NRS 1.030 provides:
The common law of England, so far as it is not repugnant to or in conflict with the Constitution and laws of the United States, or the Constitution and laws of this State, shall be the rule of decision in all the courts of this State.

United States v. McKay, 2 F. 2d 257 - Dist. Court, D. Nevada 1924 further states:
Under the common law a man can change his name at will, provided it is not done with a fraudulent purpose; he may sue and be sued by such adopted name, and will be bound by any contract into which he enters in his adopted name. This is true in the absence of a restrictive statute, and is not abrogated by the fact that a procedure is provided by statute for the change of one's name. 20 Standard Ency. 250; In re McUlta (D. C.) 189 Fed. 250; Linton v. Bank (C. C.) 10 Fed. 894.
