How Hard Is It to Prove Tortious Interference in Florida?

How hard is it to prove tortious interference? It is demanding. In Florida, the claim targets a third party who intentionally and without justification disrupts a contract or business relationship. In trust and estate disputes, it often comes up when someone pressures a family member or blocks an expected distribution. This page covers the elements, why proof stalls, the evidence that tends to matter, the defenses, and the remedies.

What Tortious Interference Means in Trust and Estate Disputes

Tortious interference is a claim against someone who intentionally and without justification disrupts another person’s contract or business relationship.

In trust and estate matters, the claim often looks like this. A person pressures an older parent to change a will or trust. Or a person blocks a distribution a beneficiary was counting on. Courts ask whether the interference was deliberate and whether it was justified.

Tortious interference asks whether a third party wrongfully disrupted a relationship. The two are often pleaded together, so you may hear both terms in one case.

Expected inheritances raise a harder question. Courts look for a real, identifiable expectation, not a hope. For the broader picture, see our trust litigation overview.

The Elements a Claimant Must Prove

For a business relationship, Florida courts use four elements:

1. The existence of a business relationship.
2. The defendant’s knowledge of that relationship.
3. An intentional and unjustified interference by the defendant.
4. Damage to the plaintiff from the breach of the relationship.

The Third District states these elements in Ozyesilpinar v. Reach PLC. The court also explains that the relationship must rest on an actual and identifiable understanding or agreement. That agreement must in all probability have been completed without the interference.

A contract claim follows a similar path.

Proof that the defendant meant to interfere does not fill a gap in the relationship.

Why Proof Is Difficult

Proof gets hard because intent, justification, causation, and damages each invite a fight. Each one needs facts, and those facts are often out of the claimant’s hands.

Intent. The claimant must show the defendant meant to interfere. A relative who benefited from a change may say they never meant to take anything from anyone.

Justification. A defendant often points to a legitimate reason. The claimant then has to show the conduct was unjustified.

Causation. Causation is often the most contested point. A parent may change a will for many reasons, such as a health decline or a family rift. The claimant must connect the defendant’s conduct to the loss.

Damages. The claimant must show an actual loss. A hoped-for inheritance is hard to measure while an estate is still open.

Many key facts sit with banks, lawyers, or family members. Getting those records takes time, and the claimant may not control the timing.

Burden of Proof and the Evidence That Tends to Matter

The claimant carries the burden of proof on each element of the claim. Florida’s trust contest statute places a similar burden on the contestant, who must establish the grounds for invalidity (Fla. Stat. § 736.0207). Then the contestant must establish the grounds for opposing probate (Fla. Stat. § 733.107).

They show how Florida places the burden in related disputes.

In probate proceedings, the rules of evidence for civil actions apply unless the probate code changes them (Fla. Stat. § 731.1035).

Courts commonly weigh written communications, the timing of document changes, account records, witness accounts, and the defendant’s stated motives. A clear timeline often matters more than a general sense that something was unfair. Dates, who was present, and what changed on which day can carry real weight. How strong the evidence is depends on the facts of each matter.

Defenses, and Being the One Sued

Yes, a person can be sued for tortious interference. Defendants may include a family member, a new companion, a business rival, or an advisor who acted outside a legitimate role.

Common defenses follow the elements. A defendant may argue there was no valid contract or relationship, no knowledge of it, a justified reason for acting, or no link to the claimed loss. Each defense tests one element, so a defendant often starts by checking which element is weakest.

A person who acted within a legitimate role, such as a fiduciary following the governing document, may face a different analysis. The core question still turns on whether the conduct was justified.

If you’re the one named, the same elements apply to you. Where the claim overlaps with undue influence, see our undue influence page.

Remedies, Punitive Damages, and Next Steps

That is the core remedy for the harm.

In trusts, Florida law treats a trust, or the part of it, as void if fraud, duress, mistake, or undue influence procured it (Fla. Stat. § 736.0406). Timing can be short. An action to contest the validity of a trust that was revocable at the settlor’s death is barred, if not commenced within the earlier of: (1) The time as provided in chapter 95; or (2) Six months after the trustee sent the person a copy of the trust instrument and a notice informing the person of the trust’s existence, of the trustee’s name and address, and of the time allowed for commencing a proceeding (Fla. Stat. § 736.0604).

Punitive damages are a separate request.
