Nevada: Prenuptial Agreement Requirements

Requirements one by one

Nevada uses the Uniform Premarital Agreement Act

NRS 123A.010-123A.040 identify Chapter 123A as the Uniform Premarital
Agreement Act, define a premarital agreement as one made by prospective
spouses in contemplation of marriage, and supply the basic form rule.

The current official chapter is still the 1989 enactment. Nevada's enforcement
wording is important: execution-time unconscionability stands on its own, while
the disclosure defense separately requires all three listed failures.

The agreement needs a writing and both signatures

NRS 123A.040 says the agreement must be written and signed by both parties. It
is enforceable without consideration, so no separate payment or property
exchange is needed.

Under NRS 123A.060, the agreement becomes effective upon marriage. Signing
before the wedding satisfies the form but does not activate the agreement by
itself.

Chapter 123A does not require a notary or witnesses

The statutory form is the signed writing. Chapter 123A does not add a notary,
acknowledgment, witness, attestation, oath, or recording requirement for basic
validity between the parties.

Separate deeds, trusts, beneficiary designations, or other instruments used to
carry out a term can have their own formalities.

Disclosure has three statutory alternatives

The NRS 123A.080(1)(c) challenge succeeds only if all three conditions are
proved: no fair and reasonable disclosure; no voluntary express written waiver
of further disclosure; and no actual or reasonably available adequate
knowledge of the other party's property or financial obligations.

The waiver must be voluntary, express, and in writing. The statute does not say
that it must be in a separate document.

Nevada has no fixed counsel or timing protection

Chapter 123A does not require separate counsel, a written counsel waiver, a
minimum review period, or a set number of days between signing and the wedding.

Voluntary execution still matters independently. Under NRS 123A.080(1)(a), an
agreement is unenforceable against a party who proves that the party did not
execute it voluntarily.

Unconscionability is a standalone execution-time defense

NRS 123A.060-123A.080 govern effect, amendment, revocation, and enforcement.
The enforcement section supplies three independent routes: involuntary
execution; unconscionability when signed; or all three disclosure failures.

The challenger does not have to combine execution-time unconscionability with
the disclosure conditions. The court decides unconscionability as a matter of
law. Chapter 123A does not state a general enforcement-time unconscionability
review for every term.

Support terms have a public-assistance floor

NRS 123A.050 permits modification or elimination of alimony, support, or
maintenance. NRS 123A.080(2) supplies a targeted override: if the term causes
public-assistance eligibility at separation or dissolution, the court may order
support only to the extent necessary to avoid that eligibility.

That provision is not a general enforcement-time fairness rewrite. It addresses
the specific public-assistance consequence named by the statute.

Child support and custody remain under legal limits

NRS 123A.050(2) says the agreement may not adversely affect a child's right to
support. The same section permits personal-rights terms only when they do not
violate public policy or a statute imposing a criminal penalty.

Physical custody remains for the court. NRS 125C.0035(1) makes the child's best
interest the court's sole consideration in an action determining physical
custody, so a prenup cannot conclusively decide that issue.

Post-marriage changes require a signed writing

After marriage, NRS 123A.070 permits amendment or revocation only through a
written agreement signed by both parties. The amendment or revocation is
enforceable without consideration.

Chapter 123A does not add a new notary, witness, or payment requirement for the
change agreement.

What trips people up

Nevada's unconscionability route stands alone. NRS 123A.080 uses separate
paragraphs for execution-time unconscionability and the three-part disclosure
failure.

The public-assistance rule is narrow. It allows only enough support to avoid
the eligibility caused by the support term; it is not a general second look at
every support bargain.

A disclosure waiver is allowed, but it must be written. Adequate knowledge
is a separate alternative within the same three-part defense.

Common questions

What happens if the marriage is void?

Under NRS 123A.090-123A.100, a void marriage limits enforcement to what is
necessary to avoid an inequitable result. The neighboring section also tolls an
applicable limitations period during marriage while preserving laches and
estoppel.

Can the agreement cover income earned during marriage?

Chapter 123A's property definition expressly includes income and earnings, and
NRS 123A.050 permits terms addressing present or future property rights and
management.

Can a Nevada prenup waive alimony?

It may modify or eliminate alimony, subject to the agreement-wide enforcement
rules and the public-assistance override in NRS 123A.080(2).
