For simple finances (both W-2 earners, one house, no business, no kids from before), an online prenup at $599–$649 delivers the same enforceable document as a $3,000–$10,000 attorney job — the law checks process, not price. The moment a business, multiple properties, big inequality, or support waivers enter, pay for lawyers. The line between the two is sharper than either side's marketing admits.
Both sides of this industry have a marketing problem: lawyers say online is reckless, online services say lawyers are dinosaurs. The truth is a clean line drawn through the middle of your finances — and you can find your side of it in about two minutes.
The price reality (2026 numbers)
| Path | Cost per couple | Timeline | Attorney for each partner? |
|---|---|---|---|
| Free template | $0 | A day | No |
| Online self-serve | $599–$649 flat | Hours to draft, days to sign | No |
| Online + attorney review | ~$2,000–$3,500 flat | 1–3 weeks | Yes |
| Traditional two-attorney | $3,000–$10,000+ (hourly at ~$344/hr avg) | 1–3 months | Yes |
Read the middle two rows again. The online tier with a real lawyer reviewing both sides lands at roughly the price of one-third of an hourly attorney engagement — with the same enforceability fundamentals built into the process.
What the law actually cares about
Every state asks the same five questions (see Is an Online Prenup Legally Valid?):
- Full financial disclosure, in writing?
- Signed voluntarily, with time to think?
- Before the wedding?
- State formalities (notary/witnesses) followed?
- Terms not unconscionable at signing?
Notice what’s missing: who drafted it. A $599 platform agreement that passes five checks beats an $8,000 attorney draft that misses one. And platforms are structurally good at this — they force disclosure before proceeding and walk through your state’s signing ceremony step by step.
Where online genuinely wins
- Standard situations, executed well. The guided questionnaires exist because 80% of couples need the same 12 clauses: separate property, the house, debts, business (simple), support terms, death provisions.
- Speed without sloppiness. Draft in an evening vs. three months of scheduling. Fewer months before the wedding = less time pressure = a stronger agreement.
- Price transparency. Flat fee, known upfront, no meter running while you think. The #1 complaint about hourly billing isn’t the total — it’s the unpredictability.
- Both partners equally in the loop. Each spouse has their own login and answers the same questions. Nobody drafts “their” agreement and hands it over — which, not coincidentally, is also better for enforceability.
Where lawyers genuinely win
- Anything with a valuation or a nuance. Business equity that will grow during the marriage, real estate in two states, a trust, stock options, expected inheritance — drafting choices get subtle, and subtle is where templates have edges.
- Asymmetric power. When one spouse has vastly more assets or income, a template’s defaults may be unfair in ways a court later questions — or unfair to you in ways you didn’t notice. Counsel is cheap insurance against both errors.
- States with hard requirements. California won’t enforce a spousal-support waiver unless each party had independent counsel and received the final draft 7+ days before signing. Several states effectively demand representation for certain clauses. Your state’s rulebook decides, not your budget.
- Negotiation with a counterpart. If your fiancé has an attorney, you want one too. Two lawyers negotiating is slow and expensive — but one lawyer negotiating against nobody is how bad terms sneak through.
The 7-question test (circle your answers)
An online service is enough when all seven apply:
- ☐ Both spouses earn regular W-2/salary income
- ☐ No business interests — now or planned
- ☐ One home, in one state (or none)
- ☐ No children from previous relationships
- ☐ No expected inheritance or family trust
- ☐ No huge gap in assets between you
- ☐ You both agree on the terms without an ultimatum
Seven yeses → online, flat fee, done. One or more noes → either online plus attorney review, or full representation. Two or more noes involving money or power → hire lawyers.
The hybrid move nobody regrets
The industry quietly converged on the same play: platform for structure, lawyer for judgment.
You and your partner complete the questionnaire and disclosures together (evenings, flat fee). Then each of you adds an attorney review of the finished draft — roughly $699–$799 per partner on today’s platforms versus $3,000–$10,000+ of hourly work. You’re paying lawyers the right way: to think about your document, not to type it.
That’s not a compromise between the two options. It’s what both options look like when you strip out what you’re not paying for.
The bottom line
If your finances fit the seven yeses, a lawyer’s primary contribution to your prenup would be a larger invoice. If they don’t, an online service’s primary contribution would be a false sense of completion. Know which sentence describes you — then stop shopping and start signing.
