How Are Stock Options, RSUs, and Unvested Equity Divided in a Colorado Divorce?

In a Colorado divorce, equity compensation is divided grant by grant. For each award the court asks three questions: is it property or only an expectancy, how much was earned during the marriage, and what is the marital portion worth. Vested awards earned during the marriage are marital property, while awards granted for future services become marital only to the extent the services were performed before the decree.¹

The analysis is technical because the grant documents, the vesting schedule, the tax treatment, and the support calculation all interact. A number that works for property division can be wrong for support if the same shares are counted twice.

RSUs, Stock Options, PSUs, and ESPP Shares

Colorado courts look past the label to the rights each award actually gives. Restricted stock units are a promise of shares on a vesting date, while stock options are a right to buy shares at a set price for a set period. Performance share units vest only if company targets are hit, and employee stock purchase plan shares are bought with payroll deductions at a discount.

Award type	What the holder actually has	Common vesting condition	Typical division issue
Restricted stock units (RSUs)	Right to receive shares on a schedule	Continued employment through each vest date	How much of each tranche was earned during the marriage
Stock options (ISO or NSO)	Right to buy shares at a strike price	Time-based vesting, then an exercise window	Options with no current value because the strike price exceeds the share price
Performance share units (PSUs)	Shares only if targets are met	Performance period plus continued service	Whether a contingent award is property at all
ESPP shares	Shares already purchased at a discount	None once purchased	Tracing the purchase to marital payroll

Property Versus Expectancy

The starting point for property division is that property acquired during the marriage is presumed marital. The court divides the marital estate in just proportions after weighing the statutory factors.² Equity compensation complicates the first step, because an unvested award is a right that may never ripen.

The Colorado Supreme Court addressed that problem in Balanson. Options granted in consideration for future services do not become marital property until the employee performs those services, so the portion tied to work after the decree is not divided. An award that compensates past work is property when granted, even if it has not vested.

Are Unvested RSUs Marital Property in Colorado?

Partly, in most Colorado cases. The question is not whether the award has vested but when it was earned. An RSU grant made during the marriage for ongoing service is marital for the part of the service period before the decree and separate for the part after it.

Grant documents answer the earned-when question. A retention grant conditioned on three more years of employment looks forward, while a grant labeled as a bonus for a completed year looks backward. The court reads the plan and the award agreement, not the spouse’s description of them.

The Marital Portion and Time-Based Formulas

When an award is earned over time, Colorado courts commonly apportion it with a time rule, often called a coverture fraction. The numerator is the months from the grant date to the decree, and the denominator is the months from the grant date to the vest date. The fraction is applied to the shares in that tranche.

The fraction is a tool, not a statute, and the grant terms control the inputs. An award that compensates past work may be fully marital without any fraction, while a performance award may require a different approach because the contingency has not been resolved.³

Every grant agreement is evidence. Before you negotiate a split, have Johnson Law Group review the plan documents and the vesting schedule so the marital portion is calculated from the terms, not from assumptions.

Which Valuation Date Applies, and How Are Taxes Handled?

Colorado values property as of the date of the decree or the date of the property hearing if it comes first. For equity, that date fixes the share price used in a present-value offset, and it also fixes the cutoff for the time rule.

Taxes change the real value. RSUs are taxed as ordinary income when they vest, nonqualified options are taxed at exercise, and the spouse who holds the award usually carries the tax.

A division that ignores withholding hands one spouse a gross number and the other a net number. The agreement should state whether shares are divided before or after tax and who bears the tax on each tranche.

Deferred Division Versus Present-Value Offset

Colorado divorces use two ways to divide an award that cannot be transferred. A deferred division gives the nonemployee spouse a percentage of each tranche if and when it vests, with the employee spouse delivering the net shares or cash. A present-value offset assigns the award to the employee spouse at a discounted value and balances it with other assets now.

• Deferred division shares the risk: if the company falls, both spouses lose
• Present-value offset gives certainty now but requires agreeing on a discount for vesting risk and taxes
• Transfer restrictions in most plans mean the employee spouse holds the award in trust for the other under either method
• Either structure needs reporting duties: vest notices, brokerage statements, and a deadline for delivering the nonemployee spouse’s share

Can Equity Also Count as Income for Colorado Support?

Yes, and that is where double counting creeps in. Shares that vest after the decree are income to the employee spouse in the year they vest, which affects child support and spousal maintenance in Colorado. If the same tranche was already divided as property, the portion delivered to the other spouse should not be treated as the employee’s income again.

The clean approach is to decide, tranche by tranche, whether each award is being treated as property or as income, and to write that allocation into the separation agreement.

A Worked Example: A Colorado Time-Rule Split

This example is illustrative. The grant, prices, and dates are invented, and a Colorado court decides the just proportion.

Spouse A received 4,000 RSUs on January 1, 2024, vesting in one tranche on January 1, 2028, as a retention grant for future service. The decree enters on January 1, 2026. The grant-to-decree period is 24 months and the grant-to-vest period is 48 months, so the coverture fraction is 24 divided by 48, or 50 percent.

The marital portion is 2,000 RSUs. If the court divides the marital estate equally, Spouse B’s share is 1,000 RSUs, delivered as net shares or cash when the tranche vests in 2028, after tax. At a share price of $60 on the vest date, that is roughly $60,000 before tax, and less after withholding.

What this leaves out: a present-value discount if the parties choose an offset instead, and the chance the shares never vest if Spouse A leaves the company. It also leaves out the support treatment of the 2,000 RSUs that are Spouse A’s separate property.

Checklist: Grant Agreements and Transaction Records

Bring these records to your first meeting with Colorado counsel:

• Every grant notice and award agreement, including the plan document it references
• The vesting schedule for each grant, with performance conditions if any
• Brokerage statements showing vested shares, sales, and withholding
• Pay stubs and W-2s showing equity income already recognized
• Any offer letter, bonus plan, or retention agreement that explains why a grant was made

Frequently Asked Questions

Are stock options with no current value still divided?

They can be. An option whose strike price exceeds the current share price has little present value, but it is still a right that may become valuable. The agreement should address it, often through a deferred division.

What about shares I bought through an ESPP before the marriage?

Shares purchased before the marriage start as separate property. Any increase in their value during the marriage is marital under Colorado’s appreciation rule, so you need a statement showing their value on the wedding date to separate the two.
