We spoke with Lisa Gelman, founder of Gelman & Associates, about the process of dividing a business during a divorce in Ontario. For over 20 years, the Toronto business owner and entrepreneur lawyers at Gelman & Associates have been helping individuals with family law matters.
Please note that these answers are not intended to act as legal advice, but instead act as a general overview of a legal topic. For more specific answers related to your separation or divorce in Ontario, we recommend you contact our law firm for a free consultation with a family lawyer.
Will A Business Be Divided During a Divorce?
There are provincial laws in place for dividing property when a marriage ends. Typically, both spouses take an even split of the property they have acquired over the course of the marriage. For property that one of the spouses had prior to the marriage, the equal split is based on the amount by which the property value increased from the date of the marriage to the date of separation. This process is referred to as the equalization of net family property.
A business is considered net family property in many cases. If there is no pre-nuptial agreement or marriage contract stating otherwise, the value of a business may be split between both spouses following a divorce. Depending on the specific circumstances, there are several ways this split may be calculated. Our Toronto division of property lawyers can help clients understand how business interests fit into a broader equalization analysis.
- Joint Ownership: If both parties own the business equally, then the value of the business will be attributed to both spouses in their financial statements. Upon divorce, the value of the business at the time of separation will likely be split equally between both parties.
- Individual Ownership: If one party owned the business prior to entering into the marriage, then the equal split will be calculated based on how much the business’s value increased during the marriage.
- Gifted & Inherited Businesses: If the business was acquired through an inheritance or as a gift during the course of the marriage, it may not be subject to division – unless it is tied to other marital assets (e.g. the matrimonial home).
Issues may arise when both spouses wish to continue being involved in running the business, especially when both are entitled to do so. In addition, when a business division is involved in the divorce process, hidden costs and expenses can come into play. However, every situation is different. This is why we recommend consulting with an Ontario family lawyer if you find yourself in this situation.
How Can My Divorce Affect My Business Operations in the Future?
While everyone hopes for a smooth divorce, the process of separation can become contentious. As emotions run high, one spouse may attempt to leverage the business against the other spouse or make professional choices that undermine the business itself. This may have a significant impact on your business.
In situations where the former spouses decide to continue collaborating on the business, ongoing communication is often key. It may also be useful to draft a formal agreement as to the terms of your professional partnership.
In 2026, many Ontario businesses also rely on digital records, remote teams, subscription tools, social media accounts, cloud accounting, and online payment systems. Separation can raise practical questions about passwords, access to business bank accounts, signing authority, customer data, shareholder rights, and who can make decisions during the dispute. These issues are separate from, but closely connected to, the family law valuation and equalization process.
Business owners should also consider how a separation may affect cash flow. For example, temporary support, professional fees, debt repayment, or uncertainty about a buyout can place pressure on working capital. A lawyer can help you plan the family law side of the matter while minimizing unnecessary disruption to employees, customers, suppliers, and lenders.
What Steps Can Be Taken To Minimize Financial Stress On The Business?
At Gelman & Associates, we recommend prenuptial agreements in order to minimize future financial stress, business or otherwise. A prenuptial agreement should typically include clear stipulations on how the business may be split following a divorce. Likewise, being honest about the state of your finances – both personal and business – may contribute to a clearer, more amicable, streamlined process should you need to calculate how to divide your property during a divorce.
My Spouse and I Cannot Work Together After the Separation. Can I Purchase My Spouse’s Interests in the Business?
If your former spouse agrees to sell you their interests in the business, then you can purchase their share. If you cannot come to an agreement, you may need to initiate a forced sale. In such a case, the business may be sold to the highest bidder.
A buyout can sometimes be structured through an equalization payment, a transfer of other assets, staged payments, refinancing, or a shareholders’ agreement. The right structure depends on the valuation, available liquidity, tax considerations, corporate records, and whether the other spouse is actually a shareholder or simply has a family law claim to value. This distinction matters because a spouse may be entitled to an equalization payment without automatically becoming involved in the day-to-day operations of the company.
Where a negotiated solution is possible, mediation or lawyer-assisted negotiation may help spouses resolve business and property issues with less disruption than litigation. However, obtaining independent legal advice and financial advice is important before agreeing to any transfer, release, or payment schedule.
Can You Exclude a Business and Its Assets From Your Net Family Property and Support Obligations in a Marriage Contract?
A business and its assets can be excluded from potential net family property divisions through a marriage contract or pre-nuptial agreement. Spousal and child support obligations are typically calculated based on your income, including your net income from a business (once expenses have been deducted). In a marriage contract, you may stipulate how you wish to address spousal support obligations in the future.
That said, support and property issues should be treated carefully. A domestic contract may address property division and can set expectations around business ownership, but support clauses may still be reviewed in light of the applicable legislation, disclosure, fairness, and the circumstances at the time of separation. For child support, the Federal Child Support Guidelines remain central, and courts can look beyond a business owner’s reported personal income in some circumstances. In most cases, you cannot determine the amount of child support you will pay following a separation in a prenuptial or postnuptial legal agreement.
