There are four ways to determine whether the rights of the third-party beneficiary are unshakable: a third-party clause determines whether a non-contractual party has the right to enforce the contractual terms. Sometimes beneficiaries are named, and sometimes they receive rewards by chance. On the agreed date, the dealer does not deliver the car. Robert discovers that the new car was never ordered. In this case, Everett was able to show that he knew how much he would benefit from the contract and whether he relied on that belief to sell his old car. Being aware of the new car, he is a third party beneficiary with the right to enforce the agreement against the car dealer. However, there are many situations where an agreement is beneficial and aims to confer rights on third parties.
