Clients hire professionals to handle the parts of a business they cannot handle themselves, and that is exactly what makes professional negligence so expensive. A missed filing deadline, an unread indemnity clause, an audit that certified numbers nobody verified, a tax position taken without support: by the time the client discovers the error, the underlying opportunity is usually gone, the loss has compounded, and the professional’s file has been rewritten in hindsight through memos that appeared after the fact. Having litigated these cases from both sides, I can say the hardest thing about a professional malpractice claim in Florida is not proving the professional made a mistake. It is proving the mistake, rather than the client’s own business, caused the loss.
A word of caution before anything else: professional malpractice claims run on short clocks and unforgiving proof requirements, and clients routinely destroy their own cases in the first weeks. They fire the professional and demand the file back without preserving the electronic record. They vent by email in ways that later read as ratification. They settle the underlying case cheaply, then discover that the settlement is now the ceiling on what they can claim was lost. Worst of all, they wait, on the theory that the professional promised to fix it, while a two-year limitations period runs. If you suspect a professional error, do three things before anything else: request the complete file in writing, preserve every communication on both sides, and have independent counsel evaluate the timeline before you make any move in the underlying matter.
This article explains how Florida treats claims against lawyers, accountants, and other professionals: what must be proven, who is permitted to sue, how the deadlines actually run, and what a successful claim recovers.
The elements: negligence is only the first half
A Florida legal malpractice claim requires three things: the attorney’s employment, the attorney’s neglect of a reasonable duty, and proof that the neglect was the proximate cause of loss to the client. Accounting malpractice claims track the same structure, substituting the professional standards that govern the engagement, and claims against other licensed professionals follow suit.
That third element does the real work. Florida requires the plaintiff to prove not merely that the professional performed below the standard of care, but that competent performance would have produced a materially better outcome. In litigation malpractice, this is known as the case within a case: the client must effectively try the original matter inside the malpractice trial, proving that the underlying claim or defense would have succeeded, and, in most circumstances, that any resulting judgment would have been collectible. A lawyer who blows a limitations deadline on a claim against a defunct, uninsured, judgment-proof defendant has committed malpractice that produced no recoverable damages.
Transactional malpractice presents the same problem in different clothing. The client must show what the deal would have looked like had the professional performed properly: that the counterparty would have accepted the missing protection, that the tax election would have been available, that the audit failure changed a decision the client would otherwise have made. This is why the strongest professional malpractice cases are built from contemporaneous documents, the engagement letter, the drafts, the markups, the emails, rather than from recollection.
Standard of care and the expert requirement
Except in cases of obvious error, such as missing a filing deadline outright, Florida requires expert testimony to establish the professional standard of care and its breach. In legal malpractice, the expert is generally a lawyer experienced in the relevant field. In accounting malpractice, the expert typically opines by reference to GAAP and, in audit engagements, GAAS: whether the workpapers support the opinion issued, whether professional skepticism was exercised, whether red flags were followed. Florida applies the Daubert standard to expert admissibility under Fla. Stat. § 90.702, meaning the opposing side will challenge the methodology, not just the conclusion, and a defense motion to exclude the plaintiff’s standard-of-care expert is often the whole case.
Engagement letters matter enormously here, because they define the scope of the duty. A professional is not liable for failing to do work that the engagement expressly excluded, which is why the first document produced in these cases is also usually the most important.
Who may sue: privity and its narrow exceptions
Florida generally requires privity: the plaintiff must have been the professional’s client. Disappointed third parties who relied on the work usually cannot sue for negligence, and defendants raise this defense early and often.
The exceptions are narrow but important:
- Intended-beneficiary estate planning. Florida permits a claim by a beneficiary where the client’s intent, as expressed in the will or trust, is the direct and express object of the engagement and the drafting error defeated it. Claims that the testator “really meant” something the documents do not say fail on this rule.
- Accountants and known third-party reliance. Fla. Stat. § 473.318 limits an accountant’s negligence exposure to those in privity, with an exception where the accountant knew the client intended the work product to be supplied to, and relied on by, an identified third party. Lenders and investors who received financial statements without that knowledge on the accountant’s part face a substantial hurdle.
- Fraud and other intentional torts. Privity limits negligence claims. A professional who participates in a fraud, or who aids a client’s breach of fiduciary duty, may face claims from parties who were never clients at all.
