Before filing a medical malpractice lawsuit in South Carolina, a claimant must complete specific pre-suit requirements. This typically includes filing a Notice of Intent to File Suit and participating in a pre-suit mediation process. The claim must also be supported by an affidavit from a qualified medical expert who can identify at least one negligent act or omission that breached the professional standard of care. These steps are mandatory and must be completed properly before a lawsuit can move forward in court.
