California is a community property state, meaning all income earned and assets acquired during marriage are owned equally by both spouses. Under the California Uniform Premarital Agreement Act (Family Code §1610-1617), a prenuptial agreement lets you override this default 50/50 split and define your own rules.
San Francisco is a global tech and venture capital center where equity compensation often dwarfs base salary. Stock options, RSUs, pre-IPO shares, SAFE notes, and carried interest are common forms of wealth. Without a prenup, any equity that vests during marriage — even from pre-marital grants — becomes community property. San Francisco Superior Court Family Division regularly handles divorces where tech equity worth tens of millions is at stake.
SignAI generates your San Francisco prenuptial agreement with the right legal language automatically — including compliance with California Family Code, proper financial disclosure requirements, the mandatory seven-day review period, and detailed provisions for classifying tech equity and venture capital interests.

What's included
Every Prenup generated by SignAI for California includes these essential provisions — automatically.
Full legal names, addresses, and financial disclosure summaries for both parties — required for enforceability under California law.
Clear identification of each partner's pre-marital assets, including tech equity, pre-IPO shares, VC fund interests, San Francisco real estate, and cryptocurrency holdings.
Specific terms for how income, stock vesting, carried interest, and investments made during the marriage will be classified — opting out of California's default 50/50 split where desired.
Agreed-upon terms for spousal support, including amount, duration, and conditions. California requires independent counsel for both parties when waiving support.
Protection from each other's pre-existing debts, including startup liabilities, student loans, and venture fund capital calls.
Governing law clause specifying California jurisdiction, venue selection for San Francisco County courts, and compliance with California Family Code §1610-1617.
Use cases
People in California use SignAI to create Prenups for a wide range of situations. Here are the most popular:
In San Francisco, equity compensation often represents the largest portion of a tech worker's wealth. A prenup defines how pre-marital stock grants, RSU vesting schedules, and pre-IPO shares are classified — preventing community property claims on your tech wealth.
Try it: “I'm a tech worker in San Francisco and need a prenup to protect my stock options and pre-IPO shares”
VC fund managers often earn carried interest that takes years to vest. A prenup can classify pre-marital carry as separate property and define rules for carry earned during the marriage.
Try it: “I'm a VC partner in SF and need a prenup to protect my carried interest”
San Francisco real estate is among the most expensive in the world. If you own a home in Pacific Heights, the Marina, or Noe Valley, a prenup ensures your pre-marital equity is not divided as community property.
Try it: “I need a prenup to protect my San Francisco home before getting married”
If you co-founded a company before marriage, a prenup keeps your founder equity separate. It protects your co-founders from involuntary involvement in divorce proceedings and prevents forced business valuations.
Try it: “I'm a startup founder in SF and need a prenup to protect my company equity”
FAQ
Yes. Prenuptial agreements are enforceable under the California Uniform Premarital Agreement Act (Family Code §1610-1617). Both parties must sign voluntarily, provide full financial disclosure, and have at least seven calendar days to review the agreement. SignAI's e-signatures are legally valid under UETA and the federal ESIGN Act.
Yes. A prenup can classify your founder shares, stock options, and advisor equity as separate property. Without a prenup, California courts may determine that the community (the marriage) contributed to the company's growth and award your spouse a portion of the equity's value.
Without a prenup, RSUs and stock options that vest during marriage are community property — even if the grant was made before the wedding. California courts apply time-based formulas to allocate the community's share. A prenup lets you define clear classification rules upfront.
California Family Code §1615 requires that the party who did not primarily draft the prenup have at least seven calendar days between receiving the final agreement and signing it. This mandatory cooling-off period protects against coercion — violating it can invalidate the entire prenup.
Yes. A prenup can classify pre-marital cryptocurrency and digital assets as separate property, and define how crypto acquired or appreciated during marriage is treated. Given crypto's volatility, clear classification rules in a prenup are especially valuable.
