Civil Conspiracy Under Texas Law

By Melissa J. Parker · Last updated July 15, 2026

Texas civil conspiracy is a derivative claim. It cannot exist on its own. Without an underlying tort that the conspirators agreed to commit, the conspiracy claim has no foundation. But when an underlying tort is present and multiple parties participated in or facilitated it, the conspiracy theory expands liability to reach every participant, even those who did not personally commit each element of the underlying tort.

The fight is almost always over who else pays. The principal actor who committed the fraud may be judgment-proof. But the financier who funded the scheme and the adviser who helped structure it have assets and reachable identities, and so does the silent partner who shared in the profits. In business litigation, the conspiracy claim is the tool that pulls them into the case.

The five elements

Texas courts have consistently applied a five-element framework:

Two or more persons. Conspiracy requires multiple actors. A single defendant cannot be liable for conspiracy alone. The multiple-actor element is the threshold requirement that distinguishes conspiracy from individual tort liability.

An object to be accomplished. The conspirators must have shared a common object, the goal of the conspiracy. The object must be the commission of a specific tort or unlawful act, not merely some general business objective.

A meeting of the minds on the object. The conspirators must have agreed on the object. The agreement does not need to be formal or explicit; it can be inferred from conduct. But there must be evidence that the participants understood and accepted the common purpose.

One or more unlawful overt acts in furtherance. At least one conspirator must have taken an overt act to accomplish the object. The act must be unlawful, typically the underlying tort itself or an act in direct furtherance of it.

Damages as a proximate result. The plaintiff must have suffered concrete damages from the conspiracy.

The “unlawful” element is what makes conspiracy a derivative claim. Texas has consistently held that the unlawful overt act must constitute an actionable underlying tort. Without an underlying tort, the conspiracy fails as a matter of law.

The underlying tort requirement

The Texas Supreme Court has been clear: civil conspiracy is not a stand-alone tort. The plaintiff must identify an actionable underlying tort that the conspirators agreed to commit. If the underlying tort cannot be sustained, because elements are missing, because affirmative defenses succeed, because limitations have run, the conspiracy claim falls with it.

Common underlying torts in business conspiracy cases:

• Fraud and fraudulent inducement. See Fraud and Fraudulent Inducement.
• Tortious interference with contract. See Tortious Interference with Contract.
• Breach of fiduciary duty (by the breaching fiduciary; the conspiracy reaches the third parties who participated).
• Civil theft under the Texas Theft Liability Act. See Civil Claims Under the Texas Theft Liability Act.
• Trade secret misappropriation. See Trade Secret Misappropriation Under TUTSA.
• Fraudulent transfer.

The structure of the case usually involves a primary actor and one or more secondary actors. The primary actor is the direct participant, the one who committed the fraud, breached the fiduciary duty, or accomplished the misappropriation. The secondary actors are the conspirators. They facilitated, financed, advised, or shared in the proceeds.

Proving the meeting of the minds

Conspiracy plaintiffs rarely have direct evidence of an agreement. The conspirators do not generally document their plans in writing. The meeting of the minds element is typically established through circumstantial evidence.

What circumstantial evidence supports the meeting of the minds:

Coordinated conduct. Actions by multiple parties that align in timing, manner, and purpose in ways that imply prior agreement.

Financial connections. Money flows between the conspirators that link them to the tort and its proceeds.

Communications. Email, text messages, or other communications that establish the parties were exchanging information about the underlying conduct.

Common purpose. Evidence that the conspirators stood to benefit from the conduct and acted in pursuit of that benefit.

Concert of action. Patterns showing that multiple parties acted in coordinated ways at critical moments.

Discovery in conspiracy cases focuses heavily on developing this circumstantial record. Bank records, email accounts, phone records, calendar entries, and similar documentary evidence are central to the case. The actual conspiracy agreement is almost never found in any single document. The case is built from the pattern.

Joint and several liability

When conspiracy is proven, the conspirators are jointly and severally liable for the damages caused by the underlying tort. This is the practical reason for pleading conspiracy:

• The plaintiff can recover the full damages from any conspirator, leaving the conspirators to sort out contribution among themselves.
• A judgment-proof primary actor is not the end of the case if conspirators with assets participated.
• Settlement leverage increases substantially when multiple defendants face full liability exposure.

Joint and several liability under Chapter 33 of the Civil Practice and Remedies Code is subject to specific allocation rules. Conspirators found responsible for the underlying tort can be held jointly and severally liable in many but not all circumstances. The proportionate responsibility framework sometimes limits the joint and several exposure.

Defenses to civil conspiracy claims

The most common defenses:

No underlying tort. Attack the underlying claim. If the fraud claim fails, the conspiracy to commit fraud fails with it. Most conspiracy defenses run through attacks on the underlying tort.

No agreement. Attack the meeting of the minds element. The defendant may have engaged in conduct that paralleled other conspirators but did not actually agree with them on the object. Parallel conduct without agreement is not conspiracy.

No knowledge of the tortious purpose. A defendant who participated in conduct without knowing it was tortious is not a conspirator. The defendant must have known of the unlawful object and agreed to it.

No participation in the unlawful act. A defendant who knew about the unlawful conduct but did not participate or agree to participate is not a conspirator. Mere knowledge is not enough.

Statute of limitations. Texas applies the limitations period of the underlying tort to the conspiracy claim. Most underlying torts have two- or four-year periods.

Strategic uses of the conspiracy claim

The conspiracy claim is most valuable in three categories of cases:

Fraud cases with financial backers. When the primary fraudster is judgment-proof but received funding, professional services, or shared proceeds with parties that have assets, the conspiracy theory reaches those backers.

Business divorce cases with concerted action. When co-owners have conspired to push out a fellow owner, through diverted opportunities, suppressed information, or coordinated transactions conspiracy can be pleaded alongside breach of fiduciary duty to expand recovery.

Asset hiding cases. When debtors conspire with family members, related entities, or third parties to move assets out of reach, conspiracy expands fraudulent transfer recovery to the transferees and other participants.

The challenge in each context is proving the meeting of the minds. Strong cases have documentary evidence of coordination. Weak cases rest on inferences from parallel conduct, which usually does not survive summary judgment.

When the conspiracy case connects to other claims

Civil conspiracy is by nature combined with other claims. Common combinations:

• Fraud plus conspiracy to commit fraud. See Fraud and Fraudulent Inducement.
• Tortious interference plus conspiracy. See Tortious Interference with Contract.
• Breach of fiduciary duty plus conspiracy by third-party participants.
• Trade secret misappropriation plus conspiracy reaching beneficiaries of the misappropriation.

Conspiracy is the connective tissue that ties together the participants in a multi-actor tort case.

No meeting of the minds, no conspiracy

We plead conspiracy only when there is a real basis for the meeting of the minds. Pleading it without evidence invites Rule 91a motions and burns pleading credibility. We then build the circumstantial record through targeted discovery, bank records, email accounts, and communications among the alleged conspirators are the foundation of most conspiracy proofs. We work the underlying tort and the conspiracy together, because they stand or fall together, and each conspiracy theory has to be tied to a specific underlying tort we can prove.

Conspiracy buys nothing on its own. Its leverage comes entirely from the underlying tort and the second defendant it reaches. Get the underlying tort right and prove a genuine agreement, and the claim turns a judgment-proof defendant into a collectible one. Plead it loosely, and it is the first thing the other side moves to strike.
