HelloPrenup Review: $599 for a Prenup, and the Four Things That Decide Whether It Holds

HelloPrenup builds state-specific prenuptial agreements online for $599, with $49 attorney Q&A sessions and $50 e-sign and notarization. What decides enforceability is disclosure, timing, voluntariness and independent counsel - not the document.

HelloPrenup is an online platform for creating prenuptial agreements, built collaboratively with your partner, tailored by state, and covering all 50 states plus DC and an international option. It also offers postnuptial agreements. Verified pricing: $599 to build your own state-specific prenup with your partner. $49 per 20-minute attorney Q&A session, per partner, if you want to ask a lawyer a question. $50 to add e-sign and notarization — available in every state except Mississippi, Vermont, Maryland and Wisconsin. Full attorney document review and attorney representation are available as paid add-ons at what the company describes as negotiated discounted rates, and a free consultation is offered. A $699 figure also appears on the site. Against traditional prenup costs — commonly $2,500 to $10,000 or more for two attorneys — that is a large saving, and prenups being unaffordable is a real problem that this addresses. But the document is the easy part. Whether a prenup survives a challenge is decided by four things, and only one of them is the paperwork. That is what this review is about.

The four things that decide whether a prenup holds

Courts set prenups aside more often than people expect, and the reasons are consistent. Here they are. 1. Full and fair financial disclosure. Both parties must disclose assets, debts, income and expectations honestly and completely, usually in a schedule attached to the agreement. Hiding an account, understating a business's value, or omitting a debt is the most common route to a prenup being thrown out — and it is entirely avoidable. Over-disclose. Attach statements. If you are not sure whether something counts, include it. 2. Voluntariness — no duress, no coercion. An agreement signed under pressure is vulnerable. The classic fact pattern that gets prenups invalidated is presenting one days before the wedding, when the other party faces the choice of signing or cancelling a wedding their family has flown in for. Courts see that for what it is. 3. Timing, which is a formal requirement in some states. California requires at least seven calendar days between when a party is first presented with the final agreement and when they sign it — and that period cannot be waived. Other states apply a general reasonableness test. Sign months before the wedding, not weeks. If you are inside a month, that alone is a reason to slow down. 4. Independent legal representation. This is the single strongest protection against a later challenge. Each party having their own attorney — not a shared one — makes it very difficult to argue afterwards that you did not understand what you signed. In California, a party who was not represented by independent counsel must have expressly waived that representation in a separate signed writing, and there are further requirements about being informed of the terms and effects in a language they understand. Which brings us to the honest assessment of the model. HelloPrenup gives you the document and a route to attorney add-ons. The add-ons are where the enforceability protection lives, and a couple that buys the $599 document and skips them has saved money on the part that is cheap to get right and economised on the part that is not. Two things a prenup cannot do, whoever drafts it: It cannot determine child custody or child support. Courts decide those on the best interests of the child at the time, and any clause purporting to fix them in advance is generally unenforceable. It cannot be unconscionable. Terms that leave one party destitute while the other keeps everything can be set aside, particularly if circumstances have changed dramatically.
  • Requirement | Why it matters | What to do
  • Full financial disclosure | Most common reason prenups are set aside | Over-disclose; attach statements
  • Voluntariness | Duress invalidates | Do not present it close to the wedding
  • Timing | California requires 7 days, unwaivable; others test reasonableness | Sign months ahead
  • Independent counsel each | The strongest protection against challenge | Budget for it - this is where the money should go
  • Cannot fix child custody or support | Court decides on best interests | Do not try
  • Cannot be unconscionable | Can be set aside | Keep terms defensible

A prenuptial agreement cannot determine child custody or child support - courts decide those on the child's best interests regardless of what an agreement says. Signing shortly before a wedding is the most common ground for a later challenge; California requires a minimum seven-day review period that cannot be waived, and other states apply reasonableness tests. Sign months ahead, not weeks.

What HelloPrenup does well

Several things here are genuinely good, and the access argument is the strongest of them. Price and access. Prenups are expensive enough that most couples who would benefit from one never get one. At $599 against $2,500 to $10,000+ for two attorneys, this changes who can realistically have one. That is a real public good, and it is the reason to take the platform seriously rather than dismiss it. State-specific drafting. Prenup law is state law and it varies substantially — community property versus equitable distribution, the specific execution formalities, what can and cannot be waived. A generic template downloaded from anywhere is a poor foundation. Covering all 50 states plus DC with state-tailored documents is the correct approach. Collaborative building. Both partners work through the agreement together rather than one presenting a finished document to the other. This is more than a convenience feature — it directly addresses the voluntariness and duress question, and it produces a better conversation. E-sign and notarization at $50. Genuinely useful, with an honest disclosure that it is not available in Mississippi, Vermont, Maryland or Wisconsin. Stating the exceptions plainly is a good sign. Attorney access as an add-on. $49 for a 20-minute Q&A per partner is a low barrier to getting a specific question answered, and full review and representation are available. The company states it has negotiated discounted rates with family law attorneys. A large body of free educational content — a prenup guide, encyclopedia, clause explanations, notarization basics, a podcast and state-by-state pages. Whatever you decide about the product, that content is useful and free. What we could not verify: whether the attorneys in the network are licensed in every state, what "reviewed, approved, or partnered with" means precisely for the attorneys cited, the refund policy, and what happens if you start and do not finish. Ask before paying.

