According to the law, a contract is formed when one party communicates an offer and the other party communicates acceptance and valuable consideration passes between the contracting parties.
To prove a valid offer, a party must show (a) the offeror intended to make an offer, (b) the terms of the offer were clear and definite, and (c) the offeror communicated the essential terms of the offer to the offeree. For there to be an offer that may ripen into a contract by simple acceptance, the offer must be reasonably definite in its terms and must sufficiently address the essentials of the proposed transaction that, with an expression of assent, there will be a complete and definite agreement on all essential details. Most offers can be revoked at any time before acceptance. The only exception to this rule is when the offeror is contractually bound because the offeror has received some “consideration” to keep a certain offer open for a fixed amount of time. Even if the offeror states in the offer that the offer will not be revoked, or even if the offeror voluntarily gives the offeree a specified amount of time to accept the offer, the offer may be revoked at any time prior to acceptance unless it is an independent contractual promise duly supported by consideration. Revocation of an offer must be communicated to the offeree to be effective. However, the communication may be made either expressly or simply by conduct inconsistent with the offer, such as selling property that is the subject of the offer. If the revocation is expressed, it is effective when the offeree receives the notice of revocation. The offeror may dictate the manner, time, and place of acceptance of the offer. An offer whose manner, time, and place of acceptance is dictated by the offeror becomes a binding contract only when it is accepted according to its terms. Thus, an offer not accepted in a timely or proper manner lapses. The offeror may, but is not compelled to, waive strict compliance with the provisions of the offer concerning acceptance. Thus the offeror may waive compliance with a provision specifying a time limit for acceptance, even if the contract states that time is of the essence. If no time is fixed for acceptance, an offer will lapse if it is not accepted within a “reasonable time”. What a “reasonable time” depends on all the circumstances existing when the offer and any attempted acceptance are made, including the nature of the proposed contract, the purposes of the parties, and the course of dealing between them. A “reasonable time” is the time necessary to do conveniently what the contract requires to be done, as soon as circumstances permit. When an offeree rejects an offer, the offer is terminated and it may not be revived by a later attempt at acceptance. A counter-offer that relates to the same subject matter as the original offer acts as a rejection of the original offer unless, at the same time, the offeree states in express terms that the offeree is still keeping the original offer under consideration.
An “acceptance” must be identical to the offer; otherwise, there is no binding contract. As a general rule, an acceptance must not change or qualify the terms of the offer; an attempt to do so results in a counter-offer rather than an acceptance. A purported acceptance that contains a new demand, proposal, condition, or modification of the terms of the offer ordinarily is not an acceptance; it is a counter-offer and a rejection. The materiality of the altered term is key, however, and an immaterial variation between the offer and the acceptance will not prevent the formation of an enforceable agreement. An offeree cannot accept an offer to form a contract unless the terms of the offer are reasonably certain. When an offer prescribes the manner of acceptance, its terms must be followed precisely to create a contract. An offeree’s use of a different method of acceptance is not effective unless the offeror subsequently manifests to the offeree the offeror’s consent to this different method. When a counteroffer is made, any specific manner of acceptance required by the original offer does not apply to the original offeror absent clear specification in the counteroffer’s terms. When an offeror makes an offer without specifying a required manner of acceptance, the offeror impliedly authorizes an acceptance in the same manner used to present the offer. The offeree need not always adopt the manner of the offer as the manner of acceptance. When the manner of acceptance is not specified in the offer, the offeree may accept according to any established usage and custom found in similar cases. If proof of an established custom or usage is not available, the courts will consider what is “reasonable” under the circumstances. Although there are few rules as to when a particular manner of acceptance is sufficient in a specific situation, the important consideration is whether the mode of attempted acceptance used actually informs the offeror that the offer has been accepted. For example, offers are often accepted by mail. Acceptance by mail is usually permitted either when the offer has been delivered by mail, or when acceptance by mail is reasonable under the circumstances. An oral offer may be accepted by execution of a written instrument that embodies the terms of the agreement. Similarly, a written offer may usually be accepted orally. Acceptance may also, in most cases, be shown by conduct such as where the offeree actually performs its obligations under the agreement. Acceptance may even be shown by silence, provided that the circumstances of the case are such that it may be inferred that notice of acceptance is not required. Silence is also sufficient when the offer is one to enter into a unilateral contract. Such an offer envisions the offeree accepting not by making a reciprocal promise but by performing the act requested by the offer. If a written offer relates to the sale of land or the lease of land for a term of one year or longer, the acceptance must be in writing in order to form a binding contract under the statute of frauds. An acceptance is effective only if made before an offer is revoked or lapses. When an offer prescribes the time for acceptance, its terms must be followed precisely. An offer accepted at a time other than prescribed in the offer is effective only if the offeror waives strict compliance with the time provisions of the offer. An acceptance takes effect and creates a contract when the acceptance is communicated to the offeror. An acceptance is not effective when some abstract conduct other than communication with the offeror occurs. For example, signing documents does not constitute a binding contract or bind the accepting party when the offeror does not know about the signing. The accepting party may change his or her mind until the act of acceptance is actually communicated to the offeror. Although an acceptance is effective only when communicated to the offeror, when an offer may be validly accepted by mail, the “mailbox rule” provides that the communication has been made and the contract is binding when the offeree deposits a properly addressed letter of acceptance in the mail, regardless of whether it is actually received by the offeror. If mailing is a proper method of accepting an offer, the “mailbox rule” will not apply only if the offer specifies that a mailed acceptance does not become effective until it is actually received.
Determining when an offer or acceptance is made can be complex and depends on the circumstances of each case. The courts may use principles of fairness, the intentions of the parties, or public policy in determining whether an agreement exists. If you have questions about whether there has been a valid offer or acceptance in a transaction to which you are a party, you should consult with an experienced Texas contract attorney for an evaluation of your situation.
