For many executives, the largest asset in the marriage is not the house in River Oaks or the brokerage account. It is a stack of stock option grants that have not vested yet. Those options may be worth a great deal or nothing at all, and Texas law has a specific formula for deciding how much of them belongs to the marriage.

If you or your spouse holds unvested options from an energy company in the Energy Corridor, a medical or technology employer near Sugar Land, a public company in The Woodlands, or a pre-IPO startup, the way those grants are characterized, valued and divided can move a settlement by a wide margin. This guide explains how Texas handles unvested stock options in divorce and what executives and their spouses in Houston, Katy, Fulshear, Cypress and the rest of the greater Houston area should do before negotiations begin.

Why unvested stock options are different from other marital assets

A stock option is the right to buy company stock at a fixed exercise (strike) price. An unvested option cannot be exercised yet. The holder usually has to stay employed until a vesting date, and if employment ends first, unvested options are typically forfeited under the terms of the plan.

That creates four problems that cash, real estate and vested stock do not have:

• Ownership turns on time. Part of the option may reflect work done during the marriage and part may reflect work the employee will do after the divorce.
• Value is uncertain. An option is only worth something if the stock price rises above the exercise price. Options that are in the money today can be underwater next year.
• Forfeiture risk is real. A layoff, resignation or termination for cause can wipe out unvested grants.
• Taxes depend on the option type. Incentive stock options (ISOs) and nonqualified stock options (NSOs) are taxed very differently, and dividing them can change that treatment.

Unvested options rarely appear alone. Most executive packages also include restricted stock units and performance shares, an employee stock purchase plan, and sometimes deferred compensation. Our comprehensive guide to executive compensation in high net worth divorce explains how these pieces fit together.

How Texas decides what part of an unvested option is community property

Texas is a community property state. Property acquired during the marriage is presumed to be community property, and a spouse who claims separate property must prove it by clear and convincing evidence (Texas Family Code sections 3.002 and 3.003).

For stock options and restricted stock, the Legislature did not leave the allocation to case law. Texas Family Code section 3.007(d) sets out a time based formula for any employer provided option or restricted stock that requires continued employment before it can be exercised. Lawyers often call this a “time rule.” It is different from the formulas used in California and other states, so out of state articles can be misleading for Texas spouses.

The statute measures the employee’s separate property share. Whatever is left is community property.

Options granted during the marriage that vest after the divorce. The separate property fraction is:

• Numerator: the period from the date of divorce until the vesting date
• Denominator: the period from the grant date until the vesting date

Options granted before the marriage that vest during or after the marriage. The separate property fraction is:

• Numerator: the period from the grant date until the date of marriage, plus (if the option also vests after the divorce) the period from the date of divorce until the vesting date
• Denominator: the period from the grant date until the vesting date

Two details matter in practice. First, the statute uses the date the marriage is dissolved, not the date the spouses separated. Texas has no legal separation, so the community estate keeps running until the divorce is granted. Second, under section 3.007(e), the calculation is done separately for each tranche that vests on a different date. A four year grant that vests 25% per year is four calculations, not one.

We walk through the formula in more depth in The Time Rule: Dividing Stock Options Acquired During Marriage.

Worked example: a four year grant with annual vesting

The figures below are hypothetical and are used only to show the arithmetic.

An executive receives 4,000 options on January 1, 2024. They vest 1,000 per year on January 1 of 2025, 2026, 2027 and 2028. The divorce is granted on July 1, 2026.

Tranche	Vesting date	Separate property share	Community property share
1,000 options	Jan 1, 2025 (before divorce)	0%	100%
1,000 options	Jan 1, 2026 (before divorce)	0%	100%
1,000 options	Jan 1, 2027	0.5 years ÷ 3 years = 16.7%	83.3%
1,000 options	Jan 1, 2028	1.5 years ÷ 4 years = 37.5%	62.5%

The community portion is then divided by the court in a manner it considers “just and right” under Texas Family Code section 7.001. That division is not automatically 50/50. Courts can weigh factors such as each spouse’s earning capacity, the size of each separate estate and fault in the breakup of the marriage.

Four ways to divide unvested options in a Texas divorce

1. Deferred distribution (“if, as and when”). The decree awards the non-employee spouse a percentage of the community portion of each grant, payable if, as and when the options vest and are exercised. Neither side has to guess at value, and both share the upside and the risk. The cost is years of financial connection with an ex-spouse, and the employee spouse controls timing. A well drafted order addresses exercise deadlines, notice, tax allocation, and what happens on termination, death or a change in control.

2. Offset or buyout. The employee keeps the options and the other spouse receives other assets of equivalent value, such as more of the home equity or investment accounts. This gives a clean break but requires a present value for an uncertain asset. If the valuation turns out to be wrong in either direction, nobody can go back and fix it.

