Divorce and Business Valuation: The UK Guide

Why divorce valuations are their own discipline

A business valuation for divorce is not the same exercise as a valuation for a sale, an EMI grant or an HMRC filing. The audience is a family court. The standard is fairness between spouses under the Matrimonial Causes Act 1973, not market value to a hypothetical buyer. The evidential threshold is what a single joint expert can defend under cross-examination, not what a broker can hint at in a pitch.

Getting this wrong is expensive. An inflated valuation forces a settlement the paying spouse cannot fund without selling the business. An understated valuation deprives the other spouse of a fair share. Either outcome produces years of post-order litigation and, frequently, a forced sale that destroys the value both parties were fighting over.

The legal framework in one page

English family courts apply the section 25 MCA 1973 factors when dividing assets on divorce. In relation to a private company, the court is concerned with three linked questions:

• What is the business worth today, on a defensible independent basis?
• Is that value a matrimonial asset, a non-matrimonial asset, or a mix (typically where the business pre-dates the marriage)?
• How is that value realised to produce a fair division without forcing the underlying business to be sold?

The seminal cases - *Miller / McFarlane* [2006], *Wells v Wells* [2002], *Martin v Martin* [2018] - establish that the court will not treat business value as if it were cash in a bank account. A "Wells sharing" order (dividing the shares themselves between spouses) is one option; a lump sum, staged payments, or a Mesher-style deferred order are others.

The valuation feeds every one of these decisions. It is not a background document.

The single joint expert - and why the instructions matter

In almost every English divorce involving a private company, the court directs the parties to appoint a Single Joint Expert (SJE) under Part 25 FPR 2010. The SJE:

• Is jointly instructed and jointly paid.
• Reports to the court, not to either spouse.
• Is subject to Part 25 duties of independence and can be cross-examined at final hearing.

The instructions letter is the document that shapes the entire report. A well-drafted letter of instruction addresses, at minimum:

• The valuation date (typically date of separation or date of report, per case law).
• The basis of valuation (fair value between spouses, not open-market value with discounts).
• Whether minority and marketability discounts apply, and if so on what basis.
• Treatment of directors' loan accounts and shareholder debt.
• Latent tax on a notional sale, and the assumed disposal route.
• Liquidity assessment: what could realistically be extracted without harming the business.

Sloppy instructions produce a report the court cannot use. A tight letter, agreed between both solicitors before the SJE is appointed, is the single highest-return step in the process.

Fair value, not market value: the discount debate

The most contested issue in divorce valuations is whether minority and marketability discounts apply.

• In a sale to a third party, a 30% shareholding would normally attract a minority discount and a marketability discount, potentially reducing pro-rata value by 40-60%.
• In a divorce between spouses, the court's task is fair division. Where one spouse has always exercised control and the other spouse's stake is a marital asset ancillary to that control, the courts have repeatedly refused to apply hypothetical discounts that would benefit only the controlling spouse.

*Versteegh v Versteegh* [2018] confirms that valuation of private companies is "an art, not a science", and that the court is entitled to look through mechanical discount conventions where they produce an unfair result. *Martin v Martin* [2018] took the same approach on latent tax.

Practical implication: the SJE will usually be asked to produce two figures - a fair-value figure between spouses and an open-market figure - and to explain the difference. Both are needed. Neither is right on its own.

Liquidity: the number that decides the outcome

A private company valuation without a liquidity analysis is useless in divorce proceedings. The court needs to know:

• How much cash can be extracted from the business as dividends over what period, without impairing trading capacity?
• What debt capacity does the business have that could support a bank-funded lump sum to the departing spouse?
• Would a third-party sale be required to fund the settlement, and if so, at what cost to headline value?
• What is the tax cost of each extraction route (income tax on dividends, CGT on a share buy-back or third-party sale, BADR eligibility)?

A £4m equity valuation from which £200,000 a year can be safely extracted supports a very different order to a £4m equity valuation with £1.5m of surplus cash and £2m of unused debt capacity. The same headline number, two entirely different settlements.

Pre-marital value and passive growth

Where a business pre-dates the marriage, part of the current value may be non-matrimonial and therefore not subject to sharing (though still available for needs). This requires the SJE to model:

• The value of the business at the date of the marriage.
• The value at the valuation date.
• The extent to which growth was driven by the spouse's active efforts during the marriage (matrimonial) versus passive market or sector uplift (arguably non-matrimonial).

This is a genuine valuation exercise. It is not a straight-line apportionment. Sector benchmarks, comparable transaction evidence and a defensible narrative of what drove growth are all required.

*Standish v Standish* [2025] (UK Supreme Court) has sharpened the analytical framework here, and any valuation prepared without reference to the current authorities is unlikely to survive challenge.

The five most common mistakes we see

1. Using a "quick" accountant's valuation as an opening position. The other side's SJE will pull it apart, the client loses credibility, and the eventual settlement is worse than if no number had been offered.

2. Ignoring latent tax. The court expects a realistic assessment of the CGT that would arise if value were extracted. Ignoring it inflates the number the paying spouse must fund.

3. Applying private-sale discounts by default. In many divorce cases, they do not apply. Applying them without justification looks partisan and undermines the whole report.

4. Missing debt-like items and directors' loans. A £400,000 director's loan credit balance is £400,000 of shareholder wealth, not company value. Missing it produces a materially wrong equity number.

5. Producing a valuation without a liquidity section. Without it, the court cannot craft an order that is deliverable. The report gets sent back.

What a court-ready divorce valuation contains

The SJE report that stands up in a final hearing has a consistent shape:

• Stated valuation date and basis (fair value between spouses, with an open-market cross-check).
• Methodology (earnings, assets, hybrid) with reasons.
• Normalised EBITDA with each adjustment evidenced.
• Multiple derived from genuinely comparable UK SME transactions, not aspirational broker chatter.
• Explicit treatment of excepted assets, surplus cash and shareholder loans.
• Reasoned position on minority and marketability discounts.
• Latent tax on notional realisation, with route options.
• Full liquidity analysis (dividends, debt capacity, buy-back options).
• Pre-marital value where relevant, with reasoning.
• A single joint expert declaration under Part 25 FPR 2010.

When to commission the valuation

The earlier, the better. In practice:

• Before Form E is exchanged, so the disclosure narrative is accurate.
• Before the First Directions Appointment, so the SJE letter of instruction is informed.
• Certainly before any Financial Dispute Resolution appointment, where a judge will indicate a settlement range that anchors the rest of the case.

Every week that passes without a defensible number is a week in which positions harden around estimates. The party who arrives with a properly evidenced valuation, presented through a Single Joint Expert or a shadow expert brief, controls the framing of the entire negotiation - and, in most cases, materially improves the eventual outcome.

Divorce is one of the few valuation contexts where the number decides not just a transaction but the shape of two futures. It deserves the same evidential rigour a sale process would receive, and more.
