Understanding Collateral Contracts

Collateral contracts are formed concurrently with the main contract. They are usually precipitated by statements or assurances given by one party, aiming to induce the other into entering the main contract. The essence of a collateral contract is its ability to provide a legal remedy should these statements or assurances prove false or misleading.

Direct & Third Party Collateral Contracts

Direct Collateral Contracts: Here, a statement made by the promisor to the promisee forms a separate contract parallel to the main contract between the same parties.

Third-Party Collateral Contracts: In this scenario, the promisor makes a statement to the promisee, following which the promisee enters into a contract with a third party. The statement then forms a contract between the promisor and promisee, collateral to the main contract with the third party.


Elements of Collateral Contract Formation


For a collateral contract to be established, three core circumstances are often present:

Intention to Rely: The maker of the statement intends for the statement to be relied upon.


Actual Reliance: The party alleging the existence of the collateral contract has indeed relied on the statement.


Guarantee of Truth: The maker of the statement intends to guarantee its truth (or falsity).

Consistency: A vital aspect of collateral contracts is the requirement of consistency. A collateral contract cannot contradict the terms or undermine the essence of the main contract. This requirement ensures that the collateral contract doesn’t overshadow or alter the fundamental premises of the main contract. However, this requirement of consistency is not applicable in cases of collateral contracts with a third party.


Notably, the third element is crucial as it distinguishes collateral contracts from mere representations or opinions. Furthermore, the timing of the statement in relation to the formation of the main contract is pivotal; a collateral contract cannot be inferred if the main contract was agreed upon before the making of the statement.

Engaging with Third Parties

Collateral contracts with third parties follow the same fundamental principles, with the cornerstone being the intention to guarantee the truth of a statement or a promissory undertaking. The absence of a consistency requirement in third-party collateral contracts provides a nuanced difference, allowing for broader contractual dynamics.

Collateral Contract Examples

Creating a collateral contract involves a separate agreement that's formed alongside a main contract. The formation of a collateral contract often hinges on statements or promises that are made to induce another party into entering the main contract. Here are simplified examples to elucidate the concept of collateral contracts, both directly and with third parties:

Direct Collateral Contract Example

Suppose you wish to buy a car from a dealer. The dealer, to entice you into making the purchase, promises to provide free servicing for the car for the first two years. You agree to buy the car based on this promise. Here, two contracts are formed:

Main Contract: The sale and purchase agreement of the car.

Collateral Contract: The dealer's promise to provide free servicing for the first two years.

Third-Party Collateral Contract Example

John is interested in purchasing a piece of land but is hesitant due to the financial commitment. His wealthy friend, Mark, encourages him to buy the land. Mark promises John that if he goes ahead with the purchase, Mark will buy the land from him at a 25% increased price within the next six months. Trusting Mark's promise, John buys the land.

In this situation, a third-party collateral contract is formed between John and Mark. The main contract is the purchase of land between John and the land seller. The collateral contract is Mark's promise to buy the land from John at a 25% increased price. The consideration for the collateral contract is the entering into the main contract (the purchase of the land).

The elements for establishing a collateral contract are present:


Intention to Rely: John relied on Mark's promise when deciding to purchase the land.


Intention to be Legally Bound: Mark intended to be legally bound by his promise.


Consideration: The consideration for the collateral contract is the entering into the main contract (the purchase of the land) by John based on Mark's promise.

This collateral contract allows John to have a safety net, ensuring he won't suffer financial loss from the land purchase, while Mark's intention might be to encourage land ownership or to secure the land for future use.
