Infidelity Clauses in Prenups in Nebraska: Complete 2026 Legal Guide
Infidelity clauses in Nebraska prenuptial agreements face significant enforceability challenges because Nebraska operates as a purely no-fault divorce state under Neb. Rev. Stat. § 42-361. While couples can include adultery-related provisions in their prenups, Nebraska courts apply strict public policy scrutiny to any clause that effectively penalizes marital misconduct. An infidelity clause prenup Nebraska couples draft must comply with the Uniform Premarital Agreement Act (UPAA) codified at Neb. Rev. Stat. §§ 42-1001 to 42-1011, which permits provisions addressing property and spousal support but prohibits terms violating public policy. The average Nebraska attorney charges $1,280 for flat-fee prenuptial agreement drafting, though costs range from $1,000 to $10,000 depending on complexity.

What Is an Infidelity Clause in a Nebraska Prenup?
An infidelity clause in a Nebraska prenuptial agreement is a contractual provision that imposes financial consequences if either spouse commits adultery during the marriage. Nebraska courts have not definitively ruled on infidelity clause enforceability, but the state's no-fault divorce framework under Neb. Rev. Stat. § 42-361 creates substantial obstacles for enforcement. Typical cheating prenup penalty provisions include: forfeiture of property rights, increased alimony payments to the faithful spouse, reduced or eliminated spousal support for the cheating party, or lump-sum payments ranging from $25,000 to $500,000. Under Neb. Rev. Stat. § 42-1004, Nebraska prenups may include "any other matter not in violation of public policy or a statute imposing a criminal penalty," leaving adultery clause prenuptial provisions in a legal gray zone.
Types of Infidelity Clauses
Nebraska couples draft several variations of cheating clauses, each with different enforceability risks:
- Property forfeiture clauses: The cheating spouse forfeits a percentage (typically 10%-25%) of their marital property share
- Alimony trigger clauses: Adultery activates spousal support that would otherwise be waived
- Lump-sum penalty clauses: Fixed dollar amounts ($50,000-$500,000) payable upon proven infidelity
- Asset retention clauses: The faithful spouse retains specific assets (marital home, retirement accounts) regardless of equitable division
- Lifestyle clause prenup provisions: Broader behavioral requirements that may include fidelity among other marital expectations
Nebraska's No-Fault Divorce System and Infidelity Clauses
Nebraska recognizes only no-fault divorce, meaning neither spouse must prove wrongdoing to end the marriage. Under Neb. Rev. Stat. § 42-361, the sole ground for dissolution is that the marriage is "irretrievably broken" with no reasonable prospect of reconciliation. This statutory framework creates tension with infidelity clauses because enforcing adultery penalties effectively reintroduces fault concepts that Nebraska law explicitly eliminated. The Nebraska Supreme Court has stated that "neither the granting, denial, or reduction of alimony nor the division of property are to be considered as punitive" under the no-fault system.
How No-Fault Status Affects Enforceability
Nebraska courts weighing infidelity clause enforceability must balance two competing interests: contractual freedom under the UPAA versus the state's public policy commitment to no-fault divorce. California's influential Diosdado v. Diosdado (2002) decision invalidated a $50,000 adultery penalty, reasoning that such provisions impermissibly circumvent no-fault principles. While Nebraska has not issued a comparable ruling, the Diosdado rationale applies directly to Nebraska's identical no-fault framework. States that have enforced infidelity clauses (Pennsylvania, Tennessee, Indiana) typically permit fault-based divorce grounds, which Nebraska does not.
Drafting an Enforceable Infidelity Clause in Nebraska
Nebraska couples seeking to include infidelity provisions in prenuptial agreements should structure clauses to maximize enforceability while minimizing public policy concerns. The most defensible approach frames adultery provisions as alimony modifications rather than punitive penalties. Under Neb. Rev. Stat. § 42-1006, prenups modifying spousal support are generally enforceable unless enforcement would cause a spouse to become eligible for public assistance. Courts distinguish between "penalty clauses" (likely unenforceable) and "conditional support provisions" (potentially enforceable) based on the clause's purpose and proportionality.
Best Practices for Nebraska Infidelity Clauses
Attorneys drafting infidelity clauses in Nebraska prenups should follow these guidelines:
- Frame provisions as conditional spousal support rather than penalties
- Ensure financial consequences are proportional to marital assets (10%-20% adjustments, not forfeitures)
- Define "infidelity" precisely (physical acts only vs. emotional affairs)
- Include evidence standards (clear and convincing proof, not mere allegations)
- Provide for independent verification (private investigator reports, admissions)
- Avoid provisions that would impoverish the cheating spouse
- Ensure both parties receive independent legal counsel (average cost: $1,280 per party)
- Complete full financial disclosure per Neb. Rev. Stat. § 42-1006(b)
Sample Clause Language (For Illustration Only)
A properly structured Nebraska infidelity clause might read: "In the event of marital dissolution where clear and convincing evidence establishes that [Spouse A] engaged in sexual relations with a person other than [Spouse B] during the marriage, [Spouse A] agrees to pay spousal support of $2,500 per month for 36 months, notwithstanding any other spousal support waiver in this agreement." This language avoids punitive framing while creating financial consequences tied to support rather than property division.
