Australia investigate.

Right to Apply for a Change of Assessment

Receiving parents can also apply for a change of assessment. Common grounds include the paying parent having financial resources not reflected in their taxable income (such as assets, trust distributions, or undeclared income) or special needs of the child that result in higher costs.

Obligations Common to Both Parents

The child support system imposes several obligations on both the paying and receiving parent:

• Provide accurate information. Both parents must provide truthful and complete information to Services Australia. Providing false information can result in penalties.
• Lodge tax returns. Services Australia uses ATO data to determine income. Failure to lodge tax returns can result in a provisional income being used, which may not reflect your actual position.
• Notify changes in care. If the care arrangements for the child change, both parents should notify Services Australia so the care percentage can be updated.
• Comply with assessments and agreements. Once an assessment is made or an agreement is registered, both parties are legally obligated to comply with its terms.

The Objection and Review Process

If you disagree with a Services Australia decision, the review pathway follows a clear sequence:

1. Internal objection — lodge within 28 days of the decision (90 days for some decisions). A different officer reviews the matter afresh.
2. Administrative Review Tribunal (ART) — if the objection is unsuccessful, you can apply to the ART for an independent review. The tribunal is not bound by the original decision and considers the matter anew.
3. Court appeal — in limited circumstances, a decision of the ART can be appealed to the Federal Circuit and Family Court on a question of law.

At each stage, you have the right to provide evidence, make submissions, and be heard. Having experienced support through this process can make a meaningful difference to the outcome.

Common Misconceptions

Several persistent myths about child support rights lead to unnecessary conflict between parents:

• "I can stop paying if I do not see my child." False. Child support and parenting time are separate legal matters. Non-payment because of access disputes can result in enforcement action and arrears.
• "The other parent has to prove how they spend child support." False. There is no legal obligation to account for how child support is spent. The payment is a contribution to the overall cost of the child's care.
• "Child support ends automatically when the child turns 18." Mostly true, but arrears accumulated before the child turns 18 remain payable. The debt does not expire.
• "I cannot change the assessment once it is made." False. Assessments can be changed through objections, change of assessment applications, income estimates, and care percentage updates at any time.
