Florida Tortious Interference Attorney

Cory Cannon represents Tampa Bay businesses harmed when an outside party wrongfully breaks up a contract, a customer relationship, or a deal in progress. The pattern is familiar. A competitor learns you are about to sign a supplier and feeds that supplier false information to kill the deal. A former employee walks out with your customer list and a rival starts calling every name on it. A general contractor was ready to award you the subcontract until someone with an interest in seeing you fail told the GC a story that was not true. You did not breach anything. Someone on the outside reached into a relationship that was working and took it apart on purpose.

That conduct has a name in Florida law: tortious interference, an intentional, unjustified act by a third party that damages a contract or business relationship you had with someone else. The word to hold onto is third party. This claim is against the outsider who interfered, not against the person on the other side of your contract. If your problem is with the party you actually signed with (they took your money and did not perform), that is a breach of contract, and it belongs on a different page. Tortious interference is what you bring against the person who reached in from outside.

This page explains what Florida requires to prove a tortious interference claim, the single hardest question in every one of these cases (where lawful competition ends and unlawful interference begins), and the companion statute, Florida’s Deceptive and Unfair Trade Practices Act, that often travels alongside it. It is part of our broader business litigation practice. If the relationship someone interfered with was a non-compete or other restrictive covenant an employee signed, read our non-compete page: enforcing the covenant and suing the competitor who induced its breach are two related but distinct claims we handle together.

What tortious interference actually covers

Florida recognizes two closely related versions of this tort, and the difference is whether a contract already existed.

Tortious interference with a contract applies when you already had a binding agreement and a third party induced the other side to break it. The classic move is a competitor who knows you have a signed supply contract and offers the supplier a sweeter deal specifically to get them to walk away from you. The existing contract is what makes the interference easier to prove: the relationship is documented, and the defendant’s knowledge of it is usually not seriously in dispute.

Tortious interference with a business relationship (sometimes called interference with an advantageous or prospective relationship) is broader. It does not require a signed contract at all. It protects relationships and dealings that were reasonably likely to produce business: a repeat customer, a bid you were the frontrunner to win, a vendor you had worked with for years on a handshake. Because there is no contract to point to, these cases turn harder on proving that a real, identifiable relationship existed and that the defendant knew about it and set out to wreck it.

The fact patterns that recur across Hillsborough, Pinellas, Manatee, and Sarasota counties tend to skew toward businesses that build things and the people who supply and staff them:

• A poached subcontractor. You had a sub committed to a project (sometimes on a bonded job) and a competitor lured the crew off mid-schedule to leave you exposed on your own deadlines.
• A killed supply deal. A rival told your supplier something false about your finances or your reliability to stop a purchase order from closing.
• The departing employee and the customer list. A former employee or partner left, took confidential customer and pricing information, and a competitor used it to systematically call your accounts. When a signed non-compete or non-solicitation agreement is involved, the covenant claim runs alongside the interference claim. See our non-compete page.
• The whisper to the decision-maker. Someone with a stake in your failure told a general contractor, a developer, or a property manager a false story that got you removed from a project or passed over for the next one.
• Interference with a closing deal. A third party inserted themselves into a pending sale, financing, or joint venture and blew it up to take the opportunity for themselves.

Where the outsider who interfered was one of your own vendors or business partners overreaching, our partnership dispute and vendor dispute pages may fit the facts better. Part of the first conversation is naming the right defendant and the right claim.

The four elements Florida requires

Every tortious interference case is measured against the four-part test the Florida Supreme Court set in Tamiami Trail Tours, Inc. v. Cotton. Each element is a place the claim can succeed or fail.

• 1. A business relationship or contract. There must be an identifiable relationship (with a specific customer, supplier, or counterparty) under which you had legal rights or a reasonable expectation of continued business. A general hope of doing business “with the market” is not enough; the relationship has to be concrete and identifiable.
• 2. The defendant’s knowledge. The interferer must have known the relationship existed. You cannot intentionally interfere with something you did not know about. Knowledge is often proved by circumstances: a former insider, a competitor in a small market, an email showing they knew about your deal.
• 3. Intentional and unjustified interference. The defendant must have intentionally acted to disrupt the relationship, and the interference must have been unjustified, meaning not privileged as ordinary competition. This is where most tortious interference cases are actually decided, and the next section is devoted to it.
• 4. Damage caused by the interference. You must show real harm (a lost contract, lost profits, a customer who left) that the interference caused. A relationship that fell apart for its own reasons, or a customer who would have left anyway, does not support the claim. Causation and damages are proved with records, not impressions.

