Real love talks about money

Today’s couples start marriage with more at stake -- and more intention.

Sol Lee
Co-Founder & CEO

Our Founder’s Lonely Prenup Journey

Getting a prenup was a lonely experience. None of my  friends or family had gone through the process. And when I brought it up with my partner, we argued - not because we disagreed, but because we didn’t know where to start or how to talk about it.

But working through that process turned out to be one of the most valuable things we’ve done as a couple. It forced us to talk -- really talk -- about how we see money, fairness, and the future we are building together. What started as a legal formality became a moment of alignment and radical transparency.

This is why we built Neptune.

We want to empower couples with the guidance to navigate life’s most personal financial decisions together. Prenups are just the beginning. Across marriage, careers, kids, and caregiving -- money will show up in every chapter of your relationship. So let’s talk about it.

Frequently asked questions

General

What is Neptune and how can it help me with my prenup?
Neptune is a modern platform designed to guide couples through the prenuptial agreement process in California. It helps you talk through key financial and relationship priorities, then connects you with experienced California family law attorneys to draft and review your prenup — all starting for free.
Is Neptune's chat service really free?
Yes, Neptune is completely free to use. We believe every couple should have access to the guidance they need to navigate their California prenuptial agreement with clarity and confidence.
Is my conversation with Neptune private?
Absolutely. Everything you share in the form is private and confidential. We follow strict privacy and data protection standards to ensure your information is secure — from your initial answers to your final California prenuptial agreement.
Is there anything else Neptune can help me with besides prenups?
Neptune is currently focused on prenups, but we are always expanding our services. In the future, Neptune may be able to assist with other legal decisions for couples like marriage, immigration and trust & estate planning.
What if I'm not sure if I need a prenup?
Neptune can help you explore your financial situation and goals as a couple. The conversation will help you decide if a prenup is right for you.

Prenups

Can you change a prenup?
Yes, a prenuptial agreement in California can be amended after it's signed — as long as both partners agree. This is usually done through a postnuptial agreement or by revising the original prenup with the help of a licensed attorney. Neptune connects you with trusted California family law attorneys who can guide you through the process.
Can you sign a prenup after marriage?
While a prenuptial agreement in California is signed before marriage, couples can choose a postnuptial agreement after marriage. It serves a similar purpose and can be tailored to your needs. Neptune connects you with family law attorneys who can guide you through your options.
How long does a prenup take?
A prenuptial agreement in California can take weeks or even months — but with Neptune, we move fast. We streamline the process and connect you quickly with top family law attorneys so you can finalize your prenup efficiently and without delays.
Do prenups hold up in court?
When drafted and executed properly, prenups are legally enforceable. A court will typically uphold a prenup as long as it is fair, both parties entered into it voluntarily, and it complies with state laws. Neptune prenups are built from the ground up, not by a template.
What are the pros and cons of a prenup?
A prenup can offer peace of mind and financial protection, but it can also come with difficult conversations or the need for updates down the road. Whether you’re sure about moving forward or still considering your options, Neptune can connect you with trusted, experienced family law attorneys to help you navigate the process.

How much does a prenup cost?
Traditional prenups in California can cost thousands. Neptune connects you with lawyers who offer clear, flat-rate pricing — no hidden fees, ever.
How does Neptune ensure transparency with attorney prices?
We prioritize transparency in every aspect of our service. When users access local family law attorneys through Neptune, they can view transparent pricing for prenuptial agreements upfront. This ensures clarity and helps users make informed decisions that align with their budget.

Lawyers

Does Neptune replace a lawyer?
No. Neptune provides guidance and facilitates communication, but we do not offer legal advice. Our partnered attorneys will draft and review your prenup to ensure it's legally sound and reflects your specific needs according to your state laws.
How do I find a lawyer through Neptune?
Neptune streamlines the lawyer discovery process. We carefully vet and curate a selection of top family law attorneys who specialize in prenuptial agreements. We match you with a list of family law attorneys in your state that best suits your needs and budget.
Can I use Neptune to write a prenup without a lawyer?
While Neptune guides you through important conversations and helps you align on your goals, we always recommend working with a qualified attorney to draft and finalize your prenup. This ensures it meets legal requirements and protects both partners.
How are Neptune's lawyers vetted and selected?
At Neptune, we carefully vet our lawyers for their expertise in family law, so you don’t have to. They are chosen based on their reputation, experience, and commitment to transparent pricing, ensuring you receive the best possible service.
