A contract is a promise or a set of promises for the breach of which the law gives a remedy, or the performance of which the law in some way recognizes as a
duty.
Parties have a duty; all must know the law and perform to its duty. An agent has the duty to know the law and how it is to be applied. The target has a duty to know the law and how it is to be applied.
It is the element of agreement that distinguishes contractual obligation from many other kinds of legal
duty (such as the obligation to compensate for negligent injury or to pay taxes) (Contracts Examples & Explanations, § 1.2.1, pg., 3)
An offer is the manifestation of willingness to
enter into a bargain, so made as to justify another person in understanding that his assent to that bargain is invited and will conclude it.
What a minute what if the offer (law) apply to me? What to do?
ACCEPTANCE… Conditional. An engagement to pay the bill on the happening of a condition. . . . Black's Law Dictionary, rev. 4th ed., s.v. "Acceptance."
