What a Peer-Reviewed Study Found About Changing Minds on Prenups

If a partner's hesitation about a prenup feels like a wall, it helps to know what is behind it. Often it is not the money, the paperwork, or the timing. It is a feeling that a prenup means something unromantic about the relationship. That feeling is common, and new research suggests it is more changeable than most people assume. A 2026 study in the journal Law and Human Behavior found that beliefs about prenups predicted people's attitudes more strongly than demographic factors like age and education. In other words, what someone believes a prenup means matters more than who they are on paper.

That is a hopeful finding. Beliefs can shift when they meet good information. Let's walk through what the study found and what it means for a real conversation with your partner.

What did the prenup attitudes study actually find?

The study, titled "Attitudes and Intentions Toward Prenuptial Marriage Contracts," was published in Law and Human Behavior, a journal of the American Psychological Association, in 2026. It was conducted by researchers Nicolyn Charlot and Samantha Joel of the University of Western Ontario, along with Claire Houston of Western Law. The researchers ran two online-sample studies to figure out what predicts how people feel about prenups.

The headline result: a person's beliefs about prenups, such as whether they seem unromantic or whether they seem practical, predicted attitudes far better than age, education, income, or how long a relationship had lasted. Demographics turned out to be weak predictors. Beliefs turned out to be strong ones.

This is a different way of thinking about the question. When a partner resists the idea of a prenup, the instinct is often to assume the resistance is tied to something fixed: their upbringing, their income, their stage of life. The research points somewhere else. What tends to be driving the reaction is a belief about what the document represents, and beliefs are not fixed. The study's procedures and de-identified data are openly posted on the Open Science Framework, which is worth noting because it lets other researchers check the work.

One caution before we go further. The authors are based in Canada and used online samples, so this is best read as general research on public perceptions rather than a U.S.-specific finding. The pattern it describes, though, will feel familiar to a lot of American couples.

Why do beliefs matter more than age or income?

Think about how the "prenups are unromantic" idea usually forms. Most people absorb it long before they ever read what a prenup does or talk to anyone who has signed one. It arrives as a cultural assumption, picked up from movies, offhand comments, and the vague sense that planning for the unhappy case is a bad omen for the happy one. By the time a couple is engaged, the belief is already sitting there, fully formed, without much fact behind it.

That is why demographics predict so little. A 34-year-old and a 44-year-old can hold the exact same belief, and it is the belief, not the birthday, that shapes how each one reacts. Someone who sees a prenup as a hedge against the marriage failing will feel one way. Someone who sees it as a planning tool, a way to talk openly about money and shared goals before the wedding, will feel another way. Same document, opposite emotional response, and the difference lives entirely in the framing.

We have written before about where the "unromantic" belief comes from and why a prenup is not a red flag. The research adds a useful piece to that picture: because the belief is doing the heavy lifting, the belief is where a conversation has room to move.

Can accurate information really change how someone feels about a prenup?

This is where the study gets practical. Beyond measuring what predicts attitudes, the researchers tested an informational intervention, which is a plain way of saying they gave people accurate facts about prenups and watched whether their views changed. They did.

The study found that a simple informational intervention was sufficient to shift attitudes and intentions toward prenuptial agreements in a more positive direction. People who received accurate information reported warmer attitudes and stronger intentions than they had before. The belief softened when it met the facts.

It is worth being precise about what this does and does not show. The study measured attitudes and intentions, meaning how people felt and what they said they were inclined to do. It did not track whether those people went on to sign a prenup, and it says nothing about marriage or divorce outcomes. A prenup does not guarantee any outcome, and this research makes no claim about behavior in the real world. What it shows is narrower and still useful: when the barrier is a belief built on assumptions, accurate information is enough to move it.

That maps onto a lot of couples' experience. If your partner's hesitation rests on the idea that a prenup plans for failure, learning what a prenup does, that it can strengthen rather than strain a relationship, tends to do more than any amount of persuasion. This is the emotional terrain we cover in more depth in the psychology of getting a prenup.

What does this mean for the prenup conversation with your partner?

Here is the takeaway, translated into something you can use. If a partner is hesitant, the productive move is to share accurate information, not to apply pressure. The research suggests the second approach tends to backfire and the first tends to work, because the thing standing in the way is usually a belief rather than a hard objection.

A few things follow from that.

