Are Postnuptial Agreements Enforceable in Nebraska?
Under current Nebraska law, a postnuptial agreement that predetermines how spouses’ property will be divided in a possible future separation or divorce is generally void if it is not attendant upon an actual or imminent separation or dissolution. The Nebraska Supreme Court stated that rule in Devney v. Devney, 295 Neb. 15, 886 N.W.2d 61 (2016).
That does not mean every agreement signed after marriage is invalid. Nebraska law permits a written waiver of certain rights in a spouse’s estate under Neb. Rev. Stat. § 30-2316. Spouses may also enter a written property settlement agreement under § 42-366 when the agreement is attendant upon an actual separation or dissolution. An estate waiver addresses rights at death, while a settlement agreement addresses an existing separation or divorce.
For couples who are not yet married, Nebraska’s Uniform Premarital Agreement Act provides a statutory framework for addressing certain property rights, spousal support, and the disposition of property at separation, divorce, or death. A premarital agreement must be made in contemplation of marriage, be in writing, and be signed by both parties. Enforceability is not automatic and may depend on voluntariness and the disclosure and knowledge requirements contained in Neb. Rev. Stat. § 42-1006.
For already-married couples, the better first question is often not, “Can we get a postnup?” It is, “What are we trying to accomplish?” Estate planning, preserving evidence of a nonmarital interest, business succession, and resolving an actual separation require different legal tools. Because Nebraska treats postnuptial agreements differently from many other states, an online form prepared for another jurisdiction may not provide the protection Nebraska spouses expect.
The Short Answer
Nebraska generally does not enforce a postnuptial agreement that allocates property rights upon an unanticipated future separation or divorce when the agreement is not connected to an actual or imminent separation or dissolution.
That is the central rule from Devney. The Nebraska Supreme Court concluded that Nebraska statutes did not authorize the spouses’ postnuptial property agreement and that such agreements remained contrary to Nebraska public policy when they attempted to govern a possible future divorce outside the context of an actual or imminent separation.
The timing and purpose of the agreement matter. A document signed after marriage may still be legally meaningful if it is a valid estate-rights waiver, an agreement connected to an actual separation or dissolution, or another properly structured ownership or estate-planning document.
What generally does not work is asking spouses to sign a private contract during the marriage that fixes how their property will be divided if an unanticipated divorce occurs years later.
What Did the Nebraska Supreme Court Decide in Devney?
In Devney v. Devney, the spouses signed a postnuptial agreement several months after marrying. The agreement addressed how their property would be treated if the marriage later ended, but there was no evidence that separation or divorce was then being contemplated or was imminent.
The Nebraska Supreme Court held that the agreement was void to the extent it settled the spouses’ property rights upon an unanticipated separation or divorce. The Court distinguished that agreement from a written property settlement made in connection with an actual separation or dissolution under Neb. Rev. Stat. § 42-366.
The Court also rejected the idea that Nebraska’s statute authorizing waivers of inheritance rights, § 30-2316, created broad authority for all postnuptial property agreements. Section 30-2316 concerns rights arising at death. It does not authorize an agreement allocating property in a later divorce.
This distinction cannot be solved merely by careful wording, notarization, or using a form that may be enforceable elsewhere. Formalities do not supply statutory authority that Nebraska law otherwise does not provide.
What Agreements Can Nebraska Spouses Make After Marriage?
Nebraska law recognizes several narrower forms of planning after marriage. Each serves a different purpose and should be evaluated on its own terms.
Estate-Rights Waivers Under § 30-2316
Neb. Rev. Stat. § 30-2316 permits a spouse to waive all or part of the surviving spouse’s right of election, homestead allowance, exempt property, and family allowance. The waiver may be made before or after marriage, but it must be in writing and signed by the spouse giving up those rights.
This is an estate-planning tool. It determines whether a surviving spouse may assert specified statutory rights after the other spouse dies. It does not determine how property will be classified or divided if the spouses divorce.
An estate-rights waiver may be useful in a second marriage when one or both spouses have children from an earlier relationship. It may also be considered when spouses want to coordinate their rights with wills, trusts, beneficiary designations, deeds, or a broader estate plan.
The waiver is not immune from challenge. Under § 30-2316, it is unenforceable if the surviving spouse proves that the waiver was not voluntary.
A waiver is also unenforceable if the surviving spouse proves that it was unconscionable when executed and that, before signing, the surviving spouse:
Was not provided a fair and reasonable disclosure of the decedent’s property or financial obligations;
Did not voluntarily and expressly waive further disclosure in writing; and
Did not have, or reasonably could not have had, adequate knowledge of the decedent’s property or financial obligations.
All three additional conditions must accompany the unconscionability finding under that statutory alternative.
