CAN A PERSON WHO DID NOT SIGN THE CONTRACT BE HELD LIABLE FOR ITS BREACH?

The liability of a third party who deliberately interferes with a contractual relationship

As a general rule, a contract creates rights and obligations between the persons who entered into it.

This rule may create the impression that anyone who did not sign the document can never be held liable for losses caused to the transaction.

The legal reality is more complex.

Under certain circumstances, a third party who is aware of the existence of a contract and deliberately interferes with its performance may be held liable for the resulting damage.

This may occur when someone induces one of the parties to abandon the transaction, diverts an operation that was already committed, participates in a scheme intended to prevent performance of the obligation, or knowingly benefits from the contractual breach.

The central issue is not merely determining who signed the contract.

It is necessary to understand who effectively contributed to its breach.

A contract does not create unlimited obligations for third parties

A third party who did not participate in the contract does not automatically become liable for its provisions.

They cannot be treated as a debtor merely because they were aware of the contractual relationship or entered into another transaction with one of the parties.

Freedom of contract, competition, and the circulation of goods and services remain protected.

For this reason, it is not enough to demonstrate that the third party obtained an advantage or that their conduct coincided with the termination of the contract.

Potential liability requires the examination of more specific elements, such as:

• knowledge of the contractual relationship;

• conduct that effectively interfered with it;

• intent or conduct contrary to good faith;

• contribution to the breach;

• the existence of damage;

• a causal relationship between the interference and the resulting loss.

Liability does not arise merely from the presence of a third party.

It arises from the manner in which that third party acts in relation to a legal relationship they know exists.

When may interference become unlawful?

Interference may become legally relevant when it exceeds the normal limits of freedom of negotiation and improperly compromises the performance of an existing contract.

Consider a company that knows a particular professional has undertaken an exclusivity obligation with a competitor.

Even so, it offers a specific advantage to persuade that professional to abandon the commitment immediately, using inside information and causing the interruption of an ongoing project.

In another situation, a purchaser becomes aware that a particular property has already been promised to another person but structures the transaction with the seller to exclude the first purchaser and prevent completion of the earlier transaction.

An intermediary may also divert a negotiation, conceal offers, alter information, or induce one of the parties to terminate the contract in order to obtain a commission or personal advantage.

In such circumstances, the dispute is not limited to the breach committed by the person who signed the contract.

It may also extend to the third party who knowingly participated in the violation.

Does merely making a better offer create liability?

Not every more advantageous offer constitutes unlawful interference.

Business activity necessarily involves competition, negotiation, and the pursuit of better opportunities.

A company may hire a supplier that previously served another client.

A professional may lawfully terminate one relationship and accept a new offer.

An owner may negotiate their property after a prior commitment has been properly terminated.

The problem arises when the new transaction depends on the deliberate violation of an existing obligation.

There is a difference between competing for an available business opportunity and causing the improper termination of a known contract.

There is also a difference between presenting a legitimate offer and participating in a strategy intended to conceal assets, divert revenue, frustrate a transaction, or prevent performance of an assumed obligation.

The boundary between legitimate competition and unlawful interference depends on the specific circumstances.

Is knowledge of the contract sufficient?

Knowledge of the contract is an important element, but it is not necessarily sufficient.

A person may know that a contractual relationship exists and still act lawfully.

Liability requires more than general awareness.

It is necessary to examine whether the third party:

• knew of the relevant obligation;

• understood that their conduct could cause a breach;

• encouraged or facilitated the termination;

• collaborated in concealment or sham arrangements;

• received an advantage directly connected to the violation;

• acted in a manner incompatible with the loyalty expected in legal relationships.

Evidence of this participation is often one of the most sensitive aspects of the dispute.

There is rarely a document in which the third party expressly acknowledges an intention to harm the contractual relationship.

The analysis may depend on messages, offers, meetings, financial transfers, the sequence of events, personal or business relationships, and the subsequent conduct of those involved.

Is the third party liable under the contract itself?

