The best online prenup service depends on whether you need attorney representation, a guided agreement, or ongoing access to broader legal services. CNBC Select’s September 16, 2026 comparison names Neptune, HelloPrenup, LegalShield, Clause, and Rocket Lawyer for different use cases—not as universal endorsements. Compare the total cost, attorney involvement, state availability, and signing support before choosing.
How to compare online prenup services
These services use different pricing and support models, so their advertised prices are not directly equivalent. Before paying, check:

- Total cost: Is the fee flat, a recurring subscription, or a bundle? If you subscribe, how long might you need the service?
- Attorney involvement: Does a lawyer prepare or review your particular agreement? Does each partner have separate counsel?
- Scope: Who drafts the document, what edits are included, and are financial disclosures or custom clauses supported?
- Signing: Are execution guidance, witnesses, or notarization included or extra?
- Availability: Does the service support your state, and does the agreement address the relevant state’s requirements?
- Broader value: A legal subscription may make sense if you expect to use its other services, but may cost more than a one-time option if you only need a prenup.
The figures below are those reported in CNBC Select’s September 16, 2026 comparison, except where an official provider page is specifically identified. Offers and terms can change; confirm them directly before enrolling. CNBC Select’s comparison

Neptune: a guided starting point with attorney support
CNBC Select describes Neptune as an option for couples who have not yet settled on what they want in a prenup. It reports an AI chatbot, attorney selection, drafting and review, notarization coordination, and a $5,000 bundle that includes two attorneys. Since the bundle costs substantially more than the other figures in this comparison, confirm what the current package covers and whether a la carte options better match your needs. CNBC Select

HelloPrenup: a flat-fee online agreement, with attorney support as an upgrade
HelloPrenup’s pricing page lists a $599-per-couple state-specific online prenup with guided questionnaires, financial disclosures, and unlimited edits. That base tier does not include an attorney working on the couple’s specific agreement. The page also lists a $49 attorney Q&A, $50 e-notarization add-on, and a $2,197 package with separate attorney representation for both partners. HelloPrenup says it is available in 49 states and is not yet live in West Virginia; check current availability and terms. HelloPrenup pricing
LegalShield: consider it as a broader legal subscription
CNBC Select characterizes LegalShield as a general legal subscription rather than a prenup-only platform and reports monthly tiers of $39.95, $49.95, and $59.95. Its potential value depends on whether you will use other covered legal-plan services. Read the plan details and exclusions carefully: the comparison notes that not every existing legal situation is covered. CNBC Select
Clause: collaboration-focused preparation
CNBC Select highlights Clause for partner collaboration and describes guided questions and financial-disclosure tools. It reports a $549 basic package and a $699 full-protection package. The comparison does not establish exactly which package includes notarization or attorney review, or the scope of any custom-clause feature, so verify those details before choosing. CNBC Select

CNBC Select reports a seven-day trial followed by subscription options of $19.99 or $39.99 per month, alongside access to a wider range of legal services.

What is a prenup, and what should it address?
A prenuptial agreement is a written agreement made before marriage that sets out how the couple will handle certain financial matters. The relevant terms and legal requirements depend on the state and on what the agreement says. The service pages and comparison cited here do not establish a universal list of matters every prenup can or should cover, so do not assume an online template can resolve every issue. For questions about a particular clause or its legal effect, speak with an attorney licensed in the relevant state. LegalZoom’s prenup guidance
Why the drafting tool does not determine whether an agreement will hold up
Using an online service does not guarantee enforceability or a particular court outcome. LegalZoom’s guidance says both partners should disclose assets, debts, income, and obligations; sign voluntarily; and allow time to review and seek counsel. It also notes that many states require a written agreement and witnessing or notarization, while requirements vary by state and can depend on the clauses involved. LegalZoom’s prenup guidance
Rank #4
- Used Book in Good Condition
Start the conversation early enough that both people can consider the terms without being rushed. Consider advice from a lawyer licensed in the relevant state, particularly if you have significant or complicated assets, business interests, a proposed spousal-support waiver, cross-state concerns, or a wedding date approaching soon. An attorney can advise on your circumstances; a questionnaire or document generator cannot substitute for that judgment.
