Divorce and property settlement in Australia: how the family home gets split

Whose name is on the title doesn't decide who keeps the house. Under the Family Law Act 1975, the Family Court treats every property owned by either spouse, jointly or solely, as part of one single asset pool. A house bought before the marriage and still in one party's name is in the pool. A unit inherited mid-marriage is in the pool. The investment flat held in a discretionary trust is, in practice, often in the pool too. The split that follows has very little to do with the deed and a great deal to do with what each party brought in, what each party did during the relationship, and what each party will need next.

The four-step asset-pool process

The Family Court works through a four-step framework on every contested property matter. Most settlements that never reach a contested hearing still follow the same logic, because the framework is what lawyers and mediators are bargaining toward.

• Step 1, identify and value the asset pool. Real estate, superannuation, savings, business interests, shares, vehicles, and debts owed to or by either party. Property is valued by sworn valuation, not market opinion. Super balances come from the latest fund statement.
• Step 2, assess contributions. Financial contributions (deposit, mortgage payments, inheritance, earnings), non-financial contributions (renovations, unpaid labour in a business), and contributions as homemaker and parent. The court gives explicit weight to non-financial contributions; the parent who stayed home is not assumed to have contributed nothing.
• Step 3, adjust for future needs. Age, health, earning capacity, who has primary care of the children, and the period of any post-separation parenting. The party with the lower earning capacity or primary care of young children typically receives a 5% to 15% adjustment in their favour.
• Step 4, check the result is just and equitable. The court sanity-checks the proposed split against the whole picture and can adjust if it produces an outcome that looks procedurally fair but lands badly on one party.

Real estate in the asset pool

Equity is what goes into the pool, not market value. A house worth $1.2M with a $300k mortgage contributes $900k of net equity. The mortgage is a joint debt in the pool whether it sits on one name or two. Investment properties, holiday houses, and vacant land all enter on the same basis. Recent registered valuations carry more weight than agent appraisals; for contested matters a single jointly-instructed valuer is the norm, and both parties share the cost.

Three main options for the family home

Once the pool is agreed, the question becomes what happens to the bricks. Three patterns cover the vast majority of settlements.

• Sell and split the proceeds. Clean break, no ongoing financial entanglement. Agent commission, marketing, and conveyancing come off the gross sale price before the split, and capital gains tax applies on any non-PPR property on the standard apportionment rules. For most family homes the main residence exemption wipes out the CGT entirely; the main residence CGT exemption piece walks through the edge cases.
• One party keeps the home (a buyout).Party A refinances the existing mortgage into their sole name and pays Party B a cash settlement equal to B's share of the equity. Stamp duty on the transfer is exempt provided the transfer happens under a court order, consent order, or binding financial agreement. CGT is rolled over under Section 126-15 of ITAA 1997, meaning Party A inherits B's share of the original cost base and acquisition date rather than triggering a capital gain on the transfer.
• Defer the sale until the children are older. The court can order that the primary carer remains in the home with the children until a trigger event (youngest child turns 18, remarriage, sale by agreement). The non-resident spouse's share is preserved as a charge over the title. These orders are rarer than they used to be because they lock both parties into a long financial entanglement, but they remain useful where selling immediately would force a school change or where the market timing is genuinely punitive.

The stamp duty exemption that depends on paperwork

Every state and territory exempts transfers of property between spouses (married or de facto) from stamp duty when the transfer is made under a Family Court order, consent order, or binding financial agreement. Section 90L of the Family Law Act provides the federal hook; the state revenue offices apply the exemption through their own duties acts. The exemption is large. A transfer of a half-share in a $1.2M house carries roughly $25,000 to $30,000 of duty in most states at full rate; the exemption wipes it.

The trap is that the exemption only applies if the transfer is made under one of those instruments. A private handshake agreement, a separation deed drafted by a generalist solicitor, or a transfer signed before any consent orders are filed will attract full duty. The cost of a consent-order filing is a few thousand dollars; the duty saved usually pays for it ten times over. Run the duty number through the stamp duty calculator before deciding whether a quick handshake is really cheaper.

CGT roll-over: the trap on investment properties

Section 126-15 of ITAA 1997 rolls over CGT on property transferred between spouses under a court order or BFA. The transferring spouse doesn't recognise a capital gain. The receiving spouse inherits the original cost base and the original acquisition date, and pays CGT only when they eventually sell. For the family home this is usually moot because the main residence exemption applies anyway. For an investment property it is decisive.

