Plain-language answers
Tortious interference occurs when someone outside a business relationship intentionally and improperly disrupts an existing contract or a business opportunity, causing harm. Examples may include inducing a breach, diverting a customer through wrongful conduct, or using threats, deception, or defamation to prevent a likely deal. The conduct must be more than ordinary competition or hard bargaining.
For interference with a contract, Ohio generally requires a valid contract, the defendant’s knowledge of it, intentional procurement of its breach, lack of privilege or justification, and damages. A prospective-relationship claim generally requires a reasonable probability of a business relationship, knowledge, intentional interference by improper means, and damages. The precise elements depend on the claim and facts.
Contract interference concerns an existing, enforceable agreement and a defendant’s efforts to cause its breach. Prospective interference concerns a relationship or opportunity that was reasonably likely to produce business but was not yet a completed contract. Ohio courts typically look for improper means in the prospective-relationship context, and a mere hope of doing business is usually not enough.
A competitor, customer, former employee, vendor, or other outsider may be liable if the required elements are proven. A party generally cannot interfere with its own contract, but an owner, officer, or agent may face individual exposure when acting outside a protected role or for an improper purpose. Whether a person is truly an outsider and whether conduct was privileged are fact-specific questions.
Potential damages may include lost profits, the value of a lost contract or opportunity, replacement or mitigation costs, and other losses caused by the interference. The business must show causation and damages with reliable, non-speculative evidence. Punitive damages may be available in an appropriate Ohio tort case when the required showing of actual malice is met; recovery and fee issues depend on the facts and law.
Preserve the contract or evidence of the prospective relationship, proposals, customer or vendor records, communications, personnel records, and a timeline showing what the defendant knew and did. Evidence of threats, deception, defamation, confidential information, or other improper means may be important. Sales records, lost-opportunity analyses, witnesses, and expert testimony can help connect the conduct to the claimed loss.
Common defenses include privilege, justification, lack of knowledge, no valid contract or reasonable probability of a relationship, no intentional procurement, no improper means, lack of causation, speculative damages, and the limitations period. Legitimate competition and truthful persuasion are generally not enough by themselves to support liability, although the method and purpose of the conduct matter.
Tortious interference focuses on a particular contract, relationship, or likely opportunity and the improper conduct that disrupted it. Unfair competition is a broader category that may include passing off, deceptive marketing, misuse of confidential information, or other commercially unfair conduct. The claims can overlap, but each requires its own legal elements and proof.
Ohio generally applies a four-year limitations period to tortious-interference claims as claims for injury to personal or property rights under Ohio Revised Code § 2305.09. The period typically depends on when the injury and claim accrued, and related contract, defamation, trade-secret, or statutory claims may have different deadlines. Confirm the dates promptly rather than relying on a general period.
Contact counsel when a customer, employee, vendor, or business opportunity is being diverted; a contract partner threatens to breach; or you learn that a competitor or outsider contacted the relationship. Early review can help preserve messages and records, evaluate privilege and improper means, and calculate losses before evidence or the Ohio deadline becomes harder to address. The facts control the available options.
This page provides general information about Ohio tortious-interference claims; it is not legal advice and does not create an attorney-client relationship. Whether conduct was privileged, justified, improper, or the cause of a recoverable loss depends on the relationship, communications, timeline, records, and other facts. No result is guaranteed.
