Prenups and the Wealth-Transfer Generation: Why Young Couples Sign Before They're Rich

You are in your early thirties, maybe engaged, maybe close to it. You do not own a vacation home or a company. What you do have is a sense of what is coming: a parent who may leave you something one day, a grandmother's house that might pass down, a career that is still climbing, and possibly a student loan balance you would rather not share with anyone. That mix, money expected but not yet held, is where a growing number of young couples are starting their prenup conversations.

The headlines call this the "great wealth transfer," and they are not wrong that something large is underway. Cerulli Associates projects that $84.4 trillion in wealth will transfer through 2045, with roughly $72.6 trillion going to heirs. A good share of that reaches people who are young now and marrying soon. Pew Research Center has also documented that young adults today reach financial milestones later and are more likely to carry student debt than the generation before them, with the share of 25-to-29-year-olds holding student loans rising from 28% in 1992 to 43% in 2022. Planning before the wealth arrives, and before the debt complicates things, is the thread running through this trend.

Why are young couples getting prenups before they're rich?

The old story about prenups was that they were for people with something to lose today: a fortune, a business, a second marriage to protect from the first. That story misses what is driving younger couples now.

Most couples in their late twenties and thirties are not sitting on wealth. They are anticipating it. A prenup, at its core, is a way for two people to decide in advance how they want money handled, including money that has not shown up yet. That could be a future inheritance, a family gift toward a down payment, or the upside of a career that is still early. It could also be debt. For many couples the conversation is less about dividing riches and more about keeping each person's student loans their own.

This is the planning-tool reframe that First returns to often. Creating a prenup together can open an honest conversation about money, expectations, and the life you are building, long before any windfall or hardship forces the subject. If you want the broader context on how this became a generational shift, our piece on how prenups got so popular with millennials covers the wider trend.

What is the "great wealth transfer," and how does it connect to prenups?

The "great wealth transfer" is shorthand for a demographic reality. Older Americans, chiefly the silent generation and baby boomers, hold a large share of the country's accumulated wealth, and over the coming decades much of it will pass to their children and grandchildren.

The number most often cited comes from Cerulli Associates, which projects $84.4 trillion in wealth transfers through 2045, with about $72.6 trillion going to heirs and the remainder to charity. For younger couples, this reaches them mainly through two channels: inheritance and family gifts. A parent helps with a home. A grandparent's estate passes down. A family business changes hands.

Here is where it meets the prenup question. When an inheritance or gift arrives during a marriage, how it is treated depends on what the couple did beforehand and on the law of their state. Left alone, inherited money can get mixed with shared accounts until it is hard to tell what belonged to whom. A prenup lets a couple decide the treatment in advance, so a future inheritance is handled the way they both intend rather than sorted out later. For a closer look at that mechanism, see our guide on how a prenup can help you secure your inheritance.

Is it true millennials are 10 times more likely than boomers to get a prenup?

You have probably seen the line: millennials are "10 times more likely" than boomers to sign a prenup. It gets repeated across news coverage and law-firm blogs, usually without anyone tracing where it came from.

Here is what is behind it. The "10 times" figure is a comparison between two separately reported adoption rates, roughly 39% for millennials and about 4% for boomers in one survey. Divide one by the other and you land near ten. That makes it a description of a large generational gap, not a single measured statistic that someone went out and verified. It is accurate as a gap. It is misleading as a standalone number, because no study measured a "10x multiplier" directly.

The generational gap itself is well documented. A 2023 Harris Poll for Axios found that 47% of engaged or married millennials and 41% of Gen Z adults said they entered a prenup, far above older generations and well above the roughly 20% baseline for all married couples. That same polling found support for prenups rose to about 50% of U.S. adults in 2023, up from 42% the year before. It is worth keeping support (an attitude) and adoption (an action) separate, a distinction we unpack in our post on the percentage of people open to a prenup.

You will sometimes see 39% reported for millennial adoption from a different survey, which is the number behind the "10x" comparison. We use the Harris/Axios 47% and 41% figures as the primary read, since they come from a single, traceable poll. For the fuller data picture, our prenup statistics roundup collects the generational numbers in one place.

How does student debt fit into the young-couple prenup picture?