A dispute over a surviving spouse’s statutory estate rights often arises in the probate or estate context. Nebraska county courts have exclusive original jurisdiction over matters relating to decedents’ estates, subject to statutory exceptions. Trusts, beneficiary designations, jointly owned property, and other nonprobate transfers may require separate analysis.
Because an estate waiver may affect substantial inheritance rights, spouses should not rely on a generic form without Nebraska-specific legal review. The waiver should be coordinated with the rest of the estate plan rather than treated as a stand-alone document.
Property Settlements Connected to Separation or Dissolution
Neb. Rev. Stat. § 42-366 permits spouses to enter a written property settlement agreement to resolve disputes attendant upon their separation or the dissolution of their marriage.
The agreement may address maintenance and the disposition of property. It may also contain proposed terms concerning the support and custody of minor children, but those child-related terms are not binding on the court.
In a Nebraska dissolution or legal-separation proceeding, the property and maintenance provisions are generally binding unless the court finds the agreement unconscionable after considering the parties’ economic circumstances and other relevant evidence. If the court makes that finding, it may request a revised agreement or enter appropriate orders itself.
Custody, parenting time, parenting plans, and child support are treated differently. Even when parents agree, the court must independently evaluate those issues under Nebraska law. Custody and parenting time turn on the child’s best interests, parenting plans must comply with the Nebraska Parenting Act and receive court approval, and child support is governed by Nebraska’s child-support statutes and guidelines.
The agreement must also be genuinely connected to the separation or dissolution. Changing the title of an intact-marriage postnup to “property settlement agreement” does not necessarily bring it within § 42-366. The timing, circumstances, purpose, and substance of the agreement may all matter.
If a dissolution or legal-separation case is pending, the settlement must be evaluated in that court proceeding under Nebraska law. If a court order is already in place, the parties should not assume that a private agreement changes their obligations. They should continue to follow the existing order unless and until the court modifies it.
For clients going through separation or divorce, our firm also offers in-house divorce coaching and, when children are involved, co-parenting coaching as part of the services available to our clients at no additional fee. Coaching may help clients work through communication and transition issues, but it does not replace legal advice, court approval of parenting terms, compliance with existing orders, or mental-health treatment.
Other Ownership and Estate-Planning Documents
Married spouses may use deeds, trusts, beneficiary designations, business agreements, buy-sell agreements, and other documents for legitimate ownership, succession, tax, or estate-planning purposes.
Those documents can have significant legal consequences. They do not, however, automatically control how a Nebraska court will classify or divide property in a later divorce.
For example, a business operating agreement may regulate voting rights, transfers, and relationships among owners. A trust may control how property is managed or distributed. Neither document necessarily prevents a court from determining that a spouse has a marital interest in the value of an asset.
Ownership planning should therefore be described accurately. It may support a broader plan, but it is not a guaranteed substitute for a valid premarital agreement.
How Are Premarital Agreements Different?
Nebraska has expressly adopted the Uniform Premarital Agreement Act, Neb. Rev. Stat. §§ 42-1001 through 42-1011.
Section 42-1002 defines a premarital agreement as an agreement between prospective spouses made in contemplation of marriage and intended to become effective upon marriage. Section 42-1003 requires the agreement to be in writing and signed by both parties.
Under § 42-1004, a premarital agreement may address subjects including:
Rights and obligations in property;
Management and control of property;
Disposition of property upon separation, dissolution, or death;
Modification or elimination of spousal support;
Wills, trusts, and related estate-planning arrangements;
Life-insurance benefits; and
Other lawful matters that do not violate public policy.
A premarital agreement may not adversely affect a child’s right to support.
Enforceability is governed by § 42-1006. A premarital agreement is not enforceable if the party opposing enforcement proves that the agreement was not signed voluntarily.
It may also be unenforceable if that party proves that the agreement was unconscionable when executed and, before signing, the party was not given fair and reasonable financial disclosure, did not voluntarily and expressly waive further disclosure in writing, and did not have or reasonably could not have had adequate knowledge of the other party’s property or financial obligations.
Financial disclosure alone is therefore not the entire enforcement test. Likewise, unconscionability alone is not enough under that statutory alternative. The requirements must be considered together.
Nebraska courts may examine circumstances such as proximity to the wedding, surprise in presenting the agreement, the opportunity to consult independent counsel, bargaining power, financial disclosure, and the parties’ understanding of the rights being waived when evaluating voluntariness.
A premarital agreement may modify or eliminate spousal support, but that provision is not necessarily absolute. If enforcement would cause a spouse to become eligible for public assistance at separation or dissolution, § 42-1006 permits the court to require support to the extent necessary to avoid that eligibility.
