How Do I Prove a Product Was Defective in a South Carolina Injury Claim?

KEY TAKEAWAYS:

Proving a South Carolina product liability claim requires more than showing an injury happened while using a product; the claimant must show the product was defective, the defect made it unreasonably dangerous, and the defect caused the injury. Expert testimony, the physical product itself, and, when relevant and admissible, recall or similar-incident evidence are often the most persuasive evidence, which is why preserving that evidence early matters so much. How the product was being used at the time also matters, since South Carolina law can bar recovery when a person knowingly continues to use a product after discovering its danger.

Getting hurt by a product is not, by itself, enough to win a product liability claim in South Carolina. The law requires proof that the product was actually defective, that the defect existed when it left the defendant manufacturer’s or seller’s control, and that the defect caused the injury. Meeting that burden usually takes more evidence than most people expect, and the type of proof needed depends on which kind of defect is involved.

At Derrick Law Firm Injury Lawyers, our attorneys build defective product cases around the specific evidence South Carolina law requires, rather than relying on the fact that an injury happened while using the product. 

What Do You Have to Prove in a South Carolina Product Liability Claim?

South Carolina's products liability statute holds a seller strictly liable for physical harm caused by a product sold in a defective condition unreasonably dangerous to the user, as long as the seller is in the business of selling that type of product and the product reached the user without substantial change. In practice, this generally means proving:

• The product was defective when it left the manufacturer's or seller's control
• The defect made the product unreasonably dangerous to the user or consumer
• The defect, rather than some other cause, was responsible for the injury

Strict liability means you generally do not need to prove the seller or manufacturer was careless in how it designed or built the product. You still need to prove the defect itself, which is where most of the evidence in these cases comes in.

Do You Need to Identify Which Type of Defect Caused Your Injury?

Yes, and identifying the defect type is a key part of building the proof. South Carolina recognizes three types of product defects: manufacturing defects, design defects, and warning defects. Each type requires different evidence, so identifying the category early focuses the investigation instead of trying to prove everything at once.

A manufacturing defect claim typically compares the specific unit involved to how the product was supposed to be built. A design defect claim requires showing a feasible and reasonable alternative design existed. A warning defect claim typically centers on the danger associated with the product and the adequacy of the warnings or instructions provided.

Why Does Expert Testimony Usually Matter So Much?

Many technically complex product defect cases depend on expert testimony because the average juror cannot look at a broken part and know whether it failed due to a design flaw, a manufacturing error, normal wear, or misuse. An engineer, metallurgist, or other qualified expert may be needed to examine the product, review the manufacturer's specifications, and offer an opinion about what caused the failure.

South Carolina courts have excluded expert opinions that were not sufficiently reliable or that strayed outside the expert's actual area of qualification, which means the choice of expert, and the thoroughness of that expert's examination, could determine whether a case survives a defense challenge before it ever reaches a jury.

What Evidence Should You Preserve?

The physical product is frequently the single most important piece of evidence in a defective product case, and it is also the piece of evidence most likely to disappear if no one takes steps to preserve it. A few practical steps matter early on:

• Keep the product exactly as it was after the incident, without attempting repairs or cleaning that could alter or destroy evidence of the defect
• Preserve all packaging, manuals, receipts, and any parts that separated from the product during the incident
• Photograph the product, the scene, and any visible damage from multiple angles before anything is moved or repaired
• If possible, take steps to preserve a workplace machine or piece of equipment involved in a work injury so it can be inspected before repairs or alterations are made.

If the product has already been discarded, repaired, or lost, the case is not automatically over, but proving the defect becomes considerably harder without it.

How Do Recalls and Prior Incident Reports Help Prove a Defect?

A product recall or a pattern of similar complaints filed with a federal agency may support a claim when the recall or prior incidents involve substantially similar products, defects, and circumstances. The U.S. Consumer Product Safety Commission maintains public recall notices for consumer products, and a matching recall may provide useful supporting evidence when it involves the same product and alleged defect. A lack of a formal recall does not mean a product is safe, since many defective products are involved in injuries long before a recall is ever issued.

Does It Matter Whether the Product Was Used as Intended?

Yes. South Carolina law bars recovery when a person discovers a defect, understands the danger, and unreasonably continues to use the product anyway. A manufacturer can also argue that the product was misused in a way that was not reasonably foreseeable. This is one of the reasons the facts surrounding how the product was actually being used matter as much as the defect itself. Claims connected to defective truck parts causing a crash or boat and jet ski component failures often turn on exactly this question, since the manufacturer will look closely at how the product was being operated at the time.

Who Can Help Evaluate Whether You Have a Case?

Product defect cases move quickly in the early days after an incident, since evidence can be lost, products can be repaired or discarded, and witnesses' memories fade. Attorney DeShawn Mitchell previously represented manufacturers and their insurers in automotive product liability litigation before joining Derrick Law Firm Injury Lawyers. Now he represents injured parties in personal injury claims. A prompt evaluation of the defect involved and the evidence still available is usually one of the most useful things you can do early.
