Tortious Interference in Texas Business Disputes

By Hank FasthoffJuly 6, 2026

Texas law protects contract rights while leaving room for lawful competition. A tortious interference claim therefore turns on the right the claimant possessed, the defendant's knowledge and purpose, the conduct that caused the loss, and the type of business relationship involved.

Texas recognizes separate claims for interference with an existing contract and interference with a prospective business relationship. An existing contract claim protects specific legal rights already created by an agreement. A prospective relationship claim requires proof of an independent tort or other unlawful conduct because neither party holds a contract right to the expected transaction.

That distinction affects the elements, defenses, damages, and evidence. A competitor may lawfully offer a customer better terms. Liability becomes possible when the competitor knowingly causes a breach of an existing right or uses independently wrongful conduct to prevent a probable transaction.

An Existing Contract Claim Requires a Specific Legal Right

A claimant alleging interference with an existing contract generally must prove four elements. A contract subject to interference existed, the defendant committed a willful and intentional act of interference, the act proximately caused injury, and the claimant incurred damage or loss. Inwood National Bank v. Fagin, 706 S.W.3d 342 (Tex. 2025).

The contract alone doesn't establish the first element. The claimant must identify a specific enforceable right under that agreement. If the contracting party exercised a right the contract allowed, persuading that party to act generally supplies no interference claim.

Fagin illustrates the limit. A trust agreement stated that a stockholder intended to transfer shares after the bank approved the transfer. The bank never approved it, and the stockholder retained the ability to decline the proposed transfer. The Supreme Court of Texas held that the beneficiary possessed no contractual right to the shares, so the bank couldn't have interfered with that right.

The court resolved Fagin on the absence of a contract right and declined to decide whether truthful information supplies an affirmative defense. Truth may affect intent, causation, or another element, but Fagin provides no categorical truth defense.

El Paso Healthcare System, Ltd. v. Murphy, 518 S.W.3d 412 (Tex. 2017), applies the same principle. A nurse anesthetist's agreement gave the hospital discretion over scheduling and provided no right to particular shifts. Removing him from the schedule therefore interfered with no legal right created by the contract.

Contract language often controls this issue before a court examines motive. Termination rights, approval conditions, discretion clauses, exclusivity provisions, and conditions precedent define the interest the tort protects. A claim framed around the business relationship in general may fail when the agreement granted no right to the disputed performance.

At Will Agreements Can Support a Claim

An agreement terminable at will remains valid until a party terminates it. In Sterner v. Marathon Oil Co., 767 S.W.2d 686 (Tex. 1989), the Supreme Court rejected at will status as a complete defense to interference with contract performance.

That rule preserves a claim during the agreement's life, but it supplies no rights absent from the contract. The claimant must identify the performance or legal interest affected by the defendant. A third party who persuades someone to exercise an unrestricted termination right presents a different case from one who causes a missed payment, a violation of exclusivity, or conduct that impairs performance before termination.

The distinction between an existing at will agreement and an expected future relationship also affects the required proof. A current agreement can support the existing contract claim. Expected renewals, future orders, and hoped for extensions may instead require the prospective relationship analysis.

Intent Requires Knowledge and Purpose

Interference must be willful and intentional. The defendant must desire the interference or believe it is substantially certain to result from the conduct. Knowledge of the contract plus participation in events surrounding a breach may prove insufficient when the evidence shows no purpose to cause interference.

Community Health Systems Professional Services Corp. v. Hansen, 525 S.W.3d 671 (Tex. 2017), applied that standard in a dispute over a physician's employment agreement. Intent focuses on interference with the contract, rather than a desire to injure the claimant. Emails, instructions, compensation proposals, recruiting communications, and statements to the contracting party often provide the most useful evidence.

Knowledge also has to concern the right at issue. Awareness that two companies conduct business together differs from knowledge of an exclusivity term, customer restriction, approval condition, or payment obligation. Pleadings and discovery should connect the defendant's information to the contractual provision allegedly affected.

Corporate Agents Usually Act as the Corporation

A contracting party can't interfere with its contract. The same rule generally protects an officer, director, manager, or employee acting as the corporation's agent because the agent acts for the contracting party rather than as a legal stranger.

Holloway v. Skinner, 898 S.W.2d 793 (Tex. 1995), requires evidence that the agent acted solely to further personal interests in a manner contrary to the corporation's interests. Personal benefit, hostility, or mixed motives alone don't satisfy that standard. A claimant has to separate an agent's poor business judgment from conduct undertaken solely for the agent.

Hansen applied the same rule and rejected liability against a corporate representative who acted within the company's interests. Your case assessment should address the agent issue near the beginning of any internal business dispute. Authority records, board instructions, reporting lines, compensation terms, and the corporation's response to the conduct may determine whether the defendant acted as the company or as an outside participant.

