If you or your spouse works in tech, finance or any field where equity compensation is common, stock options and restricted stock units (RSUs) may be among the most valuable assets in your marriage. Yet in a divorce, they are often the most overlooked part of the marital estate. Understanding how New York courts handle them can make a significant difference in what you walk away with.
What makes stock options and RSUs marital property
New York law generally treats property acquired during the marriage as marital property subject to division. Stock options and RSUs granted while you were married fall into that category, unless the receiving spouse can show they acquired them as a gift, an inheritance or in exchange for separate property.
The complication arises because stock options and RSUs vest over time. The grant date, the vesting schedule and the date the spouse filed the divorce complaint all matter when determining what portion belongs to the marital estate.
How courts calculate the marital portion of stock options and RSUs
Courts do not treat all stock options and RSUs the same way. New York courts first determine whether the employer intended the grant to reward past services or incentivize future performance, because the answer changes how courts calculate the marital portion.
If the grant rewards past services: Courts generally treat it as entirely marital property regardless of when it vests.
If the grant is intended as a future incentive: Courts apply the time rule or coverture fraction. The formula works like this:
- Divide the number of months from the grant date to the date the divorce was filed
- By the total number of months from the grant date to the vesting date
- Apply the resulting fraction to the total shares or options to determine the marital portion
For example, if the employer granted an RSU 12 months before the spouse filed for divorce, and it takes 36 months to vest in total, courts would classify one-third as marital property and the remaining two-thirds as separate property.
If the shares have not yet vested at the time of divorce, courts typically distribute the non-employee spouse’s share on an if, as, and when basis — meaning they receive their portion when and if the shares actually vest.
What you could be leaving on the table
Stock options and RSUs can represent a significant portion of the marital estate, yet they are easy to miss or miscalculate in a divorce settlement. Misidentifying the marital portion or overlooking tax consequences can have lasting financial consequences.
Having legal guidance from a lawyer familiar with how New York courts handle these assets gives you a clearer picture of what you actually stand to receive.
