Contracts Outline

Offer Study Outline

This outline discusses the essential elements of a valid offer in contract law, including types, requirements, and relevant case law.

Definition and Nature of an Offer

An offer is a proposal by one party (the offeror) to enter into a legally binding agreement with another party (the offeree). To create an enforceable contract, an offer must be made with sufficient clarity that a reasonable person would understand it as an invitation to form a contract. An effective offer must include definite terms on which the parties agree to be bound, and it must be communicative to the offeree to establish mutual assent. The offer can be made in various forms, including written, oral, or implied through conduct, however, the terms must be clear enough to allow the offeree to accept or reject them.

Key Rules

  • An offer must be communicated to the offeree.
  • An offer must be definite and certain.
Types of Offers

Offers can be classified into several categories: unilateral and bilateral offers. A unilateral offer invites acceptance through performance of an act, meaning the offeree does not need to communicate acceptance but must perform the stipulated act. In contrast, a bilateral offer consists of mutual promises, where both parties make binding commitments to perform certain actions. Moreover, offers can be distinguished as specific or general, with specific offers directed to a particular offeree and general offers being made to the public at large. Each type carries unique implications regarding acceptance and the formation of a binding contract.

Key Rules

  • Unilateral offers require performance for acceptance.
  • Bilateral offers require a promise in exchange for a promise.
Revocation and Termination of Offers

Offers can generally be revoked by the offeror before acceptance; however, this revocation must be communicated to the offeree. Certain offers can be irrevocable, such as those supported by consideration (option contracts) or those made under a firm offer in the UCC. An offer also terminates upon lapse of time, rejection by the offeree, or a counteroffer which negates the original offer. Understanding the mechanisms through which an offer can be effectively revoked or terminated is crucial as they influence the parties' ability to establish a contract.

Key Rules

  • Offers can be revoked before acceptance unless they are irrevocable.
  • Counteroffers terminate the original offer.
Key Cases
Carlill v Carbolic Smoke Ball CoEstablished the principles of unilateral offers and acceptance, confirming that advertisements can constitute binding offers when they are clear and specific.
Harvey v FaceyClarified the distinction between an offer and an invitation to treat, reinforcing that mere communications of price are not offers but invitations to negotiate.
Exam Checklist
  • Identify whether a communication constitutes an offer.
  • Distinguish between unilateral and bilateral offers.
  • Analyze the terms for definiteness and clarity.
  • Evaluate the circumstances under which an offer can be revoked.
  • Consider the implications of counteroffers on the original offer.
