Business Valuation in Family Law

When a couple separates and one or both parties hold interests in a business, that business must be valued as part of the property settlement. Business valuations are among the most complex and contested aspects of family law property proceedings — understanding the process helps you engage meaningfully with it.

When business valuations are needed

A business valuation is required whenever a party to a property settlement holds an interest in a business that has more than trivial value. This applies to sole traders, partnerships, companies, and interests held through trusts.

Types of business interest

Sole trader. The simplest business structure, where one person operates the business in their own name. The business assets, liabilities, and goodwill are all owned by that individual. Valuation focuses on the maintainable earnings and any transferable goodwill.

Partnership. Where two or more people carry on business together, the party's share of the partnership interest is valued — taking into account the partnership agreement, profit-sharing arrangements, and the value of the partner's individual interest, which may be subject to minority discounts.

Company. A separate legal entity with shareholders and directors. The party's shareholding is valued based on the underlying value of the company. Where the party holds a controlling interest, the full proportionate value is usually adopted. Minority shareholdings may attract discounts.

Trust. Businesses operated through discretionary or unit trusts require careful analysis. The court examines who controls the trust (appointor, trustee) and who benefits from it. Trust interests may be treated as property or financial resources depending on the degree of control.

Date of valuation

The court generally requires the business to be valued as close to the date of the final hearing as possible. This reflects the principle that the asset pool should be assessed at its current value. The valuer's report will typically be based on the most recent financial year's accounts, with adjustments for any material changes since the reporting date.

Valuation methods

There are three primary approaches to business valuation. A qualified valuer will select the method — or combination of methods — most appropriate for the particular business.

Income approach

Values the business based on its ability to generate income. This is the most commonly used method for profitable, established businesses.

Capitalisation of Future Maintainable Earnings (CFME) — the most common method. Future maintainable earnings (FME) are estimated by analysing historical earnings and normalising them to remove one-off items and personal expenses. The FME is then multiplied by a capitalisation factor to arrive at a business value.
Discounted Cash Flow (DCF) — projects future cash flows over a defined period and discounts them back to present value using an appropriate discount rate. More commonly used for businesses with variable or growing earnings, or where a business is in a growth phase with expected future changes in profitability.

Best suited for established, profitable businesses with a reliable earnings history — professional practices, retail businesses, service companies, and manufacturing operations.

Market approach

Values the business by reference to comparable transactions or industry benchmarks.

Comparable sales — analyses recent sales of similar businesses to derive a market value. Adjustments are made for differences in size, location, profitability, and risk. Comparable sales data can be difficult to obtain for private businesses.
Industry multiples — uses industry-specific rules of thumb, for example a multiple of revenue, EBITDA, or recurring fees. Common in industries like accounting practices (often valued at a multiple of recurring fees) or medical practices (often valued at a multiple of revenue).

Best suited for businesses in industries where comparable sales data is available — franchises, professional practices, retail businesses with established benchmarks.

Asset-based approach

Values the business based on the net value of its underlying assets.

Going concern value — values the business on the assumption it will continue to operate. Assets are valued at market value (not book value), and goodwill is included. This gives the total enterprise value of the business as an operating entity.
Liquidation value — values the assets on the assumption the business would be wound up and assets sold individually. This typically produces a lower value than going concern, as it does not include goodwill and assets may sell at a discount in a forced sale.

Best suited for asset-intensive businesses (property development, farming, investment holding companies), businesses with minimal goodwill, or businesses that are not profitable.

Key concepts in business valuation

Several concepts are central to business valuation in family law. Understanding these helps you engage meaningfully with the valuation process.

Goodwill

Goodwill is the value of a business above the net value of its tangible assets. It reflects the business's reputation, customer relationships, and earning capacity. Family law distinguishes between two types.

Commercial goodwill — value that exists independently of any individual: brand, location, systems, and established customer base. This is transferable to a buyer.
Personal goodwill — value attributable to the individual owner's personal reputation, skills, and relationships. This cannot easily be transferred to a buyer.

Future Maintainable Earnings and normalisation

Future Maintainable Earnings (FME) is the estimated level of earnings that the business can sustain into the future, based on an analysis of historical performance. Arriving at FME requires normalising the financial accounts — adjusting to remove personal expenses put through the business, one-off or extraordinary items, above- or below-market owner remuneration, and related-party transactions not at arm's length.

