⚠️ This article gives general information about United States law. It is not legal advice. Family law is state law, and it differs substantially from one state to another. Consult your own attorney.
This is the moment when everything you have built is decided, and it is the moment women are least prepared for. It is also when his assets are finally put on paper, the last of the checks described in how to spot a fake rich man.
Three realities to take in before going further:
- He will have a lawyer. That lawyer works for him, that is the job, and they will do it well.
- The document you sign will govern twenty years of your life. And it will be very hard to change afterwards.
- The time to negotiate is before the wedding. Afterwards, you do not negotiate: you defend, from a much weaker position.
The absolute rule: never sign a prenuptial agreement without your own attorney. Not his lawyer, not a “neutral” drafter — your attorney, whom you pay, who represents only your interests. Budget a few thousand dollars. It is the highest-return expenditure of your life. It also protects him: independent counsel on both sides is one of the most commonly cited factors when courts uphold these agreements.
What happens with no agreement: two systems
In the absence of a prenuptial agreement, your state’s default rules apply, and they fall into two families.
Community property states
Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington and Wisconsin.
| Stays separate | Becomes community |
|---|---|
| What each spouse owned before the marriage | Essentially everything earned or acquired during the marriage |
| Gifts and inheritances received by one spouse | Both spouses’ income |
| Often, the increase in value of a separate business attributable to a spouse’s work |
Equitable distribution states
All the others. The court divides marital property “equitably”, which does not mean equally: it weighs the length of the marriage, each spouse’s contribution — including non-financial contribution — earning capacity, and the standard of living.
What this means for you. In both systems, the wealth he had before the marriage stays his. You share what is created during the marriage. That can be considerable if his company grows, or very small if he lives off existing assets.
Verdict: the default rules are often more favorable to you than what will be proposed — which is precisely why something else will be proposed.
The two systems, and what separate property covers, are compared in detail in community property vs equitable distribution.
What will be offered: full separation
A prenuptial agreement that keeps everything separate, waives or caps spousal support, and treats income during the marriage as separate property.
What this means for you. If you have no income of your own, you accumulate nothing. You can be married fifteen years to a man whose net worth tripled and leave with nothing.
It is also the structure that best protects a founder against business risk — which is a legitimate argument, not a pretext.
Verdict: acceptable, but never on its own.

The seven trade-offs to negotiate
If full separation is imposed — and it will be — here is what must come in exchange. These are not favors: they are the standard balances in this kind of agreement.
| Element | Importance |
|---|---|
| A carve-out for the marital home — the home is treated as joint property regardless of who pays | ⭐⭐⭐ The most useful clause |
| Joint title on the home — you own a share even if he funds it | ⭐⭐⭐ The most concrete and easiest to obtain |
| A sunset or escalator clause — your share increases with each year of marriage | ⭐⭐⭐ The fairest structure over twenty years |
| Life insurance naming you as beneficiary, with a stated minimum | ⭐⭐⭐ It passes outside probate. ⚠️ A beneficiary designation can be changed unilaterally and without telling you — check it every three years |
| Written compensation for reducing or stopping work | ⭐⭐⭐ Non-negotiable if you scale back your career |
| Funded retirement contributions during any interruption — a spousal IRA at minimum | ⭐⭐ Almost always forgotten, and very expensive over twenty years |
| A guaranteed right to remain in the home for a defined period | ⭐⭐⭐ Critical if he has children from a first marriage |
Five terms to understand before you negotiate
These words come back in every negotiation. Knowing them before the first meeting with your attorney saves time and money.
- Full financial disclosure. Each side lists assets, debts and income before signing. Under the Uniform Premarital Agreement Act, adopted in some form by many states, an agreement that was unconscionable when signed, without fair and reasonable disclosure, can be set aside. Ask for the schedules, and read them.
- Independent counsel. Each spouse has an attorney of their own. Some states go further: California will not enforce a waiver of spousal support unless the spouse giving it up had independent counsel, and requires seven days between receiving the final agreement and signing it.
- Alimony (spousal support). Many agreements waive or cap it. Some states allow a court to refuse a waiver that would be unconscionable when enforced, but that is a fight, not a guarantee.
- Sunset clause. Strictly, the agreement, or part of it, lapses after a set number of years of marriage. The word is also used loosely for the escalator described above.
- Equalization clause. A defined payment or share that rebalances the gap at dissolution, often calculated on the growth of each spouse’s net worth.
In the UK. In England and Wales, a prenuptial agreement is not automatically binding. Since the Supreme Court’s decision in Radmacher v Granatino (2010), courts give effect to an agreement freely entered into, with a full understanding of its implications, unless it would be unfair to hold the couple to it. In practice: independent legal advice on each side, full disclosure, signing well before the wedding, and provision for the children’s needs. Scotland has its own rules.
⭐ The question to ask, word for word
“If we divorce in fifteen years and I have reduced my professional activity, what exactly will my financial position be?”
Get the answer in writing. The answer to that one question tells you whether the agreement on the table is balanced.
Children from a first marriage
Extremely common in the 45–58 bracket, and the most delicate situation.
The human side of it, before any clause, is covered in dating a man with adult children.
What you need to know:
- Most states give a surviving spouse an elective share — a minimum portion of the estate that cannot be disinherited. But a prenuptial agreement can waive it, and many do. Read that clause specifically.
- Assets held in trust before the marriage generally stay outside the estate entirely.
- Adult children from a first marriage often oppose any provision in your favor. That is human.
What to put in place, together:
- A will or revocable trust that states your position explicitly
- Life insurance with a clear beneficiary designation — it passes outside the estate
- A guaranteed right of occupancy in the home, expressly written
Negotiate all three at the same time, with an estate attorney, and if possible discuss it openly with the adult children. A provision that is accepted is worth more than one that is contested.
Living together without marrying
| Protection | |
|---|---|
| Marriage | A complete framework, whatever the agreement says |
| Common-law marriage | Recognized in only a handful of states, with strict conditions. Do not rely on it |
| Cohabitation | ⚠️ No protection of any kind in most states. Twenty years together, his children raised, and no rights — not to the home, not to the assets, not on death |
⚠️ If you live with a wealthy man without being married and you have reduced your professional activity, you are in the most exposed position that exists. It is the configuration that produces the worst outcomes. A written cohabitation agreement is the minimum.
How to raise it
The right moment: as soon as marriage becomes a serious hypothesis. Never three weeks before the ceremony — an agreement signed under time pressure is a badly negotiated one, and in several states it is also more vulnerable to challenge.
The wording:
“I want us to set this up properly, for you as much as for me. You have assets to protect, that’s normal and I understand it. I want to be sure I won’t be in difficulty if things go wrong, or if something happens to you. Let’s see an attorney, and I’ll have my own so I understand everything.”
What that wording does: it acknowledges his need for protection, which defuses defensiveness; it frames yours as symmetrical and legitimate; and it announces your attorney as obvious rather than as distrust.
His reaction is major information:
- ✅ He finds it normal, proposes his attorney and accepts yours → a serious man.
- ⚠️ He is uncomfortable but agrees → normal, the subject is hard. Keep going.
- ❌ He refuses, takes offense, says “if you loved me you wouldn’t ask”, or insists you use his lawyer alone → major signal. See the ten signs of a dangerous profile.
The most important point
A clear prenuptial agreement is not a bet on failure. It is what lets you stop thinking about it.
And it protects the couple too: a clear, balanced agreement removes a source of suspicion that otherwise never quite goes away. Once the frame is set, money stops being a latent issue in every decision. You can get on with living.
