Civil Conspiracy and Knowing Participation in Another's Fraud or Breach

Why these claims matter

The person who committed the fraud is often the least collectible defendant. The money went to a spouse, a new company, a business partner who looked the other way, or a professional who processed the transactions. Civil conspiracy and knowing participation are how Texas law reaches those people. Each makes a helper liable for the full damages of the wrong, not just the share they received.

Civil conspiracy: the elements

Texas courts describe civil conspiracy with five elements: two or more persons; an object to be accomplished; a meeting of the minds on the object or course of action; one or more unlawful, overt acts; and damages as the proximate result. The meeting of the minds requires specific intent: the participants must have agreed to accomplish an unlawful purpose, or a lawful purpose by unlawful means, and must have known the object was wrongful. Negligence does not make a conspirator. A person who unknowingly helped, however carelessly, is not liable under this theory.

Agreement is almost never proven by a signed pact. It is inferred from conduct: coordinated timing, shared accounts, communications that assume a plan, participation in steps that make no sense without one. Texas courts allow the inference but require more than parallel conduct or association.

Not an independent claim: Agar v. Electro Circuits

In Agar Corp. v. Electro Circuits International (Tex. 2019) the Texas Supreme Court settled two questions that had divided lower courts. First, civil conspiracy is not an independent tort. It is a theory of vicarious liability: a way to make each conspirator responsible for the damages caused by the underlying tort committed in furtherance of the conspiracy. Without a viable underlying tort, such as fraud, conversion, breach of fiduciary duty or tortious interference, there is no conspiracy claim. Second, because it is derivative, conspiracy has no limitations period of its own. It takes the limitations period of the underlying tort. A conspiracy to commit fraud is governed by the four-year fraud period; a conspiracy to convert property by the two-year conversion period.

Three practical consequences follow:

• A plaintiff must plead and prove the underlying tort against at least one participant. If the fraud claim fails, the conspiracy claim fails with it.
• A defendant who did not personally make the false statement or take the property can still be liable for all of the damages, if the plaintiff proves the agreement and that defendant's knowledge of the wrongful object.
• A conspiracy label cannot extend a deadline. If the underlying conversion claim is time-barred, calling it a conspiracy does not revive it.

The underlying torts in business cases are usually fraud, whose elements are covered in how to prove fraud in a Texas business dispute, and breach of fiduciary duty.

Who can conspire

A conspiracy needs two or more persons. Texas courts generally hold that a corporation cannot conspire with itself, so a company and its own officers or employees, acting within their roles, are usually treated as one actor; the intracorporate doctrine has exceptions where an agent acts for a personal purpose outside the corporate interest. Two separate companies, a company and an outside vendor, a partner and their spouse, or a departing employee and a competitor can all form a conspiracy. The question in each case is whether the second person agreed to the wrongful object with knowledge of it.

Knowing participation in a breach of fiduciary duty

This doctrine predates and operates alongside conspiracy. In Kinzbach Tool Co. v. Corbett-Wallace Corp. (Tex. 1942) the Texas Supreme Court held that a third party who knowingly participates in a fiduciary's breach of duty becomes a joint tortfeasor with the fiduciary and is liable as such. The court applied it to a company that paid a secret commission to the other side's employee to secure a sale; the company knew the employee was the buyer's agent and knew he had not disclosed the commission.

Texas courts of appeals state the elements as: a fiduciary relationship existed between the plaintiff and the fiduciary; the third party knew of the fiduciary relationship; and the third party was aware that it was participating in the fiduciary's breach. No agreement needs to be proven, which is why knowing participation is often easier to establish than conspiracy. What must be shown is knowledge: of the relationship and of the breach. A bank that processes a wire is not a knowing participant; a bank officer who structures the transfer to hide it from the other partners may be.

Who owes fiduciary duties in the first place is explained in who owes a fiduciary duty in a Texas business. The remedies against a knowing participant include the same equitable relief available against the fiduciary, including disgorgement of what the participant gained.

Example

Suppose the managing member of a Dallas restaurant group diverts the group's catering contracts to a new LLC owned by his brother-in-law, who runs the catering using the group's staff and recipes and splits the profit with him. The other members sue the manager for breach of fiduciary duty. They also sue the brother-in-law. The conspiracy theory requires proof that the two agreed to divert the business and that the brother-in-law knew it was wrongful; the text messages planning which contracts to move supply that. The knowing participation theory requires only that the brother-in-law knew the manager was a fiduciary of the group and knew the diversion breached that duty; his role as a former investor in the group supplies the first, and the secrecy of the arrangement supports the second. Under either theory he is liable for the group's lost profits, and the court can order him to disgorge his share.

Aiding and abetting: not settled in Texas

Plaintiffs sometimes plead "aiding and abetting" fraud as a separate claim. The Texas Supreme Court has repeatedly declined to say whether Texas recognizes such a claim, most recently in First United Pentecostal Church of Beaumont v. Parker (Tex. 2017), where it decided the case without reaching the question. Until the court adopts it, a claim styled as aiding and abetting is vulnerable to dismissal, and plaintiffs are better served pleading conspiracy and knowing participation, which are established. In the securities context, by contrast, the Texas Securities Act expressly imposes liability on aiders with the required awareness; that statutory claim is covered in control person and aider liability under the Texas Securities Act.

Joint and several liability and proportionate responsibility

A conspirator or knowing participant is liable for the whole of the damages caused by the underlying tort, not just their share. Texas's proportionate responsibility statute, chapter 33 of the Civil Practice and Remedies Code, otherwise limits a defendant's liability to its percentage of responsibility unless that percentage exceeds 50 percent, but it preserves joint and several liability for defendants who acted with specific intent to do harm and committed certain listed felonies, including theft and misapplication of fiduciary property above felony thresholds. How chapter 33 applies to a particular conspiracy claim depends on the underlying tort and the jury's findings, and it is a point on which the defense will press hard.

Defending a conspiracy or participation claim

The defenses track the elements. No underlying tort, no conspiracy. No knowledge of the wrongful object, no conspiracy; good-faith participation in a transaction that turned out to be part of a fraud is not enough. No knowledge of the fiduciary relationship or of the breach, no knowing participation. Intracorporate conduct, no second person. And limitations: the underlying tort's period applies, and a late-added conspiracy count cannot cure a late underlying claim. Defendants who are professionals or lenders also look to their engagement terms and to the proportionate responsibility statute to confine their exposure.

Evidence and deadlines

These claims are won on communications between the participants: messages, emails, shared calendars, bank records showing the flow between them. Early subpoenas to the recipients of the money, and preservation demands to each participant, matter more than in a two-party fraud case. The deadline is the underlying tort's: four years for fraud and breach of fiduciary duty, two for conversion, subject to the discovery rule where the wrong was concealed.
