Prenup Boom: 53% of Under-45 Americans Signed One (2026 Data)

A July 2026 Harris Poll found 53% of engaged/married Americans under 45 have a prenup. What NY's DRL § 236B means for you.

By Antonio G. Jimenez, Esq.New York4 min read

A Harris Poll of 2,148 adults conducted for Bloomberg and released July 6, 2026, found that 53% of engaged or married Americans under 45 had signed a prenuptial agreement as of May 2026 — up from roughly 8% in the 1990s. For New Yorkers, this matters because a prenup signed under N.Y. Dom. Rel. Law § 236 is presumptively enforceable, making it one of the most powerful planning tools available before marriage.

Why this prenup surge matters legally

The rise from 8% in the 1990s to 53% today signals that prenuptial agreements have shifted from an elite estate-planning tool to a mainstream financial decision. The Bloomberg report, citing the Harris Poll, documented that prenup adoption among Gen Z rose from 41% in 2022 and among millennials from 34% in 2022. Legally, this trend expands the pool of couples entering marriage with contractually defined property rights rather than relying on default statutory rules.

The most legally significant finding is that women now initiate roughly half of all prenups, according to family-law attorneys quoted by Bloomberg. This reflects a shrinking gender earnings gap and later marriage ages. When both spouses bring assets, income, or business interests to the marriage, a prenup lets them override the state's default division scheme with tailored terms — a decision courts respect when the agreement is properly executed.

How New York law handles prenuptial agreements

New York enforces prenuptial agreements under N.Y. Dom. Rel. Law § 236(B)(3), which requires that the agreement be in writing, signed by both parties, and acknowledged with the formality required to record a deed. This acknowledgment requirement is stricter than in many states — an unacknowledged prenup is void in New York regardless of the parties' intent, as the Court of Appeals confirmed in Matisoff v. Dobi (1997).

Beyond formalities, New York courts may set aside a prenup that is unconscionable or the product of fraud, duress, or overreaching. Unlike the 27 states that follow the Uniform Premarital Agreement Act, New York applies its own contract-law standards. A prenup that waives equitable distribution is generally upheld, because N.Y. Dom. Rel. Law § 236(B)(5) governs property division only in the absence of a valid agreement.

New York also permits spouses to modify support obligations by contract, though a waiver of spousal maintenance will not be enforced if it would leave one spouse a public charge. Because both spouses increasingly bring income and assets, a well-drafted New York prenup should address separate property, appreciation of premarital assets, business interests, and maintenance. Couples researching this should compare a prenuptial agreement with a postnuptial agreement, which serves couples who marry first and contract later.

Practical takeaways for New York couples

  1. Get separate lawyers. Independent counsel for each spouse is the single strongest defense against a later claim of duress or overreaching. New York courts scrutinize agreements where one party had no attorney.

  2. Sign well before the wedding. A prenup presented days before the ceremony invites a duress argument. Aim to finalize the agreement at least 30 days before the wedding date, with full financial disclosure exchanged in writing.

  3. Satisfy the acknowledgment rule. Under N.Y. Dom. Rel. Law § 236(B)(3), both signatures must be acknowledged before a notary with deed-level formality. Skipping this step voids the entire agreement.

  4. Disclose everything. Full and fair disclosure of assets, debts, and income protects enforceability. Hidden accounts or undervalued businesses are the leading grounds for challenging a prenup.

  5. Revisit after major changes. A prenup drafted before children, a business sale, or a large inheritance may need updating. A personalized divorce roadmap can help you understand how your existing agreement interacts with current New York law, and if you anticipate a dispute you can find a divorce attorney in your county.

The prenup boom reflects a generation approaching marriage with clearer eyes about money and risk. If you are engaged and considering an agreement — or reviewing one already signed — a consultation with a New York family-law attorney can confirm whether your document meets the state's exacting standards before you rely on it.

Key Questions

Are prenuptial agreements enforceable in New York?

Yes. Under N.Y. Dom. Rel. Law § 236(B)(3), a prenup is presumptively enforceable if it is written, signed, and acknowledged with deed-level formality. New York courts can void agreements that are unconscionable or signed under fraud or duress, but properly executed prenups are routinely upheld.

What percentage of young Americans have a prenup in 2026?

A Harris Poll released July 6, 2026, found 53% of engaged or married Americans under 45 had signed a prenuptial agreement as of May 2026 — up from about 8% in the 1990s and from 41% of Gen Z and 34% of millennials in 2022.

Does a New York prenup have to be notarized?

Yes. N.Y. Dom. Rel. Law § 236(B)(3) requires both signatures to be acknowledged before a notary with the same formality used to record a deed. An unacknowledged prenup is void in New York, as confirmed in Matisoff v. Dobi (1997), regardless of the parties' intent.

How long before the wedding should a prenup be signed in New York?

There is no fixed statutory deadline, but attorneys recommend finalizing a prenup at least 30 days before the wedding. A last-minute agreement invites a duress challenge. Early signing, paired with full financial disclosure, strengthens enforceability under New York contract standards.

Can a prenup waive spousal support in New York?

Generally yes. New York permits spouses to modify or waive maintenance by contract under N.Y. Dom. Rel. Law § 236. However, a court will not enforce a maintenance waiver if it would leave one spouse a public charge dependent on government assistance at the time of divorce.
