Postnuptial Agreement After Infidelity in Nebraska: 2026 Legal Guide

Nebraska courts do not enforce postnuptial agreements, making a postnup after cheating legally void under state law. In the landmark case Devney v. Devney, 295 Neb. 15 (2016), the Nebraska Supreme Court declared postnuptial property agreements contrary to public policy, stating they have a "deleterious effect on marriages and promote divorce." This means couples who discover infidelity cannot create a binding postnup after cheating in Nebraska to restructure property rights or impose financial consequences. However, Nebraska does recognize separation agreements made during divorce proceedings and limited inheritance waivers under Neb. Rev. Stat. § 30-2316, offering some alternatives for couples navigating the aftermath of an affair.

Key Facts: Postnuptial Agreements in Nebraska

Why Nebraska Does Not Enforce Postnuptial Agreements After Cheating

Nebraska is one of the few states that categorically refuses to enforce postnuptial agreements for property division, making a postnup after infidelity legally worthless in this jurisdiction. The Nebraska Supreme Court established this rule in Devney v. Devney, 295 Neb. 15, 886 N.W.2d 61 (2016), holding that postnuptial property agreements are "void as statutorily unauthorized" and violate public policy. The Court reasoned that such agreements have a "deleterious effect" on marriages by encouraging divorce rather than reconciliation. This ruling affects approximately 15,000 Nebraska couples who file for divorce annually and any who hoped to use postnups as a tool for addressing infidelity.

The practical impact of this prohibition is significant for couples where one spouse has committed adultery. Unlike states such as Florida, Texas, or New York that enforce postnuptial agreements with varying scrutiny levels, Nebraska offers no mechanism for spouses to create binding property agreements after marriage to address infidelity. A postnuptial infidelity clause promising the faithful spouse 70% of marital assets or requiring the cheating spouse to forfeit retirement benefits would be completely unenforceable in Nebraska courts, regardless of how carefully it was drafted or how willingly both parties signed.

The Devney Decision: Nebraska's Landmark Postnuptial Case

The Devney v. Devney case established Nebraska's firm position against postnuptial property agreements. Clarence and Elizabeth Devney married in August 1998 and executed a postnuptial agreement during their marriage. When Clarence filed for divorce in April 2014, the district court initially ruled the postnuptial agreement valid and enforceable. Elizabeth appealed, and the Nebraska Supreme Court reversed in part, declaring that Nebraska statutes do not authorize postnuptial agreements to allocate property rights upon separation or divorce.

The Court cited three fundamental principles in its decision. First, Nebraska has no statutory authority supporting postnuptial property agreements, unlike prenuptial agreements governed by the Nebraska Uniform Premarital Agreement Act. Second, postnuptial agreements were prohibited under common law and remain so absent legislative action. Third, such agreements violate public policy because they undermine marital stability by providing a predetermined exit strategy rather than encouraging couples to work through difficulties. The Nebraska Supreme Court reaffirmed this position in Seemann v. Seemann, 316 Neb. 671 (2024), confirming that Devney remains controlling precedent.

Limited Exception: Inheritance Waivers Under § 30-2316

Nebraska law permits one narrow category of postnuptial agreement: inheritance waivers under Neb. Rev. Stat. § 30-2316. This statute allows spouses to waive their right to elect against the other spouse's will, meaning they can agree to forgo their statutory inheritance rights. An inheritance waiver executed after marriage may be enforceable if it meets strict requirements, but this exception does not extend to divorce property division. The statute should be "strictly construed" according to the Devney court because all postnuptial agreements were void at common law.

For couples addressing infidelity, an inheritance waiver offers limited utility. While a spouse could theoretically agree to receive nothing from the other spouse's estate as a consequence of cheating, this provision only affects what happens at death, not divorce. If the couple divorces before either spouse dies, the inheritance waiver becomes irrelevant because divorce automatically terminates inheritance rights under Nebraska law. Courts estimate that fewer than 5% of postnuptial agreements nationwide focus primarily on inheritance, making this exception of minimal practical value for infidelity situations.