Related claims frequently travel alongside the malpractice count. Where the professional put personal interests ahead of the client’s, a breach of fiduciary duty claim may reach conduct that negligence law does not, and it can support fee forfeiture, a remedy that returns compensation paid for tainted work regardless of whether the underlying matter would have been won.
The deadlines: two years, and a four-year wall
Under Fla. Stat. § 95.11(4)(a), professional malpractice claims must be filed within two years from the time the cause of action is discovered or should have been discovered with the exercise of due diligence, subject to an outer four-year statute of repose running from the act or omission itself. Fraudulent concealment can extend the repose period, but that is an exception nobody should plan around.
Florida applies a specific accrual rule to litigation malpractice: the claim generally does not accrue, and the two years do not begin, until the underlying case is concluded by a final judgment that has become final, which for an appealed case means the appellate mandate. The rule is protective, since it avoids forcing clients to sue their lawyers while the underlying appeal is pending, but it is also a trap. Transactional malpractice does not enjoy it. There, the clock typically starts when the client knew or should have known of the redressable harm, which can be the day the deal closed with the defective clause, years before the consequences surface.
Hypothetically: a Palm Beach County manufacturer learns in year five that its counsel omitted an assignment provision from a supply agreement signed in year one, and the omission just cost it a buyer in a sale of the company. The negligence may be plain, and the loss enormous, but the four-year repose ran from the drafting, not from the failed sale. Timing analysis, not liability analysis, decides that case.
What a professional malpractice claim actually recovers
Damages in these cases are compensatory and economic, and Florida requires them to be proven with reasonable certainty rather than estimated:
- The lost judgment or defense, reduced by collectibility, in litigation malpractice.
- The difference in the deal, such as the value of protections that should have been obtained, the tax consequence that should have been avoided, or the investment loss that proper work would have prevented.
- Fees paid to the professional for the defective work, and fees reasonably incurred to fix it.
- Consequential losses proximately traceable to the error, subject to Florida’s rules on lost profits, which require proof of an established track record or a reasonable yardstick rather than projection.
Two limits deserve attention. First, attorney’s fees for prosecuting the malpractice case are generally not recoverable as damages absent a statute or contract, which changes the settlement math on smaller claims. Second, punitive damages require leave of court under Fla. Stat. § 768.72, meaning a plaintiff must first proffer evidence showing intentional misconduct or gross negligence before punitive claims may even be pleaded. Modeling all of this properly at the outset is the province of our financial damages practice, and it is where cases are valued realistically or not at all.
One practical note on the defense side: nearly every professional carries a claims-made policy, which covers claims first made and reported during the policy period. Professionals who receive a complaint letter and delay notifying their carrier can convert a covered claim into an uncovered one. Clients should understand the mirror image of the same fact, since the insurance, not the professional, usually funds the recovery.
Frequently asked questions
Do I have to prove I would have won the underlying case? In litigation malpractice, yes. Florida’s case-within-a-case rule requires proof that the underlying claim or defense would have succeeded, and generally that the judgment would have been collectible from the underlying defendant.
How long do I have to sue my lawyer or accountant in Florida? Two years from when you discovered, or should have discovered, the harm, with an outer four-year repose from the act or omission. Litigation malpractice claims generally accrue when the underlying case becomes final on appeal, but transactional claims can expire before the damage is visible.
Can I sue an accountant who audited a company I invested in? Usually only if you were in privity, or if the accountant knew the work was intended for you specifically. Section 473.318 limits negligence liability to those relationships, though fraud-based claims are not subject to the privity requirement.
Is a bad result the same as malpractice? No. Professionals are held to the standard of reasonably competent practitioners, not to a guarantee of outcome. Judgment calls that turn out badly, made competently and with informed client consent, are not actionable.
Do I need an expert to bring the claim? In nearly every case, yes. Florida requires expert testimony on the standard of care except where the breach is obvious to a layperson, and the expert’s methodology will face a Daubert challenge.
Can I recover my legal fees for the malpractice case itself? Generally no. Absent a contract or statute providing for fees, the fees incurred to prosecute a malpractice claim are not recoverable damages, though fees paid to the negligent professional, and fees spent correcting the error, often are.
