PRINCIPLE STATEMENT

Whether it is reasonable to infer an agreement between parties who have engaged in negotiation depends on whether there has been an offer which has been accepted in the manner required by law; all circumstances must be considered to determine if one party may reasonably be assumed to have made a firm offer and if the other party may likewise be taken to have accepted that offer; an offer, capable of being converted into an agreement by acceptance, must consist of a definite promise to be bound provided that certain specific terms are accepted.

EXPLANATION / SCOPE

Contract formation during negotiations requires identifying: (1) a firm offer—definite promise to be bound on specified terms; (2) acceptance—agreement to those terms in the required manner. Courts examine all circumstances to determine: was there a firm offer (not mere negotiation, invitation to treat, or preliminary discussion)? was it accepted (expressly or by conduct)? “Definite promise to be bound” means: commitment, not continued negotiation; specificity on essential terms; and readiness for immediate binding effect upon acceptance. “Certain specific terms” means fundamental terms are identified. The test is objective: would a reasonable person, considering all circumstances, conclude a firm offer was made and accepted? This prevents: forcing contracts from mere negotiations, binding parties who were still negotiating, or finding contracts where parties intended further discussion. Mere negotiation, discussion of possibilities, or exchange of proposals don’t create offers unless showing definite commitment. This framework protects: freedom to negotiate, clarity about when commitment arises, and prevents premature contract formation during preliminary discussions.
