A prenuptial agreement lets a couple decide in advance who keeps what if the marriage ends. It protects property, inheritances, and businesses, but it costs money, can strain trust, and fails in court if it is rushed or unfair.
Prenups are now common, with 53% of engaged or married Gen Z and Millennial adults having signed one.
What is a Prenuptial Agreement?
A prenuptial agreement is a legal contract between two people who plan to marry. It sets out who owns what, who owes what, and how property and support are handled if the marriage ends by divorce or death. It takes effect on the wedding day.
Marriage is already a contract. The state writes most of its terms: how property is divided, whether spousal support is paid, and what a surviving spouse inherits. A prenup lets the couple replace some of those default rules with their own.
A prenup can cover property division, separate assets and debts, spousal support, life insurance, Wills, and inheritances. It cannot decide child custody, visitation, or child support. Courts keep that power to protect the child.
Prenuptial Agreements Pros And Cons
The realization of a prenuptial agreement has numerous advantages, but it also has some disadvantages.
Let’s see next a brief exposition and summary of the main positive points and also of the main negative points of making a prenuptial agreement.
Advantages of a Prenuptial Agreement
The biggest advantage is certainty. A prenup tells both partners, in writing, what stays separate and what is shared, so a divorce does not turn into a guessing game decided by a judge.
Here is what a prenup can do for you:
- Protect wealth you bring into the marriage. Savings, a house, retirement accounts, and investments you own before the wedding can stay yours.
- Secure inheritance for your children. If you have children from a past relationship, a prenup can keep specific assets earmarked for them.
- Limit exposure to your partner’s debts. A prenup can state that each spouse stays responsible for the debts they bring in, such as student loans. It binds the spouses to each other. It does not bind lenders, who can still pursue joint accounts and loans you co signed.
- Keep a business under one owner. 32% of respondents named business protection as a reason. A prenup can state that the company, and its growth in value, is not shared with a future spouse.
- Set spousal support terms in advance. 29% used a prenup to address alimony.
- Cover newer assets. Couples now list cryptocurrency, online businesses, and other digital holdings, which are easy to overlook and hard to value later.
- Force an honest money conversation. Writing the agreement means both people disclose income, debts, and goals before the wedding.
In the nine community property states, such as California and Texas, a prenup can also opt out of the rule that treats most income earned during marriage as owned half by each spouse.

Disadvantages of a Prenuptial Agreement
The main disadvantages are emotional and financial. Raising a prenup can feel like planning for failure, and a poorly handled conversation can leave one partner hurt before the marriage starts.
Couples who sign a prenup may simply differ from couples who do not. Many have more assets, previous marriages, or more cautious personalities, so the survey cannot show that the agreement itself weakens a marriage.
Other disadvantages to weigh:
- Cost. Each partner should have their own lawyer. Family law attorneys charge an average of $344 per hour. As an illustration, ten hours of work per side adds up to $6,880 for the couple.
- Lost rights. A spouse who gives up support or a share of property can be left with little after years of unpaid work at home or in the other partner’s business.
- Unfair outcomes. A prenup written for a marriage at age 28 may look very different after twenty years, three children, and a career change.
- Risk of being thrown out. A court can refuse to enforce terms that were hidden, pressured, or grossly one sided.
- Limits on topics. Daily chores, holidays, and other lifestyle promises are not enforceable in most courts, and child related terms are ignored.
What Changed in Prenup Law Between 2023 and 2026
Prenup law is set by each state, and several states rewrote or added rules in the past three years. The changes below apply to agreements signed after each effective date.
- West Virginia (July 1, 2023): a new act based on the Uniform Premarital Agreement Act (UPAA) applies to agreements signed on or after this date.
- Ohio (March 23, 2023): postnuptial agreements became legal.
- Minnesota (August 1, 2024): a rewritten statute applies to agreements signed on or after this date. It requires two witnesses and an acknowledgment, and it does not allow couples to waive financial disclosure.
- New York (2025): in JM v. GV, 225 N.Y.S.3d 859, a court struck a spousal maintenance waiver because the husband had no lawyer and did not understand what he gave up. The court said a valid waiver should state both incomes and the actual support calculation. The property waiver in the same prenup was upheld.
- Arizona (2026): a new postnuptial provision, A.R.S. 25-202.01, was added.
The New York ruling carries a lesson for every state. Signing without a lawyer, or without a clear statement of what is being given up, is the fastest way to lose a waiver in court.
What Makes a Prenup Enforceable?
A prenup is enforceable when it is in writing, signed voluntarily, supported by honest financial disclosure, and fair enough that a court does not find it unconscionable. Unconscionable means so one sided that enforcing it would shock the court.
These are the standards courts apply most often:
| Requirement | What courts look for | Example |
|---|---|---|
| Written and signed | Most states require a signed writing | Georgia needs two witnesses, one a notary |
| Voluntary | No pressure, threats, or deadline tricks | A Missouri court found a prenup handed over the night before the wedding unconscionable (Potts, 2010) |
| Disclosure | A fair list of assets, debts, and income | Under the UPMAA, a signed waiver can replace disclosure, but Minnesota bars waivers |
| Independent lawyer | Each side had a chance to consult counsel | In Colorado and North Dakota, lack of access to a lawyer is a ground against enforcement |
| Timing | Enough days to read and think | California requires at least 7 calendar days between receiving the final agreement and signing |
Practical advice follows from this. Start at least two to three months before the wedding, hire separate lawyers, exchange full financial statements, and keep copies of everything that was shared.
When a Prenup Makes the Most Sense
A prenup is most useful when the two partners expect to be financially unequal, or when one of them has something specific to protect. Couples with matching assets and no children may gain little.
Consider a prenup if any of these apply:
- One partner owns a business or a share in one.
- One or both partners have children from an earlier relationship.
- One partner expects a large inheritance or family gift.
- There is a large gap in income, savings, or debt.
- One partner plans to leave work or cut hours to raise children.
- Either partner is marrying for a second or third time.
- Either partner holds cryptocurrency or other digital assets.
Conclusion
A prenup is a tool for certainty. It works best for couples with a business, an inheritance, children from earlier relationships, or a large gap in assets. It works poorly when it is rushed, hidden, or written for only one side.
The strongest agreements share three traits. Both partners disclose everything, both have their own lawyers, and both sign well before the wedding.
Prenup law differs by state and keeps changing.
