Stock compensation makes up 20-40% of total pay for tech workers at Amazon, Google, and similar companies. When those employees divorce, unvested RSUs often become the most valuable—and most complicated—asset to divide.
The stakes are especially high in California and Washington. Both are community property states. Both host major tech hubs. And initial RSU grants in these regions commonly range from $50,000 to $500,000+, with senior engineers and managers pulling in annual refresh grants between $75,000 and $300,000+.
Unvested stock isn't like a savings account you can split down the middle. The shares haven't actually transferred yet. Their value changes daily. Tax consequences won't be clear until vesting. And courts have to figure out what portion was "earned" during the marriage versus before or after.
Unvested Stock and Community Property Basics
Restricted Stock Units are a promise. Your employer agrees to deliver company shares after you meet certain conditions—usually staying employed for a set period. Unlike stock options, RSUs have value even if the stock price stays flat. That makes them a significant marital asset.
Most RSU grants vest over four years. Some follow a straight 25% annual schedule. Others are front-loaded (or back-loaded) with patterns like 5-15-40-40. Until vesting happens, these shares can disappear if the employee quits or gets fired.
Community Property Fundamentals
Nine states use community property laws: Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin. The basic rule: assets acquired during marriage through either spouse's work belong equally to both.
Many people assume unvested stock is separate property because the employee hasn't "received" it yet. Wrong. Community property states treat unvested stock earned during marriage as divisible. Courts use apportionment formulas to figure out what percentage came from marital effort.
Another common mistake: thinking stock granted during marriage but vesting after divorce is 100% community property. Courts actually divide these based on marital service time versus total service time needed for vesting. Every grant gets analyzed on its own.
California law requires full disclosure of all stock compensation—including unvested grants—under Family Code Sections 2100-2113. Hide these assets and you're looking at penalties, maybe even an overturned settlement.
Why Timing Matters
Courts look at what the stock is actually compensating. Does the grant reward past performance? That's community property if earned during marriage. Does it incentivize future retention? Potentially separate property for post-separation service. Both? Then it gets apportioned.
California, Washington, and Other Community Property States
California and Washington have both developed specific methods for handling unvested stock in divorce.
California's Time Rule Formula
California uses the "time rule" formula, established through cases like Hug and Nelson. The math determines the community property share based on how much of the vesting period fell within the marriage.
Here's how it works:
- Numerator: Months from grant date (or marriage date, whichever is later) to separation date
- Denominator: Total months from grant date to vesting date
- Result: Community property percentage, split 50/50 between spouses
Say an RSU grant was awarded January 1, 2020, with 4-year vesting. The couple separated January 1, 2023. Three of the four vesting years happened during marriage. About 75% of those shares would be community property—each spouse gets 37.5% of that grant's value.
Washington's Approach
Washington uses similar time-based apportionment under Revised Code Section 26.09.080. Courts have discretion in property division but generally follow California's time-rule calculations for unvested equity.
The financial stakes in these regions are enormous. Median home prices tell the story: San Francisco Bay Area runs $1.3M to $2M+, Seattle metro $700K to $900K, Los Angeles $800K to $1.2M as of 2023. Stock grants are often how families build equity in these markets.
Other Community Property States
Texas courts examine whether unvested stock compensates past, present, or future services. Arizona follows community property principles but sometimes allows equitable division rather than strict 50/50 splits. Idaho, Louisiana, Nevada, New Mexico, and Wisconsin each apply their own variations.
Thinking about moving to a non-community property state before filing? It probably won't help. The law where you lived when the asset was earned typically controls how it's characterized.
Amazon vs. Google: Different Schedules, Different Problems
Amazon and Google structure their vesting differently, and that affects divorce calculations significantly.
| Factor | Amazon RSUs | Google RSUs |
|---|---|---|
| Standard Vesting Schedule | 5% Year 1, 15% Year 2, 40% Year 3, 40% Year 4 | 25% annually (equal vesting) |
| Vesting Frequency | Typically quarterly after initial cliff | Monthly or quarterly |
| Back-Loaded Impact | Higher value concentrated in Years 3-4 | Value distributed evenly |
| Refresh Grant Timing | Annual performance-based grants | Annual performance-based grants |
| Typical Initial Grant Range | $50,000 - $500,000+ | $50,000 - $500,000+ |
| Refresh Grant Range (Senior Levels) | $75,000 - $300,000+ | $75,000 - $300,000+ |
| Divorce Division Complexity | Higher (back-loading creates uneven values) | Lower (uniform vesting simplifies calculation) |
Amazon's 5-15-40-40 schedule creates headaches. If a couple separates during Year 2, most of the unvested value sits in Years 3 and 4. SEC filings show Amazon's 2022 median employee compensation included roughly $32,855 in base salary plus about $37,000 in stock—the company leans heavily on equity.
Refresh grants complicate things further. Each annual performance award has its own timeline and must be analyzed separately. Even grants awarded after separation might contain community property if they're compensating for work done during the marriage.
Running the Numbers
To calculate the time rule for each unvested grant, you need:
- Grant date
- Number of shares or units granted
- Vesting schedule (specific dates and percentages)
- Date of marriage
- Date of separation
- Current stock price (for valuation)
Step-by-Step Calculation Example
Scenario: Employee receives 1,000 RSUs on January 1, 2021, vesting 25% annually over four years. Marriage began January 1, 2019. Separation: July 1, 2023.
For shares vesting January 1, 2024 (the final 250 shares):
- Total service period: 36 months (January 2021 - January 2024)
- Marital service period: 30 months (January 2021 - July 2023)
- Community property fraction: 30/36 = 83.3%
- Community shares: 250 × 83.3% = 208 shares
- Each spouse's share: 208 ÷ 2 = 104 shares
Tax Considerations
Here's where people get tripped up: they think you just divide the pre-tax value equally. But the employee-spouse pays all the taxes at vesting—potentially 35-40%+ including state taxes in California. Settlements typically account for this through adjusted shares or gross value calculations with tax offsets.
Divorce attorneys in high-cost areas charge $15,000 to $100,000+ for complex cases involving stock. A Certified Divorce Financial Analyst runs $3,000 to $15,000 for comprehensive stock analysis. Given the amounts at stake, that expertise often pays for itself.

Frequently Asked Questions
Can unvested stock be divided if it hasn't been received yet?
Yes. Courts in community property states divide unvested stock using time-rule apportionment all the time. Division can happen through deferred distribution (shares transferred at vesting) or immediate offset (the employee keeps all shares but gives their spouse other assets of equal value).
What happens if the stock price drops significantly after divorce?
Depends on which division method you chose. Deferred distribution means both parties share gains and losses. Immediate offset at a specific valuation date means the employee-spouse takes all future market risk. Courts can't predict stock prices, so this choice matters.
Are stock grants awarded after separation automatically separate property?
Not always. A post-separation grant that compensates for work performed during the marriage—like a bonus reflecting marital-period performance—may still have a community property component. Each grant needs individual analysis.
How do refresh grants get treated differently from initial hire grants?
Every grant has its own timeline. A refresh grant awarded in Year 3 of marriage starts a new measurement period. You can't apply one formula across all grants—each needs calculation based on its specific grant date, vesting schedule, and relationship to the marriage timeline.
