Talking about a prenup can feel awkward, even when a couple is otherwise comfortable discussing money, family, and the future. But in general terms, a prenuptial agreement is less about predicting divorce and more about defining expectations before legal and financial questions become emotionally charged.
A prenup is a contract signed before marriage that can address property, debts, business interests, inheritance expectations, and sometimes spousal support. Whether it “holds up” later often depends on process as much as content: timing, full financial disclosure, voluntary signing, and compliance with state law all matter a great deal. The Uniform Law Commission’s model act on premarital and marital agreements reflects that enforceability often turns on fairness-related safeguards, not just what the document says.
In this post you’ll learn what a prenup is, what it can and cannot do, why some agreements are enforced while others are challenged, and how couples often approach the process in a way that reduces later disputes. If you want a broader foundation on marital agreements generally, this more detailed guide on how courts look at disclosure, fairness, and enforceability in these agreements can help connect the bigger picture.

A prenuptial agreement, also called a premarital agreement, is a written contract made by two people before they marry. It becomes effective upon marriage and typically lays out how certain financial issues will be handled during the marriage, at divorce, or at death, depending on state law and the terms included. The American Bar Association notes that prenups often deal with property division and spousal support, while state restrictions vary on what may be included and enforced. See the ABA overview here.
In plain language, a prenup can function like a roadmap. Instead of leaving every issue to default state law, the couple creates an agreement that reflects their own circumstances. That may be especially relevant where one or both partners own a business, expect an inheritance, have children from a prior relationship, carry significant debt, or simply want more clarity about finances.
Prenups are often associated with celebrity marriages or ultra-high-net-worth families, but that stereotype is outdated. A 2023 Harris Poll conducted for Axios found that about 1 in 5 married couples reported having a prenup, and support for prenups was much broader than many people assume. Axios reported the poll results here.
People pursue prenups for many different reasons, including:
For some couples, the biggest value is not the document itself but the conversation it forces: disclosure, budgeting, values, and long-term planning. Those discussions can reveal misunderstandings while there is still time to address them thoughtfully.
