Key Takeaways
- In a divorce with a professional corporation in Alberta, the PC is generally family property under the Family Property Act: its value is divisible even though your spouse may be legally barred from holding its shares.
- Because most Alberta regulators restrict who can own PC shares, the non-member spouse typically receives their share of the value through equalization: other assets, a payment plan, or a buyout, not shares.
- Valuing a professional practice turns heavily on goodwill: value tied to you personally (personal goodwill) is treated differently from value that would survive a sale, and the distinction can move the number dramatically.
- The same corporation is also the income source for support, so how retained earnings, dividends, and salary are characterized affects both the property division and the support calculation.
If you are a physician, dentist, lawyer, accountant, engineer, or other professional practicing through a professional corporation in Calgary, your divorce has a layer that most separations do not. The PC is usually your largest asset, your income source, and a regulated entity all at once. This guide explains how a divorce with a professional corporation in Alberta generally works: what gets divided, who can actually hold the shares, how the practice is valued, and where the expensive mistakes happen.
Is a Professional Corporation Family Property in Alberta?
Generally, yes. Under Alberta's Family Property Act, property acquired by either spouse or adult interdependent partner during the relationship is presumptively divided equally, and that includes shares of a professional corporation and the value those shares represent. If you incorporated before the relationship began, the value of the PC at that date may be exempt, but growth in its value during the relationship is generally divisible, and proving the starting value requires documentation from the time.
The key point for professionals: the regulated status of the corporation does not shelter its value from division. What it changes is the mechanics.
Your Spouse Usually Cannot Take the Shares
Alberta professional corporations are creatures of both corporate law and the rules of the profession's regulator. For most professions, voting shares can only be held by members of the profession. Some regulators permit family members to hold non-voting shares (physicians and dentists, for example, have used family shareholding structures for income purposes), while others, such as the Law Society of Alberta for lawyers, restrict ownership to licensed members. The details vary by profession and change over time, so the specific rules of your regulator matter.
The practical consequence in a divorce is consistent: a spouse who is not a member of the profession generally cannot walk away with a piece of the PC itself. Instead, the member keeps the corporation and the other spouse receives their share of its value another way, typically through:
- An offsetting share of other family property (the house, investment accounts, RRSPs)
- An equalization payment, either lump sum or structured over time
- A combination, secured where appropriate
This is one reason a divorce with a professional corporation in Alberta is less about splitting an asset and more about valuing it correctly and then designing an overall property division around that value.
How a Professional Corporation Is Valued in Divorce
Practice valuation is usually where the real dispute lives. A chartered business valuator typically prepares the valuation, and the lawyers test it. The recurring battlegrounds:
Personal Goodwill Versus Enterprise Goodwill
Much of a professional practice's earning power can be tied to the professional personally: your reputation, your referral relationships, your hands. Value that would not transfer to a purchaser without you is personal goodwill, and how much of the practice's value is personal rather than transferable is often the single largest driver of the final number. A solo practice with no associates and no saleable patient roster is a very different valuation than a multi-professional clinic with locations and staff.
Retained Earnings and Corporate Investments
Many PCs accumulate significant retained earnings and investment portfolios inside the corporation for tax deferral. Those assets are part of the corporation's value and must be counted, net of the embedded tax that would arise on getting the money out. Ignoring that latent tax overstates the value; ignoring the assets understates it. Both mistakes are common.
Restrictions That Affect Marketability
Regulatory limits on who can buy a practice, associate buy-in structures, and clinic agreements can all affect what the shares are actually worth. A valuation that ignores them invites challenge.

The Same Corporation Also Sets Your Support Income
The PC is not only property; it is the income engine, and support is calculated from income. For professionals, guideline income is rarely just the salary you chose to pay yourself. Courts can look through the corporation under the Federal Child Support Guidelines and consider pre-tax corporate income, retained earnings, dividends, and personal expenses run through the practice when setting income for child support and spousal support.
There is also a fairness issue lawyers call double dipping: if the retained earnings were counted in the value that was divided as property, counting the same dollars again as support income can be challenged. Courts weigh this carefully, and the way your settlement characterizes corporate value and income streams can protect you, or cost you, for years. This is squarely where family law meets tax, and where generalist advice tends to run out.
Common Mistakes in Professional Corporation Divorces
Accepting the First Valuation Without Scrutiny
Valuations rest on assumptions: growth rates, capitalization rates, the personal goodwill split. Small assumption changes move six figures. The valuation should be tested, not filed.
Forgetting the Latent Tax Inside the Corporation
A dollar of retained earnings is not worth a dollar in your pocket. Settlements that equalize against pre-tax corporate value systematically overpay the other side.
Failing to Document Pre-Relationship Value
If the PC predates the relationship, the exemption for its starting value is only as good as the evidence: financial statements from that era, share registers, tax returns. Gather them early.
Restructuring After Separation Is on the Table
Changing compensation, moving assets between the PC and a holding company, or adding shareholders once separation is contemplated invites scrutiny and can undermine credibility. Get advice before touching the structure, not after.
Ignoring the Support Interaction
Negotiating the property number and the support number in isolation leaves value on the table. They are one financial picture and should be settled as one.
Frequently Asked Questions
Can my spouse take half of my professional corporation in Alberta?
Generally your spouse receives a share of the corporation's value, not the corporation itself. Regulatory rules typically prevent non-members from holding PC shares (the specifics depend on your profession's regulator), so the value is equalized through other assets or a payment rather than a transfer of shares.
Is my professional corporation exempt if I incorporated before we met?
The value of the corporation at the start of the relationship may be exempt under the Family Property Act, but the growth in value during the relationship is generally divisible. The exemption depends on being able to prove the starting value with records from that time.
How are retained earnings in my PC treated in a divorce?
Twice, potentially: they form part of the corporation's value for property division, and they can be considered when determining your income for support. How the settlement characterizes them matters, because dividing the same dollars as property and then paying support on them again can be challenged as double dipping.
Do I need a valuation of my practice, and who pays for it?
In most contested files, yes: a chartered business valuator values the practice. Spouses sometimes jointly retain one valuator to control cost, or each retains their own where the numbers or trust are contested. Payment is typically negotiated or shared, and the cost is small relative to what an untested valuation can cost you.

A divorce with a professional corporation in Alberta is a corporate, tax, and family law problem in one file.
