Key takeaway: A business is treated as property in a divorce and forms part of the asset pool. It must be valued (often by an expert), and the value is then factored into the overall division — usually by one party retaining the business and offsetting its value against other assets, rather than splitting the business itself. Companies and trusts add complexity. Mediation is well suited to keeping a business intact.
Is a business part of the property pool?
Yes. Under the Family Law Act 1975, a business — whether a sole trader operation, a company, or an interest in a partnership — forms part of the asset pool to be divided, just like the family home or superannuation. This is true even if only one partner runs it, and even if it was started before the relationship (though the timing and contributions affect how it's treated). See how the asset pool works →
The contributions of a non-business-owning partner are also recognised. If one partner ran the household and cared for children while the other built the business, those homemaking contributions are counted. The family law framework looks at the whole picture of contributions, not just whose name is on the ABN.

Valuing a business is rarely as simple as looking at its bank balance. Depending on the business, valuation may consider net assets, future earning capacity, goodwill, and comparable sales. For anything beyond the simplest operation, an independent expert valuation is usually needed (the Federal Circuit and Family Court of Australia deals with complex business valuations regularly) — and the parties may need to agree on a single expert to avoid duelling valuations that add cost and delay. Getting the value right matters enormously, because it drives the whole settlement.
The timing of valuation matters too. A business valued at peak earnings will look different from one valued during a downturn or while the owners are in dispute. An expert valuer who understands family law methodology (not just commercial practice) is worth engaging early.
Valuation methods compared
| Method | Best suited to | Key consideration |
|---|---|---|
| Capitalisation of earnings | Profitable ongoing businesses | What multiple of maintainable earnings? |
| Net assets (balance sheet) | Asset-heavy businesses, holding companies | Goodwill may be understated |
| Discounted cash flow | Growth businesses with forecast revenue | Sensitive to assumptions; often contested |
| Comparable market sales | Businesses in active sale markets | Requires good comparable data |
| Market value of shares | Minority interests in private companies | Discount for lack of control/marketability |
In practice, the parties often agree on a single expert valuer to avoid costly competing reports. Where they can't agree on value, the mediator can help structure a process — such as each party nominating an expert and splitting the difference, or jointly engaging a third expert.
How is a business divided?
Contrary to what many fear, the business itself usually isn't carved up or sold. The far more common outcome is that one partner retains the business and its value is offset against other assets — for example, the business-owning partner keeps the company while the other receives a larger share of the home or superannuation. This keeps the business intact and operating. Where that's not possible, options include a payout over time or, as a last resort, sale.
Creative structures are also possible through mediation that a court might not readily impose: a staged buyout over several years, a short-term joint operation with an agreed exit, or a licensing arrangement where the non-business partner retains a revenue interest for a period. These work best when both parties have a shared interest in the business surviving the separation period.
Companies and trusts
Where assets are held in a company or family trust, things get more complex — but they're not out of reach. The court can look behind these structures to determine who really controls and benefits from the assets, and can treat them as part of the pool or as a financial resource. Structures set up to shield assets from a settlement rarely work as intended. See the duty of disclosure →
Family discretionary trusts are a particular area of complexity. Technically, the assets belong to the trust and neither party "owns" them. In practice, courts and mediators look at who the real controller and beneficiary is. If one partner effectively controls and benefits from the trust, those assets are likely to be treated as a financial resource or brought into the pool. Getting specialist advice on trust structures early in a property settlement is strongly recommended.
How to protect your business
- A binding financial agreement — a BFA (prenup or during the relationship) can quarantine a business from a future settlement. This only works if done properly with independent legal advice for both parties.
- Clear records — keep business and personal finances separate and well documented. Mixing personal expenses through the business creates confusion about the real value and your contributions.
- Realistic valuation — engage early with a credible independent expert rather than relying on informal estimates. An accurate valuation protects you whether the outcome ends up favouring you or not.
- Mediate, don't litigate — a court fight can damage the very business you're trying to protect. Uncertainty, management distraction, and the risk of a forced sale are all real litigation costs beyond legal fees.

One of the less-discussed challenges is keeping the business running while a settlement is being negotiated. Long litigation creates real business risk: key decisions may stall, staff and clients can sense instability, and the value you're fighting over may actually decline during the process. This is another reason why reaching agreement quickly matters for business owners — not just to resolve the legal dispute, but to protect the underlying asset.
Where both parties have roles in the business, a temporary operating agreement — covering how decisions will be made, how profits will be dealt with, and what each party's role is during the settlement period — can prevent the business from becoming a casualty of the separation. A skilled mediator can help structure this. See our property mediation service →
Why mediation suits business matters
Business-related settlements are exactly where mediation shines. It's confidential — so sensitive financial details stay private rather than entering the public court record. It's faster — so the business isn't left in limbo for years. And it's flexible — letting you craft creative solutions (offsets, staged payouts, ongoing arrangements) that a court might not order. For business owners, mediation is almost always the smarter path. Compare mediation and court →
A mediator experienced in business matters can also help parties reality-test their positions against what a court would actually be likely to do — grounding the negotiation in realistic outcomes rather than hopeful ones. That practical anchor often helps both sides move toward agreement more efficiently than a lengthy legal battle that ends at a court's discretion anyway.
