Introduction

Stock options are a form of compensation that gives an employee the right to purchase company stock at a set price — known as the exercise price or strike price — at some point in the future. In a divorce, stock options can represent significant value, but they also present some of the more complex disclosure and division challenges of any asset type.

Unlike a bank account with a straightforward balance, stock options may be unvested, may not yet be exercisable, or may have a value that depends on future events. Understanding how they work, how they are valued, and how courts approach their division is important in any divorce where one spouse holds stock options as part of their compensation.

What are stock options?

A stock option gives the holder the right — but not the obligation — to buy a specified number of shares of company stock at the exercise price, after a vesting period has been satisfied. Two main types appear in employee compensation packages.

  • Incentive stock options (ISOs) are typically offered to employees and carry favorable tax treatment under the Internal Revenue Code. Gains from ISOs may qualify for capital gains tax rates rather than ordinary income rates, subject to specific holding period requirements.
  • Non-qualified stock options (NSOs or NQSOs) are more broadly available and do not carry the same tax advantages as ISOs. The difference between the exercise price and the fair market value of the stock at the time of exercise is treated as ordinary income.

Both types can be subject to vesting schedules — meaning the employee must remain employed for a defined period before the options can be exercised. Options that have not yet vested are unvested; those that have satisfied the vesting requirement are vested.

Are stock options marital property?

Whether stock options are marital property — and to what extent — depends on when they were granted, when they vest, and the law of the state in which the divorce is taking place. The analysis is more complex than for most asset types because options often span periods both inside and outside the marriage.

In most states, the portion of stock options that is attributable to services performed during the marriage is treated as marital property. Options that were both granted and fully vested during the marriage are generally treated as entirely marital. Options that were granted before the marriage, vest after the separation, or span both marital and non-marital periods require apportionment — a calculation that determines what share of the option’s value is marital and what share is separate.

Courts in different states have adopted different formulas for this apportionment, and the approach can vary significantly. Legal advice specific to your state is important when stock options are involved.

How stock options are valued in divorce

Valuing stock options in a divorce involves considerations that do not apply to most other assets.

Vested options in publicly traded companies

For options in a publicly traded company that have already vested and are exercisable, the intrinsic value — the difference between the current market price of the stock and the exercise price — provides a straightforward starting point. If the current market price is above the exercise price, the option has intrinsic value. If it is below, the option is said to be underwater and has no current intrinsic value, though it may still have time value if there is potential for the stock price to rise before the option expires.

Unvested options

Unvested options present a more complex valuation challenge because their ultimate value depends on future events — whether the employee remains employed through the vesting date, and what the stock price will be at that point. Financial models — most commonly the Black-Scholes model — can be used to estimate the present value of unvested options, but these estimates involve assumptions about future stock price volatility and other factors. A financial expert with experience in this area is typically needed to produce a reliable valuation.

Options in privately held companies

Options in a private company are more difficult to value because there is no public market price for the underlying stock. Valuation typically requires a professional business valuation of the company to establish the current value of the stock, from which the option value can be derived. See our article on business valuation in divorce.

How stock options are divided in divorce

Courts and parties use several approaches to divide stock options in a divorce, depending on the circumstances and the state involved.

Immediate offset

One approach is to value the marital portion of the stock options and offset that value against other marital assets — for example, by awarding the non-employee spouse a larger share of another asset of equivalent value. This approach resolves the division at the time of the divorce without requiring ongoing interaction between the parties, but it requires a reliable valuation of the options at the time of settlement.

Deferred distribution

Another approach is to defer the division until the options are actually exercised. Under this approach, the marital portion of the options — determined by the apportionment formula — is split between the spouses at the time of exercise. This avoids the need to value unvested or uncertain options at the time of divorce but requires the parties to maintain an ongoing financial relationship until exercise occurs.

If-and-when distribution

A variation of deferred distribution, the if-and-when approach provides that the non-employee spouse receives their share of the options only if and when the employee spouse chooses to exercise them. This approach is sometimes used for unvested options where the outcome is uncertain.

Tax considerations

The tax treatment of stock options at exercise has significant implications for their after-tax value and for how they are best divided. ISOs and NSOs are taxed differently at exercise, and the timing of exercise affects what tax rates apply. In a divorce settlement involving stock options, it is important that both parties understand the tax consequences of the proposed division — not just the gross value.

A Certified Divorce Financial Analyst can model the after-tax value of different division scenarios to help ensure that the settlement is financially informed. See our article on what is a Certified Divorce Financial Analyst.

Disclosure requirements

Stock options are a required disclosure item in divorce financial disclosure. Both vested and unvested options must be listed on the financial affidavit, along with the number of options, the exercise price, the vesting schedule, and the expiration date. Employer benefit statements and equity award agreements are the primary documents that establish these details.

If you have reason to believe the other spouse holds stock options that have not been disclosed, a request for production can ask for all equity award agreements and employer benefit statements. A subpoena directed at the employer can independently verify what equity compensation has been granted. See our articles on requests for production of documents and what is a subpoena in divorce.

Frequently asked questions

Are unvested stock options marital property?

In many states, unvested stock options that were granted during the marriage are at least partially marital property — even if they have not yet vested. The analysis depends on why the options were granted: if they were compensation for services performed during the marriage, courts typically treat the corresponding portion as marital. State law varies significantly on this point and legal advice specific to your state is important.

What happens to stock options that are underwater?

An option is underwater when the exercise price is higher than the current market price of the stock — meaning exercising it would result in a loss. Underwater options have no intrinsic value at the time of the divorce but may have time value if the stock price could recover before the options expire. How underwater options are treated depends on the circumstances and what the parties agree or the court orders.

Can stock options be transferred to a spouse in a divorce?

Whether stock options can be directly transferred to a non-employee spouse depends on the terms of the equity award agreement and the company’s plan documents. Many plans restrict transferability. Where direct transfer is not permitted, deferred distribution arrangements or an offset against other assets may be used instead. The company’s plan administrator can provide information on what is permitted under the specific plan.

How do restricted stock units differ from stock options?

A restricted stock unit is a grant of company stock that vests over time — when it vests, the employee receives shares. A stock option gives the right to purchase shares at a set price. RSUs have value as long as the company’s stock has value; stock options only have intrinsic value when the stock price exceeds the exercise price. Both are forms of equity compensation that may be subject to division in a divorce, and both must be disclosed on the financial affidavit.

What formula do courts use to determine the marital portion of stock options?

Courts in different states use different formulas. A commonly used approach — sometimes called the time rule — calculates the marital portion as the fraction of the vesting period that fell within the marriage. For example, if an option vests over four years and two of those years fell within the marriage, fifty percent of the option may be treated as marital. The specific formula applied depends on state law and the facts of the case.

What documents do I need to identify and value stock options?

Key documents include equity award agreements, employer benefit statements showing all outstanding grants, vesting schedules, the company’s stock plan documents, and recent stock price information for publicly traded companies. For private company options, a business valuation may also be needed. Our Asset Inventory Worksheet provides a structured format for recording equity compensation alongside other marital assets.
