Nevada calculates child support based on a percentage of the non-custodial parent's gross monthly income under NRS 125B.070 and NAC Chapter 425. The base percentages for income up to $6,000/month are 16% for one child, 22% for two, 26% for three, and an additional 2% per child thereafter. A tiered system applies graduated lower percentages to higher income brackets. In joint custody arrangements, support is calculated for both parents and the higher earner pays the difference.

A postnuptial agreement in Nevada is a legally binding contract signed after marriage that governs property division in the event of divorce or death. Under NRS 123.070, Nevada permits married couples to enter into property contracts subject to fiduciary duties, requiring written execution, full financial disclosure, and voluntary consent from both spouses. Unlike prenuptial agreements governed by the Uniform Premarital Agreement Act (NRS Chapter 123A), postnuptial agreements in Nevada face heightened court scrutiny because spouses owe each other fiduciary obligations. Nevada courts enforce postnuptial agreements that address property division but will not enforce provisions attempting to waive future spousal support under NRS 123.080.

What Is a Postnuptial Agreement Under Nevada Law

A postnuptial agreement is a contract executed after marriage that defines how spouses will divide property, debts, and financial assets if the marriage ends through divorce or death. Under NRS 123.070, either spouse may enter into any property contract with the other spouse, subject to the fiduciary duties that govern relationships of confidence and trust. Nevada courts distinguish postnuptial agreements from prenuptial agreements because married spouses already owe each other heightened duties of disclosure and fair dealing that do not exist between engaged couples.

The scope of what a postnuptial agreement may accomplish in Nevada is more limited than a prenuptial agreement. Under NRS 123.080, married couples cannot alter their legal relations except as to property, meaning postnuptial agreements can address asset division but cannot waive future spousal support obligations. This stands in contrast to prenuptial agreements, which may include enforceable alimony waivers under the Uniform Premarital Agreement Act codified in NRS Chapter 123A.

Common reasons Nevada couples execute postnuptial agreements include protecting a family business valued at $500,000 or more, clarifying ownership of inherited assets, addressing financial infidelity that created $50,000 or more in undisclosed debt, planning for blended family estate distribution, and converting separate property to community property for tax planning purposes. Business owners frequently use postnuptial agreements to ensure that a closely held company remains with the founding spouse rather than becoming subject to community property division.

Legal Requirements for a Valid Nevada Postnuptial Agreement

Nevada law establishes five mandatory requirements for an enforceable postnuptial agreement: written form, voluntary execution, full financial disclosure, absence of unconscionability, and compliance with public policy. Failure to satisfy any requirement may render the entire agreement void or voidable.

The written requirement under NRS 123.270 mandates that all marriage contracts must be in writing and executed and acknowledged in the same manner as a conveyance of land. This means both spouses must sign before a notary public, and the signatures must be properly acknowledged. Oral agreements between spouses regarding property division are not enforceable in Nevada courts.

Voluntary execution requires that both spouses sign willingly without coercion, duress, or undue influence. Because married couples occupy a confidential relationship under Nevada law, courts presume that one spouse may exercise influence over the other. Signs of involuntary execution include presenting the agreement immediately before a major financial transaction, threatening divorce unless the other spouse signs, or giving less than 7-14 days to review the document with independent counsel.

Full financial disclosure is absolutely non-negotiable in Nevada postnuptial agreements. Both spouses must provide complete and honest disclosure of all assets, debts, income sources, and business interests before signing. Hiding a single asset worth as little as $5,000 can void the entire agreement. Nevada courts apply the fiduciary standard from NRS 123.070, which requires the general rules that control the actions of persons occupying relations of confidence and trust toward each other.

The unconscionability standard evaluates whether the agreement was grossly unfair at the time of execution. Under NRS 123A.080 (applied by analogy to postnuptial agreements), an agreement is unenforceable if it was unconscionable when signed and there was inadequate disclosure. Courts consider factors including whether one spouse waived substantially all property rights without receiving anything in return, whether the terms shock the conscience of a reasonable person, and whether one spouse was left destitute while the other retained millions in assets.

What Nevada Postnuptial Agreements Can and Cannot Include

Nevada postnuptial agreements can address all property-related matters between spouses but face strict limitations on non-property issues. Understanding these boundaries prevents wasted legal fees on unenforceable provisions and ensures the entire agreement remains valid.

Permitted provisions in Nevada postnuptial agreements include characterization of existing assets as separate or community property, division of future income and business profits, allocation of debt responsibility (including credit cards, mortgages, and student loans), distribution of retirement accounts and pensions, life insurance beneficiary designations, real estate ownership and distribution, business interest valuations and buyout provisions, and inheritance rights modifications.

Prohibited provisions under NRS 123.080 include waiver of future alimony or spousal support, child custody arrangements, child support modifications, and any terms that violate public policy. The Nevada Supreme Court has consistently held that spouses cannot limit their support obligations to each other through a postnuptial agreement—such limitations are only permitted in prenuptial agreements executed before the marriage begins.

