Prenups and the Price of Divorce: Protecting Money in Marriage

The Short Version

Divorce lawyer James Sexton and investor Kevin O'Leary both want couples to have the money conversation early, while they still like each other, because the same conversation gets more expensive every year it is put off [1][2][3]. Sexton's tool is a prenup: a properly drafted agreement that he says is binding, often costs a few thousand dollars, and works like life insurance for a marriage that will end, one way or another, in death or divorce [1]. O'Leary does not discuss prenups in this conversation; his version is due diligence by the fourth date, with blunt questions about debt, bankruptcy and goals [3]. On the price of divorce, Sexton has seen everything from about $3,500 to millions in legal fees, and he says the gap is made mostly by conflict, not by wealth [1]. His rule for anyone already in a divorce is to stop paying for a win the court cannot deliver: "I would rather you pay her than pay me." [2]

What They Said

James Sexton: a prenup is life insurance, not pessimism

Sexton is a New York divorce trial lawyer with more than two decades of high-conflict cases, and he strongly recommends prenups [1]. His argument starts from a fact that sounds harsh and is simply arithmetic: every marriage ends in death or divorce [1]. Seen that way, a prenup is like life insurance. Buying a policy does not mean you expect to die this year, and signing an agreement does not mean you expect to divorce; in his word it is realistic, not pessimistic [1].

He gives the practical details. A prenup is binding if it is drafted properly, and it often costs a few thousand dollars [1]. He warns against downloading a template, because home-made agreements fail on technicalities such as the notary acknowledgment [1]. The saving on drafting can cost the whole agreement.

His favorite structure is the simplest one: yours, mine and ours [1]. Each person has property that stays theirs, and there is a shared pot that belongs to both. He likes it for a reason that has nothing to do with divorce: it forces helpful money conversations during the marriage, since the couple has to keep deciding what goes into which pot [1].

He is just as specific about what to leave out. Courts will enforce surprising terms; he mentions one that upheld a clause cutting alimony by $10,000 a month for every 10 pounds a wife gained [1]. But he discourages two popular ideas. Fidelity clauses invite fights over proving that cheating happened, which turns a private injury into a trial of evidence [1]. Sunset clauses, under which the prenup expires after a set number of years, force an uncomfortable reassessment of the marriage right before they run out [1]. For proof that the tool works, he points to Kevin Costner, whose second divorce was governed by a well-crafted prenup after a costly first divorce [1].

Sexton on what a divorce really costs

Sexton's range is wide. The cheapest divorce he has seen was a couple who worked out their terms on a yellow legal pad and paid around $3,500 to make it binding [1]. The most expensive involved millions in legal fees [1]. What separates them is not the size of the estate. The expensive ones were driven by complex custody fights, international child abduction, drug testing, or assets hidden in trusts and LLCs [1]. Wealth does not buy an easy resolution, he says, citing the years of litigation between Angelina Jolie and Brad Pitt [1]. The reverse is also true: he says he settled an $8 billion marital estate in about a month, with four phone calls, against attorney John Titler [2].

That last example carries his theory of lawyers. He advises hiring a skilled litigator who desperately does not want to litigate [2]. Two capable trial lawyers can predict what a court would do and settle quickly, while lawyers who fear court often get outmaneuvered [2]. Mediation is great when it works, he adds, but your spouse gets a vote on whether it will [2].

The costs outside the legal bill are in his accounts too. He calls his job "full-contact storytelling" and warns that everything a person texts or posts can be used in court, so substantive arguments should not happen by text at all [1]. Of the Johnny Depp and Amber Heard trial he says no amount of money would be worth airing that in public [1]. O'Leary, from the investor's side, adds that "divorce is incredibly stressful" and that he sees the strain in the CEOs and investors he works with when their relationships are falling apart [3].

Sexton on why fighting to win costs more than it returns

In his second conversation, with Mel Robbins, Sexton names the biggest mistake people make in the middle of a divorce: seeking vindication or closure from a legal system that only produces outcomes [2]. His picture of what the court actually does is deliberately flat: "A judge divides property, sets the schedule, and then goes to lunch." [2] No one rules on who was the better spouse. He tells clients that divorce is the architecture of their post-divorce life, not the final argument of their marriage [2].

The money version of that mistake is easy to see once he states it. Some people spend $10,000 in legal fees fighting over an $11,000 account [2]. So he tells every client, "I would rather you pay her than pay me." [2] He also separates advice from noise. Someone who asks what outcome you want is giving counsel; someone who says "Take him for everything he's got" is giving entertainment [2]. One of his lines from the same conversation makes the point about method: "There is nothing you can do with a scalpel that you should do with a chainsaw." [2]

His protection against this is a written list. He urges clients to write down concrete goals and give them to someone who can read them back later, when the fight has taken over [2]. The goals should cover housing, schooling, the parenting schedule and money, and they should separate three things that feel the same in anger: what you need, what you want, and what you are entitled to [2].

