A prenuptial agreement does not have to be a bad omen for a marriage. Many people worry that asking for a prenup signals doubt about the relationship. They fear their partner will hear, “I expect this to fail.” That reaction is understandable. Money and trust are personal topics, and few couples enjoy talking about what would happen if their marriage ended.

Still, a prenup is a planning tool. Couples buy life insurance without expecting to die soon. They write wills without wishing for bad news. A prenup works in a similar way. It sets out how certain property and debts will be handled if the marriage ends through divorce or death. For some couples, talking through those details can build trust instead of eroding it.

A prenup is not right for every couple. A family law attorney can explain how marital agreements work in your state and help you and your partner decide whether one fits your situation.

Is There a Correlation Between Prenups and Divorce?

Whether prenups and divorce are connected is a question many engaged couples ask. The short answer is that no one knows for sure. There are no reliable studies or data showing that signing a prenuptial agreement makes a couple more likely to divorce. There is also no solid research showing that a prenup helps a marriage last longer.

Part of the problem is how hard this topic is to study. Couples who sign prenups are often different from couples who do not. They may be older, have more assets, own businesses, or have children from earlier relationships. Any of those factors could affect a marriage in ways that have nothing to do with the agreement itself. Separating the effects of the prenup from everything else is difficult.

How Common Are Prenuptial Agreements?

Prenuptial agreements are far more common among younger couples than many people realize. A report by First cited a Harris Poll finding that, as of May 2026, 53 percent of engaged or married Americans under age 45 said they had signed a prenup. For many younger couples, these contracts have become a regular part of planning for marriage.

Several trends may help explain this shift. Many people now marry later in life, after they have built careers, bought homes, or saved for retirement. Others may enter marriage carrying student loans or other debts. Social media discussions and changing views about money have also made the topic easier to raise. As a result, many couples now see a conversation about a prenup as a normal step before the wedding rather than a sign of trouble.

Why Consider a Prenuptial Agreement?

Couples may consider prenuptial agreements for many different reasons. One common reason is to protect property that one partner owned before the marriage. This might include a house, savings, investments, or a family heirloom. A business owner may want to keep their company separate so that a divorce does not disrupt its operations or affect business partners.

A couple’s unique circumstances can also influence the decision to sign a prenup. A person with children from a prior relationship may want to make sure certain assets will pass to those children. Someone who is expecting to receive an inheritance may want to keep family wealth within the family line. Debt is another concern. One partner may want clear terms stating that student loans or credit card debts will stay with the person who took them on.

Some couples simply value clarity. They prefer to agree on financial terms while they are on good terms, rather than leaving those decisions to a court during a painful divorce. For them, a prenup is about reducing future conflict and uncertainty.

What Do Couples Usually Include in a Prenuptial Agreement?

A prenuptial agreement usually focuses on money and property. Many agreements spell out which assets will remain separate property and which will be treated as shared marital property. They may also explain how the couple will divide property acquired during their marriage, such as a home or retirement savings.

Debts are often addressed as well. A prenup can state which partner is responsible for debts brought into the marriage and how new debts will be handled. Some agreements may cover spousal support, also called alimony, by setting an amount, limiting it, or waiving it. Rules on spousal support terms vary from state to state, and some states limit what couples can agree to.

There are also things a prenup generally cannot do. Courts typically will not enforce terms that make decisions about child custody or child support in advance. Those decisions are made based on the best interests of the child at the time of a divorce. Most states also will not enforce terms that try to control personal issues, such as household chores or how often relatives can visit.

Proper Disclosure Can Make or Break a Prenup

Proper financial disclosure is one of the most important parts of a valid prenup. Each partner generally needs to share a fair and honest picture of their income, assets, and debts before signing. The idea is simple. A person cannot make an informed choice about giving up their rights to property without knowing what that property is.

When one partner hides assets or understates their wealth, the agreement may not be valid. A court reviewing the prenup later could decide that the other partner did not have enough information to agree. In many states, that can be grounds to set aside all or part of an agreement.

Good disclosure often means more than a quick conversation. Couples may exchange written lists of assets and debts, tax returns, bank statements, and account balances. Some states allow a partner to waive full disclosure in writing, but those waivers carry their own risks. Taking time with this step can help protect both parties down the road.

Judges Can Strike Down One-Sided Prenups

A judge can invalidate a prenuptial agreement that is extremely one-sided or unfair. Courts often use the term “unconscionable” to describe an agreement that is so unbalanced that enforcing it would be unjust. For example, a prenup that leaves one spouse with almost nothing while the other keeps substantial wealth could draw close scrutiny.

The way a prenup was signed is also important. A judge may question an agreement presented the night before the wedding, when one partner felt pressured to sign. Signs of duress, fraud, or a lack of understanding can also weaken an agreement. Many couples choose to have each partner work with a separate attorney so that both sides understand the terms and have a chance to negotiate.

Standards differ across the country. Some states may look at whether an agreement was fair when it was signed. Others may consider whether enforcing an agreement would be fair at the time of divorce. A family law attorney in your state can explain how these rules apply where you live.
