Separation is one of the most financially complex events a person can go through. Alongside the emotional weight, there are immediate and practical decisions to make about property, debt, and housing — often under significant time pressure. If you have a mortgage — either jointly or individually — understanding how banks and lenders treat separation can help you make clearer decisions and avoid costly mistakes.
This guide covers the key situations most people face: what happens to the existing home loan, how property is typically divided, what you'll need from a legal perspective before a bank will act, and what to consider if you need to buy a new property on your own.
This applies to both marriages and de facto relationships.
Under Australian family law, de facto couples who have been together for at least two years (or have a child together, or where one partner made significant contributions) have essentially the same property rights as married couples. The same principles around property settlement, court orders, and binding financial agreements apply.
The key difference is timing: married couples must commence property settlement proceedings within 12 months of divorce being finalised, while de facto couples have 2 years from the date of separation.
What typically happens with property
When a couple separates, there are generally three paths for the family home:
One partner buys out the other and keeps the home
One person refinances the joint mortgage in their name only, releases the departing partner from the loan, and pays them their share of the equity. This is the most common outcome when children are involved or when one partner has strong emotional ties to the property. It requires the remaining partner to qualify for the loan on their own income.
The property is sold and proceeds are divided
Both parties agree to sell the home, the existing mortgage is discharged from the sale proceeds, and the remaining equity is split according to the agreed or court-ordered settlement. This is often the cleanest path financially, though it means both parties need to find new housing simultaneously — and sale costs (agent fees, CGT where applicable) reduce the net proceeds.
Both parties continue to co-own (temporarily)
In some cases — particularly where one partner is not immediately in a position to buy out the other, or where the parties wish to wait until children finish school — the property is held jointly for a defined period before being sold or transferred. This is a legally complex arrangement that requires careful documentation. Both parties remain jointly liable for the mortgage during this period.
Separation does not automatically change your mortgage. Until the loan is formally refinanced, transferred, or discharged, both parties remain jointly and severally liable for the debt. This means if one partner stops making repayments, the other is fully responsible — and both credit files are affected. Notify your lender early and get legal documentation in place as quickly as possible.
What banks need before they'll act
Banks won't simply take one partner's name off a mortgage, release equity to one party, or approve a transfer of ownership based on verbal or informal agreements. They require formal legal documentation before any changes are made to the loan structure. There are two main types of documents that satisfy this requirement.
Court orders (Consent Orders)
Orders made by the Family Court — either by agreement (Consent Orders) or after contested proceedings — that formalise how property is to be divided.
- Issued by the Federal Circuit and Family Court of Australia
- Can be Consent Orders (agreed by both parties and approved by the court)
- Binding and enforceable — banks accept these without question
- Provide stamp duty exemptions in most states when transferring property between separating parties
- Can be obtained without going to a full hearing — most are Consent Orders
- Typically takes 8–12 weeks to obtain once both parties agree
Binding Financial Agreement (BFA)
A private contract between the parties that sets out how assets and liabilities are divided, without needing court approval.
- Both parties must have independent legal advice before signing
- Can be made before, during, or after a relationship
- Faster and potentially cheaper than Consent Orders
- Stamp duty exemptions may still apply — varies by state
- Less scrutinised than Consent Orders — can be challenged in some circumstances
- Banks will accept a BFA but some lenders require it to be certified correctly
Which one does a bank prefer? Most lenders will accept either a registered Consent Order or a properly executed Binding Financial Agreement as evidence of how property is to be dealt with. Consent Orders are generally considered more robust and are the preferred document for stamp duty exemption purposes. Your solicitor or family lawyer can advise which suits your situation.
Important: The stamp duty exemption on property transfers between separating parties is one of the most significant cost savings available — but it only applies when the transfer is made pursuant to a family law order or agreement. Don't transfer property informally without this documentation in place.
Refinancing the marital home — paying out a partner's equity
If one partner is keeping the home, the process involves three things happening simultaneously: removing the departing partner from the mortgage, adding (or retaining) the remaining partner as sole borrower, and paying out the departing partner's share of the equity in cash.
❌ Joint loan — before settlement
✓ Solo loan — after settlement (50/50 split)
In this scenario, the remaining partner (Partner A) refinances the $550,000 loan into their name only and borrows an additional $175,000 to pay out Partner B's equity share — resulting in a new solo loan of $725,000. The new loan is assessed entirely on Partner A's income and financial position. Lenders assess this as a standard refinance.
Key steps in the refinance process:
1. Get a valuation. The bank will require an independent property valuation to determine current market value before approving the refinance. This is arranged by the lender and forms the basis for calculating equity available.
2. Assess serviceability solo. The lender assesses whether the remaining partner can service the new (higher) loan on their income alone. This is the most common sticking point — what two incomes could easily service may be a stretch for one.
3. Provide the legal agreement. The Consent Order or BFA must be provided to the lender before settlement. This tells the bank exactly how much equity is owed to the departing partner and authorises the transaction.
4. Settle simultaneously. The refinance, the equity payout, and the title transfer all happen on the same settlement day, coordinated by the solicitors on both sides.
Property valuations — what you need to know
A fair property value is the foundation of any settlement. Getting the valuation right — and understanding how lenders approach it — prevents disputes and ensures neither party is disadvantaged.
