Child support and spousal maintenance

These are two separate things that people often run together. Child support is money for a child, worked out by Services Australia under a formula. Spousal maintenance is money for an adult who cannot support themselves, and it is decided under the Family Law Act.

You can be entitled to one and not the other. They are assessed differently, claimed differently and argued differently, and a matter that goes wrong usually went wrong because the two were treated as one.

What we help with

Situations we act in

We are commonly asked to help with:

  • A child support assessment that does not reflect what the other parent actually earns
  • Applying for a change of assessment where there are special circumstances
  • Negotiating a limited or binding child support agreement
  • Independent legal advice on a binding child support agreement someone else has drafted
  • School fees, medical costs and other expenses the formula does not cover
  • Maintenance for a child over 18 who is still studying or who has a disability
  • Spousal maintenance after separation, including where one partner left work to raise children
  • Urgent maintenance where someone has been left with no income at all

How we approach it

How Ben and Troy run a child support and spousal maintenance matter

Most of the value here is in knowing which route to take before you start.

Services Australia or the court, not both at random
Child support is administrative. Spousal maintenance and adult child maintenance are court applications. Bringing the wrong one is a common and avoidable expense, and we will tell you at the first conversation which forum your problem belongs in.
An assessment reflects the income it is given
The formula runs on each parent’s adjusted taxable income and on the care each provides. Where reported income does not match how someone is living, the answer is usually a change of assessment application rather than an argument, and it needs evidence rather than suspicion.
Spousal maintenance is a threshold, not an entitlement
The question is whether one person cannot adequately support themselves and whether the other has the capacity to help. There is no formula and no automatic payment. We will be straight with you about which side of that line you are likely to fall.
Agreements trade flexibility for certainty
A binding child support agreement locks in an amount and takes the formula out of the picture, which is useful when income is unpredictable and painful when circumstances change. Ending one is deliberately difficult. That is worth understanding before signing, not after.

Typical process

What usually happens, step by step

Every matter differs, but the shape is usually this.

  1. 01

    Working out which claim you actually have

    We separate the child support question from the maintenance question, and identify which is worth pursuing and in which forum.

  2. 02

    The financial picture

    Income, tax returns, business structures, living expenses and, for maintenance, what you reasonably need. For a change of assessment or a maintenance application this evidence is the case.

  3. 03

    Application or agreement

    That may be a change of assessment through Services Australia, a child support agreement negotiated between you, or an application to the court for spousal or adult child maintenance.

  4. 04

    Review when things change

    Care arrangements shift, incomes rise and fall, children finish school. Assessments follow those changes; agreements often do not. It is worth revisiting either when something significant moves.

Questions

Common questions

What is the difference between child support and spousal maintenance?

Child support is money towards the cost of raising a child, assessed by Services Australia under a formula. Spousal maintenance is money to support a former partner who cannot adequately support themselves, decided under the Family Law Act by agreement or by a court. They are separate claims with separate tests, and you can have one without the other.

How is child support worked out?

Services Australia applies a formula that takes in each parent’s adjusted taxable income, the proportion of care each provides, the number and ages of the children, and any other dependent children. Services Australia publishes an estimator, which is the sensible place to get a figure. What a lawyer adds is knowing when the assessment does not reflect reality and what to do about it.

The other parent’s income does not reflect how they live. What can I do?

You can apply for a change of assessment on the basis of special circumstances, which is the route for situations like income held inside a company or trust, or an earning capacity that is not being used. It runs on evidence rather than suspicion, so what matters is what you can actually show.

Does child support cover school fees and orthodontics?

Not specifically. The formula produces a single amount intended to cover the costs of raising a child, and it does not itemise private school fees, braces or extracurricular costs. Those are usually dealt with by agreement, or through a change of assessment where the circumstances justify it.

Am I entitled to spousal maintenance?

It depends on two things: whether you are unable to support yourself adequately, and whether your former partner has the capacity to pay. Age, health, care of children, and whether one of you stepped back from work during the relationship all feed into that. There is no formula and no standard amount.

Can I get support for a child who has turned 18?

Sometimes. Child support generally ends when a child turns 18 or finishes school, but the court can order adult child maintenance where a child is completing their education or has a disability. That is a court application rather than a Services Australia assessment.

Do we need lawyers for a child support agreement?

For a binding child support agreement, yes: both parents must receive independent legal advice and each must have a certificate confirming it. A limited agreement does not require advice but has different rules about when it can end. Which one suits depends on how much certainty you need and how stable the incomes are.

Is there a deadline for spousal maintenance?

Yes, and it catches people. If you were married, an application must generally be made within 12 months of your divorce becoming final. For de facto relationships it is two years from the date the relationship ended. After that you need the court’s permission to apply at all.
