Your Complete 2025 Guide to Prenuptial Agreements

Prenuptial agreements have evolved far beyond being tools for the ultra-wealthy. Today, they’re recognized as one of the smartest forms of financial planning a couple can make. In fact, 50% of U.S. adults now support prenups, up from 42% just last year. Among younger couples, they’re even more common: 47% of engaged or married millennials and 41% of Gen Z couples already have one in place.

This shift reflects a fundamental change in how couples approach marriage. Instead of viewing prenups as pessimistic, modern couples see them as blueprints for financial partnership. That’s exactly what Neptune helps couples build: clear, fair agreements that strengthen relationships instead of straining them. With emotionally intelligent AI, vetted legal experts, and transparent flat-fee pricing, Neptune makes the prenup process as thoughtful as it is efficient.

What is a Prenuptial Agreement?

A prenuptial agreement is a financial roadmap created before marriage. While many people think of it only in the context of divorce, the reality is broader: prenups set expectations for how a couple will manage money, assets, and debts during marriage as well as if the relationship ends.

Key areas typically covered include:

• Property ownership (current and future)
• Living expenses and debt responsibilities
• Inheritance rights and estate planning
• Business interests and investments

The best prenups are opportunities for open communication and alignment on money values. When done thoughtfully, they help partners approach marriage with clarity, security, and a stronger foundation for the future. Neptune’s platform is designed to make these conversations easier, guided, and productive.

When to Consider a Prenup

A prenup can be valuable for nearly any couple, but it’s especially useful if:

• You own significant assets such as real estate, investments, or business interests
• You have children from a prior relationship and want to protect inheritance rights
• One partner carries substantial debt, like student loans
• You’re starting a business together (or separately)
• You want to define financial terms yourselves instead of relying on state laws
• You’re marrying later in life with established assets and retirement savings

Understanding Prenup Costs and Online Options

Traditionally, prenups required two lawyers, many billable hours, and several months, often costing tens of thousands of dollars. Today, online prenup services offer more accessible and affordable alternatives.

Flat-rate services like Neptune provide:

Making Your Prenup Valid and Enforceable

For a prenup to stand up in court, it must meet five key criteria:

1. Be in writing
2. Be made voluntarily (no coercion or last-minute pressure)
3. Include full financial disclosure from both partners
4. Contain terms that are fair, not unconscionable
5. Be properly executed and notarized

Neptune’s process ensures these requirements are met, so couples can feel confident their agreement is both fair and enforceable.