He also widens the meaning of cost. "A divorce ends a marriage. It doesn't end a family." [2] He tells clients with toddlers that the decisions they make now will shape a wedding 20 years away, and asks them to picture whether the parents will be on opposite sides of the room [1][2]. Most custody cases, he notes, are simply negotiated by two people who love their children more than they dislike their soon-to-be ex. [1] His summary of the whole process is that the pain is not optional but "the damage is optional." [2]

Sexton on the cheapest conversation

Long before lawyers, Sexton says, there is a conversation a couple is avoiding, and it is "the cheapest today it will ever be." [2] The price of silence can be millions in legal fees; the price of talking now is ten uncomfortable minutes [2]. A spouse who refuses even that, he adds, is giving you important information [2]. Later, when someone is weighing divorce, he lists the people to consult (a therapist, one discreet friend, a lawyer) and then a fourth: the spouse. That conversation is the scariest, he says, but "it's actually sometimes the cheapest way to do things" [2].

Two more of his habits belong to money. Every spouse, happily married or not, should have a basic picture of the family's accounts, retirement savings and life insurance [2]. And a consultation with a lawyer is not a declaration of war: meeting a lawyer does not mean hiring one, and attorney-client privilege protects the visit [2]. He observes that marriage is the most legally significant thing most people do besides dying, yet it comes with no pamphlet [2].

Kevin O'Leary: ask the money questions by the fourth date

O'Leary reaches the same place from the other end, before there is a marriage at all. He says nothing about prenups or written agreements in this conversation; his subject is what a couple should say out loud, and when [3].

His claim is blunt: "The reason marriages fail is not because of infidelity." [3] He says any marriage can survive that, and that the union breaks up 50 percent of the time within five years because of financial stress [3]. "One outspends the other," he says, or the two are not in sync and do not share each other's goals [3]. He bases this on his businesses in the wedding industry and on the people he works with, and the summary of the conversation notes that these are his own strongly held opinions, stated as fact and not challenged much by the host [3]. His figures should be read as his view, not as a study.

From the claim comes a schedule. By the third date, if both people have stopped seeing others, start talking about the future [3]. By the fourth, ask the hard questions: Do you want a family? Where do you see yourself in ten years, working or at home with children? Has anyone in your family been bankrupt? Have you? How much credit card debt do you have, and do you pay it off every month? [3] He admits "They're tough questions." [3] He also says the people he interviewed for his books told him they were dying to ask and answer them [3]. If you like the answers, feel encouraged to keep going; if you do not, he says, do some soul searching, because "high probability, at least 50%, it's not going to work out" [3].

His reason for treating romance this way is that once the euphoria fades, a couple is in business together [3]. He tells of an engineering student whose software business already brought in about five million dollars a year, and whose fiancée had just told him she could not live with his hours. O'Leary's serious point was that the man was engaged to someone who could not take the entrepreneurial journey with him, and that the most likely outcome was divorce after they married [3]. Picking a partner, he says, is one of the biggest decisions between success and failure [3].

When Lewis Howes asks about a couple who are deeply in love but far apart on money, O'Leary does not soften it: "If they don't have the mindset now, they're never going to have it." [3] Move on, he says, because it will end in misery, and to those who call him heartless he replies, "It's always about the money." [3]

Honesty is the other half of his protection. A couple can recover from infidelity, he argues, but being caught in a lie destroys "the equity of trust" for good, and he says he learned that from a lie that severed an important relationship of his own for two years [3].

Where They Agree, and Where They Don't

They agree that early is cheap and late is expensive. Sexton prices the avoided conversation at ten minutes now against legal fees later, and wants terms agreed going in [1][2]. O'Leary wants the questions asked on the fourth date [3]. Both treat reluctance as information: Sexton about the spouse who will not spare ten minutes, O'Leary about answers you do not like [2][3].

They agree that marriage is a financial arrangement as well as a romantic one. Sexton calls it the most legally significant thing most people do besides dying [2]. O'Leary says a couple is in business together once the euphoria fades [3]. Neither thinks saying so is unromantic. Sexton is, by the account of his first conversation, an unapologetic romantic who believes love is worth its pain [1].

They disagree on why marriages end. Asked for the most common reason, Sexton rejects simple answers like cheating or money. His answer is disconnection: "Disconnection happens very slowly and then all at once." [1] The small unspoken things come first, and he calls them "a kernel of a deeper truth," with the affair or the money fight arriving late as the visible event [1]. O'Leary says it is financial stress, full stop [3]. The difference follows from where each man stands. Sexton takes marriages apart for a living and has to hear both sides of every story, so he sees the long drift behind the blowup [1]. O'Leary sees entrepreneurs and investors whose partners do or do not share their goals and spending, and he generalizes from that [3]. The two views can be fitted together, since money handled in silence is one way a couple disconnects, but neither man says so, and they should not be reported as agreeing.

They disagree on infidelity. O'Leary says any marriage can survive it if the person confesses at once [3]. Sexton does not believe in formulas. He lists a years-long secret affair among the situations where divorce is necessary, describes several kinds of infidelity, and has also seen affairs become happy 20-year marriages [1][2].

