Nebraska Prenuptial Agreement
Nebraska prenuptial agreements are governed by the Uniform Premarital Agreement Act, Neb. Rev. Stat. §§ 42-1001 to 42-1011. Courts apply single review only — unconscionability is assessed at signing, not additionally at divorce — and challengers must prove either involuntary execution, or unconscionability at signing plus inadequate disclosure and lack of financial knowledge. Spousal support waivers are enforceable with a minimum of public assistance eligibility.
Bottom line: Nebraska earns an A grade. Single review, a demanding challenge standard, and a clear alimony floor at public assistance eligibility give Nebraska prenups more certainty than most other states.

Nebraska Prenup Laws: Key Statutes Explained
Neb. Rev. Stat. §§ 42-1001 to 42-1011
Separate Property
All assets can remain separate property, avoiding costly divorce settlements. Joint assets and debts titled in both names are split 50/50 as marital property.
Unconscionability Single Review (Pro-Prenup)
Nebraska reviews prenuptial agreements for unconscionability ONLY at execution (signing), not at enforcement (divorce). This prevents courts from second-guessing agreements based on changed circumstances during marriage, providing greater certainty and discouraging litigation challenges.
Unconscionability Standard — § 42-1006 Two-Prong Test
A prenup is unenforceable if the challenging party proves: (1) involuntary execution due to coercion or undue pressure; OR (2) the agreement was unconscionable at execution AND (a) lacked fair and reasonable disclosure of the other's property/obligations, (b) no written waiver of disclosure, AND (c) challenging party lacked adequate knowledge of the other's finances.
Voluntariness — Five-Factor Test
Nebraska courts assess voluntariness under the Edwards/Mamot five-factor test: (1) proximity of execution to the wedding or surprise in presentation; (2) presence, absence, or opportunity for independent counsel; (3) inequality of bargaining power; (4) full disclosure of assets; and (5) understanding of rights being waived.
Spousal Support Public Assistance Minimum
Courts may override spousal support waivers if enforcement would make one party eligible for public assistance at separation or divorce. However, courts can only require support "to the extent necessary to avoid that eligibility" under § 42-1006(2). This is the sole statutory basis for post-execution review.
Timing
No minimum specified, but we recommend signing the prenup 60+ days before the wedding, with both parties having 2-3 weeks to review the final version to minimize challenge risk. Reach out to an attorney at least 4-6 months before the wedding with your draft prenup. Better yet, sign the prenup before proposing.
Independent Counsel
Not required, but separate counsel dramatically strengthens enforceability if the agreement is later challenged. Nebraska courts closely scrutinize whether parties had opportunity for independent legal review, particularly when combined with time pressure or bargaining-power disparities.
Financial Disclosure
"Fair and reasonable disclosure" of property and financial obligations required under § 42-1006, or written waiver. PerfectPrenup includes both. Itemized schedules of assets, debts, income, and business interests are protection; vague references are a liability.
High Burden to Challenge
Challenging party must prove either involuntary execution or unconscionability plus lack of disclosure by preponderance of evidence. Nebraska courts enforce premarital agreements as contracts under ordinary contract principles but subject voluntariness to close scrutiny.
Severability
Unconscionability of a single clause does not void the entire agreement if the prenup contains a severability clause. Nebraska courts will strike only the offending provision and enforce the rest. Including explicit "separate and divisible" language tracks what courts have credited.
Child Support and Custody
Child support and custody clauses are unenforceable under § 42-1004(2) and could undermine the entire agreement. Do not include.
Nebraska Prenuptial Agreement Court Cases
Mamot v. Mamot, 283 Neb. 659, 813 N.W.2d 440 (2012)
The Nebraska Supreme Court held a premarital agreement unenforceable for involuntary execution where the wealthier husband (>$1M assets) presented the agreement to his stay-at-home fiancée five days before the wedding with a "sign or no wedding" ultimatum after she had already paid for invitations, venue, and vendors.
Edwards v. Edwards, 16 Neb. App. 297, 744 N.W.2d 243 (2008)
The Nebraska Court of Appeals upheld the premarital agreement overall but struck a single severable provision capping temporary alimony at six months as unconscionable, allowing the wife to keep $46,000 in temporary alimony (vs. the agreement's $12,000 cap) plus $50,000 in permanent alimony under the agreement.
