The Case You Must Prove Before You May File It
Florida is one of the hardest states in the country to sue a doctor or hospital, and Chapter 766 is the reason.
Before a malpractice complaint may be filed, the claim must survive a mandatory presuit process.
An investigation, a corroborating affidavit from a qualified medical expert, a formal notice, and a 90-day defense investigation window all come first.
Fumble a step and a valid case can die on procedure.
And at the end of the window sits a fork, the arbitration election, with consequences most victims never see coming.
Here is the whole path, step by step.
At-a-Glance: Chapter 766 Presuit
- No malpractice suit may be filed without presuit investigation and expert corroboration
- Formal notice to each defendant starts a 90-day no-filing window
- The statute of limitations tolls during the notice period
- Each defendant must reject with its own expert, offer settlement, or offer arbitration
- The arbitration election carries damage caps and fee-shifting that change everything

The Presuit Timeline From First Call to Courthouse
The process runs in sequence, and each stage has its own clock.
| Stage | What Happens | The Clock |
|---|---|---|
| Investigation | Records collected; qualified expert reviews the care | Runs inside the 2-year limitations period |
| Notice of intent | Formal notice with records, provider list, and the corroborating expert affidavit | Tolls the statute of limitations once served |
| Defense window | Defendant investigates; informal discovery both ways; no suit may be filed | 90 days |
| The response | Rejection with counter-affidavit, settlement offer, or arbitration offer | By day 90; silence counts as rejection |
| Filing | Suit may be filed after rejection or failed negotiation | 60 days or the remaining limitations period, whichever is greater |
Step One: The Investigation Behind the Claim
Chapter 766 requires the claimant to conduct an investigation establishing reasonable grounds to believe the provider was negligent and that the negligence caused the injury.[1]
In practice, that means the complete medical records, from every provider who touched the care, reviewed by physicians who know what the standard required. Incomplete records produce failed investigations, and hospitals do not always produce complete records on the first request. Chasing down the missing imaging, the audit trail, and the nursing notes is unglamorous work that decides cases.
Step Two: The Expert Affidavit That Opens the Door
"The affidavit is the ticket. Without a qualified expert's sworn corroboration, there is no notice, no case, and no courtroom."
The claim must be corroborated by a verified written medical expert opinion, served with the notice of intent. Florida's qualification rules are demanding: in general, the corroborating expert must practice in the same specialty as the defendant and meet strict experience requirements.
The affidavit is also discoverable, and the expert's history of prior disqualifications must be disclosed. A weak affidavit from a marginal expert invites a motion attacking the presuit process itself, which is why the choice of corroborating expert is a strategic decision, not a formality.
Defendants live under a mirror-image rule: a rejection of the claim must be corroborated by the defense's own verified expert opinion. The presuit phase is, in effect, the first expert-versus-expert round of the case.
Step Three: The 90-Day Notice Window
Formal notice goes to every prospective defendant by verifiable delivery, with the records, a list of the claimant's providers, and executed authorizations. From delivery, no suit may be filed for 90 days while the defense investigates.[2]
The window has teeth on both sides. Informal presuit discovery runs in both directions: unsworn statements, document demands answerable within 20 days, and examinations. Refusing reasonable presuit discovery carries sanctions. But nothing generated in presuit evaluation is admissible later, which makes the window a genuine investigation rather than a trap-laying exercise.
Two protections matter for the deadline math. The statute of limitations tolls during the 90-day window, and after a rejection the claimant has 60 days or the remainder of the limitations period, whichever is greater, to file. Those rules save cases, but they do not create time for an investigation that started too late. The Florida med-mal deadline rules and the presuit process have to be run together.
The Fork at Day 90: Rejection, Settlement, or Arbitration
By the end of the window, each defendant must do one of three things, and the third option hides the sharpest edges in Chapter 766.
Rejection sends the case to court, and it must come with the defense expert's corroborating affidavit. Silence through day 90 counts as rejection.
Settlement ends it, on terms the presuit investigation has now equipped both sides to price.
Arbitration is the fork. A defendant may offer voluntary binding arbitration on damages, which concedes liability but caps noneconomic damages at $250,000 per incident under a percentage-based formula, bars punitive damages, and puts the arbitration costs and a capped fee award on the defendant.[3]
The consequences of refusing run both ways.[4] A defendant who refuses a claimant's arbitration offer faces trial damages plus attorney's fees up to 25 percent of the award. A claimant who refuses a defendant's arbitration offer walks into trial with noneconomic damages capped at $350,000 per incident. In a catastrophic injury case, accepting or refusing that offer can be a seven-figure decision, and it must be made on a 30-day clock.
This is the part of the process where experienced counsel earns the fee.
Defendants do not offer arbitration to be generous. Families hear 'liability admitted' and want to say yes. Sometimes yes is right. Sometimes it trades a jury's verdict for a quarter of it. The only honest answer comes from valuing the case under both sets of rules first. A seven-figure decision should never be made on instinct. Whether to accept is arithmetic, not emotion, and we run the numbers before the clock runs us.
Florida Presuit Process FAQ
- Can I file a medical malpractice lawsuit in Florida without going through presuit?
-
No. Chapter 766 makes the presuit process mandatory: a reasonable investigation, a corroborating verified expert opinion, formal notice to every prospective defendant, and the 90-day investigation window all must come before the complaint. A suit filed without compliance faces dismissal, and depending on the deadline math, dismissal can end the claim permanently. The process is not optional paperwork; it is the case's first battlefield.
- Does the 90-day presuit period pause the statute of limitations?
-
Yes. The limitations clock tolls while the 90-day window runs, and after a rejection the claimant gets 60 days or the remainder of the limitations period, whichever is greater, to file suit. What the tolling cannot fix is a late start: the investigation and expert affidavit must be completed within the original limitations period, and they take months. Families who wait until the deadline is near may run out of room to build a compliant claim.
- What is the arbitration option in Florida malpractice cases?
-
After presuit, either side may offer voluntary binding arbitration on damages. If accepted, liability is conceded and a panel decides damages, with noneconomic damages capped at $250,000 per incident, no punitive damages, and the defendant paying arbitration costs plus a capped attorney fee. Refusing has consequences: a defendant who refuses faces fee-shifting at trial, and a claimant who refuses faces a $350,000 noneconomic cap at trial. The election deserves careful, case-specific math before anyone answers.
- What happens during the 90-day window?
-
The defense investigates with its insurer or review panel, and both sides may take informal presuit discovery: unsworn statements, document requests answerable in 20 days, and examinations. Nothing generated in the presuit evaluation is admissible at trial. By day 90 the defendant must reject the claim with its own expert affidavit, offer to settle, or offer arbitration; silence counts as rejection, and the case may then be filed.
