Stock Options, RSUs and Deferred Compensation in an Illinois Divorce

Oct 5, 2026 | Divorce

If you are an executive or married to one, stock options in an Illinois divorce can become a key issue because separation changes everything.

You may not know whether those shares will be divided, how much they are worth today, or what happens to those you have not received yet. That uncertainty can also slow down any negotiations with your former spouse.

The good news is that Illinois law has clear rules for stock options in an Illinois divorce. Understanding them allows you to negotiate based on facts rather than fear.

In this guide, the team at KHK Family Law & Divorce Attorneys explains each type of compensation, how the law treats it, and the real ways to divide it. Keep reading!

Types of Equity and Deferred Compensation

Before discussing division, it helps to understand exactly what you receive. Each type of compensation works differently, and that difference affects how a judge divides it.

Stock Options

You should know that a stock option in an Illinois divorce is the right to purchase company stock at a fixed price set on the date the option is granted.

For example, if your option allows you to buy shares for $20 and the stock is worth $50, you gain $30 per share. As you can see, that difference represents the option’s actual value.

However, if the stock falls below $20, the option loses its appeal because no one wants to pay more for something worth less. That is why its value changes constantly.

Restricted Stock Units (RSUs)

RSUs are shares that a company promises to give you over time as long as you continue working there. Unlike options, you do not pay anything for them when they are delivered.

They are usually released in stages, such as one-fourth each year over four years. If you leave before a certain date, you lose any shares that have not yet vested.

Once vested, however, RSUs become regular shares that you can sell or keep. Their value then depends on the stock’s daily market price.

Deferred Compensation and Bonuses

Deferred compensation is money you earn today but receive from your employer in the future. Many executives use it to reduce taxes or plan for retirement.

In practice, this type of compensation appears in several forms within executive compensation packages. These are the most common ones we see in Illinois divorces:

  • Annual bonuses paid months after the year in which they were earned.
  • Nonqualified deferred compensation plans for senior executives.
  • Retention bonuses paid only if the employee remains with the company.
  • Commissions or incentives paid in installments over several years.

The key rule is simple: what matters is not when the money arrives, but when it was earned. If you earned it while married, it is generally part of the marital estate.

Are Stock Options and RSUs Marital Property in Illinois?

This is the big question when dealing with stock options in an Illinois divorce. The answer depends on when you received the shares and, most importantly, what type of work your company intended to reward.

Vested and Unvested Shares

A vested share is already yours, and you can sell it whenever you want. An unvested share, on the other hand, depends on your continued employment with the company until a certain date.

Many people believe unvested shares are excluded from divorce because they do not technically own them yet. However, Illinois law (750 ILCS 5/503) says otherwise.

The law presumes stock options received after marriage and before the judgment of dissolution to be marital property, whether vested or unvested. Therefore, the grant date carries significant weight.

Was It Earned During the Marriage or for Future Work?

Even so, the presumption does not end the discussion. The judge examines whether the shares reward past, present, or future work because only the marital portion should be divided.

To answer that question, the court examines several specific factors because each equity grant has its own rules. The most important include:

  • The date the company granted the shares or options.
  • The vesting schedule and its end date.
  • The stated purpose of the grant under the plan documents.
  • Whether the shares depend on future performance goals or continued employment.

For example, options granted as a reward for a successful year recognize past work. In contrast, shares designed to retain you for another five years are tied to future employment.

How Shares That Vest After Divorce Are Divided

When shares vest after the judgment, courts often use a time-based formula. This formula measures how much of the waiting period occurred during the marriage.

Imagine RSUs that vest over four years, with three of those years occurring while you were married. In that case, three-fourths of those shares would be marital.

That marital portion is then divided between the spouses based on what the judge considers fair. Meanwhile, the portion attributable to the period after divorce remains yours.

How Equity Compensation Is Divided

Once the marital portion has been determined, the next step is deciding how to divide it. At KHK Family Law & Divorce Attorneys, we see three primary methods, each with advantages and risks.

Dividing the Shares or Options

The most direct approach is for each spouse to receive their share of the equity. That way, both benefit if the price rises, and both share the loss if it falls.

However, many plans prohibit transferring options or RSUs to another person. In those cases, the employee keeps the equity and gives the former spouse the portion that belongs to them.

This arrangement requires trust and clear rules in the judgment, such as deadlines for providing notice and making payments. That is why it is important to detail every step in writing before signing the agreement.

Exchanging Equity for Other Assets

Another common option is for the employee to keep the shares while the former spouse receives other assets of similar value. This allows each person to move forward without depending on the other.

