Child support lawyers in Newcastle

Advice on Child Support Agency assessments, private and binding agreements, enforcement and changes of assessment.
Separation, Family & Relationships

Child support is the financial contribution each parent makes to the cost of raising their children after separation. It is usually managed by the Child Support Agency (through Services Australia) using a set formula based on each parent’s income, the cost of children, and how much time the children spend with each parent. Parents can also make their own private agreements. We advise on child support from our offices in Newcastle, for clients across the Hunter and nationally.

How is child support calculated?

The Child Support Agency (through Services Australia) uses a formula that takes into account each parent’s adjusted taxable income, the estimated cost of children (based on income and the number and age of the children), and the percentage of nights each parent cares for the children. It produces an annual amount paid in instalments. Services Australia has an online estimator, but for your specific situation, legal advice is worthwhile.

FAQs

The Child Support Agency (through Services Australia) applies a formula based on each parent’s adjusted taxable income, the cost of children (from tables based on income, number and age of children), and the share of nights each parent cares for the children. It produces a yearly figure paid in instalments. An online estimator gives a guide, but advice helps with your specific circumstances.

Yes. An informal arrangement is flexible but not legally enforceable. A limited child support agreement must be at least the Services Australia assessment and can be ended after three years. A binding child support agreement can be for any amount or a lump sum, but both parents must get independent legal advice first, and it is harder to change.

Where child support is managed by Services Australia, it has strong powers: employer withholding, garnishing bank accounts, intercepting tax refunds, departure prohibition orders, and registering the debt. For private arrangements or court orders outside the system, you may need to apply to court to enforce. Get advice quickly, as arrears build fast.

Yes. Either parent can apply for a change of assessment for reasons such as a significant change in income, a change in care, or special circumstances, and assessments update when income or care changes. Parents can also agree a new amount. Changes usually take effect from when you notify Services Australia, so act promptly.
