The Georgia expert affidavit: it goes with the complaint, not 60 days later
Georgia procedure · Last verified August 17, 2026
Most states that require an expert certification in a professional malpractice case give you a grace period after filing. New Jersey allows 60 days from the answer. Pennsylvania allows 60 days from the complaint.
Georgia requires the affidavit with the complaint. There is one exception, it is narrow, and the statute says in terms that the court may not extend it.
The requirement
O.C.G.A. § 9-11-9.1(a):
In any action for damages alleging professional malpractice against: (1) A professional licensed by the State of Georgia and listed in subsection (g) of this Code section; (2) A domestic or foreign partnership, corporation, professional corporation, business trust, general partnership, limited partnership, limited liability company, limited liability partnership, association, or any other legal entity alleged to be liable based upon the action or inaction of a professional licensed by the State of Georgia and listed in subsection (g); or (3) Any licensed health care facility alleged to be liable based upon the action or inaction of a health care professional licensed by the State of Georgia and listed in subsection (g), the plaintiff shall be required to file with the complaint an affidavit of an expert competent to testify, which affidavit shall set forth specifically at least one negligent act or omission claimed to exist and the factual basis for each such claim.
Two features worth separating.
The affidavit is the expert's, and it is filed. Unlike Pennsylvania, where the attorney certifies that an expert statement exists somewhere, Georgia puts the expert's own sworn affidavit into the record at the outset. It must identify at least one negligent act or omission and the factual basis for it.
And the entity is covered too. Subsections (a)(2) and (a)(3) reach the firm, the practice, the corporation and the hospital where the claim rests on a licensed professional's conduct. Suing the employer instead of the individual does not avoid the requirement.
Subsection (g) contains the list of covered professions — it is not limited to medicine.
The one exception
§ 9-11-9.1(b):
The contemporaneous affidavit filing requirement pursuant to subsection (a) of this Code section shall not apply to any case in which the period of limitation will expire or there is a good faith basis to believe it will expire on any claim stated in the complaint within ten days of the date of filing the complaint and, because of time constraints, the plaintiff has alleged that an affidavit of an expert could not be prepared. In such cases, if the attorney for the plaintiff files with the complaint an affidavit in which the attorney swears or affirms that his or her law firm was not retained by the plaintiff more than 90 days prior to the expiration of the period of limitation on the plaintiff's claim or claims, the plaintiff shall have 45 days after the filing of the complaint to supplement the pleadings with the affidavit. The trial court shall not extend such time for any reason without consent of all parties.
This is tightly gated, and each gate is a separate requirement.
| Requirement | What it means |
|---|---|
| Limitations expiring within ten days of filing | Or a good-faith basis to believe it will |
| An allegation in the complaint | That an affidavit could not be prepared because of time constraints |
| An attorney's affidavit filed with the complaint | Swearing the firm was not retained more than 90 days before the limitations period expired |
| Then, and only then | 45 days to supplement |
And the court cannot help you. "The trial court shall not extend such time for any reason without consent of all parties." That is about as absolute as procedural language gets — the only escape is the agreement of every opposing party.
Notice what the 90-day retention requirement is doing. The exception exists for the client who arrives at a lawyer's office days before the limitations period runs. A firm that has held the file for months cannot use it.
What happens if you miss it
The same subsection carries the consequence:
If either affidavit is not filed within the periods specified in this Code section, or it is determined that the law firm of the attorney who filed the affidavit permitted in lieu of the contemporaneous filing of an expert affidavit or any attorney who appears on the pleadings was retained by the plaintiff more than 90 days prior to the expiration of the period of limitation, the complaint shall be dismissed for failure to state a claim.
Two things to note.
"Either affidavit." Missing the expert affidavit and misusing the attorney affidavit produce the same result.
The retention question is auditable after the fact. A defendant can test when the firm was retained, and the statute makes a wrong answer fatal — not merely to the exception, but to the complaint.
One relief valve on limitations. § 9-11-9.1(c):
This Code section shall not be construed to extend any applicable period of limitation, except that if the affidavits are filed within the periods specified in this Code section, the filing of the affidavit of an expert after the expiration of the period of limitations shall be considered timely …
So using the 45-day route correctly does not cost you the limitations period on the affidavit itself.
How Georgia compares
| Georgia | Pennsylvania | New Jersey | North Carolina | |
|---|---|---|---|---|
| What is filed | the expert's own affidavit | the attorney's certificate | the expert's affidavit | a certification inside the pleading |
| When | with the complaint | with the complaint or within 60 days | within 60 days of that defendant's answer | with the complaint |
| Grace period | 45 days, in one narrow case | 60 days as of right | 60 more on good cause | limited |
| Court may extend | no, without all parties' consent | yes | yes, once | limited |
| Covers the employing entity | yes, expressly | yes | yes | — |
| Consequence of missing | dismissal for failure to state a claim | judgment of non pros by praecipe | dismissal, usually with prejudice | dismissal |
A short checklist
- Assume the affidavit is due with the complaint. Georgia has no general grace period.
- Check subsection (g) to confirm the profession is covered — the list is not limited to medicine.
- Remember the entity is covered. Suing the practice or the hospital rather than the individual does not avoid the requirement.
- The affidavit must state at least one negligent act or omission and the factual basis for it. A general attestation of malpractice is not enough.
- The 45-day route needs all four elements, including the attorney's sworn affidavit about the retention date.
- Do not plan on an extension. The court cannot grant one without the consent of all parties.
- Be able to prove when your firm was retained. A retention more than 90 days before the limitations period expired defeats the exception and dismisses the complaint.
- File within the statutory periods so that § 9-11-9.1(c) treats a post-limitations affidavit as timely.
