Not all prenups are created equal.
A prenup is only as strong as the attorneys behind it, but finding one you actually trust usually means endless vetting, back-and-forth scheduling, and awkward office visits. No wonder so many couples settle for less, or avoid the process altogether.

Frequently asked questions
What is Neptune?
Neptune helps couples navigate the financial and legal side of building a life together, starting with prenups. Unlike DIY templates or one-size-fits-all generators, we guide you and your partner through alignment conversations first, then connect you with vetted family law attorneys to draft an agreement.
Is the initial consultation free?
Yes. Each partner gets a free 20–30 minute call with an attorney to share concerns and ask questions. After that, it’s your call whether to move forward.
What makes a prenup legally enforceable in California?
California courts generally look for full financial disclosure from both partners, terms that are fair to both sides, and proper execution. Neptune connects you with experienced California family law attorneys who can review the details for your situation.
Does California require separate lawyers for a prenup?
California generally requires each partner to have independent counsel for terms like spousal support, and independent lawyers are strongly recommended otherwise. Without independent counsel, your attorney can review whether an agreement is more vulnerable to challenge.
How much does a prenup cost?
A typical prenup runs $5,000–$20,000+ when each partner hires their own hourly attorney. With Neptune, it’s $5,000 flat for both, no surprise bills, and attorneys with 20+ years of family law experience.
Why is Neptune more affordable?
By handling the upfront intake and organization, our attorneys can focus on the legal work, not admin. That efficiency, plus flat rates negotiated with our vetted lawyers, means better guidance at a predictable price.
How long does a prenup take?
Most couples complete the process in 3 to 4 weeks. California law includes a 7-day waiting period before signing, so we recommend starting 2 to 3 months before your wedding date for comfortable time to draft, disclose finances, and review with independent counsel.
What should we expect from our lawyers?
Neptune works with experienced family lawyers who understand both litigation and collaborative practice in California. Your attorney will take the time to understand your relationship, finances, and what matters to each of you. Expect empathetic and clear guidance, and an agreement you both feel good about.
Do you serve my area?
Yes. We work with couples anywhere in California through virtual consultations, so you get the same attorneys and process whether you’re in LA, the Bay Area, or anywhere in between.
