How Rich Do You Have to Be for a Prenup in 2026?

There's No Net Worth Minimum for a Prenup

You don't need a specific amount of money to get a prenup. There's no legal wealth threshold, and these agreements are increasingly common across every income level. The old idea that prenups belong only to celebrities and the ultra-wealthy is out of step with how couples actually use them now.

The numbers back this up. A Harris Poll survey of over 1,000 people found that 15% of married or engaged respondents had signed a premarital agreement in 2022, up from just 3% in 2010. That's a fivefold jump in about a decade, driven largely by couples who aren't rich but who have real debts, income, and future earnings to think through together.

So the better question isn't "Am I rich enough?" It's "Do my partner and I want to decide these things ourselves, or leave them to a default statute?" A prenup is a way to create clarity before you're married, when you're both calm and working toward the same goal. That's a partnership decision, not a wealth calculation.

At Neptune, couples don't navigate this alone. We pair you with experienced attorneys, Certified Financial Planners (CFPs), and CPAs, then manage the process from the first financial inventory to the final signature so both partners plan it together.

What a Prenup Actually Does for a Couple

A prenuptial agreement is a contract two people sign before marriage that outlines how they'll handle money, property, and debt, both during the marriage and if it ends. You sign it before the wedding, but it doesn't take effect until you're legally married.

Without one, your state's divorce statutes decide everything by default. That means the law, not you, determines how property gets divided, whether spousal support (also called alimony) is on the table, and what happens to assets each of you brought in. The Uniform Premarital Agreement Act, adopted in some form by roughly 26 states, exists precisely because lawmakers recognized couples deserve a way to make these decisions themselves. State law varies significantly, so what's enforceable in one state may be analyzed differently in another.

A prenup has clear limits. It cannot address child custody or child support. Those matters are decided under state law based on the child's best interests at the time, and no agreement signed years earlier can override that. A prenup covers the financial relationship between the two adults signing it.

The healthiest way to think about a prenup is as two people making financial decisions together, in good faith, before any conflict or emotion enters the picture. It's a document about clarity, not distrust.

The Real Signals You Need a Prenup (Not Wealth Level)

Here's what actually signals a prenup makes sense, and none of it is a bank balance. The strongest indicators are separate property you want to keep separate, business ownership, an expected inheritance, children from a prior relationship, and significant debt on either side.

Separate property is the tricky one. In every state, property you owned before marriage stays separate in theory. In practice, it commingles fast. The moment inherited money lands in a joint account, or a pre-marriage home gets a shared mortgage paydown, the lines blur. Without an agreement, appreciation on separate property during the marriage may be deemed marital and subject to division. A prenup spells out what stays separate and how any growth in value is treated.

Business ownership is the single most common reason. Without a prenup, the non-owner spouse may end up entitled to a share of the business's appreciation, or even claims against business assets. A prenup can state that the business remains separate and how a partner would be compensated, if at all. Business partners sometimes require a prenup so a divorce can't pull an ex-spouse into the ownership structure.

Forward-looking situations matter too. High earners who aren't rich yet often hold restricted stock units (RSUs), stock options, or equity that hasn't vested. RSUs vesting during the marriage are generally treated as marital property in most states, and courts apply formulas that can produce results neither partner expected. A prenup can define whether that equity is separate or marital and how to handle unvested grants.

Finally, consider the partner who plans to stay home or support the other through school. A prenup can guarantee a defined level of spousal support or a lump-sum payment, giving the lower earner real certainty rather than relying on a judge's discretion later. That's why framing a prenup as a tool for only the higher earner misses half its value.

How Common Prenups Are by Financial Situation

Prenups fit different couples for different reasons. Here's how the common financial profiles line up.

Costs vary by complexity, location, and which attorney you use. Financial planners have seen prenups range anywhere from $2,000 to $15,000, while flat-fee online platforms can run around $599 for straightforward agreements. Full-service options that include financial and tax review sit higher because they do more of the work.

Data indicates couples with over $1 million in assets use prenups more than 60% of the time. But the trend line shows lower-asset couples adopting them steadily, because the debt and equity questions apply to everyone. Money conflict is one of the top predictors of divorce, which is exactly why wealth advisors increasingly suggest every couple at least consider an agreement.

How Couples Plan a Prenup With Neptune

The process starts long before anyone drafts a document. It begins with a full financial inventory: each partner lists income, account balances, debts, property, retirement accounts, investments, business interests, and expected inheritances. Documenting your present financial situation honestly is the foundation everything else rests on.

Enforceability generally comes down to three requirements. The agreement must be voluntary, with no pressure on either side. Both partners must provide full financial disclosure. And each person should have independent legal review, meaning their own attorney. Some states, like California, require independent counsel for certain terms such as an alimony waiver. Skip these steps and a court can set the agreement aside.

Timing matters too. Signing well before the wedding, generally at least 30 days out, reduces any argument that one partner was rushed or pressured. Leaving it to the week of the ceremony invites problems.

Neptune manages this full process end to end. We pair you with attorneys who each bring 20+ years of experience, plus CFPs and CPAs who handle the financial and tax picture, so both partners get independent guidance and the disclosure requirements are met. We shepherd everything from the first inventory to the signed agreement, with guided education along the way so you understand each decision rather than just approving paperwork.
