We provide clear, tailored advice to help you understand your rights, obligations and options in relation to child support and adult child maintenance. We will assess your situation and recommend the best approach for your child support matter.

Child support after separation

After separation both parents continue to have a legal obligation to contribute to the financial support of their child. Depending on the circumstances, child support may be payable by one parent to the other, or by one or both parents to an eligible non-parent carer.

In Australia, child support is administered by Services Australia and is governed principally by the Child Support (Assessment) Act 1989 (Cth) (Act).

Child support may be dealt with through an administrative assessment or by entering into a private child support agreement. The most appropriate arrangement will depend on your family’s circumstances.

Administrative child support assessment

Child support is financial support paid by a parent to the other, or to an eligible non-parent carer. Child support is essential to ensuring that children’s needs are met regardless of their parents’ relationship status and living arrangements.

Either parent, or in some circumstances, an eligible non-parent carer, can apply to Services Australia for an assessment of the amount of child support payable.

Either parents can apply, regardless of whether they will be paying or receiving child support.

Services Australia applies a specific formula set out in the Act to determine whether child support is payable, who must pay it and the amount payable. Services Australia provides an online child support estimator that can give parents an indication of the amount that may be payable.

The child support formula generally takes into account several matters, including:

  • each parent’s income;
  • the amount of time each parent cares for the child;
  • any other children the parents are financially responsible for;
  • any other child support cases involving either parent; and
  • other relevant matters as provided by the Act.

Further information about administrative assessment and the child support estimators is available through Services Australia.

Private child support agreements

Parents are not always required to rely solely on an administrative assessment. As an alternative, parents may enter into a private child support agreement, such as a limited child support agreement or a binding child support agreement. These agreements can be long term or short term, and different legal requirements apply to each type of agreement.

A private child support agreement may give a family greater control over how financial support is provided. Depending on its terms and the type of agreement, it may address expenses such as:

  • school fees and related educational expenses;
  • private health insurance;
  • medical and dental expenses;
  • extracurricular activities;
  • tutoring and other agreed educational support; and
  • travel or other agreed expenses concerning the child.

An agreement can specify the amount, timing and method of payment. Depending on its terms, it may provide for periodic payments, payments of identified expenses or other forms of agreed support. A child support agreement may be submitted to Services Australia for acceptance and, depending on the arrangements, payments may be privately collected or collected through Services Australia.

Private child support arrangements may also be negotiated alongside broader parenting and property matters following separation.

Extension of child support through Services Australia after the child turns 18

Child support will normally end after a child turns 18. However, in some circumstances child support can be extended.

If a child turns 18 while undertaking full-time secondary education and there is a child support assessment in place, an application may be made by the receiving parent to Services Australia to extend the assessment until the end of that child’s school year. The application should ordinarily be made when the child is 17 and before the child turns 18.

Adult child maintenance

Adult child maintenance is different from an extension of child support through Services Australia.

An eligible person may apply to the Federal Circuit and Family Court of Australia for adult child maintenance orders. The court may make orders for adult child maintenance under section 66L of the Family Law Act 1975 (Cth), where the court is satisfied that maintenance is necessary:

  • to enable the child to complete their education; or
  • because of a mental or physical disability of the child.

Either or both parents, the child, a grandparent, or any other person concerned with the care of the child may apply for adult child maintenance orders, subject to requirements set out in the Family Law Act 1975 (Cth).

Depending on the circumstances, the court may order periodic payments, a lump sum payment and/or another form of financial support (such as to cover the child’s accommodation, food, medical or other necessary expenses).

Orders for adult child maintenance may operate for a fixed period or until further order. An order made to enable a child to complete their education, or because of a disability, ceases if the child ceases that education or ceases to have that disability. A child maintenance order also ceases if the child is adopted, marries, enters into a de facto relationship or dies.

Frequently asked questions

How is child support calculated in Australia?

Services Australia generally calculates child support using the statutory formula in the Child Support (Assessment) Act 1989 (Cth). The formula considers several matters including, but not limited to, each parent's income, the percentage of care provided by each parent, the costs of the children and the number and ages of the children, other dependent children and any other child support obligations. Services Australia provides access to a child support estimator on its website.

Does the amount of time my child spends with me affect child support?

Yes. Services Australia determines each parent's percentage of care and takes this into account when estimating the child support payable.

Can parents agree on child support privately?

Yes. Parents may agree on child support arrangements through a limited child support agreement or a binding child support agreement. Each type of agreement has different legal requirements, advantages and limitations. The appropriate option will depend on your circumstances and the arrangements you wish to put in place for your children.

Do I need a lawyer for a binding child support agreement?

Yes. Each party must receive independent legal advice before signing a binding child support agreement. The agreement must also contain the statements and legal certificates required by the Act. Without compliance with the statutory legal advice requirements, and other requirements prescribed by the Act, the agreement will not be a valid binding child support agreement.

Can a binding child support agreement be changed or terminated?

A binding child support agreement cannot simply be varied. If different arrangements are required, the existing agreement must be terminated in a way permitted by the Act. A court may also set aside a binding child support agreement in specified circumstances. It is important to obtain legal advice before attempting to change or end an existing agreement.

What happens to child support when my child turns 18?

Child support normally ends when a child turns 18. If the child will still be undertaking full-time secondary education, it may be possible to extend child support until the end of that school year. An application should generally be made when the child is 17 and before the child turns 18. Different requirements can apply where a child support agreement is in place.

Can a parent be required to support an adult child?

Yes, in limited circumstances. The court may make an adult child maintenance order where maintenance is necessary to enable a child who is 18 or older to complete their education or because of the child's disability. The court will consider the child's needs and the financial circumstances relevant to determining the appropriate contribution.

What can I do if child support is not being paid?

The available collection and enforcement options depend on the type of child support liability and how the payments are being collected. Services Australia has significant collection powers in relation to registered child support debts, and court-based remedies may also be available in appropriate circumstances. We can advise you about the options available and the most appropriate way to pursue unpaid child support in your circumstances.
