Understanding Child Support

Child support in Australia is primarily governed by the Child Support (Assessment) Act 1989 (Cth). The Department of Human Services calculates assessments using a statutory formula based on each parent’s income, care arrangements and the number of children.
Parents may rely on:

  • Administrative assessments issued by Services Australia
  • Limited child support agreements
  • Binding child support agreements

A binding child support agreement can provide greater certainty and flexibility but must comply with strict formal requirements, including independent legal advice.

Disputes may involve change of assessment applications, enforcement issues or court proceedings in the Federal Circuit and Family Court of Australia.

When You Need a Child Support Lawyer

Legal advice is important when:

  • You disagree with a child support assessment
  • Your financial circumstances have changed
  • You are seeking a private child support agreement
  • You are asked to sign a binding agreement
  • There are unpaid child support arrears
  • A departure or change of assessment is sought
  • The matter may proceed to court

Structured advice assists in managing financial exposure and compliance.

Our Legal Services for Child Support

We advise parents on structured support arrangements and disputes, including:

  • Child support assessments
  • Binding child support agreements
  • Limited child support agreements
  • Change of assessment applications
  • Enforcement proceedings
  • Court representation

We provide clear advice on statutory requirements and financial implications.

Our Approach to Child Support Matters

We begin by reviewing income details, care arrangements and the administrative assessment. Where appropriate, we advise on whether a private agreement would provide greater certainty or flexibility.

Binding agreements are prepared with strict compliance to statutory requirements, including independent legal advice certificates.

In disputed matters, we prepare detailed submissions addressing income, special expenses and capacity to pay. Where court proceedings are required, we provide structured representation focused on practical financial outcomes.

Our advice is measured and financially grounded.