The alimony restriction deserves special attention because it represents the most significant difference between Nevada prenuptial and postnuptial agreements. A prenuptial agreement executed before marriage may include an enforceable alimony waiver under NRS 123A.080. However, the identical provision in a postnuptial agreement signed one day after the wedding ceremony would be unenforceable under NRS 123.080. This distinction leads some Nevada attorneys to recommend that couples who failed to execute a prenuptial agreement consider a brief legal separation followed by reconciliation with a new prenuptial agreement.

Heightened Scrutiny Standard for Nevada Postnuptial Agreements

Nevada courts scrutinize postnuptial agreements more heavily than prenuptial agreements because married spouses owe fiduciary duties to each other that do not exist between engaged couples. The Nevada Supreme Court has established that spouses occupy a confidential relationship requiring good faith, fair dealing, and complete honesty in all financial matters.

The presumption of fraud doctrine applies when a postnuptial agreement greatly favors one spouse over the other. Under Nevada case law including Fick v. Fick, Sogg v. Nevada State Bank, and Kantor v. Kantor, courts presume that unequal agreements resulted from undue influence unless the disadvantaged spouse proves otherwise. This shifts the burden of proof—the spouse seeking to enforce the agreement must demonstrate that adequate disclosure occurred and that the other spouse understood the consequences of signing.

Independent legal counsel for both spouses is essential to establishing enforceability. While Nevada law does not technically require independent attorneys, courts view separate representation as strong evidence that both parties entered the agreement with full knowledge of their rights. When one spouse retains the attorney who drafted the agreement while the other spouse has no counsel, courts frequently find that the unrepresented spouse did not have a meaningful opportunity to understand the document.

Practical recommendations for ensuring enforceability include engaging separate attorneys for each spouse (budget $1,500-$3,000 per spouse for attorney fees), exchanging comprehensive financial disclosures at least 30 days before signing, scheduling the execution date at least 2-3 weeks after the final draft to demonstrate absence of coercion, video recording the signing ceremony to document voluntary execution, and attaching all financial disclosure schedules as exhibits to the agreement.

Postnuptial Agreements and Nevada Community Property Law

Nevada is one of nine community property states, meaning that without a valid agreement, all assets acquired during marriage are owned equally by both spouses and divided 50/50 upon divorce. Under NRS 125.150, Nevada courts must make an equal disposition of community property to the extent practicable, with limited exceptions for compelling circumstances like marital waste.

A postnuptial agreement allows spouses to opt out of default community property rules by converting community property to separate property (or vice versa), agreeing to unequal division percentages, protecting future inheritances from community property claims, and clarifying the character of mixed or commingled assets. For example, spouses might agree that a husband's technology startup remains his separate property even though he worked on it during the marriage using marital time and resources.

The recording requirement under NRS 123.280 mandates that postnuptial agreements affecting real property must be recorded in the office of the recorder of every county in which any real property is situated. Failure to record does not invalidate the agreement between the spouses, but it may affect the agreement's enforceability against third parties such as creditors or subsequent purchasers.

Joint tenancy property requires special consideration. Under NRS 125.150(2), Nevada courts dispose of joint tenancy property in the same manner as community property, with a presumption of equal division. However, if one spouse contributed separate property funds toward acquiring jointly held property, the court may provide reimbursement. A postnuptial agreement can clarify these contributions and avoid disputes over tracing and reimbursement.

Modifying or Revoking a Nevada Postnuptial Agreement

Nevada law permits spouses to modify or revoke a postnuptial agreement at any time through mutual written consent. The modification or revocation must satisfy the same formality requirements as the original agreement—it must be in writing, signed by both parties, and acknowledged before a notary public.

Common reasons for modification include significant changes in financial circumstances (such as one spouse receiving a $1 million inheritance), the birth of children, career changes affecting earning capacity, acquisition of new business interests, and relocation to another state with different marital property laws. The modification should specifically reference the original agreement, identify the sections being changed, and include updated financial disclosures.

Revocation may be express (through a written document stating the agreement is void) or implied (through conduct inconsistent with the agreement's terms). However, implied revocation creates litigation risk because courts must determine whether both spouses intended to abandon the agreement. The safer approach is always express written revocation with notarized signatures from both parties.

Statute of limitations considerations apply when challenging a postnuptial agreement. Under NRS 125.150, a party may file a postjudgment motion to obtain adjudication of any community property or liability omitted from the decree as the result of fraud or mistake within 3 years after discovering the fraud or mistake. This means that undisclosed assets hidden during the postnuptial agreement process may be challenged years after the divorce is finalized.

Enforcement During Nevada Divorce Proceedings

When spouses with a postnuptial agreement file for divorce in Nevada, the court must determine whether to enforce the agreement or set it aside. The divorce filing fee ranges from $326 in Washoe County to $364 in Clark County as of March 2026, plus $50-125 for process service if filing without an attorney.

