How an IPO or Acquisition Affects a California Divorce
Quick Answer: A liquidity event, an IPO, an acquisition, or a tender offer, turns paper equity into real money. What it does not do is change who owns what. That was already decided by your date of separation and by when the equity was earned. Equity earned through your work during the marriage stays community property even if it becomes liquid years after you separate. The date of separation is the single most valuable date in an equity heavy divorce, which is exactly why it gets fought over when a big exit is on the horizon.

What a Liquidity Event Actually Is
A liquidity event is the moment equity you hold on paper can be turned into cash or freely tradable stock. A few forms come up most often.
An IPO, an initial public offering, is when a private company first sells shares to the public and its stock begins trading. An acquisition is when another company buys yours, often paying out your equity in cash or in acquirer stock. A tender offer or secondary sale lets employees sell some shares to investors while the company is still private. A direct listing takes a company public without raising new money, and a SPAC merger takes a company public by merging it into an already public shell.
Two features of these events matter enormously in a divorce.
The lockup period. After a traditional IPO, company insiders usually cannot sell for a window that is commonly around 180 days, sometimes released in stages. You may owe tax the moment the equity becomes yours, while being unable to sell a single share to pay it.
Double trigger vesting. At private companies, RSUs frequently carry two conditions. The first is time based, met by staying employed. The second is the liquidity event itself. Both must happen before the shares actually settle and become yours. This is the quiet engine of many equity divorces, because a person can satisfy the time trigger entirely during the marriage, leaving a large block of equity that was fully earned by marital work but does not turn real until an IPO or acquisition that may be years away.
With those basics in place, the timing rules make sense.
The Date of Separation Is the Most Valuable Date in the Case
Under Family Code § 70, the date of separation is a complete and final break in the marriage, shown by one spouse expressing the intent to end it and conduct consistent with that intent. It is not a casual milestone. It is the cutoff that sorts community property from separate property.
In an equity heavy estate, that cutoff is doing extraordinary work. It sits inside the time rule fractions that apportion unvested RSUs and stock options, which we cover in our post on dividing RSUs and stock options. It sets the line for how much of a founder's business growth is community, which we cover in our post on founder equity. Move the date by a few months and you move the community share on every unvested grant and on the appreciation of the company. In a case headed toward a major exit, that movement is measured in the millions.
Earned Versus Liquid: Two Different Clocks
Here is the idea that catches almost everyone. Two separate clocks run on your equity, and people confuse them constantly.
The first clock is when the equity was earned, through your work. That clock decides characterization, whether the equity is community or separate, and it is measured against the date of separation.
The second clock is when the equity became liquid, the IPO or acquisition. That clock decides timing and tax, when the money and the tax bill actually arrive.
These two clocks can be years apart, and the gap is where value is won or lost. Picture equity that finished its time based vesting while you were married but did not settle because the company was still private. The IPO finally lands eight months after you separate. The cash shows up after separation, but the work that earned it happened during the marriage. Under Family Code § 771, what you earn after separation is your separate property, yet that section turns on when the earning happened, not when the check cleared. Equity earned during the marriage keeps its community character even though it turned liquid afterward.
Why People Fight About the Date When an Exit Is Near
Because the date of separation is the cutoff, it becomes the most contested fact in the case the moment a large liquidity event is in view. A spouse who can see an IPO coming has every incentive to argue for an earlier separation date, and the other spouse for a later one.
California law does not let you simply choose a convenient date. Section 70 requires both intent and conduct consistent with that intent, judged on the actual evidence, the messages, the living arrangements, the finances, and the behavior of both people. You cannot manufacture a separation date to move equity out of the community, and a court that sees the maneuver will not reward it. This is precisely why the separation date deserves to be treated as a financial issue, with evidence, from the very start of the case.
Lockup Periods and the Timing Trap
A liquidity event can create a strange squeeze. The shares become yours and the tax becomes due, but the lockup means you cannot sell to raise the cash. A settlement drafted as if the equity were instantly spendable can leave one or both people scrambling. A careful agreement accounts for the lockup, decides who carries the market risk while the shares cannot be sold, and plans for the tax that lands before the stock can be touched.
