If My Husband Owns A Business Do I Own It Too?

You watched him build it. All the early mornings before the profit poured back in, the many years it created stress for you long before it paid in money. It’s in his name, and he started it before you met. So when the marriage ends, is the business his to keep?

Here is the plain answer. In Australia, one national law applies. There is no “community property”, no state-by-state system, none of the United States framing you may have read online. The business is almost always counted in the property pool, whoever’s name is on it and whoever started it. A court can adjust who ends up with what under the Family Law Act, using s 79 for married couples and s 90SM for de facto couples.

I have watched this land on business owners more than once.

We had a client who owned a plumbing business. He started it before the marriage, it was in his name, it was his tools, his van, and he thought, sweet, this is all mine, she can’t touch this. But we had to tell him the news that he didn’t want to hear: it doesn’t matter who started it, if the business is there at the end of it, it’s part of the property pool.

Whether the business survives intact, and how the other side gets paid out, is where the real work happens. Let me walk you through it, the same way I would if you were sitting across from me.

How Australian law actually divides a business

Forget the idea that a court grabs a calculator and splits everything in half. It does not work that way. The division runs through a four-step process, and it is worth understanding because it tells you where a business fits.

1. Identify and value the pool. Everything both of you own and owe, the business included, goes into one pool.
2. Weigh the contributions. What each of you put in, financially and otherwise, over the life of the relationship.
3. Adjust for future needs. Age, health, earning capacity, care of children, and who walks away with more capacity to rebuild.
4. Check the result is just and equitable. The court steps back and asks whether the overall split is fair in the circumstances.

That last step is not a formality. A court cannot make an order adjusting property unless it is satisfied the order is just and equitable in the first place.

There is one recent change worth knowing. From 10 June 2025, when it works through those steps the court must also weigh the economic effect of any family violence in the relationship. That can shift how contributions and future needs are assessed.

Do I have a claim to my husband’s business after marriage?

The better question is not whether you have a “claim” to the business. It is what the business is worth to the pool, and what weight your contributions carry.

Those contributions are broader than most people expect. Direct financial input counts, money you put in, work you did in the business. So does the indirect and non-financial side: running the home, raising the children, holding everything else together so he could pour himself into the business. The law sees both as real contributions, because they are.

You might assume a business built before the relationship counts as his alone. It does not, and here is why. A pre-marriage or pre-relationship start does not shield a business from the pool. It goes in regardless. What the timing changes is the weight given to it, not whether it counts. A business he built for a decade before you met, and one you both built together, are weighed differently. But both sit in the pool.

How each business structure is treated

The structure the business sits in changes the detail, not the outcome. Here is the short version, before the part that catches people out.

• Sole trader. The business and the person are the same thing legally. It sits in the pool directly.
• Partnership. The share of the partnership is what comes into the pool, valued on its own.
• Company. The shares, and the value behind them, are counted.
• Discretionary trust. This is where a lot of people think they are protected. Often they are not.

Here is the tricky bit. People assume assets held in a discretionary trust sit safely outside the pool. That assumption gets tested hard.

I’ve had cases where a business was technically owned by a discretionary trust. The other side argued the trust assets were not to be included in the pool, but because the other side had day-to-day control of the business and was receiving funds from the business as if they were the business owner, the court decided they had effective control and the trust assets were included in the settlement.

Control and benefit are what the court looks at, not the label on the paperwork. If a party runs the business day to day and draws from it as if they own it, a court can find effective control and pull the trust assets into the pool. It can also unwind transactions set up to defeat a claim, moving assets, restructuring on the eve of separation, using the power in s 106B of the Family Law Act.

Reference: control and benefit test, Kennon v Spry [2008] HCA 56; power to set aside transactions that defeat a claim, Family Law Act 1975 (Cth), s 106B.

How is a business valued in a divorce in Australia?

Valuation is more disciplined than a back-of-the-envelope guess. In practice, the parties usually agree on a single expert, a forensic accountant, who is jointly instructed and values the business as at a set date. The goodwill, the value in the business beyond its hard assets, is treated separately from equipment, stock and cash.

There is a catch worth flagging. Valuation runs on the numbers the business puts forward, so the numbers get scrutinised.

The court will look at whether those debts are genuine business expenses or whether they’ve been artificially created to reduce the value of the business. This happens quite often. If they think you’ve taken on unnecessary debt to lower the payout, the court can adjust for that.

Both sides owe a duty of full and frank disclosure of the business’s finances. If the figures are dressed up, loaded with debt that is not genuine, income running through in ways that hide the real value, a court can adjust for it and can unwind transactions built to defeat a claim.

Reference: duty of full and frank disclosure; power to set aside transactions, Family Law Act 1975 (Cth), s 106B.

A real outcome

A business being in the pool does not mean it has to be sold. Most of the time the argument is about how the other side gets paid, not whether the doors stay open.

We worked with a client who owned a manufacturing company with high fixed costs, and the valuation came back at one and a half million dollars, but their liquid cash was tight. So what we did was negotiate a deal where the payout to the other spouse was split into three instalments over two years, and it was secured against their property.

The company kept running. The other spouse got a fair payout, structured so it did not force a fire sale. This lesson is the one I give every business owner who walks in convinced they are about to lose everything, that the business being counted is the start of the conversation, not the end of it. What you negotiate is how it gets paid.

Can a Binding Financial Agreement protect the business?

Yes, within limits. In Australia we do not use the term “prenup”. The legal instrument is a Binding Financial Agreement, or BFA. Same idea, different name.

A BFA can quarantine a business by setting out, in advance or during the relationship, that it stays with the owner and how it is treated if you separate. It gives certainty a court process cannot.

It is not bulletproof. A court can set a BFA aside in limited circumstances set by law, for example if it was signed under pressure, if there was no proper financial disclosure, or if it was affected by fraud or unconscionable conduct. Done properly, with independent advice on both sides, it is one of the strongest protections a business owner has.

Reference: Binding Financial Agreements, Family Law Act 1975 (Cth), s 90B (married) and s 90UB (de facto).

What a transfer costs in tax

When a business asset moves from one spouse to the other as part of a settlement, capital gains tax usually does not bite at that moment. The relationship-breakdown rollover means the transferring spouse generally pays no CGT on the transfer. The receiving spouse inherits the original cost base and pays the tax later, when they eventually sell.

One condition matters. The rollover only applies where the transfer happens under a court order, a consent order or a BFA. An informal handshake does not qualify, and getting this wrong can hand one spouse a tax bill they never saw coming.

Reference: ATO, relationship breakdown and capital gains tax.

Can business assets be considered personal in a divorce?

Australian family law has no “separate property” category. A business held in one name, or built before the relationship started, is still in the pool. What changes is the weight given to the contributions behind it, not whether it counts at all. The sooner you understand that, the sooner you can stop worrying about the wrong question and start working on the one that matters: how the pool is divided.

I’ve seen business owners come out of divorce with their business intact and thriving, and I’ve seen others lose control of something they spent years building. The difference almost always comes down to preparation, strategy and understanding the legal process.
