Stock Options and RSU Division in a Yukon Divorce
Why Stock-Based Compensation Complicates Property Division
Stock options and restricted stock units (RSUs) granted during a marriage are family assets under the Yukon Family Property and Support Act (FPSA). They get divided the same way as pensions, RRSPs, and other financial assets — subject to the presumptive 50/50 split. The complication is that unlike a bank account with a clear cash balance, stock-based compensation often has no fixed value at the time of separation.
An unexercised stock option gives the holder the right to buy company shares at a set price (the strike price) sometime in the future. If the current market price is above the strike price, the option has "intrinsic value" — but that value fluctuates daily. If the option hasn't vested yet, the holder can't exercise it at all until the vesting conditions are met. RSUs are simpler in structure (they convert into shares upon vesting without requiring a purchase), but they raise the same timing and valuation challenges.
This creates a real problem during divorce negotiations. One spouse holds equity compensation that may be worth a substantial amount — or may expire worthless — and both sides need to agree on how to split something that doesn't have a fixed dollar value yet.
The Two Division Methods
Canadian courts, including Yukon's Supreme Court, generally use one of two approaches to divide stock-based compensation in divorce:
The Valuation Method (Clean Break)
Under this approach, a financial expert calculates the current fair market value of all vested and unvested options or RSUs using an accepted pricing model — most commonly the Black-Scholes model for options, or the current market price for RSUs that are close to vesting. The calculated value is then treated as a lump sum within the family property pool, and the non-employee spouse receives their equalization share through an offset against other assets.
For example: if the employee spouse holds stock options valued at CAD 60,000 and the couple also has CAD 200,000 in home equity, the total family asset pool is CAD 260,000. Equal division means each spouse is entitled to CAD 130,000. The employee spouse keeps the options (CAD 60,000), and the remaining CAD 200,000 in home equity is divided so that the non-employee spouse receives CAD 130,000 of it.
Advantages: This creates a clean break. Neither spouse has a financial tie to the other's future employment or stock performance. Both parties can move forward independently.
Risks: The valuation is based on assumptions. Black-Scholes relies on projected volatility, time to expiry, and interest rates — all of which are estimates. If the stock price drops significantly after the valuation date, the employee spouse overpaid. If the stock surges, the non-employee spouse got shortchanged.
The "If and When" Approach (Deferred Division)
Under this approach, no present value is calculated. Instead, the parties agree (or the court orders) that the non-employee spouse will receive a set percentage of the actual proceeds when the options are eventually exercised or the RSUs vest and are sold. The employee spouse exercises or sells when they choose, and the non-employee spouse gets their share of the net profit at that point.
Advantages: Both spouses share the upside and the downside equally. No speculative valuation is required, and neither party feels they got the worse end of a guess.
Risks: The spouses remain financially linked until all options are exercised or expire. This can take years — vesting schedules commonly run three to five years, and some options have 10-year exercise windows. It also creates trust issues: the non-employee spouse has to rely on the employee spouse to report exercises honestly and to make reasonable exercise decisions rather than letting options expire.
The Vesting Problem
Not all stock options or RSUs are divisible. Under the FPSA's family asset framework, only the portion of equity compensation that was granted during the marriage (or more precisely, during the period of cohabitation) is subject to division. Options granted before the marriage or after the separation date are the employee spouse's separate property.
For options that vest on a schedule, the parties may use a time-based "coverture fraction" to estimate the divisible portion, but the grant terms and the facts determine whether that approach applies:
Divisible portion = (months of marriage during the vesting period) ÷ (total months in the vesting period)
If an employee received a 4-year vesting stock option grant 18 months before the separation date, and the total vesting period is 48 months, an illustrative coverture fraction is 18/48, or 37.5% of each vesting tranche. The remaining 62.5% is outside that estimate; the grant terms and the facts still control the legal classification.
This calculation gets more complicated with performance-based RSUs, where vesting depends on meeting company targets rather than simply waiting out a calendar schedule. Courts typically treat performance-based equity on a case-by-case basis, considering whether the performance conditions were substantially met during the marriage.

Tax Traps to Watch
Stock option and RSU division has significant tax implications that are easy to overlook:
Stock option exercise can trigger a taxable employment benefit. For a non-CCPC, the benefit is generally included when the employee acquires the shares; for a CCPC, inclusion is generally deferred until the shares are disposed of. The employee spouse is generally the person bearing this tax liability even if they're splitting the proceeds with their ex. If the non-employee spouse receives their share based on the gross exercise proceeds rather than the after-tax amount, the employee spouse effectively pays tax on money they don't keep.
The 50% stock option deduction isn't guaranteed. Under the Income Tax Act, employees of Canadian-controlled private corporations (CCPCs) and publicly traded companies can deduct 50% of the stock option benefit from taxable income — but only if specific conditions are met (including that the exercise price was at or above fair market value when the options were granted). If the deduction doesn't apply, the full employment benefit may be taxable, so the after-tax value can be materially lower.
RSUs are generally taxed as employment income when the shares or cash are delivered at vesting. Unlike stock options, RSUs have no exercise price, and the stock-option deduction does not apply. This means the after-tax value of an RSU grant is lower than its face value, and any equalization calculation that ignores taxes will overstate the employee spouse's share.
Any settlement agreement or court order that divides stock-based compensation should specify whether the division is based on gross or net (after-tax) proceeds, and which spouse bears the tax liability on each tranche.
Getting the Division Right
For separating couples where one spouse holds stock options or RSUs, the practical steps are:
Get a complete disclosure of all grants. The employee spouse should provide grant letters, vesting schedules, and the current status (vested/unvested/exercised) of every option or RSU tranche. This is part of the mandatory financial disclosure under Yukon Supreme Court Rule 63A.
Determine the divisible portion. For each grant, assess whether a time-based coverture fraction is appropriate and, if so, calculate it using the applicable grant period.
Choose a division method. The clean-break valuation approach works well when both spouses want to separate their finances completely and when the company's stock has a liquid, observable market price. The "if and when" approach works better for private company equity (where Black-Scholes inputs are unreliable) or when neither spouse wants to absorb valuation risk.
Account for taxes. Insist on after-tax calculations. A CAD 100,000 RSU grant does not have a fixed after-tax value; it depends on the recipient's federal and territorial marginal rates and the plan's withholding and settlement mechanics.
Put it in writing. Any stock option or RSU division should be documented in the separation agreement with enough specificity that it's enforceable — including which tranches are covered, the percentage allocated to each spouse, whether the division is gross or net, and what reporting obligations the employee spouse has.
