Can You Sue Someone for Interfering With Your Business?

Posted by Aaron R. Resnick | May 12, 2026

Short Answer

Florida law may provide a claim when someone knowingly and intentionally interferes with an existing contract or a sufficiently identifiable business relationship, without legal justification, and causes damage. Not every lost customer or aggressive competitor creates liability. The relationship, the defendant's knowledge, the specific interfering act, privilege or justification, and causation must be proven. Start by preserving communications with the customer, employee, vendor, investor, or contracting party, along with evidence showing what changed after the interference.

When This Becomes Urgent

  • The interference is continuing and threatens a major contract, closing, employee team, or customer account.
  • Confidential information, false statements, coercion, or a related lawsuit is being used to disrupt the relationship.
  • The lost opportunity will become difficult to prove unless current records and witnesses are preserved.

What Usually Goes Wrong

  • Treating ordinary competition or a party's own contract decision as unlawful interference.
  • Failing to identify a concrete relationship rather than a hope of future business.
  • Overlooking contract, trade secret, defamation, fiduciary, or conspiracy issues arising from the same conduct.

Why Miami Experience Matters

Miami commerce runs on relationships among developers, brokers, investors, hospitality groups, lenders, professionals, and international businesses. A local litigator understands how those relationships are formed and how interference actually occurs in this market. That context helps distinguish a legitimate competitive move from a targeted effort to derail a known deal, and it helps explain the economic harm in terms a Miami judge or jury can understand.

Local proof: independent media coverage

What to Have Ready

  • The contract or documents defining the business relationship.
  • Proof the defendant knew about that relationship.
  • Messages, statements, offers, or conduct showing the alleged interference.
  • Communications from the customer or counterparty explaining what changed.
  • Financial records supporting lost revenue, profit, or transaction value.

What Typically Happens Next

Counsel identifies the protected relationship, reconstructs the interfering conduct, and tests justification, causation, and damages. A preservation or cease and desist demand may be appropriate, especially if conduct is ongoing. Litigation can provide discovery into communications the claimant cannot access. The case should remain focused on a specific relationship and measurable harm rather than a broad complaint that someone acted unfairly.