Acceleration on an Acquisition
Some equity carries acceleration, meaning an acquisition can vest a block of shares all at once. Single trigger acceleration vests on the deal itself. Double trigger acceleration vests only if the deal is followed by losing your job. Either way, the question for the divorce is the same. The acceleration controls when the equity vests, but characterization still turns on when the work that earned it was performed, measured against your date of separation.
Taxes Compress Into One Year
A liquidity event can pile years of accumulated equity income into a single tax year, often at the highest brackets, with employer withholding that frequently falls short of the real bill. Two rules follow. Value the equity after the embedded tax, not before, or any buyout figure will be wrong. And decide in writing who bears that tax, because a transfer between spouses is generally not taxed when it happens, but the tax follows the shares to whoever later sells. The numbers belong to your tax advisor. The job in the divorce is to make the after tax picture visible before anyone signs.
Disclosure When an Exit Is Coming
A spouse who knows a liquidity event is near cannot quietly rush a lowball settlement or leave the equity out of the picture. Family Code § 1100 imposes a fiduciary duty of full disclosure on community assets, and Family Code § 1101 backs it with serious remedies, reaching in extreme cases up to the full value of a concealed or understated asset. A pending IPO or acquisition is exactly the kind of material fact that must be disclosed. Honesty here is not optional, and the consequences of hiding the ball are severe.
How It Gets Divided Around a Pending or Possible Exit
Once the community share is settled, there are two main ways to divide it when an exit is involved.
Buyout or offset. You assign a present value to the community share now and trade it against other assets, so one spouse keeps the equity and its upside and the other takes more of the house, the cash, or the retirement accounts. This gives a clean break but requires agreeing on a value for something whose future is uncertain.
Deferred division tied to the event. The other spouse receives their portion if and when the liquidity event happens, after tax. This shares the real risk that the exit never comes, but it keeps the two of you financially connected until it does, which has to be drafted with care.
The right structure depends on how likely and how near the exit is, and on how much risk each person is willing to carry. Pretending a private company will certainly go public can be as unfair as pretending it never will.
The Difference Between Explaining the Law and Modeling It
Many firms can tell you the date of separation matters. The harder work is showing exactly how much it matters for your equity, modeling each grant and each share class across both clocks, the earning clock and the liquidity clock, then valuing the result after tax and after the trade against every other asset. That is where legal training and financial training have to work together. The question is rarely just what the law says. It is what your equity is truly worth to you once the timing, the tax, and the structure are all accounted for.
Frequently Asked Questions
What counts as a liquidity event?
An IPO, an acquisition, a tender offer, a secondary sale, a direct listing, or a SPAC merger. Each one turns equity you hold on paper into cash or freely tradable stock, but none of them changes whether the equity is community or separate property.
If my company goes public after we separate, does my spouse still get a share?
Possibly, yes. Characterization turns on when the equity was earned through your work, not when it became liquid. Equity earned during the marriage can keep its community character even if the IPO or acquisition happens after your date of separation.
Can I just pick a date of separation that protects my equity?
No. Family Code § 70 requires both an intent to end the marriage and conduct consistent with that intent, judged on the actual evidence. A date chosen to move equity out of the community will not hold up, and a court that sees it will not reward it.
What is a lockup period and why does it matter in my divorce?
After an IPO, insiders usually cannot sell for a window commonly around 180 days. You may owe tax when the equity becomes yours but be unable to sell to pay it, so a settlement should account for the lockup and decide who carries the risk during it.
Will an IPO or acquisition change my taxes in the divorce?
It can compress years of equity income into a single tax year at high rates. Equity should be valued after that tax, and the settlement should state in writing who bears it, since the tax follows the shares to whoever later sells.
Do I have to tell my spouse the company might go public?
Yes. A pending or likely liquidity event is a material fact, and Family Code § 1100 requires full disclosure of community assets. Concealing it is a fiduciary breach under Family Code § 1101, with serious remedies.
