A couple who look like most couples

Two people are getting married in six months. One bought a condo five years before they met and still has a mortgage on it. The other has student loans. Neither has anything like a fortune. The one who owns the condo earns more now, and they both expect that when they have children the other will stop working for a few years.

Nothing in that description sounds like a prenup, which is exactly the problem. Read as a list of legal facts rather than as a life, it contains five separate questions that state law is going to answer for them, silently, on the day they marry.

The same couple, read as their state will read them
What is true about themWhat their state decides about it
One of them owned the condo before the marriageWhether it stays entirely theirs once married earnings are paying the mortgage and improving it, and what proof it takes to show it was separate years later.
The other has student loansWhether marriage exposes any of the first person's property to that lender, and whether married money used to pay the loans down is ever accounted for.
One earns substantially moreHow income earned during the marriage is characterized, which in some states makes it shared the moment it is earned.
One expects to stop working for a few yearsWhether the law recognizes that contribution, and what happens to the retirement savings that do not accumulate during those years.
Neither has updated a will since they metWhat the survivor is entitled to claim if one of them dies, which in most states is not nothing and is not decided by the will alone.

They may well read all five answers and find them reasonable. That is a good outcome and it is available to them only if they look. The version of this that goes wrong is not the couple who decline an agreement. It is the couple who never found out what they were declining.

The facts that make this live

Work through these as facts about your household rather than as a quiz. Each one is here because it changes what the default rules do to you, and none of them is about being rich.

Property and money

  • Does either of you own a home, or any real estate?
  • Will one of you be moving into a property the other owns and contributing to the mortgage?
  • Does either of you own a business, or part of one, or intend to start one?
  • Does either of you hold equity, options, royalties or intellectual property?
  • Are there retirement accounts on either side with meaningful balances?
  • Does either of you own property in a different state, or outside the country?

Debt and obligations

  • Is either of you bringing significant debt: student loans, tax debt, consumer debt, a business loan?
  • Has either of you co-signed anything for somebody else?
  • Does either of you support a parent or another relative financially?

Family and inheritance

  • Does either of you have children from an earlier relationship?
  • Is this a second or later marriage for either of you?
  • Does either of you expect an inheritance, or benefit from a family trust?
  • Is there family property or a family business either of you is expected to keep in the family?
  • Does either of you already have a will or trust written for a different family shape?

Work and contribution

  • Does either of you expect to stop working, cut hours, or relocate for the other's career?
  • Will one of you support the other through school or training?
  • Will one of you work in or help build a business the other owns?
  • Is there a large and durable difference in what the two of you earn?

One yes is enough to make the question worth an hour. It is not enough to make the answer yes. What a yes tells you is that there is a specific default rule with your name on it, and that finding out what it says is cheap.

When the answer is reasonably no

Sahvelo has no interest in telling every engaged person they need an agreement, and a page that could only reach one conclusion would not be worth reading. There are real situations where the honest answer is that this is not worth doing.

  • Neither of you owns much, neither of you owes much, neither of you expects to inherit, there are no children from anywhere else, and neither of you has a business. The defaults were written for roughly this situation.
  • You have read what your state does and it is close enough to what you would have written. An agreement that restates the default rules costs money and achieves nothing.
  • The only thing driving it is a family member who wants it, and neither of you can name a decision it would change. That is somebody else's agreement.
  • It is late, one of you is under pressure, and the honest choice is between a rushed document and none. A rushed agreement is not a safer version of no agreement.

There is also the version worth naming plainly: some couples find the conversation itself useful and the contract unnecessary. Working out what you each think about debt, saving, housing, children, caring for parents, whose career gives way and what should happen to each of you if the other dies is valuable whether or not anybody signs anything at the end of it.

What this is not for deciding

Two limits are worth knowing before the conversation starts, because assuming otherwise wastes the conversation.

Custody, parenting time and child support are not yours to settle in advance. Those are decided on a child's interests when the question actually arises, and a child is not a party to their parents' contract. States commonly provide that a child's right to support cannot be adversely affected by a premarital agreement.

An agreement does not move an asset. A house passes by its deed, an account by its beneficiary form, an employer retirement plan by the plan's own paperwork and the spousal consent given on it after the marriage. Whatever you agree, the documents that actually control those assets have to be changed separately.

And one that is about pressure rather than about law. If one of you is being told to sign before the wedding or the wedding is off, that is not a timing problem to be solved by hurrying. It goes to whether the agreement was entered into voluntarily, which is something states care about, and it is a reason to get independent advice immediately rather than to sign now and deal with it later.

How Sahvelo would approach it

This page is Sahvelo's judgment about how to make a decision, not a statement of any state's law. No agency publishes when a couple needs an agreement, and none could. Sahvelo earns nothing from either answer here, and it is also not your lawyer. Every legal question this page raises is answered by your own state and by counsel there.