Not every young prenup is about expected riches. For plenty of couples, the more pressing concern is debt, specifically the student loans one or both partners are carrying into the marriage.

The scale is substantial. According to Pew Research Center, about one-third of U.S. adults under 30 have student loan debt, and Americans collectively owed around $1.6 trillion as of mid-2024. When two people marry with uneven loan balances, a fair question follows: if things do not work out, should one partner be on the hook for the other's education debt?

A prenup can address this directly. It can state that debt each partner brings into the marriage stays with that partner, so one spouse is not left responsible for the other's student loans in a divorce. The agreement can also designate who is responsible for debts taken on later. This is the debt-protection side of the young-couple trend, and it sits right alongside the inheritance side as the two drivers most coverage blurs together. If one of you is carrying a balance into the marriage, our piece on a prenup when one partner has debt walks through the options.

What can a prenup do with a future inheritance?

Say your parents plan to leave you their home, or a grandparent's estate is likely to pass to you someday. You do not have the money now. Can a prenup do anything about an asset you have not received?

It can. A prenup can specify that a future inheritance or family gift stays separate property rather than becoming marital property shared between spouses. The Uniform Premarital Agreement Act, the model law that has been adopted by 29 states plus the District of Columbia, recognizes agreements that define how property, including property acquired later, is treated. A well-drafted prenup is designed to keep separate property separate, so inherited funds do not quietly become joint simply because they landed in a shared account.

Why decide this before the money arrives? Because inherited funds are easy to mix. The moment an inheritance flows into a joint checking account or pays down a shared mortgage, the line between "yours" and "ours" blurs, and untangling it later can be contentious. Settling the treatment in advance is often far simpler than sorting it out after a windfall complicates things.

There is also the matter of default rules. If a couple does nothing, state law decides how assets are divided at divorce. In community property states, most assets acquired during the marriage are presumed to be owned equally. In equitable distribution states, a court divides property according to what it considers fair, and "equitable" does not always mean "equal." Couples who want certainty about how a future inheritance will be treated use a prenup to decide for themselves rather than leaving it to a judge applying their state's formula.

Frequently asked questions

Why are young couples getting prenups if they aren't wealthy yet?

Many young couples expect future wealth through inheritance, family gifts, or career growth, and a prenup lets them decide in advance how those assets are treated. Others use a prenup to keep each partner's student debt separate. The goal is planning around what is coming, not protecting what already exists.

What is the great wealth transfer?

It refers to the roughly $84.4 trillion that Cerulli Associates projects will pass from older Americans to heirs and charities through 2045, with about $72.6 trillion going to heirs. Much of it reaches younger generations through inheritance and family gifts, which is why it is reshaping how couples plan.

Are millennials 10 times more likely than boomers to get a prenup?

The "10 times" line comes from one survey comparing adoption rates, roughly 39% of millennials to about 4% of boomers. It describes a large generational gap, not a single verified multiplier. Separate Harris polling found 47% of engaged or married millennials said they entered a prenup.

Can a prenup protect an inheritance I haven't received yet?

Yes. A prenup can specify that a future inheritance or family gift stays separate property rather than becoming marital property. Deciding this before the money arrives is often simpler than sorting it out later, especially if inherited funds get mixed with shared accounts.

Does a prenup help with student loan debt?

It can. A prenup can state that debt each partner brings into the marriage stays with that partner, so one spouse is not left responsible for the other's student loans in a divorce. About one-third of U.S. adults under 30 carry student loans, per Pew Research Center.

Do I need a prenup if I don't have assets now?

Not everyone does, but a prenup can still make sense if you expect an inheritance, anticipate career growth, or want to keep debt separate. It is a planning tool for the future, not only a snapshot of today. Whether it fits depends on your situation, and our guide on a prenup without assets can help you think it through.

Methodology

These figures are drawn from Cerulli Associates' U.S. High-Net-Worth and Ultra-High-Net-Worth Markets 2021 report (wealth transfer through 2045), the Axios-Harris Poll conducted in 2023 (generational adoption and support), and Pew Research Center analyses published in 2024 (student-loan prevalence among young adults). The "10x" comparison is derived by dividing two separately reported adoption rates and is presented as a gap, not a single measured statistic.