Discounts

Minority discount — a reduction applied when the party holds a minority interest (less than 50%) in the business, reflecting the lack of control.
Marketability discount — a reduction reflecting the difficulty of selling a private business interest compared to listed shares.

Value vs price

Value is the theoretical worth of the business based on accepted valuation methodologies. Price is what a willing buyer would actually pay in the market, which may differ from the assessed value. The court is concerned with value, not necessarily what the business might fetch if sold tomorrow.

Choosing a business valuer

The quality of a business valuation depends heavily on the qualifications and experience of the valuer. The court expects valuations to be prepared by appropriately qualified professionals.

Qualifications and experience

Professional qualifications — look for a Chartered Accountant (CA) or Certified Practising Accountant (CPA) with a specialist business valuation qualification. Members of the Business Valuation Specialist (BVS) program or equivalent are preferred.
Family law experience — choose a valuer with experience in family law matters. They should be familiar with the court's expectations, expert witness obligations, and the specific issues that arise in family law business valuations.
Expert witness duties — the valuer's primary duty is to the court, not to the party who engaged them. Their report must be independent, objective, and prepared in accordance with the Family Law Rules 2021 and applicable professional standards.

Single joint expert vs party-appointed experts

The court encourages parties to agree on a single joint expert. This reduces costs, avoids conflicting evidence, and is generally faster. Both parties provide instructions, and both can ask questions of the expert. The expense is typically split equally between the parties.

Where parties cannot agree on a single expert, each party may engage their own valuer. If both parties have their own expert, the court may direct the experts to confer and produce a joint report. Each party bears the full cost of their own expert, typically doubling the total expense.

Valuation cost ranges

Business type	Typical cost range
Simple sole trader or small partnership	$5,000 – $8,000
Small to medium company	$8,000 – $15,000
Complex structures (multiple entities, trusts)	$15,000 – $20,000+
Large enterprises or contested valuations	$20,000+

Challenging a business valuation

A business valuation is an opinion, not a fact. If you disagree with a valuation, there are legitimate grounds on which it can be challenged.

Grounds for challenge

Methodology — the valuation method chosen may not be appropriate for the type of business. For example, using an income approach for a business with erratic earnings, or failing to consider multiple methods to cross-check the result.
Assumptions — key assumptions may be unreasonable: future earnings projections that are too high or too low, inappropriate discount rates or capitalisation multiples, or growth assumptions that do not reflect the business's actual trajectory.
Comparable selection — if the market approach was used, the comparable transactions selected may not be truly comparable: different industries, sizes, locations, or market conditions.
Normalisation adjustments — the adjustments made to normalise the accounts may be incorrect or incomplete. Personal expenses may not have been properly identified, or owner remuneration may have been set at an unrealistic market rate.

How to challenge

Obtain your own valuation. Engage a qualified valuer to prepare an independent valuation. This gives you an alternative opinion to present to the court and helps identify weaknesses in the other party's valuation.
Cross-examine the valuer. At trial, the valuer can be cross-examined about their methodology, assumptions, and conclusions. Effective cross-examination can expose weaknesses in the valuation and reduce the weight the court gives to it.
Request an expert conference. Where both parties have engaged valuers, the court may direct the experts to confer and produce a joint report identifying where they agree and disagree. This narrows the issues for trial.

Court's discretion

The court is not bound to accept any particular valuation. Where competing valuations are presented, the court may prefer one over another based on the quality of reasoning and evidence, adopt a value within the range, or make its own finding. The court will consider which methodology is most appropriate, whether the assumptions are reasonable, and how well the valuer performed under cross-examination.

Small business vs large enterprise

The valuation challenges differ significantly depending on the size and structure of the business. Most family law business valuations involve small to medium enterprises where the owner is actively involved in the business.

Sole practitioners and personal goodwill

For sole practitioners — doctors, dentists, lawyers, accountants, tradespeople — a significant portion of the business value may be personal goodwill tied to the owner's skills and reputation. This is the most contested area in small business valuations.

The business may have limited value without the owner.
Personal goodwill is difficult to transfer to a buyer.
Courts consider how much of the earnings would follow the owner vs stay with the practice.

Partnerships and family companies

Partnerships require valuation of the individual partner's interest, which may be less than a proportionate share of the total partnership value. Family companies present similar issues, with the additional complexity of corporate structures.

Partnership agreements may restrict transfer or sale of interests.
Minority discounts may apply to less-than-50% interests.
Family companies may have complex shareholding structures.

