If you believe your prenuptial agreement is unfair or was improperly created, you may be wondering whether it can be “nullified.”
The answer depends on the facts of your case.
Simply regretting the agreement or believing you made a bad financial decision is usually not enough. However, there are situations where a Utah court may determine that a prenuptial agreement should not be enforced.
A Salt Lake City family lawyer can answer any questions you have.
What Does It Mean to “Nullify” a Prenuptial Agreement?
People often use the word “nullify” to mean making a prenuptial agreement null and void. Legally, the issue is usually whether the court will enforce the agreement.
In some situations, the court may determine that:
- The entire agreement is enforceable;
- Only certain provisions are enforceable; or
- All or part of the agreement should not be enforced.
Whether that happens depends on Utah law and the specific facts surrounding the agreement.

Are Prenuptial Agreements Enforceable in Utah?
Generally, yes.
Utah has adopted the Uniform Premarital Agreement Act (UPAA), which establishes the legal framework for prenuptial agreements in the state. A properly prepared agreement that complies with the law will often be enforced. However, the UPAA also identifies circumstances in which enforcement may be challenged.
Because every contract is different, a court evaluates the contract’s language and the circumstances under which it was signed.

When Can a Prenuptial Agreement Be Challenged?
A prenuptial agreement is not automatically invalid simply because one spouse later believes it was unfair.
Instead, the court may consider issues such as whether:
- The agreement was signed voluntarily
- One party was pressured or coerced into signing
- There was fair disclosure of assets and debts
- The agreement satisfies the legal requirements under Utah law
Each challenge depends on the evidence presented to the court.
Can You Claim You Were Forced to Sign?
Possibly, but simply feeling emotional before a wedding is usually not enough.
For example, if someone presents a complex prenuptial agreement the night before the wedding and threatens to cancel the ceremony unless it is signed immediately, that may raise questions about whether the agreement was truly voluntary.
On the other hand, an agreement negotiated weeks or months before the wedding, with ample opportunity to review it, is generally much less vulnerable to that type of challenge.
Every situation is fact-specific.
Does Hiding Assets Matter?
Yes.
One purpose of a prenuptial agreement is to allow both future spouses to make informed financial decisions.
If one party intentionally conceals significant assets, income, or debts before the agreement is signed, that may affect whether the agreement, or portions of it, should be enforced. Complete financial disclosure is one reason properly prepared prenuptial agreements tend to withstand later challenges.
Can an Unfair Agreement Be Set Aside?
People often assume that if a prenup seems unfair years later, a judge will throw it out.
That is not necessarily how the law works.
The fact that one spouse ultimately receives more property than the other does not automatically make a prenuptial agreement invalid.
Courts generally distinguish between an agreement that later produces an unfavorable result and one that was legally defective when it was created.
What Will Not Usually Nullify a Prenuptial Agreement?
Many internet articles suggest that certain events automatically cancel a prenup. In most cases, they do not.
Examples include:
- Adultery
- Addiction or relapse
- Arguments during the marriage
- Deciding the agreement was a mistake
- Remaining married for many years
Those events may affect other aspects of a divorce, but they do not automatically invalidate a prenuptial agreement.
The legal question is whether the agreement itself is enforceable under Utah law.
Can a Couple Cancel Their Prenup?
Yes.
Spouses can generally agree to revoke or modify a prenuptial agreement after they are married.
However, this typically requires a new written agreement that satisfies the applicable legal requirements.
One spouse cannot simply decide the prenup no longer applies.
Should You Stop Following the Agreement?
No.
Until a court determines otherwise, or both spouses legally modify the agreement, you should assume the prenuptial agreement remains in effect.
Ignoring its terms without legal advice may complicate your divorce and create additional disputes.
Why You Should Have the Agreement Reviewed
Here are a few reasons you should have a lawyer review your prenuptial agreement:
- Every prenuptial agreement is different
- The wording matters
- The timing matters
- The financial disclosures matter
- Small details can significantly affect whether a challenge is likely to succeed
Rather than relying on general information online, it is important to have an experienced Utah family law attorney review both the agreement and the circumstances surrounding its execution.
An attorney can identify potential issues that may not be obvious and explain how Utah law applies to your specific situation.