Separation Agreements: Nebraska's Enforceable Alternative

While postnuptial agreements are void, Nebraska does enforce separation agreements made "attendant upon" the spouses' separation or dissolution of marriage. Under Nebraska law, couples may enter into a written property settlement agreement containing provisions for maintenance, property disposition, and child custody when they are actively separating or divorcing. The key distinction is timing: an agreement made during an ongoing marriage with no immediate separation planned is a void postnup, while an agreement made as part of separation or divorce proceedings is an enforceable settlement.

A separation agreement offers significant flexibility for addressing infidelity consequences within Nebraska's legal framework. The agreement can include unequal property division where the faithful spouse receives 60% or more of marital assets, ongoing spousal support obligations, specific asset allocations such as the family home to one spouse, and provisions addressing any debts incurred during the affair. Under Neb. Rev. Stat. § 42-366, these terms become binding on the court unless found unconscionable, and once incorporated into the divorce decree, they are enforceable by contempt of court.

How Adultery Affects Nebraska Divorce Proceedings

Nebraska is a purely no-fault divorce state under Neb. Rev. Stat. § 42-361, meaning adultery has no direct impact on property division or alimony determinations. The sole ground for dissolution is that the marriage is "irretrievably broken," and courts do not assign blame or punish marital misconduct. This no-fault framework affects roughly 8,500 contested divorces annually in Nebraska and means judges cannot award a faithful spouse additional property simply because the other spouse cheated.

However, economic misconduct related to an affair may indirectly affect property division. If one spouse "wasted" marital assets on an extramarital relationship, purchasing gifts, vacations, or apartments for a paramour, the court may consider this dissipation when dividing the marital estate. The burden of proof lies with the spouse claiming dissipation, requiring concrete evidence such as financial records documenting significant expenditures on the affair. Nebraska courts following the equitable distribution framework under Neb. Rev. Stat. § 42-365 generally award each spouse one-third to one-half of the marital estate, but documented dissipation could justify deviation from this standard.

Reconciliation Agreement Alternatives in Nebraska

Couples who wish to reconcile after infidelity without immediately divorcing face limited options in Nebraska because traditional postnuptial reconciliation agreements are void. However, several alternative approaches may provide some structure and accountability. First, couples can work with marriage therapists to create behavioral agreements that, while not legally enforceable, establish clear expectations and consequences for future conduct. Second, spouses can modify estate planning documents, updating wills, beneficiary designations, and trust arrangements to reflect changed circumstances.

Third, couples can create a "contemplation of divorce" separation agreement. If both spouses acknowledge that infidelity has brought the marriage to the brink of dissolution and they are genuinely contemplating separation, an agreement made at this juncture may qualify as attendant upon separation. This approach requires careful legal guidance because Nebraska courts scrutinize the timing and circumstances to determine whether an agreement truly relates to imminent separation or is merely a disguised postnup. Attorney fees for drafting such agreements typically range from $1,500 to $5,000 depending on complexity and assets involved.

Infidelity Clauses and Their Enforceability Nationwide

Understanding Nebraska's strict prohibition requires context about how other states treat postnuptial infidelity clauses. Approximately 28 states enforce postnuptial agreements to varying degrees, while Nebraska joins a minority that either prohibits or severely restricts them. States like Florida, Texas, and Georgia generally enforce postnups if they meet standard contract requirements including voluntary execution, fair disclosure, and consideration. In these states, a postnup after affair discovery might be enforceable, providing the betrayed spouse with predetermined property rights or alimony.

Even in states that enforce postnups, infidelity clauses face additional challenges. Courts often refuse to enforce clauses they deem wildly disproportionate or unconscionable. A clause demanding $5 million for a single act of infidelity might not survive judicial review if it would leave the cheating spouse destitute. Courts also scrutinize whether infidelity is clearly defined, whether the agreement was signed under duress or as retaliation, and whether enforcement would violate public policy of that state.

