Arkansas code 1-2-119 provides:
The common law of England, so far as it is applicable and of a general nature, and all statutes of the British Parliament in aid of or to supply the defects of the common law made prior to March 24, 1606, which are applicable to our own form of government, of a general nature and not local to that kingdom, and not inconsistent with the Constitution and laws of the United States or the Constitution and laws of this state, shall be the rule of decision in this state unless altered or repealed by the General Assembly of this state.

Clinton v. Morrow, 247 SW 2d 1015 - Ark: Supreme Court 1952 states:
The general rule on this question is stated as follows in 38 Am.Jur., Names, § 28: "In the absence of a statute to the contrary, a person may ordinarily change his name at will, without any legal proceedings, merely by adopting another name. He may not do so, however, for fraudulent purposes. In most jurisdictions, a change of one's name is regulated by statutes which prescribe the proceedings by which such change is to be accomplished. These statutes merely affirm, and are in aid of, the common-law rule. They do not repeal the common law by implication or otherwise, but afford an additional method of effecting a change of name."
