Nebraska: Prenuptial Agreement Requirements

Requirements one by one

Nebraska uses the Uniform Premarital Agreement Act

Neb. Rev. Stat. §§ 42-1001 to 42-1011 comprise Nebraska's Uniform Premarital
Agreement Act. Neb. Rev. Stat. § 42-1011 applies it to agreements executed on
or after July 16, 1994. Neb. Rev. Stat. § 42-1002(1) defines a prenup as an
agreement between prospective spouses made in contemplation of marriage and
intended to become effective upon marriage.

Nebraska omitted the model Act's usual amendment section. That omission matters
after marriage because Nebraska case law generally rejects ordinary
postnuptial property agreements.

Both parties must sign a writing

Section 42-1003 states the basic form in one sentence: “A premarital agreement
must be in writing and signed by both parties.” Section 42-1005 makes the
agreement effective upon marriage, not merely upon signing.

Nebraska's form section does not include the familiar uniform-act sentence that
the agreement is enforceable without consideration. The general statute of
frauds separately requires a signed writing for an agreement made upon
consideration of marriage. This page therefore does not attribute a
no-consideration rule to § 42-1003.

The Act adds no notary or witness formality

The current Act's stated form is the signed writing. It does not add
notarization, acknowledgment, witnesses, attestation, an oath, or recording as
a general validity condition for the prenup itself.

A separate deed, trust, beneficiary designation, or other instrument used to
carry out a prenup term can have its own execution or recording rules. Those do
not become universal formalities for the agreement under § 42-1003.

Disclosure is part of a combined defense

Section 42-1006(1)(b) requires execution-time unconscionability and all three
listed disclosure failures: no fair and reasonable disclosure, no voluntary
express written waiver of additional disclosure, and no actual or reasonably
available adequate knowledge.

Those requirements are conjunctive. Missing financial schedules alone do not
complete this statutory defense if a qualifying written waiver or adequate
knowledge defeats another required element.

Counsel and timing inform voluntariness

The Act imposes no independent-counsel mandate, written counsel-waiver form,
final-draft review period, or fixed number of days before the wedding.

The official § 42-1006 annotations summarize Mamot's voluntariness factors.
They include pressure from wedding proximity or surprise, counsel or a real
opportunity to consult counsel, bargaining power and sophistication, financial
disclosure, and understanding of the rights waived or the agreement's purpose.
Counsel and timing are therefore fact-sensitive factors even though they are
not standalone formalities.

The statutory enforcement routes are distinct

Neb. Rev. Stat. § 42-1006 supplies two routes to nonenforcement. Involuntary
execution is sufficient by itself. The alternative requires unconscionability
when the agreement was executed together with all three disclosure failures.

The court decides unconscionability as a matter of law. The section does not
state a general enforcement-time unconscionability or changed-circumstances
test for every term.

Support waivers have a narrow floor

Neb. Rev. Stat. § 42-1004(1)(d) permits modification or elimination of spousal
support. Edwards holds that this authority reaches both permanent and
temporary support.

Section 42-1006(2) creates a narrow override if the term would cause
public-assistance eligibility at separation or dissolution: the court may
order enough support to avoid that eligibility. Edwards separately preserves
the court's authority to order litigation funding needed to maintain or defend
the dissolution action.

Child support and custody remain protected

Section 42-1004(2) says a prenup may not adversely affect a child's right to
support. Personal-rights terms also may not violate public policy or a statute
imposing a criminal penalty.

Custody and parenting remain later court decisions. Under § 42-364, custody
must be based on the child's best interests, and a parenting plan created by
the parties enters the decree only if the court approves it. Child support is
set with the parents' earning capacity and Supreme Court guidelines in view.

Nebraska supplies no ordinary amendment route

Unlike most Uniform Premarital Agreement Acts, §§ 42-1001 to 42-1011 contain no
section authorizing amendment or revocation by another signed writing after
marriage.

Devney v. Devney holds that Nebraska statutes do not authorize postnuptial
property agreements unless they are concurrent with separation or divorce,
and that an ordinary postnuptial property agreement is void. A generic clause
promising that the spouses can later amend the prenup by a notarized writing
therefore should not be presented as a Nebraska statutory route.

What trips people up

• There is no standard Uniform Act amendment section. Nebraska's Act jumps
  from effect upon marriage in § 42-1005 to enforcement in § 42-1006.
• The disclosure defense is conjunctive. Execution-time
  unconscionability and all three disclosure failures must appear together.
• The support override is not general fairness review. It is limited to
  avoiding public-assistance eligibility; Edwards separately preserves
  necessary litigation funding.

Common questions

Must each prospective spouse have a lawyer?

The Act does not make independent counsel a formal requirement. But Mamot
treats counsel or a genuine opportunity to consult counsel as one factor in
whether execution was voluntary.

Can the parties waive further financial disclosure?

Section 42-1006(1)(b)(ii) recognizes a voluntary express written waiver of
disclosure beyond what was provided. Adequate knowledge is a separate
alternative within the combined enforcement defense.

What if the marriage is declared void?

Under § 42-1007, an agreement that otherwise would have been a prenup is
enforceable only to the extent necessary to avoid an inequitable result.
Neb. Rev. Stat. § 42-1008 tolls limitations during marriage but preserves
equitable time defenses such as laches and estoppel.
