Family law attorneys will tell you the same thing before they discuss anything else: a prenuptial agreement isn't really about what you own right now. It's about what you might owe, what you might earn, and what you might inherit before the marriage ends. Most couples skip this conversation because they assume a prenup only makes sense when one partner shows up with a house and a brokerage account. That assumption is wrong, and it costs people.
Whether a prenup makes sense for you turns on a few variables that most generic advice glosses over: the debt you're each carrying into the marriage, the income trajectory your careers are on, and whether either of you expects to receive an inheritance. None of those are resolved by what sits in your bank account today.
Here's the tension worth sitting with before you decide: a prenup costs money to draft properly, and for couples with genuinely modest finances, that cost is real. But skipping one doesn't eliminate legal exposure. It just means your state's default divorce statutes decide things for you, and those defaults were written for generic situations, not yours. The question isn't whether you can afford a prenup. It's whether you can afford to let the state choose your fallback.
What a Prenup Actually Covers (and What It Doesn't)
The persistent myth is that prenups exist to protect rich people's assets from their less-wealthy spouses. That framing misses something. A prenuptial agreement is a contract that lets two people define in advance how they'll handle property, debt, and financial obligations if the marriage dissolves. The asset protection angle is only one use case, and for couples without significant assets, it's probably not the most relevant one.
What tends to matter more for lower-asset couples is the debt side. Under most states' equitable distribution laws, debt acquired during marriage can become a shared liability, even if only one spouse ran it up. Student loans taken out before the wedding are typically treated as separate property, but the picture gets murkier with ongoing graduate school debt, credit cards, or a business loan one partner signs during the marriage. A prenup can define explicitly which debts stay with which person. That's not a wealthy-couple problem. That's a debt-is-common-in-America problem.
Prenups can also address future income and career-related compensation, including equity stakes, commissions, or professional licenses acquired during the marriage. If one partner is mid-career in a field with significant earning upside, and the other is not, that asymmetry is something to decide consciously rather than leave to a divorce court. The same applies to inheritance: if a parent is likely to leave one spouse a meaningful sum, a prenup can designate that inheritance as separate property rather than marital property, which is the default treatment in some states if the funds get commingled.
What prenups cannot do: they can't override child support or custody arrangements (courts determine those based on the child's best interest at the time of divorce, not what a contract signed years earlier says), they can't include provisions that are unconscionable or that were signed under duress, and they generally can't waive a spouse's right to alimony in a way that leaves them eligible for public assistance. Those are hard limits regardless of how the agreement is written.
The Real Cost Calculation
A basic prenuptial agreement drafted by a family law attorney in the US typically runs somewhere between $1,500 and $3,000 for a straightforward situation, though contested or complex agreements go higher. That's a real number for couples living paycheck to paycheck, and pretending otherwise doesn't help.
But the cost comparison that actually matters isn't prenup vs. nothing. It's prenup vs. contested divorce. According to the American Academy of Matrimonial Lawyers, contested divorces with property disputes routinely cost each spouse $15,000 or more in legal fees. A prenup doesn't prevent a divorce, but it dramatically reduces the scope of what a court needs to decide, which is what drives legal costs down. If the marriage ends amicably, the prenup barely gets used. If it ends badly, having clear terms in writing may be the only thing keeping a difficult situation from becoming an expensive one.
Or rather: the real calculation isn't just about divorce costs. It's about what happens to your financial life during the years between marriage and any potential divorce. A couple that enters marriage with $40,000 in combined student debt and no prenup has made a default decision about how that debt would be treated if they split. They just didn't make it consciously. Over a five-to-ten-year marriage, that same couple might accumulate significantly different income levels, one partner might receive an inheritance, or one might start a business. Each of those events changes the financial stakes without changing the legal default they locked in on their wedding day.
For couples with genuinely minimal assets and no debt, no income asymmetry, and no expected inheritance on either side, a prenup may not clear its own cost threshold. That's a legitimate conclusion. But it needs to be reached by actually evaluating those four factors, not assumed because neither partner currently has much in their checking account.
When a Prenup Makes Sense on a Tight Budget
The situations where a prenup earns its cost, even for lower-income couples, follow a recognizable pattern. Check debt load, income trajectory, inheritance likelihood, and business involvement first.
Significant pre-marital debt on one side is the clearest trigger. If one partner is entering the marriage carrying $80,000 in student loans or $25,000 in credit card debt, a prenup can define that as separate property. Without it, depending on how your state treats marital debt and whether new debt is taken on during the marriage, the other spouse could face collection exposure they never agreed to. This isn't theoretical; it shows up in divorce cases regularly.
Income trajectory matters more than current income. A resident physician making $65,000 a year looks like a modest earner. Four years later, that same person may be making $350,000. A prenup signed before the marriage can establish that the future earning premium doesn't automatically get split under equitable distribution doctrine. Same logic applies to a partner who's a year away from a software engineering role, a licensed electrician building a client base, or anyone whose current income dramatically underrepresents their earning ceiling.
