1. STATUTORY THRESHOLD AND FILING MECHANICS

1.1. Source statutes. The affidavit requirement arises from two interlocking statutes:

• § 15-36-100 — generally requires an expert affidavit in any action for damages alleging professional negligence against a South Carolina-licensed professional.
• § 15-79-125 — for medical malpractice specifically, requires the affidavit to be filed contemporaneously with the Notice of Intent to File Suit, before any civil action may be initiated.

1.2. What "contemporaneous" means. The affidavit must be filed at the same time as the NOI — not after, not pending receipt. There is no statutory grace period.

1.3. Effect of non-filing. Without a compliant affidavit, the eventual complaint is subject to a motion to dismiss for failure to state a claim. Plaintiff has 30 days from service of the motion to amend; failure to cure within that window results in dismissal.

1.4. Common-knowledge exception (§ 15-36-100(C)(2)). Affidavit is not required where the alleged negligence "lies within the ambit of common knowledge and experience." Courts apply this narrowly. Examples that have qualified or are likely to qualify:

• ☐ Surgical instrument or sponge retained inside the patient
• ☐ Wrong-site or wrong-patient surgery
• ☐ Operation on the wrong limb
• ☐ Burn injury caused by improperly grounded electrosurgical equipment

1.5. Filing checklist.

• ☐ Affidavit drafted and reviewed by counsel
• ☐ Expert credentials documented (CV attached as exhibit)
• ☐ Records reviewed list incorporated into the affidavit
• ☐ At least one specific negligent act/omission alleged
• ☐ Factual basis for each claim tied to records
• ☐ Causation language tying breach to injury
• ☐ Expert sworn under oath before notary
• ☐ Original affidavit filed contemporaneously with NOI
• ☐ Service copy attached to NOI served on each defendant

2. EXPERT VETTING AND QUALIFICATION CHECKLIST

2.1. Specialty match (preferred). The expert practices in the same specialty as the defendant provider — e.g., emergency medicine vs. emergency medicine, OB-GYN vs. OB-GYN.

2.2. Related-field sufficiency (Brouwer). Where exact specialty match is impractical, an expert from a related field may suffice if the expert demonstrates:

• ☐ Substantive knowledge of the standard of care applicable to defendant's specialty;
• ☐ Recent clinical, teaching, or research experience that overlaps with the procedure or condition at issue;
• ☐ Familiarity with relevant professional society guidelines and literature.

2.3. Documented qualification factors:

• ☐ Active licensure (state and dates)
• ☐ Board certification(s) and dates
• ☐ Years in clinical practice
• ☐ Hospital privileges (current and within 5 years)
• ☐ Academic appointments (if any)
• ☐ Publications relevant to the subject
• ☐ Continuing medical education (CME) within last 24 months
• ☐ Prior expert work (% plaintiff vs. defense; for impeachment defense)

2.4. Disqualifiers / red flags:

• ☐ Loss of licensure, suspension, or disciplinary action (any state)
• ☐ Practicing outside the specialty for > 5 years
• ☐ Sole practice as a "professional witness" with no current clinical work
• ☐ Conflict of interest with any defendant or institution
• ☐ Prior testimony contradicting the present opinion

3. REQUIRED AFFIDAVIT CONTENT — § 15-36-100(B)

3.1. Mandatory elements. The affidavit MUST set forth:

3.2. Recommended additions (best-practice, not strictly required):

• ☐ Causation statement linking breach to injury (strengthens motion-to-dismiss defense)
• ☐ List of records and materials reviewed
• ☐ Reference to applicable professional-society guidelines
• ☐ Disclosure of compensation arrangements (preempts cross-examination)
• ☐ Explicit statement that the expert is willing to testify at trial if needed

4. RECORDS AND MATERIALS REVIEWED

4.1. The affidavit must be grounded in records, not speculation. Expert review should include at minimum:

• ☐ Complete defendant institution chart for the encounter(s) at issue
• ☐ Defendant physician's office notes (3 years pre/post incident as relevant)
• ☐ Imaging studies (DICOM) and reports
• ☐ Lab and pathology reports
• ☐ Pharmacy and medication-administration records
• ☐ Discharge summaries
• ☐ Subsequent treating-provider records (showing injury manifestation)
• ☐ Autopsy report (if applicable)
• ☐ Hospital policies and procedures in effect on date of incident
• ☐ Relevant peer-reviewed literature and clinical guidelines

4.2. Documentation of review. The expert should retain dated reading notes; the affidavit should list reviewed materials by category and date.

