Should You Engage a Forensic Accountant For Your Divorce?

Divorce proceedings involving anything beyond straightforward employment income and a family home will usually need forensic accounting input. Business interests, self-employment income, property portfolios, trust structures, pension sharing, and tax consequences all create complexity that general accountants and audit firms aren't equipped to handle in a litigation context. This guide explains how forensic accountants support solicitors in divorce cases and why getting the financial analysis right is critical to achieving fair settlements. Whether you're considering hiring a forensic accountant for a matrimonial dispute or trying to decide between a single joint expert and party-appointed instruction, we cover the key issues below.

At Jack Ross, we've provided forensic accounting services in matrimonial finance since 1948. We work with family law solicitors across the UK, acting as both party-appointed experts and single joint experts in financial remedy proceedings.

Why divorce cases need forensic accountants

The court's objective in financial remedy proceedings is to achieve a fair outcome and resolve the financial dispute under s.25 Matrimonial Causes Act 1973. A forensic accountant can help solicitors understand their client's financial situation and ensure the court sees the true picture of the matrimonial assets. When one or both parties have business interests, complex finances, or reasons to obscure the true position, that picture doesn't come together without forensic analysis.

Since White v White [2001] UKHL 54 established the 'yardstick of equality', the court needs to know the full value of the matrimonial estate before it can reach a fair divorce settlement. And since Sharland v Sharland [2015] UKSC 60, it's clear that non-disclosure can unravel an entire settlement - even years later. A forensic accountant's role is to ensure that the financial evidence before the court is complete, accurate, and reliable.

The Family Procedure Rules Part 25 governs the instruction of experts in family proceedings. The court must be satisfied that expert evidence is necessary, that the questions can't be answered by the parties themselves, and that the instruction is proportionate. Forensic accountants are among the most commonly approved experts in financial remedy cases, particularly where complex financial matters require specialist accountancy skills.

What a forensic accountant does in divorce

We specialise in forensic accountancy for divorce and our team handles financial matters across the full range of court proceedings. The scope of work varies, but typically covers one or more of the following:

Income determination. For employed individuals, income is usually clear from payslips and P60s. For the self-employed, company directors, and those with multiple income sources, it's not. The forensic accountant analyses accounts, tax returns, bank statements, and company records to determine true income - including benefits in kind, dividends, director's loan account drawings, and income sheltered through corporate structures.

Business valuation. Where one or both parties own business interests, the forensic accountant values them. This goes beyond simply applying a multiple to profits. A proper business valuation considers maintainable earnings, the appropriate multiple, minority discounts, illiquidity discounts, and the distinction between the value of the business and the income it generates. The methodology matters - an earnings-based valuation will produce a very different figure from an asset-based one, and the forensic accountant must justify the approach.

Reviewing Form E disclosure. The forensic accountant reviews the other party's Form E for completeness, consistency, and accuracy. Common issues include: understated income, omitted assets, overvalued liabilities, and inconsistencies between the Form E figures and the supporting documents.

Tax advice on settlement options. Different ways of dividing the assets have different tax consequences. Transferring property triggers Capital Gains Tax (after the tax year of separation). Pension sharing has income tax implications for the recipient. Extracting capital from a company may incur Corporation Tax, Income Tax, or both. The forensic accountant models the tax cost of different financial settlement scenarios so the solicitor and client can make informed decisions. In mediation, this analysis helps both parties and the mediator understand the true cost of proposed settlement structures.

Hidden assets and income suppression

Finding hidden assets is one of the most valuable things a forensic accountant does in divorce proceedings. An ex-partner who controls the business finances has ample opportunity to obscure the true position. Common concealment techniques include:

• Understating business income - cash not put through the books, invoices delayed, work in progress undervalued
• Overstating business expenses - personal expenditure run through the company, inflated supplier invoices, payments to connected parties for services not rendered
• Using director's loan accounts to extract value that doesn't appear as income on tax returns
• Transferring assets to family members, trusts, or offshore structures before proceedings - as examined in Prest v Petrodel Resources Ltd [2013] UKSC 34, the court can pierce the corporate veil in limited circumstances
• Cryptocurrency holdings - increasingly common and harder to detect without forensic analysis of bank statements showing purchases from exchanges
• Overpaying HMRC and receiving refunds after the settlement

A forensic accountant's lifestyle analysis compares declared resources against actual spending patterns. If the sums don't add up, the court is entitled to draw inferences. In our experience, the disparity between declared income and actual lifestyle is the single most common finding in matrimonial forensic work.

Forensic techniques for tracing assets include bank statement reconstruction, analysis of company and trust accounts, property and land registry searches, and cross-referencing disclosed assets against Companies House records and offshore registries where information is available.

Business valuations in divorce

Business valuations in divorce are contentious because the parties' interests are directly opposed. The business owner wants a low valuation. The other spouse wants a high one. The forensic accountant's job is to produce an independent valuation that the court can rely on.

Key issues that arise in matrimonial business valuations:

• Maintainable earnings - what level of profit is sustainable, stripped of one-off items and the effects of manipulation?
• The appropriate earnings multiple - this depends on the industry, the size and growth profile of the business, and comparable transactions. Getting the multiple wrong by even one point changes the valuation by the full amount of maintainable earnings.
• Personal goodwill vs enterprise goodwill - in professional practices and owner-managed businesses, much of the goodwill may be personal to the owner. This affects both the valuation and the question of whether the value is 'realisable' or notional.
• The valuation date - usually the date of trial unless the court directs otherwise. If the business has changed significantly since separation, the choice of date can shift the valuation substantially.

How to instruct a forensic accountant for divorce

Under FPR Part 25, the court must grant permission before an expert can be instructed in family proceedings. The application should set out:

• Why expert evidence is necessary (not just helpful)
• The specific questions the forensic accountant will address
• The estimated cost and time required
• Whether a single joint expert or party-appointed expert is appropriate

Single joint experts are the default in family proceedings and are appropriate where the financial issues are complex but not fundamentally contested. Where the parties' positions are far apart - particularly in cases involving allegations of non-disclosure or fraud - party-appointed experts may be more appropriate, allowing each side's forensic accountant to scrutinise the other's analysis.

When instructing us, we ask solicitors to provide: the petition, Form E and supporting documents, any questionnaire responses, the order for directions specifying the expert's role, and a clear list of questions. The clearer and more focused the questions, the more efficient and cost-effective the forensic work will be.

Costs

Forensic accounting fees in divorce cases depend on the complexity of the finances. A business valuation for a sole trader or small limited company typically costs £3,000 to £5,000. Complex valuations involving groups of companies, multiple income streams, or international elements can cost £6,000 to £12,000.

Income determination and Form E review work is usually charged at hourly rates of £200 to £300, with typical costs of £2,000 to £5,000 depending on scope.

Court attendance adds £1,500 to £2,500 per day.

In single joint expert appointments, the cost is shared between the parties. In party-appointed instructions, each party bears their own expert's costs. Under FPR 28.3, costs orders in financial remedy proceedings are less common than in civil litigation, though the court retains discretion to order costs where a party's conduct has been unreasonable.
