How to Prove Cohabitation to Terminate Alimony in Nevada

Current as of: October 11, 2026 Alimony & Spousal Support Nevada
Under Nevada law, you can ask a judge to terminate your alimony payments if your ex-spouse is cohabiting with a new partner. However, you must prove that the relationship is romantic and that they share a substantial financial contribution.

Cohabitation Under Nevada Law

Paying alimony to a former spouse is often a frustrating financial burden, but that frustration typically peaks when the paying spouse discovers their ex is living with a new romantic partner. In Nevada, you do not have to pay spousal support indefinitely if your ex has effectively moved on and merged their life with someone else. However, the legal burden of proving this relationship falls entirely on you. If you believe you are paying unnecessary support, browsing our directory of USA Lawyers to find an aggressive Nevada family law attorney is the most effective way to protect your finances.

Under Nev. Rev. Stat. § 125.150, a court must generally terminate spousal support if the receiving spouse remarries. But what if they intentionally avoid getting married just to keep collecting your alimony checks? Nevada law allows you to file a modification request based on 'cohabitation.' Proving cohabitation in courts like the Eighth Judicial District Court, Family Division, Las Vegas or the Ninth Judicial District Court, Minden requires much more than simply showing they share the same address.

Roommate vs Romantic Partner

The first hurdle your lawyer must overcome is proving the relationship is romantic and marriage-like, rather than a simple roommate agreement. If your ex-spouse rents out a spare bedroom to a friend to help cover the mortgage, the court will not terminate your alimony.

To establish that the new person is a romantic partner, your attorney will look for evidence of a shared life. Do they share a bedroom? Do they take vacations together? Do they attend family functions as a couple? Social media posts, photographs, and witness testimonies are heavily utilized to differentiate a roommate from a life partner.

The Financial Contribution Test

Even if you prove the relationship is romantic, it is not enough to automatically terminate support. The Nevada Supreme Court set a strict precedent in the landmark case Gilman v. Gilman, 114 Nev. 416 (NV Supreme Court 1998). The court established the 'financial contribution' test.

To terminate or reduce alimony, you must show that the new cohabitant is either financially supporting your ex-spouse (meaning your ex no longer needs your alimony) or that your ex-spouse is using your alimony money to financially support the new partner (which is a misuse of spousal support). If they keep their finances completely separate and split bills 50/50 like standard roommates, the judge may refuse to terminate the support.

Step-by-Step Process to Terminate Support in NV

Terminating alimony requires building a rock-solid evidentiary case before ever stepping foot in a courtroom.

Step 1: Using Private Investigators

Your ex is unlikely to admit they are cohabiting. The most effective way to prove they live together is by hiring a licensed Nevada private investigator. A P.I. will conduct surveillance to show the new partner's car is parked in the driveway overnight, seven days a week. They can also document the partner doing household chores, retrieving the mail, or using keys to enter the home freely-all classic signs of residency.

Step 2: Shared Bank Accounts as Evidence

Once you file a motion, your attorney will enter the 'discovery' phase. They can legally subpoena your ex-spouse's bank statements, lease agreements, and utility bills. If the records show the new partner is paying half the mortgage, sharing a joint checking account, or paying for your ex's groceries, you have successfully proven the financial intertwining required by the Gilman test.

Step 3: Filing the Legal Motion

Armed with surveillance and financial data, your lawyer will file a Motion to Modify or Terminate Alimony. The court will schedule an evidentiary hearing where your lawyer will present the evidence, cross-examine your ex-spouse, and ask the judge to formally end your payment obligations under Nev. Rev. Stat. § 125.150(8).

Frequently Asked Questions (FAQ)

If I prove cohabitation, do I get a refund for past alimony paid?

Generally, no. Courts typically only modify or terminate alimony moving forward from the date you officially filed the Motion to Modify. This is why it is critical to file the paperwork as soon as you have solid evidence, rather than waiting.

What if my original divorce decree says alimony is non-modifiable?

If you and your ex signed a binding settlement agreement stating that spousal support is strictly non-modifiable regardless of future circumstances, the court generally cannot terminate it, even if they remarry or cohabit. Your lawyer must review the original decree carefully.

Does it count if the new partner only stays over on weekends?

No. Spending a few nights a week together is generally considered 'dating' under Nevada law, not cohabiting. Cohabitation requires a continuous, permanent living arrangement under the same roof.

Can I just stop paying if I know they are living together?

Absolutely not. If you stop paying alimony without a formal court order terminating it, you will be in contempt of court. Your ex-spouse could file a motion to enforce the payments, leading to severe financial penalties and potential wage garnishment.
