The 90-Day Pre-Suit Period in Florida Medical Malpractice: Affidavit of Merit and Investigation Rules

In Florida, you cannot simply walk into a courthouse and file a lawsuit against a doctor or hospital for medical malpractice. To prevent frivolous claims, the state legislature created a rigorous, highly structured preliminary process that every patient must complete before litigation can officially begin. This mandatory phase requires substantial evidence, expert testimony, and strict adherence to deadlines. Because this process is filled with legal landmines, having professional legal representation is essential.

What is the 90-Day Pre-Suit Period?

Under Fla. Stat. § 766.106, a patient must conduct a good faith investigation to determine that reasonable grounds exist to believe that a medical provider was negligent. Once this investigation is complete, your lawyer will draft and send a formal Notice of Intent to Initiate Litigation to every doctor or hospital you intend to sue. Mailing this notice via certified mail triggers a mandatory 90-day pre-suit period. During these 90 days, you are legally prohibited from filing the actual lawsuit in a court, such as the Hillsborough County Circuit Court, Tampa or the Palm Beach County Circuit Court, West Palm Beach.

What Happens During the 90-Day Tolling Period?

While you wait, the statute of limitations is 'tolled' (paused). During these 90 days, the doctor's malpractice insurance company will conduct its own internal investigation. They have the right to request copies of your medical records, require you to answer written questions, and even conduct an unsworn interview to assess your injuries. The goal of this period is to encourage early settlements and weed out invalid claims. The importance of strict compliance with these pre-suit discovery rules was highlighted in the landmark case Kukral v. Mekras, 679 So. 2d 278 (FL Supreme Court 1996), which emphasized that the primary purpose is to promote settlement, not to create technical traps for patients.

The Affidavit of Corroboration: Your Medical Expert

The most difficult and expensive part of the pre-suit process is obtaining the Affidavit of Corroboration. Florida law demands that your Notice of Intent be accompanied by a sworn written statement from a qualified medical professional. This expert must review your medical records and state under oath that, in their professional opinion, the defendant doctor breached the standard of care and caused your injuries. Without this affidavit, your Notice of Intent is invalid, and your case will be dismissed.

Who Legally Qualifies as a Medical Expert in Florida Courts?

Florida imposes incredibly strict rules on who can serve as an expert witness. Under Fla. Stat. § 766.102, the expert must be in the exact same medical specialty as the defendant doctor. For example, if you are suing an emergency room physician, your expert must also be an actively practicing emergency room physician-not a cardiologist or a general surgeon. Furthermore, the expert must have devoted the majority of their professional time in the three years immediately preceding the malpractice to active clinical practice or consulting in that specific specialty. This ensures that only true peers are judging the defendant's actions.

Responding to the Defendant's Rejection or Voluntary Settlement Offer

By the end of the 90-day period, the defendant's insurance company must provide a formal response. They typically have three options:

• Reject the Claim: The insurer denies liability and provides their own expert affidavit stating the doctor did nothing wrong. Once rejected, you have 60 days (or the remainder of your statute of limitations, whichever is greater) to officially file your lawsuit.
• Offer a Settlement: The insurer admits liability and offers a financial settlement to cover your damages without going to court.
• Offer to Arbitrate: The defendant admits liability but disputes the amount of damages, offering to enter binding arbitration to decide the final payout.

Typical Costs for the Pre-Suit Investigation

Building a malpractice case before it even reaches a judge is a significant financial investment. While most lawyers work on a contingency fee (meaning you pay no attorney fees unless you win), the raw costs of the pre-suit phase can be steep:
