Modifying Alimony in Nevada (Updated 2026)

⚠️ CRITICAL: Modifications are NOT retroactive. Under NRS 125.150(7), any change applies only from the date you file the motion. Even if you lost your job in January, filing in May means payments due Jan–Apr remain at original amount. File immediately when circumstances change.

Grounds for Modification (NRS 125.210)

A 20% or more change in gross monthly income of the payor shall be deemed changed circumstances requiring review (NRS 125.210(10)).

Remarriage of recipient (automatic termination unless order states otherwise).

Payor's reasonable retirement (typically age 65+).

Recipient's cohabitation in a marriage-like relationship (must petition court).

Exception (Gilman v. Gilman, 114 Nev. 416): If decree says alimony "cannot be modified under any circumstances," court may lack jurisdiction to modify.

Process

File Petition for Modification → Serve Notice → Gather Evidence (pay stubs, tax returns) → Mediation → Court Hearing.

Recent & Key Nevada Alimony Case Law

Rivero v. Rivero (2021)

137 Nev. Adv. Op. 32, 486 P.3d 703

Reaffirmed that alimony is not punitive; courts must focus on need and ability to pay. Clarified that a "substantial change" under NRS 125.150 includes a 20% income reduction as a statutory trigger for review.

Klabacka v. Nelson (2017)

133 Nev. ___, 394 P.3d 940

Alimony is meant to support a spouse lacking sufficient property or ability to be self-supporting; spendthrift trusts do not shield assets from support claims.

Gilman v. Gilman (1998)

114 Nev. 416, 426

If a divorce decree explicitly states alimony "cannot be modified under any circumstances," the court may lack jurisdiction to modify it, regardless of changed circumstances.

Shydler v. Shydler (1998)

114 Nev. 192

Two primary purposes: (1) narrow gaps in earning capacity; (2) allow recipient to live as close as possible to marital standard of living.

Nevada Spousal Alimony FAQs

How is alimony calculated in Nevada? Is there a formula?

No statutory formula. Judges use broad discretion under NRS 125.150. Many attorneys use a guideline of ~33% of payer's net minus 25% of recipient's net as a starting negotiation point.

NRS 125.150

What is the 20% modification rule?

Under NRS 125.210(10), a change of 20% or more in the payor's gross monthly income is deemed changed circumstances requiring review for modification. Modifications are not retroactive — effective only from filing date.

NRS 125.210(10); Rivero v. Rivero (2021)

Does domestic violence affect alimony?

Nevada is no-fault; domestic violence is not a direct statutory factor under NRS 125.150. However, financial waste or mental health impacts on earning capacity may be considered indirectly.

Can alimony be modified if I retire?

Yes. Retirement at a reasonable age (typically 65+) is a substantial change. The court will examine if retirement is bona fide and the payor's retirement income (pension, Social Security).

What happens if the recipient cohabitates?

Cohabitation alone does not automatically terminate alimony. The payor must petition the court and prove a marriage-like relationship with financial interdependence. Remarriage automatically terminates alimony.
