How Much Does a Prenup Cost in 2026? The Full Price Guide
You ask three people what a prenup costs and you get three completely different answers. One says $599. Another says $8,000. A third says $10,000 or more. They can all be right, because they are talking about different products.
A prenup, short for prenuptial agreement, is a written contract signed before marriage. It sets out what happens to property, debts, businesses and sometimes spousal support if the marriage ends. The price depends on who drafts it, how complicated your finances are, where you live, and how much the two sides negotiate.
All prices below were checked on Nov 2, 2026, from ThisFirst, LegalClarity, ThePricer, HelloPrenup, ContractsCounsel and the Clio 2025 Legal Trends Report. Prices are US prices and will vary by state and by firm. This guide is general information, not legal advice.
The Quick Answer
Most couples pay in one of three bands. An online prenup costs $599 to $2,197 per couple. A straightforward attorney-drafted prenup costs $1,500 to $3,000. A typical two-attorney prenup, where each partner hires their own lawyer, costs $3,000 to $10,000 or more per couple.
The survey average most often quoted is about $8,000 per couple, from a survey of family law attorneys reported by HelloPrenup and LegalClarity. That figure covers both partners' lawyers combined, not one lawyer alone. It is an average, not a typical bill: simple couples pay far less, and couples with businesses or trusts pay far more.
Why the Ranges Disagree So Much
The single biggest source of confusion is what the price covers. A $599 price usually covers one shared online document for both partners, with no individual lawyer representing either side. An $8,000 figure usually covers two separate lawyers, each advising one partner, plus negotiation and revisions.
| What the price usually covers | Typical price per couple | Who is represented |
|---|---|---|
| Online self-serve document, no attorney | $599–$999 | Neither partner individually |
| Online document plus attorney review | $2,197–$3,500 | Both partners, limited scope |
| One attorney drafts, other partner reviews | $1,500–$5,000 | One fully, one for review |
| Two traditional attorneys, hourly | $3,000–$10,000+ | Both partners fully |
| High-net-worth or business prenup | $7,000–$20,000+ | Both partners, plus advisers |
Prenup Cost by Complexity
Complexity is the main price driver after the route you choose. A couple renting a flat with no children, no business and similar incomes is a simple case. Add a house, retirement accounts, a small business or a trust, and the hours — and the bill — rise.
| Situation | Typical total per couple | What makes it cost more |
|---|---|---|
| Simple: few assets, no business, little debt | $1,500–$3,000 | Basic disclosure and standard terms |
| Moderate: a home, retirement accounts, a small business | $3,000–$7,000 | Valuations, business terms, negotiation |
| High complexity: multiple properties, trusts, equity, family business | $7,000–$15,000+ | Multiple advisers, long negotiation |
| Very high net worth or international assets | $10,000–$20,000+ | Tax, trust and cross-border advice |
Family law attorneys typically charge $250 to $1,000 an hour, according to LegalClarity, and the Clio 2025 report puts the average at $344 to $349. At $350 an hour, ten hours is $3,500 — before the second lawyer's bill. That is why two-attorney prenups climb so fast: you are paying for two professionals, not one.
Online vs Attorney: What You Actually Get
Online platforms are the cheapest route, and for some couples they are enough. HelloPrenup charges $599 per couple for its online agreement, with optional electronic notarisation for $50 and a 20-minute attorney question session for $49, according to ThePricer. Its two-attorney package costs $2,197 per couple. ThisFirst, another flat-fee platform, starts at $649 per couple for self-serve and charges $3,500 for lawyer review for both partners.
Attorney-drafted prenups cost more because a lawyer tailors the agreement to your state's rules, checks your financial disclosure, and negotiates terms the other side may resist. That matters because a prenup is only useful if a court enforces it. A cheap agreement that gets thrown out in divorce costs far more than an expensive one that holds up — a point LegalClarity makes bluntly, and it is correct.
ContractsCounsel, a lawyer marketplace, reports an average draft price of $890 and an average review price of $540. Those figures sit between pure online and full two-attorney pricing, and they suit couples who want a real lawyer involved without paying for two full hourly engagements.
Prenup Cost by State: Tier, Not a 46-State List
Rates follow local wages, so the same prenup costs more in an expensive city than in a cheaper one. ThisFirst already publishes a 46-state table, so this guide does the more useful thing: it groups states into tiers so you can place yourself in seconds.
| Tier | Examples | Two-attorney prenup, typical range |
|---|---|---|
| Highest cost | California, New York, Massachusetts, Washington DC | $6,000–$12,000+ |
| High cost | New Jersey, Connecticut, Illinois, Washington | $5,000–$10,000 |
| Mid cost | Texas, Florida, Georgia, North Carolina, Colorado | $3,000–$7,000 |
| Lower cost | Ohio, Indiana, Missouri, Alabama, Oklahoma | $2,000–$5,000 |
Worked Example: Three Couples, Three Bills
Maya and Tom rent, have no children, and earn similar salaries. They use an online platform at $599, add electronic notarisation at $50, and pay $49 for a short attorney question session. Total: $698.
Priya and Dan own a house, have retirement accounts, and Dan owns a small business. Each hires a lawyer. Priya's lawyer bills 8 hours at $350, which is $2,800. Dan's lawyer bills 9 hours at $350, which is $3,150. Add a business valuation of $800 and notarisation of $50. Total: $6,800.
Alex and Jordan have multiple properties, a trust and equity in a family company. Their two lawyers bill 25 hours combined at $400 an hour, which is $10,000, plus $1,500 for valuations and $500 for a trust review. Total: $12,000.
The lesson is simple: the bill follows the hours, and the hours follow the complexity and the amount of negotiation.
Hidden Costs to Budget For
Attorney fees are not the only expense. Asset appraisals can cost several hundred dollars each. A forensic accountant, needed when one side suspects hidden assets, costs far more. Notarisation is usually $25 to $50, or $50 for electronic notarisation at HelloPrenup. Changing the agreement later is cheaper than drafting from scratch: LegalClarity puts review and revision of an existing prenup at $500 to $2,000 for straightforward changes, though a full renegotiation can cost nearly as much as the original.
How to Keep the Cost Down
Agree on the big questions before you hire anyone: what stays separate, what is shared, and how debts are handled. Gather your financial documents before the first meeting, so you are not paying $350 an hour for paperwork you could have organised at home. Ask whether the lawyer offers a flat fee, and exactly what it covers. Get independent advice for both partners if you can afford it; one lawyer cannot properly represent both sides.
Frequently Asked Questions
How much does a prenup cost on average?
About $8,000 per couple, according to a survey of family law attorneys reported by HelloPrenup and LegalClarity. That average covers both partners' lawyers combined. Simple couples often pay $1,500 to $3,000, while complex cases can exceed $10,000.
Is a $599 online prenup legally valid?
It can be, if it meets your state's requirements: written, signed by both parties, with full financial disclosure and no pressure to sign. But an online document gives neither partner individual legal advice, which makes it easier to challenge later than an attorney-drafted agreement.
Do both partners need their own lawyer?
It is strongly recommended, and in practice it is the standard approach. Each partner having independent counsel makes the agreement far harder to challenge. One lawyer should not be assumed to represent both partners.
How long does a prenup take to make?
An online prenup can be done in days. An attorney-drafted prenup usually takes one to three months, including disclosure, drafting, review and negotiation. Complex cases can take two to six months.
Can a prenup be changed after marriage?
Yes. A couple can amend a prenup, or sign a postnuptial agreement after marriage. Straightforward revisions typically cost $500 to $2,000, according to LegalClarity, though major renegotiation costs more.
