Modification of custody: establishing impact of change on welfare of child

G.S. 50-13.7(a) provides that “… an order … for the custody of a minor child may be modified or vacated at any time, upon motion in the cause and a showing of changed circumstances by either party or anyone interested.” However, case law supplements this statute to provide that an order may be modified only upon a showing of a substantial change in circumstances since the entry of the original order, Savani v. Savani, 102 NC App 496 (2001), and the substantial change must affect the welfare of the minor child. Pulliam v. Smith, 348 NC 616 (1998); Shipman v. Shipman, 357 NC 471 (2003).
