Prenuptial & postnuptial agreements
A prenuptial agreement is a contract two people sign before marriage that defines how property, debt, and support will be handled if the marriage ends, whether by divorce or death. A postnuptial agreement is the same contract signed after the wedding. That’s the whole difference: timing.
Now let’s deal with the reputation problem, because these agreements have one. People hear “prenup” and picture cold feet in contract form. Here’s what we’ve actually watched across hundreds of these agreements: the couples who negotiate one have the most honest money conversation of their relationship, months before the wedding, with structure and counsel keeping it fair. The couples who skip it often have that same conversation eventually. Just angrier, and in front of a judge.
A marital agreement isn’t a bet against your marriage. It’s an agreement about fairness, written while you like each other. That’s the best drafting condition there is.
Prenup vs. postnup: does timing matter?
Legally, yes, somewhat. Both are enforceable in the states where we practice when done properly, but courts tend to look at postnuptial agreements more closely. The reasoning is simple: before the wedding, either person can walk away. After it, the leverage is different, so the fairness and disclosure standards get extra scrutiny. The practical translation: a postnup is absolutely worth doing, and it’s worth doing carefully.
Practically, the difference is momentum. Before the wedding there’s a natural deadline and a natural occasion for the conversation. After it, there usually needs to be a trigger: a business launch, an inheritance, a career change, a rough patch the couple worked through and wants to armor against. All good reasons. The paper works the same.
Why couples actually sign these
Forget the tabloid version. Here’s who’s really across the table from us:
The business owner or professional.
A practice, a company, a partnership stake. Without an agreement, a divorce can put the business itself into play: valuation fights, discovery into company records, a buyout that starves the operation, sometimes pressure on partners and employees who have nothing to do with the marriage. An agreement can take the business off the battlefield entirely. If you own equity in anything, this is reason enough.
The one with family money coming.
Inheritances and gifts generally start as separate property, but separate property is a leaky bucket. Deposit an inheritance into the joint account, use it on the marital home, let it appreciate with marital effort, and its character can blur. An agreement seals the bucket, and spares your parents the awkward project of estate-planning around your marriage.
The second marriage.
Both spouses come in with assets, and often with children who should inherit them. A marital agreement working alongside an estate plan is how you take care of your spouse and keep your commitments to your kids. Without it, those two goals can collide badly.
The couple with lopsided debt.
Student loans, business debt, tax exposure. An agreement can wall one spouse’s liabilities off from the other’s assets and future.
The couple who just wants to decide for themselves.
Marry without an agreement and your state’s default rules are your agreement. Some couples read those defaults and shrug. Others would rather write their own. That preference alone is a legitimate reason.
What can a marital agreement cover?
A lot. How property owned before the marriage is treated. How property acquired during the marriage gets classified and divided. What happens to a business and its appreciation. How inheritances and gifts are handled. Responsibility for debts. Whether and how spousal maintenance would work, within limits some states place on support waivers. Coordination with estate plans, including what each spouse waives or retains at death.
What it can’t cover: child custody and child support. Courts decide children’s issues based on the children’s interests at the time, and no contract signed years earlier binds that. Any agreement that pretends otherwise has a hole in it.
What makes these agreements enforceable, and what breaks them
This is the section to read twice, because an unenforceable marital agreement is worse than none. It’s false confidence with a signature on it.
The pillars, in every state we practice, look similar even though the specific standards vary:
Full financial disclosure.
Both parties lay out their assets, debts, and income, completely. Hiding the ball, even sloppily, is the classic way agreements die in court a decade later.
Independent counsel.
Each party should have their own lawyer. Not one lawyer “for the couple.” Courts weigh this heavily, and beyond enforceability, it’s what makes the deal actually fair.
No pressure, no ambush.
An agreement presented days before the wedding, sign-or-else, is a litigation invitation. Start months out. Time is what separates a negotiation from an ultimatum.
Basic fairness.
Standards differ by state, and terms don’t have to be equal. But agreements that leave one spouse destitute invite courts to look for reasons not to enforce them.
Do it right and these agreements are strong.
Do it fast and cheap, and you’ve prepaid for a second lawsuit inside your divorce.
Can an existing agreement be changed?
Yes. Marital agreements can be amended or replaced by the same process that created them: written, disclosed, and with both parties represented. Lives change; agreements should keep up. The prenup from 2015 doesn’t know about the company you started in 2022. A periodic review, the same way you’d review an estate plan, is smart practice.
Straight answers.
Are marital agreements only for wealthy people?
No, and honestly the middle of the wealth spectrum may need them most. A wealthy person can absorb a bad property division. A person whose entire net worth is one practice, one house, or one pension cannot. The question isn’t how much you have. It’s how much of what you have you can afford to put at risk of a default rule.
Can an agreement protect my business or practice?
Yes, and this is among the strongest reasons to have one. It can classify the business and its future growth, fix a valuation method in advance, and keep the company’s books out of a divorce. Ask any business owner who’s been through discovery without one.
Are these agreements actually enforceable?
When properly done, yes, in every state we practice, though the standards and limits vary by state. The failures are almost always self-inflicted: missing disclosure, no independent counsel, last-minute signing.
Do we both really need our own attorney?
Yes. It protects the agreement and it protects each of you. One-lawyer agreements are where enforceability challenges go to feast.
When should we start the conversation?
For a prenup, the moment engagement is real, and no later than a few months before the wedding. For a postnup, whenever the reason arises. The calendar is a fairness issue, not just a convenience one.
How does an agreement prevent future disputes?
By answering the expensive questions in advance: what’s separate, what’s marital, what the business is worth and how it would be valued, what support looks like. Most divorce litigation is a fight about exactly those questions. An agreement is the fight, held early, at one percent of the price, with love in the room instead of lawyers on the clock.
Let’s talk
Whether you’re engaged, married, or somewhere in the gray in between, we’ll tell you honestly whether an agreement makes sense for you, what it should cover, and how to raise it with your partner without making it weird. That last part matters more than people admit.