Seemann v. Seemann (Seemann I), 316 Neb. 671, 6 N.W.3d 502 (2024)
The Nebraska Supreme Court enforced the premarital agreement but construed it to incorporate the active-appreciation rule, forcing the trial court to add $1,347,666 in LLC appreciation, $80,000 in carpet/tile, and $27,768 in professional-corporation value back into the marital estate ($1,405,434 total correction).
Seemann v. Seemann (Seemann II), 318 Neb. 643 (2025)
On a second appeal, the Nebraska Supreme Court again enforced the agreement but reversed the trial court's 54.75%/45.25% split, holding that the agreement's "divided equally" language required a strict 50/50 division of the entire marital estate rather than just listed assets.
Auxier v. Auxier, 32 Neb. App. 230 (2023)
The Nebraska Court of Appeals enforced the agreement in full — including its alimony waiver — and reversed the trial court's $54,000 alimony award to a disabled wife earning $615/month in Social Security, holding that unconscionability must be judged at execution and that §42-1006(2)'s public-assistance exception is the sole post-execution ground for overriding an alimony waiver.
Simons v. Simons, 312 Neb. 136, 978 N.W.2d 121 (2022)
The Nebraska Supreme Court enforced a title-based premarital agreement and confirmed that equitable remedies like constructive trust may operate within the agreement's framework to reclassify solely-titled LLC interests as jointly-titled marital property.
In re Estate of McConnell, 28 Neb. App. 303, 943 N.W.2d 722 (2020)
The Nebraska Court of Appeals enforced the premarital agreement as written but construed its waivers narrowly, holding that a spouse's waiver of rights in the decedent's "Separate Property" did not waive wrongful-death proceeds absent explicit language to that effect.
Cook v. Cook, 26 Neb. App. 137, 918 N.W.2d 1 (2018)
The Nebraska Court of Appeals enforced a stipulated premarital agreement providing for separate ownership of present and future property, preserving the husband's agricultural assets (cow, corn, yearling steers, rental income) as separate property because the parties had followed the agreement's separate-finances regime in practice.
5-Step Checklist: How to Sign & Execute a Prenup in Nebraska
Step 1: Download and read the Nebraska prenuptial agreement
Start with our free template. It is written for Nebraska-specific statutes and case law under Neb. Rev. Stat. §§ 42-1001 to 42-1011 (Uniform Premarital Agreement Act). Read it in full — know what you are getting into legally with marriage. The 15+ pages is written thoroughly to include rebuttals to common legal challenges and fallback provisions.
Step 2: Draft changes on your own
See a clause you don't like? Copy it into an AI like Claude, explain what you'd like to change or what you want the clause "to do." Save any changes as a separate alternate version — don't overwrite the original. Bring both versions to your attorney review. Note: AI is often gender-biased and crafts terms beyond what is legally required. Push back on its output.
Step 3: Find a matrimonial or divorce lawyer in Nebraska
Find a matrimonial or divorce attorney in your state. Avvo, Findlaw, and Justia are good. Look for someone with 10+ years experience. Call or email and ask them how much to review your draft prenup and help with signing. Send them your draft.
Step 4: Meet your lawyer 4–6 months before the wedding
Our recommendation: sign the prenup before proposing. That way, you both get the legal work out of the way, and you know this is the right person to marry. Already proposed? 4–6 months before the wedding should leave you enough time to give your spouse 1–2 weeks to review the final draft and have it signed 60+ days before the wedding. The Nebraska Supreme Court invalidated an agreement presented 5 days before the wedding with a "sign or no wedding" ultimatum (Mamot) — last-minute pressure is one of the most successful challenge grounds.
Step 5: Review and sign the prenup with your attorney
Nebraska's execution requirements are straightforward: the agreement must be in writing and signed by both parties under § 42-1003. Review and sign the agreement with an attorney, who can also serve as a notary. Each party keeps a signed original, and so should each party's attorney. Store yours somewhere secure like a safety deposit box. Create a .pdf and save it via a backup drive and email.
