What Should a Woman Ask for in a Prenup? A Checklist for the Lower-Earning Spouse

For most of their history, prenuptial agreements were written to protect the richer spouse from the poorer one. That is no longer who is asking for them.

Not legal advice. This article is general information only. Prenup laws differ by state and change over time. Consult a licensed attorney in your state before acting on anything here.

Women now start a little over half of all prenup conversations, according to platform data reported by Slate in 2025.

That shift matters most for the spouse who plans to earn less, work part time, or leave a job entirely to raise children.

If that is you, a prenup is not automatically the thing that takes your money. Signed badly, it is.

Signed well, it is the only document that puts a number on what your unpaid years are worth.

This guide covers what to ask for, what a prenup can and cannot do to alimony, and the clauses that protect the person who steps back.

Key Takeaways

• A prenup can waive or limit alimony in 48 of the 51 US jurisdictions. Only Iowa, New Mexico, and South Dakota refuse to enforce a spousal support waiver outright.
• The spouse who leaves the workforce carries the loss. The Center for American Progress puts the lifetime cost at about $415,000 for a 30-year-old earning $50,000 who takes three years out.
• A mutual waiver of alimony is not a neutral deal. It reads as even and lands almost entirely on whoever earns less.
• Ask for a support floor, a leaving-the-workforce trigger, continued retirement contributions, and a re-entry fund, not a blanket waiver.
• Child support cannot be signed away in a prenup anywhere in the country. The right belongs to the child, not the parents.
• In California, a spousal support waiver is unenforceable unless the party giving it up had independent legal counsel when signing.

Why the Lower Earner Has the Most to Lose

Stay-at-home parenting is still mostly done by women. Pew Research Center found that fathers make up 18% of stay-at-home parents, which leaves 82% of them mothers.

The same 2021 Current Population Survey data shows 26% of mothers were stay-at-home, against 7% of fathers.

The financial hit from those years is larger than the missed paychecks. The Center for American Progress modelled a 30-year-old woman earning $50,000 who takes three years off for child care.

She loses $150,000 in wages she did not earn. She also loses about $140,000 in wage growth that never compounds, and roughly $125,000 in retirement assets and benefits, for a lifetime cost near $415,000.

Peer-reviewed work finds the same pattern. Kleven, Landais, and Søgaard, writing in the American Economic Journal: Applied Economics in 2019, found that the arrival of children creates a long-run gender earnings gap of around 20%, driven by hours, participation, and wage rates.

That study uses Danish data, and US penalties tend to run larger.

None of this shows up on a balance sheet at divorce.

The house and the 401(k) are visible. The career that was traded for them is not.

What Should a Woman Ask for in a Prenup?

The list below is written for the spouse who expects to earn less or pause a career. Every item is a clause you request, not a right you already have.

A Support Floor Instead of a Waiver

The single most common mistake is agreeing to a mutual alimony waiver because it sounds fair.

It is symmetrical on paper and lopsided in practice. If one of you will out-earn the other by a wide margin, a mutual waiver only ever collects from one side.

Ask instead for a defined floor. Attorneys quoted by the Wall Street Journal describe formulas such as a set number of months of support for each year of marriage, or a flat sum per year married.

A Leaving-the-Workforce Trigger

This is the clause built for exactly this situation, and reporting suggests demand for it is growing.

It sits dormant and activates only if one spouse reduces hours or stops working. Support terms then step up according to how long they were out.

Define the trigger carefully. Say whether it covers a full exit, reduced hours, or a move to part time, and whether eldercare counts alongside child care.

Be honest about the number here. You will see a claim online that about one in four prenups now contain a workforce trigger.

That figure has no survey or dataset behind it, so treat the trend as real and the statistic as invented.

Retirement Contributions That Keep Running

Years at home are years of no 401(k) match and no Social Security credits.

Ask for an annual contribution to a spousal IRA or a transfer into an account in your name for every year you are out of paid work. This is the loss people forget, and it was $125,000 of CAP’s $415,000.

A Career Re-Entry Fund

Getting back to work after five years out costs money before it earns any.

Ask for a defined sum for retraining, certification, or tuition, payable if the marriage ends. Some agreements phrase this as a re-entry payment tied to continuing education.

Housing Stability

If you are the parent with the children most of the time, moving out immediately is the disruption that hurts them first.

Ask for a right to stay in the home for a defined period, or for the down payment to be traced back to you.

Step-Ups Tied to Years and Children

A prenup written at 28 should not still govern you at 45 on identical terms.

Ask for terms that grow with the marriage. A common structure raises your share or your support entitlement at set anniversaries, or on the birth of a child.

The opposite of this, a sunset clause that voids the whole agreement after a set number of years, cuts the other way. It suits whoever the agreement currently disadvantages.

If you are already married, these same terms are still available to you, but they go in a postnup rather than a prenup, and the enforcement bar is higher.

Life Insurance Backing the Promise

A support obligation is only as good as the person paying it.

Ask for a term policy naming you, sized to cover the support the agreement promises, with proof that premiums are being paid.

Independent Counsel, Paid For

Ask that the wealthier spouse covers your lawyer.

This is not only fairness. In California it decides whether a support waiver binds you at all, and everywhere else it is the fact that most often defeats a later claim that you were pressured.

Can a Prenup Prevent Alimony?

In most of the country, yes.

