Divorce and Equity Compensation: What Gets Split, and How

Henry Supinski, ChFC® · 4 min read · July 2026

Splitting a house or a 401(k) in a divorce has a well-worn process. Splitting unvested RSUs or stock options does not, and getting it wrong can leave one spouse with a tax bill the other one never sees.

Vested vs. Unvested Is the First Split

Shares that were already vested during the marriage are usually treated as marital property outright. Unvested shares are murkier: many states look at whether the grant was compensation for past service (more likely marital) or an incentive for future service (more likely separate, at least in part), and the grant date relative to the marriage timeline matters too.

A QDRO Doesn't Cover This

A Qualified Domestic Relations Order is built for splitting qualified retirement plans like a 401(k). It does not apply to RSUs or stock options. Dividing equity compensation requires specific language in the divorce settlement itself, and if that language is vague or missing, enforcing the split later can be genuinely difficult.

Valuation Timing Is a Real Fight

Company stock moves. Valuing a position as of the separation date versus the divorce filing date versus the actual vest date can produce very different numbers, especially for a volatile stock. This is worth negotiating explicitly rather than assuming it will sort itself out.

What to Get in Writing

• A clear formula for how future vests of already-granted, unvested equity will be divided.
• Who is responsible for the tax owed at vest, since RSU income is taxed to whoever holds the shares when they vest.
• What happens to equity from grants made after the separation date, which is usually treated as separate property.

Equity compensation adds a layer most divorce attorneys don't handle daily. A financial plan that accounts for the tax and cash flow reality on both sides makes the settlement language much easier to write correctly the first time.

Why You Usually Can't Just Split the Shares

Most company equity plans do not allow awards to be transferred to a former spouse. The plan document controls, and the plan document usually says no. That leaves two workable structures. In a constructive trust arrangement, the employee spouse keeps holding the awards, and when they vest and are sold, delivers the agreed share of the net proceeds to the other spouse. In an offset, the non-employee spouse takes other assets, like home equity or brokerage funds, equal to the negotiated value of the equity. Offsets are cleaner, but they require putting a value on unvested awards today, which usually means applying a discount for the risk that some of them never vest.

A Hypothetical Division

The numbers are invented. The structure is the common one. One spouse holds 4,000 unvested RSUs worth $600,000 at today's price, granted two years into the marriage and vesting over the next two years. The attorneys apply a time-based formula: for each vesting tranche, the marital share is the portion of the vesting period that overlapped the marriage. Tranches vesting soon are mostly marital. Tranches vesting further out are less so. Because the plan bars transfers, the settlement says the employee spouse will sell each tranche at vest and deliver the other spouse's share of the proceeds net of tax. Everyone knows the formula, the timing, and who bears the tax before anyone signs. That is the whole game.

How We Approach It

I spent years at SAP living with vesting schedules and grant agreements, so reading equity plans is familiar ground. When a client is heading into a divorce with equity on the table, we build a complete inventory first: every grant, its date, its vesting schedule, and what the plan document allows. Then we model what each proposed split actually delivers after tax, because a 50/50 split of shares is not a 50/50 split of money once withholding and bracket differences show up. We hand that analysis to the attorneys, who write the settlement. We don't draft legal language, and none of this is legal advice. The value is walking into the negotiation knowing what the numbers really are. And once the split is final, the spouse left holding company shares often has a concentration problem that deserves its own plan.

Questions We Hear

Are unvested RSUs marital property?

Often partly. Many states look at when the grant was made, what it was compensating, and how much of the vesting period overlapped the marriage. The usual result is a formula rather than an all-or-nothing answer. Your attorney determines how your state treats it. Our role is modeling what each formula means in actual dollars.

Can my ex-spouse just receive half the shares?

Usually not. Most equity plans prohibit transferring awards to anyone, including a former spouse. That's why settlements rely on constructive trust arrangements or asset offsets instead of direct transfers.

Who pays the tax when the shares vest?

RSU income at vest is generally taxed as compensation to the employee who earned the grant, and that doesn't change just because a settlement promises proceeds to someone else. If the settlement divides gross shares instead of net proceeds, the employee spouse can end up covering tax on money the other spouse received. Settlement language should divide after-tax value explicitly.

Do I need a QDRO for stock options or RSUs?

No. QDROs apply to qualified retirement plans like a 401(k). Equity compensation is divided through the property settlement agreement itself, which is exactly why the language there has to be precise.
