For decades, the prenuptial agreement carried a stigma: it was the tool of a wealthy, older spouse trying to shield a fortune from a younger partner before the wedding even happened. Bring it up at the wrong dinner table and you’d get raised eyebrows, as if planning for divorce was the same as expecting it.

That reputation is fading fast, and the numbers back it up. Surveys tracking younger generations have found that a majority of engaged and married millennials and Gen Z adults have now signed a prenup, a share that has climbed sharply over just the past few years. A growing number of engaged couples – many with modest savings, rented apartments, and no inheritance in sight – are treating a prenup less like a doomsday contract and more like a financial planning tool they wish more people used sooner.

Part of the shift seems generational. Couples who watched friends, siblings, or parents go through messy, expensive divorces are less interested in leaving major financial questions to chance – or to a courtroom. Instead, they’d rather have an honest conversation up front, while everyone still likes each other, about what happens to their money if the marriage doesn’t work out.

What a Prenup Actually Does

At its core, a prenuptial agreement is a legal document signed before marriage that spells out how a couple will divide assets, debts, and spousal support if the marriage ends in divorce or death. Many couples also fold it into broader estate planning – for example, outlining what happens financially if one spouse becomes incapacitated and can no longer manage their own affairs.

One family law attorney compares it to a business partnership agreement: no reasonable person would go into business with someone without first agreeing on how expenses, labor, and profits get split. A prenup does the same work for a marriage, laying out a shared roadmap before the relationship’s financial stakes get complicated. It’s less about distrust and more about clarity – replacing assumptions about “what’s fair” with terms both people actually agreed to. A prenup pitched as “protecting my stuff from you” invites conflict; one pitched as “let’s decide together how we’d handle the hard scenarios” tends to land very differently.

Why Couples Without Big Money Are Signing On

The old assumption – that prenups only matter once there’s a fortune to protect – doesn’t hold up the way it used to. Financial professionals point to several areas where a prenup can matter regardless of how much a couple currently has in the bank right now. The common thread: it’s not about what you own on your wedding day, it’s about what you’re likely to accumulate, sacrifice, or owe over the decades that follow.

Investments and equity. Stock options, a growing 401(k), or an early stake in a company may not amount to much today, but they can compound into significant wealth over the course of a marriage – especially for people early in tech or finance careers, where equity compensation can eventually dwarf salary. Younger couples are increasingly using prenups to address not just what they currently own, but how future growth in those accounts should be handled if the marriage ends.

Career sacrifices for caregiving. When one partner steps back from work – to raise children, care for an aging parent, or support the other spouse’s career – they don’t just lose a paycheck for a year or two. They lose raises, promotions, and long-term earning potential that compounds over a career and is difficult to get back later. A prenup can build in financial protections that reflect the real economic cost of stepping out of the workforce, rather than leaving it to be argued after the fact.

Existing debt. Student loans, credit card balances, and medical debt brought into a marriage don’t have to become shared burdens just because a couple says “I do.” Depending on state law, a prenup can specify that debt taken on before the wedding stays the responsibility of the person who incurred it, protecting a partner with little or no debt from inheriting a spouse’s financial history.

Pets. It sounds minor until it isn’t. Pets have become a genuinely contested category in modern prenups, especially among couples who treat a dog or cat as something closer to a family member than property. More couples are specifying who “owns” a pet acquired before marriage, how custody would work if the couple splits, and how ongoing costs like food and vet bills get split. Enforcement varies significantly by state, so it’s worth understanding how your local courts tend to treat these clauses.

Reproductive material. Questions around embryos are showing up in prenup conversations more frequently. These provisions can address what happens to frozen embryos if the couple divorces, an area where the law is still evolving and varies widely by state.

How to Start the Conversation

For many couples, the hardest part of getting a prenup isn’t the legal process – it’s bringing it up in the first place without it feeling like an accusation. A few things tend to make the conversation go more smoothly:

• Start early. Waiting until a month before the wedding to raise it puts unnecessary pressure on both partners and can make the agreement look rushed or coerced if it’s ever challenged later. Most attorneys recommend starting the process several months out.
• Frame it as mutual, not one-sided. A prenup that only protects one partner’s assets is more likely to create resentment – and, in some cases, is more likely to be challenged in court. Approaching it as a joint planning exercise tends to produce a fairer document and a smoother process.
• Get full financial transparency on the table. A prenup is also a forcing function for a conversation many couples put off – laying out debts, income, assets, and spending habits in full. Going through that process honestly, even if it’s uncomfortable, tends to prevent bigger financial surprises later in the marriage.
• Treat it as a living document. Life circumstances change – a new job, a child, an inheritance, a move to a new state. Some couples build in a review clause so they can revisit the agreement periodically rather than treating it as fixed forever.

The Bottom Line

A prenup isn’t a bet against your marriage. It’s closer to an insurance policy – something you hope never to need, but that can spare both partners a devastating legal and financial mess if things don’t go as planned. It won’t cover every possible scenario, and it’s not a substitute for an honest conversation about money before you get married – if anything, it forces that conversation to happen. For a growing share of engaged couples, the peace of mind it provides is worth both the upfront cost and the sometimes-awkward process it takes to get there.
