Offer and acceptance

Offer and acceptance analysis is a traditional approach in contract law used to determine whether an agreement exists between two parties. An offer is an indication by one person ("offeror") to another ("offeree") of the offeror's willingness to contract on certain terms without further negotiations. A contract is then formed if there is express or implied agreement. A contract is said to come into existence when acceptance of an offer has been communicated to the offeror by the offeree.
