A prenuptial agreement, often called a “prenup,” is a legal contract entered into by a couple before marriage. While some people assume prenups are only for the wealthy, they can benefit anyone who wants clarity and protection when it comes to finances. However, not everything can—or should—be included in a prenup. Understanding the limits is key to creating an agreement that is both enforceable and effective.

What Can Be Included in a Prenup
Prenuptial agreements are primarily designed to address financial matters. One of the most common uses is to define how assets and debts will be divided in the event of divorce. This can include real estate, bank accounts, investments, and even future earnings.
Couples can also outline how they want to handle spousal support (alimony). For example, a prenup may set limits on the amount or duration of alimony, or waive it altogether, depending on state law.
Another important area is debt protection. A prenup can specify that one spouse is not responsible for the other’s pre-existing debts, such as student loans or credit card balances. This is particularly helpful when one partner enters the marriage with significant financial obligations.
Business ownership is another common inclusion. If one spouse owns a business, the prenup can ensure that the business remains separate property and outline how its value will be treated in a divorce.
What Cannot Be Included in a Prenup
While prenups are flexible, they do have clear legal boundaries. One major limitation is that they cannot determine child custody or child support. Courts always decide these issues based on the best interests of the child at the time of the case, regardless of what a prenup says.
Prenups also cannot include illegal or highly unfair provisions. If an agreement is deemed unconscionable—meaning it is extremely one-sided—it may not be enforced by a court. Both parties must enter the agreement voluntarily and with full financial disclosure.
Additionally, personal lifestyle clauses can be problematic. While some couples attempt to include terms about household responsibilities or personal behavior, these provisions are generally not enforceable in court.
Why Proper Drafting Matters
A well-crafted prenuptial agreement can provide peace of mind and prevent costly disputes down the road. However, poorly written agreements can be challenged or invalidated. Working with an experienced family law attorney ensures that your prenup complies with state laws and accurately reflects your intentions.
Ultimately, a prenup is not about expecting a marriage to fail—it’s about planning responsibly and protecting both parties. With the right approach, it can serve as a strong foundation for a transparent and secure financial future.
