What Happens to Your Stock Options and RSUs in a California Divorce?

If you or your spouse receives equity compensation — stock options, RSUs, performance shares, or similar awards — your divorce will almost certainly involve a question that surprises most clients: when was this equity earned?

That question matters because the answer determines how much of it belongs to the community and how much belongs to the spouse who received it. In California, the answer often comes down to a formula called Nelson.

Why Equity Compensation Is Complicated in Divorce

Equity awards are not like a paycheck. They are granted at one point in time, vest over a period of time, and may be exercised or sold at yet another point in time. When a marriage begins and ends in the middle of that timeline, you can end up with an award that is part separate property, part community property, and requires a forensic accountant to sort out.

The threshold question is always: why was this award granted? The answer to that question determines which formula applies.

The Nelson Formula: Rewarding Future Service

The Nelson formula applies when an equity award is granted to incentivize future service — meaning the award is essentially a promise of ownership in exchange for work the employee has not yet done.

The formula apportions the award based on the ratio of time served during the marriage (from date of grant to date of separation) to the total vesting period (from date of grant to date of exercisability).

The math looks like this:

Community Property Shares = (Days from Grant to Separation ÷ Days from Grant to Exercisability) × Total Shares

So if an employee was granted 2,000 shares on January 1, 2022, with a vesting date of December 31, 2024, and the parties separated on December 31, 2023, the calculation would be:

• Days from grant to separation: 729

• Days from grant to exercisability: 1,095

• Community property percentage: 729 ÷ 1,095 = 66.58%

• Community property shares: 1,332 out of 2,000

The remaining 668 shares would be the separate property of the employee spouse.

When There Are Multiple Grants

In practice, most executives and tech employees receive equity grants annually, not just once. Each grant has its own date, vesting schedule, and exercisability date — and each one gets its own Nelson calculation.

The result is a table of grants, each apportioned individually, with community and separate property shares calculated row by row. The earlier the grant date relative to separation, the higher the community property percentage tends to be. Later grants — particularly those made close to or after separation — may be predominantly or entirely separate property.

This is not a simple spreadsheet exercise. It requires the full grant history from the employer, precise date calculations, and an understanding of how cliff vesting, performance conditions, and acceleration provisions interact with the formula.

The Hug Formula: Rewarding Past Service

Not all equity awards are forward-looking. Sometimes a grant is made to reward work already done — a retention bonus in equity form, or a special award tied to a milestone the employee already achieved. In those cases, the Nelson formula does not apply.

Instead, California courts use the Hug formula, which runs the apportionment period from the date of employment (not the date of grant) to the date of exercisability. Because the lookback period is longer and begins before the grant, the community property percentage is typically lower under Hug than under Nelson for the same award.

Determining which formula applies — Nelson or Hug — requires looking at the purpose of the grant, which is not always obvious from the grant agreement alone. Employer documentation, offer letters, and bonus plan descriptions can all be relevant.

What This Means if You Are Heading Toward Divorce

If either spouse has unvested equity, here is what you need to gather before you can have a meaningful conversation about division:

• The complete equity grant history, including grant dates, number of shares or units, vesting schedules, and exercisability dates

• Documentation of the purpose of each grant (incentive, retention, performance, etc.)

• The current value of vested and unvested awards

• Any acceleration provisions in the grant agreements or employment contracts

The Nelson calculation itself is not conceptually difficult, but it requires precise inputs and a clear understanding of which grants are subject to apportionment at all. Awards granted entirely after the date of separation are separate property and do not require apportionment.

The Bigger Picture

Equity compensation is one of the most commonly mishandled asset categories in California divorces, partly because clients often do not know what they have, and partly because the formulas are unfamiliar to attorneys who do not regularly handle high-asset cases.

If you are dealing with a spouse who works in tech, finance, or any industry where equity is a significant part of total compensation, getting a forensic accountant involved early is not optional — it is essential. The numbers are too fact-specific and the formulas too technical to estimate reliably without one.

What Documents You'll Need for a Moore/Marsden Analysis

If you own real property that you brought into your marriage — or inherited or received as a gift during it — and that property was purchased with a mortgage, a Moore/Marsden analysis may be necessary to determine how much of the property's equity belongs to you alone and how much belongs to your marital estate.

The analysis sounds technical, and it is. But the foundation of any good Moore/Marsden calculation is simple: documents. The right documents, covering the right dates. Here is what you will need.

A Quick Explanation of Moore/Marsden

When separate property funds are used to purchase a home that is later paid down — even partially — using community income during the marriage, the community acquires a proportional ownership interest in that property. The Moore/Marsden formula calculates that interest based on the ratio of community contributions (mortgage principal paid during marriage) to the total purchase price.

The result is an ownership split, not a reimbursement right. That distinction matters enormously at the time of divorce.

The Documents You Will Need

Chain of Title and Original Purchase

• Buyer's closing or settlement statement from the original purchase. This establishes the purchase price, the down payment amount, the source of the down payment, and the original loan balance — all critical inputs to the formula.