Bank valuation (for refinance)
When you refinance, the lender orders a valuation through their approved panel valuers. This is a formal assessment that determines how much they'll lend against the property. Bank valuations are often conservative — they typically value at the lower end of the market range to manage their own risk. This figure drives the loan approval and the LVR calculation.
Independent market valuation (for settlement)
For the purposes of negotiating the property settlement itself, either party (or both jointly) can engage a registered property valuer to provide an independent market appraisal. This is different from the bank valuation and is used to determine what the property is actually worth in the current market. If the parties disagree on value, each may obtain their own valuation and negotiate from there.
Real estate agent appraisal
An agent's appraisal is not a formal valuation and should not be used as the basis for a legal settlement. Agents may appraise optimistically to win a listing. While useful for a ballpark figure, any formal settlement or refinance must use a registered valuer's report.
Disagreements over valuation are common. If both parties obtain independent valuations that differ significantly, the courts can appoint a single joint expert valuer whose assessment is binding. Your family lawyer can advise on this process. In general, a jointly agreed valuation at the outset avoids significant time and legal costs later.
Buying a new home after separation
If you're the partner leaving the family home, or if the property is being sold and you need to buy independently, there are specific challenges and considerations to work through before approaching a lender.
✓ What works in your favour
- Equity payout from the family home can form a strong deposit
- Single income may be supplemented by child support or spousal maintenance (most lenders will shade these to 80% of the amount, but they count)
- First home buyer concessions may be available again in some states if you were not the registered owner of the previous property
- Stamp duty exemptions under family law can free up cash that would otherwise be spent on transfer costs
- Some lenders offer separated parent policies — worth asking your broker
✗ What creates challenges
- Single income servicing — the same property at the same price now requires one income to qualify
- Joint debts not yet discharged may appear on your credit file and affect borrowing capacity
- If settlement is unresolved, some lenders are reluctant to approve until the financial position is clear
- Time pressure — needing to buy quickly while also navigating legal proceedings
- Guarantor options are more limited as a solo borrower
- Reduced savings buffer after separation costs, legal fees, and relocation expenses
Speak to a broker before you start looking. Getting a pre-approval or borrowing capacity assessment early tells you exactly what you can borrow in your new situation — before you fall in love with a property you can't finance. A broker can also identify which lenders have the most favourable policies for separated borrowers, particularly around child support income and existing joint liabilities.
Documentation checklist for lenders
Lenders assessing a separated borrower — whether for a refinance or a new purchase — will typically require additional documentation beyond the standard application. Being organised here saves time and avoids delays.
Legal settlement documents
- Consent Orders or Binding Financial Agreement (signed and registered)
- Separation agreement if Consent Orders not yet finalised
- Divorce certificate (if applicable and relevant to timeline)
- Title transfer documents (if property is being transferred)
Income documentation
- Last 2 payslips (if employed)
- Last 2 years tax returns (if self-employed)
- Child support assessment letter (from Services Australia)
- Evidence of child support payments received (last 3–6 months bank statements)
- Spousal maintenance agreement or court order if receiving maintenance
Property documents
- Current mortgage statement (existing loan)
- Property valuation report (if refinancing)
- Contract of sale (if new purchase)
- Rates notice (current financial year)
- Building and pest inspection reports (for purchase)
Liability and asset documents
- Bank statements (last 3 months — all accounts)
- Statement of any joint debts being retained or discharged
- Superannuation statement (may be relevant to settlement equity)
- Written confirmation of equity payout amount expected
- Evidence of deposit funds (if savings or equity payout)
How different scenarios compare
| Scenario | What lenders need | Key consideration |
|---|---|---|
| Refinance — keeping home solo | Consent Orders or BFA, valuation, solo serviceability | Can you qualify on one income? Assess this first |
| Buying a new property separately | Settlement confirmation, income docs, equity payout as deposit evidence | Settlement must be near-finalised before bank lends against it |
| Joint property being sold | Sale contract, both parties to discharge mortgage at settlement | Both parties must cooperate — disputes delay everything |
| Continuing joint ownership (temporary) | Written agreement between parties on ongoing responsibilities | Joint liability continues — both credit files at risk if payments miss |
| No legal agreement yet (informal separation) | Most lenders will not act until documentation is in place | Get legal advice and documentation before approaching lenders |
| Receiving child support / maintenance | CSA assessment letter, 3–6 months payment history | Most lenders shade to 80% of the stated amount for serviceability |
The bottom line
Separation creates genuine complexity in the mortgage world — but it's navigable with the right sequence of steps. The most important things are to get formal legal documentation in place early, not to make informal transfers or repayment changes before that documentation exists, and to work with a mortgage broker who has experience with separated borrowers. The earlier you understand your borrowing position, the more clearly you can make decisions about housing.
The steps in order of priority:
1. Get legal advice immediately. A family lawyer can guide you on Consent Orders versus a BFA, protect your interests in the settlement, and produce the documentation banks require. Don't approach a lender before this is underway.
2. Notify your lender about the separation. They can note the account, explain your options, and flag any actions needed to protect both parties while the settlement is pending.
3. Get a property valuation. Agree on a single joint valuation with your former partner if possible. This becomes the basis for the equity split and the refinance amount.
4. Speak to a broker about your borrowing capacity. Understanding what you can borrow on your own income — before settlement is finalised — helps you plan housing decisions more clearly.
5. Don't miss repayments on the joint loan. Regardless of who is living in the property or what informal arrangements exist, missed payments affect both credit files. Maintain repayments until the loan is formally restructured.
