If you work at a fast-growing artificial intelligence (AI) or technology company like Anthropic, OpenAI, or another startup preparing for a potential initial public offering (IPO); your equity may soon be worth far more than it is today. That's exciting. For employees at technology and artificial intelligence companies, equity compensation can represent a substantial portion of their financial future. Stock options, RSUs, and founder shares that have relatively modest values today could become worth millions following an initial public offering (IPO), acquisition, or other liquidity event.
But what happens to that equity when you get married?
California is a community property state, and the rules governing equity compensation can be surprisingly complicated. Depending on when your equity was granted, why it was awarded, when it vests, and whether you continue working during marriage, your spouse could acquire a community property interest in equity you originally received before the wedding. A properly drafted California prenuptial agreement can help you protect your stock options, RSUs, founder shares, and future equity appreciation while establishing clear expectations before marriage.
Understanding these issues before your company goes public can help prevent expensive property disputes later.
Are Stock Options and RSUs Community Property in California?
Yes. Stock options and RSUs may be classified as community property, separate property, or a combination of both under California law. The classification depends on the circumstances surrounding the equity award, including the period of employment it was intended to compensate.
California generally recognizes two categories of marital property:
Separate Property: Property owned before marriage, together with certain gifts and inheritances received during marriage, and the rents, issues, and profits of separate property.
Community Property: Property acquired by either spouse during marriage while domiciled in California, subject to statutory exceptions.
Under California's community property laws, earnings attributable to work performed during marriage are generally community property. This principle also applies to equity compensation, including stock options and RSUs. However, unlike a regular paycheck, equity compensation often involves a substantial delay between the date it is granted and the date it vests or becomes available for sale.
That delay creates an important legal question: If you receive stock options before marriage but they vest during marriage, who owns them?
The answer may surprise you.
What Happens to Stock Options Granted Before Marriage but Vested During Marriage?
Receiving stock options or RSUs before your wedding does not necessarily mean they will remain entirely your separate property. California courts recognize that equity compensation may reward past services, incentivize future employment, or serve both purposes. Consequently, an equity award granted before marriage but vesting during marriage may have both separate property and community property components.
California's Hug and Nelson Rules for Stock Options
Two California appellate decisions provide important guidance on how courts divide stock options between spouses.
1. In re Marriage of Hug (1984) 154 Cal.App.3d 780
In Hug, the court approved a formula that considered the employee's total period of employment through the date the options became exercisable.
This approach may be appropriate when stock options are intended, at least in part, to compensate an employee for past services.
2. In re Marriage of Nelson (1986) 177 Cal.App.3d 150
In Nelson, the court approved a different formula that measured the relevant employment period beginning on the date the stock options were granted.
This approach may be more appropriate when the equity award is primarily intended to incentivize future employment.
Importantly, neither decision established a mandatory formula applicable to every equity award. California courts examine the purpose of the compensation and the surrounding circumstances to determine an appropriate allocation.
Example: RSUs Granted Before Marriage
Suppose you work for a privately held AI company and receive 40,000 RSUs two years before your wedding. Your RSUs vest over four years, meaning that a portion of your equity will vest after you marry. Five years later, your company goes public, and your shares are worth $2 million. You might assume that because you received the original grant before marriage, the entire $2 million belongs to you.
That assumption could be incorrect.
Depending on the circumstances, your spouse may have a community property interest in the portion of the equity attributable to employment services performed during marriage. The exact allocation depends on the purpose of the grant, applicable vesting terms, relevant dates, and other evidence.
A properly drafted prenuptial agreement can address this uncertainty by expressly defining how equity granted before marriage will be characterized, including shares that vest, are exercised, or become liquid during marriage.
Can a Prenup Protect RSUs and Stock Options in California?
Yes. A California prenuptial agreement can establish how stock options, RSUs, and other equity compensation will be treated during marriage and upon divorce, subject to applicable enforceability requirements.