To offset the value of the shares, couples often negotiate other assets that the other party values equally or more highly. Common options include:

  • The marital home or a larger share of its value.
  • A larger portion of savings or investment accounts.
  • A greater share of retirement funds, such as a 401(k).
  • A cash payment, either as a lump sum or in installments.

However, this method requires assigning a current value to the shares, which is difficult when the price changes. If the valuation is inaccurate, one spouse may end up losing money.

Dividing the Value When the Shares Vest

The third method waits until the shares vest and then divides the actual proceeds. This system is known as a “deferred distribution” because the division takes place later.

Its main advantage is that no one has to guess the future stock price because both spouses share the actual value on the vesting date. It also reduces disputes over valuations.

Even so, it keeps former spouses financially connected for years, which can be uncomfortable after a difficult divorce. That is why the judgment should clearly explain how each person’s share will be calculated and paid.

Valuation and Tax Challenges

Dividing equity does not end with the allocation formula. You also need to determine a fair value and account for taxes, two issues that can cost thousands of dollars.

Why Valuing Stock Options in an Illinois Divorce Is Difficult

A stock price changes every day, and an unexercised option does not have a fixed value until you exercise it. As a result, valuing it requires specialized calculations.

Financial experts therefore review several factors before assigning a value, and each one can significantly affect the result. The most important include:

  • The current stock price and exercise price.
  • The amount of time remaining before the option expires.
  • How much the stock price normally fluctuates.
  • Plan rules, such as restrictions on selling or forfeiture upon leaving the company.

For private companies, the challenge is even greater because their shares are not publicly traded. In those cases, an expert is typically needed to estimate the company’s actual value.

Taxes When Exercising and Selling

Equity compensation can create tax obligations at different times, and who pays depends on the type of equity and the agreement. Ignoring this can make an otherwise fair division unequal without anyone realizing it.

For example, RSUs are generally taxed as wages when they vest, while certain options create tax consequences when exercised. You should review this with your attorney and accountant:

  • The company vests the RSUs and delivers them to the employee.
  • The employee exercises the option, meaning they purchase the shares.
  • Either spouse sells the shares and realizes a gain.
  • A bonus or deferred compensation is paid.

That is why a well-drafted agreement should always compare after-tax values. If you want to learn more, review our article about taxes in divorce, where we explain each situation in detail.

Equity Compensation, Child Support, and Maintenance

Equity compensation is not only divided as property. It can also count as income when calculating child support and spousal support, known as maintenance in Illinois.

The Illinois child support law (750 ILCS 5/505) considers gross income from all sources. As a result, vested RSUs and bonuses are generally included as income.

The challenge arises when that income changes significantly from one year to the next. In those situations, judges may average several years of income or establish a percentage of each future payment.

It is also important to avoid counting the same money twice. If an equity award has already been divided as property, it generally should not be counted again as income for support purposes.

FAQ

Are Unvested Stock Options Marital Property in Illinois?

In principle, yes. Illinois law presumes options received during the marriage to be marital property, even if they are unvested. That presumption applies through the date of the divorce judgment.

However, the judge examines whether those options reward future work performed after the divorce. If so, a portion may remain with the employee and not be included in the marital division.

Does My Ex Have a Right to RSUs I Received After We Separated?

Often, yes. In Illinois, physical separation does not stop the clock because the marital presumption lasts until the divorce judgment, not until the date one spouse moves out.

Therefore, RSUs granted while you were still legally married are presumed to be marital property. Even so, if they reward future work, the judge may reduce the portion awarded to your former spouse.

How Is Deferred Compensation Divided in a Divorce?

First, the parties determine when the compensation was earned. If it relates to work performed during the marriage, it is considered marital property even if the company pays it months after the divorce judgment.

The parties then decide how to divide it: either split the payment when it arrives or offset it with other assets. It is also important to calculate the after-tax value to avoid unpleasant surprises.

Do Stock Options Count as Income for Child Support?

Yes, in most cases. When you exercise options or your RSUs vest, that money is generally included in the gross income the judge uses to calculate child support.

If equity compensation arrives irregularly, the judge may also establish a base amount plus an additional percentage each time you receive shares or bonuses.

What Documents Do I Need to Divide Equity Compensation?

Without complete documentation, no one knows exactly what is being divided or how much it is worth. That is why the first step is gathering all information about the company’s compensation plan:

  • The equity plan documents and each grant notice.
  • The vesting schedule for each RSU or option.
  • Brokerage or equity platform statements.
  • Tax returns and W-2 forms from recent years.

With these documents, your attorney can reconstruct the history of each equity award, from the grant date to today. This allows your attorney to establish with supporting evidence which portion is marital and which portion belongs solely to you.
