If you own a business and are separating from your spouse, the business may become one of the most important financial issues in your divorce. In Ontario, separation does not normally mean that your spouse automatically becomes an owner of your company. However, the value of your interest in the business may form part of the equalization calculation used to divide property between married spouses.
Business ownership can make this process more complicated. The parties may need to determine what the business was worth when they separated, what it was worth when they married, and whether corporate income or retained earnings should also be considered for support purposes.
In Ontario, a business interest is generally included in the owner’s net family property. The focus is usually on determining its value, rather than dividing the company or its shares equally between spouses.
A Business Interest May Form Part of Equalization
Ontario generally divides the value of property between married spouses through a process called equalization, rather than dividing ownership of each individual asset. A spouse’s shares in a corporation, partnership interest, or other business interest may therefore need to be valued and included in that spouse’s net family property. However, the other spouse does not automatically receive half of the shares or become a business partner simply because the parties separate.
When determining the value of the business interest for equalization purposes, a business owner may also be entitled to deduct any notional taxes that would be associated with the sale of their shares. In other words, the potential tax liability arising from a sale may reduce the value of the business interest included in the owner’s net family property.

A Business Owned Before Marriage May Still Affect Equalization
Owning a business before getting married does not necessarily mean that the entire value of the business is removed from the equalization calculation.
Under Ontario’s net family property regime, a spouse can generally deduct the net value of qualifying property that they owned on the date of marriage. If a business was worth $500,000 when the parties married and substantially more when they separated, for example, establishing the business’s date-of-marriage value may significantly affect the equalization calculation.
The difficulty is often proving what the business was worth many years earlier. Historical financial statements, corporate tax returns, shareholder records and other business records may become important. A retrospective valuation may also be required.
For a business owner, keeping reliable historical corporate and financial records can therefore become particularly important when determining the financial consequences of separation.

The Business Is Generally Valued as of the Date of Separation
Determining what a privately held business is worth can be one of the more complicated parts of a high-net-worth divorce. For equalization purposes, the relevant date is generally the date the spouses separated with no reasonable prospect that they would resume cohabitation.
A business cannot always be valued by looking at its bank balance or the value shown on its financial statements. Depending on the business, a valuation may consider its assets and liabilities, earnings, business trends, and the value that a willing purchaser might pay for the business or ownership interest.
Additionally, a successful business may be worth considerably more than its equipment, inventory and cash. Its value may also include goodwill. Goodwill can arise from matters such as an established customer base, business relationships, reputation, systems, contacts and other features that allow the business to generate income.
A Chartered Business Valuator or other financial expert may therefore be required in a separation involving a privately held company. The appropriate valuation method will depend on the nature of the business.
The valuation is generally based on information that was available as of the date of separation. Later events cannot simply be used with hindsight to change what the business was worth at separation, although post-separation information may sometimes assist in assessing whether assumptions made about the business as of that date were reasonable.

Business Owners Must Provide Detailed Financial Disclosure
A privately held corporation does not prevent a spouse from having to disclose relevant business information. Ontario’s Family Law Rules impose specific financial disclosure requirements where property claims are made.
For an interest in a privately held corporation, the required disclosure can include the corporation’s and its subsidiaries’ financial statements for each of the three years preceding the valuation date. Where the spouse has a majority interest, corporate income tax returns for that period may also be required.
A sole proprietor or self-employed person may similarly be required to provide business or professional financial statements and personal income tax returns, including the materials filed with those returns.
This information can be important not only in determining the value of the business, but also in determining the business owner’s income for support purposes. For more information about financial disclosure from a self-employed spouse, click here.

Corporate Income Can Also Affect Support
Valuing a business for equalization and determining a business owner’s income for support are related but distinct issues.
A business owner may receive salary, dividends, or other benefits, while some earnings may remain inside the corporation for legitimate business purposes. Retained earnings are not automatically treated as money personally available to the business owner. A company may have legitimate reasons to retain funds for inventory, debt repayment, working capital, expansion or other business needs.
Courts may examine the corporation’s finances and the owner’s control over the company when determining income available for support. As a result, this can make support calculations involving business owners more complicated than simply looking at the income reported on a personal tax return.

Equalization Does Not Necessarily Require the Business to Be Sold
Separation does not necessarily mean that a business must be sold. Equalization generally creates a financial obligation between spouses, and the Family Law Act gives courts flexibility in how an equalization payment may be satisfied, including through security, a transfer of property, or payments over time in appropriate circumstances.
Business owners should preserve corporate financial statements, tax returns, shareholder agreements, minute books, banking records and records showing ownership when separation begins. Early legal and valuation advice can help identify the information required while minimizing unnecessary disruption to the business.
The appropriate solution will depend on the value of the business, the amount of the equalization payment, the owner’s available assets and liquidity, and the circumstances of the parties.

High-Net-Worth Divorce Involving a Business Requires Careful Valuation
For a business owner, the central issue in an Ontario divorce is usually not whether the other spouse will simply receive half of the company. The more important questions are what interest the business owner actually owns, what that interest was worth at separation, what value may be deductible from the date of marriage, and how the resulting figures affect equalization and support.
These cases can require input from family lawyers, accountants and business valuators. Reliable financial disclosure and an accurate valuation can be important to both protecting the ongoing business and ensuring that the financial issues arising from the separation are properly addressed.
Business owners who are separating should obtain legal advice about how their business interests may affect property division and support.