3. Transfer of a portion of the options. Some plans allow options to be transferred to a former spouse under a divorce decree. Many do not. Plan documents control, and the company usually has to approve and administer the transfer. ISOs cannot keep their ISO status if transferred to a former spouse (see the tax section below).

4. Hybrid structures. A partial cash payment now plus a deferred share of future proceeds can balance certainty for the non-employee spouse against liquidity for the employee. Hybrids are common when a company is private or a liquidity event is expected but not certain.

Which method fits depends on how much other liquid property exists, how close the grants are to vesting, whether the company is public or pre-IPO, and whether shares will be subject to a lockup period.

Valuing unvested options

When the parties choose an offset, someone has to assign a present value. For public company options, valuation experts commonly use an option pricing model such as Black-Scholes or a binomial model. Those models take into account the stock price, exercise price, time to expiration, volatility, interest rates and dividends. Experts then debate adjustments for forfeiture risk and the fact that the option itself cannot be sold.

For private companies there is no market price. Experts look at the company’s most recent 409A valuation, recent funding rounds and the terms of preferred stock. Because those inputs can be far apart, deferred distribution is often the more defensible choice for pre-IPO equity.

Executives who changed jobs during the marriage may have unvested grants from a prior employer that were replaced or accelerated by a new one. Tracing those “make whole” awards is covered in Dividing Equity Compensation from Multiple Employers.

Tax issues that change what each spouse actually receives

A settlement that looks equal before taxes can be far from equal after taxes. Key federal rules include:

• NSOs transferred incident to divorce. Under IRS Revenue Ruling 2002-22, a transfer of vested nonqualified options to a former spouse incident to divorce is not a taxable event for the employee. The former spouse reports the income when he or she exercises. The ruling is limited in scope, so transfers of options that are still unvested deserve specific tax advice.
• ISOs lose their status when transferred. The IRS has taken the position that transferring an ISO to a spouse in a divorce disqualifies it as an ISO, so it is treated as a nonqualified option from that point.
• Gross versus net. If the employee keeps the options and pays the other spouse a share of proceeds, the decree must say whether the share is calculated before or after taxes. Without that language, the employee can end up paying tax on income that went to the former spouse.
• Texas has no state personal income tax, which simplifies modeling for Texas residents. A spouse who moves to another state after the divorce may face that state’s tax on later exercises.

Our post on the tax implications of dividing executive compensation goes further, and options can also affect support obligations.

Provisions that protect each spouse

If you are the non-employee spouse, consider asking for:

• A schedule of every grant, with grant date, exercise price, vesting dates and expiration date
• Notice within a set number of days of any exercise, termination, or company sale
• A deadline to exercise after vesting, or the right to direct exercise of your share
• Life insurance securing your interest until the options are exercised
• Clear language on who pays the tax on your share

If you are the employee spouse, focus on:

• Applying the section 3.007 fractions correctly, so post divorce work stays your separate property
• Avoiding obligations that force you to exercise at a bad time
• Making sure you are not taxed on income paid to your former spouse
• Reviewing clawback, golden parachute and employment contract terms that could change what vests

Once a Texas property division is final, a court generally cannot change it later. A court can clarify or enforce a decree, but it cannot rewrite the substantive division (Texas Family Code section 9.007). Every contingency you care about has to be addressed before the decree is signed.

Common mistakes we see in executive divorces

• Treating unvested options as worthless because they cannot be exercised yet
• Applying a single fraction to a grant that vests in tranches, contrary to section 3.007(e)
• Using the separation date instead of the divorce date in the formula
• Ignoring grants from a carried interest or partnership arrangement, which require a different analysis (see Dividing Carried Interest in Private Equity and Hedge Funds)
• Signing a decree that says “50% of the options” with no tax, notice or deadline terms

FAQ

Are unvested stock options community property in Texas? They can be, in part. Texas Family Code section 3.007(d) uses a time based fraction to separate the portion earned during the marriage from the portion tied to work before marriage or after divorce. The community portion is divided by the court.

Which date ends the community period, separation or divorce? The divorce. Section 3.007 measures from the date the marriage is dissolved. Texas does not recognize legal separation, so the community estate continues until the decree.

Will my spouse get exactly half of my unvested options? Not necessarily. A Texas court divides the community estate in a manner it finds just and right under Family Code section 7.001, which can be unequal. Separate property portions are not divided.

Can stock options be transferred to my spouse in the divorce? Only if the plan allows it. Many plans prohibit transfers. If ISOs are transferred to a spouse in a divorce, the IRS treats them as losing ISO status.

Can the division be changed if the options later become worthless or soar in value? Generally no. Texas Family Code section 9.007 bars a court from amending the substantive property division after the decree. Contingencies should be written into the decree.

Do I need a divorce lawyer who handles executive compensation? If equity awards are a meaningful part of the estate, yes. The statute, the plan documents and the tax rules all affect the outcome.
