Prenups and postnups act as financial safety nets to protect your marriage from money-related conflicts and uncertainties. The difference between a prenup vs. postnup lies in timing—a prenup is created before you tie the knot, while a postnup comes into play after the wedding. Both agreements help couples outline how to handle assets, debt, and spousal support if the marriage ends. Once you learn the differences, you can create the one that’s right for you in our step-by-step document builder.
What Is a Prenup?
A prenup, short for prenuptial agreement, is a legal contract couples sign before marriage. It’s a way to plan how property, finances, and debts will be handled if the marriage ends in divorce.
Prenups can also outline alimony and protect assets like family businesses or inheritances. While some people think it’s unromantic, it’s really about setting clear expectations and protecting both partners’ interests. This way, you can focus on building a strong future together.
What Is a Postnup?
A postnup, or postnuptial agreement, is a legal contract couples create while married. It works like a prenup by outlining how assets, property, debts, and spousal support would be handled if the spouses divorce.
Postnups can also address changes in finances, like a big promotion or inheritance, and provide transparency during the marriage. It’s not about planning for a breakup—it’s about ensuring both partners feel secure and on the same page moving forward.
Prenup vs Postnup: Key Differences
Whether you’re preparing for marriage or adjusting to changes after getting married, a prenup or postnup can ease financial stress on your relationship. While they operate in similar manners, there are some key differences between a prenup vs postnup to familiarize yourself with.
Timing
The major difference between prenups and postnups is their timing. Couples sign prenups before the wedding bells toll, while they implement postnups after they are already married.
If you and your spouse never created a prenup before you were married, you will only ever need a postnup. However, even if you and your spouse signed a prenup, you may need to also create a postnup to address changes in financial circumstances.
Purpose
Prenups and postnups both outline how couples will manage their finances during their marriage and how they will divide assets and debts if the marriage ends.
While both documents can touch on the treatment of assets, businesses, and debts acquired before marriage, these details are typically more prevalent in prenups.
On the other hand, postnups tend to focus on changes in financial situations, such as a sudden acquisition of assets, the birth of a new child, or the management of newly acquired debt. They can also address missing or unclear matters in a prenup.
Who Signs
Any couple can sign a prenup or postnup to clarify financial expectations. However, some couples may be more likely to sign one document over the other.
Couples are more likely to sign prenups if one partner is a:
- wealthy individual who wants to protect their assets
- business owner who wants to keep their business separate
- person entering a second marriage who wants to reserve their assets for children from a previous relationship
Couples are more likely to sign prenups if they:
- didn’t sign a prenup but want to sort out their finances now
- want to manage one spouse’s acquisition of a large inheritance
- experience a change in income
- need to address financial disagreements that arose during the marriage
Circumstances When Signing
A prenup is often viewed as a natural part of pre-wedding planning. Couples enter prenup creation feeling ready to plan for their future together, so there may be less tension and a greater focus on teamwork.
Alternatively, a postnup can feel more reactive, as it often arises due to changes in marital dynamics or financial circumstances. However, couples can write a postnup amicably if they fully disclose their finances and focus on creating a fair agreement that benefits both parties.
All parties to a prenup or postnup must sign voluntarily without coercion or pressure.
Enforceability
Courts tend to investigate postnups more closely. They look for issues with fairness, as postnups may be created when the marriage is well along its way and one partner may have more leverage in the relationship.
In contrast, prenups typically face less scrutiny since couples draft them before getting married when both parties are on equal footing.
However, both agreements must have certain elements to be valid, such as voluntary entry and, in some jurisdictions, notary acknowledgment.
Complexity
When comparing a prenup vs. postnup, you can consider how they differ in complexity. Postnups may be more complex, as they can address changes that have occurred during the marriage, such as joint assets and debts. Prenups tend to be more straightforward, as they focus on what each person brings into the marriage.
