Expert witnesses can be important in Georgia premises liability cases, and a common misunderstanding is worth clearing up at the outset. The expert affidavit required by O.C.G.A. § 9-11-9.1, which must be filed with the complaint, applies only to claims of professional malpractice against licensed professionals and health care providers. A premises liability claim is not a professional malpractice claim, so that affidavit is generally not a requirement for filing one.
Experts are nonetheless frequently central to proving a premises case, because many of the issues are technical and fall outside a jury’s everyday knowledge. An engineer may analyze whether a stairway, handrail, or structure met building-code requirements, examining riser heights, rail dimensions, and construction details. A security expert may address whether the measures at a property were reasonable given the foreseeable risk, an issue that has grown more significant since Georgia CVS Pharmacy, LLC v. Carmichael. Human-factors and accident-reconstruction experts may explain how a fall or incident occurred.
Experts also support the damages side of a case. Medical experts describe the nature and extent of injuries, life-care planners project future treatment needs, and economists calculate lost earnings and the present value of future losses.
Not every premises case requires an expert. Questions such as whether a spill was present long enough to be discovered are often within ordinary understanding. But where the cause of an injury, the applicable standard, or the extent of harm depends on specialized knowledge, expert testimony frequently determines whether a claim can be proven.