Without a prenuptial agreement, the parties may need to rely on California's default community property rules and potentially litigate the characterization of equity compensation. A carefully drafted agreement can instead establish specific rules governing:
Premarital equity: Whether stock options, RSUs, and shares granted or acquired before marriage remain separate property, including awards that vest or become exercisable during marriage.
Future equity grants: Whether stock options and RSUs awarded during marriage will be treated as community property or separate property.
Appreciation: Whether increases in the value of separately owned shares will remain separate property.
IPO and acquisition proceeds: How proceeds from the sale, merger, acquisition, or other disposition of equity will be characterized.
Dividends and distributions: Whether income generated by equity holdings will remain separate property or become community property.
Reinvestments: Whether proceeds used to purchase additional securities or other investments will retain their separate property characterization.
The agreement should also address what happens when equity is exchanged, converted, substituted, or replaced during a corporate restructuring or liquidity event. For employees receiving substantial equity compensation, these provisions can be among the most financially significant terms of a prenuptial agreement.
Do Startup Founders Need a Prenuptial Agreement?
Startup founders face additional considerations because their ownership interests may represent both an existing asset and the product of years of future work.
Suppose you founded a technology company before marriage and own 30% of its outstanding shares. At the time of your wedding, your ownership interest is valued at $500,000. Several years later, your company is acquired, and your ownership interest is worth $10 million. Does your spouse automatically receive half of the $10 million?
Not necessarily. However, the community may have a claim to a portion of the increased value if your personal efforts during marriage contributed to the company's growth.
Under California law, when a spouse operates or substantially contributes personal services to a separately owned business during marriage, courts may apply principles established in Pereira v. Pereira (1909) 156 Cal. 1 and Van Camp v. Van Camp (1921) 53 Cal.App. 17. These approaches generally seek to distinguish the return attributable to a spouse's separate capital investment from the value attributable to marital labor. The appropriate method depends on the circumstances.
For founders, the potential dispute may involve far more than the original value of their shares. It can extend to the company's appreciation, retained earnings, compensation arrangements, and proceeds from a future sale.
How a Founder Prenup Can Help
A founder-focused prenuptial agreement can expressly address ownership of the business and its future economic benefits.
For example, the agreement may establish that the founder's ownership interest, appreciation, proceeds, and replacement equity remain separate property, while compensation actually paid for services during marriage is treated as community property. This distinction can allow the parties to preserve the founder's ownership while sharing employment earnings during marriage.
The key is to define these rights before the company's value increases substantially, rather than leaving them for a court to determine years later.
What Happens to Separate Property Stock After an IPO?
An IPO does not automatically convert separate property stock into community property. If shares are properly characterized as separate property, a subsequent increase in their market value or their sale does not, by itself, change that characterization. However, complications can arise when IPO proceeds are mixed with marital funds or used to acquire jointly owned assets.
For example, consider the following situations:
Scenario 1: You sell separate property shares and retain the proceeds in an individual brokerage account.
The proceeds may retain their separate property characterization if they are traceable to the original separate property shares.
Scenario 2: You deposit $1 million in IPO proceeds into a joint bank account.
The legal characterization may become more complicated. Joint account ownership, the parties' intentions, applicable presumptions, and any valid written transmutation agreement may affect the outcome.
Scenario 3: You use IPO proceeds as a down payment on a home titled in both spouses' names.
California's community property and reimbursement rules may apply, including potential reimbursement rights under Family Code § 2640, depending on how the property is acquired and the parties' agreements.
Scenario 4: You sell separate property shares and reinvest the proceeds.
The replacement investments may remain separate property if the proceeds are properly traced and no valid transaction changes their characterization.
A well-drafted prenuptial agreement can establish clear rules for these situations, reducing the risk of disputes over tracing, reimbursement, and property ownership.
Should You Sign a Prenup Before Your Company Goes Public?
If you are planning to marry and hold substantial pre-IPO equity, preparing a prenuptial agreement before the IPO or another liquidity event may offer significant advantages. Before an IPO, your equity may be subject to vesting restrictions, transfer limitations, repurchase rights, or other contractual restrictions. Once the company becomes publicly traded, your holdings may experience substantial changes in value.
