Dividing Stock Options, RSUs, and Crypto in a California Divorce

Standard community property division is mechanical: add up the assets, subtract the debts, split 50/50. But stock options, restricted stock units, cryptocurrency, and business interests break that simplicity. They vest over time, fluctuate in value, and blur the line between community and separate property in ways that bank accounts and real estate do not.

Getting the classification and valuation wrong on these assets can cost tens or hundreds of thousands of dollars. Here is how California courts handle each one.

Stock Options

Stock options give the holder the right to buy company shares at a fixed price (the "strike price") at some future date. The community property question is whether the options were granted as compensation for past work (performed during the marriage) or as an incentive for future work (which may extend past separation).

California courts apply the "time rule" from In re Marriage of Hug (1984) to allocate stock options between community and separate interests. The formula creates a fraction:

Community share = (months of employment from grant date to separation date) / (months from grant date to vesting date)

Options that vested entirely during the marriage are 100% community property. Options granted during the marriage but vesting after separation are partially community, partially separate — and the allocation depends on whether the options were granted primarily for past services or future services.

Unvested options cannot be divided outright because the employee-spouse has not yet earned the right to exercise them. Courts typically order a "constructive trust" — the employee-spouse must notify the non-employee spouse when options vest, and the non-employee spouse can direct their community share to be exercised at that time.

The tax treatment is critical: stock option exercises trigger ordinary income tax on the spread between the strike price and the market price. Any settlement that assigns option value without accounting for this embedded tax liability overpays the non-employee spouse.

Restricted Stock Units (RSUs)

RSUs are simpler than stock options because they have no strike price — when they vest, the employee receives shares (or cash equivalent) outright. The community property analysis follows the same time-rule approach as stock options: the community's share is proportional to the ratio of marital service to total service during the vesting period.

The complication with RSUs is that vesting schedules are often multi-year (typically four years with a one-year cliff). If 1,000 RSUs were granted two years before separation with a four-year vest, half vested during the marriage (community) and half vest after separation. The post-separation RSUs are partially community (for the service performed during marriage) and partially separate.

RSUs are taxed as ordinary income at vesting. Companies withhold approximately 37% in federal and state taxes at vest. Any settlement calculation must use the after-tax value, not the gross share count.

Cryptocurrency

Crypto assets — Bitcoin, Ethereum, stablecoins, DeFi tokens — are community property if acquired or earned during the marriage. The legal classification is straightforward. The practical challenges are not.

Valuation volatility. Under Family Code Section 2552(a), assets are valued as close to the trial date as practicable. For crypto, which can swing 20% in a week, the valuation date matters enormously. Either spouse can request an alternate valuation date under Section 2552(b) with 30 days' notice.

Discovery and concealment. Cryptocurrency can be stored in self-custody wallets, decentralized exchanges, or hardware devices with no bank statement to subpoena. If you suspect your spouse holds crypto, forensic blockchain analysis firms can trace transactions from known exchange accounts (Coinbase, Kraken) to private wallets. The penalties for hiding crypto are the same as hiding any community asset — up to 100% forfeiture under Family Code Section 1101.

Tax basis tracking. Each crypto lot has its own cost basis. When dividing crypto holdings, the tax basis transfers with the asset (same as any other property transfer incident to divorce under IRC Section 1041). Make sure the settlement specifies which lots each spouse receives, not just a total dollar amount.

Small Business Interests

Dividing a business in divorce does not necessarily mean selling it or splitting ownership. California courts strongly prefer assigning the business to the owner-operator spouse and equalizing the value through other assets or an equalization payment.

The first question is classification: was the business started before or during the marriage?

Business started during the marriage — entirely community property. Both spouses own a 50% interest in the business value.

Business started before the marriage — the premarital value is separate property, but the increase in value during the marriage may be partially community. Courts use one of two formulas:

• Pereira apportionment: assigns a reasonable rate of return (typically 7-10%) on the premarital business capital as separate property appreciation. Any growth above that rate is attributed to the owner-spouse's community labor and divided equally.

• Van Camp apportionment: assigns reasonable compensation for the owner-spouse's labor during the marriage. Any growth above that reasonable salary is attributed to the capital (separate property) rather than labor.

Pereira tends to favor the non-owner spouse (more value classified as community). Van Camp tends to favor the owner-spouse. The court chooses based on whether the business grew primarily through personal effort or capital appreciation.

Business valuations typically require a forensic accountant and cost $3,000 to $15,000 depending on complexity. For businesses with annual revenue under $500,000, a simpler capitalization-of-earnings approach may suffice.

Protecting Yourself With Complex Assets

Document everything. Print brokerage statements, screenshot crypto exchange accounts, save RSU vesting schedules, and photograph business financial records. California's Automatic Temporary Restraining Orders (ATROs) prohibit either spouse from transferring, selling, or hiding assets after the petition is filed — violations carry severe sanctions.
