A Harris Poll of 2,148 U.S. adults released by Bloomberg on July 6, 2026 found that 53% of engaged or married Americans under 45 have signed a prenuptial agreement as of May 2026 — roughly double the ~20% rate among married couples overall. For California residents, this surge makes it critical to understand Cal. Fam. Code § 1615, which sets strict enforceability rules that can void a prenup signed without proper disclosure or a seven-day review period.

Why this matters legally
This data confirms that prenuptial agreements have shifted from a niche tool for the wealthy into a mainstream financial planning instrument for couples under 45. The Harris Poll reported that the 53% figure represents a jump from roughly 37% in 2022 — a near doubling in four years. That growth matters legally because a poorly drafted prenup is worse than no prenup at all: it creates false security that collapses in court.
In California, a prenuptial agreement is only as strong as its compliance with statutory formalities. The Bloomberg reporting highlights that women — including higher earners and those planning to leave the workforce — are increasingly initiating these agreements to protect inheritances, student debt, frozen embryos, and creator-economy assets. Each of those asset categories raises distinct legal questions under California's community property regime, and a generic online template rarely addresses them adequately.
How California law handles this
California enforces prenuptial agreements under the Uniform Premarital Agreement Act, codified at Cal. Fam. Code § 1600 through § 1617. Under Cal. Fam. Code § 1615, a prenup is unenforceable if the party challenging it proves either that they did not sign voluntarily, or that the agreement was unconscionable when signed and they lacked adequate disclosure of the other party's assets.
California imposes a strict seven-day rule: under Cal. Fam. Code § 1615(c), an agreement is not considered voluntary unless the party had at least seven calendar days between first receiving the final agreement and signing it. This waiting period cannot be waived and exists specifically to prevent the "sign this before the wedding" pressure the Bloomberg piece describes among rushed young couples.
California also treats spousal support waivers with heightened scrutiny. Under Cal. Fam. Code § 1612, a provision waiving or limiting spousal support is unenforceable if the party was not represented by independent counsel when the agreement was signed, or if the term is unconscionable at the time of enforcement. This is a stronger protection than many states offer, and it directly affects the higher-earning women the poll identified — a support waiver they negotiate today can still be struck down years later.
Because California is a community property state under Cal. Fam. Code § 760, earnings and assets acquired during marriage are presumptively divided 50/50 at divorce. A prenup is the primary legal mechanism to opt out of that default. For couples protecting a business, an inheritance, or creator-economy income streams, the agreement must clearly characterize those assets as separate property and address any appreciation or commingling that occurs during the marriage.
Practical takeaways
-
Give yourself the seven days. Under California law, sign the final agreement at least seven calendar days after receiving it. A prenup rushed into the week before the wedding is the single most common ground for a voluntariness challenge under Cal. Fam. Code § 1615.
-
Get independent counsel on both sides. If your agreement waives or caps spousal support, Cal. Fam. Code § 1612 requires independent representation for that waiver to hold. Two separate attorneys is the standard, not a luxury.
-
Disclose everything in writing. Attach a full schedule of assets and debts. Inadequate disclosure is a statutory ground for voiding the agreement, and student debt — a top concern in the poll — must be listed explicitly to be assigned as separate.
-
Address modern assets by name. Frozen embryos, cryptocurrency, and creator-economy income (channels, brand deals, follower monetization) should be named specifically. Courts cannot enforce silence.
-
Consider a postnuptial agreement if you are already married. The 53% figure includes married respondents, and California permits post-marriage agreements under similar disclosure standards, though the fiduciary duty between spouses raises the bar.
