Can a Prenuptial Agreement Be Voided?

By Beverly Bird

When your marriage is disintegrating and you suspect divorce is looming on the horizon, it can be a big comfort to know that you and your spouse had the foresight to sign a prenuptial agreement. Unfortunately, prenups don't hold up in divorce court 100 percent of the time. Judges can and have thrown them out when certain aspects are in flagrant violation of the law or public policy. If you changed your mind about your agreement after you signed it, you might have voided it as well.

Timing and Duress

Laws regarding prenuptial agreements vary by state. Many jurisdictions have adopted the Uniform Premarital Agreement Act, but states often tweak the terms of the UPAA when integrating them into their own statutes. Many of the highlights are consistent, however. For example, the timing of a prenuptial agreement is often critical. A New York court has ruled that signing a prenup four days before the wedding is insufficient time, particularly if there are other problems with the agreement. California requires that seven days must pass between the signing and taking vows. Courts tend to be on the alert for signs that a spouse executed the agreement under duress, such as when the wedding is paid for and the whole thing might be called off if she doesn't cooperate. Depending on where you live, if you signed your agreement at the eleventh hour and your spouse decides to contest it in divorce court, you may have a problem.


Another important factor contributing to the validity of a prenup is whether spouses had separate legal representation. California's version of the UPAA requires that spouses hire independent counsel to review the agreement and to advise them regarding their rights. You can get around this rule in some states, however, if your spouse signed a waiver stating that she was advised to seek legal representation but decided against doing so.

False Promises

In a landmark 2013 case, a New York appeals court voided a prenuptial agreement because the wealthier spouse lied, promising he would tear it up if certain conditions were met after the wedding. He didn't tear it up, but instead presented it to a divorce court. The court ruled that his spouse was "fraudulently induced" into signing it. Most states require full disclosure by both spouses in an effort to avoid issues of fraud. This ensures that both spouses know the extent of their partner's wealth before they sign an agreement to waive their rights to a share. If you lied about your assets and only disclosed half of them, the court is likely to void your agreement if you divorce. If you overlooked a small asset, however, such an omission probably will not affect your divorce proceedings.

Unconscionable Terms

The terms of your prenup must not be unconscionable, particularly if your state does not impose a waiting period between the time of the signing and your wedding, or if your spouse waived her right to separate legal counsel – that is, if a lawyer would have told her that what she was agreeing to was blatantly unfair. An unconscionable premarital contract is one that is so grossly one-sided, the judge would have to wonder about the circumstances under which your spouse signed it. For example, if your agreement states that everything you earned or acquired before your wedding is yours, that all property acquired during your marriage is yours, and that your spouse has no right to either spousal support or an equitable division of property, the court will probably void your prenup because its terms are unconscionable.

Unforeseen Circumstances

Unforeseen circumstances can invalidate your prenuptial agreement. For example, you and your spouse may have been equally well off at the time you signed it, but she suffered an incapacitating accident after your wedding. She might have waived her right to alimony in the prenup, but now she's no longer able to support herself. Some courts will overturn a prenup if she would be eligible for public assistance because she was not receiving financial support or property from you. The state doesn't want to support your spouse if you have ample resources to help her out.

Voiding the Contract Yourself

You may also have voided your prenup on your own by writing and signing a superseding agreement. The secondary document might state that you're throwing the first one out entirely, or it may only amend certain provisions. In either case, this is the document the court will use if you end up divorcing.

Discovered Marital Property After Divorce

Finding out after your divorce that your spouse hid assets from you can result in a decidedly sinking feeling, especially if those assets are of significant value. But your ex should experience the distress, not you. You have options to claim your rightful share while your ex-spouse faces potential punitive damages. Depending on where you live, it doesn’t always matter that your divorce is behind you.

Unconscionable Divorce Agreement

Most states prefer that spouses negotiate a marital settlement agreement on their own when they divorce, rather than ask the court to decide issues at trial. These agreements must usually be submitted to a judge for approval before they are incorporated into decrees or judgments. A judge won't approve your agreement if it's unconscionable. If you don't file for divorce, but just remain separated under your agreement's terms, it may not be enforceable either.

What Is a Binding Contract for Divorce?

Whenever you sign something in the process of your divorce, it’s usually binding. Whether it is a contract depends on the nature of the document. A divorce complaint or petition is binding because you’re swearing to the facts it contains, but it's not a contract. Contracts obligate the signers to take or abstain from taking certain actions.
