Frequently asked questions
What is Neptune?
Neptune is the lawyer-led online prenup service. Both partners get their own lawyer for a flat fee. Neptune helps couples navigate the financial and legal side of building a life together — starting with prenups. Instead of DIY templates or automated generators, we guide you and your partner through values alignment first, then connect you with vetted family law attorneys to draft a tailored agreement.
Is the initial consultation free?
Yes. Each partner gets a free 20–30 minute conversation with their attorney to learn about their background and share your situation. After that, you decide whether to move forward.
How much does a prenup cost?
A typical prenup costs $5,000–$20,000+ when you hire two hourly attorneys. With Neptune, the total cost is $5,000 for both lawyers — flat rate, no surprise bills. Our attorneys average 20+ years of family law experience.
Why is Neptune more affordable?
We handle the upfront intake, alignment, and organization so your attorneys can focus on the legal work — not admin and back-and-forth. That efficiency, combined with flat rates we negotiate with our vetted lawyers, means better guidance at a predictable price.
How long does a prenup take?
Typically a few weeks to a few months, depending on the complexity of your terms and how quickly you and your partner align. Our process is designed to keep things moving with guidance from your attorneys at each step.
What should we expect from the lawyers?
Your attorney will take the time to understand your relationship, finances, and what matters to each of you. Expect clear guidance on your options and how the process works from start to signature. Neptune works with experienced family lawyers who understand both litigation and collaborative practice. They know how courts treat prenups and they understand the emotional weight of these conversations. That means less friction between you and your partner, and an agreement you both feel good signing.