Enforceability Factors Under Nebraska Law
Nebraska courts apply Neb. Rev. Stat. § 42-1006 to determine prenup enforceability, examining whether the challenging party signed voluntarily and whether the agreement was unconscionable at execution. Infidelity clauses face additional scrutiny under the "public policy" exception in Neb. Rev. Stat. § 42-1004(a)(8), which prohibits provisions violating Nebraska public policy. The party seeking to enforce the infidelity clause bears the burden of proving validity, while the challenging party must prove involuntariness or unconscionability.
Voluntariness Analysis
Nebraska courts examine five factors when assessing whether a prenup was signed voluntarily:
| Factor | Court Consideration |
|---|---|
| Timing | Proximity to wedding date (presenting agreement 48 hours before ceremony suggests coercion) |
| Counsel | Whether both parties had independent attorneys |
| Bargaining Power | Age differential, sophistication, education levels |
| Disclosure | Completeness of financial information exchanged |
| Understanding | Whether parties comprehended the agreement's legal effect |
Unconscionability Standard
A prenup is unconscionable if it is so one-sided that it "shocks the conscience" of the court at the time of execution. Infidelity clauses providing 100% property forfeiture or multi-million dollar penalties may constitute procedural or substantive unconscionability. Nebraska courts have not established specific dollar thresholds, but clauses imposing penalties exceeding 25% of the marital estate likely face heightened scrutiny.
Property Division Impact Without Enforceable Infidelity Clause
Even without an enforceable infidelity clause, adultery can indirectly affect property division in Nebraska divorce proceedings. Under Neb. Rev. Stat. § 42-365, courts divide marital property equitably (not equally) based on statutory factors including each spouse's contributions and the "general equities of the situation." While infidelity itself is not a statutory factor, related conduct may influence division outcomes.
Economic Misconduct and Dissipation of Assets
Nebraska courts consider "dissipation of marital assets" when one spouse depletes marital funds for purposes unrelated to the marriage. If a cheating spouse spent $50,000 on affair-related expenses (gifts, travel, hotels, romantic dinners), the court may award the faithful spouse a larger share of remaining assets to compensate. The dissipating spouse's share is reduced by the amount wasted, effectively creating a financial consequence for infidelity without requiring an explicit prenup clause.
Division Ranges in Nebraska
Nebraska courts typically divide marital property within these ranges:
- Short marriages (under 5 years): 40%-50% to each spouse
- Medium marriages (5-15 years): 33%-50% to each spouse, weighted toward lower-earning spouse
- Long marriages (15+ years): Often closer to 50%-50%, with adjustments for disparate earning capacity
Alternative Approaches to Infidelity Clauses
Given enforceability uncertainties, Nebraska couples seeking protection against infidelity may consider alternative prenup provisions that achieve similar objectives without triggering public policy concerns.
Postnuptial Agreements
Nebraska recognizes postnuptial agreements under Neb. Rev. Stat. § 42-1011, which extends UPAA provisions to agreements made during marriage. A postnuptial agreement executed after discovery of infidelity (but before divorce filing) may receive greater enforcement because the cheating spouse's conduct is already established, and the agreement reflects current rather than hypothetical circumstances.
Sunset Clauses
Rather than infidelity triggers, couples may include "sunset clauses" that phase out protective provisions over time. For example: "This agreement shall terminate automatically upon the 10th wedding anniversary if no divorce action has been filed." This approach rewards marital longevity without penalizing specific misconduct.
Asset Protection Trusts
Nebraska permits domestic asset protection trusts that can shield separate property from claims in divorce. Establishing trusts before marriage provides protection without relying on potentially unenforceable infidelity clauses.
How Nebraska Courts Handle Infidelity in Divorce
Nebraska's no-fault system means courts cannot deny divorce or impose penalties based solely on adultery. However, infidelity evidence may affect proceedings in limited circumstances.
Custody Considerations
Under Neb. Rev. Stat. § 42-364, courts determine custody based on the child's best interests. While adultery alone does not affect custody, a parent's affair partner's criminal history, substance abuse, or other concerning behavior may be relevant. Courts examine whether the affair exposed children to harmful situations or destabilized the home environment.
Alimony Implications
Under Neb. Rev. Stat. § 42-365, courts award alimony based on need, ability to pay, earning capacity, and marital contributions. Infidelity is not a statutory alimony factor, but courts may consider related economic conduct. Average alimony awards in Nebraska range from $500 to $3,000 per month for 2-10 years, depending on marriage duration and income disparity.
Comparison: Nebraska vs. Other States
Understanding how Nebraska's approach compares to other jurisdictions helps couples evaluate their options.

| Nebraska | Yes | Uncertain (likely difficult to enforce) | Neb. Rev. Stat. § 42-361 |
| California | Yes | Generally unenforceable | Diosdado v. Diosdado (2002) |
| Florida | Yes | Potentially enforceable | Weymouth (2012) - upheld conditional alimony |
| Pennsylvania | No | More likely enforceable | Permits fault-based divorce |
| Tennessee | No | More likely enforceable | Permits fault-based divorce |
| Indiana | Yes | Reasonably enforceable | Must be "fair and reasonable" |
| Nevada | Yes | Generally unenforceable | Parker v. Green |
Cost of Creating a Nebraska Prenup with Infidelity Clause
Nebraska attorneys charge an average of $1,280 for flat-fee prenuptial agreement drafting in 2026, though costs range from $1,000 to $10,000 depending on asset complexity. Agreements containing infidelity clauses typically fall at the higher end of this range because they require additional drafting care and may involve more negotiation.