• Grant deed at the time of purchase. This confirms who held title and in what form.

• Any quitclaim deeds recorded on the property. These can affect characterization significantly, particularly if title was changed around the time of marriage.

Mortgage History

Mortgage statements as of the following dates are essential:

• Date of marriage — establishes the loan balance at the start of the community period, which determines how much principal remained to be paid down with community funds.

• Date of separation — establishes how much principal was paid during the marriage, which is the community's contribution to the Moore/Marsden calculation.

• Present date — needed for current equity analysis.

If the loan was refinanced during the marriage, you will need statements bracketing each refinance as well.

Property Valuations

The Moore/Marsden formula requires the property's value at key points in time:

• Date of marriage

• Date of any refinance during the marriage

• Date of separation

• Present date

Formal appraisals are ideal. In some cases, retrospective appraisals or market analyses can be used for historical dates, but the more documentation the better.

Refinance Documents

If the property was refinanced during the marriage, you will need:

• Closing and escrow statements for each refinance

• The promissory note and deed of trust for each new loan

• The HUD-1 or Closing Disclosure showing the payoff of the prior loan and the disposition of any cash-out proceeds

Cash-out refinances are particularly important. If community property equity was cashed out and spent — or if separate property funds were used to pay down a refinanced loan — those facts can significantly affect the calculation.

Property Improvements

Improvements made during the marriage using community funds can affect the property's value and, depending on how they are treated, the equity analysis. Gather:

• Contractor agreements and invoices for all work done during the marriage

• Proof of payment (bank statements, cancelled checks, credit card records)

• Building permits and certificates of completion where applicable

Why This Matters Before You File

Moore/Marsden disputes are among the most document-intensive issues in California family law. The formula is only as accurate as the records behind it. Missing a mortgage statement, losing a closing disclosure, or being unable to trace the source of a down payment can result in a less favorable outcome — or prolonged litigation.

If you are approaching a separation and own property purchased before or during your marriage with a mortgage, start gathering these documents now. The earlier you organize them, the cleaner the analysis — and the stronger your position.

How to start a conversation about a Premarital Agreement that's not awkward

The easiest way to make a prenup conversation awkward is to start with what happens if you break up. That's where most people go, and it immediately puts both people on edge.

A better starting point, and honestly the more important one, is: how do we build wealth together?

Instead of leading with protection or downside risk, you're talking about how you want your financial life to actually function during the marriage. For most couples, that's the part that matters day to day. A prenup is just the structure that supports those decisions.

Here are some questions to ask: Are we treating income earned during the marriage as shared or separate? Are we combining accounts, keeping things separate, or some version of both? If one person contributes more financially early on, does that matter over time, or are we treating everything as fully joint?

Real estate is usually where this gets concrete. If one person is bringing separate property to a down payment, what is that contribution supposed to be? A gift? A loan? An investment that grows with the property? Most people have an instinctive answer, but they haven't thought through how it plays out over time. Walking through that together is almost always more productive than debating abstract ideas about fairness.

Career decisions work the same way. If one person expects to step back, or take on more of the childcare, how does that factor into the way you think about income and long-term wealth building?

Once you've had this conversation, there will probably still be moments where it feels uncomfortable. That's normal. You're talking about money, expectations, and long-term planning all at once. But if it stays anchored in what you're building together, it tends to stay collaborative rather than adversarial.

When Are “Watts Charges” Fair? A Practical Look at Equity in Post-Separation Home Use

In California divorces, one issue that comes up with surprising frequency is whether a spouse should “pay” for living in the family home after separation. The legal concept behind that is called a Watts charge.

But despite how often it’s raised, it’s not automatic. Whether a Watts charge applies at all comes down to one thing: fairness.

What Is a Watts Charge?

A Watts charge comes from a case that allows a court to require one spouse to compensate the community for the reasonable rental value of a shared asset they used exclusively after separation. Most often, that asset is the family home.

The basic idea is straightforward. If one spouse lives in a community property home alone, there may be a financial imbalance that needs to be addressed.

But that’s only the starting point.

Courts Have Broad Discretion

There’s no formula and no default rule that Watts charges must be imposed. Courts have wide discretion to decide whether a charge is appropriate at all, what amount, if any, is fair, and whether to reduce or deny it entirely. These decisions are made case by case, based on the full set of circumstances. Courts regularly decline to impose Watts charges when doing so would lead to an inequitable result. That flexibility is important because the reality of separation is rarely clean or symmetrical.

Why Watts Charges Are Not Automatic

One key point that often gets overlooked is that Watts charges are not meant to be routine. Courts are directed to consider all the circumstances surrounding exclusive use of the property. That includes how and why one spouse remained in the home, what the parties understood at the time, and whether imposing a charge later would be fair. In practice, several factors tend to matter.

Notice and expectations. If a spouse intends to seek Watts charges, timing matters. It is common practice to give early, written notice. Without that, the other spouse may reasonably assume no charge will be pursued and make financial decisions based on that assumption. Late claims, especially retroactive ones, can be viewed as unfair if they disrupt those expectations.