The potential liability of a third party does not mean that they automatically assume the position of the defaulting contracting party.

As a general rule, they will not be required to perform an obligation they never assumed.

Their liability arises from conduct directed against the contractual relationship, rather than from their status as a contracting party.

For this reason, the consequence may involve compensation for the damage caused by their interference.

Depending on the circumstances, the dispute may involve:

• direct financial losses;

• expenses incurred in performing the transaction;

• loss of revenue;

• interruption of activities;

• diversion of clients;

• disruption of a business operation;

• loss of a concrete opportunity;

• damage to the organization or reputation of the business.

The extent of liability will depend on the conduct involved, proof of the damage, and the connection between the interference and the resulting loss.

Is the party that breached the contract released from liability?

The participation of a third party does not, by itself, eliminate the liability of the person who assumed the contractual obligation.

The party that breached the contract may remain liable for non-performance.

The third party may also be held liable for their own conduct when it is demonstrated that they improperly contributed to the damage.

These forms of liability may have different legal grounds.

One arises from the obligation assumed under the contract.

The other arises from unlawful interference with another person’s legal relationship.

In certain situations, the conduct may be so closely connected that the assessment must consider the joint actions of those involved.

Interference may occur within the company itself

The third party is not always an external competitor or purchaser.

Interference may originate from persons closely connected to the contractual relationship, such as:

• a partner who did not sign the transaction;

• a manager without formal authority;

• a company belonging to the same corporate group;

• a family member of one of the parties;

• a broker or intermediary;

• a consultant involved in the transaction;

• a person used to receive funds or acquire the asset;

• a new company created to continue the activity.

The existence of a personal or business connection does not automatically create liability.

However, such proximity may be relevant when the third party participates in the decision, knows of the obligations undertaken, and contributes to preventing their performance.

The use of another person or company to formally avoid the effects of the contract does not prevent the actual circumstances of the transaction from being examined.

Documentation of the transaction makes a difference

Contractual protection does not depend solely on the wording of the document.

It also requires the organization and preservation of evidence demonstrating the conduct of the parties and any third parties involved.

In significant transactions, it is prudent to preserve:

• offers and counteroffers;

• messages and correspondence;

• meeting minutes;

• exclusivity records;

• proof of payment;

• communications concerning termination;

• documents demonstrating the third party’s knowledge;

• evidence indicating diversion of the transaction;

• records of the resulting losses.

A well-drafted contract is essential, but it may not be sufficient when the entire negotiation takes place informally.

The absence of documentation allows the interference to be presented as a mere coincidence, a change of interest, or the lawful exercise of freedom of contract.

Not every loss results from unlawful interference

A contract may be terminated for several reasons.

One of the parties may have failed to perform their own obligations.

The transaction may have become unfeasible.

The contract may contain a clause authorizing termination.

The subsequent transaction may have occurred only after the prior relationship was properly concluded.

It is also possible that the third party was unaware of the contract or had no intention of interfering with its performance.

For this reason, liability should not be based solely on the existence of a loss.

It is necessary to reconstruct the sequence of events and distinguish between:

• contractual non-performance;

• legitimate competition;

• the independent decision of one of the parties;

• the knowing participation of third parties;

• the damage actually resulting from each act.

This distinction prevents every subsequent negotiation from being treated as unlawful conduct.

Conclusion

The fact that a person did not sign the contract does not mean that their conduct is legally irrelevant.

Freedom of contract and competition must be preserved.

However, such freedom does not authorize deliberate interference with a known contractual relationship, particularly when a third party induces non-performance, participates in a scheme, or knowingly benefits from a violation.

Liability will depend on proof of knowledge, conduct, damage, and the connection between the interference and the resulting loss.

The strategic question is not merely:

Who failed to perform the contract?

It is also necessary to investigate:

Who participated in the breach, how did they benefit, and what was their contribution to the outcome?

In significant transactions, understanding the conduct of everyone involved may reveal that the dispute is not limited to the persons identified in the contractual instrument.
