Prenups and Postnups in Ohio: Planning for Your Financial Future Together
Congratulations, you just got engaged!
You are celebrating, sharing the news, and beginning to think about what life will look like after the wedding. Along with the excitement, this is also a natural time to talk about how you will handle finances, as a team.
Many couples assume prenuptial agreements are only for people with significant wealth or complicated financial situations. These agreements can apply to everyone in every situation. Even something as simple as a home purchased before marriage, a retirement account, or personal savings can make a prenup a helpful planning tool.
Prenuptial and postnuptial agreements are not about expecting a marriage to fail. They are about having clear, honest conversations early and making intentional decisions about your financial future together.
In this article, I will explain what prenups and postnups are under Ohio law, who may benefit from them, and why these agreements often provide clarity and peace of mind rather than conflict.
In this video, Attorney Claire O’Brien explains how prenuptial and postnuptial agreements work in Ohio and when couples might consider them.
What is a Prenuptial Agreement?
A prenuptial agreement, often called a prenup, is a written contract signed before marriage that outlines how certain financial matters will be handled if the marriage ends due to divorce or death. In Ohio, prenups commonly address:
How property will be classified as separate or marital
Responsibility for existing or future debts
Whether and how spousal support may be addressed
Protection of businesses, inheritances, or premarital property
Prenuptial agreements cannot determine child custody or child support. Under Ohio law, those decisions are always made by the court based on a child’s best interests at the time of separation.
What Makes a Prenup Enforceable in Ohio?
Ohio courts generally enforce a prenuptial agreement when three core requirements are met:
Full and fair financial disclosure by both parties
Voluntary agreement, free from pressure or coercion
Fair and reasonable terms that do not promote divorce or unfairly favor one spouse
Also, timing matters. If an agreement is signed too close to the wedding, a court may question whether one party felt pressured. From a practical standpoint, prenup discussions should start well in advance, so both parties have time to review the terms, ask questions, retain independent counsel, and make informed decisions.
You Do Not Need Significant Wealth to Benefit from a Prenup
A common misconception is that prenups only make sense for couples with substantial assets. In my view, that is not accurate.
If you own any assets at all, a prenup may be worth discussing. This can include:
A house or condo purchased before the marriage
Retirement accounts or investments
Savings accumulated prior to the relationship
A small business or side business
Family contributions or expected inheritances
Even when assets are modest, a prenup can clearly define what remains separate and what becomes marital. That clarity can help prevent confusion and conflict later and can protect both partners, not just the person with more assets.
Common Reasons Couples Consider Prenups
Prenups are not one size fits all, but they are especially helpful when:
One or both partners own a business
There is a difference in assets or income
One or both partners have children from a prior relationship
Either partner carries significant debt, such as student loans in certain cases*
A premarital home or family property needs protection
In these situations, a prenup can provide structure and predictability, which often reduces stress and uncertainty in the future.
*Student loans become martial debt typically when they are acquired during the marriage prior to separation, the spouse co-signed, and/or the education improved the couple’s overall standard of living, or if one partner gave up on earning capacity to support the other while obtaining the degree.
Already Married? Ohio Now Allows Postnuptial Agreements
As of March 23, 2023, Ohio permits postnuptial agreements, which are contracts entered into after marriage that serve a similar purpose as prenups. Postnups are often used when couples:
Did not sign a prenup but want clarity later
Experience a major financial change, such as an inheritance or business growth
Want to formalize financial expectations during the marriage
Like prenups, postnups must be in writing, voluntary, and supported by full financial disclosure. The one thing that they also cannot do is: determine child custody or child support. This is for the same reasons of the child’s best interest discussed above.
Addressing Common Concerns About Prenups and Postnups
A common concern and myth is that prenuptial and postnuptial agreements signal distrust or a lack of confidence in the relationship. That concern is understandable; however, in practice, I often see the opposite.
When handled thoughtfully, these agreements encourage honest conversations about finances, expectations, and long-term goals. Those conversations are an important part of building a strong foundation and having difficult conversations that some couples never even discuss. These conversations are most beneficial, especially when they happen early and intentionally, while both partners are focused on planning a life together.
Clear agreements can also reduce uncertainty. Rather than leaving important financial decisions to a court during an emotionally charged time, couples have the opportunity to define their own terms while they are aligned and communicating openly. For many couples, that clarity provides reassurance and allows them to move forward with greater confidence.
Why Legal Guidance Matters
Drafting a valid and enforceable prenup or postnup requires more than downloading a template. Ohio law places specific requirements on these agreements, and small mistakes can lead to disputes later.

Conclusion