An agreement prepared before a liquidity event can address how those changes will be treated without requiring the parties to negotiate ownership rights after a major increase in wealth. It also provides an opportunity to document the existing equity, applicable restrictions, and available valuation information.
What About the IPO Lockup Period?
Many IPOs include lockup agreements restricting when employees, founders, and other shareholders may sell their shares. These restrictions often last approximately 180 days, although the actual period varies and some IPOs have different arrangements.
A lockup period can provide additional time to organize financial records and consider the treatment of equity proceeds. However, an IPO lockup period does not extend California's legal deadlines for entering into a prenuptial agreement. A prenup must be executed before marriage. If you are already married, the appropriate agreement would generally be a postnuptial agreement.
Can You Get a Postnuptial Agreement After an IPO?
Yes. If you are already married, a California postnuptial agreement may address the characterization of stock options, RSUs, founder shares, and proceeds from an IPO or acquisition. However, postnuptial agreements are subject to different legal considerations than prenuptial agreements.
Under California Family Code § 721, spouses owe fiduciary duties to one another, including obligations of good faith and fair dealing. Transactions between spouses that advantage one spouse may be subject to a presumption of undue influence. As a result, postnuptial agreements require particular care regarding disclosure, voluntariness, and the fairness of the transaction.
For example, if one spouse holds millions of dollars in equity that may already be partially community property, a postnuptial agreement attempting to characterize the entire holding as separate property raises different concerns than a prenup signed before the marriage. The parties should understand the existing property rights they may be modifying.
If you are engaged, it is generally preferable to address equity ownership through a prenuptial agreement rather than waiting until after marriage.
What Should Tech Employees Disclose in a California Prenup?
If you hold stock options, RSUs, or startup equity, your financial disclosures should provide a meaningful picture of your holdings and their associated rights.
Depending on your compensation structure, relevant documents may include:
Stock option and RSU grant agreements
Equity incentive plan documents
Vesting schedules and grant dates
Exercised and unexercised stock options
Vested and unvested RSUs
Founder shares and restricted stock agreements
Available capitalization and ownership information
Available company valuations, including relevant 409A valuations
Exercise prices and applicable restrictions
Brokerage statements and existing shareholdings
Other assets, liabilities, and financial obligations
A 409A valuation, where available, may provide relevant information, but it does not necessarily establish the fair market value of every equity interest or predict its eventual IPO value.
The objective is to provide appropriate financial disclosure and clearly identify the property addressed by the agreement.
Frequently Asked Questions About California Prenups and Stock Options
Can my spouse get half of my stock options if we divorce in California?
Potentially. Stock options attributable to employment services performed during marriage may be community property and subject to division. Options granted before marriage may also have a community property component if they compensate for services during marriage. A valid prenuptial agreement can establish a different characterization.
Are RSUs granted before marriage considered separate property?
Not automatically. Although the grant occurred before marriage, RSUs that vest during marriage may be partially community property depending on the purpose of the award and the services it compensates. A California prenup can expressly address how premarital RSUs will be characterized.
Can a prenup protect future stock options and RSUs?
Yes. A prenuptial agreement can address equity compensation awarded during marriage, including future stock options, RSUs, restricted shares, and other incentive compensation. The agreement should clearly define how these awards, their vesting, and their proceeds will be treated.
Does my spouse own half of my startup if I founded it before marriage?
Not automatically. A business founded before marriage is generally separate property. However, the community may have a claim arising from a spouse's labor and contributions during marriage. A properly drafted prenuptial agreement can address business ownership, appreciation, compensation, and proceeds.
Does an IPO turn my separate property shares into community property?
No. An IPO alone does not change the legal characterization of separate property shares. However, the treatment of equity compensation, marital labor, commingled proceeds, and subsequent transactions may create community property issues.
Can I protect my pre-IPO shares without a prenup?
California law already recognizes separate property rights in assets acquired before marriage. However, without a prenuptial agreement, disputes may arise concerning equity vesting, marital contributions, appreciation, and the characterization of proceeds. A prenup can provide greater certainty.
