An offer must be communicated to the offeree to be valid. The communication of the offerer's intentions may be by whatever means is convenient and desirable. It may be communicated orally or by letter, telegram, or any other means capable of transmitting the offerer's proposal. It may also be implied. Acts and conduct of the proposing party are, in many cases, successful in communicating an intention to make an offer to another party witnessing them. When acts and conduct are sufficient to convey an offerer's intentions, an implied offer results.
At times, an offer must be communicated to a party whose name, identity, or address is unknown. In such cases, a public offer is made. A public offer is made through the public media but is intended for only one person whose identity or address is unknown to the offerer. The classic example of a public offer is an advertisement in a lost-and-found column in a newspaper.
By contrast, invitations to trade are not offers. An invitation to trade is an announcement published for the purpose of creating interest and attracting a response by many people. Newspaper and magazine advertisements, radio and television commercials, store window displays, price tags on merchandise, and prices in catalogs are included within this definition. In the case of an invitation to trade, no binding agreement develops until a responding party makes an offer that the advertiser accepts.
The second major element in a binding contract is acceptance of the offer. An acceptance means that the offeree agrees to be bound by the terms set up by the offerer in the offer. Only the offeree, the one to whom the offer is made, has the right to accept an offer. If another party attempts to accept, that attempt would actually be a new and independent offer.
Unilateral contracts do not usually require oral or written communication of an acceptance. When the offerer makes a promise in a unilateral contract, the offerer expects an action, not another promise in return. Performance of the action requested within the time allowed by the offerer and with the offerer's knowledge creates the contract.
In bilateral contracts, unlike unilateral ones, the offeree must communicate acceptance to the offerer. Bilateral contracts consist of a promise by one party in return for a promise by the other. Until the offeree communicates a willingness to be bound by a promise, there is no valid acceptance.
An offer may be accepted by either express or implied means of communication. In an express acceptance, the offeree may choose any method of acceptance, unless the offer states that it must be made in a particular manner. A stipulation such as «reply by Federal Express» or «reply by certified mail» in the offer must be carried out to complete an acceptance.
To be effective, an acceptance must be unequivocal, which means that the acceptance must not change any of the terms stated in the offer. Under common law, this stipulation is known as the mirror image rule.
Under the mirror image rule, the terms stated in the acceptance must duplicate the terms in the offer. If the acceptance changes or qualifies the terms in the offer, it is not an acceptance but a counteroffer. A counteroffer is a response to an offer in which the terms of the original offer are changed. No agreement is reached unless the counteroffer is accepted by the original offerer.
In contracts for the sale of goods, as long as there is a definite expression of acceptance, a contract will result even though an acceptance has different or additional terms. If both parties are not merchants, the different or additional terms are treated as proposals for amendment to the contract. If the parties are both merchants, however, the different or additional terms become part of the contract unless (a) they make an important difference, (b) the offerer objects, or (c) the offerer limits acceptance to its terms.
Acceptance may result from the conduct of the offeree. Actions and gestures may indicate the offeree's willingness to enter into a binding agreement.
As a general rule, silence is not an acceptance. If, however, both parties agree that silence on the part of the offeree will signal acceptance, then such an acceptance is valid.
Another exception to the general rule occurs when the offeree has allowed silence to act as acceptance. The offerer cannot force the offeree into a contract by saying silence will mean acceptance. The offeree, however, can force the offerer into a contract if the offerer established the silence condition.
A rejection comes about when an offeree expresses or implies refusal to accept an offer. Rejection terminates an offer and all negotiations associated with it. Further negotiations could commence with a new offer by either party or a renewal of the original offer by the offerer. Rejection is usually achieved when communicated by the offeree.
A revocation is the calling back of the offer by the offerer. With the exception of an option contract and a firm offer, an offer may be revoked anytime before it has been accepted. The offerer has this right, despite what might appear to be a emphasis moral obligation to continue the offer. An offer may be revoked by communication, automatic revocation, passage of time, death or insanity of the offerer, destruction of the subject matter, or the subsequent illegality of the contract.
An offer may be revoked by the offerer communicating that intention to the offeree before the offer has been accepted. Revocation is ineffective if the acceptance has already been communicated, as by mailing the acceptance in response to a mailed offer. Direct communication of revocation is not required if the offeree knows about the offer's withdrawal by other means.
When the terms of an offer include a definite time limit for acceptance, the offer is automatically revoked at the expiration of the time stated.
An option contract is an agreement that binds an offerer to hold open an offer for a predetermined or reasonable length of time. In return for this agreement to hold the offer open, the offerer receives money or something else of value from the offeree. Parties to an option contract often agree that the consideration may be credited toward any indebtedness incurred by the offeree in the event that the offer is accepted. Should the offeree fail to take up the option, however, the offerer is under no legal obligation to return the consideration.
Option contracts remove the possibility of revocation through death or insanity of the offerer. The offeree who holds an option contract may demand acceptance by giving written notice of acceptance to the executor or administrator of the deceased offerer's estate or to the offerer's legally appointed guardian.
A special rule has emerged in international law. This rule holds that no consideration is necessary when a merchant agrees in writing to hold an offer open. This is called a firm offer.
