First® vs Neptune
First and Neptune both give each partner an independent attorney for a flat fee. Couples choose First because it's the top rated online prenup platform, has a product experience loved by customers as seen in reviews, partners with attorneys who have 21 years of practice on average, and offers packages for simple to complex situations.
Key considerations
- Both pair each partner with an independent attorney for a flat fee, so neither leaves one partner unrepresented.
- First's Lawyer Review is $3,500 for two attorneys. Neptune's comparable two-attorney option is $5,000, so First is $1,500 less.
- First also offers a Self-Serve package at $649, and a custom-priced Bespoke package for complex situations.
- On a strict or shorter timeline, First may be a better choice: many couples finish in days to weeks depending on package. Neptune says its prenups typically take 3 to 4 weeks when both partners use Neptune attorneys, and can take up to a few months.
- First's attorneys average more than 21 years of practice.
- First is built to get you and your partner aligned. The guided questions exist to open the conversations that matter, and you work through them together on the First platform. Every package runs the same way, attorney review included, so you always know where things stand, what is needed, and what comes next.
- Clara, First's AI assistant, adds an always-available second set of answers on top of that, there the moment you want something explained.
- Neptune may suit you better if you would prefer to begin with an AI chatbot.

What couples say about First
"Seeing our answers side by side showed us exactly where we disagreed before the lawyers got involved. We worked out the hard conversations ourselves and came to counsel with a position, which saved real time and money."
"The lawyers we chose felt like they genuinely had our best interests in mind. They were also accessible outside of the platform via email and phone whenever we needed them."
"Moving through the different questions prompted many good discussions about financial management that we had not considered, both post- and during marriage."
My first (and last) prenup was a breeze with First. The platform itself was virtually flawless and we were impressed with our lawyers. My lawyer, Lars, was a superstar!
Sarah & Will
The process of generating our prenup [with First] was extremely simple. The lawyers answered all our questions and helped us ensure we had an agreement that worked for both of us.
Maite & Ryan
The self-service option allowed us to go through an expedited prenup process and have the meaningful discussions we wanted to about our marriage, just in time for the wedding itself. The process was easy (as easy as legalese can be!), quick, and affordable.

First vs Neptune: Pricing, Attorney Review & Coverage FAQ
Is First or Neptune cheaper?
For a prenup with an independent attorney for each partner, First is $1,500 less, and also offers a $649 Self-Serve option for couples who do not need full attorney representation (which Neptune does not have) with both packages including online notarization. Neptune’s comparable option is $5,000 for two attorneys, and Neptune’s own materials note the cost can run higher depending on complexity and market. Neptune also lists its drafting attorney alone at $3,000 to $3,500, close to what First charges for both partners’ attorneys.
It comes down to what you need, and either way, both cost far less than hiring two attorneys directly.
Does First include attorney review?
Yes. With First's Lawyer Review, each partner works with independent counsel licensed in your state who can advise, revise, and negotiate the language of their prenup. The $3,500 price includes the full drafting and review process, along with an attorney for each partner. The $649 Self-Serve plan is a guided do-it-yourself option without attorney review. All First packages include online notarization where state law permits.
How long does a First prenup take?
Many couples finish a First prenup in days, and the fastest took only 43 minutes (for Self-Serve). With Lawyer Review, days to a few weeks is common, depending on complexity and how quickly both partners and both attorneys review.
If you are on a strict or shorter timeline, First may be the better choice. Lawyer Review attorneys are trained on the First platform with reserved availability, and the platform guides you both through every step, from the first questions to signing.
Is First only for simple prenups, or can it handle complex finances?
First is built for every prenup, from the simplest to the most complex. Self-Serve, at $649, is drafted for your state from your answers and built for comprehensive protection, covering everything from RSUs to pet custody to family obligations. Lawyer Review, at $3,500, gives each partner their own independent attorney licensed in your state and handles the vast majority of complex cases, including spousal support provisions, immigration clauses and complex financial situations, for founders and business owners, blended families and cross-border couples. Bespoke is for the most complex cases, with strategic drafting and unique clauses for advanced financial provisions tailored for your situation.
How experienced are First’s attorneys?
First's attorneys average more than 21 years of practice. Many work regularly with complex finances, international assets and startup equity such as founder stock, options and RSUs. Several are certified family law mediators, some have served as judges pro tem, and others bring backgrounds in high-net-worth asset valuation, business interests, and trusts and estates. You choose your own attorney, and you can read every bio on our lawyers page. Neptune's attorneys have similar average years of practice.
Can I talk to someone before I choose a package?
Yes. A free 20-minute consultation is available before you buy, no matter which package you are considering, with no pressure and no commitment. Bespoke starts with a consultation. Neptune also offers free consultations.
Does each partner need their own attorney for a prenup?
Not always, but it is strongly recommended and can affect enforceability. For instance, under California Family Code § 1612, a spousal support waiver is unenforceable against a partner who did not have independent counsel. First's Lawyer Review and Bespoke packages, as well as Neptune's service, give each partner their own attorney, the gold standard for enforceability.
What states does First cover?
First offers prenuptial agreements in 46 states and Washington, D.C., which includes Alabama, Alaska, Arizona, Arkansas, California, Colorado, Connecticut, Delaware, District of Columbia, Florida, Georgia, Hawaii, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Maine, Maryland, Massachusetts, Michigan, Mississippi, Missouri, Montana, Nebraska, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, Vermont, Virginia, Washington, Wisconsin, and Wyoming. Coverage is expanding, so sign in and go through the eligibility check before you start.
Is First legit?
Yes. First® is the highest-rated online prenup service we compare, at 4.9 on Trustpilot and 5.0 on Google, and what couples praise most is the experience: First is built to feel like the apps you already use, not a law office. You and your partner build your prenup together on one platform, at your own pace, and your agreement is drafted around your state’s requirements. Free online notarization comes with every package, wherever your state accepts remote online notarization.
First also takes the hardest part off your plate. Hiring two attorneys on your own typically runs $3,000 to $10,000 or more per couple, plus the time it takes to find and vet them. With First, you choose the level of support you need at a flat price: a self-guided prenup with Self-Serve for $649, an independent attorney for each of you through Lawyer Review for $3,500 where it’s offered, or Bespoke support for the most complex financial situations. First’s attorneys average more than 21 years of practice, and you can read couples’ first-hand experiences in our reviews.

Is First a good Neptune alternative?
Yes. First gives each partner an independent attorney for $3,500, $1,500 less than Neptune's $5,000. It is a strong Neptune alternative for couples who want a high-quality, transparent online prenup process that includes independent attorneys for both partners while saving $1,500 or more.
First is designed around collaboration, so both partners work through the agreement together and feel confident in what they're signing. The platform guides you through every step, includes free online notarization where legally accepted, and gives both partners access to independent attorneys whenever you want them, with no need to go find and retain counsel on your own. First keeps the entire process on its platform, from your first questions through signing, with the attorney review stages running in the same place.
First is also rated 5.0 on Google and 4.9 on Trustpilot, making it a compelling choice for couples comparing modern prenup options.
