South Carolina law states that before an actual lawsuit is filed, a Notice of Intent to File Suit and expert affidavit must be submitted to court beforehand. In that affidavit, a professional must attest to at least one (1) act of medical negligence as described in South Carolina Code of Laws section 15-36-100. If the case is taken to trial, that expert will often be called to validate their affidavit and the information they included.
