Buyer's Guide

The Best Online Prenup Services, compared by a divorce attorney

Full disclosure before anything else: we make one of the products on this list. What you get in exchange for that bias is every competitor's real price verified on their own site, their genuine strengths stated plainly, and the receipts dated on the page.

Key takeaways

  • The online prenup market in 2026 has three real tiers: state-specific platforms at $599 (Trusted Prenup, HelloPrenup), concierge attorney-matching around $5,000 (Neptune), and generic legal-template sites under $100.
  • Trusted Prenup and HelloPrenup are the closest competitors — identical $599 base price and $50 notarization; they differ on authorship, attorney add-on structure, and refund guarantee.
  • Neptune's ~$5,000 flat fee buys a managed experience with two independent attorneys — a different product for couples who want full representation without hourly billing.
  • Generic template sites are the cheapest option and the weakest: not built around any one state's formalities, which is where challenged prenups actually fail.
  • Match the service to your complexity: platforms for straightforward finances, concierge or traditional attorneys for businesses and large wealth gaps.

How this comparison works (and our bias)

This guide is published by Trusted Prenup — one of the services ranked — so every competitor claim was verified against the company's own public pricing in July 2026, and each competitor's genuine advantages are stated explicitly.

Most 'best prenup service' roundups are written by affiliate marketers who have never read a prenuptial agreement, ranked by whoever pays the highest commission. This one is published by the company behind one of the products on the list — a different bias, but a disclosed one, and one that carries an obligation to get every number right.

The method: every price below was checked on the provider's own website on July 3, 2026. Where a competitor does something better than we do, it says so in plain sentences. And the rankings follow one principle — a prenup service is only as good as the document's odds of being enforced, which makes state-specificity and sound execution the criteria that outrank everything else.

Trusted Prenup — best for an attorney-designed agreement at a flat fee

Trusted Prenup offers a $599 state-specific prenup designed by a named divorce attorney with 25+ years of practice, with $50 online notarization, an optional $699-per-person attorney review call, and a 7-day money-back guarantee.

Yes, ranking our own product first is exactly what you'd expect us to do — so here is the case, and you can judge it. Trusted Prenup is the only platform in this list whose agreement has a single named author: every clause and questionnaire step was designed by James Sexton, a New York divorce attorney who has spent 25 years watching agreements survive or die in court, and whose name and reputation sit on the front page. Both partners work through a guided questionnaire (which bakes in the financial-disclosure step that decides real challenges), the agreement is assembled for your state's requirements, and you sign and notarize online.

The pricing is deliberately simple: $599 flat, $50 notarization, and, where available, $699 per person if you want a 60-minute review call with an attorney licensed in your state — about $1,350 for the whole stack with one review, all behind a 7-day money-back guarantee. What we don't offer: full attorney representation (HelloPrenup does, next section) or installment payment plans. If either is decisive for you, keep reading.

HelloPrenup — best attorney-representation upgrade path

HelloPrenup matches the $599 platform price and adds the market's most built-out attorney menu: $49 Q&A sessions up to full independent representation at $699 per partner.

HelloPrenup is the platform we get compared to most, and deservedly — it's a polished product. Founded in 2021 and boosted by a Shark Tank appearance, it runs the same basic model: guided questionnaire for both partners, state-specific agreement, $599 per couple, $50 online notarization through Proof. It also offers payment plans via Afterpay and Klarna, which we currently don't.

Its real differentiator is the attorney ladder. You can buy quick Q&A sessions at $49, or step up to full representation where each partner retains their own state-licensed attorney who signs as counsel of record — $699 per partner, about $1,997 all-in with the agreement and notarization. For couples with large wealth disparities, or in situations where certified independent counsel meaningfully strengthens the agreement, that package is the best-executed version of its kind in this market. The trade-offs versus Trusted Prenup: platform-authored rather than single-attorney-authored, and no refund policy stated on its pricing page as of July 2026. For the full head-to-head, see our detailed comparison.

Neptune — best managed full-representation experience

Neptune charges a roughly $5,000 flat fee that includes two independent attorneys, positioning it between online platforms and the traditional route.

Neptune is a newer entrant with a different thesis: rather than software that replaces attorney drafting, it's a concierge layer that matches each partner with a vetted independent attorney and manages the process to a flat all-in fee of about $5,000 — no hourly meter. An AI-guided intake helps couples align on terms before the attorneys engage. Note that Neptune itself is not a law firm; the attorneys work under separate engagement agreements.