Under Cotton, one point works in a plaintiff’s favor: the defendant’s motive does not have to be greed. A defendant who damaged your business relationships out of pure malice is just as liable as one who did it to win the business for himself. The tort punishes the intentional, unjustified harm regardless of why the defendant wanted to cause it.

You sue the outsider, not the party you dealt with

This is the distinction that decides who the defendant is, and it trips up a lot of business owners. Tortious interference is a claim against a stranger to the relationship. A party to the contract or relationship cannot tortiously interfere with it, because they are inside it, not outside it. Florida courts extend that rule further: someone who has a supervisory interest in how the relationship is conducted, or a legitimate financial interest in how the contract is performed, is generally not treated as a stranger either, and cannot be sued for interference.

The practical consequences are worth stating plainly:

• If the customer or supplier who walked away is the one you are angry at, your claim against them is a breach of contract claim, not tortious interference. The interference claim is aimed at whoever induced them to walk.
• If the person who “interfered” was actually a party to your agreement (a partner, a co-venturer, a manager with authority over the relationship), expect a fight over whether they were an outsider at all. Getting the defendant’s status right at the outset saves a claim that would otherwise be dismissed.
• You can, and often do, pursue both at once: the breach claim against the counterparty who left, and the interference claim against the third party who pulled them away. They are separate claims with separate proof.

The hard part: competition is not interference

This is the single most important thing to understand before spending money on a tortious interference case, and we say it early and plainly to every business owner who calls. Florida law favors competition. A competitor is allowed to go after the same customers you want, undercut your price, out-market you, and take business you thought was yours, and do all of it while privately hoping you fail. Florida courts have been explicit: so long as improper means are not used, steps taken to protect or advance your own financial and contractual interests are not actionable, even when they are taken with personal ill will toward a rival. Ethyl Corp. v. Balter, 386 So. 2d 1220 (Fla. 3d DCA 1980). This is the competition privilege, and the defendant will raise it in nearly every case.

So the claim does not turn on the fact that you lost business to a competitor. It turns on how they took it. Interference becomes actionable when the competitor used improper means: conduct that is wrongful independent of the competition itself. The recurring categories are:

• Fraud or deceit: false statements made to your customer or supplier to induce them to leave you.
• Defamation: lies about your company, your finances, or your work, published to the people you do business with.
• Threats, coercion, or intimidation: pressure that goes beyond a better offer.
• Inducing the breach of a contract the defendant knew about: persuading someone to break a binding agreement, as opposed to competing for their business once they are free to move.
• Misuse of trade secrets or confidential information: using stolen customer lists, pricing, or bid data to target your relationships.

The line is sharpest around at-will and prospective relationships. A competitor who offers your at-will customer a better price has done nothing wrong. A competitor who tells that customer you are about to go bankrupt, when it is not true, has crossed into interference. The facts that make or break these cases are usually in the emails, texts, and the words that were actually said to the customer. We build the case around that record, and we tell clients honestly, early, when the conduct they are describing sounds like hard competition rather than something a court will call improper. That candor is the point: a tortious interference suit that runs into the competition privilege is expensive and losing, and we would rather say so at the first meeting than after the bills pile up.

FDUTPA: the companion claim for unfair competition

When a competitor’s conduct was not just aggressive but genuinely deceptive or unfair, Florida’s Deceptive and Unfair Trade Practices Act often applies alongside the interference claim, and sometimes reaches conduct the competition privilege would shield from the tort by itself. FDUTPA, found at section 501.201 and following, prohibits “unfair methods of competition, unconscionable acts or practices, and unfair or deceptive acts or practices in the conduct of any trade or commerce.” Florida’s definition of a “consumer” under the Act includes business entities, so a business injured by a competitor’s unfair or deceptive practices can bring its own FDUTPA claim.

Two features make FDUTPA worth evaluating in almost every interference case:

• Actual damages. Under section 501.211, a party aggrieved by a FDUTPA violation may recover its actual damages. FDUTPA does not reach speculative losses or consequential damages the way a tort claim might, so the measure is narrower, but it is real, provable loss.
• Two-way attorney fees. Under section 501.2105, the prevailing party may recover reasonable attorney fees and costs after judgment and the exhaustion of any appeals. Since a 1994 amendment, that award is discretionary rather than automatic (the court “may” award fees), and it runs in both directions. A FDUTPA count can shift the winner’s fees onto the loser, which cuts for you if you prevail and against you if you do not.

