For most people going through a divorce, the family home is the biggest asset on the table. For a significant portion of Eastside tech professionals, it isn’t close. A single RSU grant from a company like Microsoft can represent more household wealth than the mortgage balance, the retirement accounts, and the savings combined. Most of those shares haven’t vested yet.
What many people don’t know is that Washington has a specific legal framework for handling unvested equity in divorce, and it traces directly back to a Microsoft employee. In re Marriage of Short, 125 Wn.2d 865 (1995), decided by the Washington Supreme Court, established the time-rule formula that Washington courts still apply today. How that formula works and how it interacts with the rest of a tech compensation package is the difference between a settlement that fairly accounts for your equity and one that doesn’t.
Located in Redmond Town Center, just minutes from Microsoft’s headquarters, our team at Alpine Family Law regularly works with high-net-worth clients whose compensation packages include RSU tranches, stock options, ESPP shares, and deferred compensation balances. This post walks through what you need to understand before those conversations start.
Why Tech Equity Is Harder to Divide Than Any Other Marital Asset
A bank account has a balance. A house has an appraised value. An RSU grant has neither at the moment it’s issued. Its worth depends on continued employment, a future vesting schedule, and a stock price that will be different on every vest date. That uncertainty makes equity compensation categorically harder to divide than any other asset class in a divorce.
Washington courts don’t treat unvested RSUs as speculative future benefits, though. They treat each vesting tranche as delayed compensation for work already performed. That framing matters: it means courts look backward to determine what portion of a grant was “earned” during the marriage, rather than forward to ask whether the shares will ever vest. The timing of the work, not the timing of the payout, drives the community property analysis.
Washington’s Community Property Rules and the Short Analysis
Under RCW 26.16.030, all property acquired during marriage is presumptively community property. For equity granted during the marriage but vesting after separation, or granted before the marriage and still vesting during it, the Short analysis provides the method for sorting out what belongs to the community and what belongs to the individual spouse.
The Short analysis works as a coverture fraction: a ratio comparing how much of the grant-to-vest period fell within the marriage to the total grant-to-vest period. That fraction, applied to each tranche, determines the community’s share. The rest is separate property. As a concrete example: if an RSU tranche was granted 12 months before the marriage and vests 24 months after the wedding, the total grant-to-vest period is 36 months. The 24 months inside the marriage represent two-thirds of that period, so two-thirds of that tranche is community property. The calculation runs separately for every tranche, which matters when an employee holds grants from multiple years simultaneously.
Washington applies a just and equitable division standard rather than a strict 50/50 rule. Fifty percent is the starting point, but under RCW 26.09.080, courts can deviate based on the nature and extent of community and separate property, the length of the marriage, and each spouse’s economic circumstances at the time of division. In practice, most settlements involving long marriages and high-earning tech professionals still land close to equal, but the flexibility exists and can matter in the right case.
Performance Grants vs. Retention Grants: Why the Purpose of a Grant Changes Its Classification
Not all RSUs are granted for the same reason, and that purpose affects how they’re classified. Washington courts look at why a grant was issued, not just when.
A grant tied to prior-year performance, even one that vests entirely after the date of separation, carries a strong argument that it compensates the employee for work performed during the marriage, making it community property. A grant structured primarily as a retention incentive, where the purpose is to keep the employee going forward, may have a stronger argument as separate property for the portion earned post-separation. Grant agreements and the underlying stock plan documents are the primary sources for making this distinction, and gathering them early is essential.
The job-switch scenario adds another layer. When a tech professional leaves one employer for another, unvested RSUs at the departing company are typically forfeited. New employers often compensate for that forfeiture through a signing bonus or an accelerated RSU grant. If that bonus was structured to replace forfeited community-property RSUs, a portion of it may itself be community property, even though it was received after the marriage effectively ended. This scenario is common among professionals moving between major Eastside employers and needs to be addressed explicitly in settlement negotiations.
The Full Microsoft Compensation Stack: RSUs, ESPP, & Deferred Compensation
Microsoft employees frequently hold several distinct equity-related assets at the same time, and each one has different legal and tax treatment in a divorce. Analyzing them in isolation produces an incomplete picture.