Impact on Divorce
Prenups and postnups attempt to simplify divorce proceedings by describing the division of assets and finances. However, postnups can have a greater impact during divorce because they can address specific circumstances that arose after marriage.
| Factor | Prenups | Postnups |
|---|---|---|
| Timing | Before marriage | After marriage |
| Primary Purpose | Decides on treatment of assets acquired before marriage | Addresses changes in financial circumstances |
| Who Signs | Couples with significant assets before marriage | Couples navigating financial changes |
| Circumstances When Signing | Focus on teamwork | Can be seen as reactive |
| Enforceability | Usually easier to enforce | Usually more difficult to enforce |
| Complexity | Usually more straightforward | Usually more complex |
| Impact on Divorce | Can have an impact | Can have a more significant impact |
Common Misconceptions About Prenups and Postnups
Misunderstandings about prenups and postnups can lead to hesitation or cause couples to forgo them altogether. However, we’re here to clear up these myths to guide couples and help them make informed decisions.
1. They’re Only for the Wealthy
Many people think prenups and postnups are only for high-net-worth individuals or celebrity couples, but that’s far from true. Any couple, regardless of income or financial status, can benefit from these agreements.
Prenups and postnups can protect existing assets, such as a family inheritance, a business, or personal savings. They’re also useful for outlining how marital assets and debts will be divided in case of a divorce.
These agreements aren’t just about wealth—they can also provide financial clarity for couples with modest means. For example, suppose one partner enters the marriage with a lot of debt. A prenup or postnup can clarify the division of that debt to avoid future disputes. Ultimately, these documents help with financial planning and security, no matter the size of your bank account.
2. They Can Contain Any Terms
A common misconception is that prenups and postnups can include whatever terms a couple wants, but this isn’t true. These agreements have restrictions on what they can legally cover. For example, they cannot dictate child custody or child support arrangements. Courts will always decide these matters based on what’s best for the child.
Additionally, couples cannot include terms that are unfair, illegal, or unenforceable. In particular, they cannot add personal lifestyle clauses with extreme demands, such as that one spouse must maintain a certain weight. Such terms will likely invalidate the agreement.
Focus on financial and property-related matters in your prenup or postnup.
3. They’re Only for Before Marriage
Many assume these agreements are only for couples who haven’t yet married. While prenups are signed before marriage, postnups serve a similar purpose for partners who are married.
This misconception often stems from the fact that postnups are less well-known, and some people may not even realize they’re an option. Whether a couple didn’t think to create a prenup or their financial circumstances changed after getting married, a postnup offers a practical way to address financial matters and protect both partners.
4. They Can’t Be Amended
Some people believe that once they sign a prenup or postnup, it’s set in stone. However, this isn’t true. Couples can amend or update the agreement if they both agree to the changes. The revisions must also remain fair and lawful.
For example, couples might amend their agreement to reflect major life changes, such as starting a business, having children, or receiving an inheritance. Keeping the terms up-to-date ensures the agreement stays relevant and effective over time.
5. They Indicate a Lack of Trust
Prenups and postnups can have a poor reputation because people think their creation means a couple doesn’t trust each other. In reality, these agreements are more about fostering open communication and ensuring financial clarity.
Discussing financial matters, including assets, debts, and future goals, can strengthen a relationship. Instead of being signs of mistrust, prenups and postnups show a commitment to planning for the future, no matter what it holds.
To create an enforceable prenup or postnup, couples must provide full financial disclosure, which helps ensure the legitimacy and fairness of the agreement.
Which Is Right for Me and My Partner?
When deciding between a prenup vs postnup, it might seem like a postnup is just an afterthought—something you only get after you’re already married. But that’s not the case. A postnup can be as effective as a prenup in protecting both parties’ interests, even after the wedding. However, it’s important to remember that the best option depends on your unique circumstances.
Whether you’re creating a prenup before marriage or a postnup afterward, seeking legal counsel is key. A lawyer can ensure the agreement is fair, valid, and legally enforceable. While it might seem obvious which document you need based on your situation, consulting a legal professional ensures you make the right choice for your future together.