Completing a premarital agreement with adequate time, meaningful disclosure, and an opportunity for each person to obtain separate legal advice may reduce later disputes. Those precautions do not guarantee enforcement, but rushing the process can create avoidable questions about voluntariness and understanding.
What Can an Already-Married Couple Realistically Do?
The answer depends on the couple’s actual objective.
If the Concern Is What Happens at Death
A coordinated Nebraska estate plan may be appropriate. Depending on the circumstances, that plan could include wills, trusts, beneficiary designations, deeds, life-insurance planning, and a waiver under § 30-2316.
Each document should be reviewed as part of the same plan. A beneficiary designation, deed, or account registration may override expectations created by a will, and nonprobate property may require different analysis from property administered through probate.
If the Concern Is an Inheritance, Farm, or Business
Preserving a claim that an inheritance, farm interest, or business interest is nonmarital may require careful records, tracing, and ownership planning. Classification and division remain fact-specific and subject to court review in a dissolution.
Important records may include probate documents, gift letters, deeds, account statements, loan histories, business records, tax returns, valuation reports, and evidence showing how marital funds or labor were used.
Before changing title, transferring ownership, or moving property into a trust or entity, consider the possible divorce, probate, tax, creditor, and business consequences. A change that helps one part of a plan can complicate another.
If the Marriage Is Actually Ending
When separation or dissolution is occurring or imminent, the spouses may be able to negotiate a written settlement under § 42-366.
That process may involve financial disclosure, valuation, negotiation, mediation, and review of proposed terms concerning property, debt, maintenance, and children. No settlement eliminates the need to consider the facts, statutory requirements, existing court orders, and the court’s independent responsibilities regarding children.
Why Records Often Matter More Than Labels
Nebraska property division generally involves three steps:
Classifying property as marital or nonmarital;
Valuing the marital assets and liabilities; and
Dividing the net marital estate equitably.
“Equitable” means fair and reasonable under the circumstances. It does not create an automatic 50/50 rule, and Nebraska property division is not governed by a single mathematical formula. Neb. Rev. Stat. § 42-365 directs courts to consider the parties’ circumstances, the length of the marriage, their contributions to the marriage, and other relevant factors.
Property acquired by gift or inheritance ordinarily begins as nonmarital property, but the spouse asserting a nonmarital interest bears the burden of proving it. The evidence must establish both the source of the property and the claimed nonmarital interest.
Using a joint account does not automatically answer the classification question. In Backhaus v. Backhaus, 318 Neb. 891 (2025), the Nebraska Supreme Court upheld a finding that inherited funds remained nonmarital based on the evidence establishing their source, even though the account was jointly held. The decision does not make joint accounts risk-free. It confirms that source, tracing, credibility, and the overall evidence matter.
An asset can also contain both marital and nonmarital components. Marital funds used to reduce principal debt on initially nonmarital property may create a proportionate marital interest. Appreciation attributable to marital money or either spouse’s efforts may also be treated differently from passive appreciation, including in cases involving agricultural land.
Careful titling can make the evidence easier to understand, but title alone may not control. The stronger practice is to preserve the paper trail showing when the asset was acquired, where the funds came from, what happened to them, and how the asset changed during the marriage.
A Generalized Nebraska Example
Consider a hypothetical couple who married without a premarital agreement. Several years later, one spouse inherits an interest in a family farming operation.
The spouses download a postnuptial agreement stating that the farm interest, all income from it, and all future appreciation will belong solely to the inheriting spouse if they later divorce. At the time they sign, they are not separating, and neither spouse anticipates an imminent dissolution.
Under Devney, the provisions attempting to allocate property rights in an unanticipated future divorce would generally be void because the agreement was not attendant upon an actual or imminent separation or dissolution.
That does not automatically make the inherited farm interest marital. The inheritance may still begin as a nonmarital asset. But its later treatment could depend on whether the interest can be traced, whether marital funds reduced related debt, whether either spouse contributed labor, whether distributions were deposited into other accounts, and what caused the asset to appreciate.
If the couple’s real concern was what would happen at death, the more appropriate tools might have included a coordinated estate plan and a § 30-2316 waiver. If the marriage later reached the point of an actual or imminent separation, the spouses could consider negotiating a written settlement under § 42-366.
The label “postnuptial agreement” would not solve the underlying legal problem. The correct tool depends on the event being planned for and the rights the spouses are trying to address.
What Should You Gather Before Meeting With a Nebraska Lawyer?
