Lesson 4: Offer and Acceptance

Understanding contracts can be as fun as a courtroom drama... or a comedy, depending on how you look at it!

Understanding the concepts of offer and acceptance is crucial in the study of contract law. These elements are foundational to the formation of a legally binding contract.

Offer

An offer is a clear proposal made by one party (the offeror) to another (the offeree) to form a contract. The offer must be communicated, and it must contain definite and certain terms. An offer signifies the offeror's willingness to be bound by the terms of the proposal if the offeree agrees to them.

Elements of a Valid Offer

  • Intention: The offeror must intend to be bound by the offer.
  • Definiteness: The terms of the offer must be clear and definite.
  • Communication: The offer must be communicated to the offeree.

Acceptance

Acceptance is the unqualified agreement to the terms of the offer. For acceptance to be valid, it must meet the following criteria:

  • Mirror Image Rule: Acceptance must be unequivocal and must exactly match the terms of the offer.
  • Communication: Acceptance must be communicated to the offeror. Silence does not constitute acceptance unless agreed upon by both parties.
  • Method of Acceptance: The acceptance must be made in the manner specified by the offer, if any. If no method is specified, any reasonable method is acceptable.

Termination of Offers

An offer can be terminated before acceptance. The following are ways in which an offer can be terminated:

Think of these as the "deal breakers" in the world of contracts:

  • Revocation: The offeror withdraws the offer before it is accepted.
  • Rejection: The offeree rejects the offer.
  • Counter-Offer: The offeree makes a counter-offer, changing the terms of the original offer.
  • Lapse of Time: The offer expires if a specified time limit passes or after a reasonable time if no time limit is specified.
  • Death or Insanity: The offeror or offeree dies or becomes legally incapacitated before the offer is accepted.
  • Illegality: The offer becomes illegal before acceptance.

Special Acceptance Rules

There are specific rules that apply to certain types of acceptances:

Mailbox Rule

The Mailbox Rule, also known as the Posting Rule, states that acceptance is effective when it is dispatched, not when it is received by the offeror.

Unilateral Contracts

In the case of unilateral contracts, the offeree's performance constitutes acceptance. The offeror cannot revoke the offer once the offeree has begun performance.

Silence as Acceptance

Generally, silence does not constitute acceptance. However, there are exceptions:

  • Previous Dealings: If the parties have a history of silence as acceptance, it may be valid.
  • Benefit Received: If the offeree accepts a benefit knowing the terms, silence may constitute acceptance.
  • Express Agreement: If both parties agree that silence will be acceptance, it is valid.
