The Pre-Suit Process: Filing a Notice of Intent and Expert Witness Affidavits in South Carolina

Current as of: October 5, 2026 Medical Malpractice South Carolina
Before you can officially sue a doctor for malpractice in South Carolina, state law requires you to file a Notice of Intent to File Suit and complete a mandatory pre-suit mediation. You must also obtain a sworn affidavit from a qualified medical expert verifying that the healthcare provider breached the standard of care.

You cannot simply run down to the local courthouse in South Carolina and sue a doctor for medical malpractice. Because medical lawsuits are incredibly complex and expensive for the state's healthcare system, state lawmakers have built a robust "pre-suit" hurdle. Before a judge will even look at your actual lawsuit, you must navigate a mandatory screening process designed to weed out frivolous claims.

Whether your injury occurred at a large hospital in Columbia or a local clinic in Myrtle Beach, skipping even one of these pre-suit steps will result in your case being immediately dismissed. The process requires filing formal notices, hiring independent medical experts, and sitting down for mediation before the standard litigation process begins.

Step-by-Step Pre-Suit Requirements in South Carolina

The pre-suit process is highly technical and tightly regulated by state statutes. It operates as a distinct phase of legal action that occurs just before the official civil complaint is filed.

Step 1: Filing the Notice of Intent (NOI)

The very first legal step is drafting and filing a Notice of Intent to File Suit. According to S.C. Code Ann. § 15-79-125, you must file this notice in the county where the malpractice occurred, such as the Horry County Court of Common Pleas, Conway. This document is not a standardized state form; it is a formal legal pleading drafted by an attorney warning the medical provider that you intend to sue them. It must detail the patient's identity, the dates of treatment, and a short summary of how the medical care fell below the acceptable standard. You formally initiate this filing alongside a Form SCCA 234, South Carolina, Judicial Branch, Civil Action Coversheet.

Step 2: The Mandatory Expert Witness Affidavit

You cannot simply claim the doctor made a mistake; you must have another doctor back you up. Before filing the NOI, you must comply with S.C. Code Ann. § 15-36-100, which requires an expert witness affidavit. Your lawyer must hire a medical expert who practices in the exact same medical specialty as the doctor you are accusing. This expert must review your medical records, sign a sworn affidavit stating that they believe a negligent act occurred, and specify exactly how the standard of care was breached. While contemporaneous filing is strictly required, the South Carolina Supreme Court clarified in Ranucci v. Crain, 409 S.C. 493 (SC Supreme Court 2014) that S.C. Code Ann. § 15-79-125(A) fully incorporates the statutory 45-day safe-harbor extension under S.C. Code Ann. § 15-36-100(C)(1), reversing the dismissal of a claim where the plaintiff faced an imminent statute of limitations deadline.

Step 3: Mandatory Pre-Suit Mediation

Once the Notice of Intent and the expert affidavit are filed and served on the defendants, the law pauses the clock. Under state statute, the parties must participate in mandatory mediation within 90 to 120 days. Mediation is a formal meeting where a neutral third party (the mediator) tries to help you and the hospital's insurance company reach a financial settlement without going to trial. Both sides are required to attend and negotiate in good faith.

What Happens if Mediation Fails?

If the hospital refuses to offer a fair settlement during the pre-suit mediation, the mediator will declare an impasse. Only after the mediator signs a document stating that mediation has failed are you legally allowed to file your actual Civil Summons and Complaint in the Circuit Court. The filing of the NOI temporarily pauses (tolls) your statute of limitations, but once mediation fails, you have a very short window to file the official lawsuit.

How Much Does the Pre-Suit Process Cost?

Getting past the pre-suit phase is often the most expensive part of a malpractice claim because of the required medical experts.

  • Expert Witness Affidavit: Finding a doctor willing to testify against another doctor, having them review hundreds of pages of records, and drafting the affidavit typically costs between $3,000 and $7,500.
  • Mediator Fees: Professional mediators in South Carolina charge between $250 and $400 per hour. This cost is usually split evenly between the plaintiff and the defense.
  • Lawyer Fees: Most attorneys from our directory handle these upfront costs on a contingency basis, meaning you don't pay out of pocket, but the costs are deducted from your final settlement.

How Long Does the Pre-Suit Phase Take?

Gathering medical records and finding an expert to sign the affidavit usually takes 2 to 4 months. Once the Notice of Intent is filed, state law requires mediation to occur within 120 days. If you successfully settle during mediation, the entire process could be over in 6 months. If mediation fails, the actual lawsuit begins, which can take an additional 1 to 3 years.

Frequently Asked Questions (FAQ)

What happens if I file a lawsuit without the expert affidavit?

If you fail to file the expert affidavit simultaneously with your Notice of Intent, the judge will dismiss your case. South Carolina courts offer very little leniency for skipping this mandatory step.

Can the expert be a general practitioner if I am suing a neurosurgeon?

Generally, no. Under S.C. Code Ann. § 15-36-100(A)(2), board certification is one way to qualify, but an expert can also qualify by demonstrating actual professional knowledge resulting from active practice or teaching in that specialty for at least 3 of the last 5 years preceding the opinion. A general practitioner cannot testify against a neurosurgeon unless they satisfy these rigorous statutory criteria.

Do I have to speak during the pre-suit mediation?

You are required to attend the mediation in person, but your attorney will handle the majority of the speaking and negotiations on your behalf. The mediator may ask you basic questions, but it is an informal process, not a trial.

Does filing the Notice of Intent automatically extend my statute of limitations?

Filing the NOI tolls (pauses) the statute of limitations. Depending on when you file the NOI in relation to your original deadline, state law grants a specific grace period (often 60 days) after mediation fails to file the actual lawsuit.
