Colorado Revised Statutes § 2-4-211 states:
The common law of England so far as the same is applicable and of a general nature...shall be considered as of full force until repealed by legislative authority.

IN RE APPLICATION OF KNIGHT 537 P.2d 1085 (1975) Colorado Court of Appeals, Div. III. states:
"At common law, a person could adopt another name at will. Statutes setting forth procedures to be followed in changing a name merely provide an additional method for making the change. See 57 Am.Jur.2d Name §§ 10 and 11."
