Prenuptial and Postnuptial Agreements in Nebraska

A valid prenuptial or postnuptial agreement can override Nebraska's default equitable distribution rules entirely — protecting separate property, limiting alimony exposure, and defining how assets and debts will be divided if the marriage ends. But not every agreement holds up in court. Nebraska judges scrutinize these agreements carefully and will refuse to enforce them if they fail specific legal standards.

What a Prenuptial Agreement Can Do

A prenuptial agreement (signed before the marriage) allows both parties to define their own property division rules instead of relying on the court's equitable distribution framework under § 42-365. Common provisions include:

• Protecting premarital assets: Designating specific assets as separate property that will not be subject to division
• Protecting business interests: Ensuring a business started before the marriage remains with the owning spouse
• Limiting or waiving alimony: Agreeing in advance that neither spouse will seek spousal support, or capping the amount and duration
• Defining how future assets are classified: Specifying that certain categories of income or investment growth remain separate
• Protecting against the other spouse's debts: Ensuring premarital debts stay with the debtor spouse

A prenuptial agreement cannot waive child support or custody rights — courts retain full authority over matters affecting children regardless of what the parents agreed to before the marriage.

Postnuptial Agreements

A postnuptial agreement serves the same function as a prenup but is signed during the marriage. Nebraska courts enforce postnuptial agreements under the same general standards, though they face slightly higher scrutiny because the parties are already in a fiduciary relationship as spouses.

Postnuptial agreements are commonly used when:

• A significant financial change occurs during the marriage (inheritance, business launch, career shift)
• One spouse wants to reconcile after a separation but needs financial protections in place
• The couple failed to execute a prenup before the wedding

Enforceability Requirements

Nebraska courts will enforce a prenuptial or postnuptial agreement if it meets these standards:

Voluntary execution: Both parties signed willingly, without duress, coercion, or undue pressure. An agreement signed the night before the wedding — when walking away from the ceremony would cause severe personal and financial embarrassment — faces heightened scrutiny.

Full financial disclosure: Both parties made complete and honest disclosure of their assets, debts, income, and financial obligations before signing. If one spouse hid a $500,000 investment account, the agreement is vulnerable to challenge.

Not unconscionable: The terms cannot be manifestly unfair at the time of enforcement. An agreement that leaves one spouse destitute while the other retains millions may be struck down even if it was technically voluntary.

Independent legal counsel: While Nebraska does not strictly require both parties to have separate attorneys, courts are far more likely to enforce an agreement when both spouses had the opportunity to consult independent counsel before signing. A spouse who signed without legal advice — especially if the agreement was drafted entirely by the other spouse's attorney — has a stronger argument for setting it aside.

Common Reasons Agreements Get Thrown Out

Incomplete disclosure: The most frequent basis for invalidation. If one spouse failed to disclose significant assets or debts before signing, the other spouse did not make an informed decision.

Duress or coercion: Presenting an agreement for the first time days before the wedding, or conditioning the marriage on signing, raises duress arguments. Courts give more weight to agreements signed well in advance with adequate time for review.

Changed circumstances making enforcement unconscionable: An agreement signed when both spouses were earning similar incomes may become unconscionable if one spouse gave up their career to raise children for 15 years and the agreement waives all alimony.

Failure to follow formalities: The agreement must be in writing and signed by both parties. Oral agreements about property division are not enforceable.

How Prenups Interact with Property Division

If you have a valid prenuptial agreement and are now divorcing, your property division will follow the agreement's terms rather than § 42-365's equitable distribution framework. But the court still reviews the agreement for unconscionability at the time of enforcement — not just at the time of signing.

If you are divorcing without a prenup, Nebraska's default equitable distribution rules apply. Understanding how the court classifies, values, and divides marital property becomes essential to protecting your financial interests.
