How Neptune Works

Plan for Your Future, Together

We’re not a prenup generator. Neptune offers a smarter, guided experience for both partners to thoughtfully plan for what’s next.
Step 1
Align on What Matters

Talk through values, goals, and assets -- together. Neptune guides the conversation before the lawyers do (saving you $).

Step 2
Meet Vetted Lawyers

Connect with experienced lawyers for both partners. No retainers, just transparent flat-fee pricing and free consultations.

Step 3
Craft & Finalize your Prenup

Your attorneys will create the prenup; Neptune will facilitate signatures and notarization.

Built for Transparency

Clarity, control and flat-fee pricing

Frustrated by retainers and hourly billing? So were we. Unclear if your lawyer has done this before? We’ve been there.

Prenups are complex.
Getting answers shouldn’t be.
