If you own a business, divorce adds a layer of complexity that can threaten years of hard work. Your business is likely one of your most valuable assets, and in many cases, it's also your primary source of income. Understanding how courts value and divide business interests is essential for protecting what you've built while meeting your legal obligations to your spouse.

This guide covers how businesses are treated in Canadian divorces, from valuation methods to protection strategies. If you're looking at the broader picture of property division, see our guide to property division in Canada. If you're considering a prenuptial agreement to protect a business, see our prenup guide.

Is Your Business Considered Family Property?

The short answer is: almost certainly, at least in part. If you started the business during the marriage, the full value of the business is generally considered family property and is subject to division. If you started the business before the marriage, the value at the date of marriage may be excluded, but any increase in value during the marriage is typically divisible.

Gifts and inheritances used in the business may be excluded from division, but this varies significantly by province. In Ontario, for example, excluded property includes gifts and inheritances received during the marriage, but if those funds were commingled with business assets, they may lose their excluded status.

Even if you started your business before the marriage, any increase in value during the marriage is likely subject to division. If the business was worth $100,000 when you married and $500,000 when you separated, the $400,000 increase is generally considered family property. The original $100,000 may be excluded depending on your province.

The treatment also depends on whether you're the sole owner, a partner, or a shareholder. If other people have ownership interests in the business, only your share is considered family property. Third party shareholders' rights are protected, and a court cannot force a transfer of shares that would violate a shareholders' agreement.

How Businesses Are Valued

Business valuation is one of the most contested aspects of a divorce involving business interests. Courts typically rely on one of three standard approaches, and a Chartered Business Valuator (CBV) is usually engaged to provide an expert opinion.

Valuation MethodHow It WorksBest For
Asset basedTotal assets minus total liabilities (book value or fair market value of individual assets)Asset heavy businesses: real estate, manufacturing, holding companies
Income basedProjected future earnings capitalized or discounted to present valueProfessional practices, service businesses, consulting firms
Market basedComparison to what similar businesses have recently sold forRetail stores, franchise businesses, restaurants

The choice of valuation method can dramatically affect the result. A profitable consulting firm with few physical assets might be worth very little under an asset based approach but very valuable under an income based approach. This is why business valuations in divorce are often heavily contested, with each side's expert reaching different conclusions.

The Goodwill Question

Goodwill is the intangible value of a business above its tangible assets. It includes things like brand recognition, customer relationships, and reputation. There's an important distinction between enterprise goodwill (value that would transfer if the business were sold) and personal goodwill (value tied to the owner personally, such as a doctor's reputation). Most provinces include enterprise goodwill in the business value, but the treatment of personal goodwill varies.

Simple business valuation (sole proprietor, few assets)

$5,000 to $10,000

Single expert

Moderate complexity (partnerships, multiple revenue streams)

$10,000 to $25,000

May need forensic accountant

Complex valuation (corporations, multiple entities, international)

$25,000 to $50,000+

Often dueling experts

Protecting Your Business

The best time to protect your business from a divorce is before you get married. But even during a marriage, there are steps you can take to minimize the impact of a potential separation:

Business Protection Strategies

Get a prenuptial or marriage contract specifying the business as excluded property
Keep personal and business finances strictly separate (no mixing personal and business bank accounts)
Avoid using marital funds (joint savings, home equity) to invest in the business
Keep accurate records of the business's value at key dates (marriage, major investments)
Have a shareholders' agreement with buy sell provisions that address divorce
Pay yourself a reasonable market rate salary rather than reinvesting all profits
Document any pre-marriage value with a professional valuation
If your spouse works in the business, have a clear employment agreement

Income vs. Property

A business creates two things that matter in a divorce: property value (what the business is worth) and income (what it generates for the owner). Both are relevant, but they're used for different purposes. The property value is divided as part of equalization or property division. The income affects child support and spousal support calculations.

This dual nature creates a specific challenge: if the court uses a high business value for property division and a high income for support, the business owner can feel like they're paying twice. Competent legal and financial advice is essential to ensure the interplay between property value and income is handled fairly.

Income Imputation

Courts have broad powers to impute income to a business owner who is not paying themselves a reasonable salary. Section 19 of the Federal Child Support Guidelines allows courts to determine income based on what the parent could reasonably be expected to earn, not what they actually pay themselves. Retained earnings, personal expenses paid through the business, and corporate distributions are all examined.

