What Could Make a Prenuptial Agreement Invalid?

Prenuptial agreements (often called “prenups”) are no longer a rare topic in modern marriages. More couples today are choosing to draft prenuptial agreements to protect their personal or family assets, clarify financial responsibilities, and prepare for unexpected scenarios. While prenups can be an effective tool to ensure financial security and transparency, not all agreements stand the test of time—or the courtroom.

At The Women’s Divorce & Family Law Group, we’ve seen too many people get taken advantage of during their divorces due to unfair prenuptial agreements. If you’re navigating a divorce or questioning the fairness of a prenuptial agreement, understanding what might render it invalid is crucial. Below, we’ll review the common reasons a prenup may be invalidated and the steps you can take to challenge one if necessary.

What Could Make a Prenup Invalid?

In Illinois, prenuptial agreements are recognized as legally binding contracts enforceable in court. However, for a prenup to hold up legally, it must meet specific requirements. There are several factors that can render a prenuptial agreement invalid:

1. Lack of Voluntariness

A prenuptial agreement is invalid if one party was coerced or pressured into signing. Examples of duress can include:

• Presenting the agreement just days before the wedding and applying emotional pressure.
• Threatening to call off the wedding unless the other party signs.
• Using intimidation or manipulation to influence the decision.

2. Failure to Disclose Finances

If one party fails to disclose their full financial picture—be it assets, debts, or income—the other party cannot make an informed decision. Courts are highly critical of any form of dishonesty or omission in financial disclosures.

3. Unfair or Unconscionable Terms

A prenup that is extremely one-sided may be deemed “unconscionable.” For example, if one spouse leaves the marriage with almost all the assets while the other is left with little to no financial security, a court can view the agreement as unjust and invalidate it.

4. Improper Execution

Even minor errors in the drafting or signing process can lead to issues. Common mistakes include:

• Lack of proper legal counsel for one or both parties.
• Failing to meet state-specific legal requirements, such as notarization or witness signatures.

5. Invalid Provisions

Prenups cannot include illegal or unenforceable clauses, such as those dictating child custody or child support. Courts retain the authority to determine what is in the best interest of the child, despite what a prenuptial agreement might state.

6. Time and Circumstance Changes

While not common, some courts may consider whether the conditions of the agreement are still fair given time or circumstance changes. For instance, if significant financial disparities now exist due to unforeseen events, the court might review the prenup’s validity.

Understanding these pitfalls is essential whether you’re drafting a new agreement or questioning the validity of an existing one.

How to Challenge a Prenup

If you believe your prenuptial agreement is invalid, follow these steps to challenge it effectively:

• Consult an Experienced Family Law Attorney

The first and most important step is to contact a skilled family law attorney who is experienced in divorce and prenuptial agreements. They will review your case, analyze the agreement, and identify potential issues.

• Gather Evidence

Document any factors that could demonstrate the prenup’s invalidity. This may include communications showing coercion, proof of omitted assets, or instances where you were denied legal counsel.

• Focus on Unconscionability

Highlight clauses that are one-sided or inherently unfair. Courts are more inclined to take action when presented with a clear case of unconscionability.

• Provide Courtroom Testimony

If the case proceeds to court, be prepared to testify about the circumstances under which the prenup was signed. Solid, credible accounts of coercion, misrepresentation, or unfairness will strengthen your case.

Challenging a prenuptial agreement can be a complicated and sensitive process. Securing reliable legal representation from the outset is essential to navigating this terrain.