Prospective Relationships Require an Independent Wrong

A prospective relationship claim protects a transaction that probably would have occurred. Under Coinmach Corp. v. Aspenwood Apartment Corp., 417 S.W.3d 909 (Tex. 2013), the claimant must prove a reasonable probability of a business relationship, intentional interference, independently tortious or unlawful conduct, proximate cause, and damage.

Probability requires more than general hope for future business. Negotiations, draft terms, customer communications, purchase history, internal approval, committed financing, and testimony from the prospective counterparty may show that the transaction probably would have occurred. A broad market opportunity or an unidentified group of possible customers rarely supplies the same proof.

The independent wrong element separates this claim from lawful competition. Wal-Mart Stores, Inc. v. Sturges, 52 S.W.3d 711 (Tex. 2001), held that sharp or unfair conduct alone is insufficient. Fraudulent statements, defamation, threats amounting to an actionable tort, an illegal boycott, trespass, or trade secret misappropriation may qualify.

A contract breach by itself isn't the kind of independent tort or statutory wrong Sturges requires. A restrictive covenant may affect the dispute, but alleging its breach doesn't automatically establish prospective interference. The claimant must identify conduct actionable under a recognized tort or prohibited by statute.

The claimant needn't recover separately on the predicate wrong in every case. Sturges requires conduct that would be actionable under a recognized tort, while allowing the defendant to assert any defense applicable to that underlying wrong.

Justification Differs Between the Two Claims

Justification serves as an affirmative defense to interference with an existing contract. Prudential Insurance Co. of America v. Financial Review Services, Inc., 29 S.W.3d 74 (Tex. 2000), recognizes justification when a defendant exercises a legal right or a good faith claim to a colorable legal right. Motive doesn't defeat a defense based on an established legal right.

A colorable right requires a legal interest that could support the conduct, followed by proof that the defendant asserted it in good faith. Fraud, misrepresentation, or another tort used to interfere can defeat justification because the defendant has no protected right to use unlawful means.

Prospective relationship claims treat the issue differently. Sturges placed privilege and justification within the claimant's required proof of an independent wrong and the defenses to that wrong. A defendant accused of defamation may assert truth or privilege as a defense to defamation. Texas law supplies no separate justification defense after the claimant proves every element of prospective interference.

Lawful competition commonly defeats the prospective claim because offering a lower price, better service, or stronger terms supplies no independent wrong. Existing contracts require closer attention to the promises already in force. Competition alone doesn't authorize a defendant to induce violation of a binding contractual right.

Damages Depend on Causation and Proof

Damages compensate for the economic interest the interference injured. An existing contract claim may support recovery for the lost benefit of the agreement and foreseeable consequential loss caused by the interference. A prospective relationship claim requires proof of the value of the transaction that probably would have occurred.

Lost profit evidence must establish the amount with reasonable certainty. In Horizon Health Corp. v. Acadia Healthcare Co., 520 S.W.3d 848 (Tex. 2017), the Supreme Court required evidence connecting claimed future business to identified customers and probable transactions. Market size, optimistic projections, or the defendant's revenue can serve as evidence, but none automatically measures the claimant's loss.

Texas law provides no general rule allowing the claimant to recover the defendant's gain as the measure of tortious interference damages. A separate fiduciary, trade secret, or equitable claim may support disgorgement when its elements are satisfied. Keeping each damages theory tied to its cause of action avoids a request for relief the interference tort doesn't supply.

Exemplary damages require proof of fraud, malice, or gross negligence under the heightened evidentiary standard in Civil Practice and Remedies Code Section 41.003. Section 41.008 generally caps the award through its statutory formula. Tortious interference also supplies no independent right to attorney fees, though another contract or statute may authorize them for a separate claim.

The Two Year Period Begins With Known Injury

Civil Practice and Remedies Code Section 16.003(a) sets a two year limitations period for tortious interference. Exxon Mobil Corp. v. Rincones, 520 S.W.3d 572 (Tex. 2017), held that the claim accrues when the claimant knows the nature of the injury and the resulting damage, even if the contract ends on a subsequent date.

Continuing economic loss doesn't restart the filing period. Once the claimant knows the interference caused an injury, later invoices, lost payments, or termination may increase damages without creating a new accrual date. Fraudulent concealment can suspend limitations under a separate equitable doctrine when its requirements are proven, but it doesn't supply a general discovery rule for every concealed interference claim.

Evidence Should Match the Claim

Your first case assessment should identify the agreement, the exact right affected, the person who acted, and the communication that caused the contracting party's response. For a prospective transaction, the evidence should also identify the expected counterparty, the probability of agreement, and the independent tort or unlawful act.

Document preservation should cover contract versions, amendments, termination notices, customer communications, internal messages, pricing records, proposal drafts, approval materials, and evidence of the defendant's knowledge. Damages records should distinguish lost contract benefits from speculative future sales and from relief available only under another claim.

A strong interference theory explains the sequence without relying on labels. It identifies a protected right or probable transaction, shows why the defendant's conduct was intentional and legally wrongful, and connects that conduct to the lost economic interest. It also supports a filing within two years of the known injury.