Paying yourself an artificially low salary to reduce your support obligations is one of the most common mistakes business owners make in divorce. Courts see through this strategy every time. A judge can impute income based on what a reasonable salary would be for your role, the business's historical profits, and personal expenses the business pays on your behalf. Attempting to minimize income usually results in a worse outcome and damaged credibility.

Dividing the Business

Once the business has been valued, there are several options for how to handle the division:

Buyout

The business owner pays the other spouse their share of the business value. This can be done in a lump sum or through payments over time. A buyout preserves the business intact and allows the owner to continue operating without disruption.

Offset

Instead of paying cash for the other spouse's share, the business owner gives up value in other assets. For example, if the business is worth $500,000 and the home equity is $500,000, one spouse might keep the business while the other keeps the home. This avoids the need for a cash payment.

Sale

The business is sold and the proceeds are divided. This is usually the least desirable option because selling under time pressure often results in a lower price. However, it may be the only option if neither spouse can afford a buyout and there aren't enough other assets for an offset.

Continued Co-Ownership

In rare cases, both spouses continue to own and operate the business together after separation. This only works if both were already actively involved and can maintain a professional working relationship. Most lawyers advise against this option.

Most family lawyers recommend a buyout or offset rather than a forced sale. Selling a business under the time pressure of a divorce almost always results in a lower price than the business is actually worth. If a buyout is the chosen approach, structured payments over 2 to 5 years can make it more manageable.

Corporate Structure Considerations

The structure of your business affects how it's treated in a divorce:

Holding Companies and Trusts

If your business operates through a holding company or family trust, the analysis becomes more complex. Courts will look through corporate structures to determine the true value of your business interests. A holding company doesn't shield assets from division; it just makes the valuation more complicated and expensive.

Shareholders' Agreements

If you have business partners, your shareholders' agreement may include provisions that address what happens in a divorce. Buy sell provisions (also called shotgun clauses) may be triggered, and the agreement may restrict the transfer of shares. Courts generally respect shareholders' agreements, which means your spouse may not be able to receive actual shares in the company. Instead, they would receive the cash equivalent of their entitlement.

Professional Corporations

Doctors, lawyers, accountants, and other professionals who operate through professional corporations face unique rules. In most provinces, only the licensed professional can own shares of a professional corporation, which means shares can't be transferred to a spouse. However, the value of those shares is still subject to division.

Resources and Next Steps

Divorcing with a business is one of the most complex family law situations. You need a family lawyer who understands business valuation, a Chartered Business Valuator or forensic accountant, and possibly a tax advisor. The investment in professional advice is significant, but the cost of getting it wrong is much higher.

Can my spouse take my business?
Your spouse generally cannot take ownership of your business. What they can receive is their share of the business's value as part of property division. This is typically handled through a cash buyout, an offset against other assets, or in rare cases a court ordered sale. The business itself usually stays with the operating spouse.
Do I have to sell my business in a divorce?
No. A forced sale is a last resort and courts generally try to avoid it. If you can afford to buy out your spouse's share, offset it against other assets, or arrange structured payments over time, the court will typically prefer those options. A sale is usually only ordered when no other practical option exists.
What if my spouse worked in the business?
If your spouse worked in the business, they may have a claim for both property division (their share of the business value) and for compensation for their contributions. Courts may also consider the fact that one spouse's career was advanced through the other's unpaid labour. Additionally, if your spouse is currently employed by the business, the divorce may require addressing their ongoing employment or severance.
Can I restructure my business before the divorce?
Be very careful. Restructuring a business during or just before a separation to reduce its apparent value is something courts watch for closely. Moving assets out of the operating company, creating new entities, or changing compensation structures can be viewed as an attempt to hide or reduce value. Courts have broad powers to undo transactions that are designed to defeat a spouse's property claims.
What about business debts?
Business debts are generally deducted from the business value when calculating net worth. If the business has $500,000 in assets and $300,000 in debt, the net business value is $200,000. However, courts may scrutinize debts incurred close to the separation date, especially if they appear to be inflated or unnecessary. Personal guarantees on business loans are also relevant to the overall financial picture.
