I've read many English law judgments, and I always see Offeree/Offeror and Promisee/Promisor. I rarely see Obligee/Obligor. But aren't these pairs superfluous? How can they be distinguished?


If you're a promisee, you must've have been an offerree because you must have accepted the offer that you received! Similarly, if you're a promisor, you must've been the offeror!


Above, Obligee/Obligor and Promisee/Promisor are identical except for "promissory" in the definition for Promisee/Promisor.



Offerror/Offeree vs. Promisee/Promisor?
