Who is responsible for debts after separation? The answer is more complicated — and more fixable — than most people expect

How debts sit in the property pool

When a couple separates, the Family Law Act 1975 requires the court (or parties themselves) to identify the full property pool. That pool includes every asset — and every liability — that exists at the time of settlement, regardless of whose name it is in or when it was created.

The process works like this: all assets are valued, all debts are listed, and the debts are deducted from the assets to give a net pool. It is that net figure that is divided between the parties, not just the assets side of the ledger.

This means a couple with a $800,000 house, $150,000 in super, and $250,000 in mortgage debt is not dividing $950,000 — they are dividing a net pool of $700,000. If one party takes the house, they also take responsibility for the mortgage, and the other side receives a greater share of other assets (or a cash equalisation payment) to balance the split.

How debts enter the property pool — worked example

Item	Value / Balance	Notes
Family home	$850,000	Joint names
Superannuation (combined)	$180,000	Two accounts
Savings	$30,000	Joint account
Total assets	$1,060,000
Mortgage	−$390,000	Joint loan
Credit card (joint)	−$12,000	Balance at separation
Car loan (one party)	−$18,000	Loan in one name, car in pool
Net pool	$640,000	This is what is divided

Not every debt automatically enters the pool. Gambling debts, debts incurred to fund an extramarital relationship, or debts accumulated after the parties genuinely separated may be treated differently, particularly if the other party had no benefit from them.

Joint debts vs debts in one name

The distinction between joint debts and sole-name debts matters for two separate reasons: the settlement calculation, and what happens to your credit file.

Joint debts are accounts where both parties signed as borrowers — most home loans, many credit cards, some car loans. Both signatories are fully liable to the lender regardless of what the settlement agreement says. If the party who agreed to service the debt stops paying, the lender can pursue the other party for the full balance.

Sole-name debts are accounts where only one person signed. They still enter the property pool if the debt was incurred for a shared purpose (renovations, a family holiday, covering joint living costs) — but the lender's contract is with the named borrower only. The settlement can still assign responsibility, but the non-signing party's credit is not directly at risk.

Joint vs sole-name debts in property settlements

Debt type	Both liable to lender?	Enters pool?	Risk if other party doesn't pay
Joint mortgage	Yes	Yes	Default, credit impact, possible repossession
Joint credit card	Yes	Yes	Late payments on your credit file
Sole-name loan (joint purpose)	No	Usually yes	Low — lender cannot pursue you
Sole-name loan (personal)	No	May be excluded	Low — lender cannot pursue you
Guarantor loan	Conditionally	Yes	High if primary borrower defaults

The FCFCOA duty of disclosure process requires both parties to disclose all debts, not just joint ones. Hiding or understating liabilities is a serious issue in family law proceedings and can lead to orders being set aside.

The family home mortgage

For most separating couples, the mortgage is the largest single liability. There are four common outcomes:

1. One party buys out the other — the buying party refinances the loan into their sole name, paying out the other's equity. The leaving party is removed from the mortgage and the title. This is the cleanest outcome but requires the buying party to qualify for the loan alone.
2. The property is sold — the sale proceeds pay out the mortgage, and any remaining equity is divided. Simple, but it may mean both parties need to find new accommodation.
3. Both parties remain on the mortgage — an interim arrangement while a longer-term plan is reached. This works only if both parties can cooperate on repayments; it should have a clear end date built in (for example, "until the youngest child finishes secondary school").
4. One party occupies, the other pays rent — rare and legally complex, but sometimes used to keep children in the family home for a period.

Where one party cannot immediately refinance, a consent order can set a timeline — for example, requiring the property to be sold if a refinance has not occurred within 12 months. This protects the party whose name remains on the mortgage from an open-ended liability.

Joint and individual credit cards

Credit card debt is one of the most common flashpoints in property settlements. A few principles that apply in Australia:

Balance at the date of separation — the property pool is generally assessed at the date of settlement, not the date of separation. If one party continues using a joint card after separation for personal expenses, the other party can argue those post-separation debts should not be shared equally (or at all).

Freezing or closing joint accounts — either party can generally request that a lender reduce the credit limit or freeze new transactions on a joint account, though the lender is not obliged to agree. A solicitor's letter or interim order from the court can assist.

Secondary cardholders — if you were a secondary cardholder (not a joint account holder), you are not legally liable for the balance. Only the primary account holder is.

The Federal Circuit and Family Court of Australia has noted in many cases that the treatment of credit card debt depends heavily on how the card was used and for whose benefit. A card used entirely for household groceries and school fees is treated differently to one used for one party's personal expenditure after the relationship broke down.

Dividing debts: the practical framework

There is no rule that debts must be split 50/50. The Family Law Act 1975 gives the court (and by extension, mediating parties) broad discretion to reach a "just and equitable" outcome. In practice, that means looking at:

• Who incurred the debt and for what purpose — a home loan taken for the family property is treated differently to a personal loan for one party's business venture.
• Each party's capacity to service the debt — a party on a significantly lower income may receive a larger share of assets and a smaller allocation of debt.
• Whether the debt gave both parties a benefit — a debt that paid for a family holiday, a joint renovation, or joint living costs is more likely to be shared.
• Contributions during the relationship — financial and non-financial contributions (including unpaid caring work) are weighed by the court in the overall split.

A common practical approach in mediation is to assign each debt to the party who retains the asset it relates to (the mortgage stays with the home, the car loan with the car), and then adjust the overall split to ensure the outcome is equitable.

Protecting your credit while you negotiate

Property settlements in Australia can take months — and in contested cases, years. In the meantime, joint debts remain joint liabilities. Here are practical steps to protect yourself:

1. Get a copy of your credit report — check what accounts appear in your name and monitor for missed payments. Free credit reports are available from the major bureaus (Equifax, illion, Experian).
2. Contact lenders early — many lenders have hardship teams that can assist with temporary reduced repayments, interest-only periods, or repayment deferrals while a settlement is negotiated.
3. Document post-separation spending — keep records of who used which accounts after separation and for what. This evidence can be relevant if a credit card balance is disputed in the settlement.
4. Get interim orders if needed — the Federal Circuit and Family Court of Australia can make urgent interim orders to freeze assets, prevent additional debt being incurred in joint names, or require one party to maintain loan repayments pending final settlement.
5. Consider separate accounts — as soon as practicable, open individual accounts and redirect your income and regular expenses there. This limits future joint exposure.

Resolving debt disputes through mediation

Debt questions are well-suited to mediation. Unlike parenting disputes, where the children's welfare introduces an emotional dimension that can be hard to de-escalate, debt allocation is fundamentally a numbers problem — and numbers can be worked through methodically.

In a property settlement mediation, the mediator helps both parties:

• Prepare a full schedule of assets and liabilities (including all debts, not just the ones both parties agree about)
• Agree valuations — or a process for getting independent valuations
• Work through how debts should be allocated given contributions, capacity, and fairness
• Reach a written agreement that both parties can take to their solicitors to be formalised as consent orders

Reaching a mediated agreement on debts has one significant advantage over a court order: you can include provisions the court cannot order, such as timelines for refinancing, agreed communication with lenders, or interim repayment arrangements. These practical details often make the difference between an agreement that holds and one that unravels.

For couples where one party is concerned the other will not comply with an agreement, consent orders — approved by the FCFCOA consent orders — carry the same legal force as a court order and can be enforced if they are breached.
