Utah Code 68-3-1 provides:
The common law of England so far as it is not repugnant to, or in conflict with, the constitution or laws of the United States, or the constitution or laws of this state, and so far only as it is consistent with and adapted to the natural and physical conditions of this state and the necessities of the people hereof, is hereby adopted, and shall be the rule of decision in all courts of this state.

In re Cruchelow, 926 P. 2d 833 - Utah: Supreme Court 1996 states:
It is generally recognized that statutes similar to sections 42-1-1 and -2, which set forth procedures to be followed in changing one's name, merely provide a codified process to aid an individual's common law right to adopt another name at will. See Isom v. Circuit Court of the Tenth Jud. Circuit, 437 So.2d 732, 733 (Fla.Dist.Ct.App. 1983) (citing 57 Am.Jur.2d Name § 11; In re Application of Knight, 36 Colo.App. 187, 537 P.2d 1085 (1975)).

In re Porter, 31 P. 3d 519 - Utah: Supreme Court 2001 states:
The purpose of these two statutes bears upon our analysis regarding whether proper cause exists to grant a name change. Statutes similar to sections 42-1-1 and-2 are recognized to merely provide a codified process to aid an individual's common law right to adopt another name at will. In re Cruchelow, 926 P.2d at 834; see also In re Knight, 36 Colo.App. 187, 537 P.2d 1085, 1086 (1975); Moskowitz, 385 A.2d at 122. T

Sections 42-1-1 and-2 of the Utah Code "provide a codified process to aid an individual's common law right to adopt another name at will."
