Divorce for Business Owners in Ontario: What Happens to Shares, Income & Valuation?

Issue
What are the legal principles governing the division of business shares, determination of income for support purposes, and financial disclosure obligations when a business owner divorces in Ontario under the Family Law Act?

  1. Equalization of Net Family Property

Section 5(1) of the Family Law Act provides that when a divorce is granted or spouses separate with no reasonable prospect of reconciliation, the spouse whose net family property is lesser is entitled to one half the difference between the two net family properties. 

Section 4(1) defines net family property as the value of all property a spouse owns on the valuation date, after deducting the spouse’s debts and liabilities, and the value of property (other than a matrimonial home) owned on the date of marriage, after deducting debts and liabilities calculated as of the marriage date. The term “property” is broadly defined as any interest in real or personal property, including business interests and corporate shares. Tangible assets include equipment, inventory, and real property. Intangible assets include client relationships, and intellectual property. Historical and projected earnings, industry conditions, economic outlook, and the degree of control represented by shares (majority versus minority) all influence value.

An example can help illustrate how the equalization of net family property would work in practice. If a business is worth $300,000 on the separation date but grows to $600,000 by the trial date two years later, only the $300,000 separation date value is included in net family property calculations. Alternatively, if both spouses entered the marriage with no assets and one spouse built a business worth $400,000 during the marriage while the other accumulated $100,000 in non-registered investments, the business owner spouse would owe an equalization payment of $150,000 (half the $300,000 difference between their net family properties).

  1.  Income Determination for Business Owners

Determining income for child and spousal support purposes presents distinct challenges when one spouse owns or controls a business. Unlike salaried employees whose income is readily ascertainable from T4 slips, business owners have significant discretion over how they extract value from their businesses and structure their compensation. Section 15 of the Child Support Guidelines establishes that a parent’s or spouse’s annual income is determined by the court in accordance with sections 16 to 20. However, parties may agree in writing about annual income if the court considers the amount reasonable.

Section 18 of the Child Support Guidelines addresses income determination where a parent or spouse is a shareholder, director, or officer of a corporation. Section 18 grants courts discretion to look beyond reported salary or dividends to underlying corporate income. Therefore, business owners are prevented from minimizing support obligations by leaving profits in the corporation or paying themselves minimal salaries while enjoying corporate benefits.

Section 18(2) specifically addresses non-arm’s length transactions, requiring that excessive payments to related parties be added back to corporate income unless proven reasonable. This prevents business owners from reducing apparent corporate profitability by paying inflated salaries to family members or related entities.

  1. Financial Disclosure Obligations

The business owner bears the burden of providing accurate financial information about the business to enable proper valuation. Rule 13 of the Family Law Rules requires parties to serve specific documentation, including: financial statements of any business or professional practice, personal income tax returns for the three years preceding the valuation date, partnership agreements if applicable, and corporate financial information. This rule also requires parties to confirm service by serving a certificate of financial disclosure together with required documents. 

The disclosure obligation is immediate and ongoing throughout family law proceedings. Non-compliance carries serious consequences, as Rule 1(8) provides courts with authority to strike claims where parties fail to disclose financial information or ignore court orders.

Conclusion 

Business owners must understand that their business interests will be valued and included in property division, regardless of whether they wish to maintain sole ownership and operation. The non-owner spouse’s entitlement is to an equalization payment, not to shares in the business itself; however, funding that payment may require liquidating business assets, refinancing, or arranging payment over time.

For income determination, business owners cannot minimize support obligations simply by reducing reported salary or retaining earnings in the corporation. Courts will examine the economic reality of funds available for support purposes, potentially attributing significantly higher income than what appears on personal tax returns.

Comprehensive disclosure obligations force business owners to be prepared to provide extensive documentation about their business affairs. Failure to disclose can result in claims being struck, meaning the business owner may lose their ability to defend against claims or advance their own position.
