Online prenups have made it easier than ever for couples to protect themselves financially and start marriage with clarity and mutual trust. But while the process may seem simple, a few overlooked details can make your agreement weaker—or even unenforceable. Uncovering the most common mistakes when signing an online prenup helps you avoid unnecessary stress, delays, or legal complications later. And most importantly, it ensures that both partners feel respected and protected by the agreement they sign.
Common Online Prenup Mistakes to Avoid

1. Skipping Legal Review When Your State Requires It
Even the best online prenup platforms can’t override state laws. Some states require each partner to have their own lawyer review the agreement before it’s signed. Without that step, the prenup could later be challenged or invalidated in court.
If you’re unsure whether your state has this requirement, take a moment to check—or ask your online prenup service if they provide legal review options.
Even when it isn’t mandatory, a quick legal consultation can bring peace of mind and confirm that your agreement meets all local standards.
2. Forgetting Full Financial Disclosure
A prenup only works if both partners are honest about their finances. Forgetting—or choosing not—to disclose debts, assets, or income can render the contract unenforceable.
Transparency doesn’t weaken your position; it strengthens your prenup. It proves that both people entered the agreement willingly and with full understanding.
Most online platforms guide you step-by-step through the disclosure process, but it’s up to you to ensure everything is accurate and up to date.
3. Rushing Through the Agreement Without Discussion
A prenup signed in haste—especially right before the wedding—can be questioned later. Courts may see it as signed under pressure rather than mutual consent.
Take the time to sit down together and talk through what each clause means. You don’t need to agree on everything immediately, but both of you should feel comfortable and heard before signing.
Remember: a good prenup protects the relationship as much as it protects assets.
4. Not Checking for State-Specific Clauses
Each state has its own family law rules. Certain clauses—especially those limiting spousal support or discussing future child-related matters—may not be valid everywhere.
Before you sign, make sure your online prenup service customizes the agreement based on your state’s laws. A one-size-fits-all document could lead to unexpected problems later.
Good online platforms include these state-specific safeguards automatically, but double-checking them shows you’re taking the process seriously.

5. Neglecting to Store or Sign It Properly
It may sound obvious, but an unsigned prenup isn’t legally binding. The same goes for one that’s lost or inaccessible when needed.
Once both partners sign, keep digital and physical copies stored safely. Some states may also require notarization, which your online service can usually arrange.
These simple steps ensure your hard work doesn’t go to waste.

6. Ignoring Updates After Major Life Changes
A prenup isn’t a one-time document you sign and forget. Major life events—like having children, buying property, or starting a business—can change what’s fair or relevant in your agreement.
Revisiting your prenup after big milestones helps it grow with you. Think of it as part of ongoing communication and financial transparency in your relationship.
7. “Winning” Instead of Protecting Each Other
One of the biggest misconceptions about prenups is that they’re about control. In reality, the healthiest agreements are built on fairness.
The best prenups protect both people and help them start marriage with trust and clarity. When approached with care, this process can actually strengthen your partnership instead of creating distance.
Think of it as setting the tone for an honest, transparent marriage—not a competition.
You can avoid every one of these 7 mistakes with the right guidance and tools. A reliable online prenup service doesn’t just help you create a document — it walks you through each step, clarifies state-specific rules, and ensures both partners feel protected and informed.
That’s why it matters to choose a platform that simplifies the process and makes legal clarity accessible to both of you. Here’s one that could tick all the boxes for you, called HelloPrenup.
Is HelloPrenup Right for You? Key Benefits and Legal Considerations
Developed by a family law attorney and a software engineer (a former bride also), HelloPrenup is a modern, easy-to-use platform that helps couples create prenuptial agreements online—affordably, privately, and on their own timeline. With a flat fee of $599 per couple, it’s a much more accessible alternative to traditional lawyer-drafted prenups.
However, while HelloPrenup offers convenience, it’s still a tool for creating a serious legal document—one that can have long-term financial and emotional implications. So before diving in, it’s important to understand not just what HelloPrenup offers, but also what a prenup can and cannot legally include.
What HelloPrenup Does Well
1. Flat, Transparent Pricing: $599 per couple includes the full prenup-building process. No hidden fees, no hourly rates.
2. Optional Online Signing and Notarization: For $50 per couple, you can finalize your prenup entirely online.
3. Add Legal Help When You Need It:
- Attorney Q&A: $49 per fiancé.
- Full attorney review + signing + notarization: $699 per partner
4. Built for Collaboration: Each partner fills out their their own questionnaire, then both work together to align on shared terms.
5. Flexible and Discreet: Great for couples who want to start with a do-it-yourself approach and bring in legal support only if needed.
What to Consider Before Using HelloPrenup
1. State Laws Matter More Than You Might Think
Each U.S. state has its own laws about how prenups must be created and what makes them enforceable. Some (not many) states require independent legal counsel for each person or specific waiting periods before signing. Look up your state’s rules or have a local attorney quickly review your prenup before signing.
2. It’s Great for Simpler Financial Situations
HelloPrenup is ideal for couples without complicated finances—like multiple businesses, large estates, or blended family issues. If your finances are complex, consider drafting the basics, then have a lawyer finalize it.
3. Not All Clauses Are Enforceable – Here’s what cannot legally be included in a prenup, even with HelloPrenup:
- Provisions that encourage divorce: You can’t reward someone for divorcing, or include terms that seem to promote ending the marriage.
- Child support terms: Courts decide this based on current needs and state law. A prenup can’t pre-set support amounts or waive a child’s right to receive it.
- Child custody or visitation arrangements: You cannot decide custody in advance in a prenup; that’s up to the courts based on the child’s best interest at the time of separation.
- Illegal terms: Like any contract, a prenup must follow the law. You cannot include anything that would require a spouse to do something illegal. Focus your prenup on property division, debts, and financial rights—not parenting or court-controlled matters.
4. Extra Services Can Add Up
Although the base price is very affordable, the cost can rise if you need attorney help or add special features. You can decide upfront whether you want/need legal review on or off the platform, and budget accordingly. When couples need extra services, it’s still far cheaper than traditional routes for many.
5. Timing Can Affect Enforceability
Some states require a prenup to be signed a certain number of days before the wedding. Rushing the process could put your agreement at risk—or require a postnup instead. In this case, make sure not to wait until the last minute if possible. Start early so both partners have time to consider, negotiate, and seek legal advice if needed.
Last Tip
HelloPrenup is a thoughtful and cost-effective option for couples who want a prenup that protects both people without the intimidation of lawyers or hefty fees. But it’s not a substitute for understanding your legal rights or local laws so do your due diligence, stay realistic about your financial and legal situation, and seek attorney input when needed or appropriate.
Make sure to also ead their excellent FAQ as well to clear the doubts and get all the necessary information about the process. Your relationship deserves protection that’s not just affordable—but also enforceable, ethical, and built to last.