Find out what the default is before deciding whether you want it

This is the step almost nobody takes and it is the cheap one. Read what your state decides about property acquired during a marriage, what a surviving spouse can claim from an estate, and what it takes to prove something was separate. You cannot evaluate an agreement without knowing what it is replacing.

Instead of deciding from a general impression that prenups are for wealthy people or that they predict divorce

Decide from the facts on the list, not from how much you have

Money is a poor predictor here. A couple with modest savings, one house owned before the marriage, one person's student debt and a plan for somebody to stop working has more moving parts than a wealthy couple who both work and own nothing jointly. Work the list of facts and count the yeses.

Instead of using a net worth figure as the threshold

Buy an hour before you buy a document

Most couples need to know what their state does and whether their situation has anything unusual in it. That is one conversation with family-law counsel in the state you will live in, with your asset and debt lists written down beforehand. It is a fraction of the cost of a negotiated agreement, and it is what tells you whether you need one.

Instead of commissioning an agreement to find out whether you need an agreement

Both of you evaluate it, or it is not finished

Coverage of this subject is written almost entirely for the person with more to protect. An agreement the other person did not really assess is both unfair and weaker, because voluntariness and understanding are exactly what gets tested later. If one of you cannot say what they are giving up and what they are getting, the work is not done.

Instead of treating the person with fewer assets as the one who signs

Start early enough that timing is not part of the negotiation

There is no national waiting period and Sahvelo will not invent one, but the reason to start early holds everywhere: a document produced in a week is a document nobody read properly, and pressure close to a wedding is the thing most likely to be argued about afterward. Months, not weeks.

Instead of raising it once the invitations have gone out

Plan for the ordinary ending as well as the bad one

Far more marriages end with somebody dying than with a contested division of assets, and the rights that attach at that point are the ones most couples have never heard of. Ask what each of you would be entitled to claim if the other died tomorrow, and whether that matches what you both assume.

Instead of treating this as a divorce document and skipping the estate half

Treat the conversation as the deliverable

If you get to the end and decide against signing, you should still leave knowing what you each own and owe, what your state would do, whose career gives way, how debt is handled and what happens if one of you dies. That is worth having whether or not there is a contract at the end of it.

Instead of abandoning the subject as soon as you decide against a document

Questions people ask about this

  • How much money do you need before a prenup makes sense?

    There is no figure, and any figure would be an invention. What makes the question live is complexity rather than size: one house owned before the marriage, one person's debt, one business, one expected inheritance, one child from an earlier relationship, or one person planning to step back from work. A couple with none of those and modest savings genuinely may not need one. A couple with two of them may need one at any income.

  • Does raising it mean we think the marriage will fail?

    It is a fair worry and the framing is what causes it. An agreement is a decision about which default rules fit your life, and those rules apply from the day you marry, not from the day anything goes wrong. They also decide what happens when a marriage ends the ordinary way, which is that somebody dies. A couple who discuss debt, careers, a house and what each would be left with are not planning to separate; they are doing the thing people say couples should do before they marry.

  • If I die first, what does my spouse get?

    More than the will alone decides, and more than the word “spouse” suggests. Most states give a surviving spouse a claim against the estate that the will cannot simply remove, and some states measure that claim against assets which never enter probate at all, such as joint accounts and payable-on-death designations. An employer retirement plan is separate again: it usually treats a spouse as the default recipient of the death benefit, and naming anybody else requires that spouse's written consent, acknowledging the effect of the election and witnessed by a plan representative or a notary. If that is not the outcome the two of you want, an agreement is one of the instruments that can change it, and it is not the only document that has to change. What your own state does is on the prenups page, which reads four of them at source.1

  • My fiance says the wedding is off unless I sign this week. What do I do?

    Get your own advice before you sign anything, today if you can. Sahvelo cannot tell you whether a particular agreement would be enforced, and it is not going to tell you to sign or not to sign. What it can tell you is that whether an agreement was entered into voluntarily, and whether each person understood what they were giving up, are things states care about, and that pressure applied close to a wedding is exactly the circumstance that gets examined afterward. A lawyer of your own, chosen by you, is the right next step rather than a faster reading of the document.

  • We do not have much. Is a prenup pointless?

    Not automatically, and the reason has nothing to do with what you have now. Default rules govern what you acquire during the marriage, what happens to debt either of you brings, and what a survivor can claim. A couple who own little today but expect one person to stop working, or who are bringing one person's student loans and one person's condo, have several live questions. What is true is that a couple with no property, no debt, no children elsewhere and no business are close to the situation the defaults were written for.
