Final answer:
In contract law, when an offeror specifies the exact details of how an offer must be accepted, it is known as express stipulation. Acceptance must fulfill these terms to be valid, and deviations can lead to the offer not being accepted.
Step-by-step explanation:
When the offeror, as the master of the offer, specifies the precise time, place, and manner in which acceptance must be communicated, it is termed as express stipulation. In contract law, the offeror has the right to dictate the conditions of an offer, including how an offer must be accepted
If these conditions are not met, there may be no legally enforceable agreement. For instance, if an offeror requires that acceptance be delivered by mail to a specified address by a certain date, acceptance is only valid if it complies with those terms. Any deviation from the stipulated manner of acceptance may result in the offer being deemed as not accepted.
