Expert Witnesses in Georgia
Under Georgia law, an expert witness is defined by O.C.G.A. § 24-7-702. In simple terms, an expert is a witness who is qualified by knowledge, skill, experience, training, or education and whose specialized expertise will help the judge or jury understand evidence or determine a fact at issue. So, in Georgia, an “expert witness” is not just someone with credentials — it’s someone the court finds both qualified and reliable under § 24-7-702 before their opinion can reach the jury.
Rules Governing Disclosure
Under O.C.G.A. § 9-11-26, expert disclosure is governed primarily by subsection (b)(4), which distinguishes between testifying and non-testifying (consulting) experts.
For testifying experts, a party may, through interrogatories, require the opposing party to identify each expert expected to testify at trial, state the subject matter on which the expert will testify, and provide the substance of the facts and opinions to which the expert is expected to testify, along with a summary of the grounds for each opinion. The statute also permits the deposition of a testifying expert. Georgia does not automatically require a written expert report in every case (unlike Federal Rule 26), unless required by court order or specific statute.
For non-testifying (consulting) experts, discovery is generally prohibited. Their opinions and work are protected unless the requesting party shows exceptional circumstances under which it is impracticable to obtain the information by other means.
The statute also allows the court to impose conditions on expert discovery, including requiring the party seeking discovery to pay the expert a reasonable fee for time spent in deposition, and to allocate costs fairly.
Georgia courts frequently require parties to supplement or amend their expert disclosures as additional information becomes available, ensuring that all parties have a fair opportunity to review and respond to any updates or modifications to the expert’s opinions or testimony.
O.C.G.A. § 9-11-9.1 – Professional Negligence Claims
Under O.C.G.A. § 9-11-9.1, expert witnesses play a gatekeeping role in professional malpractice actions by requiring plaintiffs to file an expert affidavit contemporaneously with the complaint. The affidavit must be executed by a qualified expert competent to testify and must identify at least one specific negligent act or omission along with the factual basis for each allegation. This requirement serves to ensure that the claim has merit and is not frivolous before proceeding into discovery. Failure to file a compliant affidavit generally subjects the complaint to dismissal, although limited extensions may be available in certain circumstances.
Admissibility Standards
Georgia follows a Daubert-style reliability standard, meaning the court must determine that:
The expert is properly qualified.
The testimony is based on sufficient facts or data.
The testimony is the product of reliable principles and methods.
The expert has reliably applied those principles and methods to the facts of the case.
In Georgia medical malpractice cases, the statutory qualifications for expert witnesses are stricter than general expert standards and are set out in O.C.G.A. § 24‑7‑702. To qualify, an expert must first meet the general requirements of rule 702 (qualified by knowledge, skill, experience, training, or education). For medical malpractice specifically, the expert must:
Be licensed by an appropriate regulatory agency to practice the relevant profession at the time the alleged act or omission occurred.
Have actual professional knowledge and experience in the area of practice or specialty at issue through either active clinical practice or teaching for at least three of the last five years, with sufficient frequency to demonstrate appropriate expertise in performing, diagnosing, or treating the procedures or conditions central to the case.
Be in the same profession (and generally the same specialty) as the defendant whose conduct is at issue, although Georgia courts have interpreted this phrase with some flexibility in particular contexts.
Attorney–Expert Communication Protection
In Georgia, “attorney–expert communication protection” refers to the extent to which communications between a lawyer and a retained expert are shielded from disclosure during discovery.
Georgia does not automatically require disclosure of all communications between attorney and expert (unlike the broader disclosure concerns that existed in federal practice before the 2010 amendments). Draft reports and strategy discussions are generally protected as attorney work product — unless they contain discoverable facts, data, or assumptions that the expert relied upon in forming opinions.
In short, if the communication shaped the expert’s opinion (facts, assumptions, data provided), it may be discoverable but pure mental impressions, legal strategy, or attorney commentary are typically protected.
Compensation
In Georgia, expert witnesses are typically compensated through private agreements with the retaining party, usually on an hourly or daily rate for case review, report preparation, deposition, and trial testimony. Under O.C.G.A. § 9-11-26, if the opposing party seeks to depose a testifying expert, that party must pay the expert a “reasonable fee” for time spent in deposition, and courts may intervene if a dispute arises over what is reasonable. If discovery from a consulting (non-testifying) expert is permitted under exceptional circumstances, the court may require the requesting party to pay a fair portion of the expert’s fees and related costs. Importantly, experts may not be compensated on a contingency basis tied to the outcome of the case, as such arrangements would undermine credibility and admissibility.
State-Specific Statutes & Local Rules
Local Court Rules: Individual judicial districts may impose specific requirements regarding the format, content, and timing of expert disclosures. These local rules can supplement or refine statewide procedural rules.
Case-Specific Orders: Judges may issue scheduling or case management orders tailored to the complexities of a particular case. Such orders can modify, expand, or clarify the parties’ expert disclosure obligations.
