Child Support Disputes
When you separate from your partner, proper arrangements need to be made for the financial support of any children of the relationship. Today, most children are covered by the provisions of the Commonwealth Child Support Scheme. The Child Support (Assessment) Act sets out a formula for working out how much child support should be paid. This is known as “an Administrative Assessment”. The Child Support Scheme is administered by the Department of Human Services which is a branch of the Australian Taxation Office.
The Department of Human Services enables parents to make arrangements between themselves for the payment of child support. The parties should keep a proper record of what child support has been paid. The Department of Human Services has powers to take action to recover arrears of child support which includes the power to garnishee a parent’s wage or obtain the benefit of any income tax refunds or other monies due to be paid to the liable parent.
At Bateman Battersby Lawyers Penrith, our experienced team can assist you with all aspects of a child support dispute including:
- advising you as to how much child support you should receive or pay;
- providing guidance as to how you can prepare an application to the Department of Human Services;

FAQ
Legal questions
answered
Who is liable to pay Child Support?
Each of the parents of the child is liable to pay Child Support. Parents must be resident in Australia in order to be liable to pay Child Support in accordance with an administrative assessment by the Department of Human Services. There are special provisions in relation to parents who live overseas.
Can parents agree about Child Support?
It is not compulsory to have an administrative assessment by the Department of Human Services. Parents can enter into their own arrangements in relation to Child Support. Alternatively, the parents may enter into a written Child Support Agreement which is registered with the Department of Human Services.
How is Child Support calculated?
Child Support is calculated under a formula set out in the Child Support (Assessment) Act. The formula requires the liable parent to pay a percentage of their taxable income as Child Support.
How is Child Support collected?
The Department of Human Services prefers parents to make arrangements between themselves for the payment of Child Support. If the parties do not agree to do it this way, payments can be collected by the Department of Human Services. Sometimes it is collected from the liable parent’s employer out of their wage or salary.
