For tech professionals, executives, and founders in Oakland and the greater Bay Area, equity compensation often represents the largest portion of household wealth. When a marriage ends, determining how to divide unvested equity that was earned during the marriage but vests after separation is one of the most financially complex questions a California divorce court can face.
Community property and the timing of equity grants
According to the California Family Code, assets earned during a marriage belong equally to both spouses. When it comes to equity, the key question is when it was granted and why.
Equity awarded as compensation for past performance during the marriage is generally treated as community property. Equity granted strictly to incentivize future performance after the date of separation may be deemed the separate property of the earning spouse. Because most tech companies structure RSUs to vest over a multi-year schedule, many grants contain both community and separate property components.
The time-rule formulas: Hug and Nelson
California courts apply two formulas to calculate the community portion of unvested equity, drawn from California Courts property division resources and established case law.
Under the Hug formula, used when equity was granted as compensation for past services, the community share equals the time from employment start to separation divided by the time from employment start to the vesting date of each tranche.
Under the Nelson formula, used when equity was granted as a retention incentive for future performance, the community share equals the time from the grant date to separation divided by the time from the grant date to each vesting date.
Choosing the right formula can significantly change the financial outcome of a property division agreement, which is why courts examine the purpose of each grant carefully.
Tax considerations and distribution strategies
Unvested RSUs cannot be transferred between spouses without triggering immediate tax consequences or potentially violating employer plan restrictions. Two approaches are commonly used in California high-asset divorces.
A constructive trust arrangement allows the employee spouse to hold the unvested equity and remit the community portion to the other spouse as each tranche vests, after applicable federal and California income tax withholding.
An offset buyout allows the spouses to agree on a present value for the unvested equity and exchange it for other community assets such as real estate, retirement accounts, or cash reserves.
Each approach has different tax implications and risk profiles that should be evaluated with both legal and financial guidance.
Getting the right support
High-asset divorces involving unvested equity require careful analysis and precise legal drafting. A poorly structured settlement can create unexpected tax burdens or disputes as future tranches vest.
