- A prenup's real function is to make a stressful future decision predictable, not to predict the marriage will end.
- Most couples who benefit from one fall into at least one of five patterns: imbalanced starting position, business ownership, a prior marriage, expected inheritance, or financial unknowns.
- If none of the five apply, a prenup may still be useful but isn't necessary for most couples.
A reframe
The most common objection to a prenup is that it's unromantic. This is worth taking seriously. Signing a contract about money before saying vows does feel odd, and couples who push past that feeling often describe the conversation itself as one of the most clarifying they've had.
The reason is that a prenup forces you to talk about things most couples don't discuss until a crisis. What are your debts and assets? How do you want to handle a future inheritance? Who keeps what if this doesn't work out? Couples who answer those questions calmly before the wedding tend to have more productive financial conversations after.
With that framing, here are the five situations where a prenup is typically worth the cost.
1. You're starting from very different positions
One partner has $400,000 in savings, the other is paying off $90,000 in student debt. One partner owns a home, the other has never owned property. These imbalances don't mean anything about the health of the relationship, but they do mean that the default divorce rules in most states produce outcomes neither partner expected. A prenup lets you decide together what's fair, rather than letting a judge decide later.
2. One of you owns a business
If you own a business, your spouse may end up with an equity stake in it if you divorce, which can be disastrous if they become a co-owner with the rest of the partners or if you need to buy them out at a moment you can't afford to. A prenup clause protecting the business from becoming a marital asset is the standard solution, and it's the single most common reason founders and small business owners sign agreements.
3. You've been married before
Second marriages are the most prenup-heavy category for a reason. Children from a prior relationship, ongoing support obligations, and already-built separate assets all make the default rules a poor match. If you have children from a prior marriage, a prenup is effectively a requirement for coherent estate planning.
4. You expect a significant inheritance
Inheritances are usually treated as separate property by default, but commingling them with marital assets during the marriage is remarkably easy and can convert them into marital property without you intending it. If you expect to inherit a family home, a business interest, or a trust distribution, a prenup with specific separate-property language for inherited assets is a simple way to protect it.
5. Your financial future is genuinely unknown
Founders pre-exit. Artists or writers before a breakout. People with significant unvested equity. Partners entering medical residency or law school who will have very different earnings five years out. If your financial position is likely to change dramatically during the marriage, a prenup lets you lock in a framework while the stakes are still abstract, rather than negotiating during a later conflict when they aren't.
If none of these apply
Many couples don't fit any of the five and decide not to sign one. That's a reasonable choice. For a couple with simple finances, no dependents, no business interests, and comparable starting positions, the default rules in most states work out fine.
What's almost always worth doing, even without a prenup, is having the conversation. Sit down, share actual numbers, talk about debts and expected changes over the next ten years, and write down what you each understand to be true. A prenup formalizes that; without one, the exercise is still valuable.
If one or more applies
You don't need to decide today. Clause's builder is free through the draft stage, which means you can complete most of the agreement, see what it looks like, and discuss it with your partner before paying anything. That's often the lowest-friction way to find out whether a prenup is right for you.
