S.C. Code Ann. § 62-3-611
(b) Cause for removal exists when removal would be in the best interests of the estate, or if it is shown that a personal representative or the person seeking his appointment intentionally misrepresented material facts in the proceedings leading to his appointment, or that the personal representative has disregarded an order of the court, has become incapable of discharging the duties of his office, or has mismanaged the estate or failed to perform any duty pertaining to the office. Unless the decedent's will directs otherwise, a personal representative appointed at the decedent's domicile, incident to securing appointment of himself or his nominee as ancillary personal representative, may obtain removal of another who was appointed personal representative in this State to administer local assets.
