Promissory Estoppel Rule
A promise which the promisor should reasonably expect to induce action or forbearance on the part of the promisee or a third person and which does induce such action or forbearance is binding if injustice can be avoided only by enforcement of the promise. The remedy granted for breach may be limited as justice requires.
The obligor is the party who owes an obligation (i.e., a legal duty) to the obligee.
The obligee is the party who has a legal right to receive the benefit of the legal duty owed.

a promise to do or not to do something without the expectation of anything of legal value in return.
