What happens to the house when you have children?

Parenting and property settlement are separate processes

This is one of the most commonly misunderstood aspects of separation in Australia. The parenting arrangements — where the children live, how time is shared — are governed by Part VII of the Family Law Act. Property settlement is governed by Part VIII. They are separate legal processes with separate considerations.

The fact that you have primary care of the children does not automatically entitle you to keep the family home. And the fact that you are not the primary carer does not mean you lose your property entitlement.

What children do affect is the property settlement, through the future-needs assessment — specifically, how primary care of children factors into the adjustment that may be made to the overall split percentage.

How children affect the property split

Step 3 of the property settlement framework — the future-needs adjustment — explicitly recognises primary care of children as a factor. A parent who has primary care of young children is likely to have:

• Reduced capacity to earn full-time income, at least in the short to medium term
• Higher day-to-day expenses related to the children’s care
• Greater reliance on the asset settlement for financial stability

Courts may adjust the split percentage upward for the primary carer to reflect these realities. This is not a fixed formula — it depends on the ages of the children, the income situation of both parties, the care arrangements, and all other circumstances.

Importantly, this adjustment is applied to the total pool — not specifically to the house. A primary carer receiving a higher share might take that as additional equity in the house, as additional super, or as a mix.

The housing stability argument

One argument sometimes made in negotiations is that children need stability and continuity in their home environment, and that disrupting their primary residence adds stress to an already difficult situation. Courts are sometimes sympathetic to arguments about maintaining children’s routines and connections (school catchment, proximity to friends and activities).

However, this argument does not override the property framework. It is one factor among many and does not guarantee that the primary carer keeps the house. A court will still consider whether the primary carer can actually service the mortgage independently, or whether keeping the house is financially sustainable for them.

What if you can’t afford the mortgage alone?

This is a real and practical constraint. Even if there is a strong argument for the primary carer keeping the house, they need to be able to refinance the mortgage in their own name. Lenders will assess their income independently. If this is not viable, the practical options are:

• Sell the property and use the proceeds to find more affordable housing
• Defer the sale (by agreement) until the children reach a certain age or circumstance, then sell and divide — this is sometimes called a “Mesher order” approach
• One party buys out the other’s equity with cash sourced from another asset (such as super)

Each of these has implications for both parties that need careful consideration. The calculator can help you model these scenarios.

Children’s views and the property

In parenting matters, the views of children (particularly older children) can be relevant. In property settlement matters, children’s views are not directly considered. Property settlement is between the adults, not the children.

Child support and property settlement

Child support and property settlement are also separate systems. Child support is assessed through the Child Support Agency (Services Australia) using an administrative formula, or can be agreed privately. It does not form part of the property settlement asset pool. Do not conflate the two — they have different rules, different timeframes, and different enforcement mechanisms.