Without a qualifying instrument, the transfer is treated as a disposal at market value. A spouse transferring their half of an investment unit bought for $400k and now worth $700k can find themselves with an immediate $150k capital gain on their share, and a tax bill in the $30k to $50k range in the same year as the relationship breakdown. The roll-over fixes that. Property settlements that ignore CGT and focus only on stamp duty regularly leave money on the table.

A worked example: $1.2M house, two parties, primary carer

Anna and Ben separate after twelve years of marriage. They agree to value their pool as follows: family home $1.2M with a $300k mortgage (so $900k net equity), $200k in Anna's super, $200k in Ben's super. Total pool: $1.3M. Anna is primary carer of two school-aged children and works part-time; Ben works full-time. After contributions (broadly equal) and a future-needs adjustment in Anna's favour, the agreed split is 55/45 to Anna.

Anna's share: 55% of $1.3M = $715k. Ben's share: $585k. Anna wants to keep the house so the children stay in the local school. She refinances the existing $300k mortgage into her sole name and the bank approves on the basis of her post-settlement income plus child support. She then needs to pay Ben enough to bring his total entitlement up to $585k.

Ben already retains his $200k super. He receives Anna's $200k super by way of a super-split order, taking him to $400k. Anna needs to pay him a further $185k in cash. She draws this from a redraw on the refinanced mortgage. End state: Anna holds the $1.2M house with a $485k mortgage ($300k original plus the $185k cash settlement) plus zero super, worth $715k net plus the roof over her family; Ben holds $400k of super plus $185k of cash. The numbers are illustrative; every real settlement adjusts for what each side actually wants, the bank's view of serviceability, and the children's arrangements.

Binding Financial Agreements vs consent orders

A Binding Financial Agreement (BFA) is a private contract between the parties, negotiated without the court. Each party must receive independent legal advice and the lawyer must sign a certificate to that effect. BFAs are faster and cheaper than litigation, can be made before or after separation, and attract the same stamp-duty and CGT concessions as a court order. The risk is procedural: BFAs are challenged successfully in the Family Court in roughly 10% to 15% of cases on grounds such as defective legal advice, duress, or non-disclosure of assets. A poorly-drafted BFA is worse than no agreement at all.

Consent orders are an agreement between the parties, drafted as proposed court orders and lodged with the Family Court for approval. A registrar reviews the orders and signs them off without a contested hearing if they appear just and equitable. Consent orders are typically much harder to overturn than a BFA because the court has already passed judgment on them. For most amicable separations involving real estate, consent orders are the safer instrument; the cost is a few thousand dollars more than a BFA and the certainty is considerably higher.

What the court won't do

Three common misconceptions about Family Court power are worth flagging. The court won't order the parties to sell to a specific buyer at a specific price; market mechanics are left to the parties and their agent. The court can order a sale and appoint a trustee for sale if the parties can't agree, but the buyer and price are decided by the market. The court won't split a super fund that doesn't permit splitting; super-splitting requires a flagging notice served on the trustee and the fund's administrative cooperation, and some self-managed and older defined-benefit funds throw up practical obstacles. The court won't rewrite a registered mortgage; the bank's security interest survives the settlement intact, and a refinance into sole name requires the bank's independent credit approval.

Selling while separated

If the parties agree to sell rather than buy each other out, a few practical issues come up early. Both spouses must sign the listing agreement and the contract of sale; one party can't unilaterally list a jointly-owned property. Agent commission is deducted from gross sale proceeds before the split, so the percentage agreed with the agent affects both parties equally; the agent commissions piece covers the typical ranges. Capital gains tax on a non-PPR property is apportioned by ownership period, and each party reports their share of the gain on their own return. Marketing costs, conveyancing, and any pre-sale repairs come off the top by default; agree in writing how each is funded before the property is listed, because trying to negotiate these allocations after settlement is the fastest route to a contested hearing.

Where this fits

Property settlement is the largest financial transaction most separating couples will go through, and the legal instruments that govern it (court orders, consent orders, BFAs) carry massive tax consequences that aren't always obvious to either party at the time. The stamp-duty exemption and the CGT roll-over only apply if the transfer is made under one of those instruments; a handshake settlement signed at the kitchen table can cost tens of thousands of dollars in avoidable duty and tax. Get independent legal advice early, get a sworn valuation before negotiating numbers, and model both the sale option and the buyout option with real figures rather than rough approximations. The cost of doing it properly is small next to the cost of doing it wrong.