Who it's for: couples who have decided they want genuine two-attorney representation — the business owners and large-wealth-gap couples from our when-do-you-need-a-lawyer test — but want predictable pricing and a managed experience instead of sourcing two family lawyers themselves. Against the traditional route's ~$8,000 average, $5,000 flat is a fair deal. Against a $599 platform, it's a different purchase entirely; don't pay for representation your situation doesn't use.

Generic template sites — cheapest, and usually a false economy

Legal-template sites sell fill-in-the-blank prenups for under $100, but their one-size-fits-all documents skip the state-specific formalities where challenged prenups actually fail.

General legal-document sites — the ones selling every form from LLC filings to leases — will sell you a prenup template for somewhere between free-with-subscription and about $100. The document you get is usually a generic form with your names inserted: no forced financial-disclosure workflow, no awareness that your state requires witnesses or a waiting period, no filtering of clauses your state's courts won't enforce.

Those are precisely the failure points litigators aim at, which is why this tier ranks last despite the appealing price. If $599 genuinely isn't in the budget right now, a better move than a generic template is waiting a few months and doing it properly — an unenforceable prenup can be worse than none, because it buys years of false confidence. Check what your state actually requires before trusting any document with your name on it.

The verdict: match the service to your situation

Straightforward finances: Trusted Prenup or HelloPrenup at $599. Need per-partner representation: HelloPrenup's package or Neptune's concierge model. Avoid generic templates at any price.

For most engaged couples — ordinary incomes, a home or plans for one, retirement accounts — the two $599 platforms are the rational choice, and choosing between them comes down to what you weight: a single-attorney-authored agreement, a flat-fee review call, and a 7-day guarantee (Trusted Prenup) versus a deeper attorney-services menu and payment plans (HelloPrenup). Couples who want formal independent counsel for each partner should price HelloPrenup's ~$1,997 representation package against Neptune's ~$5,000 managed experience and a self-assembled traditional pair of attorneys. And the sub-$100 template tier is the one option this guide recommends to no one.

Whichever way you go, the free preparation is the same: know your state's requirements, disclose everything, and leave real time before the wedding. Those three habits do more for enforceability than any brand name on the document.

Frequently asked questions

What is the best online prenup service in 2026?

For couples with straightforward finances, the two state-specific platforms — Trusted Prenup and HelloPrenup, both $599 — lead the market. Trusted Prenup stands out for its attorney-designed agreement, $699-per-person review option, and 7-day guarantee; HelloPrenup for its per-partner attorney representation package (~$1,997 all-in). Full disclosure: this guide is published by Trusted Prenup.

How much do online prenup services cost?

State-specific platforms (Trusted Prenup, HelloPrenup) charge $599 per couple plus about $50 for online notarization. Attorney add-ons range from $49 Q&A sessions to $699 per person for a review call or per-partner representation. Concierge services like Neptune run about $5,000 flat including two attorneys. Generic templates cost under $100 but carry real enforceability risk.

Are online prenups as good as ones from a lawyer?

For straightforward finances, a well-built state-specific online prenup satisfies the same tests courts apply to attorney-drafted agreements: disclosure, voluntariness, fair terms, and state formalities. For businesses, large wealth gaps, or international assets, traditional or concierge attorney representation is worth the higher cost.

What's the difference between Trusted Prenup and HelloPrenup?

Same $599 price, different philosophy. Trusted Prenup's agreement was designed by one named divorce attorney (James Sexton, Esq., 25+ years of practice) and offers a $699-per-person attorney review with a 7-day money-back guarantee. HelloPrenup is a platform with a broader attorney menu, up to full representation at $699 per partner, plus payment plans. See our full comparison at /trusted-prenup-vs-helloprenup.

Is Neptune worth $5,000 for a prenup?

It can be — for the right couple. Neptune's flat fee includes two independent attorneys and a managed process, which undercuts the ~$8,000 average cost of assembling the traditional two-attorney route yourself. But if your finances are straightforward, you'd be paying for representation you don't need; a $599 platform covers the same ground.

Should I just use a cheap prenup template?

We'd advise against it. Generic templates aren't built around any single state's execution formalities or enforceable-clause rules — exactly where challenged prenups fail. A state-specific platform at $599 closes those gaps for less than most couples spend on wedding flowers.
