How Are Debts Divided in Divorce? Australian Property Settlement Explained

When people separate, one of the most common questions is also one of the most misunderstood: what happens to the debts?

Many people assume there must be a simple rule. Half each. Joint debts are shared. Personal debts stay personal. In Australian family law, it is not that straightforward.

In a property settlement, debts are part of the broader financial picture. The court does not simply ask whose name a debt is in. It looks more carefully at what the debt is, why it was incurred, whether it benefited the relationship, and whether it should properly be taken into account at all.

That distinction matters. It can make a significant difference to the final outcome of a property settlement.

The starting point: working out “the pool”

One of the first steps in any Australian property settlement is to identify the property pool. That means working out the assets, superannuation and liabilities that need to be considered before any division can occur.

In simple terms, the pool is the net financial position of the parties.

That requires a proper analysis of:

• Assets, such as the family home, savings, cars and investments
• Superannuation
• Liabilities, including mortgages, credit cards, tax debts and other loans

As a general rule, debts are often brought into the pool by deducting them from the value of the assets. But that is only the starting point. There are important exceptions, and debts are not all treated equally.

There is no automatic 50/50 rule for debts

This is one of the biggest misconceptions in family law.

There is no rule that says if a debt was incurred during the relationship, each person must pay half. There is also no rule that says every debt, whether joint or individual, must be included in the pool.

Instead, the court takes a more nuanced approach.

That means a debt might:

• be included in the pool and effectively shared as part of the overall property settlement
• be allocated to one party only
• be paid out from available assets
• be excluded altogether

So the real question is not simply, “Whose name is on the debt?” The real question is, how should this debt be treated for family law purposes?

Joint debts are usually included, but that is not the end of the story

Where a debt is in joint names, it will normally be included as a liability in the property pool. Common examples include:

• the mortgage
• a joint credit card
• a personal loan taken out together

These debts are commonly deducted from the assets when calculating the pool available for distribution.

However, family law treatment of debt is not the same as commercial treatment of debt.

That distinction is critical. A court may decide, as between the separating parties, that one person should bear responsibility for a particular joint debt. But that does not automatically bind the lender.

For example, if both parties are liable to a bank under a loan agreement, the bank will usually still be entitled to pursue either of them unless there is a specific order that affects that liability. In other words, a family law order may determine who should carry the debt between the parties, but it does not necessarily remove the creditor’s rights.

That is why debt issues often need both legal and practical consideration. A court allocation and a lender’s legal rights are not always the same thing.

Individual debts require closer analysis

Debts in one party’s sole name are usually where things become more complicated.

The court tends to look more closely at these debts and ask questions such as:

• What was the debt used for?
• Was it incurred for a joint purpose?
• Did it benefit both parties or the family?
• Was it reasonably incurred?
• Is it a genuine liability that is likely to be enforced?

If the debt was incurred for ordinary family purposes, it is more likely to be included in the pool. If it was incurred for something personal, excessive or wasteful, it may be treated very differently.

Debts that are often included

Examples of debts likely to be included in the property settlement calculation include:

• Mortgages
• Reasonable living expenses
• Joint credit cards
• Credit cards in one name that were used by both parties
• Tax debts incurred for joint purposes

If a debt arose as part of the couple’s ordinary financial life, or from the accumulation of wealth during the relationship, it is more likely to be regarded as part of the pool.

Debts that may be excluded

Other debts may be left out altogether, or treated as the sole responsibility of the person who incurred them.

Examples include:

• Gambling debts
• Unreasonable or excessive personal spending
• Wasteful expenditure, including some spending on alcohol or similar conduct
• Legal fees
• Post-separation debts incurred without the other party’s knowledge in some circumstances

The key idea here is fairness. If a debt did not benefit the relationship, or was incurred irresponsibly, the court may decide it should not reduce the pool available to both parties.

What counts as “waste”?

“Waste” is an important concept in family law property settlements.

