Restricted Stock Units (RSUs) are one of the most confusing assets to divide during a divorce. Unlike a bank account or retirement fund, RSUs don’t have a fixed value today — since they haven’t vested yet.
Because of this, dividing RSUs fairly requires understanding how they work, when they become income, and how courts typically allocate them.
What Are RSUs?
RSUs are a form of compensation often provided by employers, especially in tech and corporate roles. They represent shares of company stock that vest over time, require continued employment, and fluctuate in value with the stock price. Until RSUs vest, they are considered conditional compensation, not guaranteed income.
Why RSUs Are Complicated in Divorce
RSUs are tricky because they often span both marital time (earned during the marriage) and post-divorce time (vesting after separation). This raises an important question: How much of the RSU is marital property, and how much belongs to the employee spouse alone?
The Two Most Common Division Methods
1. The Hug Formula (Time-Based Approach)
The Hug formula divides RSUs based on how much of the vesting period occurred during the marriage.
Think of it this way:
- RSUs are treated as compensation for both past work and future work.
- The marital portion is calculated based on the time between the grant date and vesting date that overlaps with the marriage.
2. The Nelson Formula (Purpose-Based Approach)
The Nelson formula focuses on why the RSUs were granted.
- If RSUs were given mainly to reward future employment or retention, more of them are considered separate property.
- The marital share is often measured based on time from the grant date to the date of separation.
Taxes Matter Too
RSUs are taxed as ordinary income when they vest, not when they are granted. Divorce agreements should clearly state who pays the taxes, how shares are transferred, and how withholding is handled.
The Bottom Line
RSUs are time-based, conditional compensation that must be divided carefully. Understanding how they vest, how courts apply division formulas, and how taxes work can help ensure a fair settlement. Working with a divorce-focused financial professional can help avoid costly mistakes.