The Uniform Premarital Agreement Act, at Section 3(a)(4), lets parties contract with respect to “the modification or elimination of spousal support.”

The Iowa Supreme Court surveyed the whole country in In re Marriage of Erpelding in 2018 and counted it precisely: “Forty-eight jurisdictions allow premarital waiver of spousal support.”

The Three States That Say No

The same opinion names the holdouts: “Three jurisdictions categorically do not allow waiver of spousal support. They are Iowa, New Mexico, and South Dakota.”

Iowa’s statute is blunt. Section 596.5(2) says the right of a spouse or child to support “shall not be adversely affected by a premarital agreement.”

South Dakota gets there by omission, listing what a prenup may cover and leaving support off the list.

The Second Look

Signing a waiver does not always end the argument. Some states test the agreement again at divorce, not only at signing.

Connecticut is the clearest. Its statute makes an agreement unenforceable if it “was unconscionable when it was executed or when enforcement is sought.”

Massachusetts asks whether the agreement is still fair and reasonable at judgment, but sets a high bar. Under DeMatteo v. DeMatteo, a judge steps in only where enforcement would leave the contesting spouse “without sufficient property, maintenance, or appropriate employment to support” herself.

Read that limit closely before relying on it. The same court said an agreement is not unenforceable merely “because it is one sided.”

A bad deal is not an unenforceable one. Courts rescue people from destitution, not from regret.

California Has Its Own Rule

California Family Code Section 1612(c) does two things at once.

A spousal support waiver is unenforceable if the party giving it up was not represented by independent legal counsel when the agreement was signed. It is also unenforceable if it is unconscionable at the time enforcement is sought, whether or not there was a lawyer.

Note the split. In California that second look applies to support only, while the rest of the agreement is judged as of signing.

What a Prenup Cannot Take Away

Two things sit outside the deal no matter what either of you signs.

Child support is the first. UPAA Section 3(b) states that the right of a child to support “may not be adversely affected by a premarital agreement.”

The Indiana Supreme Court explained why in Straub v. B.M.T.: “Neither parent has the right to contract away these support benefits. The right to the support lies exclusively with the child.”

Custody is the second. A prenup’s custody terms do not bind a court, which decides parenting questions by the best interests of the child at the time of the dispute.

The reasoning is that parents cannot waive the rights of people who were not party to the contract, including children not yet born.

One caveat worth knowing. A few states, New Jersey among them, let parents submit custody questions to binding arbitration, subject to judicial review.

That is a narrow exception to a general rule.

Is Asking for a Prenup a Red Flag?

It depends entirely on how it arrives.

A prenup produced a week before the wedding, drafted by one side’s lawyer, with a request to just sign it, is a red flag about the person rather than the document.

A prenup raised early, with both sides’ finances on the table and both sides represented, is the opposite.

Timing carries legal weight too. California requires at least seven calendar days between receiving the final agreement and signing it, and courts elsewhere have split on whether a few days’ notice makes a signature involuntary.

How to Bring Up a Prenup

Raise it away from wedding logistics, months out, when nothing is scheduled.

Lead with the arrangement you both expect rather than the paperwork. Who is taking time off, whose job moves if a job moves, what happens to the second income when a child arrives.

Those questions get asked in a prenup whether or not you have one. The only choice is whether you answer them now or a judge answers them later.

If you are the one being asked to sign, the request that ends the argument is simple. Ask for your own lawyer, paid for, and for enough time to use one.

What Should a Man Ask for in a Prenup?

Everything above applies to whoever steps back, and that is increasingly men.

Pew’s numbers put fathers at 18% of stay-at-home parents, up from 11% in 1989.

A father who cuts to part time so his wife can take a promotion carries the same lost wage growth and the same missing retirement contributions.

Spousal support statutes are gender-neutral. The clause protecting the stepping-back spouse should be written that way too, since neither of you can be sure today which of you it will be in twelve years.

Where the higher earner’s list differs is in what it protects: a business or professional practice, an expected inheritance, equity in a company, and separation of premarital debt.

What This Costs and Where to Get One

Prenup pricing splits into two paths.

Attorney-drafted agreements generally run from about $1,500 to $5,000 or more per person, and rise with complexity.

Online platforms are the cheaper route. HelloPrenup charges a flat $599 per couple and covers 47 states plus DC, and our review walks through where it fits and where it does not.

Here is the honest caveat for this particular article. A platform is a good fit when both people are cooperative and the finances are straightforward.

The spousal support clause is the one place where that logic strains, because it is the clause most likely to be attacked later and the only one California voids outright without independent counsel.

A workable middle path is drafting online and paying a lawyer to review the support terms alone. That keeps most of the cost saving while putting a professional on the clause that decides whether your unpaid years are worth anything.

If you are still mapping out the basics, our prenup hub covers requirements in all 50 states.

Final Thoughts

The old assumption was that a prenup is something a wealthy spouse does to a poorer one. The people signing them now are mostly not wealthy, and a little over half of the time it is the woman asking.

The document is neutral. It records whatever bargain you put in it.

What makes it dangerous to the lower earner is not the prenup itself but the mutual waiver that sounds even, signed without a lawyer, without disclosure, and too close to the wedding.

What makes it useful is the opposite. Name the career pause, put a number on it, fund the retirement account, and pay for the other side’s attorney.

Do that and the agreement stops being a way to leave with less. It becomes the only place your unpaid work is written down as work.
