Navigating Divorce as a Dental Practice Owner: Protecting Your Assets

In Canada, married spouses are entitled to share equally in the increase in value of their respective property during the course of their marriage. This process is known as the equalization of Net Family Property (NFP). It does not mean splitting every asset in half; rather, it equalizes each spouse's net growth in wealth over the course of the marriage.

Each spouse calculates their own NFP by determining the total value of everything they owned on the date of separation, minus debts on that date. For dentists, this includes the value of their DPC shares, which is based on the value of the dental practice plus any cash in the bank account. From this separation-date net value, each spouse deducts the value of property owned on the date of marriage.

The spouse with the higher NFP must pay the other spouse half of the difference, known as the equalization payment.

The Valuation Date and Process. The first step in calculating NFP is determining the valuation date, which is the day the married couple separated with no reasonable prospect of resuming cohabitation. Once this date is established, a professional valuation of the dental practice is required. This should be prepared by a qualified business valuator with experience in dental practices.

The valuation method is typically fair market value-what a willing dentist buyer would pay for the practice from a willing dentist seller. The valuator will consider factors such as the age and location of the practice, patient base, management style, equipment, and financial statements. Debts related to the practice, such as credit card debts, lines of credit, and business expenses, are subtracted to determine the net value.

A common question among divorcing dentists is whether their license to practice dentistry is considered property that can be valued and divided. Canadian courts have consistently held that a professional license does not constitute property for the purposes of calculating net family property. A dental license is not transferable, requires the personal efforts of the dentist to be of any value in the future, and its valuation would be unfairly speculative. Therefore, while the dental practice itself is subject to equalization, the license to practice is not.

Dentists can significantly reduce their NFP and any resulting equalization payment through a domestic contract. A domestic contract is a private agreement that allows spouses to modify or bypass the typical family laws that apply on separation and divorce. These can take the form of a prenuptial agreement, a marriage contract, or a separation agreement. A properly drafted domestic contract can exclude the value of the dental practice from equalization.

For the contract to be valid and enforceable, both parties must have proper legal capacity, there must be no duress or undue influence, and full financial disclosure must be made. Both parties should also receive independent legal advice. Failure to meet these requirements can result in the contract being set aside, bringing the dental practice value back onto the table.

The situation becomes more complex when a non-dentist ex-spouse owns common (equity) shares in the DPC. Dentists often give their non-dentist spouse equity shares to multiply the use of the lifetime capital gains exemption on sale, resulting in significant tax savings. If your ex-spouse owns non-voting common shares, they will eventually need to relinquish their shares as part of the equalization process, as only married spouses of the dentist can legally own those shares.

Having a shareholders' agreement in place can be helpful in this scenario. A shareholders' agreement can include buy-sell mechanisms, such as forcing an ex-spouse to sell their shares upon separation and divorce to the DPC or the dentist shareholder. However, a shareholders' agreement does not replace a valid domestic contract or override family laws. Even after a buy-back or sale, equalization calculations still occur, and additional equalization payments may be required.

When a dentist is the sole shareholder of their DPC, the increase in value of their shares during the marriage gets included in their NFP unless properly excluded via a domestic contract. Because a dental practice carries significant economic value, a dentist may owe a substantial equalization payment despite the ex-spouse having no ownership interest in the practice. Family law does not require a dentist to sell their practice simply because they are divorcing.

However, if the dentist does not have sufficient liquid assets or borrowing capacity to fund the equalization payment, a sale to a third party may become the only practical option. The risk is not legal ownership-it's liquidity. A practice can be retained only if the equalization obligation can be satisfied without selling.

It is important to understand that the equalization of assets is different from the obligation to pay spousal support. Although there is a crossover between the income from the practice and the valuation of the practice, Canadian family law treats these as two separate rights. A dentist can be required to both pay spousal support and share the value of the practice.

Family law cares about economic fairness between spouses, regardless of the regulated nature of the dentistry profession. Timing matters. Early planning, proper corporate structuring, and valid domestic contracts can preserve a practice for the dentist. Waiting until separation is underway significantly narrows the available options.

Dentists navigating separation or divorce should obtain coordinated advice from family law and dental law counsel. The cost of early planning is almost always far less than the cost of an avoidable sale. If you are facing separation or divorce and are concerned about your dental practice, speak with advisors who understand both family law and dental practice transactions.

In a divorce, your dental practice is considered a marital asset and its value is subject to equalization. This means the net increase in the practice's value during the marriage must be shared with your ex-spouse. While your ex-spouse cannot legally own voting shares in your Dentistry Professional Corporation (DPC), they are entitled to half of the financial growth. If you cannot afford the equalization payment using other liquid assets, you may be forced to sell the practice.

Yes, a properly drafted prenuptial agreement (or marriage contract) can protect your dental practice by excluding its value from the equalization of Net Family Property. For the agreement to be enforceable, both parties must provide full financial disclosure, enter the agreement voluntarily without duress, and receive independent legal advice before signing.

No, Canadian courts have consistently ruled that a professional license, including a dental license, is not considered property for the purposes of calculating net family property. It cannot be transferred and its future value depends entirely on your personal efforts, making it exempt from equalization.

If your non-dentist spouse owns non-voting common shares in your DPC (often done for tax planning purposes), they will need to relinquish those shares upon divorce, as only married spouses can legally hold them. A shareholders' agreement can dictate the terms of buying back these shares, but the value of the shares will still be factored into the overall equalization calculation.

Yes, it is possible to be required to do both. Equalization of assets (sharing the value of the practice) and spousal support (based on income) are treated as two separate legal rights under Canadian family law. You may have to buy out your spouse's share of the practice's value and also pay ongoing spousal support from the income the practice generates.
