There is no such thing as no prenup. Every married couple has one. The only question is whether the two of you wrote it or your state wrote it for you.
Key Takeaways
- Choosing “no prenup” is not choosing nothing. It is accepting the default rules your state already wrote, which govern what happens to income, property, and debt if the marriage ends.
- The real comparison is between an agreement two people read, discussed, and negotiated, and a set of rules neither of them has ever read.
- Without an agreement, a judge applies those default rules and decides. With one, the couple decides in advance, at the point when they are aligned rather than in conflict.
- The default rules do not keep separate property separate on their own. Ordinary financial behavior during a marriage can pull property one spouse brought in years earlier into the marital estate.
- The honest cost comparison is not the price of an agreement against zero. It is a fixed, known cost now against an open-ended one later, decided under rules the couple did not choose.
The Choice Is Not Between an Agreement and No Agreement
Standing in front of everyone, saying “I do,” and signing a marriage license does more than start a marriage. It signs the couple up for an entire body of state law governing the legal status of their finances during the marriage and after it. That body of law is a prenuptial agreement in every practical sense. It says who owns what, what counts as shared, and how it all gets divided if the marriage ends.
So anyone getting married has a prenup by default. Very few people have read it. Most of it was drafted generations ago, built on assumptions about marriage, earning, and caretaking that have little to do with how couples actually organize their lives now. It has been amended around the edges for a century and a half, and the foundation still shows its age.
That is what reframes this decision. Weighing a prenup against having no agreement is weighing something against nothing, and the choice looks obvious. Weighing an agreement two people wrote together against one written by strangers before either of them was born is a different question with a different answer.
What the Default Rules Actually Do
The specifics vary by state, and the variation is real. Most states divide marital property by equitable distribution, where a judge weighs a list of factors and decides what is fair. A smaller group are community property states, where property acquired during the marriage is presumed to belong to both spouses. Some states let a court revisit an agreement’s fairness years later. Others assess it only at signing. The state pages go into what applies where you live.
What every default has in common is more important than how they differ. None of them was written with a particular couple in mind. Under equitable distribution in particular, a judge holds real discretion over how much weight to give each spouse’s contributions, conduct, and earning capacity. That discretion is what turns a divorce into a contest. Two people arguing about who contributed what, to a judge who met them both an hour ago, is the expensive version of this process, and it is the version the default rules produce.
The Default Does Not Keep Separate Property Separate
This is where the “we do not need one, we keep everything separate” reasoning breaks down. Once married, the income each spouse earns is marital money. That single fact does more work than people expect.
Take a spouse who owns a condo before the wedding and keeps paying the mortgage from their own checking account, funded by their own salary, specifically so the other spouse has no claim to it. Every one of those payments is made with marital money. The result is a marital interest in that condo, created entirely by the owner, and the other spouse never has to contribute a dollar for it to happen. The same logic reaches the appreciation and equity that build up after the wedding date.
The insidious part is that the behavior people adopt to keep things separate is frequently the behavior that commingles. Separate titling and separate accounts feel like protection and are not. Keeping premarital assets genuinely separate takes an agreement that says so, in writing, before the pattern starts.
What Changes With an Agreement Is Mostly the Timing
The practical difference between having an agreement and not having one is when the financial conversation happens.
Without one, it happens at the worst possible moment. Two people who are hurt, angry, and represented by opposing counsel try to sort out fifteen years of intertwined finances while a court schedule pushes them along. Nobody is at their most generous or their most reasonable. The conversation still happens. It just happens under conditions designed to make it hard.
With an agreement, the same conversation happens while both people still want good outcomes for each other. What comes into the marriage, how earnings will be treated, what happens if one person steps back from a career to raise children, how debt will be handled. Couples who go through this process routinely report that the conversation itself was the valuable part, and that is not incidental. Financial transparency practiced once tends to become a habit rather than an event, which is a large part of why prenups strengthen a marriage rather than straining it.

The Case for Skipping It, and What It Misses
Three arguments come up constantly, and each one has a real answer.
“We do not have enough for it to matter.” Assets are the smallest part of what an agreement covers. Debt, future income, a business that does not exist yet, an inheritance that has not arrived, and how a career pause gets accounted for all get decided by the default rules if nobody decides otherwise. Couples with less to divide are often the ones for whom a bad division does the most damage.
“It feels like planning to fail.” A will is not a plan to die and insurance is not a plan to crash. This is the same category of thinking, applied to the asset most couples actually build together. The agreement’s job is to make the terms of the marriage explicit while both people are choosing them freely.
“We will just be fair to each other.” Probably true, and it is not enforceable. Fairness in the abstract, without a written record of what either person meant by it, is exactly what a judge ends up defining later.
Deciding With Real Information
The decision worth making is not whether a prenup is worth it in the abstract. It is whether the default agreement already in place fits the specific two people who would otherwise be governed by it. Most couples have never read that default, which means most couples are choosing it without knowing what it says.
Reading it is the first step, and a licensed attorney who does this work can explain what the governing state’s rules would do with a particular set of finances, in one conversation, before anything gets drafted.

Frequently Asked Questions
What happens if you do not have a prenup?
Your state’s default rules apply. Those rules determine what counts as marital property, how it gets divided, and how debt and spousal support are handled. In most states, a judge applies a list of fairness factors and exercises real discretion over the outcome. The agreement exists either way; without a prenup, someone else wrote it.
Is a prenup worth it if we do not have many assets?
Often more so, not less. An agreement governs future income, debt, a business that has not started yet, an inheritance that has not arrived, and what happens if one person pauses a career. Couples early in their financial lives have the most still ahead of them to define, and the least cushion if a division goes badly.
Does getting a prenup mean you expect the marriage to fail?
No. It means the financial terms of the marriage get decided by the two people in it, at the point when they are both trying to be fair to each other, rather than by a statute neither of them has read. Couples consistently describe the process as clarifying rather than ominous.
Can we just agree to be fair to each other instead of signing something?
An informal understanding is not enforceable, and “fair” means different things to two people looking back on the same fifteen years. A prenup is the version of that agreement a court will actually honor, which is the only version that matters at the moment it is needed.
Is a prenup only useful for the person with more money?
No. A well-drafted agreement defines what happens to both people, and the spouse with less income is frequently the one better protected by written terms than by a judge’s discretion. Provisions addressing a career pause or a support arrangement generally benefit the lower-earning spouse.
Is it too late to do this if we are already married?
No. A postnuptial agreement covers the same ground after the wedding. The rules differ from prenups in some states, and in a few states the difference is significant, so this is worth a specific conversation rather than an assumption.
