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.

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.

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.

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. Where some services run intake through an AI chatbot and then hand you off to a separate attorney, First keeps the entire process on its platform from your first questions to signing.

First is also rated 5.0 on Google and 4.8 on Trustpilot, making it a compelling choice for couples comparing modern prenup options.
