What qualifies someone to testify as an expert witness in my Georgia case?

· 3 min read

A person becomes an expert witness in Georgia by having specialized knowledge that can help the jury, based on knowledge, skill, experience, training, or education. Under O.C.G.A. § 24-7-702, qualification is the first hurdle, and it is tied to the specific subject the witness intends to address, not to titles in the abstract.

The qualification requirement

The rule does not demand a particular degree or license for every field. A witness can qualify through formal education, through practical experience, or through some combination. What matters is whether the person’s background gives genuine expertise about the matter on which the opinion will be offered. A physician may qualify to discuss a medical diagnosis, an engineer to discuss how a part failed, an accident reconstructionist to discuss vehicle dynamics, each within the area where their training or experience actually lies.

Qualification is subject-specific. Being an expert in one area does not make a witness an expert in a neighboring one. A general surgeon, for example, may not be qualified to give opinions that fall within a different medical specialty. The court matches the witness’s demonstrated expertise to the precise question being asked.

Beyond credentials: reliability and relevance

Qualification alone is not enough to get an opinion before the jury. Even a well-credentialed witness must also clear the rest of section 24-7-702. The court, acting as gatekeeper, additionally requires that:

  • The opinion rests on sufficient facts or data rather than assumption.
  • It is the product of reliable principles and methods.
  • Those methods were applied reliably to the facts of the case.
  • The testimony is relevant and will help the jury understand the evidence or decide a fact in issue.

So a person can be qualified by background yet still be barred if the method behind the opinion is unsound. Credentials open the door; reliability and relevance keep it open.

Georgia also imposes special requirements in certain contexts. In medical malpractice cases, for instance, an expert giving a standard-of-care opinion generally must satisfy added criteria about recent and regular practice or teaching in the relevant area, and the law requires an expert affidavit to accompany the complaint under O.C.G.A. § 9-11-9.1. These heightened rules apply on top of the general qualification standard.

The bottom line

A witness qualifies as an expert in Georgia by having knowledge, skill, experience, training, or education that genuinely fits the issue at hand under O.C.G.A. § 24-7-702. But qualification is only the start: the opinion must also be reliable and relevant, and some fields, such as medical malpractice, carry additional statutory requirements.