5. STANDARD OF CARE STATEMENT

5.1. Define the relevant standard. The expert must articulate the standard of care applicable to the defendant's specialty in similar circumstances. Sample language:

"The standard of care for a board-certified emergency medicine physician evaluating a patient who presents with a witnessed loss of consciousness, a Glasgow Coma Scale of 12, and a mechanism consistent with traumatic brain injury, is to obtain a non-contrast head CT prior to discharge, in accordance with the New Orleans Criteria and the Canadian CT Head Rule, which are widely accepted decision tools in emergency medicine."

5.2. Tie the standard to authority. Where possible, cite:

• ☐ Professional society guidelines (e.g., ACEP, AAOS, ACOG, ASA)
• ☐ Peer-reviewed clinical decision rules
• ☐ Hospital protocols (if obtained)
• ☐ Textbook authority

6. BREACH / NEGLIGENT ACTS AND OMISSIONS

6.1. Specify each act/omission. Use enumerated paragraphs. Each entry should identify:

6.2. Avoid conclusory statements. "Defendant was negligent" is insufficient. Each line must tie to a specific decision point, a specific record entry, and a specific standard.

7. CAUSATION STATEMENT

7.1. Link breach to injury. Although § 15-36-100 technically requires only the act and the factual basis, including a causation statement greatly reduces motion-to-dismiss exposure. Sample:

"Had Defendant Dr. X obtained the indicated head CT prior to discharge, the developing epidural hematoma would have been detected at a stage when neurosurgical evacuation could have been performed without permanent neurologic deficit. The delay of approximately 14 hours, occasioned by the failure to image, is the direct and proximate cause of the patient's persistent right-sided hemiparesis and aphasia."

7.2. Express in terms of medical probability. Use "to a reasonable degree of medical certainty" or "more likely than not" rather than possibilistic language.

8. DAMAGES AND INJURY STATEMENT

8.1. Identify the injury types the expert is competent to opine on:

• ☐ Permanent physical injury / disability
• ☐ Pain and suffering (medical confirmation of pain-generating pathology)
• ☐ Mental anguish / emotional distress with medical substrate
• ☐ Loss of bodily function or organ
• ☐ Cognitive deficit
• ☐ Premature death (cause-of-death opinion)
• ☐ Need for ongoing or future care (life-care plan)

8.2. Reserve life-care planning to qualified specialists. Treating physicians can opine on prognosis; certified life-care planners or physiatrists are typically retained for life-care plans.

9. EXPERT COMPENSATION AND LITIGATION HISTORY

9.1. Disclose compensation. Sample paragraph:

"I am being compensated at the rate of $[___] per hour for record review, $[___] per hour for deposition testimony, and $[___] per day for trial testimony. My compensation is not contingent on the outcome of this matter."

9.2. Disclose litigation history. Sample paragraph:

"Within the last four years, I have provided expert witness services in approximately [___] medical malpractice matters: approximately [___]% on behalf of plaintiffs and approximately [___]% on behalf of defendants. A list of cases in which I have testified by deposition or at trial within the last four years is appended as Exhibit 2 (per Rule 26(b)(4), SCRCP)."

11. COUNSEL'S FILING COVER MEMORANDUM

[CAPTION]

MEMORANDUM IN SUPPORT OF AFFIDAVIT OF EXPERT WITNESS

TO: Clerk of Court, [COUNTY] County Court of Common Pleas
FROM: [ATTORNEY NAME], counsel for Claimant
DATE: [DATE]
RE: [CIVIL ACTION NO.]

Pursuant to S.C. Code Ann. §§ 15-36-100 and 15-79-125, Claimant contemporaneously files herewith with the Notice of Intent to File Suit:

1. Affidavit of Expert Witness, sworn by [EXPERT NAME], [CREDENTIALS], dated [DATE];
2. Exhibit 1 — Expert's Curriculum Vitae;
3. Exhibit 2 — Expert's testimony history;
4. Exhibit 3 — Records-reviewed schedule.

The affidavit identifies at least one specific negligent act or omission by each named Defendant and the factual basis for each claim, and is grounded in records identified in the attached schedule. The expert is qualified by board certification, active clinical practice, and substantive familiarity with the applicable standard of care.

[SIGNATURE BLOCK]

12. CURING A DEFECTIVE AFFIDAVIT

12.1. Defendant's challenge mechanism (§ 15-36-100(E)). A defendant may move to dismiss for a defective affidavit, but only contemporaneously with the initial responsive pleading. Late challenges are waived.

