What happens to the mortgage
when you separate in Australia?

When a relationship ends, the family home is often the first and most complex financial question that comes up. What happens to the mortgage? Who keeps paying it? What are your options? And what happens if your ex stops making repayments?

These are questions we hear constantly at Lendology from people navigating separation in Adelaide and across South Australia. The answers are not always straightforward — but they are knowable. Here is a clear, honest guide to what happens to your mortgage when you separate in Australia.

Both of you remain liable — until the loan is formally resolved

This is the most important thing to understand: separation does not change who is legally responsible for a joint mortgage. Until the loan is formally refinanced into one person's name, or the property is sold and the loan discharged, both parties remain jointly and severally liable.

This means the lender can pursue either of you for the full amount of the debt — regardless of any private agreement you have made between yourselves. A separation agreement that says "you pay the mortgage and I'll pay rent elsewhere" has no legal standing with the lender. In their view, you are both equally responsible for every repayment.

This applies even if one person has moved out of the property entirely.

What joint liability means in practice

Both credit files are affected

If the mortgage falls into arrears — even by one payment — it will appear as a default on both credit files. It does not matter who was supposed to be paying. Lenders report to credit bureaus based on the loan account, not based on who was responsible under a private arrangement.

This is one of the most significant risks during separation, particularly if communication has broken down and you are not certain the repayments are being made.

The mortgage counts as your debt

While the joint mortgage remains in both names, it counts as a liability for each of you individually. This means if either party tries to borrow money — say, to rent a new property or purchase somewhere else — the full mortgage repayment will be assessed as your commitment, regardless of the arrangement with your former partner.

This effectively limits both parties' ability to move on financially until the mortgage is resolved.

You cannot simply remove your name

It is a common misconception that one party can simply "sign off" the mortgage. This is not how it works. Removing a name from a joint mortgage requires a formal refinance — the remaining borrower must apply to a lender as a sole applicant, demonstrate they can service the debt independently, and go through a full credit assessment. The existing loan is essentially replaced with a new one.

Your three main options

Option 1: One person keeps the home and refinances

If one party wants to stay in the property, they need to refinance the existing joint loan into their name alone — and typically buy out the other party's equity share at the same time. This is called a partner buyout.

The new loan covers the existing loan balance plus the agreed equity payout, plus any legal and transfer costs. The remaining party must demonstrate they can service this new, larger loan on their individual income.

Whether this is achievable depends on income, the size of the loan, and current lender policies. A mortgage broker can give you a realistic picture of whether it is possible before you commit to anything in your legal negotiations.

Option 2: Sell the property

Selling the property is often the cleanest resolution. The sale proceeds are used to repay the mortgage, selling costs are deducted, and the remaining net proceeds are split according to the agreed ownership entitlement.

Both parties then walk away from the mortgage entirely, freeing each of them to assess their individual borrowing position for whatever comes next.

Option 3: Wait — but understand the risks

Some couples choose to maintain the current position while legal proceedings continue. This can make sense in some circumstances — particularly where property values are expected to rise, or where the legal process is close to resolution.

However, waiting carries real risks. Both parties remain jointly liable. The mortgage continues to affect both credit files. And the outstanding debt continues to limit both parties' ability to move forward financially.

What needs to happen legally

Property settlements in Australia must be formalised through one of two legal mechanisms:

• Consent Orders — filed with the Family Court of Australia. Both parties agree to the terms and the court makes orders recording that agreement. Once made, Consent Orders are binding and enforceable.
• Binding Financial Agreement (BFA) — a private contract between the parties, prepared with independent legal advice on both sides. BFAs do not go through the court but are legally binding if properly prepared.

It is important to understand that you generally have 12 months from the date of divorce (or two years from separation for de facto couples) to apply for a property settlement through the courts. Missing this window can significantly limit your options.

Your family law solicitor manages this process. Your mortgage broker's role is to ensure the finance side aligns with whatever the legal agreement requires — whether that means refinancing within a particular timeframe, or structuring a new loan to match the settlement terms.

What to do first

The right order of steps is important. Many people make the mistake of trying to sort out the finance before the legal position is clear, or conversely, signing a legal agreement before understanding whether the finance side is actually achievable.

Here is the order we recommend:

1. Get independent legal advice first — understand your rights and the likely settlement range before negotiating.
2. Speak with a mortgage broker early — before you agree to keep the home, understand whether you can actually afford to. A broker can give you an indicative borrowing assessment at no cost.
3. Keep making repayments — until the mortgage is formally resolved, both parties should ensure repayments are maintained to protect both credit files.
4. Do not act unilaterally on the property — do not attempt to sell, rent, or make major decisions about the property without legal advice and agreement from both parties.
5. Formalise the agreement — once both parties have agreed, formalise through Consent Orders or a BFA before proceeding with any finance changes.

How a mortgage broker helps during separation

A mortgage broker who understands separation finance can add significant value at several points in the process:

• Before negotiations: Providing an indicative borrowing assessment so you know whether keeping the home is actually achievable before agreeing to it.
• During settlement: Identifying which lenders will proceed with a refinance based on your specific circumstances — including income type, existing debts, and the legal documentation available.
• At settlement: Managing the refinance or discharge process in coordination with your solicitor and conveyancer to ensure the finance and legal steps align.
• After settlement: Helping you assess your position for any new purchase, whether that is right away or further down the track.
