First® vs Neptune
First and Neptune both give each partner an independent attorney for a flat fee. For most couples the decision comes down to price, the range of options, and track record. Here's why couples choose First as the preferred alternative.
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.
- 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.

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!

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
Verified customer
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?
First uses flat, all-in pricing: $649 for Self-Serve and $3,500 for Lawyer Review, which includes independent attorney review for both partners. Online notarization is included. 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.
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). 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. First's Lawyer Review plan includes independent attorney review for both partners, with each person represented by their own counsel, in one flat $3,500 fee. The $649 Self-Serve plan is a guided do-it-yourself option without attorney review. Both include online notarization where state law permits.
How long does a First prenup take?
Most couples complete a First prenup in days, rather than the several weeks a traditional attorney-led process can take. Timing depends on how quickly both partners finish the guided questionnaire and review the agreement.
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 a good Neptune alternative?
Yes. First 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.
