Who qualifies as a competent expert to sign my Georgia malpractice affidavit?


The person who signs a malpractice affidavit must be someone the law would actually let testify about the defendant’s conduct at trial. Georgia ties the affidavit requirement to its expert-competency rules, so a signature from an impressive but unqualified professional will not satisfy the statute.

O.C.G.A. § 9-11-9.1 calls for an affidavit from an expert “competent to testify.” Competency for medical experts is governed largely by O.C.G.A. § 24-7-702. That statute requires more than a license and a willingness to give an opinion. The expert must have genuine knowledge and experience in the area of practice involved, demonstrated through active practice or teaching in that field, and must have done so with enough regularity to support a reliable opinion on the procedure, diagnosis, or treatment at issue.

Because the affidavit expert and the trial expert face the same competency test, a plaintiff who chooses someone who could not testify risks an affidavit that fails on its face.

Factors that drive the qualification analysis

Several considerations typically determine whether a proposed expert is competent:

  • Active, recent involvement in the field. Georgia’s rule emphasizes practice or teaching in the relevant specialty during a recent period, rather than knowledge from the distant past.
  • A match to the conduct at issue. The expert’s background should align with the kind of care the defendant provided, since the opinion must address that care credibly.
  • Same profession as the defendant. As a general matter, the expert is expected to share the defendant’s profession when opining on professional judgment, with the statute setting the boundaries.

These requirements are exacting, and Georgia has been tightening the match between an expert’s specialty and the defendant’s. Confirming that a proposed signer meets the current version of the competency rule is part of preparing a sound affidavit.

The bottom line

A competent expert under O.C.G.A. § 9-11-9.1 is one who could actually testify under O.C.G.A. § 24-7-702, meaning a professional with recent, active experience in the relevant field whose background matches the care being challenged. Selecting a signer who satisfies that standard is what gives the affidavit, and the case behind it, a stable footing.
