MBE Rules · Community Property

Stock Options

Hug / Nelson formulas

The rule

Unvested options are apportioned by time rule: Hug (from employment start) applies when options reward past services; Nelson (from grant) applies when they incentivize future service — the community share is the marital fraction of the vesting period.

In plain English

In community property states, stock options earned during marriage can be divided between spouses. Unvested stock options are treated differently based on whether they reward past services or incentivize future work, with the community share calculated based on the time the couple was married compared to the total time it takes for the options to vest.

Worked example

Alice and Bob were married for 5 years before Alice received unvested stock options from her employer that will vest over 10 years. Since the options are intended to reward her past service, the community share is calculated using the Hug method, resulting in a 50% share of the options for Bob. Therefore, Bob is entitled to half of the value of the options when they vest.

Memory hook

Stock options: past work means Hug, future work means Nelson!

The trap

Students often confuse the application of the Hug and Nelson rules, especially when determining whether the options reward past or future services. This can lead to incorrect calculations of the community share.

How examiners test it

Questions typically present a scenario involving unvested stock options and ask candidates to identify the correct method for apportioning the options based on the timing of the marriage and vesting period.
