When a marriage or common-law relationship ends and one or both spouses own a business, determining the value of that business becomes one of the most complex — and consequential — aspects of the separation. Business valuation in a family law context requires specialized expertise, careful documentation, and a thorough understanding of Ontario’s equalization framework.
Under Ontario’s Family Law Act, there is a process for division of property based on each party’s net family property (NFP) upon separation. Business interests — whether a sole proprietorship, a partnership, shares in a private corporation, or a professional practice — form part of that NFP and must be accurately valued.
The value assigned to a business can significantly affect the equalization payment owed by one spouse to the other. Undervaluing or overvaluing a business can result in an unfair outcome, making it essential that valuations are conducted rigorously and by a qualified professional.
Business valuations in family law matters are typically performed by a Chartered Business Valuator (CBV) — a professional with specialized training in the valuation of privately held businesses. In contested cases, each spouse may retain their own CBV, resulting in competing valuations that courts must weigh and reconcile.
A CBV will examine a range of documents and information, including:
There is no single method for valuing a business in family law proceedings. The appropriate approach depends on the nature of the business, its size, its industry, and the purpose of the valuation.
The income approach values a business based on its capacity to generate future earnings. Two common techniques include:
The asset approach values the business based on the fair market value of its underlying assets, less its liabilities. This method is commonly used for holding companies or businesses whose value lies primarily in their assets rather than their earnings.
The market approach values the business by reference to the sale prices of comparable businesses or transactions in the same industry. This method relies on the availability of relevant market data, which can be limited for smaller or highly specialized businesses.

Business valuation disputes are among the most hotly contested issues in family law litigation. It is common for the valuations prepared by each party’s expert to differ substantially — sometimes by hundreds of thousands or millions of dollars. Courts must assess the methodology, assumptions, and credibility of each valuator in determining what value to assign.
Key areas of dispute often include:
If a spouse owned an interest in the business before the marriage, the value of that interest at the date of marriage may be deducted from the NFP calculation, reducing the equalization payment. Establishing this pre-marriage value often requires reconstructing historical financial records, which can be both difficult and expensive.
Proper recordkeeping from the outset of a business — and certainly before entering a marriage — is invaluable in protecting a spouse’s pre-marital interest.
Even once a value is agreed upon or determined, there can be significant practical challenges. Equalization payments are owed in cash, but a business interest is an illiquid asset. The business-owning spouse may need to:
These liquidity challenges require careful planning and legal strategy to ensure that the equalization obligation can be met without jeopardizing the ongoing viability of the business.
Business owners facing separation should consider taking proactive steps to protect their interests, including:
For those not yet facing separation, a well-drafted marriage contract can expressly address the treatment of business interests, including exclusions or caps on value for equalization purposes. This is one of the most effective tools available to business owners to reduce risk and uncertainty.