Trusts and beneficial interests

Businesses held through trusts add a layer of complexity. The court must first determine whether the trust interest is property, a financial resource, or neither.

Discretionary trust beneficiaries have no fixed entitlement.
The court examines who controls the trust in practice.
Corporate trustees and appointors are considered.
Historical distributions and the parties' expectations are relevant.

Larger enterprises

Larger businesses with established revenue streams, multiple employees, and systems that operate independently of the owner are generally easier to value because they have more commercial (transferable) goodwill.

More reliable financial records and audited accounts.
Greater commercial goodwill relative to personal goodwill.
More comparable sales data available for the market approach.
May require more complex valuation involving multiple methods.

"Mum and Dad" businesses

Small family-run businesses are among the most commonly disputed assets in property settlements. The value is often contested because there is significant personal goodwill, financial records may be informal, personal and business expenses are intermingled, and the business's viability may depend heavily on both parties' involvement. Early engagement of a qualified valuer can help manage expectations and narrow the issues in dispute.

Common questions

How is a business valued in a family law property settlement?

A business is valued using one or more established valuation methods: the income approach (capitalisation of future maintainable earnings or discounted cash flow), the market approach (comparable sales or industry multiples), or the asset-based approach (net asset value). The method chosen depends on the type, size, and nature of the business. A qualified business valuer prepares a report that estimates the market value of the business interest at a particular date, typically as close to the hearing date as possible.

What is the difference between personal and commercial goodwill?

Commercial goodwill is the value of a business that exists independently of any particular individual — it includes brand recognition, established customer base, location, systems, and reputation. Personal goodwill is the value attributable to the skills, reputation, and relationships of a specific individual. In family law, personal goodwill can be more difficult to value and divide because it cannot be transferred to a buyer. Courts have recognised this distinction, and a business that relies heavily on the owner's personal reputation may have less transferable (and therefore lower) commercial value.

How much does a business valuation cost?

Business valuations for family law purposes typically cost between $5,000 and $20,000 or more, depending on the complexity of the business, the number of entities involved, the quality of financial records, and whether multiple valuation methods are required. Simple sole trader or small partnership valuations are at the lower end, while valuations involving companies, trusts, multiple entities, or complex financial structures will be at the higher end. Using a single joint expert can reduce costs compared to each party engaging their own valuer.

Can I challenge the other party's business valuation?

Yes. You can challenge a business valuation on several grounds, including the methodology used, the assumptions made (such as future earnings projections or discount rates), the selection of comparable businesses, normalisation adjustments to the accounts, or errors in the financial data relied upon. You may obtain your own valuation from a qualified valuer and present it as evidence. At trial, the valuers can be cross-examined about their opinions. The court has discretion to prefer one valuation over another or to adopt a value within the range of the competing valuations.

What date is the business valued at?

Generally, the business is valued as close to the date of the final hearing or trial as possible. This reflects the principle that the court divides the net asset pool at its current value. However, in some circumstances the court may adopt a different date — for example, if one party's conduct since separation has significantly affected the business value, or if there has been a long delay between separation and hearing. The valuation date should be clearly stated in the valuer's report.

Do both parties need their own business valuer?

No. The Family Law Rules 2021 encourage parties to agree on a single joint expert rather than each engaging their own valuer. A single expert reduces costs and avoids the 'battle of experts.' If parties cannot agree on a single expert, each party may engage their own valuer, or the court may appoint one. Where separate valuers are engaged, the court may direct them to confer and produce a joint report identifying areas of agreement and disagreement.

How are trust assets valued in family law?

Trust assets are valued based on the net value of the assets held within the trust. However, whether a trust interest is included in the property pool depends on the degree of control a party has over the trust. Where a party is the appointor, trustee, or primary beneficiary and has effective control, the court may treat the trust assets as that party's financial resources or, in some cases, as property. Discretionary trust interests are more complex because beneficiaries have no fixed entitlement — the court examines the practical reality of control and benefit.

What if the business has declined since separation?

If the business value has declined since separation, the court will generally value it at the current date (close to the hearing). However, the reason for the decline matters. If the decline is due to general market conditions, both parties share the loss. If the operator spouse has deliberately run down the business or failed to maintain it, the court may add back value or attribute a notional higher value. Conversely, if the non-operator spouse's departure caused the decline (for example, they were integral to the business), the court will consider this in its assessment.
