If you inherit money is your wife entitled to anything?

In Nevada, short answer is "no" -so long as the property is maintained in a separate account and not commingled; inheritances are part of the definition of "separate property" under the statute

An inheritance in Nevada is considered separate property, but the trick is keeping it that way. If any funds are deposited into a joint account, or an account to which your spouse has access, then those funds become community property subject to division in a legal separation or divorce. If anything is purchased in the name of both parties (such as a home or vehicle), it becomes part of the community. If anything is purchased that is used by the household (such as furniture, appliances, or electronics), those items become part of the community. If you anticipate receiving a large inheritance that you wish to preserve as your separate property, you need to consult with an attorney knowledgeable about both family law and estate planning matters.
