Prenup for Startup Founders - Protecting Equity, Stock Options & IP
This article is for general informational purposes only and does not constitute legal advice. For advice tailored to your circumstances, consult a licensed attorney.
Key Takeaways
- Options and shares accumulated during the marriage are considered joint property under the Property Relations Law — even if registered solely in one employee's name
- ESOP and RSU that have not yet vested are divided in divorce according to the "time rule" — the ratio of the marriage period to the total vesting period
- Intellectual property and patents developed before marriage can be protected by a prenup, but their appreciation during the marriage may be deemed shared
- Personal goodwill has been recognized by Israeli courts as a divisible asset — a startup founder whose value grew through their work is exposed to an equalization claim
- Noberu allows itemizing digital assets, options, and shares in Step 2 of the questionnaire — with a protection mechanism tailored to tech employees
Why Tech Couples Need a Specialized Prenup
The tech industry has created a new kind of wealth - one that looks nothing like a house or a bank account. Stock options, restricted stock units (RSUs), ESOP plans, intellectual property, and patents are assets whose value can jump from a few thousand shekels to millions overnight, or become worthless. When a couple divorces, the question of "who owns what" becomes extraordinarily complex and expensive.
Under Israel's Property Relations Law (1973), assets accumulated during marriage are split equally - unless a prenuptial agreement says otherwise. That means stock options worth millions that you received from your company could be divided, even if your spouse never worked a single hour at your startup.

How ESOPs, RSUs & Stock Options Are Divided in Divorce
The Time Rule
Israeli courts divide stock options and RSUs using the "time rule":
Shared portion = (marriage duration during vesting ÷ total vesting period) × 50%
Numerical example:
- Dana received 10,000 options with a 4-year vesting schedule
- Dana married one year before receiving the options
- After 3 years of marriage, they divorce
- Marriage overlap with vesting: 3 out of 4 years
- Shared portion: (3 ÷ 4) × 50% = 37.5% of options belong to the spouse
- If the options are worth NIS 2 million - the spouse is entitled to NIS 750,000
Without a prenup, this is the automatic outcome. With a prenup, you can set entirely different rules - for instance, defining options received as part of a compensation package as separate property.
Pre-Marriage Options That Vest During Marriage
Even options granted before marriage can be partially shared. If they were awarded before the wedding but vested during the marriage, the portion that vested during the marriage is considered shared property. A prenup can explicitly define all options - including those vesting in the future - as separate property.
Intellectual Property & Patents
IP as Separate Property
Technology, algorithms, or patents you developed before marriage remain separate property. But two problems arise:
- Appreciation in value - If your IP was worth NIS 100,000 on your wedding day and NIS 10 million on the day of divorce, the court may rule that the growth (NIS 9.9 million) is shared property - especially if you invested time and effort during the marriage to develop it.
- IP created during marriage - Any new intellectual property created during the marriage is shared property, even if only one spouse worked on it.
What to Include in Your Prenup
A solid tech-sector prenup should specifically address:
- A detailed inventory of existing IP on the signing date, with estimated value
- A protection mechanism for new IP developed during marriage
- Ownership of license income, royalties, and IP sale proceeds
- A clear definition of what constitutes "joint investment" in IP
Personal Goodwill - The Most Surprising Divisible Asset
Personal goodwill is the economic value derived from a person's reputation, connections, knowledge, and skills. Israeli courts have recognized personal goodwill as a divisible asset in divorce proceedings.
For startup founders, this means: if your startup's value grew thanks to your personal efforts, the court may determine that part of that growth is shared marital goodwill.
Example: Yoav founded a SaaS company before marriage. During the marriage, he raised $20 million, built a team of 50, and the company is now worth $100 million. His spouse could argue that a significant portion of that value is Yoav's personal goodwill built during the marriage - and therefore shared.
A prenup can explicitly state that personal goodwill is not shared property and that each party retains their own goodwill.
Pre-Marriage vs. During-Marriage Business Value
| Asset type | Example | Default status | With prenup |
|---|---|---|---|
| Pre-marriage asset | Founder shares, IP, savings | Separate (with exceptions) | Separate - explicitly defined |
| During-marriage asset | RSUs, new options, salary | Shared | Can be defined as separate |
| Appreciation of separate asset | Startup value growth | Disputed - depends on circumstances | Pre-defined in the agreement |
The third row is the big problem in tech divorces. Without a prenup, the court decides - and that can cost millions.

Practical Scenarios
Scenario 1: Startup Founder
Rotem founded a startup before marriage with 40% of shares. During the marriage, she raised Series A and B, and the company is now worth NIS 200 million. Without a prenup, her spouse may claim part of the value appreciation.
Scenario 2: Tech Employee with RSUs
Adam works at Google Israel and receives RSUs worth $500,000 per year. After 5 years of marriage, he has accumulated RSUs worth $2 million. In a divorce, his spouse is entitled to 50% - about $1 million - even if she never worked at Google.
Tax Implications - Section 102 Traps
Employee stock options in Israel are primarily governed by Section 102 of the Income Tax Ordinance. In a divorce, dividing options may trigger a tax event - a deemed realization that creates an immediate tax liability.
A well-drafted prenup also addresses tax:
- Who bears the tax burden when options are exercised?
- Is share division in divorce considered a "sale" for tax purposes?
- How does the prenup affect passive income taxation?
Registering the prenup with the Tax Authority is especially important when high-value assets are involved.
How Noberu Handles Tech Assets
The Noberu questionnaire includes Step 2 - "Assets" - where you can detail:
- Shares and options by company, quantity, and type (ESOP, RSU, phantom shares)
- Intellectual property - patents, trademarks, copyrights
- Digital assets - crypto, NFTs, and digital assets
- Estimated value and future valuation mechanism
The final agreement includes dedicated clauses protecting these assets, certified by a notary or court for legal validity.
The Bottom Line
If you work in tech, founded a startup, or hold options and shares - a prenup isn't a luxury, it's a necessity. Without one, you're exposed to asset division that could cost millions and damage the company you built.
The cost of a prenup in 2026 is a tiny fraction of what you'd pay in a divorce without one. It's not distrust - it's smart protection for what you've built.