First, treat the hesitation with respect. The "unromantic" feeling is common and worth taking seriously, not something to argue away. The study found it is widespread, which means your partner is in good company, and it found it is changeable, which means the conversation is worth having.

Second, lead with what a prenup does rather than what it protects against. A prenup is a planning tool that helps a couple talk openly about money, financial goals, and how they want to handle shared and separate assets. Framed that way, it reads less like a bet against the marriage and more like a shared decision made with full information.

Third, give it time and give it facts. The intervention that worked in the study was informational, not emotional. That is oddly freeing. You do not have to win an argument. You have to close a gap between what your partner believes and what is true. Our guide on how to bring up a prenup with your partner walks through how to open that conversation without it feeling like a confrontation.

It also helps to know the ground is solid legally. The Uniform Premarital Agreement Act and its successor, the Uniform Premarital and Marital Agreements Act, have been adopted by 29 states plus the District of Columbia, according to the Uniform Law Commission. Prenups are a well-established, widely recognized part of family law, not a fringe arrangement.

How do these findings line up with what Americans actually think now?

The study describes a mechanism. National polling shows that mechanism playing out at scale. Attitudes toward prenups have shifted meaningfully in recent years.

A 2023 Harris Poll reported by Axios found that roughly 50% of U.S. adults said they support the use of prenups, up from 42% the year before. That is a notable move in a single year, and it points in the same direction as the study: as information spreads and the idea becomes more familiar, support grows. We cover this shift in more detail in our post on the percentage of people open to a prenup.

Adoption is following attitudes, especially among younger adults. A separate Harris Poll conducted for Bloomberg and released in July 2026 found that 53% of engaged or married Americans under 45 said they had signed a prenup. It is worth keeping these two numbers distinct: one measures how people feel about prenups in general, the other measures how many younger adults have actually signed one. They come from different surveys and answer different questions. Read together, they describe a generation that is both warmer toward prenups and more likely to have one.

A note on all of these figures: survey numbers reflect self-reported attitudes and behavior at a point in time, and they can shift as attitudes keep moving.

Frequently asked questions

What did the 2026 prenup attitudes study find?

A study in the APA journal Law and Human Behavior found that beliefs about prenups, such as whether they seem unromantic or practical, predicted people's attitudes far better than age, education, income, or relationship length. It also found that giving people accurate information shifted their attitudes and intentions in a more positive direction.

Who conducted the prenup attitudes study?

The study was conducted by researchers Nicolyn Charlot, Samantha Joel, and Claire Houston, and published in Law and Human Behavior in 2026. Charlot and Joel are affiliated with the University of Western Ontario's psychology department, and Houston is with Western Law. Their study materials are openly posted on the Open Science Framework.

Can you change someone's mind about getting a prenup?

Research suggests you can. The 2026 study found that a simple informational intervention, giving people accurate facts about prenups, was enough to shift attitudes and intentions. It implies that sharing clear information tends to work better than pressure when a partner is hesitant, because the barrier is often a belief rather than a fixed objection.

Why do people think prenups are unromantic?

The belief tends to predate most people's actual knowledge of what a prenup does. Research identifies "unromantic" as one of the underlying beliefs that shapes attitudes, and it found that accurate information can soften that belief. That suggests the perception often rests on assumptions rather than facts about how prenups work.

Are prenups becoming more accepted?

Yes. A 2023 Harris Poll reported by Axios found roughly 50% of U.S. adults said they support prenups, up from 42% the year before. Attitudes have shifted quickly in recent years, especially among younger adults, and adoption among people under 45 has risen alongside that shift.

How First helps

If a conversation about a prenup has stalled on a feeling rather than a fact, this research suggests good information is what moves it. First was built to make that information easy to share: a clear, plain-language process, with access to independent attorney review when a couple wants it. No PDFs, no hourly rates, no back and forth with attorneys before you are ready. You can learn how a prenup with First works whenever you and your partner are ready to look together.

Methodology

The study figures are drawn from Charlot, Joel and Houston, "Attitudes and Intentions Toward Prenuptial Marriage Contracts," published in Law and Human Behavior in 2026, based on two online-sample studies (Study 1 mean age 30.4; Study 2 mean age 43.9) that measured predictors of prenup attitudes and tested an informational intervention. The study's procedures and de-identified data are openly posted on the Open Science Framework. National attitude and adoption figures are drawn from Harris Poll surveys of U.S. adults (2023, reported by Axios; and May 2026, conducted for Bloomberg).