RSU Tranches From Multiple Grant Years
Most Microsoft employees accumulate grants across annual cycles, meaning they may be simultaneously vesting shares from grants issued in different years, each with its own grant date, vesting schedule, and Short calculation. A thorough property division needs to account for every open tranche, not just the most recent one.
Employee Stock Purchase Plan Shares
Microsoft’s ESPP allows employees to purchase company stock at a 10% discount, contributing up to 15% of pay or $25,000 annually, whichever is less. Shares purchased with community funds during the marriage are community property. ESPP shares transferred between spouses incident to divorce are generally tax-free under IRC section 1041, but any appreciation between the original purchase price and a future sale will be taxed as capital gains to whoever holds the shares at sale. Settlement language should address this clearly.
Nonqualified Deferred Compensation
Microsoft’s Deferred Compensation Plan is available to employees at Level 67 or higher and permits deferral of up to 75% of base salary and up to 100% of annual bonus. Unlike a 401(k), a nonqualified deferred compensation plan isn’t a funded retirement account. It’s an unsecured promise by the company to pay in the future. That distinction has two consequences for divorce: the plan balance can’t be divided using a Qualified Domestic Relations Order, the mechanism used for 401(k) accounts and pensions; and because the balance represents an unfunded liability, the non-employee spouse has no direct claim on a specific pool of assets. The community’s interest must be addressed through the settlement agreement itself, typically through an offset against other assets or a carefully structured payment obligation.
How Unvested RSUs Actually Get Divided: Three Common Structures
Once the community portion of each equity asset is identified, the parties need to decide how to divide it. Three structures are most common for unvested RSUs.
If-and-When Distribution
The employee spouse holds the non-employee spouse’s share in constructive trust (a legal arrangement where one party holds property for the benefit of another) and transfers the appropriate shares as each tranche vests. This approach tracks actual value but requires ongoing cooperation and a carefully drafted settlement agreement, including provisions for what happens if the employee spouse leaves the company before vesting.
Offset Against Other Assets
The non-employee spouse accepts other community assets of equivalent value now, in exchange for releasing any claim to unvested RSUs. This provides certainty and a clean break but requires agreement on the present value of unvested equity, which typically involves a financial professional.
Hybrid Structure
A hybrid combines an offset for a portion of the unvested shares with an if-and-when arrangement for the rest. This can work when the parties agree on the value of some tranches but not others, or when available offsetting assets cover only part of the community interest in unvested equity.
Settlement language should also address blackout periods, windows during which Microsoft restricts trading in company stock. A non-employee spouse who receives shares through a divorce transfer may be unable to sell immediately if a blackout is in effect. Cooperation clauses in the settlement agreement can help manage this, but both parties should understand the restriction before finalizing terms.
The Double-Exposure Problem: RSUs as Both Property & Income
There’s a classification question that doesn’t get enough attention in most RSU divorce discussions: the same vesting RSUs being divided as property may also be counted as income for spousal maintenance purposes under RCW 26.09.090. Washington courts have discretion to treat regularly vesting RSUs as ongoing income available for support calculations, separate from the property division analysis.
The risk is a double-exposure outcome. If RSUs are treated as divisible property and also counted as income for maintenance, the employee spouse is effectively giving up value twice on the same compensation. Avoiding that result requires precise coordination between the property division terms and the support terms, with settlement language that clearly defines how RSU income is being treated for each purpose. It’s one of the more technically demanding aspects of a high-net-worth tech divorce, and careful drafting here produces real financial consequences.
Putting It All Together
For Eastside tech professionals, the financial stakes in a divorce extend well beyond any single asset. The interaction among multiple RSU tranches, ESPP shares, a nonqualified deferred compensation balance, and the spousal maintenance calculation creates a web of decisions where each affects the others. Getting one piece right while missing another can produce a settlement that looks complete on paper but leaves significant value unaccounted for.
This kind of case benefits from both legal and financial coordination from the beginning, not as an afterthought during final negotiations.
