How to Notarize a Prenuptial Agreement: A Practical Guide

Your prenuptial agreement is one of the most important documents you and your partner will sign together. Imagine investing time and emotion into creating an agreement, only to have its validity questioned when you need it most.

Thankfully, that risk is easy to avoid. Notarizing your prenup verifies your signatures and ensures the agreement holds up if ever challenged.

At Neptune, we simplify the entire process, from drafting and legal reviews to signing and notarization. The result? A valid and fair prenup, so you can focus on building your future together.

In this article, we’ll go through commonly asked questions like where to notarize papers and how to get a paper notarized online.

Why Notarization Matters for Prenuptial Agreements

Your prenup outlines how you and your partner will handle finances, property, and potential future changes in your relationship. But even the most carefully written prenup can face challenges if its authenticity is questioned.

This is where having notarized documentation makes all the difference.

A notary public acts as an impartial witness, verifying that:

• Both parties are who they claim to be.
• Both are signing voluntarily, without coercion or pressure.
• The signatures are legitimate and executed on a specific date.

This impartial verification strengthens the enforceability of the prenup. Some states even require notarization for prenuptial agreements, while others strongly recommend it to prevent disputes. 

By notarizing your prenup, you give the agreement an official seal that verifies proper execution.

How to Notarize a Prenuptial Agreement (Step by Step)

If you aren’t sure of where to notarize papers, here’s a step-by-step breakdown of how to get your prenup completed and notarized, made easier with Neptune’s support:

1. Draft your prenup

Before anything else, you need a clearly defined agreement. This isn’t just about dividing property in case of a separation. A prenup covers how you’ll manage finances during your marriage, handle debts, and even outline inheritance considerations.

Neptune helps you start the conversation with your partner and connects you with experienced attorneys who can draft an agreement tailored to your unique goals and state laws. Having a professional draft the document ensures it covers key issues and avoids vague or unenforceable terms.

2. Legal review for both partners

Each partner should have their own lawyer review the agreement. This is a critical fairness safeguard and, in some states, the law.

It’s also essential to know your state laws about attorneys and prenups. For example, California law strongly encourages both parties to have independent legal counsel and may require additional disclosures and waiting periods if one party waives that right. 

On the other hand, states like Texas do not mandate independent legal representation. However, it’s still recommended, as many prenups get thrown out due to claims of coercion, misunderstanding, or unfairness when one partner didn’t have their own attorney.

Having separate legal counsel helps ensure:

• Each partner fully understands their rights and obligations.
• The agreement is balanced and not one-sided.
• The prenup is less likely to be challenged later.

Neptune simplifies this by connecting you with vetted, expert family lawyers so both partners feel confident moving forward.

3. Signing the agreement

Once both parties agree to the terms, it’s time to sign your prenup. This is also the stage where many couples make mistakes, such as signing too close to the wedding or without proper witnesses.

To avoid issues, Neptune recommends:

• Signing well before the wedding date (ideally at least a month in advance).
• Ensuring both partners have their attorneys present (optional but helpful).

4. Where to notarize papers for a prenup

Now comes the critical final step of adding that legal seal of authenticity. If you’ve ever wondered where to notarize papers, here are your options:

• In-person notarization: You can visit banks, credit unions, law offices, or even shipping centers like UPS or FedEx. Many locations have walk-in availability, and fees are typically minimal (often $5–$25).
• Online notarization: If scheduling is an issue or you and your partner are in different locations, remote notarization is a convenient option. Companies like Proof allow you to notarize online using secure video technology. An online notary is able to verify your identity and witness your signature virtually. This is accepted in many states and often provides instant digital copies of your notarized prenup. 
• Through Neptune: We can provide you with vetted notaries options for both in-person and online options. 

What Happens If I Don’t Get My Prenup Notarized?

Failing to notarize your prenup might seem like a minor oversight, but it can have significant consequences:

• Questions about authenticity: If one partner disputes signing the document, proving its validity becomes much harder without notarization.
• Legal challenges: A judge may refuse to enforce the prenup or parts of it if it wasn’t properly executed according to state law.
• Delays and stress: Even if eventually enforceable, an unnotarized prenup can lead to costly legal disputes.

A simple notarization step ensures your prenup is valid and minimizes future risk.

Tips for Smooth Notarization

Here are some practical tips to make the prenup notarization process hassle-free:

• Don’t sign beforehand: The notary must witness the actual signing, so bring your unsigned prenup with you.
• Bring proper identification: Government-issued photo IDs (driver’s license, passport, etc.) are required.
• Plan ahead: Schedule the notarization appointment in advance to ensure both partners can attend at the same time.
• Consider online notarization: If travel or scheduling is difficult, remote notarization can save time and is legally accepted in many states.
• Keep multiple copies: After notarization, make both physical and digital copies and store them securely.