Delay and prejudice. When a claim is raised long after separation, courts may look at whether the delay caused harm. If one spouse relied on the absence of a claim and chose not to seek support earlier, that reliance can weigh against imposing retroactive charges. This is where the doctrine of laches comes into play. If a party waits too long and that delay creates prejudice, the court can decline to enforce the claim.

Voluntary move-out. Watts charges are less compelling when the non-occupying spouse chose to leave. If one party voluntarily vacates the home, especially to avoid disrupting children, courts often view the situation differently than if one party was excluded or forced out.

Presence of children. When one spouse remains in the home with the children, particularly as the primary caregiver, that context matters. The home is not just a financial asset. It is also stability for the children.

Financial reality during separation. Courts look at the full financial picture, including whether the occupying spouse was receiving support, whether they had independent income, and whether community funds were already covering expenses. If one spouse had limited means, a Watts charge may not be appropriate.

Actual economic impact. In some cases, there is little or no real financial harm to the non-occupying spouse. For example, if there is no mortgage on the property, the cost of one spouse staying in the home may be minimal. That can weigh against imposing a charge.

Retroactive Watts Charges Are Especially Scrutinized

One of the most contested issues is whether Watts charges should apply retroactively. Courts are often hesitant to allow this, particularly when there was no early notice, the claim was not raised in initial filings or disclosures, or the delay affected the other party’s financial decisions. In those situations, courts may deny retroactive charges entirely.

How Watts Charges Interact With Support

Even when a court is open to the idea of a Watts charge, it does not necessarily result in a payment from one spouse to the other. Courts can treat the value of living in the home as part of the broader support analysis. In some cases, the use of the home is effectively considered a substitute for support during that period. That flexibility allows courts to avoid double counting or creating outcomes that do not reflect the reality of how the parties lived during separation.

The Takeaway

Watts charges are not a default rule or a guaranteed entitlement. They are an equitable tool. That means the analysis is not just who lived in the house, but also why they stayed, what the parties expected, how the situation unfolded over time, and whether imposing a charge now would be fair. In many cases, especially where there was no notice, a voluntary move-out, or children in the home, courts will reduce or deny Watts charges altogether. The practical takeaway is simple. If you are considering a Watts claim, timing and context matter as much as the underlying legal theory.

Options for Addressing Spousal Support in Relationship Agreements

Options for Addressing Spousal Support in Relationship Agreements

Spousal support is often the most emotionally charged and least understood part of a prenuptial or marital agreement. Many couples avoid the topic entirely, only to discover later that silence is still a choice, just one that hands control to the law in effect at the time of divorce.

There are generally three ways couples approach spousal support in relationship agreements. Each comes with different tradeoffs around predictability, flexibility, and risk.

1. Say Nothing and Rely on the Law

One option is to leave spousal support unaddressed. If the relationship ends, support will be determined under the laws of the jurisdiction where the divorce takes place.

This approach can feel simpler up front, but it carries real uncertainty. Spousal support rules vary widely from state to state, and even within the same state, the law can change significantly over time. What feels fair or predictable today may look very different ten or twenty years from now, especially if income, health, or family structure changes.

Choosing silence effectively means opting into an unknown future legal framework.

2. Create Your Own Rules

Many couples prefer to define their own spousal support framework rather than relying on default laws. This does not mean predicting every possible future scenario. It means agreeing on principles and guardrails that reflect shared values and realistic expectations.

Common approaches include tying support to the length of the marriage, with different outcomes for shorter versus longer marriages. Others incorporate specific life events or conditions, such as having children, stepping out of the workforce, disability, or reaching certain asset or income thresholds.

Some agreements place durational limits on support, while others use formulas to create predictability, such as a percentage-based calculation or a split of net spendable income. In some cases, couples agree to a buyout of spousal support. This can work well, but it needs to be structured carefully to avoid enforceability issues, including concerns that one party is financially incentivized to divorce.

The key benefit of this approach is intentionality. The rules are tailored to the couple, rather than imposed later by a court.

3. Complete Waiver of Spousal Support

A third option is a full waiver of spousal support. This is most appropriate where the underlying facts support it and where both parties are comfortable with the risk allocation.

Waivers are often based on existing wealth, such as where both parties have substantial assets, or where each party has independent and comparable financial security. In other cases, a waiver may be appropriate when earning capacities are similar and expected to remain so.

Because courts scrutinize spousal support waivers closely, especially in long-term marriages, the reasoning behind the waiver matters. A well-drafted agreement explains why the waiver is fair at the time it is signed, not just what the waiver says.

Choosing the Right Approach

There is no single right answer. The best spousal support provision is one that matches the couple’s actual financial dynamics, anticipated life paths, and tolerance for uncertainty. What matters most is not avoiding the conversation, but having it thoughtfully and with eyes open to the long-term consequences.

If you want help thinking through which framework aligns with your situation, that conversation often reveals far more about values and expectations than the legal clause itself.
