Most business valuation content online is written for one buyer: a founder curious what their company might fetch in a sale. Shareholder disputes and divorce proceedings are a different animal entirely — the valuation isn’t a starting point for negotiation, it’s often the thing being fought over. The methodology decisions made early in these engagements can move the final number by a wide margin, and they rarely get explained in plain language. Here’s what’s actually different.

The First Fight Is Almost Never About the Number – It’s About the Standard

Before anyone talks about multiples or discounted cash flows, a valuation for a dispute has to answer a prior question: valued under what standard? The two most common are fair market value (what a willing buyer would pay a willing seller, neither under compulsion) and fair value (a related but distinct standard used in oppression remedy cases, which asks what’s equitable between the parties rather than what a hypothetical third party would pay).

The distinction isn’t academic. In a shareholder oppression claim under the CBCA or a provincial business corporations act, courts have generally been reluctant to let a majority shareholder buy out a minority holder at a discounted price simply because that holder lacks control — the logic being that a squeeze-out shouldn’t be rewarded with a bargain valuation. In a straightforward fair-market-value context, by contrast, a lack of control or lack of marketability can be a legitimate factor in the analysis. Which standard applies is often set by the nature of the dispute itself, and getting it wrong at the outset can produce a defensible-looking report that answers the wrong question.

The Valuation Date Can Matter More Than the Method

Choosing when to value the business is frequently more contentious than choosing how. In a marital dissolution, the relevant date might be the date of separation, the date of the agreement, or the date of trial, depending on the jurisdiction and the facts — and in a business that’s grown or shrunk materially over that period, the choice can swing the outcome by a large margin. In a shareholder dispute, the triggering event (a resignation, a termination, a breach of a shareholders’ agreement) usually sets the date, but disputes still arise over whether subsequent events — a large contract won the following month, a lawsuit settled the following year — should inform the valuation or be treated as hindsight.

Discounts Are Where Most of the Real Argument Happens

Two discounts show up in nearly every contested valuation, and both are genuinely contestable rather than mechanical:

  • Discount for lack of control (minority discount): reflects that a non-controlling interest can’t unilaterally direct dividends, strategy, or a sale. Courts scrutinize this heavily in oppression contexts for the reasons above, and family law courts take varying views depending on the province and the specific facts of who controls the business post-separation.
  • Discount for lack of marketability: reflects that shares in a private company can’t be sold quickly or easily, unlike a public stock. This one survives scrutiny more often than the control discount, but its size is frequently disputed — is it 10%, 20%, 35%? — and this is usually where a well-supported, empirically grounded valuation earns its credibility.

Independence Is the Whole Point

In litigation, a valuation prepared by an advisor with a pre-existing relationship to one party, or built on assumptions handed down rather than independently tested, tends to lose credibility fast — whether in front of a judge, an arbitrator, or opposing counsel. The valuations that hold up are the ones built to a recognized professional standard (in Canada, typically the CICBV’s practice standards for Chartered Business Valuators), with assumptions disclosed, methodology cross-checked across more than one approach, and conclusions that would survive a cross-examination on how they were reached — not just what they concluded.

Family Businesses Add a Layer Most Frameworks Don’t Address

A meaningful share of these engagements involve businesses where the disputing parties still have to coexist — siblings who inherited a company together, spouses who remain co-parents, business partners who built something over decades. The valuation itself is a technical exercise, but the engagement around it benefits from an advisor who understands that the number isn’t the only thing at stake, and who can produce a report that both sides’ counsel can actually engage with rather than immediately dismiss.

Where This Fits at Alphabridge

This is a corner of business valuation that’s often handled by generalist litigation support practices rather than dedicated valuation specialists. Our business valuation practice is built around the same rigor we bring to M&A and financing valuations — multiple methodologies, disclosed assumptions, and a report built to withstand scrutiny — applied to the specific standards and pressures that shareholder disputes and family law matters require.