Budget for independent attorney review for each partner, not just the document. The document is the cheap part; the review is what makes it hard to challenge later - and $599 plus two reviews still costs far less than two attorneys drafting from scratch.

Having the conversation, which is the actual hard part

Most of the difficulty with prenups is not legal. It is that the conversation is uncomfortable, and how it is raised determines how it goes. Raise it early and not as an ultimatum. The worst version is: engaged, venue booked, and one partner produces a document. The best version is a conversation about money and expectations before the engagement is far advanced — one that would have been worth having anyway. Frame it as what it is: a plan for the unexpected, made while you like each other. Couples plan for illness with insurance and death with wills without concluding the marriage is doomed. A prenup is the same category of act, and it is also a set of default rules that already apply to you. Getting married means entering a financial arrangement written by your state legislature. A prenup is choosing your own terms instead of accepting the default ones. Who benefits most: Anyone with significantly unequal assets or debts entering the marriage — including student debt, which many people do not realise is worth addressing. Business owners, especially with partners or investors, where a divorce can otherwise force a valuation or a sale. Second marriages, particularly with children from a previous relationship. This is one of the strongest cases — protecting children's inheritance is a legitimate and common goal. Anyone expecting a significant inheritance. Couples where one will step back from paid work to raise children. This one is counterintuitive: a well-drafted prenup can protect the lower-earning partner by specifying support, rather than leaving them to argue for it later. Couples with international assets or differing citizenship. What to discuss, concretely: what each of you brings in, how income earned during the marriage is treated, what happens to the home, how debt is handled, whether spousal support applies and on what terms, and how any business or inheritance is treated. Have that conversation before you open a platform. A postnuptial agreement — offered here too — covers the same ground after marriage. It is a genuine option if you missed the window, though it can face more scrutiny in some states because the "walk away" option no longer exists.

Raise a prenup before the engagement is far advanced, not after the venue is booked. Timing is both a legal requirement in some states and the single biggest factor in whether the conversation goes well - and a document produced weeks before a wedding is the fact pattern courts most often set aside.

Frequently asked questions

How much does HelloPrenup cost? $599 to build a state-specific prenup with your partner. Attorney Q&A sessions are $49 per 20 minutes per partner, e-sign and notarization is $50, and full attorney review and representation are available as add-ons. A $699 figure also appears on the site — confirm what applies to you. Is an online prenup enforceable? Enforceability depends on full financial disclosure, voluntary signing without duress, adequate timing, and — critically — whether each party had independent legal representation. The document itself is only one factor. Do we each need our own lawyer? It is the strongest protection against a later challenge. In California, a party without independent counsel must have expressly waived representation in a separate signed writing, with further requirements. Budget for it. How far in advance should we sign? Months, not weeks. California requires at least seven calendar days between first presentation of the final agreement and signing, and that period cannot be waived. Other states apply reasonableness tests. Does it need to be notarized? Requirements vary by state. HelloPrenup offers e-sign and notarization for $50, available everywhere except Mississippi, Vermont, Maryland and Wisconsin. Can we decide child custody or support in it? No. Courts decide those on the best interests of the child regardless of what the agreement says. Can a prenup be thrown out? Yes — most commonly for incomplete financial disclosure, duress, inadequate timing, lack of independent counsel, or unconscionable terms. Is a postnup as good? It covers the same ground after marriage and is a real option, though it can face more scrutiny in some states. Who benefits most from a prenup? Anyone with unequal assets or debts, business owners, second marriages with children, those expecting inheritances, couples where one will step back from paid work, and couples with international assets. Does a prenup mean we expect to divorce? No more than insurance means you expect a fire. Marriage already imposes a financial arrangement written by your state; a prenup is choosing your own terms instead.

The Bottom Line

Our rating: 8 / 10. A genuinely valuable service that makes prenups affordable, provided you spend some of the savings on the part that actually protects you. The access argument is strong and should be said first. Prenups cost $2,500 to $10,000 or more with two attorneys, which means most couples who would benefit never get one. At $599 for a state-specific, collaboratively built agreement — with state law genuinely varying and generic templates being a poor foundation — this changes who can realistically have one. The collaborative build is more than convenience: it directly addresses the voluntariness question that gets prenups challenged. E-sign and notarization at $50, with the four excluded states stated plainly, is honest disclosure. And the free educational content is substantial and useful whether or not you buy. The reservation is where couples will be tempted to economise. Enforceability is decided by four things: full financial disclosure, voluntary signing, adequate timing, and independent legal representation for each party. Only the document is cheap. A couple who buys the $599 agreement and skips attorney review has saved money on the easy part. Budget for a review each — $599 plus two reviews still costs a fraction of two attorneys drafting from scratch, and the $49 Q&A sessions are a sensible low-cost entry point. Two hard rules regardless of who drafts it. Sign months before the wedding, not weeks — California mandates a seven-day minimum that cannot be waived, and a document produced close to the date is the fact pattern courts most often set aside. And over-disclose financially; incomplete disclosure is the most common reason a prenup fails. And know its limits: no prenup can determine child custody or child support. Courts decide those on the child's best interests, whatever the document says. Check HelloPrenup's current pricing and state coverage Informational only and not legal advice.