Nebraska Prenuptial Agreement: Frequently Asked Questions (2026)
1. Are prenups enforceable in Nebraska?
Yes. Nebraska adopted the Uniform Premarital Agreement Act in 1994, codified at Neb. Rev. Stat. §§ 42-1001 to 42-1011. A prenup is enforceable if it is in writing, signed by both parties, executed voluntarily, and not unconscionable at the time of signing. The challenger bears the burden of proving otherwise under § 42-1006.
2. How much does a prenup cost in Nebraska?
The average attorney-drafted prenup in Nebraska costs $1,200–$2,200,. With PerfectPrenup saving hours on attorney drafting, a prenup can be reviewed and signed with an attorney for $500-$1,000 per side. Each spouse needs independent counsel.
3. How long before the wedding should a prenup be signed in Nebraska?
No statutory minimum exists, but timing is critical to enforceability. The Nebraska Supreme Court invalidated an agreement signed 5 days before the wedding under a "sign or no wedding" ultimatum in Mamot v. Mamot (2012). Best practice: sign 60+ days before the ceremony, with the final draft delivered 2–3 weeks before signing, and engage an attorney 4–6 months before the wedding.
4. Can a prenup waive alimony in Nebraska?
Yes. Neb. Rev. Stat. § 42-1004(1)(d) expressly permits modifying or eliminating spousal support. The only override is § 42-1006(2): if the waiver would make a spouse eligible for public assistance at separation or divorce, a court may order support — but only "to the extent necessary to avoid that eligibility." Auxier v. Auxier (2023) confirmed this is the sole post-execution ground.
5. Does Nebraska require lawyers for a prenup?
No. Nebraska does not legally require either party to have counsel. However, independent counsel dramatically strengthens enforceability and weighs heavily in the voluntariness analysis under the Edwards/Mamot five-factor test. A single attorney cannot represent both parties because of the inherent conflict of interest.
6. How can a prenup be invalidated or thrown out in Nebraska?
Under § 42-1006, the challenging spouse must prove either (1) involuntary execution, or (2) the agreement was unconscionable at signing AND lacked fair disclosure AND no written waiver of disclosure AND no reasonable knowledge of the other party's finances. Only one prong needs to be proved. Unconscionability is decided by the court as a matter of law.
7. What can a Nebraska prenup include?
Under § 42-1004, a Nebraska prenup can cover: property rights; disposition of property on separation, divorce, or death; spousal support modification or elimination; wills and trusts; life insurance death benefits; choice of law; and any other matter not violating public policy. It CANNOT adversely affect child support.
8. Are postnuptial agreements valid in Nebraska?
No. Nebraska is one of the few states where postnuptial property agreements are void as against public policy under Devney v. Devney (2016). If you want to set terms for property division or alimony, it must be done before the wedding as a prenup. This is a critical distinction from neighboring states.
9. Does a Nebraska prenup need to be notarized?
No. Neb. Rev. Stat. § 42-1003 requires only that the agreement be in writing and signed by both parties — no witnesses or notary are statutorily required. However, notarization is strongly recommended as evidence of voluntary execution and deters later challenges claiming forgery or duress.
10. What happens without a prenup in Nebraska?
Nebraska is an equitable-distribution state under Neb. Rev. Stat. § 42-365. Courts divide marital property by judicial discretion (not automatic 50/50), and even appreciation on separate assets during marriage is presumed marital under the active-appreciation rule. A surviving spouse also gains automatic elective-share rights under § 30-2313, which a prenup can waive.
11. Can a prenup protect a family farm, business, or inheritance in Nebraska?
Yes — this is one of the most common reasons Nebraskans sign prenups. Cook v. Cook (2018) upheld a separate-property agreement covering farmland, livestock, and agricultural equipment. Express language is required: In re Estate of McConnell (2020) held that waivers are construed strictly against the drafter, so "Separate Property" language did not waive wrongful-death proceeds absent explicit wording.
12. Does a Nebraska prenup cover wrongful death proceeds?
Only if the agreement explicitly waives them. Under In re Estate of McConnell (2020), wrongful-death proceeds are not a property right of the decedent's estate and are not contemplated as waived unless the prenup specifically says so. If you intend to waive claims against your spouse's recovery (or protect your own), include express wrongful-death language.
