What Is a Prenuptial Agreement? A Plain Guide

Prenuptial agreements are often portrayed as something only celebrities and the very wealthy sign. In reality, many ordinary couples use them to bring clarity to their finances before they marry. A prenup is less about expecting failure and more about agreeing on the rules in advance.

In simple terms, a prenuptial agreement, also called a premarital agreement, is a written contract made by two people before they marry. It usually sets out how property, debts and certain financial matters will be handled if the marriage ends through divorce or death.

Why Couples Use Them

Without an agreement, state law decides how property is divided when a marriage ends. Rules vary considerably. Some states follow community property principles, while most use a system known as equitable distribution, in which courts divide marital property in a way they consider fair.

A prenup lets a couple replace some of those default rules with terms they choose. People commonly use them to protect a family business, preserve assets they owned before marriage, plan for children from a previous relationship or clarify responsibility for significant debts.

What a Prenup Can Cover

Prenuptial agreements typically address the ownership and division of property, including assets acquired before and during the marriage. They can also deal with responsibility for debts, rights to a business, and how property passes at death.

Many agreements address spousal support, sometimes called alimony. Courts in many states allow limits on spousal support, although some will refuse to enforce a waiver that would leave a spouse in serious hardship or dependent on public assistance.

What It Usually Cannot Cover

Courts generally will not enforce prenup terms that decide child custody or limit child support in a way that harms a child. Those questions are decided based on the best interests of the child at the time. Terms that are illegal or that encourage divorce may also be struck down.

Making a Valid Agreement

Requirements depend on state law, but several principles appear widely. Many states have adopted some version of the Uniform Premarital Agreement Act or the newer Uniform Premarital and Marital Agreements Act, which set out common standards.

Key Requirements

A prenup must be in writing and signed by both parties. Each person should enter it voluntarily, without pressure or coercion. Courts also look for fair disclosure of each party's property, income and debts, so that nobody signs without understanding what is at stake.

Timing matters. Agreements presented days before a wedding can invite claims of pressure. Giving both sides time to review the terms, ideally with their own separate lawyers, makes an agreement much harder to challenge later.

When Courts Enforce a Prenup

Courts generally enforce valid prenuptial agreements as contracts. However, a spouse may challenge an agreement by showing, for example, that they signed involuntarily, that the other party hid important financial information, or that the terms were unconscionable, meaning grossly unfair.

Some states also look at whether enforcing the agreement would be unfair given circumstances at the time of divorce. Because the standards differ, an agreement that holds up in one state could face more scrutiny in another.

Many agreements include a choice of law clause naming which state's law will apply. Couples who move during the marriage may find that clause becomes important, which is one more reason to draft carefully and review the agreement if circumstances change significantly.

Postnuptial Agreements

Couples who are already married can make a similar contract, known as a postnuptial agreement. These are increasingly common, but some courts examine them more closely because spouses already owe each other duties of fairness and good faith.

The Bottom Line

A prenuptial agreement is a tool for planning, not a prediction. It allows a couple to discuss money openly, protect specific interests and reduce uncertainty if the marriage ends.

Because the rules turn on state law and individual circumstances, anyone considering a prenup should speak with a qualified family law attorney, and each partner should have independent advice. Court Magazine will keep explaining the legal ideas that shape everyday life.
