Prenuptial Agreements: What They Can and Can’t Do

Prenuptial agreements, often called “prenups,” are legal contracts signed by a couple before marriage. While prenups are sometimes seen as unromantic, they can actually help couples start their marriage with clear expectations and fewer misunderstandings. Knowing what a prenuptial agreement can and cannot do is key to deciding whether one is right for you.

What Is a Prenuptial Agreement?

A prenuptial agreement is a written contract that explains how certain issues will be handled if the marriage ends due to divorce or death. It is signed before the wedding and becomes effective once the couple is legally married.

Prenups are commonly used by couples who own property or businesses, have children from a previous relationship, expect a large inheritance, or have significantly different income or debt levels. While prenups are often associated with wealthy individuals, they can benefit many couples, regardless of income.

What a Prenuptial Agreement Can Do

Prenuptial agreements are flexible, but they must follow state laws. Common issues a prenup can legally address include property division, debt responsibility, business interests, spousal support, and inheritance protection.

A prenup can clearly state which assets belong to each spouse and how property will be divided if the marriage ends. It can outline who is responsible for certain debts, protect business interests from being divided or disrupted in a divorce, address whether spousal support will be paid, and help ensure children from previous relationships receive certain assets.

What a Prenuptial Agreement Cannot Do

While prenups can cover many financial topics, they cannot decide future child custody or child support arrangements. Courts always make these decisions based on the child’s best interests at the time of separation or divorce.

Agreements that are extremely one-sided or encourage illegal behavior are unlikely to be enforced. Prenups should not include personal rules about chores, appearance, or behavior. If one spouse was pressured, threatened, or rushed into signing the agreement, a court may invalidate it.

Requirements for a Valid Prenuptial Agreement

For a prenup to be enforceable, certain legal standards must be met, including full and honest financial disclosure by both parties, voluntary agreement without coercion, fair and reasonable terms, and proper execution according to state law. Both parties should also have enough time to review the agreement before the wedding.

Do Both Spouses Need Their Own Lawyer?

While it may not always be required, having separate legal counsel is strongly recommended. Independent attorneys help ensure that both spouses understand the agreement and that no one is being taken advantage of. Working with an experienced family law attorney, such as those at Chicklo Law Group, can help make sure a prenuptial agreement is properly drafted and more likely to hold up in court.

Are Prenuptial Agreements Only for Divorce?

No. Prenups can also play an important role in estate planning. They can clarify what happens to assets if one spouse passes away and reduce confusion or conflict among surviving family members. In many cases, a well-written prenup actually protects the marriage by reducing financial uncertainty and preventing future disputes.

Final Thoughts

Prenuptial agreements are not about planning for failure—they are about planning for clarity. By clearly outlining financial expectations, couples can avoid costly and stressful legal battles later on. However, prenups are legal documents with long-term consequences. Understanding what they can and cannot do is essential before signing.