They differ on what to do with a mismatch. O'Leary's answer to a couple who are apart on money is to end it before the wedding [3]. Sexton's tools are for staying: a yours, mine and ours structure that keeps the conversation going, and talking about the little thing when you first notice it [1]. Sexton would end a marriage over money in one case, where a spouse has authored the other's life without consent, for example by liquidating a 401(k) for gambling [2].

Only one of them talks about paper. The prenup, the drafting warnings and the clauses are all Sexton's [1]. O'Leary's contribution is the conversation that would have to come before any document [3].

Why It Works

The sources give reasons, not research.

A prenup forces the conversation. Sexton's case for yours, mine and ours is that it makes a couple discuss money while married [1]. The document's value is partly the talk needed to write it, at a time when both people still want the other to be treated fairly.

Decisions made in goodwill beat decisions made in a fight. Sexton describes divorce as a process that makes otherwise logical people sometimes unrecognizable [2]. A person in that state is the one who spends $10,000 to win $11,000 [2]. Terms settled beforehand, and goals written down early and read back later, are both ways of letting the calm version of a person bind the angry one [1][2].

Courts produce outcomes, not vindication. Because a judge only divides property and sets a schedule, money spent trying to be declared right buys nothing [2]. That is why the fight to win usually costs more than it returns: the prize being fought for is not on offer.

Predictability is what settles cases. Sexton's $8 billion example worked because two capable trial lawyers could each foresee what a court would do [2]. A valid prenup supplies that predictability in advance, which is his point about Costner's second divorce [1].

Financial mismatch does not fix itself. O'Leary's belief is that money habits and goals are settled by the time people meet, so a gap found on the fourth date is the same gap that causes stress in year five [3]. He adds an observation from the founders he advises: after a sale, "it's usually their husband or wife that was the person that was taking care of the family and mitigating the risk" [3]. In his experience the partner is part of the financial result, for good or ill.

Where It Applies, and Where It Doesn't

Law varies, and this is one lawyer's practice. Sexton practices in New York, and his statements about what is binding and what courts have upheld come from his own experience [1]. The sources do not cover how rules differ elsewhere. Anyone considering a prenup or a divorce should take advice from a lawyer where they live; Sexton himself says a consultation commits you to nothing [2].

A cheap divorce needs two willing people. The yellow legal pad worked because both spouses agreed [1]. Mediation, he says, depends on your spouse's vote [2]. Where there is abuse, hidden assets, child abduction or addiction, the cost rises for reasons a cooperative attitude cannot remove, and safety comes first: he lists abuse, including financial abuse, as the first situation in which divorce is necessary [1][2].

Not fighting is not the same as giving in. Sexton's advice is to hire someone who can fight and prefers not to, and to know what you need and are entitled to [2]. Paying the other side instead of the lawyers makes sense for an $11,000 account; it is not a rule for surrendering a home or a parenting schedule [2].

O'Leary's numbers are opinion. His statement that half of marriages break up within five years over financial stress, and that any marriage can survive infidelity, are personal convictions and the episode presents them that way [3]. His fourth-date timetable comes from a man who also asked a student which was easier to replace, his business or his fiancée, and conceded it was probably not the right thing to say [3].

Paper does not replace attention. In Sexton's account the marriages that end are the unattended ones [1][2]. A prenup limits the damage of an ending; it does nothing about the drift that leads to one.

What To Do With It

1. Ask the hard questions early. Before a relationship is serious, cover O'Leary's list: children, where each of you sees yourself in ten years, bankruptcy in the family or your own past, credit card debt and whether it is paid off monthly [3].

2. Get a prenup, drafted by a lawyer. Treat it as insurance. Expect a few thousand dollars, and do not use a downloaded template that can fail on a technicality such as the notary acknowledgment [1].

3. Use yours, mine and ours. Keep the structure simple, and let it prompt regular conversations about what belongs in the shared pot [1].

4. Leave out fidelity and sunset clauses. The first invites a fight over proof; the second schedules a reassessment of the marriage [1].

5. Know the family's finances whether or not you are happy. Have a basic picture of the accounts, retirement savings and life insurance. If divorce is coming, copy key financial documents, know your logins and secure access to money for a lawyer [2].

6. Have the ten-minute conversation now. Sexton's test and opener are simple: ask your spouse whether they are happy, and say you want to do a good job of being married to them. It costs less today than it ever will again [2].

7. Consult a lawyer before you need one. A meeting is privileged and does not commit you to anything. If you hire, choose a skilled litigator who would much prefer to settle [2].

8. Write your goals down and hand them to someone. Cover housing, schooling, the parenting schedule and money, sorted into what you need, what you want and what you are entitled to, and have that person read them back when the fight heats up [2].

9. Do the arithmetic before every fight. Compare the legal fees with the thing being fought over. If it is $10,000 for an $11,000 account, pay the other side and not the lawyers [2].

10. Keep arguments out of texts and posts. Anything written can be read in court, and no sum is worth a public airing [1].