It generally refers to one party dissipating assets or incurring liabilities in a way that is excessive, reckless or unrelated to the parties’ joint financial interests. Gambling is the clearest example, but it is not the only one.

If one party has run up debts through behaviour the court considers wasteful, those liabilities may be excluded from the pool or effectively assigned to that person alone.

This can have a major impact on the outcome. A debt that is excluded is not simply subtracted from the asset pool and shared by both parties. Instead, the person responsible may carry the burden personally.

What about legal fees?

Legal fees are usually treated differently from other debts.

As a general rule, each person is expected to pay their own legal costs. For that reason, legal fees usually do not go into the pool when calculating the assets and liabilities of the parties.

That is a point many separating couples do not expect. A person cannot usually assume that their legal bill will simply become a shared debt of the relationship for property settlement purposes.

Family loans and vague debts may not be accepted

Not every alleged debt will be recognised by the court.

Sometimes a party says they owe money to a parent, sibling or other family member. Sometimes there is a supposed liability that is poorly documented, uncertain in amount, or unlikely ever to be repaid.

In those situations, the court may disregard the debt.

Examples of debts that may be excluded include:

• a loan from family members that is unlikely to be enforced
• a debt that is vague or uncertain
• a liability that appears unlikely to be recovered

The court is concerned with real financial liabilities, not merely amounts that are asserted without proper substance.

How tax debts are treated

Tax debts can be significant, and they are often a major issue in property settlements.

Generally, tax liabilities will be included in the pool if they were incurred for joint purposes. For example, if the debt arose through income, business activity or wealth accumulation during the relationship, it will often be treated as part of the overall financial landscape.

But tax debts are not automatic inclusions.

There may be cases where a tax debt is incurred after separation and without the knowledge of the other party. In that situation, the court may determine that only one person should bear responsibility for it.

Once again, context matters. The court looks at how and when the debt arose, and whether it is fair for both parties to carry it.

Can debts be allocated to one party only?

Yes. In appropriate cases, the court can make orders that effectively allocate a debt to one party.

That might happen where:

• the debt was incurred solely for one person’s benefit
• the debt arose from post-separation conduct
• the spending was unreasonable or wasteful
• it would otherwise be unjust for both parties to share the burden

That said, it is important to remember the distinction between allocation between the parties and liability to a creditor. A court may order that one person should pay the debt, but unless steps are taken that affect the creditor’s rights, the lender may still pursue anyone who remains legally liable under the original loan or credit contract.

What if the debts are greater than the assets?

Sometimes there is what family lawyers call a negative pool. That means the liabilities exceed the assets.

Even in that situation, the court can still make orders about how debts should be dealt with between the parties.

A negative pool does not mean there is nothing to resolve. It simply means the focus shifts from dividing net assets to determining responsibility for net liabilities.

That can be especially important where there are mortgages, tax liabilities, unsecured loans or credit card debts that significantly outweigh the available property.

The practical takeaway

When debts are considered in an Australian property settlement, there is no single formula that applies in every case.

The practical effect is that a debt may be:

• included in the pool
• excluded from the pool
• assigned to one party
• paid from available assets

The outcome depends on the nature of the debt, the purpose for which it was incurred, the timing, the benefit to the relationship, and whether the liability is genuine and enforceable.

That is why debt issues should never be treated as an afterthought in a divorce or separation. The way liabilities are characterised can materially change the size of the property pool and the fairness of the final division.

Why early advice matters

Debts can be one of the most misunderstood parts of a property settlement. People often focus on assets and forget that liabilities may be just as important, particularly where credit cards, tax debts, personal loans or post-separation spending are involved.

Getting clear advice early can help identify:

• which debts are likely to be included
• which liabilities may be challenged
• whether a debt should be treated as personal to one party
• what risks remain with banks and other creditors
• how the overall property pool may be affected

In the end, debt division in divorce is not really about mechanically splitting liabilities down the middle. It is about properly analysing the financial history of the relationship and reaching a result that is legally sound and just in the circumstances.
