RSUs Granted Before Marriage: Understanding Your Separate Property Entitlement

If you held stock grants before marriage in a community property state, and any of those grants vested during the marriage, the apportionment methodology that California courts apply may assign you a separate property entitlement on those vested shares. This is true even in long marriages where most of the grant's vesting happened in-marriage. Whether the entitlement translates into recoverable value depends on what happened to the shares between vesting and the date of separation and local legal practices in your area, so please consult your personal attorney.

This article walks through what the methodology produces, what the resulting entitlement looks like in numbers, and what factors affect whether it can be recovered. It is educational, not legal advice; the goal is to help a reader in this situation understand the mechanics well enough to ask informed questions of their own attorney. It is also worth noting that I do not believe this is currently common practice given the lack of existing articles on the subject at the time of this article's writing. I expect this is due to a lack of awareness, which is what this article aims to provide.

The scenario

When RSUs are granted before the marriage but some of the tranches vest during the marriage, California (and other community-property states that follow the same rule, including Washington, Texas, and Arizona) apportion the shares between separate and community property. Unvested RSUs at the date of marriage are partly the employee's separate property and partly community; the exact split depends on which apportionment method the court applies.

The example uses a 4-year grant of 480 shares vesting quarterly, with the marriage starting about 28 months into the grant and ending 18 months later. The marriage is short by California standards, but it sits in the late, steeper stretch of the grant's accrual: every in-marriage tranche has most of its grant-to-vest window sitting in pre-marriage time, so Nelson carves most of each one into SP.

The same carve-out arises in any marriage where a pre-marital grant vested in-marriage.

The geometry: curves reset at the marriage axis

When the marriage starts after the grant, every method's CP allocation curve starts at zero on the marriage date. This is because the community did not exist before the date of marriage, making it impossible for the community to have earned any shares. Since each methodology represents an earning curve vs time, this results in the curves being shifted downwards but maintaining their existing shape.

The only exception to this is the yellow curve, as this curve represents the actual vested shares delivered to the employee, while all of the other curves are different methodologies that represent how the shares are earned. Determining the right type of curve to use is a legal issue that requires analysis of employer intent.

For this article we focus on 2 methodologies:

• Vest-level Nelson, represented by the red curve, treats each vest as a separate entity that is earned linearly from the start of the grant through the date of vesting. When these calculations are added together, they form the red curve seen here. This is the default method in California and is used in similar form in other community-property states including Washington, Arizona, and Texas, sometimes under different names.
• Vested shares, represented as the blue curve, which assumes the employee only earns shares as they vest.

While the vest-level Nelson is used, the concept of this article is true for any methodology that treats portions of a future vest as already earned at the time of an earlier vest in the same grant.

The light purple shading between the two curves, from the marriage date through the date of separation, marks the region this article exists to highlight: the gap between what the community would receive under Vested Shares and what it actually receives under Vest-Level Nelson, sitting on the in-marriage portion of the timeline.

The darker purple vertical bar at DOS is the legally meaningful measurement: the height of the gap between the two curves at the date of separation. That height, in shares, is the size of the separate-property carve-out the methodology has assigned across all in-marriage vesting events.

The numbers: Vested Shares vs. Vest-Level Nelson

The above example shows a hypothetical grant of 480 shares vesting quarterly over 48 months. The simulated time of the marriage to separation is 18 months. The table below shows the number of shares for both community property (CP) and separate property (SP) for each methodology out of the total 180 shares that vested during the 18-month period under analysis.

As you can see in the case of the Vest-Level Nelson, the majority of the shares are actually separate property, not community property. In this case, these shares would be the subject of the separate property claim of the employee. No such claim arises under the Vested Shares methodology, which treats all in-marriage vested shares as community property.

Front-loaded earning methods, the default of many community-property states, favor the community less here

Most California RSU cases apply some form of the Nelson formula; it's the method courts default to for grants treated as future-service incentives. When a couple is married before the grant date but separates before the grant is fully vested, Vest-Level Nelson gives the community more shares than Vested Shares does, because it picks up partial credit for vesting events that haven't yet vested at the date of separation.

When the marriage starts mid-grant, that relationship inverts. Under Vest-Level Nelson, work performed early in a grant period is treated as earning shares at a higher rate than work performed later in the same grant period. The higher-rate early work falls in the pre-marriage period and gets characterized as separate property, while the lower-rate later work falls in-marriage as community property. The result is that Nelson reports a smaller community share than Vested Shares does in this scenario.

As noted earlier, the same pattern applies to any other apportionment methods that treat portions of a future vest as already earned at the time of an earlier vest in the same grant.

What affects whether the entitlement can be recovered

The separate property entitlement exists when the shares vest. Whether it translates into recoverable value at divorce depends on what happened to those specific shares between the vest date and the date of separation. As I am not a lawyer, I recommend discussing this with your lawyer.

A factor worth understanding: liquidation order

One thing worth being aware of: which specific shares were sold during the marriage, versus held, affects what the methodology's carve-out attaches to at divorce. An earner who held pre-marital grants through to separation has a different situation than an earner who sold pre-marital grants during the marriage and held later grants instead, even if the total dollar values and household finances were otherwise similar.

This is a structural feature of how the tracing rule interacts with identifiable assets. Decisions about which shares to sell during marriage are usually made for reasons unrelated to divorce, like tax planning, concentration management, or household cash needs. Those decisions nonetheless affect what's recoverable later. A reader who learns about this entitlement after the fact may want to gather records of their liquidation history early in any divorce discussion, since the records most relevant to recovery are often the hardest to reconstruct years later.

This also creates a vulnerability where both spouses are earners: one could liquidate the other's equity to commingle funds while preserving their own separate property claim, making education more important.

Conclusion

In community property states, you may be entitled to separate property reimbursements if you were married after the date of grant, regardless of whether the date of separation was before or after the end of the grant.
