Equalizing an incorporated medical or dental practice in an Ontario divorce requires hiring a Chartered Business Valuator (CBV). The CBV will assess tangible assets, patient lists, and goodwill, with valuation reports typically costing between $5,000 and $15,000 CAD depending on the clinic’s complexity.
Divorcing as a high-net-worth professional introduces a complex layer of financial scrutiny. 🏥 For doctors, dentists, orthodontists, and specialists in Ontario, their professional practice is often their single most valuable asset. Unlike a standard salaried job, an incorporated medical practice holds significant tangible assets (like specialized x-ray machines) and intangible assets (like a dedicated patient roster and community reputation).
Whether your clinic is located in downtown Toronto, Ottawa, or London, Ontario family law requires that the value of this practice be included in your Net Family Property (NFP) for equalization. However, determining exactly what a medical practice is worth is a highly specialized process. You cannot simply rely on the corporate bank balance. In this guide, we will detail how the Superior Court of Justice approaches practice valuations as of June 2026.
Step-by-Step Process for Valuing a Professional Practice
Properly valuing a clinic requires a systematic financial investigation. 📋 Both spouses must provide full and frank financial disclosure. Here is how most law firms handle the valuation process.
Step 1: Retain a Chartered Business Valuator (CBV)
You cannot use your everyday corporate accountant to value your practice for a divorce. You must hire a Chartered Business Valuator (CBV) who has specific experience with professional medical corporations. In many amicable cases, both spouses agree to hire a single joint CBV to save money and avoid a “battle of the experts.”
The CBV will act as a neutral third party. 🔍 Their primary goal is to determine the Fair Market Value (FMV) of the practice on your specific Date of Separation, which is the exact legal date the marital partnership ended.
Step 2: Provide Extensive Financial Disclosure
The CBV will require years of documentation to understand the practice’s cash flow. You must provide corporate tax returns (T2s), Canada Revenue Agency (CRA) notices of assessment, detailed income statements, and balance sheets for the last 3 to 5 years.
Additionally, they will look at the salaries paid to you, your spouse (if they were an employee or shareholder), and other staff. 💰 Often, professionals pay themselves a lower salary to leave money in the corporation for tax purposes. The CBV will “normalize” this income to reflect what it would actually cost to hire a replacement physician.
Step 3: Differentiate Between Commercial and Personal Goodwill
This is often the most contested part of the valuation. Goodwill represents the value of the practice above its physical assets. Commercial goodwill is tied to the clinic itself (e.g., a great location, a recognizable clinic name, a long-term patient list). This is fully shareable in the divorce.
However, personal goodwill is tied exclusively to the individual practitioner’s skills and personal reputation. 👤 If patients only come because of Dr. Smith, and would leave if Dr. Smith left, that value cannot be easily sold or transferred. Ontario courts generally exclude purely personal goodwill from the equalization calculation.
Step 4: Factor in Corporate Tax Liabilities (Contingent Taxes)
A professional corporation is not a tax-free piggy bank. If you were to sell the practice or withdraw the retained earnings to pay your ex-spouse their equalization payment, you would face massive capital gains or dividend taxes from the CRA.
Your CBV will calculate these “contingent tax liabilities” and deduct them from the overall value of the practice. 📝 This ensures you are sharing the true after-tax value of the business, rather than an inflated pre-tax number.
Step 5: Complete Form 13.1 and Negotiate
Once the CBV report is finalized, your lawyer will input the final value into your Form 13.1 (Financial Statement). With an objective, professional valuation in hand, most couples can negotiate a final Separation Agreement through mediation or collaborative law.
If your spouse completely disagrees with the joint valuation, they may hire their own “shadow expert” to challenge it, which inevitably leads to litigation in the Superior Court of Justice.
How Much Does it Cost in Ontario?
Valuing a professional practice is an expensive but entirely necessary investment to protect your lifelong work. 💵 Here is a breakdown of the standard costs:
- CBV Valuation Report: A comprehensive valuation for a standard dental or medical practice usually costs between $5,000 and $15,000 CAD. Highly complex, multi-partner clinics can exceed $25,000 CAD.
- Law Firm Retainers: Family lawyers dealing with high-net-worth property division typically charge hourly rates between $450 and $850 CAD, requiring initial retainers of $10,000 to $20,000 CAD.
- Court Filing Fees: If the matter requires litigation, filing an Application at the Superior Court of Justice costs $214 CAD.
- Tax Consultations: You may also need a specialized tax lawyer to structure the corporate buyout, costing an additional $2,000 to $5,000 CAD.
| Asset Type | Examples in a Practice | Inclusion in Net Family Property? |
|---|---|---|
| Tangible Assets | X-ray machines, dental chairs, real estate | Yes (at Fair Market Value) |
| Commercial Goodwill | Patient lists, clinic brand, location | Yes (Highly valuable) |
| Personal Goodwill | Individual surgical skill, personal reputation | No (Generally excluded by courts) |
How Long Does the Process Take?
Rushing a corporate valuation usually results in expensive mathematical errors. ⏱ Gathering all the necessary corporate tax documents and completing the CBV intake forms generally takes 1 to 2 months.
Once the CBV has all the data, drafting and finalizing the valuation report takes another 6 to 12 weeks. If the divorce requires a full trial because the spouses cannot agree on the valuation, navigating the Superior Court of Justice backlog can take 1.5 to 3 years.
Frequently Asked Questions (FAQ)
Can my spouse take ownership of half my medical practice?
No. In Ontario, only licensed professionals (like members of the CPSO or RCDSO) can hold voting shares in a Professional Medical Corporation. Your spouse cannot take over your clinic or patient list. Instead, the value of the practice is factored into your Net Family Property (NFP) calculation, which is equalized alongside your other marital assets and debts.
What if I started the practice before we got married?
If you owned the practice on the date of marriage, you get a “date of marriage deduction.” The CBV will value the practice on the day you married, and value it again on the day you separated. The growth in the practice’s value during the marriage is what enters your Net Family Property calculation, rather than its entire baseline value.
Does the practice value affect my spousal support obligations?
Yes, but indirectly. Ontario courts try to avoid “double dipping.” If your spouse receives a massive equalization payment based on the retained earnings of your corporation, the court must carefully consider whether it is fair to also use that same corporate income to calculate your ongoing spousal support obligations.
What happens if my spouse thinks I am hiding cash income?
If a spouse alleges that a doctor or dentist is hiding “under-the-table” income, they can request an order from the Superior Court of Justice for a forensic audit. The CBV will meticulously review lifestyle expenses and bank deposits to see if they align with the declared corporate income.
