In the state of Nevada, inheritance money falls under the category of "separate property." It's not subject to asset division during a divorce, unless the spouse who received the inheritance co-mingled it with marital assets. Co-mingling of an inheritance happens when you deposit your inheritance money into a joint marital account, or when you use the money to benefit both you and your spouse or your family.
It's challenging and unclear to determine what part of a co-mingled inheritance is yours and what part belongs to the marital estate. From a logical perspective, this is why Nevada family law courts tend to view co-mingled inheritance money as a part of the marital estate. However, depending on your situation, you might be able to save some of your co-mingled inheritance money.