12.2. Cure window. Plaintiff has 30 days from service of the motion to amend. Amendment may include:

• ☐ Substituting a more qualified expert
• ☐ Adding factual detail tying acts to records
• ☐ Adding a causation paragraph
• ☐ Correcting credential errors
• ☐ Adding the "reasoning explaining qualification" required by § 15-36-100(D)

12.3. Cure checklist:

• ☐ Identify the specific defect alleged in defendant's motion
• ☐ Confer with original expert; assess feasibility of cure
• ☐ If original expert unavailable or unsuitable, retain replacement within 14 days
• ☐ Draft amended affidavit; verify all § 15-36-100(B) and (D) elements
• ☐ File amended affidavit within 30 days; serve on all parties
• ☐ Consider seeking court extension of cure window for good cause

12.4. Strategic note. A second defective affidavit may not be entitled to a further 30-day cure. Get the cure right the first time.

13. COMMON-KNOWLEDGE EXCEPTION MEMO

13.1. Statutory text (§ 15-36-100(C)(2)). The contemporaneous filing requirement "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."

13.2. When to invoke. Reserve for cases where the negligence is so obvious that any layperson can recognize it without medical training:

• ☐ Surgical sponge or instrument retained in body cavity
• ☐ Wrong-site or wrong-patient surgery
• ☐ Operation on the wrong limb
• ☐ Failure to monitor an obviously deteriorating patient
• ☐ Burns from improperly grounded equipment
• ☐ Patient falls from unattended gurney with raised siderails missing

13.3. Best practice. Even when invoking the exception, file a protective affidavit to prevent dismissal if the court rejects the common-knowledge characterization. The cost of the affidavit is far less than the cost of dismissal and refiling.

13.4. Notice in pleading. When invoking the exception, the NOI should expressly state: "Pursuant to S.C. Code Ann. § 15-36-100(C)(2), the negligence pleaded herein lies within the ambit of common knowledge and experience and does not require an expert affidavit. In the alternative, an expert affidavit is filed contemporaneously herewith."

14. MULTI-DEFENDANT AFFIDAVIT STRATEGY

14.1. Coverage requirement. Each named defendant must be supported by an expert qualified to opine on that defendant's standard of care. A single affiant may cover multiple defendants if qualified across specialties; otherwise, multiple affidavits are needed.

14.2. Qualification matrix:

14.3. Avoid the "all-purpose expert" trap. Courts disfavor a single physician opining outside their specialty. Use the related-field doctrine selectively and document overlap explicitly.

14.4. Hospital-as-defendant. Where corporate or systemic negligence is alleged (negligent credentialing, failure to enforce policies, inadequate staffing), an institutional/risk-management expert with hospital administration credentials is preferred.

15. SOUTH CAROLINA PRACTICE NOTES

15.1. No counsel-only certifications. Unlike some jurisdictions (e.g., Pennsylvania's certificate of merit), South Carolina requires a sworn expert affidavit. Counsel cannot self-certify.

15.2. Brouwer / Ranucci line of authority. The South Carolina Supreme Court has clarified (Brouwer, 2014; Ranucci, 2014) that the affidavit need not match specialty exactly; substantive qualification controls. Document overlap with care.

15.3. Apology Statute interplay (§ 19-1-190). Apologetic statements by providers during designated meetings are inadmissible. Do not predicate the factual basis on such statements; build the affidavit on chart entries, lab values, imaging, and policies.

15.4. Damages cap (§ 15-32-220). Note for client-counseling: noneconomic damages are capped (2026 indexed: ~$580,461 single provider / ~$1,741,383 aggregate; verify via S.C. RFA Office). The cap does not apply to economic damages or to grossly negligent / willful / wanton / reckless / intoxication-related conduct (§ 15-32-220(F)). An expert opinion that defendant's conduct met the gross-negligence threshold may be valuable for cap-removal purposes; consider including such language where the facts support it.

15.5. Joint and several liability (§ 15-38-15). Allocation among multiple defendants matters: a defendant <50% at fault is severally (not jointly and severally) liable. Affidavits supporting fault apportionment ≥ 50% against a deep-pocket defendant strengthen recovery.

15.6. Statute of limitations / repose (§ 15-3-545). Filing the NOI (with affidavit) tolls the SOL, but the 6-year repose is a hard ceiling that is generally not tolled by the NOI. Calendar accordingly.

15.7. Peer-review privilege (§ 40-71-20). Hospital quality / morbidity-and-mortality records are largely protected. Expert opinions should not rely on documents subject to the privilege; instead, build on the patient chart, policies, and external standards.

15.8. Daubert / Rule 702 (SCRE). Although the affidavit is filed pre-suit, opinions should be defensible under Rule 702 SCRE — based on sufficient facts/data, reliable principles, and applied reliably. State v. Council, 335 S.C. 1, 515 S.E.2d 508 (1999), and successors govern admissibility.

15.9. Wrongful death and survival. For § 15-51-10 et seq. wrongful-death claims, the affidavit must include a cause-of-death opinion to a reasonable degree of medical certainty. Consider engaging both a treating physician and a forensic pathologist where causation is contested.
