A third-party beneficiary entitled to enforce a contract must be explicitly mentioned or implied as intended to benefit from the agreement by the contracting parties. Incidental beneficiaries, on the other hand, gain no enforcement rights because they benefit by chance and not by the clear directional intent of the contracting parties.
For example: If a musician contracts with a venue for a concert mainly to entertain fans (third-party beneficiaries), they can claim damages if the concert is canceled without cause. However, if a nearby parking garage incidentally profits from the event, they cannot claim lost revenue as they are incidental beneficiaries.