Steps to Take After Discovering Infidelity in Nebraska

If you have discovered a spouse's infidelity and are considering your legal options in Nebraska, several immediate steps can protect your interests despite the inability to execute a binding postnup. First, document any evidence of marital asset dissipation, gathering bank statements, credit card records, and receipts showing money spent on the affair. This documentation could support a claim for unequal property division during divorce proceedings. Second, consult with a Nebraska family law attorney who can explain your specific rights and options given your circumstances.

Third, assess whether you genuinely want to reconcile or if divorce is more appropriate. If divorce is likely, beginning the process allows you to negotiate a separation agreement that can address infidelity-related concerns. Nebraska's 60-day waiting period means even an amicable divorce takes at least two months, so early action provides time for negotiation. Fourth, if you wish to reconcile, work with your spouse and potentially a therapist to establish boundaries and expectations, understanding these cannot be legally enforced through a postnuptial agreement. The median cost of marriage counseling in Nebraska ranges from $150 to $250 per session, compared to median divorce costs of $11,300 for contested cases.

Property Division Without a Postnuptial Agreement

In the absence of an enforceable postnup after infidelity, Nebraska courts divide marital property according to equitable distribution principles under Neb. Rev. Stat. § 42-365. The court follows a three-step process: first classifying property as marital or nonmarital, second valuing marital assets and liabilities, and third dividing the net marital estate equitably. The "one-third to one-half" rule provides general guidance, with courts typically awarding each spouse between 33% and 50% of marital assets depending on circumstances.

Factors courts consider include the duration of the marriage, contributions to marital property including homemaking and childcare, the economic circumstances of each party, custody arrangements, and sacrifices made by one spouse for the other's benefit. Notably, marital fault including adultery is not a statutory factor, though economic misconduct like dissipation may be relevant. For a marriage lasting 15 years with $500,000 in marital assets, each spouse might expect to receive between $165,000 and $250,000, adjusted for factors like earning capacity disparities or dissipation claims.

Alimony Considerations After Infidelity

Nebraska does not consider marital fault when determining alimony under Neb. Rev. Stat. § 42-365, meaning adultery does not directly affect spousal support awards. The statutory factors focus on economic considerations: circumstances of the parties, duration of the marriage, contributions including caregiving and education, career interruptions, and ability to become self-supporting without harming minor children's interests. Unlike some states that permit fault-based alimony adjustments, Nebraska's no-fault framework treats infidelity as irrelevant to maintenance calculations.

This framework means a postnup after cheating promising increased alimony would be unenforceable on two grounds: first, as a void postnuptial agreement, and second, because it attempts to import fault considerations that Nebraska law excludes. The median alimony award in Nebraska for marriages lasting 10-20 years ranges from $1,000 to $2,500 monthly, typically lasting 50-70% of the marriage duration. These amounts depend on income disparities, not on which spouse caused the marital breakdown.

Filing for Divorce in Nebraska: Procedural Requirements

If reconciliation proves unsuccessful, understanding Nebraska's divorce procedural requirements helps couples move forward efficiently. Under Neb. Rev. Stat. § 42-349, at least one spouse must have resided in Nebraska for one year with the intent to make it their permanent home before filing. An exception exists for military personnel stationed in Nebraska for one year and for couples married in Nebraska who have resided there continuously since the wedding. Filing fees range from $158 to $164 depending on county, with Douglas, Lancaster, and Sarpy counties charging $164.

The 60-day waiting period begins when the respondent is served or files a voluntary appearance waiver. This cooling-off period applies to all divorces regardless of whether they are contested or uncontested. Fee waivers are available for individuals with income at or below 125% of federal poverty guidelines, approximately $19,506 annually for a single person in 2026.
