Prenuptial Agreement Requirements in Nevada
At a glance
| Governing law and framework | Nevada Uniform Premarital Agreement Act, NRS ch. 123A; current official text remains the 1989 enactment |
|---|---|
| Writing, signature, and effect | Writing signed by both; enforceable without consideration; effective upon marriage (NRS 123A.040, 123A.060) |
| Execution formalities | No notary, acknowledgment, witness, attestation, oath, or recording requirement in ch. 123A; the statutory form is the signed writing (NRS 123A.040) |
| Financial disclosure and waiver | Fair/reasonable disclosure; voluntary express written waiver or actual/reasonably available adequate knowledge can defeat the three-part disclosure challenge (NRS 123A.080(1)(c)) |
| Independent counsel and timing | No statutory separate-counsel mandate, counsel waiver, final-draft review period, or pre-wedding countdown; voluntary execution remains independently required (NRS 123A.080(1)(a)) |
| Fairness standard and source | Statute — involuntary execution, execution-time unconscionability, or all three disclosure failures independently defeats enforcement; court decides unconscionability as law (NRS 123A.080) |
| Spousal-support limits | May modify or eliminate alimony/support, but the court may order enough support to avoid resulting public-assistance eligibility (NRS 123A.050(1)(d), 123A.080(2)) |
| Child and public-policy limits | Cannot adversely affect child support; personal terms cannot violate public policy or criminal law, and physical custody remains a court best-interests decision (NRS 123A.050, 125C.0035) |
| Amendment and revocation | After marriage, only by a writing signed by both parties; amendment or revocation needs no consideration (NRS 123A.070) |
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).
