If You Don't Have a Prenup, the Government Already Wrote One for You

What actually happens if you don't have a prenup?

If you don't have a prenup, your state's default divorce laws automatically become the contract that decides how your property, debt, and income are divided if the marriage ends.

People talk about 'getting a prenup' as if the alternative is having no agreement at all. There's no such thing. Every married couple has a prenup — most just didn't write it. When you sign a marriage license, you're also opting into a thick book of rules your state has already written about who owns what, who owes what, and who pays whom if you split up.

Those rules reach the most consequential parts of your life together: the home you buy, the business you build, the retirement you save, the support one of you might pay the other for years. You didn't negotiate any of it. You inherited it the moment you said 'I do.'

The DMV test: would you let a stranger write your rules?

Almost no one would hand a government clerk authority over their personal relationship — yet marrying without a prenup does exactly that.

Here's a quick way to feel the problem. Imagine walking into the Department of Motor Vehicles, sliding a form across the counter, and saying: 'You decide. Whatever the government thinks is fair for my marriage, my money, and my future — that's what I want.' No one would do that. It sounds absurd.

But that is the practical effect of marrying without a prenup. You're delegating the terms of your most important relationship to whatever your state legislature happened to decide was 'best' — for everyone, in the abstract, with no idea who you are or what actually matters to you and your partner.

I don't think anyone would walk into the DMV and say, 'You're in charge of my intimate relationship rules.' But if you don't have a prenup, that's exactly the deal you signed.

The only contract outsiders can rewrite without your consent

A marriage governed by default state law is the only major contract you'll ever 'sign' whose terms can be changed later by people outside the relationship — without asking you.

Think about every other contract in your life. A lease, a mortgage, a car loan, a business agreement — once it's signed, the terms are the terms. The other side can't quietly rewrite them next year because a committee voted to. You'd have to agree.

Default marriage law doesn't work that way. Legislatures amend it. Courts reinterpret it. The rules that apply to your divorce are generally the rules in force when you divorce — not the ones that existed when you married. So the agreement you 'signed' can be edited, by strangers, with or without your consent, and you have no standing to object.

The alimony-formula problem: rules can change after you've 'already signed up'

States increasingly use fixed formulas to calculate alimony, and a new formula can apply to a marriage you entered years earlier under entirely different assumptions.

Say your state adopts a formula that sets spousal support based on income and the length of the marriage. Maybe you think the result is fair; maybe you think it's wildly unfair. It doesn't matter. If you're already married, you already signed up — under rules that may not even have existed when you walked down the aisle.

That's the quiet danger of the default. You're not just bound by today's law; you're bound by whatever the law becomes, applied to a decision you made under different terms. A prenup freezes your own deal in place so it can't be rewritten out from under you.

Most people learn the rules across the table from a divorce lawyer

The vast majority of couples never read their state's default marital rules — they discover them only in a lawyer's office, once the marriage is already over.

In 25 years of divorce practice, I've watched the same scene play out again and again. Smart, careful people — the kind who read every line of a phone contract — sit down across from me and learn, for the first time, what their marriage actually said about their money. By then it isn't a negotiation. It's a reading of the will.

That's the part that should bother you most: the terms were knowable the entire time. You could have read them, changed them, and chosen your own instead. Almost no one does, because no one hands them to you. A prenup is simply the act of reading the contract before you sign it.

How to write your own rules instead

A prenuptial agreement replaces your state's default terms with terms you and your partner actually choose — and you can create one online, designed by an attorney, for a flat $599.

A prenup isn't about betting against your marriage. It's about being the author of it instead of a passive party to whatever the state decides. You choose how you'd handle property, debt, and support — together, calmly, before there's any conflict — rather than leaving it to a formula and a judge who have never met you.

Trusted Prenup was built to make that straightforward. A guided questionnaire captures your situation, we assemble an agreement built to meet your state's exact requirements, and you review, sign, and notarize online. A traditional attorney can run five figures; this is a flat $599. If you want to see how your own state's default rules stack up against a prenup you write yourself, start with the state guides linked below.
