You have spent years quietly counting your unvested RSUs as part of the family net worth. If you died tomorrow, a large share of that number might never reach your spouse at all.

For a dual-income Bay Area tech household, unvested equity is often the single biggest line on the balance sheet, larger than the house minus the mortgage. We plan around it, we fold it into the long-term math, we let it shape how much we spend and how we think about the years ahead. We even count it toward the financial independence number. What we rarely do is ask what it becomes on the one day nobody wants to picture.

This piece walks through what happens to unvested equity when an employee dies or becomes disabled, why the plan document rather than the offer letter decides it, how disability coverage fits into the picture, and what a surviving spouse is actually left holding. It is planning education, not legal advice. Part of the answer is knowing exactly when to put an estate attorney in the room.

The number on your balance sheet you do not own yet

Unvested equity is a promise with a condition attached. The condition is that you keep working, quarter after quarter, until each tranche vests. That is easy to forget when a grant is large and the vesting feels automatic, but the conditional part is the whole story here.

Death and disability are the two events that end employment without a resignation and without a firing. They are also the two cases almost nobody checks before it matters. In many equity plans, unvested awards are simply forfeited when employment ends, and depending on the plan, death or the onset of a disability can count as employment ending. That treatment varies by plan, so the only reliable answer is the one written in your own documents.

Sit with what that means. The RSUs and options you have mentally spent may evaporate at the precise moment your family needs them most. This is why treating vesting equity like money already in the bank is risky. Whether it survives you depends entirely on paperwork you probably have not opened since your first week on the job.

The plan document controls, not your offer letter

Here is the distinction that trips up smart people. The offer letter you negotiated is a summary. The equity incentive plan and your individual grant agreement are the contract. What happens to unvested awards on death or disability is generally governed by those plan and grant documents, not by the friendly one-page letter, though the exact hierarchy varies by plan and is worth confirming in yours.

Most people signed the plan and grant agreement with a single click and never read the sections that matter now. Those sections are dense, they are written in legal language, and they interact with your estate documents in ways that are not obvious. This is not a place to guess from memory or from a blog post.

This is where an estate attorney earns the fee, and where reading the actual plan is the job. Interpreting death, disability, and change-of-control language in an equity plan is legal work, not something to improvise on your own. Pull the plan document and every grant agreement, and have a qualified attorney read the relevant provisions against your will and trust. The point of doing it now is to know the answer before anyone has to live with it.

Accelerated vesting is a maybe, not a promise

You may have heard that equity accelerates if you die. Sometimes it does. Some plans accelerate unvested awards fully on death or disability, some accelerate a portion, some accelerate nothing, and some leave it to the discretion of the board or a committee. Which of those applies to you is a plan-specific fact you cannot assume, so check your own documents rather than the general rule of thumb.

The definitions matter as much as the mechanics. The way a plan defines disability can be narrow, and it can differ from the way your insurance policy defines the same word, which means one could pay out while the other does not. These are details that live in the fine print and vary from plan to plan, so treat any general statement as a prompt to read yours.

If you hold options rather than restricted stock, the stakes get sharper, because the type of option you have changes the deadlines and the tax exposure your family would face. Do not assume acceleration and do not assume forfeiture. Get the actual language read. The planning value is knowing which world you are in before it is ever tested.

Disability is the case people skip

Death gets the attention because life insurance is a familiar product. Disability gets skipped, even though becoming unable to work is statistically more common during your earning years than dying is. And it carries a double hit. Your income stops, and depending on your plan, your unvested equity may stop vesting at the same time.

I am a fee-only advisor, and I do not sell insurance, so this is about how the coverage works rather than what to buy. There are questions worth understanding before you ever need to file a claim. One is whether a policy uses an own-occupation or an any-occupation definition, because that governs whether benefits pay when you cannot do your specific job versus any job at all. Another is whether coverage is group coverage through your employer, which usually ends when the job does, or an individual policy you own and can carry with you.

Two more concepts round it out. An elimination period is the waiting stretch between the disabling event and the point benefits begin. And how benefits are taxed can depend on who paid the premium and with what kind of dollars. Those tax details change and deserve verification rather than a rule quoted from memory.

What your spouse is actually left holding

Now picture the surviving spouse, months later, trying to piece it together. They inherit the vested shares, which for a tech household are usually concentrated in a single company at exactly the wrong time to be forced into decisions. What they do not automatically inherit is the unvested portion, unless the plan accelerates it.

Then come the deadlines. When options do vest or accelerate, plans commonly require them to be exercised within a short window after death, and exercising can demand real cash the estate may not have on hand. Whether that window is short or generous varies by plan, so it belongs on the list of things to confirm in your own grant agreements. Who actually receives the shares is often controlled by the beneficiary designation on the equity account and by the plan terms, which can diverge from what your will says, and reconciling those is an attorney’s job.

There is a tax dimension too. Inherited shares may receive a step-up in cost basis, which can matter a great deal for a concentrated position, but the rules and thresholds change over time and should be verified with a professional rather than assumed. Your spouse should not be learning any of this under a deadline. They should already know what the household holds, what would accelerate, and what would have to be acted on quickly.

The bottom line

The unvested equity you count every quarter is a conditional promise, and death or disability is the moment those conditions get tested. Read the actual plan document and grant agreements with an estate attorney, understand how disability coverage works before you need it, and make sure your spouse already knows what the household holds and what would have to happen fast. The planning is not about predicting the worst day. It is about making sure that day does not also become the day your family discovers the money was never fully theirs.
