Whether the Smiths' signing of Behee's written offer created a binding real-estate contract before Behee withdrew the offer.
Holding
No. No contract arose because the Smiths did not communicate their acceptance to Behee before he revoked his offer.
Reasoning
Under Missouri law, an offer that calls for a promise rather than performance does not become a contract merely because the offeree privately decides to accept or signs the proposed agreement. Acceptance must be communicated to the offeror. Thus, the Smiths' uncommunicated signing of the offer on March 4 was not, by itself, an effective acceptance.
Behee had received no notice of the Smiths' acceptance when he notified their real-estate agent that he wished to withdraw his offer. Notice given to an authorized agent is notice to the principal, so the agent's receipt of Behee's withdrawal was legally effective against the Smiths.
Behee's offer was not supported by consideration that would have made it irrevocable. He therefore remained free to revoke it at any time before acceptance was communicated to him. Because the withdrawal reached the Smiths through their agent before Behee received notice of acceptance, the offer was properly revoked and no binding contract existed.
