Indiana code § 1-1-2-1 provides:
Sec. 1. The law governing this state is declared to be:
Fourth. The common law of England, and statutes of the British Parliament made in aid thereof prior to the fourth year of the reign of James the First? [FN1] (except the second section of the sixth chapter of forty-third Elizabeth, the eighth chapter of thirteenth Elizabeth, and the ninth chapter of thirty-seventh Henry the Eighth,) and which are of a general nature, not local to that kingdom, and not inconsistent with the first, second and third specifications of this section.
Leone v. COM'R, BUREAU OF MOTOR VEHICLES, 933 NE 2d 1244 - Ind: Supreme Court 2010 provides:
The very nature of a common-law name change means it does not require a court's approval..All states have enacted similar statutes, and all but two have concluded that they do not abrogate but instead supplement the common law.
Statutes obliging citizens to engage in some formality when they invoke government processes by applying for benefits or identification cards neither obliterate common-law usage nor are they driven by them.
