Roughly one in five married couples in the U.S. now has a prenuptial agreement, and that rate more than doubles among millennials and Gen Z, according to reporting on the trend that tracks how quickly the document has moved down the age ladder. A generation ago, a prenup was shorthand for one thing: a wealthy person protecting assets from a spouse they didn’t fully trust. Today it’s showing up in relationships where neither person owns a car outright, let alone a house, and the reasoning behind it has almost nothing to do with suspicion.
The numbers behind the shift
The clearest signal of how far prenups have traveled from their old reputation comes from the Harris Poll’s own research: 15% of Americans who have been married or are currently engaged say they’ve signed one, up from just 3% in 2010. That’s a fivefold increase in roughly a decade. The same research found 42% of U.S. adults support the general use of prenups, and 35% of unmarried respondents said they’re likely to sign one themselves down the road. None of that describes a niche legal tool reserved for the wealthy anymore. It describes a document quietly becoming a normal part of getting married at all.
The generational skew matters as much as the raw growth. If overall prenup adoption sits around 20% and the rate for younger couples is more than double that, Gen Z and millennials aren’t just participating in the trend, they’re driving it. That runs counter to the assumption that prenups require real assets to justify the paperwork. Younger couples are opting in earlier, often before either partner has accumulated much of anything worth dividing.
Divorce attorneys are seeing the same pattern from their side
Family law attorneys have been documenting this shift for years. A survey from the American Academy of Matrimonial Lawyers found that 62% of its members reported an increase in clients seeking prenups, and 51% specifically noted a rise in requests from millennials, with only 2% seeing a decline from that group. “Couples are getting married at later ages these days and are consequently entering their relationships with more to protect,” said Joslin Davis, then-president of the AAML, in the organization’s own release of the findings.
That explanation, delayed marriage plus accumulated assets, made sense for millennials a decade ago. It fits Gen Z less neatly, since many are signing prenups well before hitting the asset-accumulation stage that used to justify one. The same AAML survey found the most common items couples wanted covered were protection of separate property (78%), alimony or spousal maintenance (74%), and division of property acquired during the marriage (68%). Those categories don’t require wealth. They require two people who want clarity about who owes what and who owns what, regardless of how much or how little is actually on the table.
Even singles with nothing to protect yet are already on board
New data suggests the openness to prenups starts even before a couple gets engaged. In Match and the Kinsey Institute’s 15th annual Singles in America study, released this month, 70% of singles said they’re open to a prenup or similar financial agreement before marriage, and 71% said being upfront about money builds trust in a relationship. That framing is the real break from how prenups used to be discussed. They’re not being pitched, or accepted, as a hedge against a future betrayal. They’re being treated as one more conversation a couple has early, alongside where to live or whether to combine bank accounts, so nobody is guessing later.
Part of that shift tracks with how differently Gen Z enters adulthood compared to previous generations. Many are carrying student debt, freelancing or juggling multiple income streams instead of holding one stable job, and marrying later than their parents did, if they marry at all in their twenties. A prenup for a couple like that isn’t about shielding a fortune. It’s about naming, on paper, who’s responsible for existing debt, how future earnings get treated, and what happens to whatever they build together if it doesn’t work out. That’s a very different document than the one Hollywood prenups made famous.
What’s changed isn’t that young people trust each other less than previous generations did. It’s that they’ve watched divorce, debt, and financial secrecy do enough damage in the relationships around them to want the terms written down before the stakes get high, not after. A prenup used to be the paperwork of people with something to lose. Increasingly, it’s the paperwork of people who’ve simply decided not to find out the hard way.