Expected inheritance is often the most overlooked trigger. If either partner has a parent or grandparent with meaningful assets, and that inheritance is likely within a foreseeable timeframe, a prenup that designates inherited assets as separate property can prevent those funds from becoming marital property if they're later commingled with joint accounts. Once inheritance money gets deposited into a joint account and spent down and replaced over years, tracing it as separate property in a divorce is expensive and often unsuccessful.
Business ownership or entrepreneurial plans round out the short list. If one partner plans to start a business during the marriage, a prenup can define what percentage of that business, or what type of equity, remains separate property. Without that, a spouse who had nothing to do with building the business may have a legitimate equitable distribution claim against it.
When You Probably Don't Need One
This article isn't for everyone considering marriage. If both partners have minimal debt, similar and stable income levels, no business interests, and no significant inheritance expected from either family, the financial logic for a prenup is genuinely thin. That's not a cop-out. That's an honest assessment of when the cost doesn't return value.
Short marriages also change the calculus. Equitable distribution in most states looks at the length of the marriage when dividing assets. A couple that divorces after two years with no significant asset accumulation may find a court reaches a similar outcome to what a prenup would have specified anyway, making the agreement redundant in retrospect.
The alternative to a prenup in low-stakes financial situations isn't nothing, though. It's a detailed, written financial conversation before marriage that covers debt ownership, how income will be managed during the marriage, and what happens to any inheritance either partner receives. That conversation doesn't have legal enforceability, but it reduces the chance of the ambiguity that makes divorces expensive. Some couples also use a cohabitation agreement (if they're living together before marriage) to handle the pre-marital period, then revisit legal documentation when their financial circumstances actually change.
How to Get a Prenup That Holds Up
A prenup that gets thrown out in court is worse than no prenup. Courts have overturned agreements for several reasons that are entirely avoidable: one spouse didn't have independent legal representation, the agreement was signed within days of the wedding (courts sometimes treat this as signing under duress), or material financial information was not fully disclosed by both parties. These aren't technicalities. They reflect the doctrine that a contract is only enforceable when both parties entered it knowingly and voluntarily.
The practical requirements: both partners need their own separate attorneys. Not the same attorney. Not one attorney advising both. Each person should have independent counsel review and ideally help negotiate the terms. This is the single most important factor in whether a prenup survives a challenge, according to the American Bar Association's family law guidance. Sign well before the wedding, ideally several months out. Complete financial disclosure from both sides must be documented and attached to the agreement.
Cost-reduction options exist without sacrificing validity. Some couples use online legal services to generate a first draft, then have separate attorneys review and revise it rather than draft from scratch. That can bring costs down meaningfully. It's not the same as having an attorney draft the agreement from your specific circumstances, but for a straightforward situation, it may be adequate. I'd start with a consultation from a family law attorney in your state before choosing this route, since enforceability standards vary by jurisdiction and a $300 review is worth it before signing something intended to hold up under litigation.
One thing that won't save money: having both partners share a single attorney. It looks cheaper, but it eliminates the independent representation that courts expect to see. If the agreement is ever challenged, that shared-counsel fact will be front and center.
The Default You're Already Accepting
Every couple that marries without a prenup has implicitly signed one already. It's called their state's divorce statute.
Community property states (California, Texas, Arizona, Nevada, and a handful of others) generally treat most assets and debts acquired during the marriage as equally owned by both spouses. Equitable distribution states (the majority) divide marital property based on what a court determines is fair, which is a standard with significant judicial discretion built in. Neither framework is wrong, but neither was written with your specific financial situation in mind.
If you skip the prenup conversation and the marriage ends in divorce, a judge will apply those default rules to your circumstances. That might produce a reasonable outcome. It might not. What it won't produce is the outcome you would have chosen if you'd sat down together and decided. The couples who regret not having a prenup rarely regret it on their wedding day. They regret it when they're sitting across from their ex in a mediator's office arguing about a business one of them built, a debt the other one ran up, or an inheritance that ended up in a joint account years ago.
Skipping the prenup conversation doesn't keep legal exposure out of your marriage. It just leaves that exposure undefined until a court defines it for you.
Should You Get One?
If you have significant debt on one side, a diverging income trajectory, a likely inheritance, or plans to start a business during the marriage, get the prenup. The cost is real but it's a fraction of what a contested divorce costs, and the enforceability conditions aren't difficult to meet if you start early and both partners have counsel.
If none of those conditions apply and both partners have roughly equivalent, stable financial situations, the cost-benefit math genuinely may not work in your favor. Have the financial disclosure conversation anyway, write it down even if it's not legally binding, and revisit the question if your circumstances change.
The one thing worth avoiding is making this decision based on a default assumption that prenups are only for wealthy people. That assumption has a specific cost. It leaves the couples who need protection most because they're carrying debt, building something, or expecting inheritance in a legally undefined position, and it leaves state divorce courts to sort it out later.