A properly drafted agreement should include clear disclosure, realistic valuation assumptions, and specific language about retained earnings, shareholder loans, dividends, future growth, business debts, intellectual property, and any expected contributions by the non-owner spouse. Our Toronto prenuptial agreement lawyers can help business owners and their partners consider these issues before or during marriage.
I Started My Business on My Own Without My Partner. Does This Change the Division Process?
If you built your business from the ground up while you were married, and your former partner is not involved in it, then the business is yours. There will likely be no contention as to who has ownership of the business itself. However, calculations may still be made on how much your business has increased in value over the course of your marriage. This number may be used to determine the net family property that will be split equally between both spouses.
This can be frustrating for entrepreneurs who feel that they took the financial risk, worked long hours, and made all major business decisions. Ontario’s equalization system, however, generally focuses on the financial growth during the marriage, not only on whose name appears on the shares or who worked in the business. The non-owner spouse may not receive ownership or control, but the business value may still influence the equalization payment.
The records available at the date of marriage, date of separation, and current date can make a significant difference. Bank statements, corporate minute books, tax returns, payroll records, shareholder ledgers, loan documents, real estate holdings, RRSPs, investments, and business debt information may all be relevant.

How Can I Protect My Business Before and During a Divorce?
At Gelman & Associates, we recommend preparing a thorough prenuptial agreement to help protect both parties and mitigate future conflicts over business ownership or value. While it may be challenging to consider the terms of your separation when you are in the early stages of a relationship, having a marriage contract in place can help provide peace of mind.
You may be able to protect your business by including clear guidelines in your agreement as to who will retain ownership should you and your spouse separate, and how this property will be split.
Before a dispute arises, business owners should:
- Keep their personal and corporate finances separate
- Maintain accurate accounting records
- Document shareholder loans
- Preserve annual financial statements
- Avoid using corporate assets in ways that blur personal and business property
If there are other shareholders, a shareholders’ agreement should be reviewed to understand transfer restrictions, buy-sell rights, valuation mechanisms, and what happens if a shareholder separates or divorces.
During separation, avoid unusual withdrawals, asset transfers, unexplained changes to compensation, or steps that could reduce business value without a clear business reason. These decisions may create distrust, increase litigation, or affect support calculations. A family lawyer can work with accountants, valuators, and corporate advisors to help protect the business while ensuring required disclosure is provided.
We Have Decided to Split Our Business Assets. What Do We Need to Consider?
If you have decided to split your business assets, you will likely need to hire a business valuator who may calculate the value of your company by reviewing your past and projected earnings, and quantifying its securities and/or intangible assets.
You will also likely need to work with a family lawyer who is experienced with business ownership and entrepreneurship. They can help articulate how you wish to split your assets. You may also wish to consider how you would like to navigate business operations if you and your ex-spouse are joint owners of the business, especially if you disagree on who will continue to work there.
What If My Ex-Partner Was Not as Invested in The Business as I Was?
It would be very difficult to prove the full extent of an ex-partner’s investment in the business. If you and your ex were married, and there is no pre-nuptial agreement in place stating otherwise, they may be entitled to an equal share of your business or its increase in value over the course of your marriage.
The court often also recognizes that spouses contribute to a marriage in different ways. One spouse may have built the company directly, while the other contributed through childcare, household responsibilities, emotional support, administrative help, or financial stability during the business’s early years. The equalization framework generally avoids a line-by-line assessment of who contributed more to each asset.
For common law partners, the analysis can be different because unmarried spouses do not have the same automatic property equalization rights in Ontario. However, claims such as unjust enrichment or trust-based remedies may still arise in some circumstances. Anyone separating from a common law partner should seek legal advice about their specific facts.
Can the Non-Owner Spouse Contest the Business Valuation Report and Obtain Their Own Valuation?
Both spouses are entitled to contract a business valuator to conduct a report. It is therefore within a non-owner spouse’s right to contest their ex’s report, and obtain their own valuation and/or produce a critique report.
A competing valuation may challenge the assumptions, methodology, date of valuation, treatment of goodwill, normalization of income, discounts, tax assumptions, or the completeness of the records provided. In some cases, the non-owner spouse may also request further disclosure to understand whether the valuation captures all relevant business interests and related companies.
This is one reason full and organized disclosure is so important. In a business-owner divorce, relevant records may include corporate tax returns, notices of assessment, general ledgers, financial statements, shareholder agreements, loan documents, payroll records, dividends, management fees, related-party transactions, and recent appraisals of business-owned property.
What Happens if I Start a Business Before My Divorce is Finalized?
Net family property – the property that will be divided in a divorce – is restricted to property accrued and/or grown in value during the timeline of your marriage. From the moment of your separation, any wealth or debt you accumulate is your own and will not be included in the calculations of your net family property. Therefore, if you start a business after you have been separated but before your divorce is finalized, it should not be affected by your divorce.
That said, timing and documentation still matter. The date of separation should be clear, and the funds used to start the new business should be traceable. If the new company is funded with assets accumulated during the marriage, joint funds, undisclosed income, or money removed from an existing business, disputes may still arise.
A new business may also affect support if it changes your income, earning capacity, or access to corporate funds. Even where the new business is not part of your net family property, it may become relevant to future support, disclosure, or variation issues under the Divorce Act or Ontario family law.