A useful legal review often begins with the following:
Any existing premarital agreement, postnuptial agreement, separation agreement, court order, will, trust, or power of attorney;
The marriage date and a timeline showing when significant assets and debts were acquired;
Deeds, closing statements, purchase agreements, and loan records;
Bank, investment, and retirement-account statements;
Probate records, trust distributions, gift letters, and other evidence of inheritances or gifts;
Business formation documents, operating agreements, ownership records, financial statements, tax returns, and valuations;
Records of principal payments, improvements, capital contributions, and significant labor devoted to a farm, business, or real estate;
Beneficiary designations for life insurance, retirement accounts, and payable-on-death accounts;
Correspondence and financial disclosures exchanged when any agreement was negotiated; and
A clear description of whether the concern involves death, a possible future divorce, or an actual or imminent separation.
Do not destroy or disregard an existing postnuptial agreement merely because someone says it is unenforceable. Different provisions may serve different purposes, and the agreement may be connected to transfers, estate documents, or other transactions that require separate review.
How Our Firm Approaches Postnuptial Agreement Questions
The first step is identifying the actual objective.
A spouse concerned about probate needs a different plan from a spouse trying to preserve evidence of an inheritance. A business succession issue calls for different documents from an actual divorce settlement. A parenting plan requires a different analysis from a property agreement.
We would rather identify those distinctions early than prepare a document that offers more confidence than legal protection. When estate planning is the real concern, the plan should be built around Nebraska probate and estate-planning law. When separation or divorce is underway, the focus may shift to disclosure, valuation, negotiation, mediation, parenting issues, and a settlement that can properly be submitted for court review.
For clients navigating separation or divorce, our firm offers in-house divorce coaching and, where children are involved, co-parenting coaching as part of our client services at no additional fee. Coaching can assist with communication, decision-making, and transition planning, but it does not change legal rights, replace legal advice or therapy, influence a court’s decision, or excuse compliance with an existing court order.
Frequently Asked Questions
Is a Postnuptial Agreement Enforceable in Nebraska?
A postnuptial agreement that allocates property rights upon an unanticipated future separation or divorce is generally void when it is not attendant upon an actual or imminent separation or dissolution. Nebraska does recognize narrower after-marriage agreements, including estate-rights waivers under § 30-2316 and settlements attendant upon separation or dissolution under § 42-366.
Is Every Agreement Signed After Marriage Invalid?
No. Estate waivers, separation agreements, trusts, deeds, beneficiary designations, and business agreements may all have legal effects when properly used. The important questions are what the document does, what law authorizes it, and whether it is being used for death-time planning, an actual separation, or another legitimate purpose.
We Already Signed a Postnup. Is It Worthless?
Not necessarily. Preserve the agreement, drafts, financial disclosures, correspondence, related deeds, and estate-planning documents so a Nebraska lawyer can review each provision and the circumstances in which it was signed. Some provisions may serve a purpose separate from the clauses attempting to control a future divorce.
Can a Postnup Protect an Inheritance, Farm, or Business?
A postnuptial agreement governed by the rule in Devney generally will not control property division in a later divorce. The underlying asset may still be wholly or partly nonmarital, but the result can depend on tracing, debt payments, marital contributions, appreciation, and the available evidence.
What Does a § 30-2316 Waiver Do?
It permits a spouse to waive some or all rights to an elective share, homestead allowance, exempt property, and family allowance at the other spouse’s death. It is an estate-planning and probate tool, not an agreement governing property division in divorce.
When Can Married Spouses Enter a Property Settlement?
Nebraska law permits spouses to enter a written settlement to resolve disputes attendant upon separation or dissolution. In the resulting court proceeding, property and maintenance provisions are generally binding unless unconscionable, while child-related terms remain subject to independent court review.
Can Parents Decide Custody, Parenting Time, or Child Support in a Postnup?
Parents may propose a parenting plan and child-support terms, but they cannot conclusively bind the court in advance. Nebraska courts must address custody and parenting time according to the child’s best interests and the Parenting Act, and child support remains subject to Nebraska law, the guidelines, and court approval.
Does Equitable Division Mean Everything Is Split 50/50?
No. Equitable division means a division that is fair and reasonable under the circumstances, not automatically equal. The court classifies and values the property before dividing the net marital estate, and the result depends on the evidence and the statutory factors.
Does Putting an Inheritance Into a Joint Account Make It Marital?
Not automatically. The Nebraska Supreme Court’s decision in Backhaus confirms that the source and proof of the funds can matter even when an account is jointly held. Mixing property can still make tracing more difficult, so complete records remain important.
Should We Sign a Premarital Agreement Before the Wedding Instead?
For couples who have not yet married, Nebraska’s Uniform Premarital Agreement Act provides the statutory framework for addressing many property and support issues. The agreement must be in writing and signed, and enforceability may depend on voluntariness and the disclosure and knowledge requirements in § 42-1006.
Can We Privately Change an Existing Divorce or Custody Order?
Do not assume that a private agreement changes an existing court order. Until the court approves a modification, the existing order should be followed, including provisions concerning property transfers, support, custody, parenting time, or other obligations.
