Legal Definition
The promisor is the person making the promise that benefits a third party (i.e., the person who gives his performance—payment—to the third party).
Plain English Explanation
A promisor is the person who makes a promise in a contract that benefits a third party. In other words, the promisor is the one agreeing to do something (like paying money or providing a service) that will benefit someone else who isn’t part of the contract.
For example, if Bob promises to pay Sam $500 to mow Amy’s lawn, Bob is the promisor, Sam is the one receiving the payment, and Amy is the third-party beneficiary.
The promisor (Bob) is responsible for fulfilling the promise, even though the benefit (mowing Amy's lawn) directly helps the third party (Amy).
For example, if Bob promises to pay Sam $500 to mow Amy’s lawn, Bob is the promisor, Sam is the one receiving the payment, and Amy is the third-party beneficiary.
The promisor (Bob) is responsible for fulfilling the promise, even though the benefit (mowing Amy's lawn) directly helps the third party (Amy).
Hypothetical
Hypo 1: Bob offers Sam $100 to paint Amy's house. Sam agrees. Result: Bob is obligated to pay Sam $100, and Sam is obligated to paint Amy's house. Here, Bob is the promisee and Sam is the promisor. They are both parties to the contract. Amy is a third-party beneficiary of the contract.
