Section 12-2602 - Preliminary expert opinion testimony; certificationA. If a claim against a licensed professional is asserted in a civil action, the claimant or the claimant's attorney shall certify in a written statement that is filed and served with the claim whether or not expert opinion testimony is necessary to prove the licensed professional's standard of care or liability for the claim.B. If the claimant or the claimant's attorney certifies pursuant to subsection A that expert opinion testimony is necessary, the claimant shall serve a preliminary expert opinion affidavit with the initial disclosures that are required by rule 26.1, Arizona rules of civil procedure. The claimant may provide affidavits from as many experts as the claimant deems necessary. The preliminary expert opinion affidavit shall contain at least the following information:1. The expert's qualifications to express an opinion on the licensed professional's standard of care or liability for the claim.2. The factual basis for each claim against a licensed professional.3. The licensed professional's acts, errors or omissions that the expert considers to be a violation of the applicable standard of care resulting in liability.4. The manner in which the licensed professional's acts, errors or omissions caused or contributed to the damages or other relief sought by the claimant.C. The court may extend the time for compliance with this section on application and good cause shown or by stipulation of the parties to the claim. If the court extends the time for compliance, the court may also adjust the timing and sequence of disclosures that are required from the licensed professional against whom the claim is asserted.D. If the claimant or the claimant's attorney certifies that expert testimony is not required for its claim and the licensed professional who is defending the claim disputes that certification in good faith, the licensed professional may apply by motion to the court for an order requiring the claimant to obtain and serve a preliminary expert opinion affidavit under this section. In its motion, the licensed professional shall identify the following:1. The claim for which it believes expert testimony is needed.2. The prima facie elements of the claim.3. The legal or factual basis for its contention that expert opinion testimony is required to establish the standard of care or liability for the claim.E. After considering the motion and any response, the court shall determine whether the claimant shall comply with this section and, if the court deems that compliance is necessary, shall set a date and terms for compliance. The court shall stay all other proceedings and applicable time periods concerning the claim pending the court's ruling on the motion to compel compliance with this section.F. The court, on its own motion or the motion of the licensed professional, shall dismiss the claim against the licensed professional without prejudice if the claimant fails to file and serve a preliminary expert opinion affidavit after the claimant or the claimant's attorney has certified that an affidavit is necessary or the court has ordered the claimant to file and serve an affidavit.G. A claimant may supplement a claim or preliminary expert opinion affidavit with additional claims, evidence or expert opinions that are timely disclosed under the Arizona rules of civil procedure or pursuant to court order. An action under this chapter does not preclude a party from using a preliminary expert opinion affidavit for any purpose, including impeachment.
