Neptune vs HelloPrenup: which prenup service should you use?
HelloPrenup's base price is a self-guided document builder: no attorney reviews your specific agreement unless you add representation separately, for a per-partner fee. Neptune is the lawyer-led online prenup service: an independent attorney for each partner is included in a single flat fee of $5,000 from the start, not an add-on.
Flat fee of $5,000 per couple. No payment to get started.
Side by side
What each price actually includes
The headline price is not the whole story. What matters is whether an attorney is part of the process by default, or something you add on top.
| Feature | HelloPrenup | Neptune (lawyer-led online) |
|---|---|---|
| What the base price includes | A self-guided questionnaire and document builder. No attorney reviews your specific agreement at this tier. | A guided intake plus an independent attorney for each partner, drafting and reviewing your agreement. |
| Independent attorney for each partner | Optional add-on, priced per partner, on top of the base fee | Included in the flat fee. Each partner has an independent attorney: one drafts and one reviews. |
| Cost per couple | Base builder fee, plus a separate per-partner fee if you add attorney representation for both | $5,000 flat, both independent attorneys included |
| State availability | Available in most, but not all, states; a few require attorney representation by default | Attorney network available across the states Neptune serves |

What to look at closely
The gap is legal review, not the interface
A self-guided builder can be a fast, low-cost way to produce a document. The question worth asking is what happens after the document exists.
A builder can generate a document, not review it
At its base tier, HelloPrenup produces a document from your answers, but no attorney checks whether a specific clause fits your state’s rules or your situation unless you add representation separately. That review is what an attorney is for.
Independent counsel is what a challenge looks for
When a prenup is contested later, one of the first things examined is whether each partner had their own attorney. A self-guided document with no attorney involved leaves that question open; Neptune answers it by design, for every agreement.
Two separate fees can add up to more than one flat one
A base builder fee plus a per-partner attorney add-on is two line items, not one. Neptune’s $5,000 is the total for the couple, covering both independent attorneys, with nothing added later if you want a lawyer involved.
None of this means a self-guided builder can never work for a couple. It means the base price and the price with a lawyer involved are two different things, on either platform. Rules for what counts as valid disclosure and proper signing differ by state, and your attorney can review what applies where you live.

Common questions about Neptune and HelloPrenup
Does HelloPrenup include an attorney?
At its base price, HelloPrenup is a self-guided questionnaire and document builder: you and your partner answer questions and the platform assembles a document, with no attorney reviewing your specific agreement. Attorney involvement, including full independent representation for each partner, is available as a separate paid add-on. Neptune works the other way: an independent attorney for each partner is included from the start, in one flat fee.
How does HelloPrenup pricing compare to Neptune?
HelloPrenup charges a base fee for its self-guided builder, then a separate per-partner fee if you want attorney representation added on top. Neptune charges one flat fee of $5,000 per couple, and that fee already includes an independent attorney for each partner: one drafts the agreement, the other reviews it on behalf of the second partner. There is nothing to add later if you want a lawyer involved, because a lawyer is already part of the process.
Is a self-guided prenup builder legally valid?
It depends on what you add to it. A document generated from a questionnaire, with no attorney reviewing it, has not had the legal check that a licensed attorney provides. Adding attorney representation, whether through a builder’s paid add-on or a lawyer-led service like Neptune, is what brings that review into the process. Rules for what counts as a valid, enforceable agreement differ by state, and your attorney can review what applies where you live.
What is the real difference between HelloPrenup and Neptune?
HelloPrenup is built around a self-guided document builder first, with attorney involvement as something you add on. Neptune is built around two independent attorneys first, with a guided, AI-assisted intake that makes the process faster and less confusing before either attorney is on the clock. Both can get a couple to a signed prenup. The difference is whether legal review is the default or an extra step.
Which states does each service cover?
HelloPrenup is available in most states but not all, and a small number of states require attorney representation by default rather than the self-guided path. Neptune works with an attorney network across the states it serves, with each partner connected to their own independent attorney regardless of state. Your specific state’s requirements are worth confirming directly with either service, since availability can change.
