Child Support vs Spousal Maintenance Australia: Key Differences

After separation, many parents are confused about the difference between child support and spousal maintenance. Are they the same thing? Can you pay both? Who decides how much?

Side-by-Side Comparison

The short answer: they're completely different legal obligations, governed by different laws, with different eligibility criteria and payment structures.

Let's break down the key differences, how they work together, and what you need to know about each.

What is Child Support?

Child support is a mandatory financial contribution

Child support is calculated using your Adjusted Taxable Income (ATI), care percentage, and the number and ages of children. The formula is standardized—everyone with the same circumstances pays the same amount. Learn more about router.push('/blog/how-to-calculate-child-support')}> how to calculate child support

How to Apply for Each

Yes, spousal maintenance is the Australian legal term for what is called alimony in other countries like the United States. Australia does not use the term "alimony" in legislation—it is referred to as spousal maintenance under the Family Law Act 1975.

Spousal maintenance duration is determined by the court and varies by case. It can be temporary (until the recipient becomes self-supporting), for a fixed period (e.g., 2-5 years), or in rare cases, indefinite. It typically ends if the recipient remarries or enters a de facto relationship, or if circumstances change significantly.

Common Misconceptions

Yes, if you were in a de facto relationship. The Family Law Act 1975 covers both married couples and de facto couples (including same-sex couples). You must have been in a de facto relationship for at least 2 years, or have a child together, or made substantial contributions to the relationship.

Yes. If you receive a significant property settlement, the court may decide you don't need spousal maintenance (or need less). Conversely, if you receive little or no property, you may have a stronger case for spousal maintenance. The court considers your overall financial position, including property, superannuation, and income.
