When people think about property settlement after separation, they often focus on who gets the house, the savings, or the superannuation. Debt tends to get less attention, yet it can have just as significant an impact on the final outcome. Whether you share a mortgage, hold joint credit cards, or one partner has personal loans, all of it needs to be addressed as part of the settlement process.
Debt is part of the asset pool
Under Australian family law, property settlement is not just about dividing assets. It is about dividing the entire financial picture of the relationship, which includes both assets and liabilities. Courts and lawyers refer to this as the "asset pool" or the "net asset pool." Debts reduce that pool. A couple with $800,000 in assets and $300,000 in liabilities has a net pool of $500,000, and that is what gets divided.
This means that before any split can be calculated, every debt needs to be identified and valued. That includes mortgages, car loans, personal loans, credit card balances, tax debts, business debts, and even informal loans from family members, if they are genuine obligations.
Joint debt vs individual debt
Not all debt is treated the same way in a settlement. The key distinction is whether a debt is joint (held in both names) or individual (held in one name only).
- Joint debt is owed by both parties to the lender, regardless of what any private agreement between the parties says. If one party agrees to take responsibility for a joint credit card but then fails to pay it, the lender can still pursue the other party. The family law settlement does not change the legal relationship with the lender.
- Individual debt may still be included in the asset pool if it was incurred for the benefit of the relationship. For example, a personal loan taken out to fund a family holiday or home renovation is likely to be treated as a shared liability, even if only one name is on it.
The court looks at the purpose of the debt, not just whose name is on it. This is an important nuance that surprises many people going through separation.
When debt is excluded from the pool
Some debts may be treated as the sole responsibility of one party. This is more likely when the debt was incurred after separation, for purely personal purposes, or where one party ran up debt recklessly or without the other's knowledge. Courts have discretion in these situations, and the outcome will depend on the specific facts.
Gambling debts, for instance, may be excluded from the joint pool if the court finds that the other party received no benefit from them. Similarly, a debt incurred to fund a new relationship after separation is unlikely to be treated as a shared liability.
How the mortgage fits in
The family home is often the most significant asset in a settlement, and the mortgage that goes with it is usually the most significant liability. How the family home is treated in property settlement depends on a range of factors, but the mortgage balance will always be deducted from the home's market value when calculating the net asset pool.
If one party keeps the home, they will typically need to refinance the mortgage into their sole name. This removes the other party's liability to the lender, which is important. Without a formal refinance, the departing party remains legally responsible for repayments even if the settlement order says otherwise. Lenders are not bound by family court orders.
Reaching an agreement on debt
Couples can agree on how to divide debt between themselves, either through negotiation, mediation, or consent orders filed with the court. A written agreement, particularly a binding financial agreement, can set out exactly who is responsible for which debts going forward. How property settlement works after separation in Australia involves a structured process, and getting legal advice before finalising any agreement about liabilities is strongly recommended.
It is not enough to agree between yourselves. If joint debt is involved, you will need to take formal steps with each lender to separate those obligations. This might mean closing joint accounts, transferring balances, or refinancing. Leaving joint financial products open after separation creates ongoing risk for both parties.
What courts consider when dividing liabilities
If the matter proceeds to court, a judge will consider a range of factors when deciding how liabilities should be allocated. These include:
- The contributions each party made to accumulating or reducing the debt
- The purpose for which the debt was incurred
- Each party's capacity to service the debt going forward
- Whether any debt was incurred recklessly or without consent
- The overall fairness of the settlement, taking both assets and liabilities into account
Courts have broad discretion and will look at the whole picture rather than treating debt in isolation. An experienced family lawyer can help you understand how a court is likely to approach your specific situation.
Getting the numbers right
Before any settlement can be finalised, a full and honest disclosure of all debts is required. This is a legal obligation in Australian family law proceedings. Hiding or understating liabilities can have serious consequences, including orders being set aside at a later date.
For guidance on how different types of assets and liabilities are valued for settlement purposes, see our article on how to value assets in a property settlement. Getting the numbers right from the start avoids disputes later and gives both parties a clearer picture of what a fair outcome actually looks like.
If you are facing a property settlement that involves significant debt, speaking with a family lawyer early is the most effective step you can take. The structure of any agreement, and the order in which steps are taken, can make a real difference to the financial outcome for both parties.
