Using property for the business after a separation: should you, and when?

Separation rarely arrives at a convenient time for a business. Cash gets tight just when legal fees start, the person who did the books may have moved out, and the property that once felt like a safety net is suddenly up for negotiation. It’s natural to look at the equity and wonder whether it can steady the business.

Sometimes it can. But the order in which you do things matters more here than almost anywhere else, and the honest answer is often “yes, but not yet”.

Why does timing matter so much after a separation?

Until a property settlement is final, the property and the business are usually both part of the shared property pool. That’s true whether the title is in joint names or yours alone. Borrowing against an asset whose ownership is still being worked out creates problems in three directions:

• With your former partner. If they’re on title, they must agree and sign. Even if they aren’t, a new debt against a shared asset tends to sour negotiations quickly.
• With your settlement. A new loan changes the numbers both sides are arguing over. Your family lawyer will want to know about it before it happens, not after.
• With lenders. Most lenders will want to understand where the separation is up to and who will own the property when it’s done. An unresolved settlement is one of the most common reasons a sensible application stalls.

Federal Circuit and Family Court of Australia guidance says married couples generally need to apply for property orders within 12 months of a divorce becoming final, and de facto couples within two years of the relationship ending. Many people formalise their split well before those deadlines, through consent orders or a binding financial agreement. That formal step is usually the point where a business second mortgage becomes a real option rather than a complication.

What changed in family law in 2025?

The court notes that from 10 June 2025 the Family Law Act sets out more clearly how property settlements are decided and what’s taken into account. It also says the changes apply to couples sorting things out themselves, not only those in court.

You don’t need to master the detail; your lawyer will. The practical point for a business owner is simpler: the settlement framework is the thing that decides who ends up with which property, so let it finish before you put a new loan against any of them.

Is there a time it makes sense to borrow before settlement?

Rarely, and only with both of you, and both lawyers, on the same page. An example is a business both former partners still own, with a tax debt or a supplier crisis that’s eroding its value for everyone. A short, agreed loan that protects the asset can be in both parties’ interest. Even then, the decision belongs in the settlement conversation, documented, and not made at the kitchen table at midnight.

If the business can be kept afloat for a few months with a payment plan, supplier terms or an unsecured option, that’s usually a calmer bridge to the settlement than a second mortgage.

After settlement: what’s different about the decision?

Once the property is yours, the usual decision-first questions apply. See should I use my house? for the full version. But post-separation, a few answers tend to look different:

Before the separation	After the separation
Two incomes carried the home loan	One income does, plus any child support or maintenance
A healthy equity cushion	The home loan may have grown to pay out your former partner
A partner who could step in at the business	You may be running everything alone
A shared fallback plan	Your fallback is now yours alone to fund
The home was “ours”	The home may be where your children live half the week

None of this rules a second mortgage out. It does mean the amount you can carry comfortably is often lower than the equity figure suggests, and the bar for a clear exit is higher.

If your settlement is done and you’d like a specialist to look at whether the numbers stack up, you can send a short enquiry. There’s no credit check when you first enquire.

Which property should carry the loan?

Settlements often leave one person with the home and the other with an investment property, a holiday house or business premises. If you have a choice, choosing the property walks through the general trade-offs. Two post-separation points are worth adding.

Protecting the children’s home. If children live in the home, even part of the time, keeping it out of a business loan is often worth a slightly worse arrangement elsewhere. See protecting the family home.

The inherited cost base. The ATO explains that when an asset is transferred under a court order or a formal agreement because of a relationship breakdown, a capital gains tax rollover can apply. The person who receives the asset effectively takes over the original owner’s cost base. In plain terms: if you received an investment property your former partner bought fifteen years ago, a future sale may carry a capital gain built up over all fifteen years, not just the time you’ve owned it.

That matters if “sell the investment property” is your exit. The cash left after tax could be noticeably less than the sale price suggests. Ask your accountant to estimate it before you count on it.

What business purposes make sense after a separation?

Some purposes fit this stage of life well. Others are a warning sign.

Purpose	How it usually reads
Buying out your former partner’s share of the business	Often sensible if valued properly and structured with advice. See partner buyout
Rebuilding working capital the business lost funding the settlement	Can be sensible with a cash-flow exit you’ve tested
Clearing an ATO debt that built up during the separation	Often sensible, especially with ATO interest no longer deductible
Replacing the income your former partner brought to the household	Not a business purpose, and not a good use of property equity
Covering ongoing losses “until things settle down”	A red flag. Fix the trading problem first

The common thread: the money should make the business stronger in a way you can measure, with a clear repayment path. It shouldn’t paper over the gap a separation leaves at home.

An illustrative example

A café owner in her forties finalises a property settlement through consent orders. She keeps the house, worth $900,000, and refinances the home loan to $520,000 to pay out her former partner, a combined LVR of about 58%. Her former partner’s share of the café was bought out in the same settlement, but doing so drained the café’s cash reserve and left an ATO debt of $70,000.

She considers a $150,000 second mortgage to clear the tax debt and rebuild working capital. That would take the combined LVR to about 74%. On a valuation 10% lower, it’s about 83%, with one income and two children at home half the week.

Running the numbers through the equity decision helper and a stress test, she scales back. She borrows $90,000 against the home (combined LVR about 68%) to clear the tax debt and give the café a three-month buffer, and leaves the rest to a small unsecured line sized on the café’s turnover. Her exit is twelve months of improved trading, with a checkpoint at month six. Illustrative only; no rates or repayments shown.

What questions should you answer honestly first?

• Is the settlement final and formalised? If not, talk to your lawyer before anyone else.
• Can one income carry the home loan and the business through a bad quarter?
• Who would run the business if you were unwell for a month? After separation, the honest answer is sometimes “nobody”.
• Are you deciding calmly? Separations come with urgency and exhaustion. If a decision can wait four weeks without real harm, let it.
• Would you still make this choice if you weren’t trying to prove the business can survive without your former partner? It’s a fair question to ask yourself.

Your accountant is often the best sounding board, because they can see the business, the settlement and the tax side together.

Starting again, with your eyes open

Rebuilding a business after a separation takes courage, and sometimes it takes capital too. If the settlement is final and the purpose is clear, we’re happy to look at whether property equity is the right tool, or whether something lighter would do the job.

The enquiry takes about a minute and there’s no credit check when you first enquire. We don’t send your details to a pile of lenders. It goes to one specialist, so your phone won’t start ringing off the hook. A real person will read your situation and call you, and if a second mortgage isn’t the sensible move, they’ll say so. Please fill the form in accurately, including who is on the title now, what’s owed, the amount you need and how you plan to repay it, so the first conversation is a useful one.
