S.C. Code Ann. § 15-36-100 – Complaint in actions for damages alleging professional negligence; contemporaneous affidavit of expert specifying negligent act or omission

(A) As used in this section, "expert witness" means an expert who is qualified as to the acceptable conduct of the professional whose conduct is at issue and who:
1. (1) is licensed by an appropriate regulatory agency to practice his or her profession in the location in which the expert practices or teaches; and
2. (2)
  1. (a) is board certified by a national or international association or academy which administers written and oral examinations for certification in the area of practice or specialty about which the opinion on the standard of care is offered; or
  2. (b) has actual professional knowledge and experience in the area of practice or specialty in which the opinion is to be given as the result of having been regularly engaged in:
    1. (i) the active practice of the area of specialty of his or her profession for at least three of the last five years immediately preceding the opinion;
    2. (ii) the teaching of the area of practice or specialty of his or her profession for at least half of his or her professional time as an employed member of the faculty of an educational institution which is accredited in the teaching of his or her profession for at least three of the last five years immediately preceding the opinion; or
    3. (iii) any combination of the active practice or the teaching of his or her profession in a manner which meets the requirements of subitems (i) and (ii) for at least three of the last five years immediately preceding the opinion;
3. (3) is an individual not covered by subsections (A)(1) or (2), that has scientific, technical, or other specialized knowledge which may assist the trier of fact in understanding the evidence and determining a fact or issue in the case, by reason of the individual's study, experience, or both. However, an affidavit filed pursuant to subsection (B) by an expert qualified under this subsection must contain an explanation of the expert's credentials and why the expert is qualified to conduct the review required by subsection (B). The defendant is entitled to challenge the sufficiency of the expert's credentials pursuant to subsection (E).
(B) Except as provided in Section 15-79-125, in an action for damages alleging professional negligence against a professional licensed by or registered with the State of South Carolina and listed in subsection (G) or against any licensed health care facility alleged to be liable based upon the action or inaction of a health care professional licensed by the State of South Carolina and listed in subsection (G), the plaintiff must file as part of the complaint an affidavit of an expert witness which must specify at least one negligent act or omission claimed to exist and the factual basis for each claim based on the available evidence at the time of the filing of the affidavit.
(C)
1. (1) The contemporaneous filing requirement of subsection (B) does not apply to any case in which the period of limitation will expire, or there is a good faith basis to believe it will expire on a claim stated in the complaint, within ten days of the date of filing and, because of the time constraints, the plaintiff alleges that an affidavit of an expert could not be prepared. In such a case, the plaintiff has forty-five days after the filing of the complaint to supplement the pleadings with the affidavit. Upon motion, the trial court, after hearing and for good cause, may extend the time as the court determines justice requires. If an affidavit is not filed within the period specified in this subsection or as extended by the trial court and the defendant against whom an affidavit should have been filed alleges, by motion to dismiss filed contemporaneously with its initial responsive pleading that the plaintiff has failed to file the requisite affidavit, the complaint is subject to dismissal for failure to state a claim. The filing of a motion to dismiss pursuant to this section, shall alter the period for filing an answer to the complaint in accordance with Rule 12(a), South Carolina Rules of Civil Procedure.
2. (2) The contemporaneous filing requirement of subsection (B) is not required to support a pleaded specification of negligence involving subject matter that lies within the ambit of common knowledge and experience, so that no special learning is needed to evaluate the conduct of the defendant.
(D) This section does not extend an applicable period of limitation, except that, if the affidavit is filed within the period specified in this section, the filing of the affidavit after the expiration of the statute of limitations is considered timely and provides no basis for a statute of limitations defense.
(E) If a plaintiff files an affidavit which is allegedly defective, and the defendant to whom it pertains alleges, with specificity, by motion to dismiss filed contemporaneously with its initial responsive pleading, that the affidavit is defective, the plaintiff's complaint is subject to dismissal for failure to state a claim, except that the plaintiff may cure the alleged defect by amendment within thirty days of service of the motion alleging that the affidavit is defective. The trial court may, in the exercise of its discretion, extend the time for filing an amendment or response to the motion, or both, as the trial court determines justice requires. The filing of a motion to dismiss pursuant to this section shall alter the period for filing an answer to the complaint in accordance with Rule 12(a), South Carolina Rules of Civil Procedure.
(F) If a plaintiff fails to file an affidavit as required by this section, and the defendant raises the failure to file an affidavit by motion to dismiss filed contemporaneously with its initial responsive pleading, the complaint is not subject to renewal after the expiration of the applicable period of limitation unless a court determines that the plaintiff had the requisite affidavit within the time required pursuant to this section and the failure to file the affidavit is the result of a mistake. The filing of a motion to dismiss pursuant to this section shall alter the period for filing an answer to the complaint in accordance with Rule 12(a), South Carolina Rules of Civil Procedure.
(G) This section applies to the following professions:
1. (1) architects;
2. (2) attorneys at law;