That two-way fee exposure is exactly why FDUTPA is a strategic decision, not a reflex. Adding the count strengthens a strong case and raises the stakes on a weak one. We evaluate whether the facts support it before pleading it, not after.

Deadlines that control a Florida tortious interference claim

Tortious interference is an intentional tort, and Florida’s tort-reform reshuffling of the limitations statute did not change the period that governs it. The companion claims that usually travel with it, however, run on their own separate clocks, so a single dispute can carry several different deadlines.

Two cautions. First, “when the clock started” is a fact question: interference can be a single act or a course of conduct, and picking the wrong accrual date can cost the claim. Second, deadlines shift with facts and with legislative amendments; confirm yours with a lawyer rather than a webpage, including this one. The sooner the conduct is documented, the stronger every one of these claims is. Witnesses move on and emails get deleted.

What a tortious interference case is worth

The core measure of damages is the harm the interference caused: most often the profit you lost on the relationship that was destroyed. If a poached supply contract would have earned you a provable margin, or a lured-away subcontractor forced you to cover a job at a loss, that lost profit is the heart of the claim. Lost profits have to be proven with reasonable certainty, not guessed at, which is why we build these cases on your financial records and, where the numbers are contested, retain independent forensic accountants to establish them in a form a court will accept.

Because tortious interference is an intentional tort, punitive damages (an additional award meant to punish, not just compensate) may be available where the conduct was egregious. Florida gates that carefully: under section 768.72, a plaintiff cannot even plead punitive damages without first showing the court a reasonable evidentiary basis for them, and Florida law caps them in most cases. Punitive damages are the exception, not the expectation, and we treat them that way.

A companion FDUTPA claim adds its own actual-damages recovery and the two-way fee exposure described above. The right damages model depends on which claims the facts support and who the defendant is: a well-capitalized competitor and a departing employee with no assets present very different collection realities, and we talk through that honestly before anyone files.

Who pays the attorney fees

Start with the default: Florida follows the American Rule, under which each side ordinarily pays its own attorney fees. Tortious interference, standing alone, carries no fee-shifting statute. That is why the companion claims matter so much to the economics. A FDUTPA count carries the discretionary two-way fees of section 501.2105. A related contract claim may carry a prevailing-party fee clause. Those provisions can turn a case with modest damages into one worth pursuing, and can turn a weak case into an expensive one, because the exposure runs both ways.

Our billing follows the case. Business-litigation matters like these are commonly handled hourly, sometimes on flat-fee stages for defined work, with fee-shifting pursued wherever a statute or contract provides it. Where the damages are large and provable and the defendant is collectible, other arrangements are sometimes a fit. We tell you which model makes sense for your facts (and what the fee provisions in play mean for your downside) at the initial consultation, which is free.

How we work these cases

Cory Cannon was founded by a Florida attorney with a family history in construction for generations. That upbringing shapes how we work an interference case involving builders, suppliers, and the people who staff a job. We read subcontracts, purchase orders, bid documents, and schedules the way the people who wrote them do, and we understand how a competitor actually pulls a crew off a bonded project or slips a false word to a general contractor to get a rival removed. When a case turns on technical work (whether a job was really behind, whether the work at issue met code), we retain independent licensed engineers whose opinions we can put in front of a judge, a jury, or an arbitrator.

The through-line of our approach is that these cases are won on the record. Intent, knowledge, improper means, and causation all live in emails, texts, and the specific words said to your customer. We move early to preserve that evidence, and we give clients a straight read on whether what they are describing is unlawful interference or the hard competition Florida allows. That is part of the value: knowing which cases to bring and which to walk away from.

Where we handle these disputes

We represent businesses in the circuit courts of Hillsborough, Pinellas, Manatee, and Sarasota counties (Tampa, St. Petersburg, Bradenton, Sarasota, Venice, and the communities between) and in arbitration where a contract requires it. If a competitor, a former employee, or an outside party wrongfully broke up a contract, a customer relationship, or a deal you were about to close, bring us the agreement, the correspondence, and the timeline of what happened. We will tell you whether you have a claim, who the right defendant is, what it is worth, and what it will cost to pursue. Contact us for a free consultation.
