Form of Offer


An offer is an invitation to enter into a relationship or transaction of some kind.

  • person who makes an offer is an offeror
  • other party is an offeree

Requirements of a Valid Offer

  • Specificity: The offer must clearly state the essential terms and details of the proposed agreement (material terms)
    • ensures the offeree understands what they are agreeing to
  • Communication: The offer must be communicated effectively to the offeree

Duration of an Offer

  • offer is valid as soon as the offeree receives it
  • offer remains open until it is accepted, rejected, or retracted
  • If an offer does not include a time period, then it expires after a reasonable period of time
    • Courts determine what a reasonable period of time is

Responding to an Offer

  • Acceptance
    • The offeree agrees to all the terms of the offer, creating a binding contract
  • Rejection
    • offeree does not agree to the terms of the offer
  • Counteroffer
    • If offeree proposes new terms, the original offer is rejected
    • cannot go back to original offer unless proposed again
  • original offeror can revoke an initial offer
  • offer can be canceled before acceptance

Form of Acceptance

  • offer is accepted when the offeree agrees to the terms of the offeror’s bargain
    • offeree must clearly communicate acceptance:
      • “Yes” or “I accept”
      • can be communicated through actions
        • paying money

Mirror image rule means that even a small change in terms or language between the offer and an acceptance served as a rejection of the original offer.

  • new terms in the acceptance then become a counteroffer
  • less emphasis on the mirror image rule today
    • acceptance does not have to be identical to an offer to be enforceable
    • acceptance is viewed as a counteroffer only if the terms of the acceptance change a material term in the offer
  • UCC follows the relaxed mirror image rule

Timing of Acceptance

  • timing of the acceptance is an important consideration under the common law of contracts
    • A contract is automatically formed when the offeror receives the acceptance
    • for delayed communications,
      • mailbox rule means that an offer is deemed accepted for legal purposes as soon as an offeree puts a written acceptance into the mailbox
      • acceptance is valid as soon as it is dispatched or sent
      • applies to electronic communications such as email
      • unless offeror specifies a specific way to accept
