Merger of Custom Law and Legal Definition

Merger of custom refers to the extinguishment of a custom by a statute which deals with the subject matter.

A custom or usage repugnant to the express provisions of a statute is void, and whenever there is a conflict between a custom or usage and a statutory regulation, the statutory regulation must control. [Creekmore v. F. T. Justice & Co., 152 Ky. 514 (Ky. 1913)].