Nevada's residency requirement under NRS 125.020 requires at least one spouse to have resided in the state for a minimum of 6 consecutive weeks before filing. This is one of the shortest residency requirements in the United States. The filing spouse must provide an Affidavit of Resident Witness signed by another Nevada resident who can confirm physical presence in the state.

The spouse seeking to enforce the agreement bears the burden of proving validity. The challenging spouse may raise defenses including lack of full financial disclosure at the time of signing, coercion or duress in obtaining signature, unconscionability of terms when executed, inclusion of prohibited provisions (alimony waiver, child custody terms), and failure to meet writing and acknowledgment requirements.

If the court finds the postnuptial agreement valid, it will generally enforce the property division terms as written. If the court finds the agreement invalid in part, it may sever the unenforceable provisions and enforce the remainder (if the agreement includes a severability clause) or invalidate the entire agreement (if no severability clause exists or if the invalid provisions are central to the agreement's purpose).

Cost and Timeline for Nevada Postnuptial Agreements

The total cost of a properly drafted and executed postnuptial agreement in Nevada typically ranges from $3,000 to $15,000, depending on complexity. Simple agreements addressing a few assets may cost $3,000-$5,000, while complex agreements involving multiple businesses, trusts, and real estate holdings may cost $10,000-$15,000 or more.

Cost breakdown typically includes attorney fees for the drafting spouse ($1,500-$5,000), attorney fees for the reviewing spouse ($1,500-$3,000), financial disclosure preparation ($500-$2,000 if accountant involvement needed), notary and execution costs ($50-$150), and recording fees if real property affected ($50-$100 per county).

The recommended timeline from initial consultation to execution is 60-90 days. This allows 1-2 weeks for initial attorney consultations and engagement, 2-3 weeks for financial disclosure compilation, 2-3 weeks for initial draft preparation, 2-3 weeks for review and negotiation, and 1-2 weeks cooling off period before signing. Rushing the process increases the risk that a court will later find the agreement was signed under duress.

How much does a postnuptial agreement cost in Nevada?

A Nevada postnuptial agreement typically costs $3,000 to $15,000 total, including attorney fees for both spouses. Simple agreements addressing limited assets cost $3,000-$5,000, while complex agreements involving businesses, trusts, and multiple properties cost $10,000-$15,000 or more. Each spouse should budget $1,500-$5,000 for independent legal representation to ensure the agreement withstands court scrutiny.

What makes a postnuptial agreement invalid in Nevada?

Nevada courts invalidate postnuptial agreements for lack of written form, involuntary execution (coercion or duress), failure to provide full financial disclosure, unconscionable terms at execution, inclusion of prohibited provisions (alimony waiver, child custody predetermination), and violation of public policy. Hiding assets worth as little as $5,000 can void the entire agreement due to the heightened disclosure requirements between spouses.

Do both spouses need lawyers for a Nevada postnuptial agreement?

While Nevada law does not require both spouses to have independent attorneys, courts strongly favor agreements where each spouse received separate legal counsel. When only one spouse has representation, courts frequently find the unrepresented spouse lacked meaningful opportunity to understand their rights. Budget $1,500-$3,000 per spouse for attorney fees to maximize enforceability.

Can a postnuptial agreement protect my business in Nevada?

Yes, a postnuptial agreement can protect a business by characterizing it as separate property, establishing a fixed value for buyout purposes, and preventing claims to future appreciation. Business owners frequently use postnuptial agreements to ensure closely held companies remain with the founding spouse rather than becoming subject to Nevada's 50/50 community property division under NRS 125.150.

How long does it take to create a Nevada postnuptial agreement?

The recommended timeline from initial consultation to execution is 60-90 days. This includes 1-2 weeks for attorney engagement, 2-3 weeks for financial disclosure compilation, 2-3 weeks for drafting, 2-3 weeks for negotiation, and 1-2 weeks cooling off before signing. Rushing the process increases litigation risk—courts may find agreements signed quickly were executed under duress.

Can we modify a postnuptial agreement after signing in Nevada?

Yes, Nevada law permits spouses to modify or revoke a postnuptial agreement at any time through mutual written consent. The modification must be in writing, signed by both parties, and notarized. Common reasons for modification include significant inheritance ($1 million+), birth of children, career changes, and acquisition of new business interests. Updated financial disclosures should accompany any modification.

What happens if we move to another state after signing a Nevada postnuptial agreement?

Nevada postnuptial agreements generally remain enforceable when spouses relocate, but the new state's courts will apply their own enforceability standards. Some states have stricter requirements than Nevada (such as requiring consideration beyond the marriage itself), while others may not enforce certain provisions. Couples should consult attorneys in both states when relocating to determine if modifications are needed.

Does a postnuptial agreement affect child custody or child support in Nevada?

No, postnuptial agreements cannot predetermine child custody or child support in Nevada. Courts retain exclusive jurisdiction over children's welfare and will not enforce contractual provisions that attempt to limit support or restrict custody. Any postnuptial agreement provisions addressing children are unenforceable, and including them may cause courts to question the validity of the entire agreement.
