Prenuptial Agreements in the United States: What Couples Should Know
Prenuptial agreements in the United States are often associated with celebrities and the wealthy, but they are increasingly common for ordinary couples, especially those entering a second marriage, owning a business, or bringing significant assets or debts into the marriage. A prenup is simply a written agreement, signed before marriage, that sets out how property and finances will be handled if the marriage ends.
This guide explains what a prenup can and cannot cover, how to make one enforceable, and the mistakes that cause courts to throw them out. It is general information, not legal advice for your situation.
This article provides general legal information only. It is not legal advice, and it does not create a lawyer-client relationship. Prenuptial agreement law varies by state, so consult a licensed family law attorney about your agreement.
What a Prenup Can Cover
A prenup can define which property is separate and which is marital, protect a business or professional practice, set out how debts will be handled, decide spousal support terms within legal limits, and protect inheritances for children from a prior marriage. It can also set rules for financial management during the marriage, such as joint accounts and spending.
For couples with a business, a prenup can prevent a spouse from claiming an interest in the business on divorce, which protects partners, employees, and the company's future. For couples with children from prior relationships, it can preserve assets intended for those children.
What a Prenup Cannot Cover
A prenup cannot decide child custody or child support in advance, since courts decide those issues based on the child's best interests at the time of divorce. It cannot include terms that encourage divorce, waive rights in an unconscionable way, or cover illegal activity.
Spousal support waivers are restricted in some states, and courts may refuse to enforce a waiver that would leave a spouse dependent on public assistance. Any clause that looks punitive rather than protective is at risk of being struck down.
Requirements for an Enforceable Prenup
For a prenup to be enforceable, it generally must be in writing and signed voluntarily by both parties, with full and fair disclosure of assets, debts, and income. Both parties should have independent legal advice, and the agreement should be signed well before the wedding, not days before, when pressure and duress arguments are stronger.
Many states have adopted the Uniform Premarital Agreement Act or a similar version, which sets out these requirements. An agreement that hides assets, is signed under pressure, or is grossly one-sided at the time of signing may be invalidated.
Common Mistakes That Invalidate a Prenup
Common mistakes include failing to disclose assets, using a generic online template that does not meet state requirements, having only one lawyer for both parties, signing too close to the wedding, and never updating the agreement after major changes such as children, a business sale, or a move to another state.
Another mistake is including unenforceable clauses, such as child custody terms, which can cast doubt on the whole agreement even if the rest is valid. A lawyer can separate enforceable terms from risky ones.
When to Update or Replace a Prenup
Review your prenup after major life events: the birth of children, a significant change in wealth, starting or selling a business, an inheritance, or a move to a state with different prenup law. Couples can also sign a postnuptial agreement after marriage to update or replace an outdated prenup, subject to similar requirements.
Keeping the agreement current is especially important when the original terms no longer reflect your financial reality, since courts are more likely to enforce an agreement that remains fair over time.
How a Family Lawyer Helps
A family lawyer can draft a prenup tailored to your state, ensure full disclosure, advise each party separately, and negotiate terms that protect both sides. Independent representation for each party is one of the strongest protections against a later challenge.
A lawyer can also explain the tax and estate planning implications of your agreement and coordinate it with your wills, trusts, and beneficiary designations.
Making Your Final Decision
A prenuptial agreement is a practical financial planning tool, not a prediction of divorce. When drafted fairly, disclosed fully, and signed voluntarily with independent advice, it gives both partners clarity and protection.
If you are considering a prenup, speak with a family law attorney well before your wedding date. Early, honest planning protects both of you and lets you start your marriage with clear financial expectations.
